1 Izinkinga ezijwayelekile ku-wall putty powder:
(1) 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.
(2) Hlanza futhi ugoqe.
Lokhu kuhlobene nesilinganiso sokugcinwa kwamanzi, okulula ukwenzeka lapho i-viscosity ye-cellulose iphansi noma inani lokwengeza lincane.
(3) Ukususwa kwempuphu ye-putty yangaphakathi yodonga.
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 ngokufanele), 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, okubangelwa.
(4) Amabhamuza.
Lokhu kuhlobene nomswakama owomile kanye nokucaba kodonga, futhi kuhlobene nokwakhiwa.
(5) 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 ayinawo amandla ahlangene ngesikhathi esifanayo. Ngaphezu kwalokho, lesi simo siphinde senzeka ngemikhiqizo efana namaqembu e-carboxyl angezwe ku-cellulose.
(6) Kuvela izimbobo nezimbobo zentabamlilo.
Lokhu ngokusobala kuhlobene nokushuba kwesimo samanzi sesisombululo samanzi se-hydroxypropyl methylcellulose. Ukungezwani kwetafula lamanzi kwesisombululo samanzi se-hydroxyethyl akubonakali. Kungaba kuhle ukwenza ukwelashwa kokuqeda.
(7) Ngemva kokuba 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, eyethulwa ngaphambili.
2 Kungani impushana 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 Kungani i-putty inzima uma kuqhathaniswa nenqubo yokukhuhla?
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-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 ukwandisa inani le-cellulose, nokukhetha umkhiqizo onokushisa kwe-gel ephakeme. Zama ukungasebenzisi i-methyl cellulose ehlobo, izinga lokushisa layo lejeli lingama-degree angama-55, uma izinga lokushisa liphakeme kancane, i-viscosity yayo izothinteka kakhulu.
