Hollow glass butyl rubber is a single component, solvent-free, non fogging, non vulcanizing, and plastic first layer sealant for hollow glass based on polyisobutene rubber. Hot melt butyl sealant maintains its plasticity and sealing properties over a wide temperature range, without cracking or hardening on the surface. Due to its water vapor permeability, it can form an excellent moisture resistant system together with elastic sealants. Features: Good sealing effect, easy to ensure quality; No need for curing period, saving floor space and reducing production costs; Belonging to environmentally friendly products, it is used without waste and has a clean environment.

Hollow glass butyl adhesive is a necessary adhesive for making the first seal of hollow glass using two-component polyurethane sealant, two-component polysulfide sealant, two-component silicone sealant, and hollow glass hot melt adhesive. Select different specifications of insulating glass butyl rubber according to the size of the rubber chamber of the insulating glass butyl rubber coating machine. When using butyl rubber to make insulating glass, attention should be paid to:

1. Clean the aluminum partition strip of the insulated glass and set it aside.

2. Preheat the butyl hot melt sealant into the extruder cylinder to 130-140 ℃, keep the temperature controller at a constant temperature, and then take out the adhesive strip to check for uniformity without interruption. Apply the adhesive strip to the aluminum partition groove of the insulating glass, let it cool slightly, and press it with clean glass to form the semi-finished insulating glass product.

3. After applying the outer sealant and curing, it is the finished product of insulated glass.

4. When using an imported rapid gluing machine for production, the temperature of the glue cylinder should be increased by 10-15 ℃, and the extrusion pressure should be adjusted from 150Mpa to 170-200Mpa to achieve uniform gluing.

Attention: When using butyl hot melt sealant, hands should be clean, and the surface of the sealant should not be contaminated with dust, oil, and solvents (such as gasoline, etc.). When applying the sealant, gloves that do not shed hair can be worn. Be careful not to burn yourself when coming into contact with hot glue. Gloves that come into contact with glue should be clean and free of burrs or other contaminants that can easily stick to the glue. When applying butyl hot melt sealant, the temperature should be controlled below 160 ℃, and it is strictly prohibited to apply it above 170 ℃ to avoid aging and decomposition of the adhesive.

In the first year of the 12th Five Year Plan, the expansion momentum of China's synthetic rubber industry remains strong, with a continuous increase in the number of enterprises and a rapid expansion of production scale, which further exacerbates the pressure of overcapacity. This is the information learned by the reporter from the 6th Second Council and 20th Industry Annual Meeting of China Synthetic Rubber Industry Association held in Xi'an on November 8-9.

According to Hu Jie, Executive Vice Chairman of the China Synthetic Rubber Industry Association, China's synthetic rubber industry, after ranking first in consumption in 2003 and first in production in 2009, is expected to leap to a higher production capacity this year. By the end of this year, the total capacity of China's major synthetic rubber plants is expected to reach 3.33 million tons, of which 520000 tons will be added this year, an increase of 18.5% compared to 2010. It is expected that the total production of synthetic rubber for the whole year will exceed 2.7 million tons, a year-on-year increase of 12%.

According to the current development trend, the association predicts that by the end of the 12th Five Year Plan, the annual production capacity of synthetic rubber plants in China will approach 6 million tons. Assuming the import volume remains unchanged, the overall utilization rate of the device will only be 63%; Assuming 50% of the import volume is replaced by domestic products, the overall utilization rate of the equipment will only be 74%.

Qi Runtong, Secretary General of the Synthetic Rubber Association, pointed out that in the future, synthetic rubber enterprises will face fierce market competition, and there will be a significant shortage in the supply of raw materials for synthetic rubber production, such as butadiene and isoprene. Therefore, Qi Runtong stated that curbing overcapacity is the primary task that the synthetic rubber industry needs to address.
