SPC self-adhesive waterproofing membrane cross price I. Introduction and Introduction Figure 1, the product description SPC self-adhesive waterproofing membrane cross sections with SPC node carrying waterproofing membrane is formed by changing the shape of the pre-shaped articles. Bond peel strength reaches node profiles 15N / cm or more. Construction materials node operation is very simple, easy to guarantee quality, very effective to eliminate bending notches for waterproofing when dealing with complex parts, etc., causing leakage risks exist. Products are divided into different to the angle, with the angle, straight and curved hems round convex type four kinds of predetermined profiles. 2, product image Second, the preparation of SPC self-adhesive polymer cement waterproof adhesive material is a paste waterproof layer, SBC adhesive usual content of 3% by weight of cement, namely a bag of cement (50kg) equipped with a bag of adhesive (1.0 kg). Preparation of the adhesive and 6kg ~ 10kg bag of cement dry mixed evenly, then stirring slowly added to 27.5kg ~ 32.5kg of water (equivalent to 56% to 65% by weight of cement, namely 2.5 outer packing volume), gradually stir after adding the rest of the cement, while adding little cement stirring, stirring until no clots, no precipitation, no air bubbles can be used. 2, SPC cross-film self-adhesive waterproof membrane should be formulated Note: ① the amount of water, the large plastic bag inside the box catchy turn to the tank, the measurement by marking the inside of the crate. ② to adjust the degree of polymer cement waterproof adhesive viscous material according to project specific paving site. ③ formulated polymer cement waterproof adhesive material should be used up within four hours, and appropriate based on water evaporation add water to reconcile the situation. Three, SPC-adhesive composite waterproof membrane construction specifications: 1.2mm 1.5mm, 2.0mm thickness of 1.2mm, 1.5mm, 2.0mm Weight: 45kg Others: single, double, Ⅰ type, Ⅱ type, wet-laid, pre-shop wet-laid process, wet laid type, pre-shop law, pre-shop type 1, SPC-adhesive composite waterproof membrane construction must be carried out after acceptance screed. SBC series composite waterproofing membrane paste, the moisture content of the grass-roots level, no special requirements, as long as no clear water to construction. If the phenomenon of time out of water, polymer cement waterproof adhesive material may be too diluted, the adhesive layer appeared thin, uneven, sticky leakage phenomenon, will roll bond strength and construction quality impacts; but if the grass the moisture content is too low, it will cause polymer cement waterproof adhesive material can not be fully hydrated, resulting in the adhesive layer or adhesive strength reduced chalking. Engineering Practice has proved that when the moisture content of 30% to 50%, the effect of construction composite waterproofing membrane SBC series best. 1) sheet lap joints ① Coil lap width: roofing projects, the long side, the short side lap width should not be less than 80mm; underground works, the long side, the short side lap width should not be less than 100mm. ② adjacent short side seams should be staggered 1m above the level of the corner (the angle between the wall and the wall) from the seam angle is more than 0.3m, an additional layer of joints must be waterproof layer joints staggered over 0.3m. ③ underground works, roll joints should be staggered around the corner, the joint position should be more than 0.3m from the corner, at a vertical angle (the angle between the wall and floor) membrane joints should be on a level surface, the seam position margins Corner 0.6m above. 2) Before treatment of complicated parts of the waterproof layer construction, should first make drawings of complicated parts (roof protruding parts, gullies, gutters, eaves, gutters; underground waterproof Yin Kok, Yang angle, wall tubes ) additional layer, additional layers of complex parts with SPC-adhesive composite waterproofing membrane (membrane visual engineering specifications determined), polymer cement bonding process. 3) The node profiles reinforcing layer construction requirements grass and node profiles simultaneously coating thickness are about 1.2mm. Paste the area should be ≥95%. 4) SPC self-adhesive waterproofing membrane Stones cross ① SBC series composite roofing waterproofing membrane paste Fang Xiangyi according to GB 50207-2002 "Roof Engineering Quality Acceptance" Article 4.3.5 shall be determined, underground works and paste direction determined in accordance with the actual situation. When the Stones roll, first in paving the web site of the pre-release 3 ~ 12m, to find a positive direction, is fixed in the middle of the coil is fixed at one end of the roll to paste, paste side after it is completed, then the pre-release The other end of the web roll back to the pasted good location, continuous paving until the completion of the whole site. Fourth, paving method ① scraper binder polymer cement waterproof coating on the substrate (leveling layer) surface to a thickness of 1.2mm (polymer cement brushing should be uniform, not open at the end, do not build up), and then paste the web . At the same time on the web surface with a squeegee the adhesive surface of the exhaust compaction, discharge the excess adhesive glue, which is crucial to ensure the quality of the project. ② SPC series composite waterproofing membrane when used in a longitudinal vertical plane must be pasted from the top down on the positive, from the bottom up exhaust compaction, requires grassroots and the web simultaneously coating thickness are about 1.2mm ③ SPC self Cross waterproofing membrane damage defect should do an additional layer, an additional layer membrane surrounding the defect should be wider than 120mm. The additional layer should be waterproof polymer cement binder full of sticky. Fifth, the product protection 1) the completion of the waterproof layer, polymer cement binder before curing procedures shall jobs in their walk on or after. 2) After completion of the waterproof layer should be avoided in which the bore holes. 3) The current procedure or an adjacent construction project, has been completed for the waterproof layer should take appropriate protective measures. Sixth, transport and storage 6.1 when the web transport and storage, should prevent the sun, water, mechanical damage, high fever. 6.2 monolayer sheet should stand up (storage period of less than 30 days may be two stand up) for a period of less than 20 days shipping stack up to level five. Do not touch with a variety of web 6.3 organic solvents and other harmful substances. Seven production base Niu Xugong Zhang Publisher
