Dab tsi yog qhov tsim nyog tshaj plaws viscosity ntawm hydroxypropyl methylulose

HydroxyPropyyl methylulose feem ntau yog siv nyob rau hauv putty hmoov nrog viscosity ntawm 100 qhov kev xav tau siab muaj, yog li nws yuav tsum tau siv nrog viscosity ntawm 150,000. Cov haujlwm tseem ceeb tshaj plaws ntawm hydroxypropyl methylcellulose yog dej cia, ua raws li thickening. Yog li ntawd, nyob rau hauv cov hmoov putty, tsuav li lub taub dej tuav cia yog tiav, lub viscosity yog qis dua. Feem ntau hais lus, ntau hom neeg viscosity, tab sis thaum lub viscosity tshaj 100,000, lub viscosity muaj cov nyhuv me me rau ntawm cov dej khaws cia.

Raws li cov viscosity, hydroxypropy kasthylcellulose feem ntau muab faib ua cov hauv qab no:

1. Muaj viscosity tsawg: 400 viscosity cellulose, feem ntau yog siv rau kev sib nphoo tus kheej.
Nws muaj viscosity tsawg thiab zoo fluidity. Tom qab ntxiv, nws yuav tswj cov dej khaws cia ntawm qhov chaw, qhov kev los ntshav yog tsis pom tseeb, thiab nws tuaj yeem tawm tsam cov nqaij sedimentitation thiab txhim kho fluentity thiab purchity.

2. Nruab nrab thiab qis viscosity: 20,000-50,000 viscosity cellulose, feem ntau yog siv hauv gypsum khoom thiab caulking cov neeg sawv cev.
Tsawg viscosity, cov dej siab khaws cia, ua haujlwm tau zoo, tsawg dua dej ntxiv,

3. Nruab nrab viscosity: 75,000-100,000 viscosity cellulose, feem ntau yog siv rau phab ntsa sab hauv thiab sab nrauv putty.
Cov viscirecosity me me, cov dej ua kom zoo, tsim kho kom zoo thiab drapility

4. Cov viscosity siab: 150,000, tsuas yog siv rau polystyrene particoll cap roj hmab hmoov
Nrog cov dej viscosity siab thiab cov dej siab khaws cia, lub cug tsis yooj yim kom poob tshauv thiab sag, uas txhim kho kev tsim kho.

Feem ntau hais lus, ntau dua cov viscosity, ntau dua cov neeg siv khoom yuav xaiv viscosity cellivos (20,000-50,000 tus nqi ntxiv, thiab tom qab ntawd tswj tus nqi
