Cov nyhuv ntawm HEC ntawm ib puag ncig kev ua haujlwm ntawm cov txheej txheem

Hauv kev lag luam niaj hnub ua lag luam, ib puag ncig kev ua tau zoo tau dhau los ua ib qho ntawm cov ntsuas tseem ceeb rau ntsuas cov khoom kom zoo.Hydroxyethyl cellulose (HEC), raws li ib qho dej-soluble polymer thickener thiab stabilizer, yog siv dav hauv cov duab kos duab kos, cov xim yas thiab dej txheej txheem. Hec tsis tsuas yog txhim kho kev ua tiav kev ua tiav ntawm cov txheej txheem, tab sis kuj tseem muaj kev cuam tshuam zoo heev rau lawv cov khoom ib puag ncig.

1. Qhov chaw thiab cov yam ntxwv ntawm Hec

HEC yog cov duab sib txuas polymer tau los ntawm kev hloov tshuaj lom neeg ntawm cov cellulose ntuj, uas yog biodegradable thiab nokic. Raws li cov khoom siv ntuj tsim, nws cov txheej txheem tsim thiab siv cov txheej txheem muaj qhov cuam tshuam tsawg rau ib puag ncig. HEC tuaj yeem tshem tawm cov ntawv tawg, kho viscosity thiab tswj viscosity thiab tswj cov tshuab txiav tawm, thaum tsis txhob siv cov tshuaj cais cov tshuaj sib ntxiv uas muaj kev phom sij rau ib puag ncig. Cov yam ntxwv ua rau HEC kom dhau los ua cov khoom tseem ceeb hauv cov txheej txheem ua phooj ywg zoo.

 

2. Kev ua kom zoo ntawm cov txheej sib xyaw

Hec txo kev cia siab txog ntawm cov khoom xyaw muaj kuab lom los ntawm kev txhim kho txheej txheej. Piv txwv li, hauv cov txheej txheej hauv dej, HEC tuaj yeem txhim kho qhov tsis sib xws ntawm cov pigments, thiab txo cov tshuaj tiv thaiv kev phom sij. Ib qho ntxiv, HEC muaj cov dej ua kom zoo thiab cov ntsev tsis kam, uas yuav pab tau cov txheej txheem uas tsis muaj peev xwm hauv cov hom phiaj loj, yog li kev tiv thaiv ib puag ncig ib puag ncig.

 

3. Kev tswj hwm

Volatile organic cov tebchaw (VOC) yog ib qho ntawm cov khoom muaj kuab paug nyob rau hauv ib puag ncig lub tsho tiv no thiab ua rau ib puag ncig kev noj qab haus huv thiab kev noj qab haus huv. Raws li cov tuab dua, HEC tuaj yeem ua kom tiav hauv dej thiab yog qhov sib piv nrog cov dej sib dhos, ua kom nruj kev vam khom rau cov kuab tshuaj lom neeg thiab txo lub suab tawm ntawm lub hauv paus. Piv nrog cov kev ua yeeb yam ua kom zoo li silicones xws li silicones lossis acrylics, daim ntawv thov ntawm HEC yog ib puag ncig ib puag ncig thaum tswj xyuas kev ua tau zoo ntawm cov txheej txheem.

4. Kev txhawb nqa ntawm kev txhim kho kom ruaj khov

Daim ntawv thov ntawm HEC tsis yog tsuas yog ua kom muaj kev tawm tsam ntawm cov ntaub ntawv ua phooj ywg zoo, tab sis kuj txhawb nqa kev txhim kho kom muaj kev lag luam. Ntawm ib sab tes, raws li ib qho khoom siv rho tawm los ntawm cov khoom siv tau muaj dua tshiab, HEC cov kev tsim khoom ntau dua ntawm cov pob txha roj; Ntawm qhov tod tes, qhov siab ua tau zoo ntawm HEC hauv lub sijhawm ua haujlwm ntev ntev lub neej ntawm cov khoom lag luam, yog li txo cov khoom siv thiab cov khoom pov tseg. Piv txwv li, cov qauv zoo nkauj, qauv nrog HEC tuaj yeem txhim kho cov txhuam hniav tiv thaiv thiab cov khoom siv los tiv thaiv cov khoom siv uas ua kom muaj kev tsim kho thiab kev ua ib puag ncig.

 

5. Kev Sib Tw thiab Kev Loj Hlob

Txawm hais tias HEC muaj qhov zoo tseem ceeb hauv kev ua yeeb yam ib puag ncig ntawm cov xim tha xim, nws daim ntawv thov tseem tau ntsib qee cov kev cov kev sib tw. Piv txwv li, kev sib cais thiab shear stability ntawm HEC yuav raug txwv nyob rau hauv cov qauv tshwj xeeb, thiab nws cov kev ua tau zoo yuav tsum tau txhim kho los ntawm kev txhim kho ntxiv. Ib qho ntxiv, nrog kev sib txuas lus nruj ntawm cov kev cai ib puag ncig, qhov kev thov rau cov tshuaj lom xyoob ntoo hauv cov xim muaj xim kuj nce ntxiv. Yuav ua li cas los sib txuas Hec nrog lwm cov ntaub ntawv ntsuab yog kev tshawb nrhiav yav tom ntej. Piv txwv li, kev txhim kho cov kab ke ntawm HEC thiab Nanomaterials tsis tuaj yeem pab txhawb ntxiv cov xim hlau thiab tiv thaiv kom tau raws li ib puag ncig siab dua.

Raws li ib puag ncig cov phooj ywg thickener muab tau los ntawm cov cellulose ntuj,Tus paTseem txhim kho kom muaj kev ua yeeb yam ib puag ncig ntawm cov xim tha xim. Nws muab kev txhawb nqa tseem ceeb rau cov kev hloov pauv ntsuab ntawm kev lag luam pleev xim tshiab niaj hnub los ntawm kev txo cov tshuaj tiv thaiv voc, ua kom cov xim ua kom zoo, thiab txhawb nqa kev txhim kho kom ruaj khov. Txawm hais tias qee qhov nyuaj kev nyuaj tseem yuav tsum tau kov yeej, qhov kev thov dav ntawm HEC hauv cov xim zoo nkauj ib puag ncig yog qhov zoo thiab muaj peev xwm. Tawm tsam cov backdrop ntawm nce ntiaj teb ib puag ncig kev ua haujlwm thoob ntiaj teb ib puag ncig, HEC yuav txuas ntxiv mus rau kev lag luam txheej loj dua rau lub neej yav tom ntej.
