Physical Property

1. Exposed to sunshine: UV rays resistance, long service life and aging resistance

2. Easy installation and dimensional stability: can be wieldable under wide range of temperature and experience minus dimensional change in thermal treatment

3. High tensile strength and elongation thus can accommodate movements of substrates
4.Good flexibility under low temperature, good adaptability to ambient temperature difference
5, Secure anti-puncture and good rooting resistance, no pollution caused to environment when being welded and good    waterproofing choice for plant roofs 
6. Good plasticity: convenient and fast treatment of detailed parts of corners and edges

 

 Product usage

 Different kinds of Pvc waterproof membrane can variously be used to the roof  building, underground building,tunnel,dam,pool,sewage treatment works,garbage disposal facilities.It also can be suitable to any requirement of all kinds of technological practice&different grade of roof waterproof and underground constructions waterproof.

Q:Construction Measures for Waterproof Coil in Winter
High polymer modified asphalt waterproofing membrane to hot melt construction is more simple, the construction temperature can be within -10 ℃. 1. Base treatment agent to be volatile completely, full. Winter construction often use solvent-based treatment agent, one is free from frozen, the second is easy to operate. Low temperature in winter, solvent evaporation slow, so should strictly control the solvent drying time, winter in 10h above the basic volatile full, finished, and then arrange the hot melt coil process to prevent the fire.
Q:What is the difference between SBS and APP rolls?
Compared to the use of SBS waterproofing membrane to use a larger range. But each has its own advantages and disadvantages, according to the local environment and the actual situation of the building in combination with the characteristics of two kinds of coil to choose materials. You have to compare the next, I can only tell you SBS waterproofing membrane prices than APP waterproofing membrane high.
Q:Polyethylene polypropylene waterproofing membrane forming. Secondary molding, what does it mean? How to distinguish?
In the appearance and mechanical analysis, these two processes is difficult to distinguish, a composite also has poor quality, the second compound can also be done better. So, only in the approval of the production line, to control.
Q:What should the attention of the membrane waterproof construction?
(1) grass-roots coating on the base layer of treatment agent, requiring thin and uniform, generally dry, when the sticky hand can be paving the membrane;
Q:The difference between high polymer modified asphalt waterproofing membrane and sbs
High-polymer modified asphalt waterproofing membrane: synthetic polymer modified asphalt coating layer, fiber fabric or fiber mat for the carcass, powder, granular, sheet or film material made of cladding material can be curled Of the sheet material. Thickness is generally 3mm, 4mm, 5mm, asphalt as the main body.
Q:DTM.E polyester composite waterproofing membrane, cheaper than the asphalt membrane?
the product in line with GB18173-2006 "polymer waterproof material" national standards.
Q:Elastomer modified asphalt waterproofing membrane for what purpose? Need to pay attention to a few things?
First, the quality of waterproof base surface Waterproof base (leveling layer) must be hard, smooth, dry, clean, should not have anti-sand, remove the sharp objects. Waterproof base surface if there are defects, should be done before the waterproof repair, must be painted base treatment agent. Waterproof surface should not have ice, snow or water.
Q:Polyurethane and SBS membrane waterproof
 Methyl methacrylate (methyl acrylate), acrylamide (acrylic), polyurethane (cyanide) as the base material of the grouting material can be used for underground engineering plugging waterproof.  Because plastic in the sun is easy to aging, so used in underground engineering, and polyurethane can be made of liquid, used to plug the water.
Q:SBs waterproof cold sticky how to do?
4, paving sheet waterproof layer. Cold sticky construction of the joints is a weak part of the joints, in order to ensure the quality of seams waterproofing, each piece of the film should be posted when the standard line, that is, paving the first piece of paper before the grass, playing a good standard line, Along the shop paving, continue to pave the way, in the already prepared on the roll of the required width of the overlap and then play a good line, as a continuation of the standard line of sheet. Paving when asked adhesive or asphalt glue brush evenly, do not reveal the end, not accumulation, and need to be part of the solvent before they can roll pressure exhaust. Lap seam after the seam overflow overflow adhesive, should be flattened seal. At low temperatures, it is advisable to use hot air heating measures.
Q:Is the foundation pit waterproofing and the foundation pouring on the working face?
2, your construction process is not clear: I tell you listen to the basic cushion after the completion of the construction, the cushion surface dryness to reach more than 90% can be done when the membrane waterproof layer, waterproofing membrane construction is completed, then do C20 40 ~ 50mm fine stone concrete protective layer, the construction is completed, generally the next day can be tied in the above bar.
