Uma sisebenzisa i-putty powder, ngokuvamile kuzoba nezinkinga, ngakho-ke asazi isizathu. Ngicabanga ukuthi kufanele kube nezinhlobo eziyisikhombisa zezinkinga ezivame ukuvela ku-putty powder!
Omunye: Kwenze ngokushesha. Lokhu ikakhulukazi kuhlobene nokwengezwa kwe-calcium yomlotha kanye nezinga lokugcinwa kwamanzi kwe-fiber, futhi kuhlobene nokomisa kodonga.
Okubili: ikhasi bese ugoqa. Lokhu kuhlobene nesilinganiso sokugcinwa kwamanzi, okulula ukwenzeka lapho i-viscosity ye-cellulose iphansi noma inani lokwengeza lincane.
Okwesithathu: ukususwa kwempushana. 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.
Okwesine: Amabhamuza. Lokhu kuhlobene nomswakama owomile kanye nokucaba kodonga, futhi kuhlobene nokwakhiwa.
Eyesihlanu: 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.
Isithupha: Kuvela imihume yezintabamlilo nemigodi emincane. Lokhu ngokusobala kuhlobene nokushuba kwesimo samanzi sesisombululo samanzi se-hydroxypropyl methylcellulose, kodwa ukungezwani kwamanzi esixazululo esinamanzi se-hydroxyethyl akubonakali. Kuyoba ngcono ukwenza ukwelashwa okulula.
Oyisikhombisa: 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-gray calcium.
1. Kungani i-putty powder iba mncane ngemva kokwengeza amanzi?
I-Cellulose ether isetshenziswa njenge-ejenti ejiya futhi egcina 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.
2. Yisiphi isizathu esenza ukuthi i-putty ibe nzima kakhulu ekukhunjweni?
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.
3. 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 lapho usebenzisa umkhiqizo ehlobo, noma ukhuphule inani le-cellulose, bese ukhetha umkhiqizo onezinga lokushisa eliphakeme lejeli.
