Ukusetshenziswa kwe-viscosities ehlukahlukene ye-cellulose emikhiqizweni

I-industrial grade hydroxypropyl methylcellulose esetshenziselwa udaka (lapha isho i-cellulose emsulwa, ngaphandle kwemikhiqizo eguquliwe) ihlukaniswa nge-viscosity, futhi amabanga alandelayo asetshenziswa ngokujwayelekile (iyunithi i-viscosity):

I-viscosity ephansi: 400

Isetshenziselwa ikakhulukazi udaka lokuzilinganisa;i-viscosity iphansi, nakuba ukugcinwa kwamanzi kumpofu, kodwa impahla yokulinganisa inhle, futhi ukuminyana kodaka kuphezulu.

I-viscosity ephakathi nendawo: 20000-40000

Ikakhulu isetshenziselwa izinto zokunamathisela zamathayili, ama-caulking agents, ama-anti-cracking mortars, ama-thermal insulation bonding mortars, njll.;ukwakhiwa okuhle, amanzi amancane, ukuminyana kodaka oluphezulu.

I-viscosity ephakathi: 75000-100000

Ikakhulu isetshenziselwa i-putty;ukugcinwa kwamanzi okuhle.

I-viscosity ephezulu: 150000-200000

Isetshenziselwa ikakhulukazi i-polystyrene particle thermal insulation mortar rubber powder kanye ne-vitrified microbead thermal insulation mortar;i-viscosity iphezulu, udaka akulula ukuwa, futhi ukwakhiwa kuyathuthukiswa.

Ekusetshenzisweni okusebenzayo, kufanele kuqashelwe ukuthi ezindaweni ezinomehluko omkhulu wokushisa phakathi kwehlobo nobusika, kunconywa ukusebenzisa i-viscosity ephansi kakhulu ebusika, evumelana kakhulu nokwakhiwa.Uma kungenjalo, lapho izinga lokushisa liphansi, i-viscosity ye-cellulose izokhula, futhi ukuzwa kwesandla kuyoba nzima lapho kukhuhla.

Ngokuvamile, ukuphakama kwe-viscosity, kungcono ukugcina amanzi.Uma kucatshangelwa izindleko, amafekthri amaningi e-powder mortar eyomile ashintsha i-cellulose ye-viscosity ephakathi nendawo (20000-40000) nge-medium-viscosity cellulose (75000-100000) ukunciphisa inani lokuhlanganisa.Imikhiqizo yodaka kufanele ikhethwe kubakhiqizi abajwayelekile futhi ikhonjwe.

Ubudlelwano phakathi kwe-viscosity nezinga lokushisa le-HPMC:

I-viscosity ye-HPMC ihambisana ngokuphambene nezinga lokushisa, okungukuthi, i-viscosity iyanda njengoba izinga lokushisa liyancipha.I-viscosity yomkhiqizo esivame ukubhekisela kuwo ibhekisela kumphumela wokuhlolwa wesisombululo sawo samanzi esingu-2% ezingeni lokushisa elingu-20 degrees Celsius.
