Xim yog ib yam khoom uas tau siv rau saum npoo ntawm ib yam khoom thiab tuaj yeem tsim cov zaj duab xis txuas ntxiv uas tau khov kho. Nws feem ntau yog tsim los ntawm roj, cob, xim, ua kom qhuav thiab lwm yam khoom siv pabcuam. Ntawm lawv, roj thiab roj hmab yog cov yeeb yaj kiab-tsim cov ntaub ntawv txheej txheej, uas yog lub hauv paus ntawm txheej txheej thiab txiav txim siab cov yam ntxwv tseem ceeb ntawm txheej txheej. Lawv raug hu ua cov yeeb yaj kiab tseem ceeb tsim cov tshuaj. Cov xim thiab cov muab tshuaj tsis tuaj yeem tsim ua zaj duab xis los ntawm lawv tus kheej. Lawv feem ntau yog siv rau xim thiab txhim kho kev ua yeeb yaj kiab xim. Lawv ua lub luag haujlwm thib ob hauv cov txheej txheej thiab raug hu ua cov yeeb yaj kiab tsim ua yeeb tshuaj theem ob. Lwm tus yog hu ua cov yeeb yaj kiab-tsim cov tshuaj, uas feem ntau txhim kho qee yam khoom ntawm txheej.
Cov xim hauv cov xim muaj lub zog zais zais. Nws tuaj yeem tsis tsuas yog npog cov xim qub ntawm cov nplaim txheej, tab sis tseem muab cov xim ci rau cov zaj duab xis txheej kom ua tiav cov txiaj ntsig ntawm kev zoo nkauj thiab kho kom zoo nkauj. Nyob rau tib lub sijhawm, cov xim thiab tus neeg sawv cev kho tau nruj ua ke thiab sib xyaw ua ke, uas tuaj yeem txhim kho lub zog ntawm lub tshuab thiab kev nplaum ntawm txheej txheej zaj duab xis, tiv thaiv kev tawg, thiab nce qhov tuab ntawm zaj duab xis txheej, tiv thaiv kev nkag mus ntawm ultraviolet rays thiab noo noo , txhim kho kev tiv thaiv kev laus ntawm zaj duab xis txheej, thiab txuas ntxiv nws lub neej siv.
Hlau oxide pigments feem ntau yog siv ua xim xim hauv kev tsim cov tshuaj pleev xim. Lawv muaj lub luag haujlwm rau xim thiab zais. Lawv yog cov yeeb yaj kiab ua yeeb yaj kiab thib ob thiab muaj qee yam cuam tshuam rau rheology, chalking tsis kam, huab cua tsis kam thiab tshuaj lom neeg tsis kam ntawm txheej. Lub luag haujlwm ntawm. Hauv kev tsim cov txheej txheej, cov hlau oxide pigments yuav tsum muaj xim dawb huv, lub zog zais zoo thiab lub zog tinting, thiab tsis hloov xim nyob rau qee lub sijhawm, uas yog, huab cua tiv taus.
Txawm hais tias tsis muaj kuab lom lossis dej-txheej txheej, yog siv cov xim hlau oxide xim, lawv lub luag haujlwm tsis yog tsuas yog npog thiab kho kom zoo nkauj, tab sis kuj tseem txhim kho lub cev thiab tshuaj lom neeg cov txheej txheej, txhim kho cov tshuaj ruaj ntseg, thiab tseem txhim kho kev zais lub zog , xim muaj zog, thiab tiv taus xeb. Kev tiv thaiv, lub teeb tsis kam, huab cua tiv taus, txhim kho lub zog siv tshuab thiab nplaum ntawm txheej zaj duab xis, tiv thaiv kev tawg, thiab nce qhov tuab ntawm zaj duab xis txheej, tiv thaiv kev nkag mus ntawm ultraviolet rays thiab noo noo, yog li ncua kev laus thiab txuas ntxiv lub neej ntawm txheej zaj duab xis
Ntawm cov xim, vim yog xim ntshiab thiab ntshiab ntawm cov hlau oxide pigments, muag muag thiab sib haum xeeb, lub zog tinting siab, nplua thiab zoo ib yam me me, nws muaj cov xim ua tau zoo. Vim tias nws tsis muaj tshuaj lom, tsis muaj ntshav, tus nqi qis, thiab tuaj yeem tsim ntau yam tones sib txawv, thiab tib neeg' nyiam thiab xav tau muag muag, nyob ntsiag to, thiab xim zoo nkauj xim zoo nkauj, nws tau siv dav nyob rau hauv coatings, xim, thiab inks. nruab nrab. Cov xim hlau oxide tau siv hauv tsev tsim sab hauv thiab sab nrauv phab ntsa, pleev xim rau xim av, pleev xim rau daim ntawv, nkoj, tsheb, tsheb, kav dej thiab kev xeb, ntoo thiab hlau rooj tog, tawv, txheej txheej, cov khoom ua si thiab cov khoom siv niaj hnub thiab lwm yam txheej.
Ntawm cov khoom lag luam txheej, txheej txheej txheej uas siv cov xim hlau oxide ntau tshaj rau ntau dua 60% ntawm tag nrho cov hlau oxide pigments siv hauv txheej, tom qab ntawd los ntawm cov chaw hauv nroog, nkoj, tsheb, kav dej, roj tso tsheb hlau luam, cov cim tsheb, guardrails. Muaj txheej txheej xws li, ntim khoom, rooj tog zaum thiab tawv suav txog li 35%, thiab tshwj xeeb txheej txheej suav txog li 5%. Cov txheej txheej tau tsim los ntawm cov txheej txheej roj rau cov txheej txheej hluavtaws. Ntau txheej txheej tsis tuaj yeem sib cais los ntawm kev thov cov xim. Tshwj xeeb, cov xim hlau oxide tau dhau los ua qhov tsis tseem ceeb xim ntau yam hauv txheej txheej txheej.
