I-HPMC (CAS:9004-65-3), njengesengezo esisetshenziswa kabanzi emkhakheni wezinto zokwakha, isetshenziselwa kakhulu ukugcina amanzi, ukujiya kanye nokwenza ngcono ukusebenza komkhiqizo oqediwe.Izinga lokugcinwa kwamanzi lingenye yezinkomba eziyinhloko uma khetha i-HPMC yekhwalithi ephezulu, ngakho-ke ake sibhekisise izici ezithinta izinga lokugcinwa kwamanzi le-HPMC.
1.Umthamo we-HPMC, nokusebenza kwayo kokugcinwa kwamanzi kuhambisana ngokuqondile nenani elingeziwe. Inani le-HPMC elisetshenziswa ezintweni zokwakha emakethe liyahlukahluka kuye ngekhwalithi. Ngokuvamile yengezwa njengokuhlanganisa, ukupulasitela, udaka olunqamula ukuqhekeka, njll. Inani elijwayelekile lokwengezwa ngu-2~2.5 KG /MT, inani elengezayo le-putty njll. liphakathi kuka-2~4.5 KG/MT, iglue yethayela phakathi kuka-3.5~4 KG/MT, futhi inani legrout likathayela lingu-0.3 ~1 KG/MT ngokwezindlela ezihlukene zokwakha, ububanzi begebe kanye nokucoleka kwe-slurry, udaka oluzilinganisa luphakathi kuka-0.2~0.6 KG/MT, kanye ne-ETICS iphakathi kuka-4~7 KG/MT. Ngaphakathi kwalolu hlu, uma i-HPMC yengezwa, ukusebenza kokugcinwa kwamanzi kungaba ngcono.
2.Umthelela wendawo yokwakha. Umswakama womoya, izinga lokushisa, umfutho womoya, isivinini somoya kanye nezinye izici zizothinta izinga lokuguquguquka kwamanzi odaka lukasimende kanye nemikhiqizo esekelwe ku-gypsum. Ezinkathini ezihlukene zonyaka nasezifundeni ezihlukene, izinga lokugcinwa kwamanzi lomkhiqizo ofanayo lizohluka, kodwa ngokuvamile, izinga lokushisa linethonya elikhulu esilinganisweni sokugcinwa kwamanzi, ngakho-ke kunombono emakethe: I-HPMC enejeli lokushisa eliphezulu iphezulu. -umkhiqizo wekhwalithi onezinga eliphezulu lokugcinwa kwamanzi.
3.Inqubo yokukhiqiza kanye ne-viscosity ye-cellulose ether -HPMC. Amaqembu e-methoxy kanye ne-hydroxypropoxy asatshalaliswa ngokulinganayo eduze kweketango lamangqamuzana e-cellulose, elingakhuphula ukuhlangana kwama-athomu omoya-mpilo ku-hydroxyl ne-ether bond namanzi. Ikhono le-hydrogen bonding lenza amanzi amahhala abe amanzi abophekile, ngaleyo ndlela alawule ngempumelelo ukuhwamuka kwamanzi futhi afinyelele ukugcinwa kwamanzi okuphezulu.
Lapho i-viscosity ye-HPMC ikhula, izinga lokugcinwa kwamanzi liyanda, i-viscosity ifinyelela ezingeni elithile, izinga lokugcinwa kwamanzi liyakhula. Ijwayele ukuba flat. Ukubuka konke okulula. Umsebenzi wokugcina amanzi we-HPMC uthintwa yizo zonke izici. Inketho ayikwazi ukususelwa kusikhombisi esisodwa.
