Printing thickener: Nws yog ib hom thickener feem ntau siv hauv kev lag luam luam ntawv.Hauv kev luam ntawv, ob qho khoom tseem ceeb, kua nplaum thiab xim muab tshuaj, yog siv.Thiab vim hais tias nyob rau hauv siab shear, qhov sib xws yuav raug txo, yog li nws yog ib qho tsim nyog yuav tsum siv lub thickener los ua kom qhov sib xws ntawm cov ntaub ntawv luam ntawv, ces siv cov tshuab luam ntawv thickener.
Printing thickener Tuam Tshoj lub luag haujlwm tseem ceeb yog muab cov khoom zoo rheological, hloov cov kua nplaum los yog xim pleev xim rau ntawm lub vijtsam luam ntawv thiab luam ntawv rau cov ntaub, muab cov xim thiab fiber ntau, thiab xyuas kom meej cov qauv ntawm cov qauv luam ntawv.txawv.Cov qauv yog qhov tseeb, xim yog ci thiab sib xws;Thaum cov dye yog tsau, cov khoom siv tshuaj tiv thaiv thiab cov khoom seem tau yooj yim tshem tawm hauv cov txheej txheem qis, ua rau cov ntaub mos muag.Nws tuaj yeem pom tau tias lub tshuab luam ntawv thickener plays lub luag haujlwm tseem ceeb hauv kev lag luam luam ntawv.
Keeb kwm kev loj hlob:
Printing thickeners muaj keeb kwm ntev ntawm kev loj hlob.Lub slurry siv ntev dhau los yog hmoov txhuv nplej siab los yog hloov cov hmoov txhuv nplej siab.Cov thickener no yog hu ua natural thickener, tab sis cov luam ntawv thickener no muaj cov nqi siv siab, qis xim qhov tob, tsis pom kev zoo, thiab kev ua hauj lwm ceev rau kev ntxuav kuj tsis zoo, thiab kev ntxhib los mos ntawm cov ntaub yog tsis txaus siab.Tam sim no, cov hom thickeners tau maj mam tshem tawm.Nws tsuas yog nyob rau xyoo 1950 uas tib neeg tau qhia txog A-xeev pulp, uas ua rau cov tshuab luam ntawv dav siv.Lub xeev pulp thickener yog tsim los ntawm high-speed emulsification ntawm kerosene thiab dej nyob rau hauv qhov kev txiav txim ntawm emulsifier.Vim tias cov thickener no muaj ntau tshaj 50 # kerosene, thiab siv ntau npaum li cas, nws ua rau muaj kuab paug rau huab cua thiab muaj kev pheej hmoo ntawm kev tawg.Tsis tas li ntawd, qhov sib xws ntawm cov ntawv luam tawm tsis yog yooj yim los kho, thiab tsis hnov tsw ntawm kerosene yuav nyob twj ywm ntawm cov ntaub tom qab luam ntawv.Yog li cov neeg tseem tsis txaus siab rau hom luam ntawv thickener no.
Luam Ntawv Thickener
Xyoo 1970, tib neeg pib tsim thiab tsim cov khoom siv hluavtaws.Lub advent ntawm hluavtaws thickeners tau zoo heev txhawb txoj kev loj hlob ntawm printing ntau lawm thiab tsa lub tshuab luam ntawv mus rau ib tug tshiab theem.Nws daws cov teeb meem ntawm ib puag ncig muaj kuab paug thiab kev nyab xeeb.Ntxiv mus, cov hluavtaws thickener muaj qhov zoo ntawm cov nyhuv thickening zoo, kev thauj mus los yooj yim thiab khaws cia, kev npaj yooj yim, nthuav qhia meej, xim ci thiab lwm yam.
Classification ntawm printing thickener:
Muaj ntau ntau hom luam ntawv thickeners, tam sim no muab faib ua ob pawg loj: nonionic thiab anionic.Nonionic thickeners feem ntau yog polyethylene glycol ether derivatives.Xws li cov thickeners yuav tsum muaj ntau yam, tab sis cov nyhuv thickening tsis zoo, qhov sib ntxiv yog loj, thiab qee qhov nyiaj kerosene tseem xav tau.Yog li ntawd, qhov no kuj txwv nws txoj kev loj hlob ntxiv.
Lub anionic thickener yog ib tug polymer electrolyte compound, uas yog ib tug copolymer nrog lub teeb crosslinking.Nws yog tus cwj pwm los ntawm qhov tsis muaj viscosity, zoo thickening nyhuv, zoo stability, tsis tshua muaj ntxiv, zoo rheology, thiab luam ntawv nyhuv.zoo.Feem ntau yog polyacrylic compounds.Tam sim no, feem ntau polyacrylic acid compound yog anionic polymer electrolyte.Nws siv txoj kev emulsion polymerization kom zoo polymerize dej-soluble monomers rau hauv cov khoom milky.Nws yog qhov yooj yim rau kev muab tshuaj txhuam thiab kev ruaj ntseg ntawm thawj paste thiab xim muab tshuaj txhuam.Cov ntaub ntawv luam tawm yog mos rau qhov kov thiab tuaj yeem khaws cia rau lub sijhawm ntev.Qhov ntawd yog qhov peb feem ntau hais txog PTF thickener.
