Elastomer-modified asphalt waterproofing membranes, plastomer-modified asphalt waterproofing membranes, asphalt composite flexible waterproofing membranes and other types of building waterproofing materials commonly used in building materials. What's the difference?

Elastomer modified asphalt waterproofing membrane is referred to as "SBS membrane", also commonly known as SBS modified asphalt waterproofing membrane. It is made of polyester felt or glass fiber felt as the children's set, styrene-butanol Diene-styrene (SBS) thermoplastic elastomer is used as a modifier and is covered on both sides with a waterproof membrane made of insulating material. Product marking is carried out according to the following procedures: elastomer modified asphalt waterproofing membrane, model, child based on surface material, thickness and standard number, for example, 3mm thick sand surface polyester tire Type I elastomer modified asphalt waterproofing membrane Material, marked SBS I PY S3 GB18242.

Plastomer modified asphalt waterproofing membrane is referred to as "APP membrane", also commonly known as APP modified asphalt waterproofing membrane. Olefin polymer APAO, APO is used as a modifier, and both sides are covered with waterproof membranes made of insulating materials. For marked products, follow the following procedures: plastomer-modified asphalt waterproofing membrane, model, according to the child's surface material, thickness and standard number, for example, 3mm thick sand-surface polyester tire type I plastomer-modified asphalt waterproofing membrane Material, APP marked me PY S3 GB18243. p> Soft tire asphalt waterproof membrane as a "compound tire membrane" is based on asphalt as the base material, composite material in two carcasses, with fine sand, mineral flakes (grains) materials called, polyester film, polyethylene The film is used as a cladding material through impregnation and rolling processing to make a waterproof membrane. Marked products should be marked according to the following procedures: product name, variety code, thickness, grade and standard number sequence marking, such as qualified 3mm thick polyethylene film covering polyester non-woven fabric - mesh composite tire flexible waterproof membrane, Marked NK-PE 3C JC/T690.

At present, some poor quality asphalt composite flexible waterproof membranes are used in tire carcass woven bag-mesh composite materials. The web layer in the carcass is cheap, mold-resistant, water-resistant, poor in durability, and easy to produce. It is characterized in that the non-woven fabric is generally made of recycled waste, high chemical composition, not impregnated, and the mesh is A clay crucible production line modified with asphalt modified out of high alkali fiberglass braid, which is usually rubber crumb. Identify these types of products by -

1. Please note that the product name and packaging identification standards, product packaging company name, product trademark, production date or batch number, production license number, storage and transportation considerations, product labels should be marked strictly The standards implemented are consistent with the product name and must not be ambiguous or improperly labeled, without production marks. When selecting these products, users must pay attention to the product's label and the identified product name, because the mark represents the identity of the product. For example, the cotton fabric-mesh composite tire production membrane has only the title Compound Tire Flexible Base Asphalt Waterproof Membrane or Composite Tire Membrane, but does not name the SBS membrane, and its product can only be called a label according to the Composite Tire Standard.

2. Identifying true and false SBS rolls from children

Generally identify the product part visually. The specific method is to tear it with hands and expose the cross-section of the tire to observe the products purchased based on optical fiber. After tearing the mesh of the composite tire If the tendons are exposed, then you can conclude that the product must be a composite fetal membrane, and what kind of composite fetal membrane needs to be exposed using a physical test - a soluble content test to observe the fetal base. Pure polyester tires, tires rolled with fiberglass polyester or fiberglass tear only the rear section is exposed.

3. Check the quality from physical testing

The appearance can only be distinguished from the fetal composite membrane or SBS, APP membrane, but it cannot be determined whether the selected product meets the quality requirements, which requires users to have the technology to inspect. Agency, soluble content according to corresponding product standards, including physical property testing plant items. The soluble content item controls the amount of asphalt and modification in the product, and can also show the true appearance of the tread base used in the product, so you can decide whether it complies with the product label
