Impembelelo ebalulekileyo ye "Thickener" kwiNtsebenzo ye-Cellulose Ether kwi-Mortars

I-ether ye-cellulose yinto esetyenziswa ngokuqhelekileyo kwi-mortars, eluhlobo lwezixhobo zokwakha ezisetyenziselwa ukwakha. Isetyenziselwa ukuphucula iimpawu zodaka, kubandakanywa nokusebenza kwayo, ukunamathela, kunye nokuqina. Enye into ebalulekileyo echaphazela ukusebenza kwe-cellulose ether kwi-mortars kukukhethwa kwe-thickener. Kweli nqaku, siza kuxubusha impembelelo ebalulekileyo ye-thickener ekusebenzeni kwe-cellulose ether kwi-mortars.

I-Thickener luhlobo lwezongezo ezisetyenziselwa ukwandisa i-viscosity yolwelo. Ihlala yongezwa kwi-cellulose ether kwi-mortars ukuphucula ukusebenza kwayo. Ukukhethwa kwe-thickener kunokuba nempembelelo ebalulekileyo kwiipropati zodaka, kubandakanywa nokusebenza kwayo, ukugcinwa kwamanzi, kunye nokuxhatshazwa kwe-sag.

Enye yezona zixhaphakileyo zisetyenziswa kakhulu kwi-cellulose ether mortars yi-hydroxyethyl cellulose (HEC). I-HEC yipolymer enyibilikayo emanzini eyaziwa ngokugqwesa kwayo okugqwesileyo kunye neempawu zokugcina amanzi. Ikwayaziwa ngokuba namandla okuphucula ukusebenza kodaka, okwenza kube lula ukuyifaka kunye nokubumba.

Esinye isityebi esiqhele ukusetyenziswa kwi-cellulose ether mortars yi-methyl cellulose (MC). I-MC yipolymer enyibilikayo emanzini eyaziwa ngokugqwesa kwayo okugqwesileyo kunye neempawu zokugcina amanzi. Ikwaziwa ngokukwazi kwayo ukuphucula ukuxhathisa kwe-sag yodaka, okunceda ukuyithintela ekutyibilikeni okanye ukudilika kwiindawo ezithe nkqo.

Ukukhethwa kwe-thickener kunokuchaphazela ixesha lokumisela udaka. Ezinye i-thickeners, ezifana ne-MC, zinokukhawulezisa ixesha lokumisela udaka, ngelixa ezinye, ezifana ne-HEC, zinokuyicotha. Oku kunokuba yingqwalasela ebalulekileyo kwiiprojekthi zokwakha apho ixesha lokumisela kufuneka lilawulwe ngenyameko.

Umthamo we-thickener osetyenzisiweyo unokuba nefuthe kwiipropati zodaka. Ukujiyisa kakhulu kunokwenza udaka lubene-viscous kakhulu kwaye kube nzima ukusebenza ngalo, ngelixa ukujiya kuncinci kunokukhokelela kudaka oluncinci kakhulu kwaye oluthanda ukugrumba okanye ukudilika.

Ukongeza kwi-HEC kunye ne-MC, kukho ezinye izinto ezininzi ezinokuthi zisetyenziswe kwi-cellulose ether mortars, kuquka i-carboxymethyl cellulose (CMC) kunye ne-hydroxypropyl methyl cellulose (HPMC). I-thickener nganye ineempawu zayo ezizodwa kwaye ingasetyenziselwa ukufezekisa iimpawu ezithile zokusebenza kumdaka.

Isishwankathelo, ukhetho lwe-thickener lunokuba nempembelelo enkulu ekusebenzeni kwe-cellulose ether kumdaka. Iipropati ze-thickener, kubandakanywa ukukwazi ukujiya, ukugcinwa kwamanzi, ukuxhathisa i-sag, kunye nefuthe kwixesha lokumisela, kufuneka ziqwalaselwe ngononophelo xa ukhetha i-thickener yokusetyenziswa kwi-mortar. Ngokukhetha isixhobo sokujiyisa esifanelekileyo size sisetyenziswe ngomlinganiselo ofanelekileyo, abakhi neengcali zokwakha banokuqinisekisa ukuba udaka lwabo lusebenza kakuhle yaye luyahlangabezana neemfuneko ezithile zeprojekthi yabo yokwakha.
