1. Izinkinga ezivamile ku-putty powder
yome ngokushesha
Lokhu ikakhulukazi kuhlobene nenani le-ash calcium powder eyengeziwe (inkulu kakhulu, inani le-ash calcium powder elisetshenziswe ku-putty formula lingancishiswa ngokufanele) kanye nezinga lokugcinwa kwamanzi le-hydroxypropyl methylcellulose (HPMC), futhi lihlobene ukoma kodonga kuhlobene.
Ukucwecwa nokugoqa
Lokhu kuhlobene nenani lokugcinwa kwamanzi, okulula ukwenzeka lapho i-viscosity ye-hydroxypropyl methylcellulose (HPMC) iphansi noma inani elingeziwe lincane.
I-De-powdering ye-interior wall putty powder
Lokhu kuhlobene nenani le-ash calcium powder (inani le-ash calcium powder ku-putty formula lincane kakhulu noma ubumsulwa be-ash calcium powder buphansi kakhulu, futhi inani le-ash calcium powder kufomula ye-putty powder kufanele libe ikhuphuke ngokufanele), futhi ihlobene nenani le-hydroxypropyl methyl Inani le-base cellulose (HPMC) lihlobene nekhwalithi, elibonakala 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.
ukubhavumula
Lokhu kuhlobene nomswakama owomile kanye nokucaba kodonga, futhi kuhlobene nokwakhiwa.
pin iphuzu
Lokhu kuhlobene ne-cellulose, enezinto ezimbi zokwakha ifilimu.Ngesikhathi esifanayo, ukungcola ku-hydroxypropyl methylcellulose (HPMC) kusabela kancane nge-ash calcium.Uma ukusabela kunzima, i-putty powder izoba sesimweni sezinsalela ze-bean curd.Ayikwazi ukufakwa odongeni, futhi ayinakho amandla ahlangene ngesikhathi esifanayo.Ngaphezu kwalokho, imikhiqizo efana ne-hydroxypropyl methylcellulose (HPMC) exutshwe neqembu le-carboxymethyl nayo ivela kulesi simo.
Kuvela izintabamlilo nezimbobo
Lokhu ngokusobala kuhlobene nokungezwani kwendawo yamanzi ye-hydroxypropyl methylcellulose (HPMC) isixazululo samanzi.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?
IHydroxypropyl methylcellulose (HPMC) isetshenziswa njenge-ejenti ejiya futhi egcina amanzi kumafutha.Ngenxa ye-thixotropy ye-hydroxypropyl methylcellulose (HPMC), i-hydroxypropyl methylcellulose ku-putty powder Ukwengezwa kwe-HPMC nakho kubangele i-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-hydroxypropyl methylcellulose (HPMC) evame ukusetshenziswa iphezulu kakhulu, futhi abanye abakhiqizi basebenzisa amayuan angama-200,000 ukwenza i-putty.I-putty ekhiqizwa ngale ndlela ine-viscosity ephezulu, ngakho izocwila lapho i-batch ikhuhla.umuzwa we.Inani elinconyiwe le-putty yezindonga zangaphakathi yi-3-5 kg, futhi i-viscosity yi-80,000-100,000.
4. Kungani uzwa sengathi i-viscosity ye-hydroxypropyl methylcellulose (HPMC) ene-viscosity efanayo 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 uma usebenzisa umkhiqizo ehlobo, noma ukwandisa inani le-hydroxypropyl methylcellulose (HPMC), nokukhetha umkhiqizo onezinga lokushisa eliphezulu lejeli.
