Raw lacquer yog cov kua mis dawb dawb uas ntws tawm ntawm cov tawv ntoo ntawm tsob ntoo sumac loj hlob. Nws yog lim los ntawm ib daim ntaub zoo kom tshem tawm impurities. Tom qab nws tau thov rau saum npoo ntawm ib qho khoom, cov xim hloov sai sai ntawm dawb mus rau xim liab, los ntawm liab mus rau ntshav, thiab nws tuaj yeem dhau los ua cov xim dub tawv tawv thiab ci xim tom qab ntev.
Urushiol yog cov khoom tseem ceeb ntawm cov lacquer nyoos, nrog cov ntsiab lus ntawm 30% mus rau 70%. Feem ntau hais lus, qhov siab dua cov ntsiab lus urushiol, qhov zoo ntawm cov lacquer.
National xim muaj zog adhesion, tawv xim zaj duab xis thiab zoo gloss. Nws yog resistant rau av corrosion, dej thiab roj. Qhov tsis zoo yog tias nws muaj tshuaj lom thiab yooj yim ua rau tawv nqaij ua xua. Tsis tas li ntawd, nws tsis muaj zog oxidants thiab muaj alkali tsis kam. Lub epoxy txheej muaj adhesion zoo, thiab muaj zoo adhesion rau hlau, pob zeb, ntoo, iav, thiab lwm yam.; Nws yog resistant rau alkali, roj thiab dej, thiab muaj zoo heev hluav taws xob rwb thaiv tsev zog. Tab sis cov laus kuj tsis zoo. Epoxy anti-corrosion txheej feem ntau muaj ob yam: epoxy resin thiab curing agent. Qhov xwm ntawm tus neeg sawv cev kho kuj cuam tshuam rau kev ua haujlwm ntawm cov xim pleev xim. Feem ntau siv cov tshuaj tua kab mob yog: ① Fatty amines thiab lawv cov kev hloov kho. Cov yam ntxwv yog tias nws tuaj yeem kho tau ntawm chav tsev kub, thiab qhov tsis hloov pauv fatty amine yog tshuaj lom ntau dua. ② Aromatic amines thiab lawv cov kev hloov kho. Nws yog tus cwj pwm los ntawm cov lus teb qeeb, feem ntau xav tau cua sov los kho, thiab qaug zog toxicity. ③ Polyamide cob. Nws yog tus cwj pwm los ntawm huab cua tsis zoo, tsis muaj tshuaj lom, zoo elasticity, thiab me ntsis tsis zoo corrosion kuj. ④ Phenolic resin, urea resin thiab lwm yam khoom siv hluavtaws. Cov resins thiab epoxy resins no yog cross-linked los tsim ib zaj duab xis tom qab high-temperature ci. Cov xim zaj duab xis muaj qhov zoo tshaj plaws corrosion kuj, thiab muaj cov khoom zoo thiab cov khoom zoo nkauj.
