Qhov laj thawj vim li cas hydroxypropyl methylcellulose ntau dua thiab ntau dua diluted hauv cov hmoov putty

Qhov laj thawj vim li cashydroxypropyl methylcellulosepuas ntau dua thiab ntau dua diluted nyob rau hauv lub putty hmoov?

Thaum cov hmoov putty raug tsim thiab siv, ntau yam teeb meem yuav tshwm sim. Tom qab cov hmoov putty sib xyaw nrog dej thiab do nrog lub tshuab hluav taws xob, cov putty yuav nyias dua thaum nws raug do, thiab qhov tshwm sim ntawm kev sib cais dej yuav loj heev. Qhov ua rau muaj teeb meem no yog cov putty. Hydroxypropyl methylcellulose ntxiv rau hmoov.

1. Qhov viscosity ntawm hydroxypropyl methylcellulose tsis haum, qhov viscosity qis dhau, thiab qhov cuam tshuam ntawm kev ncua tsis txaus. Lub sijhawm no, qhov tshwm sim ntawm kev sib cais dej yuav loj heev, thiab qhov cuam tshuam ntawm kev ncua tsis tuaj yeem cuam tshuam.

2. Ntxiv cov tshuaj hydroxypropyl methylcellulose uas khaws dej rau hauv cov hmoov putty, uas muaj cov nyhuv khaws dej zoo heev. Thaum cov putty yaj rau hauv dej, nws kaw cov dej ntau heev. Lub sijhawm no, ntau cov dej tau sib xyaw ua ke rau hauv dej. Lub pob, thaum do, ntau cov dej raug cais tawm, yog li muaj teeb meem uas koj do ntau npaum li cas, nws yuav nyias dua; qhov no yog ib qho teeb meem tshwm sim, thiab ntau tus neeg tau ntsib teeb meem zoo li no. Qhov ntau ntawm cov cellulose ntxiv lossis cov dej noo ntxiv tuaj yeem txo kom haum.

3. Hydroxypropyl methylcellulosemuaj qee qhov kev sib raug zoo nrog nws tus kheej cov qauv. Nws muaj thixotropy, yog li tag nrho cov txheej muaj qee qhov thixotropy tom qab ntxiv cellulose, yog li thaum cov putty raug do sai, nws cov qauv tag nrho Dispersed, nws zoo li nyias dua, tab sis thaum nres, nws maj mam rov qab los.
