Anti-flowing self-extinguishing polyurethane solvent-free sealant research and application

Plastic characteristics of a very dark, but also any other common types of plastic can not match. 3.2 Shear Strength of summer and Shin-Etsu product KE348, 347,3475 compare the shear strength of bonding plate experiment A1 A1 board, according to Shin-Etsu Chemical Co., Ltd. product standard port experiment. Figure curing time on the shear strength of the relationship with the experiment shows, curing the first 5 days, the shear strength increases with time, five days after a change in the basic vote, that the adhesive is curing time of 3 to 5 days , 5 days after the basic maximum strength. Tests, the gum and Shin-Etsu Chemical Industry Council of DU-type strains of sealant products KE348.347 the shear strength of the phase cicada United States, more than 3475 high cut about 3 to 4 times. 3.3 The experimental system worthy of age support 2O × 30 × 2mm chamber piece, curing for 5 days, the film will do well regardless burn into flames, leaving the flames, the observed selling self-extinguishing. 3.4 anti-possession of Li River between the two groups of anti-plastic flow of speech pterygium and curing time of asking is a contradiction, dual glue in pterygium crosslinking reaction carve the initial stage of joint of bones in the news section, termination phase (reaction listless billion), while the initial \must be linked to the intermediate stage to a long ting. Time of 15 minutes zO points 3O 5O sub irrigation sub-4o minutes long insanity O. {helmet 5cmO. 25cm. O. 2 ∞ O ・ 2 ~ mo ・ 2 ~ m with cunning for 15 minutes after the coated glass plate placed in the vertical, 15 minutes is basically the anti-flow {I6l sex, but because of their gravity and slightly drooping. 3.5 ambient temperature effect on the operation of the same two-component reactive adhesive is cunning, is exothermic, with glue directly affect the operation of the multi-step when you hear t is the total cavity volume of 1 kg to discuss environmental temperature on When you hear of. Ambient temperature (℃) for a 15-lOOlO203035 handsome group of oak time (minutes) 20015o706055503520 experiments show that the higher the temperature, the shorter the operation Q | lower the temperature, the longer the operation i and the temperature with more than 3O ℃, the reaction rate increase process fast operation, decreased smell. 3.6 Assimilation of operating ■ agent with the smell of resistance to assimilation agent rejection rate on operating when you hear a great impact, now controlled experimental conditions, La at 25 ℃, cavity volume of one kilogram, the test dosage assimilation smell of operation impact. Jing Gu assimilation capacity () 1OO80'70 operation asked (points) 40,150,210 assimilation agent proved to reduce the amount of ancient reaction rate can be reduced to extend the operation cyberspace, while experiments show that the amount of t only in the ancient assimilation agent 8O ~ 12O of smell change, change over this range, clear cavity will affect the overall performance, a small amount of assimilation of eight different mix of a rubber. 4, should be thrown in the Ministry of Communications introduces key plant of Lanzhou and foreign joint credit luxury car Vios passenger car factory TLK6701 trial, the use of research in this paper the anti-sub-flowing self-extinguishing sealed chamber body, then, revolves around the roof seam sealing performance. Resistant to rain, high and low temperature impact resistance, weatherability, boring work is simple, non-toxic, tasteless, after three years of technology to track, proved a very good operating results, the manufacturers said he fully convertible and Nissan NISSANW4O KE348 sealant used in the United States relative to daughter in law, the price only one-third of imports, and we also bring products actinides in the Pearl River Shipyard glass doors and windows sealed on boats,[link widoczny dla zalogowanych], speed boats after two years of operation, glass, plastic,[link widoczny dla zalogowanych], revolves access than the U.S. performance and resistance to water, much better weather resistance, promotion of the product can save a lot of foreign exchange for the country, for the enterprise was to create a good F by the benefits. 5, Conclusion 1, the paper flow of the study of anti-La {I6l self-extinguishing polyurethane polyurethane alcohol alcohol sealed chamber sealed chamber for China's industrialization, industrialization to a new level really laid some foundation. 2,[link widoczny dla zalogowanych], and Japan compared to the same type of seal cunning, shear strength and adhesion spider stacked high. 3, the temperature of the cavity shear strength of spider has a great influence, the lower the temperature, the higher the stack of cut spider. Low temperature resistance, and can be a long cold season in the northern region to promote. Cross-linked tough period, cut the stack at any time ask the increase of the degree, 5 days after the degree of shear stack remained unchanged. 5, when you hear the ambient temperature affect on the operation, the lower the ambient temperature, the longer the operation,[link widoczny dla zalogowanych], asked. 6, the assimilation of operations, asked dosage influential, according to experience, assimilation can only be calculated dosage of the amount of BO ~ 120 of cyberspace changes, assimilation small doses, different of a plasticine.
