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, ukuplasta, 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 nokucoleka okunodaka , 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 kakhulu, ukusebenza kokugcinwa kwamanzi kungaba ngcono.
2.Umthelela wendawo yokwakha.Umswakama womoya, izinga lokushisa, umfutho womoya, isivinini somoya nezinye izici zizothinta izinga lokuguquguquka kwamanzi odaka lukasimende kanye nemikhiqizo eyenziwe nge-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 enezinga lokushisa eliphezulu lejeli liphakeme kakhulu. -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 azuze ukugcinwa kwamanzi okuphezulu.
Lapho i-viscosity ye-HPMC ikhula, izinga lokugcinwa kwamanzi liyanda, i-viscosity ifinyelela izinga 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.
