I-Hydroxypropyl methylcellulose (HPMC)Ngokuyinhloko idlala indima yokugcinwa kwamanzi, ukuqina kanye nokwenza ngcono ukusebenza kokwakha ku-CEMM, i-Gypsum nezinye izinto zempuphu. Ukusebenza okuhle kakhulu kokugcina amanzi kungavimba ngempumelelo i-powder ekusomisweni nasekuqhekekeni ngenxa yokulahleka kwamanzi ngokweqile, futhi wenze i-powder ibe nesikhathi esijana sokwakhiwa.
Yenza ukukhetha kwezinto zokwakha i-cementionale, ama-aggregates, ama-aggregates, ama-ejenti okugcina amanzi, ama-linder asebenza ngokusebenza, kepha ukusebenza kwawo kwe-gyp kuncipha ngokushesha ngaphansi kwesimo sokutholwa komswakama kanye nokumuncwa kwamanzi. Amandla okubopha okuhlosiwe kodaka oluphambayo kufanele ancishiswe ungqimba ngesendlalelo, okungukuthi, amandla obusemboni phakathi kwe-warwer yodaka kanye ne-interface yokwelashwa ≥ amandla agqinsi aphakathi kwe-fortar
Umgomo ofanele we-hydration ka usimende wodaka esisekelweni ukuthi umkhiqizo we-cyment hydration umunca amanzi kanye nesisekelo, angena esisekelweni, futhi akha "okusebenzayo" ukuze afeze amandla adingekayo ebhondi. Ukunisela ngqo ebusweni besisekelo kuzodala ukuhlakazeka okukhulu ekutholeni kwamanzi kwesisekelo ngenxa yokungafani kokushisa, isikhathi sokunisela kanye nokunisela. Isisekelo sinokutholwa kwamanzi okuncane futhi sizoqhubeka nokudonsa amanzi odongeni. Ngaphambi kokuthi i-Conment Hydration iqhubeka, amanzi amunwa, okuthinta i-hydration yesisikile kanye nokungena kwemikhiqizo ye-hydration kwi-matrix; Isisekelo sinokuthathwa kwamanzi okukhulu, namanzi asosimende ageleza ezansi. Ijubane lokufuduka eliphakathi lihamba kancane, futhi noma ungqimba olunothile lwamanzi kwakheka phakathi kodaka kanye ne-matrix, okubuye kuthinta amandla e-bond. Ngakho-ke, ukusebenzisa indlela ejwayelekile yokunisela izisekelo ngeke kuhluleke kuphela ukuxazulula inkinga yokufakwa kwamanzi okuphezulu kwesisekelo sodonga, kepha kuzothinta amandla okubopha phakathi kodaka kanye nesisekelo, okuholela ekuhlolweni nasekuhlanganeni.
Umphumela we-cellulose ether ngamandla acindezelayo futhi agunda amandla kasimende kasimende.
Ngokungezwa kweI-Cellulose Ether, Amandla acindezelayo futhi ashubile anciphe, ngoba i-cellulose ether imunca amanzi futhi inyusa impama.
Ukusebenza kweBonding namandla eBonding kuncike ekutheni ngabe interface phakathi kodaka kanye nokuqukethwe kwesisekelo kungahle kube kangako futhi kufinyeleleke ngempumelelo "ukuxhumana okuphambili" isikhathi eside.
Izici ezithinta amandla ebhondi zifaka:
1. Izici zokufakwa kwamanzi kanye nokuqina kwesibonisi se-substrate.
2
3. Amathuluzi wokwakha, izindlela zokwakha kanye nemvelo yokwakha.
Ngoba ungqimba lwesisekelo lokwakhiwa kodaka kunomunwe othile wamanzi, ngemuva kokuthi ungqimba lwesisekelo amunca amanzi ngodaka, futhi ezimweni ezingezinyokuwo azowohloka, okubangelwa amandla okuthi udaka olungaphansi, okubangelwa amandla okuthi udaka phakathi kodaka oluhlaza okwesibhakabhaka luzokwehla, okwenza udaka lube luhlaza luwe. Isixazululo sendabuko kulezi zinkinga ukunisela isisekelo, kepha akunakwenzeka ukuqinisekisa ukuthi isisekelo siyanyiswa ngokulinganayo.
