I-Hydroxypropyl Methylcellulose (HPMC) yi-ether ye-cellulose engekho eyenziwe kusuka ku-Natural Polymer Matelioser cellulose ngochungechunge lwezinqubo zamakhemikhali. I-Hydroxypropylmethylcellulose (HPMC) iyimpuphu ye-White engenamzimba engenamqondo, engenambitha, engeyona into enobuthi engachithwa emanzini abandayo ukwakha isixazululo esibonakalayo esibonakalayo. Inezakhiwo zokuqina, ukubopha, ukusabalalisa, ukusabalalisa, ukuhlalisa ifilimu, ukumisa amafilimu, ama-adsorbing, ukugcinwa phansi, ukulondolozwa komhlaba, ukugcina umswakama nokuvikela umswakama nokuvikela i-colloid. Ku-swatar, umsebenzi obalulekile we-hydroxypropyllllllylylylyll methylcellulose ukugcinwa kwamanzi, okuyikhono lodaka lokugcina amanzi.
1. Ukubaluleka kokugcinwa kwamanzi ngodaka
Udaka ngokugcinwa kwamanzi ampofu kulula ukukopela futhi uhlukanise ngesikhathi sokuhamba nokugcinwa, okungukuthi, amanzi entanta ngaphezulu, isihlabathi kanye nesimende kucwila ngezansi, futhi kufanele avuse kabusha ngaphambi kokusetshenziswa. Udaka ngokugcinwa kwamanzi okumpofu, enqubweni yokufakelwa, inqobo nje uma udaka olulodwa oluhlanganisiwe luhlangana nebhulokhi noma isisekelo, udaka oluxubile luzodonswa ngamanzi, futhi ngasikhathi sinye, indawo yangaphandle Udaka luzophuma amanzi emkhathini, okuholela ekulahlekelweni kwamanzi odaka. Amanzi anganele azothinta enye i-hydration ka usimende futhi athinte ukuthuthukiswa okujwayelekile kwamandla kadaka, okuholela emandleni aphansi, ikakhulukazi amandla aphakathi kolimi olukhuni kanye nongqimba lwesisekelo, okuholela ekuqhekekeni futhi kuphumela ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele ekuqhekekeni futhi kuholele kudaka.
2. Indlela yendabuko yokuthuthukisa ukugcinwa kwamanzi kodaka
Isixazululo sendabuko ukunisela isisekelo, kepha akunakwenzeka ukuqinisekisa ukuthi isisekelo siyanyiswa ngokulinganayo. Umgomo ofanele we-hydration ka usimende wodaka esisekelweni yile: Umkhiqizo we-Cement Hydration ungene esisekelweni kanye nenqubo yesisekelo samanzi, ukwakha amandla asebenzayo e-Base. Ukunisela ngqo ebusweni besisekelo kuzodala ukuhlakazeka okukhulu ekutholeni kwamanzi kwesisekelo ngenxa yokungafani kokushisa, isikhathi sokunisela kanye nokunisela. Isisekelo sinokutholwa kwamanzi okuncane futhi sizoqhubeka nokudonsa amanzi odongeni. Ngaphambi kokuba i-cydy ye-cydration iyaqhubeka, amanzi amunwa, okuthinta ukungena kwe-yment hydration nemikhiqizo ye-hydration kwi-matrix; Isisekelo sinokuthathwa kwamanzi okukhulu, namanzi asosimende ageleza ezansi. Ijubane lokufuduka eliphakathi lihamba kancane, futhi noma ungqimba olunothile lwamanzi kwakheka phakathi kodaka kanye ne-matrix, okubuye kuthinta amandla e-bond. Ngakho-ke, ukusebenzisa indlela ejwayelekile yokunisela izisekelo ngeke kuhluleke kuphela ukuxazulula inkinga yokufakwa kwamanzi okuphezulu kwesisekelo sodonga, kepha kuzothinta amandla okubopha phakathi kodaka kanye nesisekelo, okuholela ekuhlolweni nasekuhlanganeni.
3. Ukugcinwa okusebenzayo kwamanzi

(3) Udaka unokusebenza okuhle kakhulu kokugcinwa kwamanzi, okwenza ukuthi udaka aluthambekele kancane ekuhlukaniseleni nokopha, okuthuthukisa ukusebenza nokwakhiwa kodaka.
