Koj puas paub hydroxypropyl methylcellulose?

Hydroxypropyl methylcellulose yog siv dav hauv kev tsim kho kev lag luam. Hnub no, kuv yuav qhia txog txoj kev sib cais ntawm hydroxypropyl methylcellulose thiab yuav ua li cas txiav txim qhov zoo ntawm hydroxypropyl methylcellulose.

Txoj kev ntawm dissolving hydroxypropyl methylcellulose:

Txhua tus qauv tuaj yeem muab ntxiv rau cov khoom siv los ntawm kev sib xyaw qhuav;

Thaum nws yuav tsum tau ntxiv ncaj qha mus rau qhov kub thiab txias aqueous tov, nws yog qhov zoo tshaj plaws los siv cov dej txias dispersion hom, thiab nws tuaj yeem thicken li ntawm 10-90 feeb tom qab ntxiv;

Tom qab stirring thiab dispersing nrog dej kub rau hom, ntxiv dej txias thiab do kom dissolve nws;

Yog hais tias muaj agglomeration thiab txheej thaum lub sij hawm dissolution, nws yog tshwm sim los ntawm tsis txaus stirring los yog ncaj qha ntxiv cov dej txias rau cov zoo tib yam profiles. Lub sijhawm no, nws yuav tsum tau nplawm sai sai;

Yog tias cov npuas raug tsim tawm thaum lub sijhawm tawg, lawv tuaj yeem raug tso tseg rau 2-12 teev (txiav txim siab raws li qhov sib xws ntawm cov tshuaj) los yog tshem tawm los ntawm kev khiav tawm, kev tawm dag zog, thiab lwm yam, thiab qhov tsim nyog ntawm defoamer tuaj yeem ntxiv.

Yuav ua li cas txiav txim qhov zoo ntawm hydroxypropyl methylcellulose yooj yim thiab intuitively

Whiteness: Raws li kev ua kom dawb, nws tsis tuaj yeem txiav txim siab seb HPMC tuaj yeem siv li cas, thiab yog tias cov tshuaj ntxuav hniav dawb ntxiv rau hauv cov txheej txheem tsim khoom, nws tseem yuav cuam tshuam rau nws qhov zoo. Txawm li cas los xij, cov khoom lag luam nrog cov xim dawb yog feem ntau zoo.

Fineness: HPMC feem ntau yog 80 mesh, 100 mesh, 120 mesh, qhov zoo dua qhov zoo dua.

Transmittance: muab HPMC tso rau hauv dej los tsim cov pob tshab colloid, thiab saib nws qhov kev xa tawm. Qhov ntau dua qhov kev xa tawm, cov tshuaj insoluble tsawg dua hauv dej. Feem ntau, qhov kev xa tawm tau zoo dua nyob rau hauv ntsug reactors thiab kab rov tav reactors. Nws yog qhov phem dua nyob rau hauv lub reactor ntsug, tab sis nws tsis tuaj yeem piav qhia tias qhov zoo ntawm cov khoom tsim los ntawm cov reactor ntsug yog zoo dua li ntawm cov kab rov tav reactor.

Lub ntiajteb txawj nqus tshwj xeeb: Feem ntau hais lus, vim muaj cov ntsiab lus hydroxypropyl siab, cov dej tuav tau zoo.
