yome ngokushesha
Lokhu ikakhulukazi ngenxa yokwengezwa ngokweqile kwe-ash calcium powder (inani le-ash calcium powder elisetshenziswe ku-putty formula lingancishiswa ngokufanele) lihlobene nenani lokugcinwa kwamanzi e-hydroxypropyl methylcellulose, futhi lihlobene nokomisa kodonga. .
Ukucwecwa nokugoqa
Lokhu kuhlobene nokuqukethwe okuphezulu kwe-ash calcium noma izinga eliphansi lokugcina amanzi e-hydroxypropyl methylcellulose, okuvame ukwenzeka lapho i-viscosity ye-cellulose iphansi noma inani elingeziwe 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 ngendlela efanele), futhi kuhlobene nokwengezwa kwe-cellulose Kukhona ubudlelwano phakathi kobuningi nekhwalithi, okubonakala ngenani lokugcinwa kwamanzi omkhiqizo. Izinga lokugcinwa kwamanzi liphansi, futhi isikhathi sokuphendula se-ash calcium powder (i-calcium oxide emlotheni we-calcium powder ayiguqulwa ngokugcwele ku-calcium hydroxide) ayanele, okubangelwa.
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-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 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. Kuphinde kuhlobane nokwengezwa ngokweqile kwe-hydroxypropyl methylcellulose.
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.
Kungani i-putty powder iba mncane ngemva kokungeza amanzi?
I-Cellulose isetshenziswa njenge-thickener kanye ne-ejenti 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.
Yisiphi isizathu esenza ukuthi i-putty ibe nzima kakhulu 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.
Kungani i-viscosity ye-cellulose izizwa ihlukile uma usebenzisa i-viscosity cellulose efanayo 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.
