1. Izinkinga ezivamile ku-putty powder
Ukomisa ngokushesha: Lokhu kubangelwa ikakhulukazi inani le-lime calcium powder elingeziwe (likhulu kakhulu, inani le-lime calcium powder elisetshenziswe ku-putty formula lingancishiswa ngokufanele) lihlobene nezinga lokugcinwa kwamanzi efayibha, futhi kuhlobene futhi. okuhlobene nokoma kodonga.
Peel bese ugoqa.Lokhu kuhlobene nesilinganiso sokugcinwa kwamanzi, okulula ukwenzeka lapho i-viscosity ye-cellulose iphansi noma inani lokwengeza lincane.
I-De-powdering of the internal wall putty powder: Lokhu kuhlobene nenani le-ash calcium powder eyengeziwe (inani le-ash calcium powder ku-putty formula lincane kakhulu noma ubumsulwa be-ash calcium powder buphansi kakhulu, kanye nenani lomlotha. I-calcium powder kufomula ye-putty powder kufanele ikhuliswe ngokufanele) Ngesikhathi esifanayo, iphinde ihlobane nenani kanye nekhwalithi ye-cellulose, ebonakala ngenani lokugcinwa kwamanzi lomkhiqizo.Izinga lokugcinwa kwamanzi liphansi, futhi isikhathi somlotha we-calcium powder (i-calcium oxide ku-ash calcium powder ayiguqulwa ngokugcwele ku-calcium hydroxide) asanele.,kubangelwa.
Amabhamuza: Lokhu kuhlobene nokuswakama okomile kanye nokucaba kodonga, futhi kuhlobene nokwakhiwa.
Kuvela amaphuzu.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 ayinakho amandla ahlangene ngesikhathi esifanayo.Ngaphezu kwalokho, lesi simo senzeka nangemikhiqizo efana ne-carboxymethyl exutshwe ne-cellulose.
Ukubukeka kwama-craters kanye nama-pinholes: Lokhu ngokusobala kuhlobene nokushuba kwesimo samanzi se-hydroxypropyl methylcellulose aqueous solution.Ukungezwani kwetafula lamanzi kwesisombululo samanzi se-hydroxyethyl akubonakali.Kungaba kuhle ukwenza ukwelashwa kokuqeda.
Ngemuva kokuthi i-putty isomile, kulula ukuqhekeka nokuphenduka okuphuzi: lokhu kuhlobene nokwengezwa kwenani elikhulu le-ash calcium powder.Uma inani le-ash calcium powder likhulu kakhulu, ubulukhuni be-putty powder buzokhula ngemva kokumisa.Ubulukhuni kuphela ngaphandle kokuguquguquka buzoqhekeka kalula, ikakhulukazi Kulula ukuqhekeka uma ungaphansi kwamandla angaphandle.Ibuye ihlotshaniswe nokuqukethwe okuphezulu kwe-calcium oxide ku-ash calcium powder.
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. 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 izwakala isindayo lapho ikhuhla.Inani elinconyiwe le-putty yezindonga zangaphakathi yi-3-5 kg, futhi i-viscosity yi-80,000-100,000.
4. Kungani i-cellulose ye-viscosity efanayo izizwa ihlukile ebusika nasehlobo?
Ngenxa ye-gelation eshisayo yomkhiqizo, i-viscosity ye-putty ne-mortar 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 ukwandisa inani le-cellulose, nokukhetha umkhiqizo onokushisa kwe-gel ephakeme.Zama ukungasebenzisi i-methyl cellulose ehlobo.Izinga lokushisa lejeli liphakathi kuka-55 degrees, izinga lokushisa liphakeme kancane, futhi i-viscosity yayo izothinteka kakhulu.
