SBS waterproof sheet extrusion line

Waterproof sheet extrusion.

Elastomer (SBS) modified asphalt waterproofing materials, plastic body (APP) modified asphalt waterproof coiled material is polyester tires or fiberglass base, asphalt compound tyres base makings, flexible waterproofing materials in asphalt is tire body with two kinds of composite material, composed mostly of chemical fiber cloth with high alkali glass fiber grid cloth composite, dip coating, mildew resistance, water resistance, durability is poor, so the service life is short, it is mainly used for some temporary buildings or fortification level requirement is not high.The standard clearly stipulates that the asphalt waterproof rolling material made of any modified asphalt, tire base and upper surface material shall not be labeled as "SBS" in addition to SBS coil.

I. packaging identification.The above three materials are not very different from the appearance, so the first thing to look at is the packaging and labeling.It must be indicated on the logo: production name, mark, product mark, production date or batch number, production license number, storage and transportation precautions.Each coil shall be marked and marked in strict accordance with national standards.At the same time, note that the storage period of the coil is generally not more than one year.Look at the fetal base.It can be used to determine whether the matrix is consistent with the mark, whether it is fully saturated and meets the requirements of the standard.The fetus should not he unsaturated white marks or light spots.Polyester tyres are very hard to tear and break, and the asphalt and foetus he good affinity. However, the asphalt composite tire is easy to tear open, and the love of the foetus can be observed.3. Determination through physical performance test.The material with 0.8m cutting is tested according to the standard physical and mechanical properties, and the standard requirement is the qualified product.Polymer waterproof coiled material usually points: jumpers JL1 type: epdm rubber waterproof sheet material is epdm as the main materials of homogeneous waterproof sheet, is internationally recognized high-grade waterproofing material, its features are: high elasticity, good extensibility and weather resistance superior performance, is the first selection of key project materials.JL2 type: rubber (plastics) blend waterproof sheet, is made up of rubber and plastic or rubber and rubber blend of waterproof sheet, is second only to epdm waterproof sheet of waterproof material, its characteristic is flexibility, viscosity, good resistance to weather after class epdm sheet.JS2 type: homogeneous resins waterproof sheet subject to EVA material, characterized by strong water resistance, good resistance to ozone, suitable for bad environment construction, the good welding performance characteristics in underground engineering such as the subway become the preferred material.JF2 type: non-vulcanized rubber and plastic waterproof sheet material, the main material is rubber and plastic, rubber and rubber are mixed together, the pressure is only after the normal temperature park, the production efficiency is high.The performance is relatively poor.FS2 type: polyethylene polypropylene fiber coil with strong penetration resistance, high tensile strength, good low temperature flexibility, linear expansion coefficient is small, easy to adhesion, friction coefficient, good stability, non-toxic, deformation adaptable, adapt to the wide temperature range, long service life, corrosion resistance, resistance to mildew, good durability tingling and comprehensive technical performance.

When choosing to purchase, it is also necessary to pay attention to whether the product labeling content meets the standard requirements, and when signing the contract, the standard, classification and size of the product should be specified.
