Izithasiselo eziguquliwe njengezithasiselo ze-mortar ezixutshwe ngomumo, ama-ether e-cellulose, abalawuli be-coagulation, i-latex powder ephinde ihlakazeke, ama-air-entraining agents, ama-ejenti okuqina okuqala, ama-water reducers, njll., anezelwa ngokwezidingo zephrojekthi, athuthukisa kakhulu ukusebenza kwe-mortar ezixutshwe ngomumo. Izakhiwo zomzimba nezemishini.
1. Isithasiselo sikadaka esixutshwe ngomuthi
I-anionic surfactant equkethwe ku-additive mortar exutshwe ngomucu kuphrojekthi ingenza izinhlayiya zesamente zihlakazeke zodwa, zikhulule amanzi akhululekile ahlanganiswe yi-aggregate yesimende, zisakaze ngokugcwele isisindo sesamente esihlanganisiwe, futhi zisigcwalise ngokuphelele ukuze kufezwe isakhiwo esiqinile futhi kwandiswe ubuningi be-mortar. Amandla, ukuthuthukisa ukungenwa kwamanzi, ukumelana nokuqhekeka nokuqina. I-mortar exutshwe nezithasiselo ze-mortar ezixutshwe ngomucu inamandla okusebenza kahle, izinga eliphezulu lokugcina amanzi, amandla aqinile okuhlangana, ayinabo ubuthi, ayinangozi, iphephile futhi inobungani nemvelo ngesikhathi sokusebenza. Ifanele ukukhiqizwa kwe-marshmallow evamile, i-plastering, i-ground, kanye ne-mortar engangeni manzi ezimbonini ze-mortar ezixutshwe ngomucu. Isetshenziselwa ukwakhiwa kwe-marshmallow kanye nokwakhiwa kwezitini zobumba zekhonkrithi, izitini ze-ceramsite, izitini ezingenalutho, amabhlogo ekhonkrithi, izitini ezingashiswanga ezakhiweni ezahlukene zezimboni nezomphakathi. Ukwakhiwa kwe-plastering yodonga yangaphakathi neyangaphandle, i-plastering yodonga lwekhonkrithi, i-floor and roof leveling, i-mortar engangeni manzi, njll.
2. I-ether ye-cellulose
Ku-mortar exutshwe kakade, i-cellulose ether iyisengezo esiyinhloko esingathuthukisa kakhulu ukusebenza kwe-mortar emanzi futhi sithinte ukusebenza kokwakhiwa kwe-mortar. Ukukhetha okunengqondo kwama-ether e-cellulose ezinhlobo ezahlukene, ukuqina okuhlukile, ubukhulu bezinhlayiya ezahlukene, amazinga ahlukene e-viscosity kanye namanani engeziwe kuzoba nomthelela omuhle ekuthuthukisweni kokusebenza kwe-mortar eyomile.
Ukukhiqizwa kwe-cellulose ether kwenziwa kakhulu ngemicu yemvelo ngokuncibilika kwe-alkali, ukusabela kokuxhunyelelwa (i-etherification), ukuwasha, ukomisa, ukucwiliswa kanye nezinye izinqubo. Ekukhiqizweni kwezinto zokwakha, ikakhulukazi udaka oluyimpuphu eyomile, i-cellulose ether idlala indima engenakuphindwa, ikakhulukazi ekukhiqizweni kodaka olukhethekile (udaka oluguquliwe), luyinto ebalulekile futhi ebalulekile. I-cellulose ether idlala indima yokugcina amanzi, ukuqina, ukubambezela amandla okumunca usimende, kanye nokuthuthukisa ukusebenza kokwakha. Amandla okugcina amanzi amahle enza ukumunca usimende kuphelele, kungathuthukisa i-viscosity emanzi yodaka olumanzi, kwandise amandla okubopha kodaka, futhi kulungise isikhathi. Ukwengeza i-cellulose ether kodaka olufutha ngomshini kungathuthukisa ukusebenza kokufutha noma kokupompa kanye namandla esakhiwo sodaka. Ngakho-ke, i-cellulose ether isetshenziswa kabanzi njengesithasiselo esibalulekile kudaka oluxutshwe ngomumo. Ama-cellulose ether asetshenziswa kudaka oluxutshwe ngomumo ikakhulukazi yi-methyl hydroxyethyl cellulose ether kanye ne-methyl hydroxypropyl cellulose ether., athatha ngaphezu kwama-90% wesabelo semakethe.
3. Impuphu ye-latex ephinde ihlakazeke
Impuphu ye-latex ephinde ihlakazeke iyi-resin ye-thermoplastic ewumpuphu etholakala ngokufutha nge-spray kanye nokucutshungulwa okulandelayo kwe-polymer emulsion. Isetshenziswa kakhulu ekwakheni, ikakhulukazi udoti wempuphu owomile ukwandisa ukuhlangana, ukuhlangana kanye nokuguquguquka.
Indima yempuphu ye-latex ephinde ihlakazeke ku-mortar: i-latex powder ephinde ihlakazeke yakha ifilimu ngemva kokuhlakazeka futhi isebenza njenge-glue yesibili yokuthuthukisa ukunamathela; i-colloid evikelayo imuncwa uhlelo lwe-mortar futhi ngeke ibhujiswe ngamanzi ngemva kokwakheka kwefilimu Noma ukuhlakazeka okubili; i-resin ye-polymer eyakha ifilimu isatshalaliswa kulo lonke uhlelo lwe-mortar njengento yokuqinisa, ngaleyo ndlela yandisa ukuhlangana kwe-mortar.
Impuphu ye-latex ephinde ihlakazeke ku-mortar emanzi ingathuthukisa ukusebenza kokwakhiwa, ithuthukise ukusebenza kokugeleza, yandise ukumelana kwe-thixotropy kanye nokuwa, ithuthukise ukuhlangana, yandise isikhathi sokuvula, ithuthukise ukugcinwa kwamanzi, njll. Ngemva kokuba i-mortar ipholile, ingathuthukisa amandla okudonsa. Amandla okudonsa, amandla okugoba athuthukisiwe, i-modulus encishisiwe yokunwebeka, ukuguquguquka okuthuthukisiwe, ukuqina kwezinto, ukumelana nokuguguleka okuthuthukisiwe, amandla okubambisana athuthukisiwe, ukujula kwe-carbonization okuncishisiwe, ukumuncwa kwamanzi okuncishisiwe kwezinto, futhi yenze izinto zibe nokumelana namanzi okuhle kakhulu. Imiphumela esekelwe emanzini neminye.
4. I-ejenti yokufaka umoya
I-air-entraining agent, eyaziwa nangokuthi i-air-entraining agent, ibhekisela ekungenisweni kwenani elikhulu lama-micro-bubbles asatshalaliswa ngokulinganayo ngesikhathi senqubo yokuxuba i-mortar, okunganciphisa ukucindezeleka kwamanzi ku-mortar, okuholela ekuhlakazekeni okungcono kanye nokuncipha kwengxube ye-mortar. Ukopha, ukuhlukanisa izithasiselo. Ngaphezu kwalokho, ukungeniswa kwama-bubbles omoya amahle futhi azinzile nakho kuthuthukisa ukusebenza kokwakhiwa. Inani lomoya ongeniswayo lincike ohlotsheni lwe-mortar kanye nemishini yokuxuba esetshenziswayo.
Nakuba inani le-ejenti yokungenisa umoya lincane kakhulu, i-ejenti yokungenisa umoya inethonya elikhulu ekusebenzeni kwe-mortar exutshwe ngomumo, engathuthukisa ngempumelelo ukusebenza kwe-mortar exutshwe ngomumo, ithuthukise ukungangeni kwamanzi kanye nokumelana neqhwa kwe-mortar, futhi inciphise ukuminyana kwe-mortar, yonge izinto futhi yandise indawo yokwakha, kodwa ukwengezwa kwe-ejenti yokungenisa umoya kuzonciphisa amandla e-mortar, ikakhulukazi i-mortar ecindezelayo. Ukuqina kobudlelwano ukunquma umthamo ofanele.
5. I-ejenti yamandla okuqala
I-ejenti yamandla okuqala iyisengezo esingasheshisa ukuthuthukiswa kwamandla okuqala kwe-mortar, iningi lawo elingama-electrolyte angaphili, kanti ambalwa angama-organic compounds.
I-accelerator ye-mortar exutshwe ngomumo iyadingeka ukuze ibe yimpuphu futhi yome. I-Calcium formate iyona esetshenziswa kakhulu ku-mortar exutshwe ngomumo. I-Calcium formate ingathuthukisa amandla okuqala e-mortar, futhi isheshise ukumuncwa kwe-triccalcium silicate, okunganciphisa amanzi ngezinga elithile. Ngaphezu kwalokho, izakhiwo zomzimba ze-calcium formate zizinzile ekushiseni kwegumbi. Akulula ukuhlangana futhi ifaneleka kakhulu ukusetshenziswa ku-mortar e-dry powder.
6. Isinciphisi samanzi
I-ejenti yokunciphisa amanzi ibhekisela esithasiselweni esinganciphisa inani lamanzi axutshwayo ngaphansi kwesimo sokugcina ukuqina kodaka kufana. I-water reducer ngokuvamile iyi-surfactant, engahlukaniswa ibe yi-water reducers ejwayelekile, i-water reducers esebenza kahle kakhulu, i-early strength water reducers, i-water reducers encishisiwe, i-water reducers esebenza kahle kakhulu kanye ne-induced water reducers ngokwemisebenzi yayo.
Isinciphisi samanzi esisetshenziselwa udaka oluxutshwe ngomucu siyadingeka ukuthi sibe yimpuphu futhi somile. Isinciphisi samanzi esinjalo singasakazwa ngokulinganayo kudaka oluxutshwe ngomucu olumile ngaphandle kokunciphisa isikhathi sokuphila kweshelufu lodaka oluxutshwe ngomucu. Njengamanje, ukusetshenziswa kwe-ejenti yokunciphisa amanzi kudaka oluxutshwe ngomucu ngokuvamile ku-cement self-leveling, gypsum self-leveling, plastering udaka, udaka olungangeni manzi, i-putty, njll. Ukukhetha i-ejenti yokunciphisa amanzi kuncike ezintweni zokusetshenziswa ezahlukene kanye nezakhiwo ezahlukene zedaka. Khetha.
