Color steel plate construction steps:
Acne Patch5
The main material of acne pimpel patch is hydrocolloid, which is composed of hydroxymethyl cellulose, medical hot melt adhesive. Acne patch box is used to apply to the surface of acne, absorbing tissue secretions in a physical way and creating a moisture-balanced environment around the acne. Acne patch kingson has a flat back and neat edges, with no defects of decoupling. Cute acne patches can absorb more than twice of its own tissue fluid. Private label acne patch is disposable. Keep skin clean before product use, do not apply any products, do not use with ointment. Hydrocolloid acne pimple patch for zits is most effectively absorbed when the acne appears pus-filled. To use rael acne pimple healing patch, remove the sticker, peel off the backing paper, apply it to the wound and gently press around it to fix it. Acne patches korean is most effectively absorbed when the acne appears pus-filled. To use acne healing patches, remove the sticker, peel off the backing paper, apply it to the wound and gently press around it to fix it.

1. Before installation, the dust, dirt, alkali film and other materials on the surface of the base should be carefully cleaned.
2. The process of decoration and installation of color steel plate partition wall is carried out according to the principle of “first down and then on†to reduce repair and protect the finished product.
3. Sealed with the same color sealant at the joint of the wall.
4. The surface is cleaned after the wall is installed.
Color steel plate quality requirements:
1. The wall panel should be installed vertically and the top panel should be installed horizontally.
2. The process seam is even and the sealant should be enriched.
3. There must be no scratches on the surface of the slab.
Color steel plate construction requirements:
1. Familiar with the clean room drawings, carefully review the layout of the color steel plates, the requirements of the nodes, the association between the color steel plates and the buildings, the color, fillers, basic size requirements of the color steel plates themselves, the size and arrangement of the doors and windows in the color steel plate partitions. Types of auxiliary materials and other unknown content.
2, secondary plate drawing, this is an important step in the prefabrication and installation of color steel plate, is to convert the design drawings into the second processing in the factory, the standard specification plates are made into different types of wall panels, combined to reflect The intermediate conversion map of the design intent, and the production of standard plates in the color steel plate factory, assembled at the construction site, can ensure the firmness of the wall plate and accelerate the installation speed of the color steel plate.
3. When prefabricating in the clean room factory, according to experience, the clearance and installation margin are fully considered between the door hole, the window hole and the seam. In the entire transportation production and installation process, scratches, heavy pressure and surface impact are prevented to prevent uncorrected pits and scratches. The plastic protective film on both sides of the color steel plate can only be torn off after thorough cleaning after the installation is completed.
4. The discharge work before the installation of the clean room color steel plate shall be carried out after the completion of the ground (floor) surface, and other relevant conditions for installation, such as the larger equipment has been transported in place, the dark ground pipeline has been adjusted and the technical interlayer The main installation work is basically completed before it can be carried out. The line is drawn on the ground with a horizontal projection of color steel plates (50mm wide) and door and window positions. The center line of the upper and lower mangers should be within 1.0% of the error on the same vertical plane, ie 3mm.
5. Install the upper and lower mangers. The lower manger is generally made of aluminum alloy profiles with internal and external R angles. Fix the nail on the line drawn on the ground. The position of the nail is 1.2-1.5m in line, the corner and the distance from the end are 0.2m. Use the rubber strip to seal the two strips before the nail is shot. Ф 2-3) Put it under the groove and form a waterproof isolation seal after the nail is fixed. The upper manger is used to press the tank aluminum, and the hard ceiling is fixed on the top plate with a nail gun. The soft ceiling is suspended by the boom under the level, and the height is based on the ceiling height.
6. The vertical siding is loaded into the prefabricated components according to the layout, and the adjacent panels are locked by the fixing inserts between the components. It is worth paying special attention to the electrical dark pipeline and box when assembling the siding. The wall panels should be vertical, the vertical joints should be tight, the smaller the gap, the more beautiful, and the vertical seams should be even. During the operation, carefully clean the protective film on the vertical seam and temporarily remove it, and never remove it. Clean up the debris in the tank and the glued solidified hard block. Otherwise, it is difficult to adjust the uniformity and compactness of the vertical seam with a large force.
7. Install the clean room ceiling plate: The weight support of the top plate is through the T-shaped aluminum fixed in the surrounding vertical plate and suspended in the middle. The long-edge seams are fixed and reinforced by fixing inserts, and the short sides are fixed by T-shaped aluminum and connecting plate blind rivets. The flat top is flat and the seam is even, smooth, no trace and no damage. Pay attention to the same siding.
8, color steel plate column, box, with yin and yang R angle
The pillars in the purification zone are wrapped with б=50 color steel plates to help save material and the uniform yin and yang R angles are 50. Firstly, the stainless steel door and window frame is fixed in the door and window opening to securely fix the door, pay attention to the opening direction, and install the window glass. The door closer should adjust the opening speed and strength. Generally, the first half speed is fast when the door is closed, and the second half torque is small and the speed is slow to reduce the door impact and noise.
9. Sealed silica gel: In the purification zone, all the following gaps that may affect the cleanliness should be coated with sealing silica gel: the joint between the color steel plates, all the gaps between the R angle and the wall and the roof; air conditioning duct , the tuyere, the gap between the high-efficiency filter and the wall top plate; the gap between the protective pipe groove and the edge of the hole that electrically passes through the top plate of the wall plate; the gap between all the switch socket lamps and the top surface of the color steel plate; all processes, water supply and drainage, protection The gap between the tube and the hole; the gap between the glass and the frame; the sealing silicone should be basically installed in the color plate, and the sanitary condition is good. After thorough cleaning and dust removal, the clean room is uniformly carried out. Otherwise, the silicone seam is easily contaminated and blackened. Within 24 hours after the silica gel is applied, there should be no excessive dust operation and washing the ground with water, which may affect the curing and fastness of the sealed silica gel.
