Sealing strip construction industry development prospect of applications

Some irresponsible manufacturers only see short-term interests, started from the raw materials of unfair competition (so-called cut corners, shoddy, with waste engine oil, oil refinery remaining YouDeZi instead of high quality plasticizer etc.), for the vast number of consumers has brought a lot of hidden dangers. In production process, the door sealing strip investment accounts for a small proportion, but its role can not be ignored, doors and Windows sealing strip quality differential method includes the following: 

1. The precipitate appeared on the surface of oil leakage phenomenon, the used oil and the PVC no and dissolved, sealing strip surface is easy to appear fat, on the surface profiles are infected with yellow mark. Don't even environmental protection there are a lot of volatile matter, pollute the air. 

2. When those so-called plasticizer volatilization or leakage sealing strip will lose its original softness, become very hard, and soon aging contraction, this part of the doors and Windows closed in large aperture, got worse in sealing (water leakage, leakage of dust), in particular, the steel lining plastic door window surface will soon be corrosion, there are a lot of users are often found in the rainy season from the window inside layering parts many red liquid are dirty, the Windows and doors premature leaking steel lining corroded, doors and Windows can greatly reduce the life of a. 

In the process of practical production, sealing strip investment accounts for a small proportion of the construction industry, but its role can not be ignored. So you don't have to in order to decrease the cost of slightly better choose those fake fake products, the identification method is very simple.
