Iko Kukosha Kufurira kwe "Thickener" paKuitwa kweCellulose Ether muMortars

Cellulose ether inowanzoshandiswa mudhaka, inova rudzi rwezvinhu zvekuvaka zvinoshandiswa pakuvaka. Inoshandiswa kuvandudza zvimiro zvedhaka, kusanganisira kushanda kwayo, kunamatira, uye kusimba. Chimwe chinhu chakakosha chinokanganisa kushanda kwe cellulose ether mumatope ndiko kusarudzwa kwekukora. Muchikamu chino, tichakurukura zvakakosha pesvedzero ye thickener pakushanda kwe cellulose ether mumatope.

Thickener imhando yekuwedzera iyo inoshandiswa kuwedzera viscosity yemvura. Inowanzowedzerwa kune cellulose ether mumatope kuti ivandudze kushanda kwayo. Sarudzo yekukora inogona kuve nekukanganisa kwakakura pazvinhu zvedhaka, kusanganisira kushanda kwayo, kuchengetedza mvura, uye sag kuramba.

Imwe yeanowanzo shandiswa gobvu mumadhaka e cellulose ether ihydroxyethyl cellulose (HEC). HEC ipolymer inonyungudika nemvura inozivikanwa nekunaka kwayo kukora uye kuchengetedza mvura. Iyo inozivikanwa zvakare nekugona kwayo kuvandudza kushanda kwedhaka, izvo zvinoita kuti zvive nyore kuisa uye kuumba.

Imwe inowanzoshandiswa thickener mu cellulose ether mortars imethyl cellulose (MC). MC i polymer inonyungudika nemvura inozivikanwa nekunaka kwayo kukora uye kuchengetedza mvura. Iyo inozivikanwa zvakare nekugona kwayo kuvandudza sag kuramba kwedhaka, iyo inobatsira kuidzivirira kubva pakutsvedza kana kudonhera panzvimbo dzakamira.

Sarudzo ye thickener inogonawo kukanganisa nguva yekugadzika kwedhaka. Mamwe makobvu, akadai seMC, anogona kukurumidza kugadzika nguva yedhaka, nepo mamwe, akadai seHEC, anogona kunonoka. Ikoku kunogona kuva kurangarirwa kunokosha muzvirongwa zvokuvaka uko nguva yokugadza inoda kudzorwa nokungwarira.

Huwandu hwehukohwe hunoshandiswa hunogonawo kuve nemhedzisiro pane zvimiro zvedhaka. Kunyanya kukora kunogona kuita kuti dhaka rive rakanyanya kuoneka uye rakaoma kushanda naro, nepo kukora kushoma kunogona kuguma nedhaka rakanyanya kutetepa uye rinowanzodonha kana kudonha.

Kuwedzera kune HEC uye MC, kune akati wandei mamwe makobvu anogona kushandiswa mune cellulose ether dhaka, kusanganisira carboxymethyl cellulose (CMC) uye hydroxypropyl methyl cellulose (HPMC). Imwe neimwe thickener ine yayo yakasarudzika zvivakwa uye inogona kushandiswa kuzadzisa chaiwo maitiro ekuita mudhaka.

Mukupfupisa, kusarudzwa kwekukora kunogona kuita zvakakosha pakuita kwe cellulose ether mumatope. Zvimiro zveiyo thickener, kusanganisira kugona kwayo kukora, kuchengetedza mvura, sag resistance, uye kukanganisa pakugadzirisa nguva, zvinofanirwa kutariswa zvakanyanya pakusarudza gobvu yekushandisa mumatope. Nekusarudza gobvu rakakodzera uye kurishandisa muchiyero chakakodzera, vavaki nenyanzvi dzekuvaka vanogona kuona kuti dhaka ravo rinoita zvakanaka uye rinozadzisa zvinodiwa chaizvo zvechirongwa chavo chekuvaka.
