Hydroxypropyl methyl cellulose tau siv ua hmoov putty
Nrog kev siv thiab kev nkag siab ntawmHPMChydroxypropyl methyl cellulose, kuv paub tseeb tias ntau tus ntawm nej paub tias cov hmoov putty tam sim no yeej ntxiv rau nws. Niaj hnub no peb yuav tsum nkag siab txog kev siv hydroxypropyl methyl cellulose putty hmoov ua haujlwm.
Thickening: tuaj yeem ua kom tuab thiab ncua, yog li ntawd cov tshuaj sib xws, tiv thaiv kev ntws dai.
Kev khaws dej: hmoov putty qhuav qeeb qeeb, pabcuam calcium calcium hauv qhov kev ua ntawm cov tshuaj tiv thaiv dej.
Txhim kho kev ua haujlwm: cov hmoov putty muaj cov qauv zoo vim nws lubrication ua haujlwm. Nws tsis koom nrog hauv kev tshuaj lom neeg, tsuas yog ua lub luag haujlwm txhawb nqa. Cov hmoov putty ntxiv dej rau ntawm phab ntsa. Nws yog kev tshuaj lom neeg. Thaum cov tshuaj tshiab tsim, cov hmoov putty raug muab tso rau ntawm phab ntsa ntawm phab ntsa, zom ua hmoov, thiab tom qab ntawd siv vim nws tau tsim cov tshuaj tshiab (calcium carbonate). ) Cov khoom tseem ceeb ntawm cov hmoov calcium grey yog: Ca (OH) 2, CaO thiab me me ntawm CaCO3 sib tov, CaO + H2O = Ca (OH) 2-CA (OH) 2 + CO2 = CaCO3 + dej thiab carbon dioxide hauv huab cua los tsim cov nyhuv ntawm calcium carbonate, thiab HPMC tsuas yog dej, pab cov calcium grey zoo dua, nws tsis tau koom nrog hauv kev tshuaj lom neeg.
Qhov saum toj no yog kev siv cov hmoov putty. Yog tias txhua tus neeg xav tau cov khoom no, lawv tuaj yeem tuaj rau peb. Ua tus khub txhim khu kev qha, peb ib txwm ua raws li "kev tsim kho tshiab thev naus laus zis ua lub zog tsav tsheb, cov neeg siv khoom ua lub hauv paus, rau qhov zoo ntawm kev ciaj sia, lub koob npe nrov thiab kev txhim kho" lub tswv yim kev txhim kho lag luam, tsis tu ncua tsim cov khoom siv thiab thev naus laus zis, mus rau ntsuab thiab cov hom phiaj siab.
Tiantai Cellulose txaus siab rau cov khoom zoo thiab cov khoom zoo, kev koom tes ua siab dawb, kev txhim kho mus sij hawm ntev.
