Hydroxypropyl methyl cellulose tau siv los ua cov hmoov nplej
Nrog kev siv thiab nkag siab ntawmHPMChydroxypropyl methyl cellulose, Kuv paub tseeb tias ntau ntawm koj paub tias putty hmoov yog tam sim no pib ntxiv rau nws. Niaj hnub no peb yuav tsum nkag siab txog kev siv hydroxypropyl methyl cellulose putty hmoov muaj nuj nqi.
Thickening: tuaj yeem ua kom tuab thiab tshem tawm, kom cov tshuaj sib xyaw ua ke, tiv thaiv dej dai.
Kev tuav dej: putty hmoov qhuav maj mam, auxiliary calcium calcium nyob rau hauv qhov kev txiav txim ntawm cov tshuaj tiv thaiv dej.
Txhim kho kev ua tau zoo: cov hmoov putty muaj cov qauv zoo vim nws txoj haujlwm lubrication. Nws tsis koom nrog cov tshuaj tiv thaiv tshuaj, tsuas yog ua lub luag haujlwm txhawb nqa. Putty hmoov ntxiv dej rau phab ntsa. Nws yog tshuaj chemical. Raws li cov ntaub ntawv tshiab, cov hmoov putty yog muab tso rau ntawm phab ntsa ntawm phab ntsa, hauv av rau hauv cov hmoov, thiab tom qab ntawd siv raws li nws tau tsim cov khoom tshiab (calcium carbonate). ) Cov khoom tseem ceeb ntawm grey calcium hmoov yog: Ca (OH) 2, CaO thiab ib qho me me ntawm CaCO3 sib tov, CaO + H2O = Ca (OH) 2-CA (OH) 2 + CO2 = CaCO3 + dej thiab carbon dioxide hauv huab cua tsim cov nyhuv ntawm calcium carbonate, thiab HPMC tsuas yog dej, pab grey calcium zoo dua cov tshuaj tiv thaiv, nws tsis tau koom nrog cov tshuaj tiv thaiv.
Cov saum toj no yog siv cov hmoov putty. Yog tias txhua tus neeg txaus siab rau cov khoom no, lawv tuaj yeem tuaj rau peb. Raws li tus khub txhim khu kev qha, peb ib txwm ua raws li "kev tsim kho thev naus laus zis raws li kev tsav tsheb, cov neeg siv khoom yog qhov chaw, kom muaj txiaj ntsig zoo, lub koob npe nrov thiab kev loj hlob" lub tswv yim kev lag luam, niaj hnub tsim khoom siv thiab thev naus laus zis, mus rau lub hom phiaj ntsuab thiab high-tech. .
Tiantai Cellulose txaus siab rau cov khoom lag luam zoo thiab cov khoom lag luam zoo, kev koom tes nrog kev koom tes, kev txhim kho mus ntev.
