I-Hydroxypropyl methyl cellulose(hpmc)ngokuvamile isetshenziswa ku-putty powder ene-viscosity ye-100000, kuyilapho udaka lunezidingo eziphakeme kakhulu ze-viscosity futhi kufanele zikhethwe nge-viscosity ye-150000 ukuze zisetshenziswe kangcono. Umsebenzi obaluleke kakhulu wei-hydroxypropyl methyl celluloseukugcina amanzi, okulandelwa ukujiya. Ngakho-ke, ku-putty powder, inqobo nje uma ukugcinwa kwamanzi kufinyelelwa futhi i-viscosity iphansi, kungenzeka futhi. Ngokuvamile, ukuphakama kwe-viscosity, kungcono ukugcina amanzi. Kodwa-ke, lapho i-viscosity idlula i-100000, umphumela we-viscosity ekugcinweni kwamanzi awubalulekile.

Jufu Building Material GradeI-Hydroxypropyl Methyl CelluloseIhlukaniswa nge-Viscosity, ngokuvamile ihlukaniswe ngezinhlobo ezilandelayo:

1. I-viscosity ephansi: I-cellulose ye-viscosity engu-400, ikakhulukazi esetshenziselwa udaka lokuzilinganisa. I-viscosity ephansi, ukugeleza okuhle, futhi ngemva kokwengeza, izolawula ukugcinwa kwamanzi angaphezulu. Ukopha akubonakali, ukushwabana kuncane, nokuqhekeka kuyancipha. Ingakwazi futhi ukumelana ne-sedimentation, ithuthukise ukugeleza nokudonsa.
2. I-viscosity ephakathi kuya ephansi: 20000 kuya ku-50000 i-viscosity cellulose, ikakhulukazi esetshenziselwa imikhiqizo ye-gypsum kanye nama-filler ahlangene. I-viscosity ephansi, ukugcinwa kahle kwamanzi, ukusebenza kahle, nokwengezwa kwamanzi aphansi,
3. I-viscosity ephakathi: 75000-100000 i-viscosity cellulose, ikakhulukazi esetshenziselwa i-putty yangaphakathi nangaphandle yodonga. I-viscosity emaphakathi, ukugcinwa kahle kwamanzi, kanye ne-drape enhle yokwakha.
4. I-viscosity ephezulu: 150000 kuya ku-200000 yuan, ikakhulukazi esetshenziselwa i-polystyrene inhlayiyana yokufaka i-powder material, i-vitrified micro bead insulation mortar ene-viscosity ephezulu nokugcinwa kwamanzi. Udaka akulula ukuwa nokulenga, ukuthuthukisa ukwakhiwa.
Ngokuvamile, ukuphakama kwe-viscosity, kungcono ukugcina amanzi. Ngakho-ke, amakhasimende amaningi akhetha ukusebenzisa i-cellulose ye-viscosity ephakathi (75000-100000) esikhundleni se-cellulose ephansi ye-viscosity ephakathi (20000-50000) ukuze kuncishiswe inani lezindleko zokwengeza nokulawula.
I-viscosity yeI-HPMCilingana ngokuphambene nezinga lokushisa, ngamanye amazwi, i-viscosity iyanda ngokuncipha kwezinga lokushisa. I-viscosity yomkhiqizo isho ukuthi isisombululo sawo esingu-2% sisezingeni lokushisa elingu-20 degrees Celsius, futhi imiphumela yokuhlolwa inembile.
Kuzicelo ezithile, ukunakwa kufanele kukhokhwe ezindaweni ezinomehluko omkhulu wokushisa phakathi kwehlobo nobusika, futhi kunconywa kakhulu ukusebenzisa i-viscosity ephansi ebusika. Uma kungenjalo, uma i-viscosity iphansi, i-viscosity ye-cellulose izokhula futhi imihuzuko izoba nzima.
