Silicone hollow glass sealant is now widely used as a kind of glass sealant, so why? Fully automatic sealant machine manufacturers will give you an analysis!
1. Improving the Grade of Hollow Glass
Silicone/butyl composite hollow glass double-pass seals can greatly improve the performance and service life of hollow glass and improve the grade of hollow glass because of giving full play to the advantages of these two sealants. Polysulfur/butyl combination is difficult to improve the service life of hollow glass due to its performance limitation. It can only be used in temporary buildings, low-grade buildings or indoor and environmentally sensitive occasions where the service life of hollow glass is not long required.
2. Convenient function, low construction loss and good improvement of construction environment
There are one or more two-component gluing machines on the regular or large-scale hollow glass processing line. Because silicone sealant and polysulfide can not be mixed, when replacing the type of sealant, it is necessary to clean the glue beater, which causes inconvenience in construction and increases the loss of sealant. If only silicone sealant is used, the cleaning of the glue beater can be cancelled because of the change of the sealant, thus the use is convenient and the material loss can be reduced.
The polysulfide sealant will emit an unpleasant odor of rotten eggs in the use process, which has a certain impact on human health and deteriorates the working environment. Silicone glass sealant has no obvious odor in the use process, so it can significantly improve the working environment and protect the physical and mental health of employees.
3. High cost performance and good economy
In hollow glass processing, silicone sealant and butyl rubber are used as two-way sealants, so that the effective performance of these two sealants can be brought into full play. Silicone/butyl composite hollow glass double-pass seals can be used for high, medium and low grade hollow glass, polysulfide/butyl composite hollow glass double-pass seals can only be used for medium and low grade hollow glass, and two-component silicone hollow glass sealants and two-component polysulfide hollow glass sealants are of the same or lower price, therefore. Silicone hollow glass sealant has higher cost performance than polysulfide hollow glass sealant.
Silicone insulating glass sealant and polysulfide insulating glass sealant have different density because of their different materials. The density of the former is generally about 1.44, and the density of the latter is about 1.70. When the same weight of sealant is consumed in the processing of hollow glass, the number of hollow glass produced by the former is obviously larger than that of the latter. In other words, the unit price of silicone is lower for users than polysulfide.
