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"!
⒉2 Processing performance of processing aids 2. For specific use, generally mix the sucrose ester with a small amount of water or oil, etc., and then add the required amount of water, oil, ethanol, etc., and heat appropriately to fully dissolve the sucrose ester. dispersion.
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 acetate resin, flexible foam polyether, combined polyether, pressure-sensitive granular hot melt adhesive, recycled 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 handle it, I will buy it, and it will be recycled within 24 hours.
In PP molding, fillers such as silicate, calcium carbonate, silica, cellulose, and glass fiber are filled in the polymer to achieve PP heat resistance, cost, rigidity, molding shrinkage, etc., but PP impact strength, The elongation will follow. As a kind of inorganic non-metallic whiskers with excellent performance, glass fiber has low price, good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, and is widely used. The performance of PP modified by glass fiber filling is obvious, but glass When the fiber addition amount reaches about 30%, the mechanical properties of the material can be obvious; when the addition amount is too large, part of the glass fiber will not be fully impregnated, making the bonding performance of the polymer matrix and the glass fiber interface worse, and the composite material The mechanical strength decreases, and with the flowability of the composite material with the added amount of glass fiber, the PP molding process performance is difficult.

On October 27, 2017, the list of carcinogens announced by the Research Institute of the Health Organization was initially compiled for reference. Polyols are listed in the list of 3 types of carcinogens. On May 30, 2019, a new study found that the polyol contained in ordinary glue can be used in the liquid of hematopoietic stem cells. On this basis, it is expected to significantly increase the cost of hematopoietic stem cells, help, etc., insoluble in gasoline, kerosene, vegetable oil, Benzene, toluene, carbon dioxide, ethyl acetate, methanol, ethylene glycol, etc. Slightly soluble. It is soluble in glycerol at 120～150℃. But it becomes a jelly when cooled to room temperature. To dissolve polyol, add the material to room temperature water under stirring. After the dispersion is uniform, the temperature is increased to accelerate the dissolution, which can prevent agglomeration and affect the dissolution rate. The 5% polyalcohol aqueous solution is very good for borax and boric acid, and it is easy to cause gelation. When the borax reaches 1% of the solution, it will produce irreversible gelation. Chromate, dichromate, and permanganate can also make polyol gels. The viscosity of PVA 17-88 aqueous solution gradually increases with time at room temperature. But the viscosity when the concentration is 8% is yes, and it has nothing to do with time. It is a special phenomenon c. Polyol has good film-forming properties and is highly uncomfortable for many gases except water vapor and ammonia. It has good light resistance and is not affected by light. It is ok when the fire is open, it has a special smell. When the aqueous solution is stored, it sometimes becomes toxic. , Sexless to human skin.
The company recycles thousands of chemical products. Our company promises to recycle them quickly, at a reasonable price, and with professional, safe and environmentally friendly methods. Welcome your calls and sincerely look forward to cooperating with you!
