Cov khoom siv feem ntau siv rau hauv kev tsim cov ntawv tshaj tawm PP yog daim ntawv lo. Raws li kev txheej ntawm daim ntawv lo, peb hom kua dub yog tsim rau kev luam ntawv: kua dub organic solvent tsis muaj zog, kua xim, thiab kua zas xim.
Daim ntawv lo PP uas luam tawm los ntawm cov kua dub organic solvent tsis muaj zog feem ntau hu ua daim ntawv lo sab nraum zoov lossis daim ntawv lo roj uas yaj tau, thiab tuaj yeem siv sab nraum zoov yam tsis muaj zaj duab xis.
Daim ntawv lo uas luam tawm los ntawm cov kua xim kua, hu ua cov nplaum uas tsis ntub dej hauv kev lag luam muag khoom, tsis npog cov zaj duab xis thiab tsuas yog siv hauv tsev xwb.
Daim ntawv lo uas luam tawm los ntawm cov kua xim yog yaj tau hauv dej, thiab nws tsis tiv taus dej noo. Lub txheej yaj thaum nws kov dej, yog li nws yuav tsum tau npog nrog zaj duab xis hauv tsev rau kev siv. Qhov kub thiab txias ntawm daim ntawv lo yog -20 ℃ - + 80 ℃, nrog qhov kub tsawg kawg nkaus ntawm daim ntawv lo yog 7 ℃.
Hauv peb cov khoom teev npe, peb muaj ntau yam khoom siv tau ua kua cwj mem. Xws li xim liab solvent 135, xim txiv kab ntxwv 62, xim liab ncaj qha 227, kua dub 2, thiab lwm yam.
Cov kuab tshuaj liab 135yog cov roj soluble solvent dyes. Nws tuaj yeem soluble hauv cov roj tshuaj, thiab muab cov xim ci ntsa iab.
cov kuab tshuaj txiv kab ntxwv 62yog ib feem ntawm cov xim pleev xim hlau uas muaj cov kuab tshuaj. Nws tuaj yeem yaj rau hauv cov kuab tshuaj organic, xws li cawv lossis cov ntsuj plig mineral, thiab feem ntau siv rau hauv cov ntawv thov xws li cov ntawv luam tawm zoo, cov cim, thiab kev luam ntawv hauv kev lag luam.
Liab ncaj qha 227yog ib hom xim ncaj qha. Nws yog cov xim yaj hauv dej uas feem ntau siv rau kev zas xim rau cov plaub mos, cov paj rwb, thiab cov nylon fibers. Lawv kuj tseem siv tau rau hauv cov kua mem kom muab cov xim ci thiab ci ntsa iab.
Kua dub 2yog ib hom aicd dyes. Nws yog siv rau kev zas xim paj rwb thiab lwm yam cellulosic fibers. Lawv kuj tseem siv tau rau hauv cov kua mem rau kev luam ntawv ntawm cov ntaub ntawv nqus dej.
Yog tias koj tab tom nrhiav cov xim zoo siv rau cov kua mem, thov hu rau peb.
