1. Izinkinga ezivamile ku-putty powder
Yoma ngokushesha.Lokhu ikakhulukazi ngoba inani le-ash calcium powder elingeziwe (likhulu kakhulu, inani le-ash calcium powder elisetshenziswe ku-putty formula lingancishiswa ngokufanele) lihlobene nesilinganiso sokugcinwa kwamanzi kwe-fiber, futhi ihlobene nokoma. yodonga.
Peel bese ugoqa.Lokhu kuhlobene nesilinganiso sokugcinwa kwamanzi, okulula ukwenzeka lapho i-viscosity ye-cellulose iphansi noma inani lokwengeza lincane.
I-De-powdering ye-interior wall putty powder.Lokhu kuhlobene nenani le-ash calcium powder eyengeziwe (inani le-ash calcium powder kufomula ye-putty lincane kakhulu noma ukuhlanzeka kwe-ash calcium powder kuphansi kakhulu, futhi inani le-ash calcium powder kufomula ye-putty powder kufanele kwandiswe ngokufanelekile), futhi kuhlobene nokwengezwa kwe-cellulose.Kunobudlelwano phakathi kobuningi nekhwalithi, okubonakala ngenani lokugcinwa kwamanzi lomkhiqizo.Izinga lokugcinwa kwamanzi liphansi, futhi i-ash calcium powder (i-calcium oxide ku-ash calcium powder ayiguqulwa ngokugcwele ku-calcium hydroxide ye-hydration) isikhathi asanele, esibangelwa.
bubbly.Lokhu kuhlobene nomswakama owomile 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.
Kuvela ama-craters nama-pinnholes.Lokhu ngokusobala kuhlobene nokushuba kwesimo samanzi sesisombululo samanzi se-hydroxypropyl methylcellulose.Ukungezwani kwetafula lamanzi kwesisombululo samanzi se-hydroxyethyl akubonakali.Kungaba kuhle ukwenza ukwelashwa kokuqeda.
Ngemuva kokuthi i-putty yomile, kulula ukuqhekeka futhi ibe phuzi.Lokhu kuhlobene nokwengezwa kwenani elikhulu le-ash-calcium powder.Uma inani le-ash-calcium powder lengezwa kakhulu, ubulukhuni be-putty powder buzokhula ngemva kokumisa.Uma i-putty powder ingenakho ukuguquguquka, izoqhekeka kalula, ikakhulukazi uma ingaphansi 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 ngemuva kokuthi amanzi engezwe 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 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-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 kwe-Around 55 degrees, uma izinga lokushisa liphakeme kancane, i-viscosity yayo izothinteka kakhulu.
