Popularity:4 Release time:2022-05-25 09:49:01

ISO14644-1 clean room engineering construction is a systematic project, usually in the large space created by the main structure of the civil framework, using the required decoration materials, according to the process requirements to separate and decorate into ISO14644-1 that meets various use requirements Cleanroom. The pollution control in the ISO14644-1 clean room needs to be completed by the purification air conditioning major and the automatic control major. What are the details of ISO14644-1 clean room engineering construction?

First, the design concept

Simple and elegant appearance, advanced equipment, to create a safe, clean, environmental protection and energy saving, warm and quiet experimental and production environment.

Two, ISO14644-1 clean room engineering color steel partition technical requirements

Height and noise requirements: ISO14644-1 clean room ceiling and clear height of 3 meters in the air, ISO14644-1 clean room noise ≤ 60dB. Relative humidity: 40%~60%, temperature 22℃±3℃, not exceeding the upper limit in summer and not lower than the lower limit in winter.

Color steel plate wall and ceiling: The partition wall in ISO14644-1 clean room is made of high-quality double-sided composite sandwich purification color steel plate and glass window partition wall. The partition wall must reach thermal insulation, sound insulation, anti-corrosion, fire prevention, easy cleaning and disinfection. The junction between the color steel plate wall and the air and color steel plate walls is treated with an epoxy resin sprayed aluminum alloy arc with a radius of not less than 30mm. Color steel plate joints should be sealed. The sealant needs to use imported medical sealant, and must not produce volatile toxic gas. The surface coating of the color steel plate, the arc epoxy resin spraying material and the seam sealing material must have antistatic properties, which can prevent harmful particles from being adsorbed to the surface of the wall. Before installing the color steel plate, a trial pendulum is required. The aisle partition wall adopts the half-height double-layer tempered glass window treated with imported alumina (the double-layer glass contains adjustable aluminum alloy shutters). The glass thickness is 8mm, and the lower edge is 1100mm from the ground. 12mm sandblasted tempered glass is used for the distance between the area and the outer wall.

ISO14644-1 PVC rubber for clean room air: DNAISO14644-1 clean room adopts ISO14644-1 clean room special PVC coil, thickness ≥ 2mm, the air and the wall are connected by an arc of R ≥ 50mm, special ISO14644-1 clean room PVC The rubber air has the effect of being safe, non-toxic, resistant to pollution and chemicals, and is easy to clean. The joints of the PVC rubber air are seamlessly connected by special welding rods. The color should be confirmed by the customer after the winning bidder enters the field.

3. Floor construction technical plan

Unwinding schedule

1. When the discharging group enters the site for construction, the acceptance inspection of the entrusted site of the foundation disposal group shall be suspended first. After the two parties terminate the acceptance communication procedures, they shall apply to the supervisor for pre-inspection, and the construction can be terminated before the pre-inspection is passed;

2. The personnel of the unloading team must know the light source, size, shape of the site, the requirements of Party A, the laying order of the laying group, and the material status, etc., make arrangements in advance, and construct according to the drawings, in line with the principle of economy. To arrange materials, reduce losses, and use waste as much as possible. Note that the direction of the arrow on the reverse side of the PVC floor must be different;

3. The material blank must be placed in the feeding group, and the door card, wall corner, etc. must be punched. On the principle, the punch card must be consistent with the basic line, the gap should not exceed 1mm, and the lines should be fluent. At the same time, pay attention to whether the height of the floor material and the door It is suitable, and the handling of the connection with other materials, but all the stitching of the arranged materials is left to the laying group push knife, the overlapping part of the stitching guideline is 50px, and the plate close to the light source needs to be placed on it, and the burrs should be placed on it. under. The seam on the yardstick is perpendicular to the light source, and the material is discharged in a special situation, special treatment;

laying regulations

1. When the laying group enters the site, it is necessary to check whether the materials of the unloading group can be used reasonably, whether the punch cards can be matched, whether the data can be placed correctly, whether the lap joints can be accurate, etc. to stop the acceptance, complete the handover procedures, and understand the unloading group. attempt.

2. The laying must be stopped in the blocked site, and idlers are not allowed to enter the construction site, so as not to bring in sediment and sundries, which will affect the laying quality. The laying team operators are only allowed to enter the site wearing flat soft shoes, or bare feet, not Hard-soled shoes are permitted to enter the venue.

3. When entering the operation, the push seam must be stopped by a ruler. The depth of the blade of the adjusting pusher should be the thickness of the two floors and then 0.5mm longer to ensure one-knife inference and prevent the interface from not matching. PVC floor waste must be used under the large pressure plate of the pusher. The pad is flat to prevent the tool from skewing, resulting in an inclined cross-section of the knife edge. When pasting, the seam is not smooth, not fluent, and there is a height difference.

4. Regarding the configuration of glue, it must be strictly suspended according to the proportion, and random configuration is not allowed, because random configuration will affect the bonding strength of glue, lack of response or excessive response. The glue must be stirred sufficiently to ensure that the curing agent is in even contact with the glue and has a sufficient response. The stirring time is about 2 minutes. During the stirring process, the stirrer should not be placed in a high-speed gear to increase the temperature of the glue and speed up the response. At the same time, it should be Turn it up and down to ensure that the curing agent deepens into the underlying glue. The mixing ratio of curing agent and glue is 1:5 by weight.

5. Measure the laying area before mixing the glue, and then confirm the amount of glue, and strictly configure the proportion, so as not to waste. Certainly good laying procedures, programs. Stop squeegeeing according to the principle of applying glue first and then laying it. For the joints of the two groups of glues, stick them with paper tape. After the glue is scraped, tear it off to ensure that the glue openings are uniform. The position of the paper tape should be considered first. Well, do not choose a place where the light is strong and conspicuous. At the same time, the second group of glue and its interface should be wet-bonded at least 500px first, and then immediately press the glue at the interface with a hand roller to flatten it vertically along the glue mouth. , and the rubber surface of the first barrel should be as smooth as possible, otherwise, an obvious interface surface will appear in the rubber air, which will affect the appearance. For the material above 3.5mm on the guideline, use A2 tooth rubber scraper, 2mm material, if it is on the first floor, use A2 tooth, and above the second floor, use A1 tooth, but before operation, it is necessary to check the rack wear level. In particular, the A1 rack wears quickly and needs to be checked and replaced in time.

6. Regarding each batch of glue, the laying plan should be formulated according to its different response speed. It is strictly forbidden to operate first, and the operation behavior of the previous plan is strictly prohibited. After a small area experiment, grasp the cooling time of the glue, and keep the glue surface clean. Taking the drawing state of the rubber surface as the laying opportunity, at the same time, the size of the area should be considered, and the laying time should be determined.

7. After reaching the predetermined amount of glue time, the laying should be stopped from the end with stronger light. After laying a certain datum plane, other plates should rely on this datum plane, and the seams close to the datum plane block should be spliced correctly. , and then press the air bubbles to the other side to ensure that the PVC floor is implemented, and the contact with the glue surface is stopped to ensure that the glue is evenly transferred to the reverse side of the PVC floor. In order to ensure the elimination of accumulated errors during laying, it is necessary to leave a seam (including horizontal and vertical) and push the seam tightly after laying, so as to complete the laying and compacting procedures in a short time. The seam overflow phenomenon must be cleaned with liquid wax immediately. When laying blocks, emphasis should be placed on the seam parallel to the side light, and the glue seam line should be perpendicular to the side light to prevent the glue opening in a prominent position.

8. During the laying process, the operator should stand on the footing board from time to time. The size of the footing board is 1m long, 1125px wide, and 42.5px thick. It is not allowed to step on the laid PVC floor directly to form The glue is unevenly spread, bubbling, and uneven. During the entire laying process, a person must guide the laying at the position where the defects are most easily seen (such as viewing from the light-facing position), and adjust the problems in the laying in time.

9. When handling the seam, the small pressure roller should be rolled back and forth perpendicular to the seam line, and the rolling interval should be at least 1125px or more. If it is not in place, it will cause the phenomenon of weak bonding and hollowing. The hollowing phenomenon must be dealt with before the glue dries.

10. After the laying is completed, all other personnel will be withdrawn. On the ground that has just been laid, stop the master from stepping on it within 1 hour, and leave a professional roller to press the roller fully after 30-40 minutes. Use a large roller for the roller, and a small roller can increase the load to stop the rolling. The roller presser should minimize the walking area, play the role of the long arm of the roller, roll back and forth, and try to prevent the phenomenon of empty drum and virtual glue. This step is repeatedly suspended for a period of time depending on the temperature conditions.

11. After the pressing roller procedure is completed, the site should be blocked as long as possible under conditions. People can walk around at least 12 hours after the PVC floor is laid, and stop wet cleaning and waxing after 48 hours.
