Ukukhiqizwa kwezimbotshana ezizilinganisayo ezisekelwe ku-gypsum kudinga ukusetshenziswa kwezinto ezihlukahlukene zokusetshenziswa, ngayinye ethinta izakhiwo ezithile zomkhiqizo wokugcina. Ingxenye ebalulekile yesimbotshana esizilinganisayo yi-cellulose ether, okuyisengezo esibalulekile.
Izimbotshana ezizilinganisayo ezisekelwe ku-Gypsum: ukubuka konke
I-self-leveling mortar iyinto yokwakha ekhethekile eyenzelwe ukusetshenziswa phansi okudinga indawo ebushelelezi neqondile. Lezi zinhlobo ze-mortar ngokuvamile zakhiwa ama-binder, ama-aggregate kanye nezinye izithako ezahlukahlukene ukuze kufezwe izici ezithile zokusebenza. I-Gypsum iyiminerali yemvelo evame ukusetshenziswa njengesihlanganisi esiyinhloko kuma-mortar azimele ngenxa yezakhiwo zayo ezihlukile, okuhlanganisa ukusetha okusheshayo kanye nokusebenza kahle kakhulu.
Izinto zokusetshenziswa zodaka oluzilinganisayo olusekelwe ku-gypsum:
1. I-Gypsum:
Umthombo: I-Gypsum iyiminerali engambiwa ngamatshe emvelo.
Umsebenzi: I-Gypsum isebenza njengesihlanganisi esiyinhloko sodaka oluzilinganisayo. Isiza ekuqineni okusheshayo nasekuthuthukisweni kwamandla.
2. Ukuhlanganiswa:
Umthombo: I-Aggregate itholakala enhlabathini yemvelo noma etsheni elichotshoziwe.
Indima: Ama-aggregates, njengesihlabathi noma amatshe amancane, ahlinzeka ngobuningi ku-mortar futhi athonya izakhiwo zawo zobuchwepheshe, okuhlanganisa amandla nokuqina.
3. I-ether ye-cellulose:
Umthombo: Ama-cellulose ether atholakala emithonjeni yemvelo ye-cellulose njenge-pulp yokhuni noma ukotini.
Umsebenzi: I-Cellulose ether isebenza njengomuguquli we-rheology kanye ne-ejenti yokugcina amanzi ukuthuthukisa ukusebenza kahle, ukunamathela kanye nokusebenza okuphelele kwe-mortar ezilinganisayo.
4. I-ejenti yokunciphisa amanzi esebenza kahle kakhulu:
Umthombo: Ama-Superplasticizer angama-polymer okwenziwa.
Umsebenzi: I-ejenti yokunciphisa amanzi esebenza kahle kakhulu ithuthukisa ukugeleza nokusebenza kahle kwe-mortar ngokunciphisa okuqukethwe kwamanzi, okwenza kube lula ukuyibeka nokuyilinganisa.
5. Umlindi:
Umthombo: Ama-retarders ngokuvamile asekelwe kumakhemikhali e-organic.
Umsebenzi: I-Retarder inganciphisa isikhathi sokusetha udoti, yandise isikhathi sokusebenza futhi ikhuthaze inqubo yokulinganisa.
6. Ukugcwalisa:
Umthombo: Ama-filler angaba emvelo (njenge-limestone) noma awenziwe ngokwenziwa.
Umsebenzi: Ama-filler afaka isandla kumthamo we-mortar, athuthukise umthamo wayo futhi athinte izakhiwo ezifana nokuxinana kanye nokuqhuba kokushisa.
7. Ifayibha:
Umthombo: Imicu ingaba yendalo (isb. imicu ye-cellulose) noma yokwenziwa (isb. imicu ye-polypropylene).
Umsebenzi: Imicu yandisa amandla okunamathela kanye nokugoba kwe-mortar futhi inciphise ingozi yokuqhekeka.
8. Amanzi:
Umthombo: Amanzi kufanele ahlanzeke futhi afanele ukuphuzwa.
Umsebenzi: Amanzi abalulekile enqubweni yokumanzisa i-plaster nezinye izithako, okufaka isandla ekuthuthukisweni kwamandla e-mortar.
Inqubo Yokukhiqiza:
Ukulungiswa kwezinto ezingavuthiwe:
I-Gypsum iyambiwa futhi icutshungulwe ukuze kutholakale impuphu ecolekile.
Iqoqo liyaqoqwa futhi lichotshozwe libe usayizi odingekayo.
Ama-ether e-cellulose akhiqizwa emithonjeni ye-cellulose ngokucubungula amakhemikhali.
hlanganisa:
I-Gypsum, i-aggregate, i-cellulose ethers, i-superplasticizer, i-retarder, ama-fillers, imicu namanzi kulinganiswa ngokunembile futhi kuxutshwe ukuze kufezwe ingxube efanayo.
I-QC:
Le nhlanganisela ihlolwa ngokulawula ikhwalithi ngokuqinile ukuqinisekisa ukuthi ihlangabezana nokuvumelana okucacisiwe, amandla kanye nezinye izindinganiso zokusebenza.
Iphakheji:
Umkhiqizo wokugcina upakishwa ezikhwameni noma kwezinye izitsha ukuze usakazwe futhi usetshenziswe ezindaweni zokwakha.
Ekuphetheni:
Ukukhiqizwa kwezimbotshana ezizilinganisayo ezisekelwe ku-gypsum kudinga ukukhethwa ngokucophelela nokuhlanganiswa kwezinto zokusetshenziswa ukuze kufezwe izakhiwo ezidingekayo. Ama-cellulose ethers adlala indima ebalulekile njengezithasiselo ezithuthukisa ukusebenza kahle, ukunamathela kanye nokusebenza kahle kwembotshana. Njengoba imboni yokwakha iqhubeka nokuthuthuka, ucwaningo kanye nentuthuko kwisayensi yezinto zokwakha kungaholela ekuthuthukisweni okwengeziwe kwezimbotshana ezizilinganisayo, okuhlanganisa ukusetshenziswa kwezithasiselo ezintsha kanye nezinto zokusetshenziswa eziqhubekayo.
