Thickenerstau siv dav, thiab cov ntawv thov kev tshawb fawb tam sim no tau koom nrog kev luam ntawv thiab dyeing textile, dej-raws li txheej, tshuaj, kev ua zaub mov thiab khoom siv txhua hnub.
1. Printing thiab dyeing textile
Textile thiab txheej luam ntawv kom tau txais cov txiaj ntsig zoo thiab kev ua haujlwm zoo, rau qhov loj yog nyob ntawm qhov kev ua tau zoo ntawm kev luam ntawv paste, uas qhov kev ua tau zoo ntawm thickener plays lub luag haujlwm tseem ceeb. Qhov sib ntxiv ntawm cov thickening tus neeg sawv cev tuaj yeem ua rau cov khoom luam ntawv muab cov xim siab, cov qauv luam ntawv yog qhov tseeb, cov xim yog ci thiab tag nrho, txhim kho cov khoom permeability thiab thixotropy, thiab tsim kom muaj txiaj ntsig ntau dua qhov chaw luam ntawv thiab dyeing lag luam. Tus neeg sawv cev thickening ntawm luam ntawv paste siv los ua cov hmoov txhuv nplej siab los yog sodium alginate. Vim yog qhov nyuaj ntawm cov hmoov txhuv nplej siab thiab cov nqi siab ntawm sodium alginate, nws maj mam hloov los ntawm acrylic printing thiab dyeing thickening tus neeg saib xyuas.
2. Cov xim pleev xim rau dej
Lub luag haujlwm tseem ceeb ntawm cov xim yog kho kom zoo nkauj thiab tiv thaiv cov khoom coated. Kev tsim nyog ntxiv ntawm cov thickener tuaj yeem hloov tau cov kua dej ntawm cov txheej txheem txheej txheem, kom nws muaj thixotropy, thiaj li muab cov txheej txheem zoo cia ruaj khov thiab daim ntawv thov zog. Lub thickener zoo yuav tsum ua tau raws li cov cai hauv qab no: txhim kho cov viscosity ntawm txheej thaum khaws cia, inhibit qhov sib cais ntawm txheej, txo cov viscosity thaum lub sij hawm siab ceev painting, txhim kho cov viscosity ntawm txheej txheej tom qab pleev xim, tiv thaiv qhov tshwm sim ntawm ntws dai. phenomenon, thiab lwm yam. Cov tshuaj thickeners feem ntau siv dej-soluble polymers, xws li hydroxyethyl cellulose (HEC), ib tug polymer nyob rau hauv cellulose derivatives. SEM cov ntaub ntawv qhia tau hais tias cov polymer thickener kuj tseem tuaj yeem tswj cov dej tuav thaum lub sij hawm txheej txheej ntawm cov khoom ntawv, thiab muaj cov thickener tuaj yeem ua rau saum npoo ntawm daim ntawv coated du thiab zoo ib yam. Tshwj xeeb, qhov o emulsion (HASE) thickener muaj qhov ua tau zoo heev thiab tuaj yeem siv ua ke nrog lwm hom thickener kom txo tau qhov roughness ntawm daim ntawv txheej.
3: Zaub mov
Txog tam sim no, muaj ntau tshaj li 40 hom khoom noj khoom haus thickening agents siv nyob rau hauv cov khoom noj khoom haus kev lag luam nyob rau hauv lub ntiaj teb no, uas yog tsuas yog siv los txhim kho thiab stabilize lub cev los yog cov ntaub ntawv ntawm cov zaub mov, ua rau kom cov viscosity ntawm cov zaub mov, muab zaub mov slimy saj, thiab ua lub luag haujlwm hauv thickening, stabilizing, homogenizing, emulsifying gel, masking, kho saj, txhim khu tsw, thiab qab zib. Muaj ntau ntau hom thickeners, uas tau muab faib ua tej yam ntuj tso thiab tshuaj synthesis. Natural thickeners feem ntau tau txais los ntawm cov nroj tsuag thiab tsiaj txhu, thiab tshuaj synthesis thickeners xws li CMC-Na, propylene glycol alginate thiab lwm yam.
4. Kev lag luam tshuaj txhua hnub
Tam sim no, muaj ntau tshaj 200 thickeners siv nyob rau hauv kev lag luam tshuaj niaj hnub, feem ntau inorganic ntsev, surfactants, dej-soluble polymers thiab fatty alcohols thiab fatty acids. Nyob rau hauv cov nqe lus ntawm cov khoom siv niaj hnub, nws yog siv rau cov tshuaj ntxuav tais diav, uas tuaj yeem ua rau cov khoom pob tshab, ruaj khov, nplua nuj ua npuas ncauj, muag muag ntawm tes, yooj yim los ntxuav, thiab feem ntau siv hauv tshuaj pleev ib ce, tshuaj txhuam hniav, thiab lwm yam.
5. Lwm yam
Thickener kuj yog lub ntsiab additive nyob rau hauv dej-raws li fracturing kua, uas muaj feem xyuam rau kev ua tau zoo ntawm fracturing kua thiab kev vam meej los yog tsis ua hauj lwm ntawm fracturing. Tsis tas li ntawd, cov thickeners kuj tau siv dav hauv tshuaj, ntawv ua, ceramics, tawv ua, electroplating thiab lwm yam.
