Himic anhydride which use to have?

Share |

Himic anhydride is white or hardly chicken clear or powder. Acrid in acetone, ethanol, toluene, ethyl acetate, chloroform, hardly acrid in petroleum ether. Calefaction of sublimation, condensate sex.

 

Himic anhydride acclimated for unsaturated polyester resin, than with phthalic anhydride, tetrahydrophthalic anhydride do adhering has bigger air drying, college calefaction resistance, smoothness, bigger electrical performance, bane attrition and automated strength. Abating abettor for adhering resins, acceptable for casting, laminated, crumb molding, solidifying actual has accomplished weatherability, calefaction attrition and dielectric backdrop of. Acclimated in alkyd resins, urea-formaldehyde resin.

 

Himic anhydride acclimated as top temperature aggressive adhering adhesive adhering abating agent, advertence dosage 80~ 90, with 90 copies is preferred, abating altitude of 120 ℃ /2h+150 ℃/5h or 80℃ /3h+120℃ /3h+200 ℃/4h. Solidifying actual has accomplished calefaction resistance, acclimate attrition and electrical properties, calefaction attrition to 200℃. In 180 ℃aging 1000h, abating acknowledgment calefaction accident is alone 1%. Hardened bottle acclimated as abating agent, abatement abettor for rubber, plastic, wire, the intermediates of enamel, resin, surfactant, pesticides, top baking point solvent. Acclimated for unsaturated polyester resin, than with phthalic anhydride, tetrahydrophthalic anhydride do adhering has bigger air drying, college calefaction resistance, smoothness, bigger electrical performance, bane attrition and automated strength. Abating abettor for adhering resins, acceptable for casting, laminated, crumb molding, solidifying actual has accomplished weatherability, calefaction attrition and dielectric backdrop of. Acclimated in alkyd resins, urea-formaldehyde resin, melamine adhering as modifying agent. Acclimated in insecticides, abating agent, plasticizer, apparent alive agent, biting agent, bolt finishing.
