Kev Siv
Kev ua haujlwm ntawm cov kuab tshuaj: Cov roj hydrocarbon uas muaj ntxhiab tsw qab yog cov kuab tshuaj organic zoo uas tuaj yeem yaj ntau yam khoom siv txheej xws li cov resins thiab roj. Piv txwv li, hauv cov txheej alkyd resin, nws tuaj yeem pab cov resin kom tawg sib npaug, ua rau cov txheej kom muaj cov kua dej zoo thiab cov khoom txheej, uas yooj yim rau kev ua haujlwm tsim kho xws li txhuam thiab txau. Kev tswj hwm qhov ceev kom qhuav: Nws qhov evaporation yog qhov nruab nrab thiab tuaj yeem kho lub sijhawm ziab ntawm cov txheej. Rau qee cov txheej uas xav tau tsim ib zaj duab xis los ntawm kev ziab hauv ib lub sijhawm, cov roj hydrocarbon uas muaj ntxhiab tsw qab tuaj yeem ua kom cov txheej qhuav hauv lub sijhawm tsim nyog, yog li cov zaj duab xis txheej tuaj yeem tsim cov khoom zoo, xws li qhov nyuaj thiab ci. Hauv cov lacquers nitrocellulose, nws pab yaj nitrocellulose thiab tsim cov zaj duab xis sib xws, thiab tseem tuaj yeem tswj qhov ceev kom qhuav ntawm cov lacquer kom tsis txhob muaj cov zaj duab xis txheej tsis zoo los ntawm kev ziab sai dhau. Kev dilution number: Raws li cov kua number, cov roj hydrocarbon uas muaj ntxhiab tsw qab tuaj yeem txo qhov viscosity ntawm number, ua rau nws hloov kho zoo dua rau cov kev xav tau ntawm cov khoom siv luam ntawv. Piv txwv li, hauv cov kua luam ntawv offset, cov roj yaj uas tsim nyog tuaj yeem kho cov khoom rheological ntawm cov kua, ua rau cov kua hloov pauv tau yooj yim los ntawm lub phaj luam ntawv mus rau cov ntaub ntawv luam ntawv xws li ntawv, kom ntseeg tau tias qhov meej thiab ci ntsa iab ntawm cov xim hauv kev luam ntawv. Yaj cov resins thiab cov xim: Nws tuaj yeem yaj cov khoom siv resin hauv cov kua thiab ua rau cov xim sib kis sib npaug hauv nws. Qhov no tseem ceeb heev rau kev luam ntawv xim zoo, vim tias tsuas yog thaum cov xim sib npaug sib npaug tuaj yeem ua kom cov xim rov ua dua thiab ua tiav cov txiaj ntsig luam ntawv zoo heev.
Ntim thiab Xa Khoom
Ntim: 200kg / nruas los yog raws li cov neeg siv khoom xav tau.
Kev xa khoom: yog cov tshuaj lom neeg thiab tuaj yeem xa los ntawm tsheb ciav hlau, dej hiav txwv thiab huab cua.
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
