Izinto ezifana nezinga lokushisa lomoya, izinga lokushisa kanye nomfutho womoya kuzothinta izinga lokushibilika komswakama odakeni lukasimende kanye nemikhiqizo esekelwe ku-gypsum.Ngakho-ke, ezinkathini ezihlukene zonyaka, umphumela wokugcina amanzi wenani elifanayo le-HPMC uhlukile.
Ekwakhiweni okukhethekile, umphumela wokugcina amanzi we-slurry ungalungiswa ngokwandisa noma ukwehlisa inani le-HPMC elingeziwe.Ukugcinwa kwamanzi kwe-hydroxypropyl methyl cellulose ether ngaphansi kwezimo zokushisa okuphezulu kuyinkomba ebalulekile yokuhlukanisa ikhwalithi ye-hydroxypropyl methyl cellulose ether.Imikhiqizo emihle kakhulu yochungechunge lwe-HPMC ingaxazulula ngempumelelo inkinga yokugcinwa kwamanzi emazingeni okushisa aphezulu.
Ezinkathini zokushisa eziphakeme, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa kongqimba oluncane ohlangothini olushisayo, i-HPMC yekhwalithi ephezulu iyadingeka ukuze kuthuthukiswe ukugcinwa kwamanzi odaka.Ikhwalithi ephezulu ye-HPMC inokufana okuhle kakhulu.Amaqembu ayo e-methoxy kanye ne-hydroxypropoxy asatshalaliswa ngokulinganayo eduze kweketango lamangqamuzana e-cellulose, elingathuthukisa ikhono lama-athomu oksijini ku-hydroxyl ne-ether bond ukuze ahlangane namanzi ukuze akhe izibopho ze-hydrogen, Ukuze amanzi amahhala abe amanzi abophekile, ngaleyo ndlela alawule ngokuphumelelayo. ukuhwamuka kwamanzi okubangelwa izinga lokushisa eliphezulu, nokuzuza ukugcinwa kwamanzi aphezulu.
Ikhwalithi ephezulu ye-cellulose HPMC ingahlakazwa ngendlela efanayo nangempumelelo odakeni lukasimende kanye nemikhiqizo esekelwe ku-gypsum, futhi isonge zonke izinhlayiya eziqinile, futhi yakhe ifilimu yokumanzisa.Amanzi asesisekelweni akhululwa kancane kancane isikhathi eside.Impahla ejiyile ithola ukusabela kwe-hydration ukuze kuqinisekiswe amandla okubopha kanye namandla acindezelayo wento.Ngakho-ke, ekwakhiweni kwehlobo lokushisa eliphezulu, ukuze kuzuzwe umphumela wokugcinwa kwamanzi, imikhiqizo yekhwalithi ephezulu ye-HPMC kufanele yengezwe ngamanani anele ngokuya ngefomula, ngaphandle kwalokho, ukufakwa kwamanzi okwanele, amandla ancishisiwe, ukuqhekeka, ukugoba nokuwa kubangelwa. ngokumiswa ngokweqile kuzokwenzeka.Kuphinde kwandise ubunzima bokwakha kubasebenzi.Njengoba izinga lokushisa lincipha, inani le-HPMC elingeziwe lingancishiswa kancane kancane, futhi umphumela ofanayo wokugcina amanzi ungafinyelelwa.
