Iyiphi i-viscosity efaneleke kakhulu ye-hydroxypropyl methylcellulose

I-Hydroxypropyl methylcellulose ngokuvamile isetshenziswa ku-putty powder ene-viscosity ye-100,000, kuyilapho udaka lunesidingo esiphezulu se-viscosity, ngakho-ke kufanele sisetshenziswe nge-viscosity ye-150,000.Umsebenzi obaluleke kakhulu we-hydroxypropyl methylcellulose ukugcina amanzi, okulandelwa ukujiya.Ngakho-ke, ku-putty powder, inqobo nje uma ukugcinwa kwamanzi kufinyelelwa, i-viscosity iphansi.Ngokuvamile, uma i-viscosity inkulu, ukugcinwa kwamanzi kungcono, kodwa lapho i-viscosity idlula i-100,000, i-viscosity inomthelela omncane ekugcinweni kwamanzi.

Ngokusho kwe-viscosity, i-hydroxypropyl methylcellulose ivame ukuhlukaniswa ngezinhlobo ezilandelayo:

1. I-viscosity ephansi: I-cellulose ye-viscosity engu-400, ikakhulukazi esetshenziselwa udaka lokuzilinganisa.
Ine-viscosity ephansi kanye ne-fluidity enhle.Ngemuva kokwengeza, izolawula ukugcinwa kwamanzi ebusweni, ukuphuma kwegazi akubonakali, ukuncipha kuncane, ukuqhekeka kuncishisiwe, futhi kungamelana ne-sedimentation futhi kuthuthukise uketshezi nokudonsa.

2. I-viscosity ephakathi nendawo: 20,000-50,000 i-viscosity cellulose, ikakhulukazi esetshenziswa emikhiqizweni ye-gypsum kanye nama-caulking agents.
I-viscosity ephansi, ukugcinwa kwamanzi aphezulu, ukusebenza kahle, amanzi amancane angeziwe,

3. I-viscosity ephakathi: 75,000-100,000 i-viscosity cellulose, ikakhulukazi esetshenziselwa i-putty yangaphakathi nangaphandle yodonga.
I-viscosity emaphakathi, ukugcinwa kwamanzi okuhle, ukwakhiwa okuhle nokudonsa

4. I-viscosity ephezulu: 150,000-200,000, ikakhulukazi esetshenziselwa i-polystyrene particle insulation mortar rubber powder, vitrified microbead insulation mortar
Nge-viscosity ephezulu nokugcinwa kwamanzi aphezulu, udaka akulula ukulahla umlotha kanye ne-sag, okuthuthukisa ukwakhiwa.

Ngokuvamile, ukuphakama kwe-viscosity, ukugcinwa kwamanzi kangcono, ngakho amakhasimende amaningi azokhetha ukusebenzisa i-cellulose ye-viscosity ephakathi (75,000-100,000) esikhundleni se-cellulose ye-viscosity ephakathi nendawo (20,000-50,000) ukunciphisa inani elingeziwe, bese emva kwalokho. lawula izindleko
