Hydroxypropyl Methyl Cellulose (HPMC) Siv rau Xim Dej

Peb cov cellulose ether dej khaws cia kev ua tau zoo rau latex txheej, tshwj xeeb tshaj yog PVA txheej siab muab kev ua tau zoo heev, txheej rau cov pulp tuab, yuav tsis tsim flocculation; Nws cov nyhuv thickening siab tuaj yeem txo qhov koob tshuaj, txhim kho kev lag luam ntawm cov mis, thiab txhim kho kev ncua ntawm lub txheej txheej. Cov khoom zoo heev rheological hauv lub txheej, tuaj yeem nyob rau hauv lub xeev zoo li qub, khaws qhov zoo tshaj plaws thickening xeev ntawm lub txheej; Hauv lub xeev pov tseg, nrog zoo heev fluidity, thiab yuav tsis splash; Hauv lub txheej thiab cov menyuam txheej, yooj yim rau kis hauv lub substrate, yooj yim tsim kho; Thaum lub txheej tiav lawm, qhov viscosity ntawm lub kaw lus yuav rov qab los tam sim ntawd, lub txheej yuav tam sim ntawd tsim dej ntws.

Hauv lub ntiaj teb muaj zog heev ntawm cov xim pleev xim latex uas yog dej, ib qho khoom siv tseem ceeb heev yog Hydroxy Propyl Methyl Cellulose.(HPMC)Ntxiv rau qhov ua ib qho thickener ua haujlwm tau zoo heev, hom additive no kuj muab ntau yam khoom zoo, xws li txhuam-muaj peev xwm, sag tsis kam, emulsification, suspension zog, thiab lwm yam, thaum muab cov xim zoo heev-compatibility,thiabua rau hom thickener no nrov heev nrog ntau lub tuam txhab tsim xim hauv ntiaj teb.

Siv rau hauv cov xim pleev xim dej. Nws qhia tau tias nws cov nyhuv tuab zoo heev,thiabCov khoom rheological, dispersion thiab solubility. Nws muaj bio-stability zoo, muab sijhawm txaus rau cov xim khaws cia. Tiv thaiv cov pigments thiab filler sedimentation.
