Nrog kev txhim kho ntawm cov neeg siv khoom nrhiav kev zoo nkauj ntawm cov khaub ncaws, qhov kev thov rau xim khaub ncaws kuj hloov pauv ntawm kev siv tau mus rau qhov tshiab
Shift. Xim hloov cov khoom siv fiber nrog kev pab los ntawm cov thev naus laus zis niaj hnub thiab tshiab, yog li ntawd cov xim lossis cov qauv ntawm cov ntaub nrog lub teeb, kub,
Cov av noo hloov pauv ntawm qhov "static" ib txwm muaj mus rau hauv qhov "dynamic" effect, hauv kev lag luam textile
Rau kev loj hlob sai thiab daim ntawv thov dav.
Cov khoom hloov ximhom thiab cov txheej txheem hloov xim *
(1) cov khoom siv photosensitive
Cov khoom siv hloov pauv photosensitive yog ib hom kev hloov pauv uas tuaj yeem tshwm sim hauv qab kev cuam tshuam ntawm ultraviolet lossis lub teeb pom kev, thiab tuaj yeem ploj mus tom qab lub teeb
Hloov mus rau cov xim qub uas ua haujlwm tau zoo. Cov ntaub ntawv hloov pauv xim uas rhiab heev yog cov nyiaj chloride, nyiaj bromide, stilbene.
Chav kawm, chav kawm nplhaib sib nqus, chav kawm nornadiene, chav kawm ntes cov anhydride uas tau ua kom zoo, derivatives triphenylmethane, chav kawm salicylic acid aniline
Cov ntsiab lus, thiab lwm yam. Tam sim no, cov khoom siv hloov xim photosensitive tau tsim kom muaj 4 xim yooj yim: ntshav, daj, xiav, liab. Plaub
Cov qauv pib ntawm txhua yam khoom siv photovarying yog hom kaw voj, uas yog, tsis muaj xim luam tawm ntawm daim ntaub, thiab tsuas yog hloov pauv hauv qab ultraviolet hluav taws xob
Xim av, daj, xiav, liab.
(2) cov khoom siv thermal rhiab heev
Qhov laj thawj yog vim li casCov ntaub ntawv hloov xim thermosensitivetuaj yeem hloov xim yog vim tias xim tuaj yeem ua rau muaj kev hloov pauv ntawm cov qauv sab hauv, ua rau muaj kev hloov pauv ntawm xim, thaum qhov kub txo qis, xim rov qab los. Piv nrog cov xim pleev xim, kev tshawb fawb txog cov xim thermal hauv tsev thiab txawv teb chaws ntau dua, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov ntawm textile luam ntawv, tau ua tiav qee qhov txiaj ntsig, ntau cov khoom luam ntawv thermal tau luam tawm.
