Cov kua mem yog ib qho tseem ceeb hauv ntau yam txheej txheem luam ntawv, thiab ntau hom kua mem siv los ua kom tiav cov teebmeem tshwj xeeb. Cov kua mem eco-solvent, cov kua mem solvent, thiab cov kua mem dej yog peb hom kua mem uas siv ntau, txhua hom muaj lawv tus kheej cov yam ntxwv thiab kev siv. Cia peb tshawb nrhiav qhov txawv ntawm lawv.
Cov kua mem uas muaj dej yog ib qho kev xaiv uas muaj ntau thiab tsis ua rau ib puag ncig puas tsuaj. Nws muaj cov xim lossis cov xim uas yaj hauv dej. Hom kua mem no tsis muaj tshuaj lom thiab muaj VOC (cov organic compounds uas tsis yaj tau), ua rau nws muaj kev nyab xeeb rau kev siv hauv tsev. Cov kua mem uas muaj dej feem ntau yog siv rau hauv kev luam ntawv hauv chaw ua haujlwm, kev luam ntawv kos duab zoo nkauj, kev luam ntawv ntaub thiab lwm yam kev siv.
Cov kua xim uas yaj hauv cov organic sib xyaws lossis cov roj av, ntawm qhov tod tes, muaj cov xim lossis cov xim zas uas yaj hauv cov organic sib xyaws lossis cov roj av petrochemicals. Cov kua xim no ruaj khov heev thiab muab kev nplaum zoo rau ntau yam khoom siv xws li vinyl, yas thiab hlau. Cov kua xim uas yaj hauv cov roj feem ntau siv rau hauv cov paib sab nraum zoov thiab cov ntawv thov qhwv tsheb vim nws tiv taus huab cua hnyav thiab muab cov txiaj ntsig luam ntawv ntev.
Cov kua xim Eco-solvent yog ib hom kua xim tshiab uas muaj cov yam ntxwv ntawm cov kua xim uas yog dej thiab cov kua xim uas yog cov kuab tshuaj. Nws muaj cov xim uas nyob hauv cov kua xim uas tsis ua rau ib puag ncig puas tsuaj, uas muaj cov VOCs tsawg dua li cov kua xim ib txwm muaj. Cov kua xim Eco-solvent muaj kev ruaj khov dua thiab kev ua haujlwm sab nraum zoov thaum tsis ua rau ib puag ncig puas tsuaj ntau dua. Nws feem ntau siv rau hauv cov ntawv thov xws li kev luam ntawv banner, cov duab vinyl, thiab cov ntawv nplaum phab ntsa.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm cov hom kua no yog cov txheej txheem kho. Cov kua dej ua kom qhuav los ntawm kev ua pa, thaum cov kua solvent thiab eco-solvent xav tau lub sijhawm ziab nrog kev pab los ntawm cua sov lossis cua ncig. Qhov sib txawv ntawm cov txheej txheem kho no cuam tshuam rau qhov ceev ntawm kev luam ntawv thiab kev txawj ntse ntawm cov khoom siv luam ntawv.
Tsis tas li ntawd xwb, kev xaiv cov kua mem nyob ntawm seb yuav tsum tau siv li cas rau qhov project luam ntawv. Tej yam xws li kev sib haum xeeb ntawm qhov chaw, kev ua haujlwm sab nraum zoov, xim ci ntsa iab thiab kev cuam tshuam rau ib puag ncig yog ib qho tseem ceeb hauv kev xaiv hom kua mem kom raug.
Zuag qhia tag nrho, cov kua mem dej zoo heev rau kev luam ntawv hauv tsev uas tsis ua rau ib puag ncig puas tsuaj, thaum cov kua mem uas yaj tau muaj zog rau kev siv sab nraum zoov. Cov kua mem uas yaj tau muaj zog sib npaug ntawm kev ruaj khov thiab kev txhawj xeeb txog ib puag ncig. Kev nkag siab txog qhov sib txawv ntawm cov hom kua mem no tso cai rau cov tshuab luam ntawv xaiv cov kev xaiv raws li lawv cov kev xav tau luam ntawv thiab kev cog lus rau ib puag ncig.
