Our company is mainly engaged in the recycling of various chemical raw materials, and has always been in line with the business philosophy of "sincere cooperation, trustworthiness, and commitment to environmental protection", and sincerely serves enterprises and institutions. We always adhere to the recycling method and reasonable prices with customers. Cooperation, and strive to "turn waste into treasure, environmentally friendly home, income-generating win-win"!
On the one hand, due to the growing demand for green development and ultra-low emissions in my country's steel industry, the environmental protection market has created a huge technological demand gap, which has promoted the environmental protection industry to enter a period of rapid development. Chemicalization refers to the obvious effect of additives, which should be a major development direction of additives. The use of nano-technology to manufacture additives has extraordinary effects, such as nano-silica and nano-calcium carbonate, which can strengthen and toughen epoxy resin, and is not heat resistant. When the ratio of nano-SiO2/E-44 is 3/100, the tensile strength and impact strength of the cured product are 47.1MPa and 11.8kJ/m2, respectively. Compared with no nano-SiO2, the tensile strength is 21% and the impact strength is higher. 39%. If the organic silane coupling agent containing 5% of nano-SiO2 is added, the tensile strength and impact strength after curing with MeTHPA are 50.8MPa and 19.0kJ/㎡, which are 8% and 61% higher than those without coupling agent. . Compared with no additives such as nano SiO2 and coupling agent, it is 30% and 100% respectively. Calcium sulfate whiskers and zinc oxide whiskers can also provide good reinforcement and toughening effects for epoxy resin adhesives. Nano magnesium hydroxide and nano antimony trioxide can be used as flame retardants to achieve reduction and reduction.
Door-to-door purchase of all inventory chemical raw materials: dyes, pigments, coatings, paints, resins, aluminum and silver pastes, rubber, hot melt adhesives, pressure sensitive adhesives, BYK leveling agents, defoamers, dispersants, UV photoinitiators, ultraviolet rays Absorbent, light stabilizer, polyether polyol, lithium carbonate, lithium hydroxide, vanadium oxide, plastic embossing ink, oleic acid, AEO, printing paste, zinc borate, hydroxypropyl methylcellulose, isobenzene Diphenol, hydroquinone, nonylphenol polyoxyethylene ether, polyethylene glycol, vinyl resin, flexible foam polyether, combined polyether, pressure-sensitive granule hot melt adhesive, recovery of menthol, flavor, vanillin , PVC polyvinyl chloride resin, recycled coconut oil lauric acid soap noodles, fumaric acid, chloroether resin, guaiacol, urotropine, zinc oxide, isocyanate MDI, TDI, white oil, glycerin, polyvinyl alcohol, Sodium alginate, etc., there are thousands of chemical names, as long as you deal with it, I will buy it, and it will be recycled within 24 hours.
The type and content of the third monomer in EPDM rubber have a direct effect on the vulcanization speed and the properties of the vulcanized rubber. Among them, dicyclopentadiene DCPD is used as the third monomer. Although the price is relatively low, the vulcanization speed of this EPDM rubber is slow, and it is difficult to use it with high unsaturation diene rubber; 6,10--1,5,9-undecatriene, etc. as the third monomer EPDM rubber has a fast vulcanization speed, and the former has become the main type of EPDM rubber. The content of the third monomer is expressed in terms of iodine value. The iodine value of EPDM rubber is generally 6-30, mostly around 15. When the iodine value is 6-10, the vulcanization speed is slow, and it is difficult to use it with highly unsaturated rubber; when the iodine value is 25-30, it is an ultra-high-speed vulcanization type, which can be used in combination with highly unsaturated diene rubber in any ratio. Therefore, when EPDM rubber is used in combination with other rubbers, attention should be paid to selecting suitable EPDM rubber varieties. Vitamin B2
