Anonymous users2024-02-05Phenolic wheels are also known as bakelite wheels or bakelite wheels, and their special materials greatly improve the performance of casters, which are beautiful and generous, impact resistant, high bearing capacity, wear resistance, certain chemical resistance, low and high temperature resistance (-45 150), protect the ground, and drive without wheel prints, which are high-grade casters. It is suitable for storage flat trucks, chemical instruments and equipment, scientific research instruments, logistics equipment, food processing machinery, packaging machinery, electrical equipment, and industrial shelves.
This type of wheel, the export volume is quite large. It has great market potential. The plywood produced with phenolic glue as an adhesive is generally used for building formwork, called cement formwork, since the eighties, the production process of domestic cement formwork has not changed much, the adhesive is the old water-soluble phenolic glue, in the mid-nineties, due to the price of raw materials used in the production of the glue, in order to reduce the production cost, melamine is added on the basis of phenolic glue, which is called modified phenolic glue, and is used in the production of cement formwork instead of phenolic glue.
At the beginning of this century, due to the rise in the price of melamine of chemical raw materials again, it turned its attention to phenolic glue with lower production cost, and transformed the production process of phenolic glue, so that its performance was improved, in order to distinguish it from the old phenolic glue, combined with its characteristics, the phenolic glue was called low-temperature curing phenolic glue.
Phenolic resin can be made into phenolic glue, phenolic fiber, anti-corrosion materials, thermal insulation materials, and compression powder. 1. Phenolic glue: mainly used in the bonding of plywood and precision casting sand mold of building materials plates. >>>More
Phenol + formaldehyde === phenolic resin (catalyst will only affect the shape of phenolic resin), phenolic resin is a polymer compound, the principle is as follows: phenol OH on phenol will affect the hydrogen on the ortho position on the benzene ring, so that the h on the ortho site becomes more active and easier to react, so the reaction is equivalent to the benzene ring is two and a half bonds, and the carbon-oxygen double bond in formaldehyde is broken at the same time, and the benzene ring is two and a half bonds combined, and there are multiple polymers of such monomers to form phenolic resin. >>>More
Activated carbon [1] Activated carbon can effectively adsorb chlorinated hydrocarbons, organophosphorus and carbamate pesticides, as well as benzyl ether, n-nitrochlorobenzene, naphthalene, ethylene, xylenol, phenol, DDT, aldrin, alkylbenzene sulfonic acid and many esters and aromatic compounds. The secondary effluent also contains organic matter that is not adsorbed by activated carbon, such as intermediate degradable substances of protein, which is more difficult to be adsorbed by activated carbon than the original organic matter, and the removal ability of activated carbon to THMS is low, only reaching 23-60%. The activated carbon adsorption method is used in combination with other treatment methods, and the ozone-activated carbon method, coagulation-adsorption activated carbon method, Habberer process, activated carbon-diatomaceous earth method, etc., make the adsorption cycle of activated carbon significantly prolonged, the dosage is reduced, and the treatment effect and scope are greatly improved. >>>More
