Izinkinga ezivamile ze-putty engavimbeli amanzi ezindongeni zangaphakathi

1. Izinkinga ezijwayelekile ku-putty powder:

1.1 Yoma ngokushesha.Lokhu ikakhulukazi kuhlobene nokwengezwa kwe-calcium yomlotha kanye nezinga lokugcinwa kwamanzi kwe-fiber, futhi kuhlobene nokomisa kodonga.

1.2 Ukucwecwa nokugoqa.Lokhu kuhlobene nesilinganiso sokugcinwa kwamanzi, okulula ukwenzeka lapho i-viscosity ye-cellulose iphansi noma inani lokwengeza lincane.

1.3 Ukukhipha impuphu.Lokhu kuhlobene nenani le-ash calcium eyengeziwe, futhi kuhlobene nenani kanye nekhwalithi ye-cellulose engeziwe.Kubonakala ngezinga lokugcinwa kwamanzi lomkhiqizo.Izinga lokugcinwa kwamanzi liphansi futhi isikhathi sokugeleza kwe-ash calcium asanele.

1.4 Ukubhakuzisa.Lokhu kuhlobene nomswakama owomile kanye nokucaba kodonga, futhi kuhlobene nokwakhiwa.

1.5 Kuvela iphinikhodi.Lokhu kuhlobene ne-cellulose, enezinto ezimbi zokwakha ifilimu.Ngesikhathi esifanayo, ukungcola ku-cellulose kusabela kancane nge-ash calcium.Uma ukusabela kunzima, i-putty powder izovela esimweni sezinsalela ze-bean curd.Ayikwazi ukufakwa odongeni, futhi ayinawo amandla ahlangene ngesikhathi esifanayo.Ngaphezu kwalokho, lesi simo siphinde senzeka ngemikhiqizo efana namaqembu e-carboxyl angezwe ku-cellulose.

1.6 Kuvela izintabamlilo nezimbobo.Lokhu ngokusobala kuhlobene nokushuba kwesimo samanzi sesisombululo samanzi se-hydroxypropyl methylcellulose.Ukungezwani kwetafula lamanzi kwesisombululo samanzi se-hydroxyethyl akubonakali.Kungaba kuhle ukwenza ukwelashwa kokuqeda.

1.7 Ngemva kokuba i-putty yomile, kulula ukuqhekeka futhi ibe phuzi.Lokhu kuhlobene nokwengezwa kwenani elikhulu le-calcium empunga.Uma inani le-calcium empunga lengezwa kakhulu, ubulukhuni be-putty powder buzokhula ngemva kokumisa.Ubulukhuni kuphela futhi akukho ukuguquguquka okuzoqhekeka kalula, ikakhulukazi uma kungaphansi kwamandla angaphandle.Iphinde ihlobane nokuqukethwe okuphezulu kwe-calcium oxide ku-calcium empunga, eyethulwe ngaphambili.

2. Kungani i-putty powder iba mncane ngemva kokwengeza amanzi?

I-Cellulose isetshenziswa njenge-thickener kanye ne-ejenti yokugcina amanzi ku-putty.Ngenxa ye-thixotropy ye-cellulose ngokwayo, ukungezwa kwe-cellulose ku-putty powder nakho kuholela ku-thixotropy ngemva kokwengeza amanzi ku-putty.Le thixotropy ibangelwa ukubhujiswa kwesakhiwo esihlanganisiwe esikhululekile sezingxenye ku-putty powder.Lesi sakhiwo sivuka ekuphumuleni futhi siphuka ngaphansi kokucindezeleka.Okusho ukuthi, i-viscosity iyancipha ngaphansi kokugqugquzela, futhi i-viscosity iyalulama lapho imile.

3. Kungani i-putty isindayo ohlelweni lokukhuhla?

Kulokhu, i-viscosity ye-cellulose esetshenziswa ngokuvamile iphezulu kakhulu.Abanye abakhiqizi basebenzisa i-cellulose engu-200,000 ukwenza i-putty.I-putty ekhiqizwa ngale ndlela ine-viscosity ephezulu, ngakho izwa isindayo uma ikhuhla.Inani elinconyiwe le-putty yezindonga zangaphakathi yi-3-5 kg, futhi i-viscosity yi-80,000-100,000.

4. Kungani i-putty ne-mortar eyenziwe nge-cellulose ene-viscosity efanayo izizwa ihlukile ebusika nasehlobo?

Ngenxa ye-gelation eshisayo yomkhiqizo, i-viscosity yomkhiqizo izokwehla kancane kancane ngokunyuka kwezinga lokushisa.Lapho izinga lokushisa lidlula izinga lokushisa lejeli lomkhiqizo, umkhiqizo uzodonswa emanzini futhi ulahlekelwe yi-viscosity yawo.Izinga lokushisa lekamelo ehlobo livame ukuba ngaphezu kwama-degree angu-30, okuhluke kakhulu ekushiseni kwasebusika, ngakho-ke i-viscosity iphansi.Kunconywa ukukhetha umkhiqizo one-viscosity ephakeme ehlobo, noma ukwandisa inani le-cellulose, bese ukhetha umkhiqizo onokushisa kwe-gel ephakeme.Zama ukukhetha umkhiqizo onokushisa kwejeli ngaphezu kwama-70 degrees.Zama ukungasebenzisi i-methyl cellulose ehlobo, izinga lokushisa layo lejeli lingama-degree angama-55, uma izinga lokushisa liphakeme kancane, i-viscosity yayo izothinteka kakhulu.
