Hydroxypropyl methylcellulose feem ntau yog siv rau hauv cov hmoov putty nrog viscosity ntawm 100,000, thaum mortar muaj qhov yuav tsum tau muaj viscosity siab, yog li nws yuav tsum tau siv nrog viscosity ntawm 150,000.Qhov tseem ceeb tshaj plaws ua haujlwm ntawm hydroxypropyl methylcellulose yog dej tuav, ua raws li thickening.Yog li ntawd, nyob rau hauv cov hmoov putty, tsuav yog cov dej tuav tau tiav, lub viscosity yog qis dua.Feem ntau hais lus, qhov viscosity ntau dua, qhov dej tuav tau zoo dua, tab sis thaum lub viscosity siab tshaj 100,000, qhov viscosity tsis tshua muaj txiaj ntsig rau cov dej tuav.
Raws li viscosity, hydroxypropyl methylcellulose feem ntau muab faib ua cov hauv qab no:
1. Tsawg viscosity: 400 viscosity cellulose, feem ntau yog siv rau tus kheej-leveling mortar.
Nws muaj viscosity tsawg thiab zoo fluidity.Tom qab ntxiv, nws yuav tswj cov dej tuav ntawm qhov chaw, los ntshav tsis pom tseeb, qhov shrinkage me me, qhov tawg yog txo, thiab nws kuj tuaj yeem tiv taus sedimentation thiab txhim khu fluidity thiab pumpability.
2. Nruab nrab thiab qis viscosity: 20,000-50,000 viscosity cellulose, feem ntau yog siv hauv cov khoom gypsum thiab cov tshuaj tua kab mob.
Tsawg viscosity, siab tuav dej, ua haujlwm tau zoo, tsis muaj dej ntxiv,
3. Nruab nrab viscosity: 75,000-100,000 viscosity cellulose, feem ntau yog siv rau sab hauv thiab sab nrauv phab ntsa putty.
Nruab nrab viscosity, zoo tuav dej, zoo tsim thiab drapability
4. High viscosity: 150,000-200,000, feem ntau yog siv rau polystyrene particle rwb thaiv tsev mortar roj hmab hmoov, vitrified microbead rwb thaiv tsev mortar
Nrog cov viscosity siab thiab cov dej tuav tau zoo, cov tshuaj khib nyiab tsis yooj yim rau poob tshauv thiab sag, uas txhim kho kev tsim kho.
Feem ntau hais lus, qhov siab dua qhov viscosity, qhov dej tuav tau zoo dua, yog li ntau tus neeg siv khoom yuav xaiv siv nruab nrab-viscosity cellulose (75,000-100,000) es tsis txhob nruab nrab-tsawg viscosity cellulose (20,000-50,000) kom txo cov nyiaj ntxiv, thiab tom qab ntawd tswj tus nqi
