Ukugcinwa kwamanzi okuvela ku-hydroxypropyllylylylylylylylylylyllose kungenye yezindawo ezibalulekile ze-hydroxypropylylylylylylylyllose. Izici ezinjengokushisa komoya, izinga lokushisa nejubane lokucindezela komoya lizothinta izinga lokuzithambisa kwamanzi emikhiqizweni yodaka kasimende nemikhiqizo esekwe e-gypsum. Therefore, in different seasons, there are some differences in the water retention effect of products with the same amount of Hydroxypropyl Methyl Cellulose added.
Ngokuvamile, ukukhuphuka kwe-viscoxyprotity methyl cellulose, okungcono umphumela wokugcinwa kwamanzi kuzoba, kepha umphumela wokutholwa kwamanzi uzoncishiswa lapho i-viscoty idlula i-100,000 MPA.S. For Hydroxypropyl Methyl Cellulose with a viscosity of more than 100,000, it is necessary to increase the amount of Hydroxypropyl Methyl Cellulose to significantly increase the water retention rate.
Ekwakhiweni okuthile, umphumela wokugcinwa kwamanzi angashintshwa ngokwanda noma ukwehlisa inani le-hydroxypropylylylylylylylylylylylylylylylylylylylylylylylylylylyllop methyl. Imikhiqizo yochungechunge lwe-Hydroxypropllylylyllyllylylyllyprosel. Ezimweni zokushisa eziphakeme, ikakhulukazi ezindaweni ezishisayo nezisomile kanye nokwakhiwa okunezinxenye zelanga ohlangothini olunelanga, i-hydroxyproppropylylylylylylyrullellose iyadingeka ukuthuthukisa ukugcinwa kwamanzi kwe-slurry.
I-hydroxypropproppropylk methyl cellulose inokufana okuhle kakhulu. Amaqembu ayo we-methoxy ne-hydroxypropopoxy asatshalaliswa ngokulinganayo kanye ne-cellulose molecular chain. Kungathuthukisa ama-athomu oksijini ku-hydroxyl kanye ne-ether. Amandla wenhlangano yamanzi ukwakha amabhondi e-hydrogen aphenduka amanzi akhululekile emanzini aboshwe, ngaleyo ndlela alawule ukuhwamuka kwamanzi okubangelwa isimo sezulu esiphakeme kanye nokuthola ukugcinwa kwamanzi okuphezulu.
I-hydroxypropproppropyll methyl cellulose ingahlakaza ngokulinganayo futhi ngempumelelo ihlakazeke ngemikhiqizo esuselwa kumasipala we-gypsum, ukugoqa zonke izinhlayiya eziqinile, futhi yakha ifilimu eliqinile, futhi umswakama ophansi uzodedelwa kancane kancane isikhathi eside. Ukusabela kwe-hydration kwenzeka ngezinto zokugibela ama-inorganic, ngaleyo ndlela kuqinisekiswe amandla ebhondi namandla acindezelayo wezinto ezibonakalayo. Ngakho-ke, ekwakhiweni kwamazinga okushisa aphezulu, ukuze kufinyelelwe umphumela wokugcina amanzi, kuyadingeka ukufaka imikhiqizo esezingeni eliphakeme ye-hydroxyproppropyll methyl celtule Izinkinga zekhwalithi ezinjengokukhohlisa, ezinamafutha nokuwa nazo zandisa ubunzima bokwakhiwa kwabasebenzi. Njengoba amazinga okushisa ehla, inani le-hydroxypropyllllylylyllyllopylllllllll ltulose elingeziwe lingancishiswa kancane kancane, futhi umphumela wokugcina amanzi afanayo angatholakala.
