Cov kws qhia txog cellulose yog chav kawm ntawm polymer kev hloov kho ntawm cov ntaub ntawv siv tshuaj lom neeg, cov tshuaj, khoom noj khoom haus, khoom noj khoom haus, khoom noj. Cov yam ntxwv ntawm cellulose muaj kev hais txog ze rau hom kev hloov pauv, qib hloov pauv thiab hnyav hnyav. Lawv muaj cov yam ntxwv tshwj xeeb thiab ntau yam kev siv.
1. Cov khoom ntawm cellulose muaj cov neeg muaj cai
So
Vim cov lus qhia ntawm cov neeg muaj kev cuam tshuam ntawm hydrogen hydrogen uas muaj zog heev ntawm thiab hauv cov txiv ntoo hauv qab, ua rau lawv soluble hauv dej lossis cov kuab tshuaj organic. Ntau hom ntawm cov cellulose muaj cov neeg hais ua lwm yam txawv solubility:
HydroxyPropyyl methylulose (HPMC): soluble hauv dej txias, insoluble hauv dej kub, tab sis cov khoom gel hauv dej kub.
Carboxymethyl cellulose (CMC): yooj yim soluble hauv dej txias thiab dej kub, nrog cov khoom siv thicking zoo.
Thickening thiab rheology
Tom qab dissolving, cellulose hais kom txaus ua lub siab-viscoority daws nrog cov nyhuv zoo heev. Nws rheological tus cwj pwm tuaj yeem hloov pauv nrog kev hloov pauv thiab cov kab mob shear, uas yog qhov tsim nyog rau kev kho kom zoo nkauj thiab ruaj khov ntawm cov qauv kev lag luam.
Zaj duab xis-tsim thiab nplaum cov khoom
Cov neeg hais ua ke cellulose tuaj yeem tsim cov yeeb yaj kiab sib txawv ntawm cov ntug ntawm substrate, nrog rau kev siv ua cov tshuaj pleev thiab cov khoom ntim. Nyob rau tib lub sijhawm, nws muaj cov nplaum nplaum thiab tuaj yeem siv ua phau ntawv.
Ruaj khov
Cellulose Cov neeg muaj kev hais ua neeg nyob ruaj khov nyob rau hauv cov xovtooj dav dav thiab muaj cov kua qaub muaj zog thiab alkali tsis kam. Nyob rau tib lub sijhawm, nws cov tshuaj lom neeg yog ruaj khov, tsis yooj yim degraded los ntawm cov kab mob me, thiab ua haujlwm tau ntev ntev.
Thermal Gelation
Qee cov cellulose muaj kev pab hais (xws li HPMC) yuav ua rau kev daws teeb meem los ua Turnbid lossis gel thaum rhuab. Cov cuab yeej no tau siv dav hauv kev tsim kho thiab kev lag luam zaub mov.
2. Daim ntawv thov ntawm cellulose muaj kev ua
Tsev Cov Ntaub Ntawv Teb
Cov neeg muaj kev hais ua haujlwm cellulose feem ntau yog siv raws li cov tuab yaj kiab, dej khaws thiab khi hauv cov ntaub ntawv tsim. Nws cov dej zoo ua kev tsim kho cov khoom siv tsim kev tsim kho thiab cov khoom siv gypsum, ntev lub sijhawm ua haujlwm, thiab tiv thaiv cov kab nrib pleb. Daim ntaub ntawv tshwj xeeb suav nrog:
Caas cug: txhim kho los tiv thaiv sagging, txhim kho adhesion thiab kev tsim kho fluidity.
Pobzeb nplaum: txhim kho lub zog ua kom muaj zog thiab txhim kho kev tsim kho yooj yim.
Putty hmoov thiab gypsum khoom: txhim kho cov khoom tsim kho, txhim kho dej khaws cia thiab nto smoothness.
Kho tsev kho mob
Cov neeg hais txog cellulose tau siv dav hauv kev lag luam hauv lub tshuaj, feem ntau yog cov tshuaj ua kom ruaj ntseg cov neeg sawv cev, cov khoom siv tsis sib haum, cov khoom siv tso tawm txheej. Piv txwv li:
HydroxyPropyyl methylcellueculose (HPMC): Raws li cov khoom siv raw rau capsule plhaub, nws hloov pauv cov neeg tsis noj nqaij thiab hypoochlergenic xav tau.
Hydroxyethyl cellulose (HEC): Siv los npaj cov tshuaj thiab kev poob qis.
Kev Lag Luam Khoom Noj
Cov cellulose muaj kev hais ntxiv yog cov tshuaj ntxiv tseem ceeb hauv kev lag luam khoom noj, nrog cov ua haujlwm thickening, ruaj khov, emulsification thiab dej khaws cov teebmeem.
Siv hauv cov mis nyuj khov, cov kua ntses thiab jellies txhawm rau txhim kho cov saj thiab kev ruaj khov ruaj khov.
Siv los ua cov moisturizer nyob rau hauv cov khoom ci los tiv thaiv kev laus thiab tawg.
Txheej ci thiab inks
Cov cellulose muaj kev hais ua cov tuab thiab rheology tswj cov neeg sawv cev hauv cov kev lag luam txheej thiab kev ua kom tiv thaiv cov xim av. Nyob rau tib lub sijhawm, raws li kev ua yeeb yaj kiab zaj duab xis, nws txhim kho txheej txheej ua haujlwm.
Cov Khoom Siv Txhua Hnub
Hauv cov tshuaj ntxuav, cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej, cov neeg ua haujlwm hauv paus cellulose yog siv ua cov tuab thiab ua kom muaj stabilizers thiab stabilizers. Piv txwv li, hauv cov tshuaj txhuam hniav, carboxymethyl cellulose (CMC) tuaj yeem muab cov zoo sib xws thiab muab tshuaj txhuam ruaj khov.
Lwm daim teb
Cov neeg hais txog cellulose kuj tseem tuaj yeem siv rau kev ua liaj ua teb
Cellulose Cov neeg muaj kev hais ua ke ua lub luag haujlwm tseem ceeb hauv kev lag luam ntau yam nrog lawv cov haujlwm zoo thiab muaj ntau yam kev ua tau zoo. Nrog kev tsim kho cellulose txuas ntxiv ntawm cov khoom siv ether ether tshuab, nws cov npe thov txuas ntxiv thiab ua si lub luag haujlwm tseem ceeb hauv kev txhim kho kom ruaj khov thiab kev ua haujlwm ntsuab.
