Latex xim yog ib qho ntawm cov xim uas siv ntau tshaj plaws niaj hnub no vim nws qhov yooj yim ntawm kev siv, durability, thiab tsawg toxicity.Nws yog tsim los ntawm ntau yam khoom xyaw, nrog rau cov pigments, resins, additives thiab cov kuab tshuaj.Ib qho tseem ceeb muaj nyob rau hauv cov xim latex yog hydroxyethyl cellulose (HEC).HEC yog cov thickener thiab stabilizer uas txhim khu kev ua haujlwm ntawm cov xim latex hauv ntau txoj kev.Hauv daim ntawv no, peb yuav tham txog cov txiaj ntsig ntawm HEC hauv cov xim latex.
Txhim kho viscosity tswj
Ib qho txiaj ntsig tseem ceeb ntawm HEC hauv cov xim latex yog nws lub peev xwm los txhim kho viscosity tswj.HEC yog cov dej-soluble polymer uas swells hauv dej los tsim cov khoom zoo li gel.HEC kuj txo qis sagging thiab txhim kho zaj duab xis tsim, uas ua rau smoother thiab ntau dua tiav.
Txhim kho dej tuav
HEC yog ib qho hydrophilic polymer uas nqus dej thiab khaws cia rau hauv cov xim pleev xim..Qhov no pab tiv thaiv cov xim ntawm cov xim kom qhuav sai sai thiab ua kom muaj kev sib faib ntau dua ntawm cov xim..HEC kuj txhim kho lub sijhawm qhib ntawm cov xim, cov nqi ntawm cov xim. lub sij hawm thaum lub sij hawm cov xim tseem ua hauj lwm nyob rau saum npoo..Qhov no yog tshwj xeeb tshaj yog zoo rau cov hauj lwm xim loj, raws li nws tso cai rau lub sij hawm ntau los thov cov xim sib npaug.
Txhim kho Adhesion
HEC txhim khu cov adhesion ntawm latex xim rau ntau yam substrates, nrog rau cov ntoo, hlau thiab pob zeb..Qhov no yog tshwj xeeb tshaj yog zoo nyob rau hauv sab nrauv daim ntaub ntawv, qhov twg raug rau lub ntsiab yuav ua rau cov xim rau tev los yog flake tawm..HEC tsub kom lub binding muaj peev xwm. cov xim, ua rau muaj zog thiab ruaj khov xim zaj duab xis.
Txhim kho Stain Resistance
HEC kuj tseem txhim kho qhov tsis zoo ntawm cov xim latex..HEC tsim cov yeeb yaj kiab tiv thaiv ntawm cov xim pleev xim, uas pab tiv thaiv kev nkag mus ntawm cov kua thiab stains. .
Txhim kho xim txais
HEC kuj tseem txhim kho qhov kev lees txais xim ntawm cov xim pleev xim rau xim..HEC pab nthuav cov xim sib npaug thoob plaws hauv cov xim, ua rau cov xim muaj zog dua thiab txawm tias xim..
Nyob rau hauv xaus, hydroxyethyl cellulose yog ib qho tseem ceeb muaj nyob rau hauv cov xim latex, txhim kho lawv cov kev ua tau zoo ntawm ntau txoj kev..HEC txhim kho viscosity tswj, dej tuav, adhesion, stain resistance, thiab xim txais, uas ua rau muaj kev ruaj khov, ntev ntev, thiab ntxim nyiam xim zaj duab xis.Raws li qhov kev thov rau cov xim zoo nkauj txuas ntxiv zuj zus, kev siv HEC xav tias yuav nce ntxiv, tsav kev tsim kho tshiab thiab kev nce qib hauv kev lag luam xim.
