  • Patent number: 11293423
    Abstract: A compressor includes a housing, and an anticorrosive coating covering a surface of the housing. The anticorrosive coating includes a base layer applied on the surface of the housing, and a surface layer applied on the base layer. Both the base layer and the surface layer are organic coatings. Thus, the housing of the compressor is effectively separated from the external environment by means of the two organic coatings, so as to ensure that the compressor is not corroded; moreover, the anticorrosive coating does not contain a metal coating, thereby preventing the problem of the compressor being severely corroded due to an exposed metal coating.

  • Patent number: 11236443
    Abstract: A fiber formed from a thermoplastic composition that contains a thermoplastic starch and an aliphatic-aromatic copolyester is provided. The copolyester enhances the strength of the starch-containing fibers and facilitates the ability of the starch to be melt processed. Due to its relatively low melting point, the copolyester may also be extruded with the thermoplastic starch at a temperature low enough to avoid substantial removal of the moisture in the starch. Furthermore, the copolyester is also modified with an alcohol to contain one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the conditions of the alcoholysis reaction (e.g., alcohol and copolymer concentrations, temperature, etc.), the resulting modified aliphatic-aromatic copolyester may have a relatively low molecular weight.

  • Patent number: 9896539
    Abstract: A method for synthesizing poly(butylene adipate-co-terephthalate) by combination of melt and solid state polycondensation using an organic guanidine as a main catalyst. The ternary catalyst system includes a main catalyst, a first cocatalyst, and a second cocatalyst. The main catalyst is organic guanidine; the first cocatalyst is titanate ester or zirconate ester; and the second cocatalyst is metallic oxide. The method includes: 1) adding 1,4-butanediol (BDO), adipic acid (AA), terephthalic acid (TA), and a ternary catalyst system to a reaction still; conducting an oligo-polycondensation to yield a oligomer having the weight average molecular weight (Mw) of between 3.0×103 and 4.0×103; allowing the oligomer to perform a melt polycondensation (MP) to yield a prepolymer with medium Mw of between 1.5×104 and 3.0×104; and 2) crushing the solid prepolymer into granules of 30-40 meshes, and then allowing the granules to undergo solid state polycondensation to yield the final PBAT product.
