Essentials of polysulfide sealant knowledge-polysulfide sealant manufacturers
As one of the waterproof plugging and sealing products, the importance of polysulfide sealant in the use of waterproof engineering is self-evident. Even in the entire industry, the advantages and uses of polysulfide sealants are very representative in the industry. Do you know enough about it?
Let's first take a look at what are the commonly used waterproof sealing materials jfxj01
1. Asphalt is a road caulking material used earlier. It is cheap and easy to obtain; but it has a low displacement ability, and will become soft or even flow at high temperatures, and will become brittle and lose elasticity at low temperatures, so the sealing effect Not ideal, it is only suitable for occasions where the joints have not changed much, and is currently replaced by modified asphalt;
2. Compared with asphalt, modified asphalt has improved high and low temperature resistance, but its displacement ability is still not high. It is only suitable for occasions where the joints are not changed much. However, due to its low price, it is now widely used;
3. Both polysulfide sealant and polyurethane sealant are classified as room temperature vulcanized rubber products, which can be made into products with low modulus and high displacement ability; they are now used in caulking and sealing of ordinary roads, highways, airports, etc. widely;
4. Road maintenance The joint glue is a two-component material, and the two components need to be mixed evenly and poured into the joint during construction. It has the characteristics of good oil resistance and can be used in the range of -30℃～80℃, so it can be used in occasions where the temperature is not particularly low. But its anti-UV aging function is not very good. Although the initial summary function is good, after 1-2 years, it will show cracking, hardening and other phenomena, which will make the seal ineffective and need to be repaired or re-filled;
5. Road maintenance joint sealant is also a two-component product, it has better oil resistance, high and low temperature resistance and similar to polysulfide sealant, and the application is also the same. Its anti-aging function is slightly better than that of polysulfide sealant. It can be used for 2-3 years. Generally, it must be repaired or re-filled after 3 years.
Among them, polysulfide sealant is mentioned. Are we familiar with it? Are there any requirements for the use of polysulfide sealant? Choose the correct polysulfide sealant to make the waterproofing project more perfect. For the sealant, there are the following three requirements:
â‘ It can still maintain certain elasticity and extensibility under the local lower temperature and temperature; it does not become soft under the higher local temperature and temperature. When the vehicle passes through the repaired cracks, the repaired materials cannot be swept away by the tires.
â‘¡The distribution of cracks on the original road surface should be considered. The sealant selected for pavement with severe cracks should have high viscosity and low sensitivity to road conditions; the polysulfide adhesive selected for pavement with fewer cracks should have high extensibility and cohesiveness.
â‘¢The amount of traffic on the road must be considered. When mending seams on slow lanes or sidewalks with small traffic, it is necessary to choose sealants that have stronger tire roll resistance under high temperature conditions in summer, which is more demanding than polysulfide sealants used for high-grade roads. high.
