Iyini i-viscosity ye-hydroxypropyl methylcellulose hpmc?

I-putty powder yezindonga zangaphakathi ngokuvamile ine-viscosity engu-100,000. Udaka lukasimende lunezidingo eziphakeme zokulungiswa, futhi i-viscosity ye-150,000 kulula ukuyisebenzisa. Ukwengeza, indima ebaluleke kakhulu ye-HPMC ukukhiya amanzi, okulandelwa ukujiya. Ku-putty powder, uma ukugcinwa kwamanzi kuhle futhi i-viscosity iphansi (7-80,000), ingaba ne-viscosity yemvelo ephakeme kanye nokugcinwa kwamanzi okungcono kakhulu. Lapho i-viscosity idlula i-100,000, i-viscosity inethonya elincane ekugcineni kwamanzi.

Uyini umphumela obalulekileI-HPMC ku-putty powder, nokuthi ngabe i-organic chemistry iyenzeka?

I-HPMC idlala imisebenzi emithathu yokujiya, ukugcinwa kwamanzi kanye nokwakha kumpuphu oyimpuphu.

Ukuqina: I-methylcellulose ingagxilwa ngezixazululo ezintantayo, ezinamanzi ukuze kugcinwe ukusebenza okufanayo nokungaguquguquki nokuvimbela ukulengiswa kokugeleza.

Ukugcina amanzi: Impushana yodonga lwangaphakathi yoma kancane, futhi i-calcium lime eyengeziwe ibonakala ekusetshenzisweni kwamanzi.

Ukwakhiwa kobunjiniyela: I-Methyl cellulose inomphumela wokugcoba, ongenza i-putty powder ibe nesakhiwo esihle kakhulu sobunjiniyela.

I-HPMC ayibandakanyeki kuzo zonke izinguquko zamakhemikhali kodwa kuphela ekwengezeni. I-putty powder, odongeni, iwushintsho lwamakhemikhali, ngoba kukhona ukuguqulwa kwamakhemikhali amasha, i-putty powder iphuma odongeni, igaye impushana, futhi iphinde isebenzise ngenxa yokuthi ikhemikhali entsha (i-calcium carbonate) ikhiqizwa.

Izingxenye eziyinhloko ze-calcium fly ash yilezi: i-Ca(oh)2, i-Cao kanye nenani elincane lezinhlanganisela ze-Caco3, i-Caoh2oCa(oh)2-Ca(oh)2caco3h2o lime ingaguqulwa ibe yi-calcium bicarbonate emanzini nasegesi, kuyilapho i-mpc amanzi kuphela ancibilikayo I-Calcium fly ash iwukubonakaliswa okunamandla, yona ngokwayo engabambi iqhaza kunoma yikuphi ukubonakaliswa.

Yini okufanele inakwe ekusetshenzisweni kwangempela kobudlelwane phakathi kwe-viscosity nezinga lokushisa le-HPMC?

I-viscosity ye-HPMC ilingana ngokuphambene nezinga lokushisa, ngamanye amazwi, i-viscosity iyanda ngokuncipha kwezinga lokushisa. I-viscosity yomkhiqizo, i-viscosity yomkhiqizo isho ukuthi isisombululo sawo esingu-2% sisezingeni lokushisa elingu-20 degrees Celsius, kanye nemiphumela yokuhlolwa.

Kuzicelo ezithile, ukunakwa kufanele kukhokhwe ezindaweni ezinomehluko omkhulu wokushisa phakathi kwehlobo nobusika, futhi kunconywa kakhulu ukusebenzisa i-viscosity ephansi ebusika. Uma kungenjalo, i-viscosity iphansi, i-viscosity ye-cellulose izokhula, futhi imihuzuko izoba nzima.

I-viscosity ephakathi: 75000-100000 ifanele i-putty powder
Isizathu: ukugcinwa kahle kwamanzi

I-viscosity ephezulu: i-150000-200000 ifaneleka i-polystyrene particle insulation mortar kanye ne-inorganic insulation mortar.
Izizathu: i-viscosity ephezulu, ukususwa okunzima kodaka lukasimende, ukulahlekelwa kwe-gloss, ukwakhiwa okuthuthukisiwe.
