 Why summer some neutral glue will appear after playing in the concrete and metal window frames binding sites curing many large plate glass bubble gum, and some they will not? Is not a quality problem? Why did not previously have a similar phenomenon? A: Many brands have had similar neutral glue phenomenon, after careful testing and repeated experiments confirm the quality is not gum problems. Because alcohol-based adhesive has a neutral and two oxime, an alcohol-based adhesive and the methanol contained in the curing process releases gas (volatile methanol began at about 50 ℃), especially in direct sunlight or high temperatures encountered in the reaction more strongly . Another concrete and metal window frames are difficult breathable, with summer temperature and humidity are high, curing will be faster, gas release can only glue never fully cured layer of ran out, the cured strips sizes of bubbles will appear. The neutral oxime glue curing process does not release gases, it will not produce bubbles. But the disadvantage oxime-type glue that once the technology is neutral, recipes handled properly, cold winter will have the opportunity during the curing contraction cracking phenomenon, good technology to use large plate glass, plastic, recipes clearance would not have this phenomenon appears. Of course, oxime-type rubber price is slightly more expensive than neutral alcohol type. In the past did not appear similar phenomenon is because in the past the construction unit in such a place with a little silicone rubber, generally tend to use a waterproof acrylic sealant, so neutral silicone rubber foaming phenomenon is not very common; recent years to the increasingly widespread use of silicone sealants, which greatly improves the quality of the project grade, but because of the material properties do not understand that in the selection of improper sealant blistering. Special study of the project feasibility study report for the first exclusive commercial consultants to conduct a feasibility study for the industry investment advisory services project report large plate glass, plastic performance, this report customization services reported large plate glass, plastic prices, we will be based on different types of projects in different sectors and specific requirements, the revised report outline, and on the basis of this directory redefine the industry data and analysis of content, for the enterprise project approval, land grants, business registration, financial applications and financial advisory services to provide full guidance .
