  • Publication number: 20220144732
    Abstract: The solid composite stabilizer for PCE includes the following components in parts by weight: 10 to 30 parts of a phenol-substituted ion-exchange resin, 50 to 80 parts of a basic anion-exchange resin, and 50 to 100 parts of a desiccating agent. The phenol-substituted ion-exchange resin is chloromethylated macroporous polystyrene-divinylbenzene (PS-DVB) substituted by a phenolic compound; and the basic anion-exchange resin is chloromethylated macroporous PS-DVB substituted by an amine compound. The preparation method includes the following step: thoroughly mixing the phenol-substituted ion-exchange resin, the basic anion-exchange resin, and the desiccating agent in a specified ratio to obtain the solid composite stabilizer for PCE. The solid composite stabilizer for PCE is packaged in a glass fiber bag and placed in PCE for storage and use.

  • Publication number: 20210214475
    Abstract: A preparation method of PVA fiber comprises the following steps: preparing a spinning dope; PVAc is used as a raw material, and dissolved with addition of methanol before filtration, and then the spinning dope is obtained; spinning; the spinning dope is injected into a spinneret, and the ejected fibers are brought into a direct current electrolytic cell, and undergo a series of reactions of alcoholysis, electrolytic catalytic alcoholysis, and the levering of the alcohol; and the solution formulation in the electrolytic coagulation bath comprises alkali, alcohol and water; acid bath; through stretching, drying, washing with water, crimping with hot water and packaging, a finished polyvinyl alcohol fiber product is formed. The mirabilite is not needed in the coagulation bath, and PVA is obtained by the alcoholysis of PVAc in an electrolytic cell, and the produced PVA fibers present high purity and few impurities.

  • Publication number: 20210212863
    Abstract: The invention discloses a micro-negative pressure foam dressing and a manufacturing method thereof, the dressing comprises a exothermic agent layer, an isolation component covering on the exothermic agent layer, an elastic memory piece disposed under the exothermic agent layer, a liquid absorbing negative pressure pad disposed under the elastic memory piece, a contact layer disposed under the liquid absorbing negative pressure pad, a sealing film disposed between the liquid absorbing negative pressure pad and the contact layer, and a bottom release film disposed under the contact layer; and in this invention, heat generated by a exothermic agent layer causes an elastic memory piece to expand downward to compress a foam layer, and after the heat dissipates completely, a micro-negative pressure is generated since a sealed environment is formed by a sealing film, a contact layer and a wound surface without a need for the VSD negative pressure technology, which is simple to operate, simple in structure, low in co

  • Patent number: 10794421
    Abstract: An apparatus for preloading a bearing assembly on a shaft includes a first annular threaded member positioned about the shaft and a second annular threaded member positioned about the shaft. The first and second threaded members have intermeshing threads such that rotation of the second threaded member causes axial translation of the first threaded member to apply a first axial force to the bearing assembly to preload the bearing assembly. An actuator is operable to rotate the second threaded member relative to the first threaded member to apply the first axial force to the bearing assembly.

  • Publication number: 20190072129
    Abstract: An apparatus (10) for preloading a bearing assembly (14) on a shaft (12) includes a first annular threaded member (56) positioned about the shaft (12) and a second annular threaded member (68) positioned about the shaft (12). The first and second threaded members (56,68) have intermeshing threads such that rotation of the second threaded member (68) causes axial translation of the first threaded member (56) to apply a first axial force to the bearing assembly (14) to preload the bearing assembly (14). An actuator is operable to rotate the second threaded member (68) relative to the first threaded member (56) to apply the first axial force to the bearing assembly (14).
