Yiyiphi eyona viscosity ifanelekileyo ye-hydroxypropyl methylcellulose

I-Hydroxypropyl methylcellulose ngokuqhelekileyo isetyenziselwa i-putty powder kunye ne-viscosity ye-100,000, ngelixa udaka lunemfuno ephezulu ye-viscosity, ngoko kufuneka isetyenziswe nge-viscosity ye-150,000.Owona msebenzi ubalulekileyo we-hydroxypropyl methylcellulose kukugcina amanzi, kulandelwa kukuqina.Ngoko ke, kwi-putty powder, ngokude nje ukugcinwa kwamanzi kufezekiswa, i-viscosity iphantsi.Ngokuqhelekileyo, i-viscosity enkulu, ngcono ukugcinwa kwamanzi, kodwa xa i-viscosity idlula i-100,000, i-viscosity inempembelelo encinci ekugcineni amanzi.

Ngokwe-viscosity, i-hydroxypropyl methylcellulose yohlulwe ngokubanzi kwezi ntlobo zilandelayo:

1. I-viscosity ephantsi: i-cellulose ye-viscosity ye-400, eyona nto isetyenziselwa udaka lokuzimela.
Ine-viscosity ephantsi kunye ne-fluidity elungileyo.Emva kokongeza, iya kulawula ukugcinwa kwamanzi kumphezulu, ukopha akubonakali, ukucutha kuncinci, ukuqhekeka kuncitshisiwe, kwaye kunokuxhathisa ukuchithwa kunye nokwandisa umbane kunye nokumpompa.

2. I-viscosity ephakathi kunye nephantsi: i-20,000-50,000 i-viscosity cellulose, esetyenziswa kakhulu kwiimveliso ze-gypsum kunye ne-caulking agents.
I-viscosity ephantsi, ukugcinwa kwamanzi aphezulu, ukusebenza kakuhle, ukongezwa kwamanzi amancinci,

3. I-viscosity ephakathi: i-75,000-100,000 i-viscosity cellulose, isetyenziselwa ngokukodwa kwi-putty yodonga lwangaphakathi nangaphandle.
I-viscosity ephakathi, ukugcinwa kakuhle kwamanzi, ukwakhiwa kakuhle kunye nokudonsa

4. I-viscosity ephezulu: 150,000-200,000, ikakhulu esetyenziselwa i-polystyrene i-particle insulation i-rubber powder powder, i-vitrified microbead insulation mortar.
Nge-viscosity ephezulu kunye nokugcinwa kwamanzi aphezulu, udaka alulula ukulahla umlotha kunye ne-sag, okuphucula ukwakhiwa.

Ngokuqhelekileyo, okukhona i-viscosity ephezulu, ngcono ukugcinwa kwamanzi, abathengi abaninzi baya kukhetha ukusebenzisa i-cellulose ye-viscosity ephakathi (75,000-100,000) endaweni ye-cellulose ye-viscosity ephakathi (20,000-50,000) ukunciphisa inani elongezelelweyo, kwaye emva koko. ukulawula iindleko
