Ukukhiqizwa kwe-gypsum-based self-leveling mortars kudinga ukusetshenziswa kwezinto ezihlukahlukene zokusetshenziswa, ngayinye ethinta izici ezithile zomkhiqizo wokugcina. Ingxenye ebalulekile yodaka lokuzilinganisa i-cellulose ether, okuyisengezo esibalulekile.
Izinsimbi zokuzilinganisa ezisekelwe e-Gypsum: ukubuka konke
Udaka oluzilinganisa luyimpahla yokwakha eyisipesheli eyenzelwe izinhlelo zokubeka phansi ezidinga indawo ebushelelezi, eneleveli. Lawa ma-mortar ngokuvamile ahlanganisa ama-binder, ama-aggregate nezithasiselo ezihlukahlukene ukuze kuzuzwe izici ezithile zokusebenza. I-Gypsum iyiminerali yemvelo evame ukusetshenziswa njengesibopho esiyinhloko osikeni oluzilinganisa ngenxa yezakhiwo zayo ezihlukile, okuhlanganisa ukusetha okusheshayo nokusebenza okuhle kakhulu.
Izinto zokusetshenziswa zodaka lokuzilinganisa olususelwa ku-gypsum:
1. I-Gypsum:
Umthombo: I-Gypsum iyiminerali engenziwa emigodini yemvelo.
Umsebenzi: I-Gypsum isebenza njengesibophezelo esikhulu sodaka oluzilinganisa ngokwalo. Isiza ekuqiniseni ngokushesha nasekuthuthukiseni amandla.
2. Ukuhlanganisa:
Umthombo: I-aggregate isuselwa ku-sediments yemvelo noma itshe elichotshoziwe.
Iqhaza: Ama-aggregate, njengesihlabathi noma amatshe amahle, ahlinzeka ngobuningi othulini futhi abe nomthelela emikhiqizweni yawo, okuhlanganisa amandla nokuqina.
3. I-cellulose ether:
Umthombo: Ama-cellulose ether athathwe emithonjeni ye-cellulose yemvelo efana ne-wood pulp noma ukotini.
Umsebenzi: I-Cellulose ether isebenza njengesilungisi se-rheology kanye ne-ejenti egcina amanzi ukuze kuthuthukiswe ukusebenza, ukunamathela kanye nokusebenza kukonke kodaka oluzilinganisa.
4. I-ejenti yokunciphisa amanzi esebenza kahle kakhulu:
Umthombo: Ama-Superplasticizers angama-polymer okwenziwa.
Umsebenzi: I-ejenti yokunciphisa amanzi esebenza kahle kakhulu ithuthukisa uketshezi nokusebenza kodaka ngokunciphisa okuqukethwe kwamanzi, okwenza kube lula ukuyibeka kanye neleveli.
5. Obuyisela emuva:
Umthombo: Ama-retarders ngokuvamile asekelwe kuma-organic compounds.
Umsebenzi: I-retarder inganciphisa isikhathi sokumisa udaka, yandise isikhathi sokusebenza futhi ikhuthaze inqubo yokulinganisa.
6. Ukugcwalisa:
Umthombo: Izigcwalisi zingaba zemvelo (njenge-limestone) noma zokwenziwa.
Umsebenzi: Izigcwalisi zifaka isandla kumthamo wodaka, zikhuphule umthamo wazo futhi zithinte izakhiwo ezinjengokuminyana kanye nokuhamba kwe-thermal.
7. Ifayibha:
Umthombo: Imicu ingaba yimvelo (isb. imicu ye-cellulose) noma yokwenziwa (isb. imicu ye-polypropylene).
Umsebenzi: Amafayibha akhulisa amandla okuqina kanye nokuguquguquka kodaka futhi anciphisa ingozi yokuqhekeka.
8. Amanzi:
Umthombo: Amanzi kufanele ahlanzeke futhi alungele ukuphuzwa.
Umsebenzi: Amanzi abalulekile enqubweni ye-hydration ye-plaster nezinye izithako, okunomthelela ekuthuthukiseni amandla odaka.
Inqubo Yokukhiqiza:
Ukulungiswa kwezinto ezingavuthiwe:
I-Gypsum iyambiwa futhi icutshungulwe ukuze kutholakale impushana ecolekile.
I-aggregate iyaqoqwa futhi ichotshozwe kusayizi odingekayo.
Ama-cellulose ether akhiqizwa emithonjeni ye-cellulose ngokucubungula amakhemikhali.
hlanganisa:
I-Gypsum, i-aggregate, i-cellulose ethers, i-superplasticizer, i-retarder, izigcwalisi, imicu kanye namanzi kukalwa ngokunembile futhi kuxutshwe ukuze kuzuzwe ingxube ye-homogeneous.
I-QC:
Le nhlanganisela ibhekana nokuhlolwa kokulawulwa kwekhwalithi okuqinile ukuze kuqinisekiswe ukuthi ihlangabezana nokuvumelana okucacisiwe, amandla namanye amazinga okusebenza.
Iphakheji:
Umkhiqizo wokugcina upakishwa ezikhwameni noma kwezinye iziqukathi ukuze zihanjiswe futhi zisetshenziswe ezindaweni zokwakha.
Ekuphetheni:
Ukukhiqizwa kwe-gypsum-based self-leveling mortars kudinga ukukhethwa ngokucophelela kanye nenhlanganisela yezinto ezingavuthiwe ukuze kuzuzwe izakhiwo ezidingekayo. Ama-cellulose ether adlala indima ebalulekile njengezithasiselo ezithuthukisa ukusebenza, ukunamathela kanye nokusebenza kukonke kodaka. Njengoba imboni yezokwakha iqhubeka nokuvela, ucwaningo nokuthuthukiswa kwesayensi yezinto ezibonakalayo kungase kuholele ekuthuthukisweni okwengeziwe kodaka oluzilinganisa ngokwalo, okuhlanganisa nokusetshenziswa kwezithasiselo ezintsha nezinto zokusetshenziswa ezisimeme.
