1. Impushana ye-latex ehlakazeka kabusha
Le nto yokunisela umlomo iyi-polymer ephakeme yamangqamuzana akhethekile, eyenziwa ibe yimpushana ngemva kokumiswa kwesifutho.Ngemva kokuxhumana namanzi, le powder ingaba i-emulsion futhi, futhi inezakhiwo ezifanayo njenge-emulsion.Ngemva kokuba amanzi ehwamuka, angenza ifilimu.Ifilimu inokuguquguquka okuphezulu, ukumelana nesimo sezulu esiphezulu, futhi ibonisa ukunamathela okuphezulu kuma-substrates ahlukahlukene.
Ngakho-ke, kuyimpahla eluhlaza engabalulekile odakeni oluxutshwe okomile, olungathuthukisa ukusebenza, lwandise amandla, luthuthukise ukunamathela kodaka olomile lwempuphu kuma-substrates ahlukahlukene, luthuthukise ukuguquguquka, amandla okucindezela, nokumelana nokugqoka kodaka olomile lwempuphu.Ngaphezu kwalokho, Uma ixubene ne-hydrophobic latex powder, ingenza udaka olomile lwempushana lungangeni manzi.
2. I-Cellulose
I-Cellulose ene-viscosities ehlukene inokusetshenziswa okuhlukile.I-Cellulose ingasetshenziswa ku-putty powder yezinga eliphansi ezindongeni zangaphakathi, ezingaqinisa ukugcinwa kwamanzi futhi zikhulise izinga.Iqinile kumakhemikhali, inganqanda isikhutha, inomphumela omuhle wokugcina amanzi, futhi ayiphazanyiswa izinguquko zenani le-pH.Ingasetshenziswa kusuka ku-50,000 kuya ku-200,000 viscosities.Amandla ebhondi alingana ngokuphambene, i-viscosity iphezulu, kodwa amandla mancane, ngokuvamile aphakathi kuka-50,000 no-100,000.Ikakhulukazi ukukhulisa izinga kanye nokwakhiwa kodaka lwempushana eyomile, nokunciphisa ngokufanelekile inani likasimende.
Ngaphezu kwalokho, udaka lukasimende lunesikhathi sokuqina.Ngesikhathi sokuqiniswa, ukunakekelwa okwenziwa ngesandla kuyadingeka ukuze kugcinwe kumanzi.Ngenxa yokugcinwa kwamanzi kwe-cellulose, umswakama odingekayo ukuze kuqiniswe udaka ungatholakala ekugcinweni kwamanzi kwe-cellulose, ngakho-ke ingaqiniswa ngaphandle kokugcinwa okukhethekile.
3. Lignin
Indima ye-lignin odakeni lwempuphu eyomile ukumelana nokuqhekeka.Lapho i-lignin ihlakazeka emanzini, ikhona ngesimo semicu emifushane.Ngokwesibonelo, lapho kwakhiwa izindonga ngenhlabathi ezindaweni ezifuywayo, kunezelwa utshani kakolweni notshani berayisi ukuze kuvinjelwe ukuqhekeka.Uma usebenzisa i-lignin, kungcono ukukhetha izinto ezihlanzekile ngaphandle kokungcola.Lapho uhlonza i-lignin, ungaphendula i-lignin ukuze ubone ukuthi ingabe kukhona uthuli olusele.I-powder eyengeziwe, ikhwalithi embi kakhulu.Noma faka i-lignin encane emanzini bese ubheka, kungcono ukuhlakazeka, ikhwalithi engcono, okusho ukuthi uma yengezwe ku-powder omile, kulula ukuyihlakaza futhi ngeke idale ibhola.
4. Izinto zokuhlanganisa ezingaphili
I-Ash calcium powder iyi-calcium hydroxide, into evame ukusetshenziswa ehlanganisa izinto ezingaphili.Idlala indima enkulu kakhulu ku-putty powder ukuze kuzuzwe imiphumela engangeni manzi futhi imelana namanzi.Kunezindawo eziningi ezikhiqiza i-limestone e-China, ngakho-ke ukukhiqizwa kwe-lime calcium powder kuvame kakhulu.Kodwa-ke, kwezinye izindawo, i-putty mortar eyenziwe nge-lime calcium powder ekhiqizwayo ingashisa isikhumba sezandla ngesikhathi sokwakhiwa.Ukusabela kwe-exothermic, ngakho-ke uhlaka lwe-ash calcium powder lune-alkaline kakhulu.Uma uhlaka luba lukhudlwana, luzinza kakhulu, futhi kulula ukuqhekeka lapho luklwejwa odongeni.Sifuna ukwaziswa okunempushana yomlotha we-calcium ezinzile, enombhalo omncane, ubumhlophe obuhle, futhi ayigudli izandla.
