Dab tsi yog qhov tseem ceeb ntawm HPMC?
HPMC tuaj yeem muab faib ua: qib kev tsim kho, qib zaub mov thiab qib kho mob los ntawm kev siv.
HPMC yog dav siv hauv cov khoom siv hauv tsev, coatings, hluavtaws resins, ceramics, tshuaj, khoom noj khoom haus, textile, kev ua liaj ua teb, tshuaj pleev ib ce, luam yeeb thiab lwm yam lag luam.
Tam sim no, feem ntau ntawm cov qib kev tsim kho hauv tsev, hauv qib kev tsim kho, cov hmoov putty hmoov yog loj, li ntawm 90% yog siv los ua cov hmoov putty, tus so yog siv los ua cov cement mortar thiab kua nplaum.

Cov ntaub ntawv tseem ceeb ntawm HPMC yog dab tsi?
HPMC cov ntaub ntawv tseem ceeb: refined paj rwb, chloromethane, propylene oxide. Lwm cov ntaub ntawv raw yog, ntsiav tshuaj alkali, acid, toluene, isopropanol thiab lwm yam.

- HPMC muab faib ua ntau hom, qhov sib txawv ntawm kev siv yog dab tsi?
HPMC tuaj yeem muab faib ua hom instant thiab kub soluble.

Cov khoom lag luam tam sim no, hauv dej txias sai sai, ploj mus hauv dej, lub sijhawm no cov kua tsis muaj viscosity, vim tias HPMC tsuas yog tawg mus rau hauv dej, tsis muaj kev sib cais tiag tiag. Txog 2 feeb, cov viscosity ntawm cov kua maj mam nce, tsim cov pob tshab viscous colloid. Kev siv ntau yam, hauv cov hmoov putty thiab mortar, thiab kua kua nplaum thiab xim, tuaj yeem siv tau, tsis muaj kev txwv.

Cov khoom kub soluble, hauv dej txias, tuaj yeem tawg sai sai hauv dej kub, ploj mus hauv dej kub, thaum qhov kub thiab txias poob mus rau qee qhov kub, viscosity maj mam tshwm, kom txog rau thaum tsim cov pob tshab viscous colloid. Tsuas yog siv tau rau hauv cov hmoov putty thiab mortar, hauv cov kua nplaum thiab xim, yuav muaj ib pawg phenomenon, siv tsis tau.

Dab tsi yog lub ntsiab technical indicators, AsHPMC?
Hydroxypropyl cov ntsiab lus thiab viscosity, cov neeg siv feem ntau txhawj xeeb nrog ob qhov ntsuas no.

Hydroxypropyl cov ntsiab lus yog siab, dej tuav feem ntau zoo dua.

Viscosity, dej tuav, txheeb ze (tab sis tsis meej) kuj zoo dua, thiab viscosity, hauv cement mortar zoo dua siv qee yam.

Ntau npaum li cas viscosity haum rau HPMC?
Lub luag haujlwm tseem ceeb tshaj plaws ntawm HPMC yog kev tuav dej, ua raws li cov thickening.
Putty hmoov feem ntau yog 100000 cps tuaj yeem ua tau. Ntev npaum li cov dej tuav tau zoo, qhov viscosity tsawg (70,000-80000), kuj tseem ua tau, ntawm chav kawm, qhov viscosity loj dua, cov txheeb ze dej tuav tau zoo dua, thaum lub viscosity ntau dua 100,000, viscosity muaj. me ntsis cuam tshuam rau kev tuav dej.
Qhov yuav tsum tau muaj nyob rau hauv MORTAR yog qee qhov siab dua, XAV NTAU NTAU 150 THOUSAND tsuas yog siv tau zoo.
Daim ntawv thov kua nplaum: xav tau cov khoom lag luam sai, siab viscosity.
