Principles of dust removal in the computer room:

Given our case and construction experience in the dust removal industry, we have gained valuable experience in our understanding and

 implementation of the information system of data centers.

The valuable experience we have gained is:

1. Cleaning principle: first the primary equipment, then the key equipment.

2. First make basic business equipment, then make core equipment. (For hot backup dual-machine equipment, clean all backup machines first, and

 then unify the principle of cleaning the main machine.

3. First clean the equipment in the spare computer room, and then implement the principle of the main computer room.

4. The cleaning principle of the computer room: from high to bottom, from the outside to the inside (first start cleaning from the peripheral

 environment of the computer room, start from the bridge, then clean the cabinet, and then clean the equipment.) The cabinet starts from the top and to the bottom.

5. Server and other devices follow the principles from front to back, from outside to inside: from outside the server case, server front panel, server

 internal, server power supply, server rear panel)

6. Ups cleaning principle: first the battery, then the host machine.

7. Principles for cleaning electrostatic floors: first clean the underground and beams of the electrostatic floor, and finally make the surface of the 

electrostatic floor. Adopt cover technology.

8. Clean one device and protect one to avoid contamination from each other. Masking technology is adopted.

4. Construction progress of fine cleaning service:

1. Preparation work before construction:

(1) Data center area, data center No. 4.8 floor, data center No. 5.8 floor, data center No. 6.8 floor, and data center No. 6.8 floor, the floor of each 

computer room with electrostatic floor must be laid with coverings to protect electrostatic floors.

(2) All cabinets and battery racks in the computer room must be masked for protection and isolation.

(3) The doors of all rooms in the data center area, data center No. 4.8 floor, data center No. 5.8 floor, and data center No. 6.8 floor, masking technology 

is used to isolate each room and the aisle, due to secondary pollution caused by construction.

2. Project progress plan and measures

2.1.1 Project Progress Plan

The construction progress is ensured by using a three-level quality inspection system of the construction team, project department, and company quality inspection department.

2.1.3. Human resources

In order to organize the construction reasonably, based on the characteristics of the project and the long-term construction management experience of our company, we plan to invest in: 1 project manager, 10 construction workers, 1 safety officer, a total of 12 people.

2.1.4.2 Formulation of project construction progress goals

Before carrying out project progress management, the management team will plan progress management in advance as a 

summary and outline of the project management plan.

The following management process groups will be involved in the progress management process of engineering projects, 

and the basis, tools and results will be involved in several project progress management activities or processes.

Ø Activity definition

Determine project deliverables and provide a basis for project progress estimation, arrangement, implementation and

 monitoring. During the process of defining the progress management activities of this project, the project work combination

 is further broken down into smaller and easier to manage based on factors such as the resource conditions of each area and 

the external environment, based on factors such as the resource conditions of each area and the external environment, and the 

project work combination is further broken down into smaller and easier to manage planning activities, providing detailed

 information for further clarifying the work content, thereby obtaining a list of work content for the progress management 

of this project and clarifying the management tasks.

Ø Activity sorting

Identify the list of known activities and record the logical relationship between planning activities. Appropriately consider 

logical relationships such as tight front, tight back, advance, and lag, and formulate a practical project schedule. In terms of 

consideration and arrangement of logical relationships, fully use computers and project management software to work to

 improve work efficiency and avoid errors.

Ø Activity resource estimation

Determine what resources to use during project implementation, the number of each resource to be used, and the time it 

takes to be invested in the project. When allocating and estimating to project activities, economics must be taken into account 

and the principle of meeting project requirements and saving costs must be achieved. Determining the type and number of 

resources is the basis for resource consumption time.

Ø Activity resource duration estimate

The estimation of resource duration is a process of gradual refinement and improvement. We must fully consider the 

accuracy of the original data. Whether the original data is accurate is crucial to the accuracy of the activity plan estimation. 

The estimation table needs to have a certain range, providing a solid foundation for formulating a progress plan.

Ø Develop a project schedule

Based on the definition and sorting of project activities, the estimated resource requirements and investment time of the 

project, a construction progress plan will be formulated. Use network analysis technology, key line method, progress

 compression technology, hypothesis scenario analysis, resource balance chart, key chain technology, etc. to obtain the

 project schedule. Provide an important basis for project progress control.

2.1.4.3. Engineering construction progress management method

We plan to use the following methods to comprehensively control the progress management of this project to ensure the

 smooth development of the project, implement it according to the progress, complete the planned progress goals, and 

deliver it to the construction party for use on schedule.

Ø Gantt chart (cross-track chart) method

Ø Critical Path Method

Ø Plan Review Method

2.1.4.4 Project construction progress control method

The construction stage is the formation stage of the engineering entity and the stage in which we implement the prepared 

construction progress plan.

Ø Decompose according to the construction stage to highlight the control nodes.

Taking key lines and sub-critical lines as clues, and using the planned starting and end milestones as control points, key control

 objects are determined at different construction stages, and construction details are formulated to ensure the realization of the control nodes.

Decompose according to professional job types and determine the handover time.

Ø Comprehensive balance between tasks of different majors and different types of jobs, emphasize mutual coordination and

 coordination, determine the date of mutual handover, strengthen the seriousness of the construction period, and ensure that

 the progress does not cause delays in this process. The quality and time of each process are controlled to ensure the progress

 of each branch project.

According to the time requirements of the total progress plan, the overall construction progress plan is broken down into 

weekly and daily plans, and dynamic control of the progress plan is implemented.

Anti-static floor finishing

Anti-static floor trimming involves the use of approved anti-static floor finishes on inactive floor surfaces to prevent 

dangerous buildup of static electricity. Manufacturers of high pressure laminated (HPL) access flooring strongly recommend 

not applying floor wax to the surface of access flooring.

The subfloor encapsulation includes applying an epoxy coating on the surface of the concrete subfloor boost chamber, 

which acts as a vapor and dust barrier. Epoxy coatings should be applied manually to the surface of the subfloor. Installing 

subfloor sealant is one of the best ways to reduce the concentration of particulate matter in the data center in concrete 

dust and subsequent air.

③Dust removal process and process of electrostatic floor:

③Dust removal process and process of electrostatic floor:

Anti-static flooring, also known as dissipative electrostatic flooring, is a type of flooring that allows charge to be dissipated 

when grounded or connected to any lower potential point, characterized by resistance between 5th power of 10th power to

 9th power of 10th power. "GB 50174-2008 Electronic Information System Computer Room Design Specifications" stipulates: 

The surface resistance or volume resistance of anti-static floors or ground should be 1 × l0 (5) ~1. 0 × 10 Ω.

The anti-static technology of computer rooms is part of the security and protection of computer rooms. Static electricity 

generated by various reasons is one of the most frequent and difficult to eliminate hazards. Static electrostatic not only 

causes random failures, malfunctions or calculation errors during the computer running, but may also lead to breakdown and

 destruction of certain components, such as CMOS, MOS circuits, dual-stage circuits, etc. In addition, static electricity also has a

 significant impact on the external equipment of the computer. Display equipment with cathode ray tubes will cause image

 disorder and blurred when disturbed by static electricity. Static electricity can also cause modem, network card, Fax and other 

work errors, printer printing abnormally, etc.

Not only is the problem caused by static electricity difficult for hardware personnel to detect, but sometimes it is also a

 software personnel mistakenly believe that it is a software failure, which causes work chaos. In addition, when static electricity

 discharges computers or other devices through the human body (so-called ignition) when the energy reaches a certain level,

 it will also give people the feeling of electric shock (for example, sometimes when touching a computer monitor or chassis)

1. Testing before cleaning of electrostatic floors:

First use an impedance meter to measure the [impedance value] of the electrostatic floor of the project and print it out for

 reference.

2 Electrostatic floor front cleaning:

First, use a vacuum suction pump to absorb large dust and pollutants from the entire electrostatic floor, then use a special 

3M floor cleaning agent and a edge machine to clean the surface of the electrostatic floor, and then blow dry with a high-

power blower. (Please dry the excess water.)

3. Clean the back of the electrostatic floor:

Use a special 3M electrostatic floor cleaning agent and clean and dust removal. Remember not to scrub with water. 

(The back of the electrostatic floor is made of steel, and it is easy to rust if you use water)

4 electrostatic floor beam cleaning:

First, use a vacuum cleaner to absorb the dust particles adhered to the crossbeam, and then clean it with 3M special 

neutral cleaning solution. (The electrostatic beams are all copper-plated steel strips, and they will easily rust if they are water)

5 electrostatic floor bracket cleaning:

First, use a vacuum cleaner to absorb the dust particles attached to the bracket, and then clean it with 3M special neutral 

cleaning solution. (The electrostatic brackets are all copper-plated steel strips, and they will easily rust if they are water)

6. Electrostatic floor underground:

 Use a vacuum cleaner to absorb large residue, dust particles or contaminants such as thread under the electrostatic floor. Use 3M neutral cleaning solution with electric mop to clean the hard floor with dust-proof paint.

Anti-static flooring, also known as dissipative electrostatic flooring, is a type of flooring that allows charge to be dissipated when

certain level, it will also give people the feeling of electric shock (for example, sometimes when touching a computer monitor

 or chassis)

1. Testing before cleaning of electrostatic floors:

First use an impedance meter to measure the [impedance value] of the electrostatic floor of the project and print it out for 

reference.

2 Electrostatic floor front cleaning:

First, use a vacuum suction pump to absorb large dust and pollutants from the entire electrostatic floor, then use a special 

3M floor cleaning agent and a edge machine to clean the surface of the electrostatic floor, and then blow dry with 

a high-power blower. (Please dry the excess water.)

3. Clean the back of the electrostatic floor:

Use a special 3M electrostatic floor cleaning agent and clean and dust removal. Remember not to scrub with water. 

(The back of the electrostatic floor is made of steel, and it is easy to rust if you use water)

4 electrostatic floor beam cleaning:

First, use a vacuum cleaner to absorb the dust particles adhered to the crossbeam, and then clean it with 3M special

 neutral cleaning solution. (The electrostatic beams are all copper-plated steel strips, and they will easily rust if they are water)

5 electrostatic floor bracket cleaning:

First, use a vacuum cleaner to absorb the dust particles attached to the bracket, and then clean it with 3M special neutral 

cleaning solution. (The electrostatic brackets are all copper-plated steel strips, and they will easily rust if they are water)

6. Electrostatic floor underground:

 Use a vacuum cleaner to absorb large residue, dust particles or contaminants such as thread under the electrostatic floor. 

Use 3M neutral cleaning solution with electric mop to clean the hard floor with dust-proof paint.

7. Conventional surface treatment for anti-static floors:

Waxing method and construction process:

Regularly adding floor water wax can maintain the durability and anti-static properties of the floor. Before adding floor water wax, use a damp mop to clean the floor and worn areas. It is recommended to add one to two thinner anti-static floor water wax, and there should be sufficient drying time between each layer.

Remove stubborn stains on the ground, isolate the material itself from the air by waxing, reduce the damage caused to the 

material by oxidation or contact with harmful substances in the air, and achieve the purpose of extending the service life of

 the material and being beautiful and smooth.

(1) Necessity for waxing and polishing of anti-static floors:

Remove stubborn stains on the ground, isolate the material itself from the air by waxing, reduce the damage caused to the 

material by oxidation or contact with harmful substances in the air, and achieve the purpose of extending the service life of 

the material and being beautiful and smooth. More importantly, the mirror-bright surface it forms is particularly durable 

and can prevent damage such as detergent, scratches, slips, heel friction, etc. At the same time, after polishing, the wax 

surface is brighter and harder and more resistant.

(2) Anti-static floor waxing and polishing process:

First use the stain-raising and wax-raising water to clean the floor. First use the multi-functional floor brushing machine 

and the vacuum-sucking water suction machine to clean the floor and use a three-speed air dryer to dry it; wooden floors, 

etc. are used to cooperate with the vacuum-sucking water suction machine

Clean dust and electrostatic vacuum cleaner until clean;

Select the corresponding wax water according to the floor material, and waxing the floor with a waxing machine, a water

 press and a wax mop;

l After the wax surface is dried, polish the wax surface;

l Dust removal treatment on the polished ground.

l Make a thorough and comprehensive inspection of the whole to ensure the quality of the project.

(3) Anti-static floor waxing and polishing equipment:

1. Multi-functional floor brushing machine, vacuum and water suction machine, three-speed air dryer, and polishing machine;

2. Water pressing truck, wax drag, dust push, cleaning pad, marble shovel, rag, water bucket, etc.;

3. Wax water, electrostatic vacuum cleaner, all-purpose cleaner, and stain-raising wax water.

8 Special treatment of anti-static floors (local stains):

Since anti-static flooring requires local treatment, ACL-5001 antistatic agent can be used. It is mainly used in dust-free 

machine rooms and has low dust content. It is the best static destatic agent among the current electrostatic agents with 

the best purification effect.

Electrostatic vacuum cleaner, all-purpose cleaner, stain-raising and wax-raising water.

Tools, detergents, and cleaning and maintenance methods required for anti-static flooring.

Cleaning methods for anti-static flooring;

l The tools to be prepared;

． Machines that need to be prepared: one multi-function single wiper, one vacuum and water suction machine, wax 

removal pad (white);

． Tools need to be prepared; two wax moppings, two wax buckets, one oak water bucket, one water push, and a mop;

． Cleaner that needs to be prepared; waxed water 6 gallons, 3M anti-static floor wax 6 gallons;

Work methods and procedures:

1) Wax removal method:

Use a mop to evenly apply the waxed water on the surface of the wax layer. After 5 minutes of action, you will see more and 

more milky white foam. Use a floor scrubber equipped with a wax removal pad to clean the floor.

Clean the floor with a floor scrubber until the wax layer is not visible. If the wax layer is thick, it may not be cleaned at one

 time. You need to remove it with wax water for a second time. Use a water absorber to suck the water dry.

Use a mop and clean water to wipe the floor several times. Be sure to wipe it clean to ensure that there is no residual 

waxed water on the floor to avoid affecting the re-waxing effect.

2) Procedure for waxing anti-static floor wax:

After the ground is completely dry, pour an appropriate amount of anti-static wax into the wax bucket, drag the wax to 

moisten with wax water and twist it dry. According to the principle of from the side to the inside and from the inside to

 the outside, let the wax drag run according to the ∞ shape. Be careful not to dip too much or too little wax each time. 

Apply evenly and do not miss it. After the wax layer is completely dry, apply the second wax as the same method. Dry 

standards: non-stick to your hands and non-stick to your feet. Polish it after it is completely dry: choose a multi-function

 single wiper to polish it with a red polishing pad, and run it slowly during polishing.

Daily cleaning and maintenance:

. Tools required: 2 dust pushes, 2 mop

Cleaner to prepare: electrostatic floor dust collector

Then use dust to push the dust on the floor. If the local dirt is serious, you can wipe it with a moist mop that cannot be

 wrung out of water.

Please note for maintenance: Anti-static floor wax floor cannot be cleaned with water. If water accumulates on the anti-static

 floor wax floor, use a dry mop immediately!

Work cycle suggestions: It is usually done once every three months, the main credentials:

Can work be stopped and waxing can be stopped?

Is it necessary to rewax the wax surface?

Whether the anti-static wax conductivity has decreased and it is necessary to waxing;

Whether the wax layer is damaged by friction.

Note: The brand of the product used anti-static wax brand: 3M, etc.

Cleaner: DR7S01 Strong Waxed Water, DR6G04 Electrostatic Vacuum Refrigerant, LF05 Strong Waxed Water, LR01 Electrostatic 

Vacuum Refrigerant.
