Focus on Cellulose ethers

Impembelelo ye-Cellulose Ether kwi-Gypsum kunye ne-Cementitious Mortar

Iimveliso ze-ether ze-cellulose zisetyenziswa ngokubanzi ukuphucula ukusebenza kwezinto zokwakha ze-hydraulic, ezifana ne-gypsum kunye ne-samente. Kwi-gypsum kunye ne-samente-based mortars, iphucula ukugcinwa kwamanzi, yandisa ukulungiswa kunye namaxesha avulekileyo, kunye nokunciphisa ukuthoba.

1. Ukugcinwa kwamanzi

I-ether ye-cellulose ikhusela ukufuma ekungeneni eludongeni. Ubungakanani obufanelekileyo bamanzi buhlala kumdaka, ukuze i-gypsum kunye nesamente zibe nexesha elide lokumanzisa. Ukugcinwa kwamanzi kuhambelana ngokuthe ngqo kwi-viscosity yesisombululo se-cellulose ether kwi-mortar. Ukuphakama kwe-viscosity, ngcono ukugcinwa kwamanzi. Emva kokuba into yokufuma inyuka, ukugcinwa kwamanzi kuncipha. Ngenxa yokuba umlinganiselo ofanayo wesisombululo se-cellulose ether, ukwanda kwamanzi kuthetha ukuhla kwe-viscosity. Ukuphuculwa kokugcinwa kwamanzi kuya kukhokelela ekwandisweni kwexesha lokulungisa udaka olwakhiwayo.

2. Ukunciphisa i-viscosity kunye nokuphucula ukusebenza

Isezantsi i-viscosity ye-cellulose ether esetyenzisiweyo, iyancipha i-viscosity yodaka kwaye ngaloo ndlela ingcono ukusebenza. Nangona kunjalo, i-viscosity ephantsi ye-cellulose ether ine-dosage ephezulu ngenxa yokugcinwa kwayo okuphantsi kwamanzi.

3. Anti-sagging

Udaka oluqinileyo olumelana nokurhawuka luthetha ukuba udaka olugalelwe kumaleko ashinyeneyo alunabungozi bokuhexa okanye ukubaleka ukuya ezantsi. Ukumelana ne-Sag kunokuphuculwa nge-cellulose. I-ether ye-cellulose inokubonelela ngcono ukuxhathisa kwe-sag yodaka.

4. Umxholo webhabhula

Umxholo we-bubble womoya ophezulu uphumela kwisivuno esingcono sodaka kunye nokusebenza, ukunciphisa ukubunjwa kokuqhekeka. Kwakhona kunciphisa ixabiso lokuqina, okubangelwa "i-liquefaction" isenzeko. Isiqulatho seqamza lomoya sikholisa ukuxhomekeka kwixesha lokuzamisa.
