Qhov zoo thiab qhov tsis zoo ntawm cov dej-based number case

Dej-raws li tus cwj mem, ua haujlwm raws li qhov nruab nrab luam ntawv tshiab, sawv tawm rau nws lub zog tseem ceeb hauv kev tsis suav nrog cov kuab tshuaj tsis muaj zog, txo cov emissions ntawm volatile organic tebchaw (VOCs), thiab yog li tsis muaj kev phom sij rau tus number case manufacturers lossis cov neeg ua haujlwm noj qab haus huv, concurrently. boosting tag nrho ib puag ncig zoo. Sau npe tias eco-phooj ywg tus cwj mem, nws cov txiaj ntsig ib puag ncig tseem ceeb hauv kev ua tsis zoo rau ib puag ncig, tsis muaj tshuaj lom rau tib neeg, tsis muaj hluav taws kub, thiab muaj kev nyab xeeb zoo, txo qis cov tshuaj lom ntawm cov khoom luam tawm, ua kom cov txheej txheem ntxuav ntawm cov khoom siv luam ntawv, thiab txo qis. hluav taws kub txaus ntshai txuas rau hluav taws xob zoo li qub thiab cov kuab tshuaj flammable, tsim ib qho "ntsuab" ntim cov khoom luam ntawv tiag.

Nyob rau hauv cov nqe lus ntawm cov yam ntxwv ntawm luam ntawv, dej-raws li tus cwj mem qhia tshwj xeeb kev ruaj ntseg, tsis muaj corrosiveness rau cov ntawv luam ntawv, yooj yim ntawm kev lag luam, pheej yig, muaj zog tom qab luam ntawv adhesion, dej tsis kam, thiab kev ziab ceev ceev (txog 200 meters ib feeb. ), siv tau rau hauv gravure, flexographic, thiab tshuaj ntsuam luam ntawv nrog lub peev xwm dav. Txawm hais tias qeeb qeeb ntawm cov evaporation yuav tsum tau ua kom cov cua sov kom qhuav thiab muaj peev xwm ua kom cov av noo-induced rov ntub dej, cov teeb meem no tau daws tau zoo los ntawm kev txhim kho thev naus laus zis.

Qhov sib xyaw ntawm cov kua dej raws li tus cwj pwm suav nrog cov dej hauv cov dej polymer emulsions, pigments, surfactants, dej, thiab ntxiv cov khoom ntxiv. Ntawm cov no, waterborne polymer emulsions, xws li acrylic thiab ethylbenzene derivatives, pab raws li pigment carriers, imparting adhesion, hardness, gloss, ziab tus nqi, abrasion tsis kam, thiab dej tsis kam rau tus number case, haum rau ob qho tib si tsis-absorbent thiab absorbent substrates. Pigments muaj xws li cov organic xws li phthalocyanine xiav thiab lithol liab mus rau inorganic sawv daws yuav xws li carbon dub thiab titanium dioxide. Surfactants pab txo qhov nro ntawm qhov chaw, ua kom yooj yim txawm tias tus lej faib rau ntawm lub substrate, thiab txhim kho kev ruaj ntseg.

Txawm li cas los xij, qhov tsis zoo ntawm cov dej-raws li tus cwj mem feem ntau yog tig los ntawm qis adhesion, tsawg ci, thiab lub sij hawm qhuav qeeb. Txawm li cas los xij, nrog kev tsim kho tshiab xws li kev txhim kho substrate pretreatment, txhim kho cov xim xim, thiab cov txheej txheem luam ntawv siab heev, cov kev txhawj xeeb no tau txo qis, ua rau cov kua dej raws li tus cwj pwm sib tw thiab, ntau zaus, dhau ntawm cov tshuaj hnyav-raws li tus cwj mem hauv kev siv tswv yim. Txawm hais tias dej-raws li tus number case incurs me ntsis cov nqi raw khoom, muab nws cov phooj ywg ib puag ncig thiab kev tiv thaiv kev noj qab haus huv rau cov neeg siv, cov nuj nqis ntxiv yog suav tias yog kev nqis peev uas tsim nyog.
