Kev siv
Cov kuab tshuaj ua: lub teeb muaj ntxhiab hydrocarbon cov kuab tshuaj zoo uas tuaj yeem zom cov txheej txheej ntau xws li cov resins thiab roj. Piv txwv li, hauv Alkyd Resin Txheej, nws tuaj yeem pab cov khoom siv kom tawg thiab cov khoom tsim kom zoo, uas yooj yim rau kev tsim kho zoo li txhuam hniav thiab txau. Kev tswj kom qhuav nrawm: nws cov evaporation yog ib nrab thiab tuaj yeem hloov kho lub sijhawm kom qhuav ntawm cov txheej txheem. Rau qee lub tsho muaj xim uas yuav tsum tau ua ib zaj duab xis los ntawm kev ziab hauv lub sijhawm, kom cov txheej xim ua kom zoo nyob rau hauv lub sijhawm zoo, yog li ntawd cov khoom siv xim zoo hauv lub cev muaj zog, xws li hardness thiab glossiness. Hauv nitrocellulose lacquers, nws pab yaj nitrocellulose thiab ua ib qho kev ziab khaub ncaws tsis zoo ntawm lub lacquer kom tsis txhob muaj cov yeeb yaj kiab qub kom sai. Ink dilution: Raws li tus kua mem kua ntxhiab hydrocarbon kuab tshuaj pleev roj, ua rau nws zoo dua yoog raws li cov khoom siv luam ntawv. Piv txwv li, hauv kev luam ntawv offeks tuaj yeem kho cov khoom siv hluav taws xob ntawm lub num luam tawm los ntawm cov ntawv luam tawm los ntawm cov ntawv sau, kom pom kev meej thiab cov xim hauv luam ntawv. Dissolving resins thiab cov pigments: nws tuaj yeem yaj cov khoom qab zib hauv number case thiab ua kom cov pigments disperse ensusly hauv nws. Qhov no yog qhov tshwj xeeb tshaj yog rau cov luam ntawv zoo, vim tias tsuas yog faib cov khoom cuav thiab tuaj yeem ua tiav cov txiaj ntsig zoo.
Ntim thiab Thauj Khoom
Cov: 200kg / nruas lossis raws li cov neeg siv khoom.
Cov zaub mov xa tuaj: belongs rau cov tshuaj lom neeg thiab tuaj yeem xa los ntawm tsheb ciav hlau, dej hiav txwv thiab huab cua.
Khaws thiab Cia
Txee lub neej: 24 lub hlis txij hnub ua lag luam hauv cov khoom ntim tsis tau ntim rau hauv qhov chaw txias txias tawm ntawm lub hnub ncaj qha, dej.
Qhov chaw ua kom lub tsev rau khoom, tsis muaj kub kom qhuav ziab, sib cais los ntawm oxidants, acids.
