Epoxy resin refers to an organic polymer compound containing two or more epoxy groups in its molecule. Its molecular structure is characterized by the presence of active epoxy groups in the molecular chain. The epoxy groups can be located at the end, in the middle of the molecular chain, or in a cyclic structure. Synthesis of phenolic epoxy resin: Phenolic resin is synthesized by the polycondensation of phenol or cresol with formaldehyde under acidic or alkaline conditions. Then, it reacts with epichlorohydrin under alkaline conditions to introduce epoxy groups, thereby obtaining phenolic epoxy resin.

The Nitrocellulose manufacturing process technology is based on the technology that imported from the Soviet Union in China's First Five-year Plan. It has formed a completely independent, mature and complete technical system after more than 50 years' continuous improvement and innovation. It is the most advanced industrial technology which uses cotton as raw materials in Nitrocellulose formula. Features of Nitrocellulose Plant High product quality High product quantity Low consumption of materials and energy Advanced level in the global industry SL Tec has rich experience in offering high efficient Nitrocellulose manufacturing process or updating Nitrocellulose formula for Nitrocellulose plant construction. Welcome to consult us for more details of the Nitrocellulose production process.

Acetate as green solvents are widely used in all fields. Our company adopts continuous esterification process to synthesize the corresponding acetate. Ethyl acetate and propyl acetate can be efficiently converted. The flexible production of different acetate products is realized in the same set according to the market situation. In this way, investment is reduced and anti market risk capability is increased. Acetate series technology Acetates include ethyl acetate, acetaldehyde reduction, butyl acetate, amyl acetate and etc. As environmentally friendly solvent, they are widely used in areas such as solvents, monomers, plasticizer, surfactants and polymers. The following introduction is the production process of various acetate:

There are two prevailing processes for sec-butyl acetate (SBA) production, i.e. iso-butanol-acetic acid esterification process and n-butene -- acetic acid addition process. Due to its much lower production cost, new SBA plants usually use the Addition Process, which is the very technology SL TECH provides. It consists of four units, feedstock purification unit, esterification unit, product separation unit and acetic acid recovery unit. Compared to the Esterification Process, the Addition Process for SBA production has advantages such as shorter process flow, less equipment and lower production cost (50-60% of Esterification Process); lower energy consumption (only 5% of Esterification Process); easy operation, lower maintenance cost and lower operation cost; harmless and poisonless solid acid catalyst, less pollution, less equipment corrosion.
