Cov khoom ua kom tuabtau siv dav, thiab kev tshawb fawb txog daim ntawv thov tam sim no tau koom nrog tob hauv kev luam ntawv thiab zas xim textile, cov tshuaj pleev xim dej, tshuaj, kev ua zaub mov thiab cov khoom siv txhua hnub.
1. Luam tawm thiab zas xim ntaub
Kev luam ntawv textile thiab txheej kom tau txais cov txiaj ntsig zoo thiab zoo ntawm kev luam ntawv, feem ntau nyob ntawm kev ua tau zoo ntawm cov tshuaj nplaum luam ntawv, uas kev ua tau zoo ntawm cov tshuaj nplaum ua lub luag haujlwm tseem ceeb. Kev ntxiv cov tshuaj nplaum tuaj yeem ua rau cov khoom luam ntawv muaj xim siab, cov qauv luam ntawv meej, xim ci thiab puv, txhim kho cov khoom permeability thiab thixotropy, thiab tsim kom muaj qhov chaw khwv tau nyiaj ntau dua rau kev luam ntawv thiab zas xim. Cov tshuaj nplaum luam ntawv siv los ua cov hmoov txhuv nplej siab lossis sodium alginate. Vim tias qhov nyuaj ntawm cov tshuaj nplaum ntawm cov hmoov txhuv nplej siab thiab tus nqi siab ntawm sodium alginate, nws maj mam hloov los ntawm cov tshuaj nplaum luam ntawv thiab zas xim acrylic.
2. Xim dej
Lub luag haujlwm tseem ceeb ntawm cov xim yog kho kom zoo nkauj thiab tiv thaiv cov khoom uas tau coated. Kev ntxiv cov thickener kom tsim nyog tuaj yeem hloov pauv cov yam ntxwv ntawm cov kua ntawm lub txheej txheej, kom nws muaj thixotropy, kom muab cov txheej zoo khaws cia ruaj khov thiab cov yam ntxwv siv. Cov thickener zoo yuav tsum ua tau raws li cov kev cai hauv qab no: txhim kho qhov viscosity ntawm cov txheej thaum khaws cia, tiv thaiv kev sib cais ntawm cov txheej, txo qhov viscosity thaum pleev xim ceev ceev, txhim kho qhov viscosity ntawm cov zaj duab xis txheej tom qab pleev xim, tiv thaiv qhov tshwm sim ntawm cov dej ntws dai, thiab lwm yam. Cov thickeners ib txwm muaj feem ntau siv cov polymers uas yaj hauv dej, xws li hydroxyethyl cellulose (HEC), ib qho polymer hauv cellulose derivatives. Cov ntaub ntawv SEM qhia tau hais tias cov polymer thickener kuj tseem tuaj yeem tswj kev khaws cia ntawm cov dej thaum lub sijhawm txheej txheem ntawm cov khoom ntawv, thiab qhov muaj cov thickener tuaj yeem ua rau qhov chaw ntawm daim ntawv coated du thiab sib xws. Tshwj xeeb, cov o emulsion (HASE) thickener muaj kev tiv thaiv spattering zoo heev thiab tuaj yeem siv ua ke nrog lwm hom thickener kom txo qhov roughness ntawm daim ntawv txheej.
3: Khoom noj
Txog tam sim no, muaj ntau tshaj 40 hom tshuaj ua kom tuab hauv kev lag luam zaub mov hauv ntiaj teb, uas feem ntau yog siv los txhim kho thiab ruaj khov cov khoom lossis cov qauv ntawm cov zaub mov, ua kom cov khoom noj viscosity nce, muab cov zaub mov saj slimy, thiab ua lub luag haujlwm hauv kev ua kom tuab, ruaj khov, homogenizing, emulsifying gel, masking, kho qhov saj, txhim kho saj, thiab qab zib. Muaj ntau hom thickeners, uas tau muab faib ua cov khoom siv ntuj thiab tshuaj lom neeg. Cov thickeners ntuj feem ntau yog tau los ntawm cov nroj tsuag thiab tsiaj txhu, thiab cov tshuaj synthesis thickeners suav nrog CMC-Na, propylene glycol alginate thiab lwm yam.
4. Kev lag luam tshuaj lom neeg txhua hnub
Tam sim no, muaj ntau tshaj 200 cov khoom siv thickeners siv hauv kev lag luam tshuaj txhua hnub, feem ntau yog cov ntsev inorganic, surfactants, dej-soluble polymers thiab fatty alcohols thiab fatty acids. Hais txog cov khoom siv txhua hnub, nws yog siv rau cov kua ntxuav tais diav, uas tuaj yeem ua rau cov khoom pob tshab, ruaj khov, nplua nuj ua npuas ncauj, mos hauv tes, yooj yim yaug, thiab feem ntau siv rau hauv cov tshuaj pleev ib ce, tshuaj txhuam hniav, thiab lwm yam.
5. Lwm yam
Cov khoom ua kom tuab kuj yog cov khoom siv tseem ceeb hauv cov kua dej ua kom tawg, uas muaj feem cuam tshuam rau kev ua haujlwm ntawm cov kua dej tawg thiab kev ua tiav lossis tsis ua tiav ntawm kev tawg. Tsis tas li ntawd, cov khoom ua kom tuab kuj siv dav hauv tshuaj, ua ntawv, ua khoom siv av nplaum, ua tawv, electroplating thiab lwm yam.
