Udaka oluxutshwe okomile luyinhlanganisela yezinto zikasimende (usimende, umlotha wempukane, impushana ye-slag, njll.), ama-aggregate akhethekile ahlelwe kahle (isihlabathi se-quartz, i-corundum, njll., futhi ngezinye izikhathi kudinga ama-Granules alula, i-perlite eyandisiwe, i-vermiculite enwetshiwe, njll. ) kanye nezixube zixutshwa ngokufanayo ngesilinganiso esithile, bese zipakishwa ezikhwameni, emiphongolweni noma zinikezwe ngobuningi esimweni sempushana esomile njengempahla yokwakha.
Kunezinhlobo eziningi zodaka lwezentengiselwano, okuhlanganisa udaka oluyimpushana olomile lokwakha amatshe, udaka oluyimpushana olomile lokuplasta, udaka olomile lwempushana yomhlabathi, udaka olukhethekile lwempushana olomile lokuvikela amanzi, ukulondoloza ukushisa nezinye izinjongo.Ukufingqa, udaka oluxutshwe okomile lungahlukaniswa lube udaka olujwayelekile oluxutshwe okomile (ukwakha, ukupulasitela kanye nodaka oluxutshwe nomhlabathi owomile) kanye nodaka olukhethekile oluxutshwe okomile.Udaka olukhethekile oluxutshwe okomile luhlanganisa: udaka oluzilinganisa ngokwalo, impahla yaphansi engagugi, i-ejenti ye-caulking ye-inorganic, udaka olungenamanzi, udaka olunamekelwayo lwe-resin, izinto zokuvikela ukhonkolo ezingaphezulu, udaka olukhonkolo olunemibala, njll.
Ngakho-ke izinsimbi eziningi ezixutshwe okomile zidinga izingxube zezinhlobonhlobo ezahlukene kanye nezindlela ezihlukahlukene zokusebenza okufanele zenziwe ngenani elikhulu lokuhlola.Uma kuqhathaniswa ne-admixtures yendabuko kakhonkolo, i-admixtures yodaka oluxubekile ingasetshenziswa kuphela kwifomu yempushana, futhi okwesibili, iyancibilika emanzini abandayo, noma incibilike kancane kancane ngaphansi kwesenzo se-alkalinity ukuze yenze umphumela wayo ofanele.
I-latex powder ephinda ihlakazeka ngokuvamile iyimpushana emhlophe ene-fluidity eyomile, enokuqukethwe komlotha okungaba ngu-12%, futhi okuqukethwe komlotha ikakhulukazi kuvela kumenzeli wokukhulula.Usayizi wezinhlayiyana ojwayelekile we-polymer powder cishe u-0.08mm.Yiqiniso, lokhu ubukhulu be-emulsion particle aggregate.Ngemuva kokusabalalisa kabusha emanzini, usayizi wezinhlayiyana ojwayelekile wezinhlayiyana ze-emulsion ngu-1 ~ 5um.Ubukhulu bezinhlayiya ezijwayelekile zezinhlayiya ze-emulsion ezisetshenziswe ngokuqondile ngendlela ye-emulsion ngokuvamile cishe ngo-0.2um, ngakho-ke ubukhulu bezinhlayiyana ze-emulsion ezakhiwe yi-polymer powder bukhulu kakhulu.Umsebenzi oyinhloko ukukhulisa amandla okubopha odaka, ukuthuthukisa ukuqina kwawo, ukuguquguquka, ukumelana nokuqhekeka nokungangenisi, kanye nokwenza ngcono ukugcinwa kwamanzi nokuzinza kodaka.
I-polymer redispersible polymer powder okwamanje esetshenziswa odakeni lwempushana eyomile ikakhulukazi ihlanganisa lezi zinhlobo ezilandelayo:
(1) i-styrene-butadiene copolymer;
(2) I-copolymer ye-styrene-acrylic acid;
(3) i-vinyl acetate homopolymer;
(4) i-polyacrylate homopolymer;
(5) I-styrene acetate copolymer;
(6) I-Vinyl acetate-ethylene copolymer, njll., iningi lazo okuyi-vinyl acetate-ethylene copolymer powder.
