Hydroxypropyl methylcellulose tuaj yeem siv rau hauv putty nrog viscosity ntawm 100,000, thaum lub viscosity ntawm cement mortar yuav tsum siab, uas yuav tsum yog 150,000.Hydroxypropyl Methyl Cellulose ua lub luag haujlwm tseem ceeb hauv kev tswj cov dej noo thiab thickening.Yog li ntawd, nyob rau hauv putty, tsuav yog cov dej tuav tau tiav, lub viscosity yuav txo.Feem ntau hais lus, qhov viscosity siab dua, qhov dej tuav tau zoo dua, tab sis thaum lub viscosity siab tshaj 100,000, viscosity tsis tshua muaj txiaj ntsig rau cov dej tuav.
Cov khoom siv hauv tsev zoo nkauj qib hydroxypropyl methylcellulose feem ntau tuaj yeem muab faib ua pawg hauv qab no raws li viscosity:
1. Tsawg viscosity: 400-viscosity cellulose tsuas yog siv rau hauv tus kheej-leveling mortar.
Tsis tshua muaj viscosity, zoo flowability, tom qab ntxiv, cov dej tuav kev ua tau zoo ntawm cov txheej txheej saum npoo yog tswj, cov ntshav los ntshav tsis pom tseeb, qhov shrinkage me me, tawg, tiv thaiv sedimentation, thiab txhim kho flowability thiab pumpability.
2. Tsawg thiab nruab nrab viscosity: feem ntau yog siv nyob rau hauv 20,000-500,000 viscosity cellulose rau plaster ntawm paris cov khoom thiab cov khoom sib koom ua ke.Tsawg viscosity, siab dej tuav, ua haujlwm zoo, dej ntws tsawg.
3. Lub teeb rau nruab nrab viscosity: Feem ntau yog siv rau sab hauv thiab sab nrauv phab ntsa putty, lub viscosity nyob nruab nrab ntawm 75000-10000.Nruab nrab viscosity, zoo tuav dej, zoo drapability nyob rau hauv engineering tsim.
4. High viscosity: Nws yog tsuas yog siv nyob rau hauv polystyrene particle rwb thaiv tsev mortar hmoov thiab inorganic rwb thaiv tsev mortar rau ntau tshaj 150,000-200,000 yuan.
Cement mortar muaj viscosity siab, dej tuav, thiab tsis yooj yim rau poob thiab dent, yog li txhim kho kev tsim kho.
Feem ntau hais lus, qhov siab dua qhov viscosity ntawm hydroxypropyl methylcellulose, qhov dej tuav tau zoo dua.Yog li ntawd, txhawm rau txo qhov nce thiab txo tus nqi, ntau tus neeg siv khoom yuav xaiv siv cov viscosity cellulose tsawg (75000-10000 es tsis txhob muaj cov viscosity cellulose tsawg.
Ntau hom cellulose: ntau hom cellulose tuaj yeem siv rau hauv kev tsim kho engineering, kev lag luam khoom noj thiab tshuaj, kev lag luam tshuaj niaj hnub, kev lag luam petrochemical thiab lwm yam lag luam.
