Umphumela ongcono we-hydroxypropyl methylcellulose ekugcinweni kwamanzi odaka lwesakhiwo

1. Isidingo sokugcinwa kwamanzi kwe-hydroxypropyl methylcellulose

Ukugcinwa kwamanzi odaka kubhekisela emandleni odaka ukugcina amanzi. Udaka olungagcini kahle amanzi lujwayele ukopha nokuhlukaniswa ngesikhathi sokuthutha nokugcinwa, okungukuthi, amanzi antanta phezulu, nesihlabathi nosimende usinki ngezansi. Kufanele ihlanganiswe kabusha ngaphambi kokusetshenziswa. Zonke izinhlobo zezisekelo ezidinga udaka ukuze zakhiwe zinokumuncwa okuthile kwamanzi. Uma ukugcinwa kwamanzi kodaka kungalungile, udaka oluxubekile luzomuncwa ngokushesha nje lapho udaka oseluvele luhlangene luhlangana nebhulokhi noma isisekelo ngesikhathi sokusetshenziswa kodaka. Ngesikhathi esifanayo, indawo engaphandle yodaka ihwamulisa amanzi emkhathini, okuholela ekubeni nomswakama onganele odakeni ngenxa yokuphelelwa amanzi emzimbeni, okuthinta ukugeleza okwengeziwe kukasimende, futhi ngesikhathi esifanayo kuthinta ukuthuthukiswa okuvamile kwamandla odaka. , okubangela amandla, ikakhulukazi ukuxhumana phakathi kodaka oluqinile kanye nesendlalelo sesisekelo. iba ngaphansi, okwenza udaka luqhekeke futhi liwe. Ngodaka olunokugcinwa kwamanzi okuhle, i-cement hydration yanele ngokwanele, amandla angathuthukiswa ngokujwayelekile, futhi angahlanganiswa kangcono nesendlalelo sesisekelo.

2. Izindlela zendabuko zokugcina amanzi

Isixazululo sendabuko ukunisela isisekelo, kodwa akunakwenzeka ukuqinisekisa ukuthi isisekelo siswakanyiswe ngokulinganayo. Umgomo ofanelekile we-hydration wodaka lukasimende esisekelweni uwukuthi: umkhiqizo we-cement hydration ungena esisekelweni kanye nenqubo yesisekelo esimunca amanzi, sakha "ukuxhumana okubalulekile" okuphumelelayo nesisekelo, ukuze kuzuzwe amandla esibopho adingekayo. Ukunisela ngokuqondile phezu kwesisekelo kuzodala ukuhlakazeka okukhulu ekumunceni kwamanzi kwesisekelo ngenxa yokuhluka kwezinga lokushisa, isikhathi sokunisela, nokufana kokunisela. Isisekelo sinokumuncwa okuncane kwamanzi futhi sizoqhubeka nokumunca amanzi osimende. Ngaphambi kokuqhubeka kwe-cement hydration, amanzi adonswa, okuthinta ukungena kwe-cement hydration kanye nemikhiqizo ye-hydration ku-matrix; isisekelo sinokumuncwa okukhulu kwamanzi, futhi amanzi odaka agelezela esisekelweni. Ijubane eliphakathi lokufuduka lihamba kancane, futhi ngisho nongqimba olunothile ngamanzi luyakhiwa phakathi kodaka kanye ne-matrix, okuphinde kuthinte amandla esibopho. Ngakho-ke, ukusebenzisa indlela evamile yokunisela isisekelo ngeke nje kuhluleke ukuxazulula ngokuphumelelayo inkinga yokumuncwa kwamanzi amaningi kwesisekelo sodonga, kodwa kuzothinta amandla okubopha phakathi kodaka nesisekelo, okuholela ekubhobozeni nasekuqhekekeni.

3. Indima ye-hydroxypropyl methylcellulose ekugcineni amanzi

Ukusebenza kokugcinwa kwamanzi kwe-hydroxypropyl methylcellulose kunezinzuzo eziningi:

(1). Ukusebenza okuhle kakhulu kokugcinwa kwamanzi kwenza udaka luvuleke isikhathi eside, futhi lunobuhle bokwakhiwa kwendawo enkulu, impilo ende yesevisi emgqonyeni, kanye nokuxuba inqwaba kanye nokusetshenziswa kwenqwaba.

(2). Ukusebenza kahle kokugcinwa kwamanzi kwenza usimende odakeni ube namanzi ngokugcwele, okwenza ngcono ngempumelelo ukusebenza kwesibopho sodaka.

(3). Udaka lusebenza kahle kakhulu ekugcineni amanzi, okwenza udaka lungabi lula ukuhlukaniswa nokopha, futhi luthuthukise ukusebenza kanye nokwakheka kodaka.
