I. Cov ntsiab lus ntawm cov xim yas txuam:
Cov lus txhais: xim sib txuam yog xim liab, daj, xiav (peb lub ntsiab xim) ntawm lub hauv paus ntawm peb lub xim yooj yim, muaj qhov nyiam, uas yog raws li cov tseev kom muaj ntawm cov xim daim npav xim qhov sib txawv, nyob hauv kab nrog cov qhua cia siab kom tau txais xim , kev lag luam thiab hauv kev ua, siv xim.
Tsis tas li ntawd, cov xim yas tseem tuaj yeem muab cov yas ua ntau yam haujlwm, xws li txhim kho lub teeb pom kev zoo yas thiab huab cua tsis kam;
Muab cov yas tshwj xeeb qee qhov haujlwm, xws li hluav taws xob conductivity, antistatic, tua cov kab mob thiab lwm yam khoom tshwj xeeb;
Cov xim sib txawv mauv mauv zaj duab xis muaj kev ua haujlwm ntawm kev ziab lossis zam cov kab, kev yub thiab lwm yam.
Ntawd yog, los ntawm kev txuam xim tseem tuaj yeem ua tiav qee yam ntawm cov ntawv thov.
Ii. Tus tub:
Xim thiab dyes
Cov yam ntxwv xim: Cov xim muaj xim yog xim uas tsis tuaj yeem yaj ua ke nrog cov kuab tshuaj. Yog li, kom tau txais cov xim zoo nkauj, nws yog qhov tsim nyog los faib cov xim xim tusyees hauv plastics los ntawm kev siv tshuab cua sov thiab sib tov.
Cov xim xim tau muab faib ua cov organic pigments thiab inorganic xim raws lawv cov qauv.
Cov xim inorganic:
Qhov zoo: zoo thermal stability, huab cua zoo heev tsis kam, zoo heev lub teeb stability, tus nqi qis, zoo heev dispersion kev ua tau zoo.
Piv txwv li: titanium dioxide, carbon dub thiab lwm yam.
Titanium dioxide series: muaj mas peb hom titanium dioxide, zinc oxide thiab zinc barium dawb.
Titanium dioxide rutile hom thiab anatase hom ob hom kev teeb tsa, rutile hom titanium dioxide refractive index yog qhov siab, lub zog npog lub zog, ruaj khov, huab cua zoo kuj.
Yog hais tias titanium dioxide tsis tawg thaum lub qub chaw tawm ntawm lub Hoobkas, yuav muaj ntau qhov dub ntawm cov xim sib txuam hauv cov txheej txheem, uas belongs rau lub xeev kev tawg thiab tsis qhib. Yog li ntawd, cov khoom xaib yog qhov xav tau rau dispersing kev ua ntej nws yuav siv tau. Qee hom kev lag luam nkag mus tom khw tom qab kev ua, thiab cov khoom siv no tuaj yeem siv ncaj qha.
Mas siv los npog qhov transmittance ntawm cob thiab nce kom dawb.
Cov pa roj carbon dub: nws yog ib qho siv dub xim dub nrog tus nqi qis. Tsis tas li ntawd, nws muaj ultraviolet tiv thaiv (los tiv thaiv kev laus) cov nyhuv thiab hluav taws xob conductivity nyhuv ntawm plastics. Cov txheej txheem sib txawv muaj peev xwm ua tau txais ntau yam sib txawv ntawm cov pa roj carbon dub sib txawv, nrog cov khoom sib txawv heev.
Raws li kev siv cov pa roj carbon dub tau muab faib ua cov xim roj carbon dub thiab roj hmab txhawb ntxiv nrog cov pa roj carbon dub, raws li nws lub peev xwm muaj peev xwm muab faib ua cov pa roj carbon dub dub, cov xim nruab nrab hauv cov xim dub thiab cov pa roj carbon dub dub.
Cov pa roj carbon dub hais tau cuam tshuam rau kev sib sau ua ke. Txhawm rau txhawm rau txhim kho lub zog xim ntawm carbon xim dub thiab kom daws tau cov dispersion ntawm carbon dub, dispersants yuav tsum tau ntxiv rau kev ua ntej ua ntej siv.
Qhov tsis zoo: cov xim tsis zoo, qhov ntsuas kub ntawm qhov hnyav, ntau qhov ntxiv, tsis yog xim qaim;
Feem ntau siv rau hauv: siv los ua kom cov xim muaj zog (raws li cov xim xav tau feem ntau ntawm txhua yam cob tau), tshwj xeeb hauv kev tsim ua tshuab plastics muaj cov kev ua tau zoo, xws li: PA, PC, PBT, POM, PPO, PPS thiab lwm yam cov ntaub ntawv thiab cov xim tsis muaj pob tshab, cov xim txho.
