Kusimende nodaka olusekelwe ku-gypsum, i-HPMC idlala kakhulu indima yokugcina amanzi kanye nokujiya.Ingathuthukisa ngempumelelo amandla okubopha kanye ne-anti-pituitarism ye-slurry.
Izinga lokushisa lomoya, izinga lokushisa lomoya kanye nesivinini somfutho womoya kuthinta izinga lokuguquguquka kwamanzi odaka lukasimende kanye nemikhiqizo esekelwe ku-gypsum.
Ezinkathini ezihlukene zonyaka, kunomehluko othile kumphumela wokugcina amanzi we-HPMC.Ekwakhiweni okukhethekile, umphumela wokugcina amanzi we-slurry ungalungiswa ngokwandisa noma ukwehlisa inani le-HPMC elingeziwe.Ukugcinwa kwamanzi kwe-methyl cellulose ether ngaphansi kwezimo zokushisa okuphezulu kuyinkomba ebalulekile yokuhlukanisa ikhwalithi ye-methyl cellulose ether.Imikhiqizo emihle kakhulu yochungechunge lwe-HPMC ingaxazulula ngokuphumelelayo inkinga yokugcinwa kwamanzi ngaphansi kwezinga lokushisa eliphezulu.
Esikhathini sokushisa okuphezulu, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa kongqimba oluncane ohlangothini olunelanga.Ikhwalithi ephezulu ye-HPMC iyadingeka ukuze kuthuthukiswe ukugcinwa kwamanzi odaka.Ingathuthukisa ikhono le-athomu ye-oxygen eqenjini le-hydroxyl ukwakha ibhondi ye-hydrogen nebhondi ye-ether.Yenza amanzi amahhala abe amanzi abophekile, ukuze ulawule ngempumelelo ukuhwamuka kwamanzi okubangelwa izinga lokushisa eliphezulu.Izinga eliphezulu lokugcina amanzi.
Ikhwalithi ephezulu ye-cellulose HPMC ingahlakazwa ngendlela efanayo nangempumelelo odakeni lukasimende kanye nemikhiqizo esekwe ku-gypsum.Bese ugoqa zonke izinhlayiya eziqinile ukuze wenze ifilimu yokumanzisa.Umswakama oseqenjini lesisekelo ukhululwa kancane kancane isikhathi eside, futhi i-inorganic gelling material ibhekana nokusabela kwe-hydration.Ngaleyo ndlela kuqinisekisa amandla ebhondi namandla acindezelayo wento.Ngakho-ke, kufanele yakhiwe ehlobo lokushisa eliphezulu ukuze kuzuzwe umphumela wokugcina amanzi.Qiniseka ukuthi ungeza imikhiqizo yekhwalithi ephezulu ye-HPMC ngokuya ngefomula, ngaphandle kwalokho kuzoba nezinkinga zekhwalithi njengokunganele kwe-hydration.Kodwa futhi kwandisa ubunzima bokwakha kwabasebenzi.Njengoba izinga lokushisa lehla, inani le-HPMC lingancishiswa kancane kancane, futhi umphumela wokugcina amanzi nawo ungafinyelelwa.
