Indlela Izithako Zodaka Ezixube Kahle Ziluthuthukisa Kanjani Ukuhlaziywa Kokusebenza Kodaka

01. Isithasiselo sodaka esixubekile

I-anionic surfactant equkethwe esenzweni sikasimende esixutshwe ngomumo kule phrojekthi ingenza izinhlayiya zikasimende zihlakazeke zodwa, ikhulule amanzi amahhala ambozwe iqoqo likasimende, ihlakaze ngokugcwele isisindo sikasimende esihlanganisiwe, futhi iwufake amanzi ngokuphelele ukuze uzuze isakhiwo esihlangene futhi. ukwandisa ukuminyana kodaka.Amandla, athuthukise ukungagxili, ukumelana nokuqhekeka nokuqina.Udaka oluxutshwe nezithako zodaka oseluvele luxubile lukwazi ukusebenza kahle, izinga eliphezulu lokugcinwa kwamanzi, amandla aqinile okuhlangana, angenabuthi, awanangozi, aphephile futhi anobungani nemvelo ngesikhathi sokusebenza.Ilungele ukukhiqizwa kwamatshe ajwayelekile, ukuplasta, umhlabathi, nodaka olungangeni manzi emafektri odaka asevele axubene.Isetshenziselwa ukwakha nokwakhiwa kwezitini zobumba zikakhonkolo, izitini ze-ceramsite, izitini ezingenalutho, amabhlogo kakhonkolo, izitini ezingashiswanga ezakhiweni ezihlukahlukene zezimboni kanye nezomphakathi.Ukwakhiwa kokuplasta odongeni lwangaphakathi nangaphandle, ukuplasta kwezindonga zikakhonkolo, ukulinganisa phansi nophahla, udaka olungangeni manzi, njll.

02. Cellulose ether

Odakeni oseluxubile, i-cellulose ether iyisengezo esiyinhloko esingathuthukisa kakhulu ukusebenza kodaka olumanzi futhi sithinte ukusebenza kokwakhiwa kodaka.Ukukhethwa okunengqondo kwama-cellulose ethers ezinhlobonhlobo ezahlukene, ama-viscosity ahlukene, ubukhulu bezinhlayiya ezihlukahlukene, amazinga ahlukene e-viscosity namanani angeziwe azoba nomthelela omuhle ekuthuthukiseni ukusebenza kwe-powder mortar.

Ukukhiqizwa kwe-cellulose ether kwenziwa ikakhulukazi ngemicu yemvelo ngokusebenzisa ukuchithwa kwe-alkali, ukusabela ngokuxhunyelelwa (i-etherification), ukugeza, ukomisa, ukucwiliswa emanzini nezinye izinqubo.Ekukhiqizeni izinto zokwakha, ikakhulukazi udaka lwempuphu eyomile, i-cellulose ether idlala indima engenakushintshwa, ikakhulukazi ekukhiqizeni udaka olukhethekile (udaka oluguquliwe), luyingxenye ebalulekile futhi ebalulekile.I-Cellulose ether idlala indima yokugcina amanzi, ukuqina, ukubambezela amandla okufaka usimende, kanye nokwenza ngcono ukusebenza komsebenzi wokwakha.Umthamo omuhle wokugcina amanzi wenza ukugeleza kukasimende kuphelele, kungathuthukisa i-viscosity emanzi yodaka olumanzi, kukhuphule amandla okubopha odaka, futhi kulungise isikhathi.Ukwengeza i-cellulose ether kudaka lokufafaza lomshini kungathuthukisa ukusebenza kokufuthwa noma ukumpompa namandla esakhiwo sodaka.Ngakho-ke, i-cellulose ether isetshenziswa kabanzi njengesengezo esibalulekile odakeni oluxubile.Ama-cellulose ether asetshenziswa odakeni oseluxutshiwe ikakhulukazi i-methyl hydroxyethyl cellulose ether ne-methyl hydroxypropyl cellulose ether., bathatha ngaphezu kuka-90% wesabelo semakethe.

03. Impushana ye-latex ehlakazeka kabusha

I-latex powder ephinda ihlakazeka iyi-powdery thermoplastic resin etholwe ngokumiswa kwesifutho nokucutshungulwa okulandelayo kwe-polymer emulsion.Isetshenziswa kakhulu ekwakhiweni, ikakhulukazi udaka lwempushana eyomile ukuze kwandiswe ukuhlangana, ukubumbana kanye nokuguquguquka.

Indima ye-latex powder ehlakazeka kabusha odakeni: i-latex powder ephinda ihlakazeka yakha ifilimu ngemva kokuhlakazeka futhi isebenza njenge-adhesive yesibili yokuthuthukisa ukunamathela;i-colloid evikelayo imuncwa uhlelo lodaka futhi ngeke ichithwe ngamanzi ngemva kokwakhiwa kwefilimu Noma ama-dispersions amabili;i-polymer resin eyenza ifilimu isakazwa kulo lonke uhlelo lodaka njengento yokuqinisa, ngaleyo ndlela ikhulise ukuhlangana kodaka.

I-latex powder ehlakazeka kabusha odakeni olumanzi ingathuthukisa ukusebenza kokwakhiwa, ithuthukise ukusebenza kokugeleza, ikhuphule ukumelana ne-thixotropy kanye ne-sag, ithuthukise ukuhlangana, yelule isikhathi esivulekile, ithuthukise ukugcinwa kwamanzi, njll. Ngemva kokuba udaka seselaphekile, lungathuthukisa amandla aqinile.Amandla aqinile, amandla okugoba athuthukisiwe, i-modulus enwebekayo encishisiwe, ukukhubazeka okuthuthukisiwe, ukukhubazeka okuthuthukisiwe, ukuhlangana kwezinto ezibonakalayo, ukumelana nokugqokwa okuthuthukisiwe, amandla okuhlangana athuthukisiwe, ukujula kwe-carbonization okuncishisiwe, ukumuncwa kwamanzi okuncishisiwe, futhi kwenza izinto ezisetshenziswayo zibe nokuxosha amanzi okuhle kakhulu Okusekelwe emanzini nokunye. imiphumela.

04. I-ejenti yokungenisa umoya

I-air-entraining agent, eyaziwa nangokuthi i-air-entraining agent, ibhekisela ekwethulweni kwenani elikhulu lamabhamuza amancane asatshalaliswa ngokufanayo ngesikhathi sokuxuba udaka, okunganciphisa ukushuba kwesimo samanzi odaka, okuholela ekuhlakazweni okungcono. kanye nengxube yodaka encishisiwe.Ukopha, ukuhlukanisa izithasiselo.Ngaphezu kwalokho, ukwethulwa kwamabhamuza omoya amahle futhi azinzile nakho kuthuthukisa ukusebenza kokwakhiwa.Inani lomoya owethulwe lincike ohlotsheni lodaka kanye nemishini yokuxuba esetshenzisiwe.

Nakuba inani le-ejenti yokungenisa umoya lincane kakhulu, i-ejenti yokungenisa umoya inethonya elikhulu ekusebenzeni kodaka oluxutshwe ngomumo, olungathuthukisa ngokuphumelelayo ukusebenza kodaka oluxutshwe ngomumo, luthuthukise ukungakwazi ukungena kanye nokumelana nesithwathwa sodaka. , futhi unciphise ukuminyana kodaka , gcina izinto zokwakha futhi ukwandise indawo yokwakha, kodwa ukungezwa kwe-ejenti yokungenisa umoya kuzonciphisa amandla odaka, ikakhulukazi udaka olucindezelayo.Ukuqina kokuxhumana ukuze kunqunywe umthamo olungile.

05. I-ejenti yamandla yangaphambi kwesikhathi

I-ejenti yamandla yakuqala iyisengezo esingasheshisa ukuthuthukiswa kwamandla okuqala odaka, iningi lawo okungama-electrolyte angaphili, kanti ambalwa angama-organic compounds.

I-accelerator yodaka oluxutshwe ngomumo iyadingeka ukuze ibe yimpuphu futhi yome.I-calcium formate isetshenziswa kakhulu odakeni oseluvele luxubene.I-calcium formate ingathuthukisa amandla okuqala odaka, futhi isheshise ukugeleza kwe-tricalcium silicate, enganciphisa amanzi ngezinga elithile.Ngaphezu kwalokho, izakhiwo ezingokomzimba ze-calcium formate zizinzile ezingeni lokushisa elivamile.Akulula ukuhlanganisa i-agglomerate futhi ifaneleka kakhulu ukusetshenziswa ku-powder mortar omile.

06. Isinciphisi samanzi

I-ejenti yokunciphisa amanzi ibhekisela ku-additive enganciphisa inani lokuxuba amanzi ngaphansi kwesimo sokugcina ukuvumelana kodaka ngokuyisisekelo okufanayo.Isinciphisi samanzi ngokuvamile siyi-surfactant, esingahlukaniswa sibe izinciphisi zamanzi ezivamile, izinciphisi zamanzi ezisebenza kahle kakhulu, izinciphisi zamanzi zangaphambi kwesikhathi, izinciphisi zamanzi ezinesikhathi eside, izinciphisi zamanzi ezingasebenzi kahle nezinciphisa umoya ezifaka umoya ngokwemisebenzi yazo.Izinhlobonhlobo.

Isinciphisi samanzi esisetshenziselwa udaka oseluxubile kudingeka sibe yimpuphu futhi some.Isinciphisi samanzi esinjalo singahlakazwa ngokulinganayo odakeni lwempuphu eyomile ngaphandle kokunciphisa impilo yeshalofu yodaka oluxutshwe ngomumo.Njengamanje, ukusetshenziswa kwe-ejenti yokunciphisa amanzi odakeni oluxubekile ngokuvamile ku-simende self-leveling, i-gypsum self-leveling, i-plastering mortar, udaka olungangeni manzi, i-putty, njll. izakhiwo zodaka.Khetha.
