Isidingo sokwengeza i-hydroxypropyllym methylcellulose (HPMC) kwimikhiqizo yodaka kanye ne-gypsum esekwe ku-Gypsum!

Ku-celtersar udaka olususelwa e-gypsum, i-hydroxypropylm methylcellulose ikakhulukazi idlala indima yokugcinwa kwamanzi kanye nokuqina, okungathuthukisa kahle ukubumbana nokuphikiswa kwe-slurry. Izici ezinjengokushisa komoya, izinga lokushisa kanye nokucindezela komoya kuzothinta izinga lokuhwamuka kwamanzi ku-Cement Saturn Datar and Gypsum-based Products. Ngakho-ke, ngezinkathi ezihlukene, kukhona umehluko othile emphumeleleni wokugcina amanzi wemikhiqizo ngenani elifanayo le-hydroxypropylylylylylylyllose angeziwe. Ekwakhiweni okuthize, umphumela wokugcinwa kwamanzi we-slurry ungashintshwa ngokwanda noma ukwehlisa inani le-HPMC elingeziwe. Ukugcinwa kwamanzi kwe-methyl cellulose ether ekushiseni okuphezulu kuyinkomba ebalulekile yokuhlukanisa ikhwalithi ye-methyl cellulose ether.

Imikhiqizo yochungechunge lwe-hydylcelprose methylcellose methylcellose ingaxazulula inkinga yokugcinwa kwamanzi ngokushisa okuphezulu. Esikhathini sokushisa esiphakeme, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa kwesendlalelo ohlangothini olunelanga, i-HPMC esezingeni eliphakeme iyadingeka ukuthuthukisa ukugcinwa kwamanzi kwe-slurry.

I-HPMC esezingeni eliphakeme, ngokufana okuhle, amaqembu ayo we-methopp kanye ne-hydroxypropoxy asatshalaliswa ngokulandelana kwama-athomu ama-athomu asolaka ama-athomu asomathe ama-hydrogel, ukuze akwazi ukuhambisa amanzi okushisa okubangelwa isimo sezulu esiphakeme futhi athole ukugcinwa kwamanzi okuphezulu. Amanzi ayadingeka kuma-hydration ukuze asethe izinto zokwenza kahle ezifana nesimende ne-gypsum. Inani elifanele le-HPMC lingagcina amanzi odongeni olude ngokwanele ukuvumela ukusetha kanye nenqubo eqinile ukuqhubeka.
Inani le-HPMC elidingekayo ukuthola amandla anele okugcina amanzi ancike ku:
1. Ukutholwa kwesendlalelo sesisekelo

2. Ukwakheka kodaka

3. Ubukhulu bodaka

4. Isidingo samanzi sodaka

I-5. Isikhathi sokubeka impahla ekhohlisayo

I-hydroxyproppropyll esezingeni eliphakeme ingahlakazwa ngokufana futhi ihlakazeke ngempumelelo emikhiqizweni yodaka kasimende kanye ne-gypsum, futhi isonde zonke izinhlayiya eziqinile, futhi yakha ifilimu eliqinile, futhi umswakama osesisekelweni udedelwa kancane kancane. , futhi ukusabela kwe-hydration kwenzeka ngezinto zokufakazelwa kwamakhemihli amancane, ngaleyo ndlela kuqinisekiswe amandla okuqinisa namandla okucindezela kwezinto ezibonakalayo.
isithombe

Ngakho-ke, ekwakhiweni kwehlobo lokushisa okuphezulu, ukuze kufinyelelwe umphumela wokugcinwa kwamanzi, kuyadingeka ukwengeza imikhiqizo ye-HPMC ephezulu ngamanani anele ngokuya ngefomula, ukuncishiswa kwamandla, ukuqhekeka, ukuqhekeka, ukuqhekeka, ukuwa nokuwa futhi kuwa okubangelwa ukomisa okusheshayo. Iphinde yandise ubunzima bokwakhiwa kwabasebenzi. Njengoba izinga lokushisa lincipha, inani lokungezwa le-HPMC lingancishiswa kancane kancane, futhi imiphumela efanayo yokugcina amanzi ingatholakala.
