3.Hydroxyethyl Cellulose (HEC) Daim Ntawv Thov:

Nyob rau hauv cov xim raws li dej, nws plays lub luag hauj lwm ntawm dispersing thiab tiv thaiv gels, txhim kho cov tshuaj tiv thaiv stability ntawm agglomerate system, kom ntseeg tau homogeneous faib ntawm cov xim thiab cov khoom, thiab muab cov nyhuv ntawm thickening, txhim kho fluidity.

Nyob rau hauv cov roj drilling, nws yog siv raws li stabilizer thiab thickening tus neeg saib xyuas, lubricating tus neeg saib xyuas rau zoo drilling, ua kom tiav thiab consolidating muab slurry ib tug zoo fluidity thiab stability.

Hauv kev tsim kho, HEC tuaj yeem siv los ua tus neeg sawv cev thickening thiab cohesive tus neeg sawv cev los txhim kho cov dej ntws thiab kev ua haujlwm, ua kom lub zog pib gelling thiab tsis txhob tawg.

Nyob rau hauv txhuam thiab cohering plaster, nws yuav pom tau tias nce dej tuav thiab coherence zog.

Nyob rau hauv niaj hnub siv tshuaj xws li tshuaj txhuam hniav nws muab ib tug zoo lub cev thiab tshuaj lub cev, ua rau nws zoo nyob rau hauv cov duab, ntev lub sij hawm cia, nyuaj yuav qhuav thiab permeated.

Hauv kev ua kom zoo nkauj, nws tuaj yeem ua kom cov khoom ntom ntom, ntxiv lubrication thiab smoothness.

Tsis tas li ntawd, nws muaj ntau daim ntawv thov nyob rau hauv number case, textile dyeing & printing, ntawv ua, kws, zaub mov, ua liaj ua teb thiab lwm yam.

4.Hydroxyethyl Cellulose (HEC) Siv txoj kev:

Thawj Txoj Kev: Muab tso rau hauv

1. Ncuav dej ntshiab rau hauv lub thoob uas muaj cov stirrer.

2. Thaum pib maj mam do, sib npaug sib npaug HEC rau hauv kev daws.

3. Do kom txog thaum tag nrho cov HEC granules tag nrho wetted.

4. Ua ntej muab tso rau hauv anti-mildew tus neeg sawv cev, ces ntxiv nyob rau hauv additives xws li pigment, disperser thiab lwm yam.

5. Nqa mus rau stirring kom txog thaum tag nrho cov HEC thiab additives tag nrho yaj (viscosity nyob rau hauv cov tshuaj pom tseeb nce), ces muab tso rau hauv lwm cov khoom xyaw rau react.

Txoj Kev Thib Ob: Npaj Niam Dej Haus rau Kev Siv

Ua ntej npaj tuab niam cawv, ces muab tso rau hauv cov khoom.Qhov kom zoo dua ntawm txoj kev yog yooj, cov cawv yuav ncaj qha muab tso rau hauv cov khoom.Cov txheej txheem thiab txoj kev siv yog tib yam li 1-4 hauv txoj kev (Ⅰ), ua Nco ntsoov do kom txog thaum tag nrho yaj mus rau hauv cov kua nplaum thiab tuab thiab muab cov tshuaj tiv thaiv kab mob rau hauv niam cawv kom ntxov li sai tau.

Txoj Kev Thib Peb: Npaj cov khoom zoo li Gruel rau kev siv

Txij li cov kuab tshuaj organic tsis yog cov kuab tshuaj rau HEC, lawv tuaj yeem siv los npaj cov khoom zoo li gruel.Cov khoom siv feem ntau yog ethylene glycol, propylene glycol thiab film-forming agent (hexamethylene-glycol, diethyl glycol butyl acetate etc.) Yog li ntawd yog dej khov. dej, nws kuj tuaj yeem npaj ua ke nrog cov kuab tshuaj organic rau hauv cov khoom zoo li gruel.

Cov khoom zoo li Gruel tuaj yeem muab tso rau hauv cov khoom lag luam vim tias HEC hauv cov khoom zoo li cov khoom siv tau ntub dej thiab o, muab tso rau hauv cov khoom nws dissolves tam sim ntawd thiab txhawb cov thickening, tab sis ua kom nplawm kom txog thaum nws tag nrho yaj.

Feem ntau cov khoom zoo li gruel yog tau los ntawm kev sib xyaw cov kuab tshuaj organic los yog dej khov nrog HEC hauv ib feem ntawm 6: 1, tom qab 5-30 feeb HEC hydrolyzes thiab tshwj xeeb swells.Cov txheej txheem tsis yog siv rau lub caij ntuj sov vim huab cua kub.

5. Daim Ntawv Qhia Txog Kev Lag Luam Xim

Siab Thickening Effects

Hydroxyethy Cellulose muab cov xim latex tshwj xeeb tshaj yog cov xim PVA siab nrog kev ua haujlwm zoo heev.Thaum cov xim yog tuab paste, tsis muaj flocculation yuav tshwm sim.

Hydroxyethyl Cellulose muaj cov nyhuv thickening ntau dua, yog li tuaj yeem txo qhov ntau npaum li cas, txhim kho tus nqi tsim nyog, thiab txhim kho kev ntxuav cov xim.

Zoo heev Rheological Properties

Cov tshuaj aqueous ntawm Hydroxyethyl Cellulose yog ib qho uas tsis yog-Newtonian system, thiab cov khoom ntawm cov tshuaj hu ua thixotropy.

Nyob rau hauv lub xeev ruaj khov, tom qab cov khoom tiav lawm, txheej txheej txheej tuaj yeem tswj tau qhov zoo tshaj plaws thickening mob thiab tuaj yeem qhib lub xeev.

Hauv lub xeev pov tseg, lub kaw lus tuaj yeem khaws cov viscosity nruab nrab, ua cov khoom lag luam zoo heev, thiab tsis tawg.

Thaum txhuam hniav thiab cov menyuam txheej, cov khoom yog ib qho yooj yim rau kev sib kis ntawm lub substrate, yog li yooj yim rau kev tsim kho, thiab lub sijhawm no, muaj kev sib txhuam zoo.

Thaum kawg, tom qab txheej txheej ntawm cov xim tiav, lub viscosity ntawm lub system yuav tam sim ntawd rov qab los, thiab cov xim yuav tam sim ntawd tsim sagging khoom.

Dispersion thiab Solubility

Hydroxyethy Cellulose yog txhua yam kho los ntawm kev ncua sij hawm, thiab nyob rau hauv cov ntaub ntawv ntawm ntxiv qhuav hmoov, muaj peev xwm tiv thaiv caking zoo thiab xyuas kom meej hydration pib tom qab lub txaus dispersion ntawm HEC hmoov.

Hydroxyethyl Cellulose tom qab kho kom zoo saum npoo tuaj yeem tswj tau qhov kev sib cais thiab viscosity nce tus nqi ntawm cov khoom.

Cia ruaj khov

Hydroxyethyl Cellulose muaj qhov ua tau zoo ntawm cov kab mob mildew-resistant, muab sijhawm txaus rau cov xim, thiab tiv thaiv kev sib haum xeeb ntawm cov xim thiab cov fillers.a
