Brief introduction of KS hot melt adhesive
In the process of PE composite geomembrane seepage prevention, it is often difficult to deal with the problem of adhesion between membrane and membrane, membrane and non-woven fabrics, non-woven fabrics and non-woven fabrics, membranes and concrete, non-woven fabrics and concrete. At present, there are some limitations in the hot welding method, which limits the application range of PE composite geomembrane. In order to ensure the integrity of the system, it is very important for the construction of the composite geomembrane and the connection quality with the building. KS adhesive for hot melt adhesive type, better make up the welding machine can not meet the requirements, it has the advantage of:
1, to solve the PE (polyethylene), EPC (ethylene propylene resin) technical problems of composite geomembrane in large area field non polar materials bonding.
2, a glue can, for the construction of composite geomembrane, film, non-woven fabrics, concrete three materials and adhesive sticking to each other.
3, for the composite geomembrane was destroyed (such as carbon, top breaking, etc.), the use of the glue can be quickly repaired and reinforced.
4, when the composite geomembrane adhesion to concrete, not only to the bonding glue, and is a waterproof layer, and the adhesive layer is membrane seepage prevention effect, improve the anti-seepage ability, rubber elongation rate is bigger, to meet the basic crack, to protect the geomembrane, so as not to pull the bad.
5, when used for bonding between non-woven fabrics, adjust the temperature of the glue, can be used less glue, adhesive, does not affect the drainage function of non-woven fabrics, non-woven fabrics can also be impermeable.
6, for the irregular structure or complex structure of composite geomembrane seepage control construction, with Ks glue can be spliced, joints will not leak.
7, when the building through the waterproof layer or waterproof layer and building connection, KS glue is a kind of ideal adhesive sealant.
8, and hot welding method complement, make up for the lack of welding method.
1 field heating melt adhesive products, the aluminium pot diameter of 20 ~ 30cm or so is appropriate, while stirring while heating. The temperature is not too high, so as not to smoke, the temperature is too high, will cause the oxidative decomposition of rubber, affecting the performance of adhesive.
2 during construction, it is best to use special tools - metal (solid glue roller, diameter should be 40mm in length, width and fixed by glue). When bonding, the roller is arranged in the rubber, and the rubber is heated to the same temperature, and the pot a slightly wider than the inclined roller board when the roller is removed from the pot, rolling on the board, the control on the roller in a contest, can guarantee the uniform coating; on the other hand, to avoid the waste of adhesive flows. The glue roller is intermittent, always placed in hot glue. Can also use wood to metal scraper coating.
3 respectively in the two bonded surface coating, should immediately make the two compression bonding, bonding surface combine closely. Winter construction, each coating length preferably not more than 40cm, fast operation. The site can be used on hammer or rubber bonding surface pressure pressure etc.. If the foundation is not flat, the joint under a wide liner about 35cm mobile wugeban. If only in a bonding surface coating, adhesive, bonding strength will be greatly reduced.
4 when the bonding between film and nonwoven fabric or non-woven fabrics and non-woven fabrics, just for the purpose of improving the strength of the joint, can glue, only in a bonded surface quickly bonded, even using the stick method. When the adhesion between film and nonwoven fabric or non-woven fabrics and non-woven fabrics, non-woven fabric requirements shall not be leakage, in the surface with a slightly higher temperature of the coating roller, the glue penetration into non-woven fabric, surface membrane, and then adhesive.
5 when the composite geomembrane and building connection, concrete (concrete) surface must be smooth and clean up, and in the concrete surface bonding, respectively.
The service life of the product is more than 50 years; the storage period is 30 years
