Uburyo bworoshye bwo kumenya hydroxypropyl methylcellulose

Cellulose ikoreshwa cyane muri peteroli, ubuvuzi, gukora impapuro, kwisiga, ibikoresho byubwubatsi, nibindi. Byongeweho byinshi, kandi imikoreshereze itandukanye ifite imikorere itandukanye kubicuruzwa bya selile.

Iyi ngingo itangiza cyane cyane uburyo bwo kumenya no kumenya ubuziranenge bwa HPMC (hydroxypropyl methylcellulose ether), ubwoko bwa selile bukunze gukoreshwa mu ifu isanzwe.

HPMC ikoresha ipamba inoze nkibikoresho nyamukuru.Ifite imikorere myiza, igiciro kinini kandi irwanya alkali nziza.Irakwiriye kubisanzwe birwanya amazi na polymer minisiteri ikozwe muri sima, calcium ya lime nibindi bikoresho bikomeye bya alkaline.Urwego rwa viscosity ni 40.000-200000S.

Ibikurikira nuburyo bwinshi bwo gupima ubuziranenge bwa hydroxypropyl methylcellulose yavuzwe na Xiaobian kubwawe.Ngwino wige na Xiaobian ~

1. Umweru:

Birumvikana ko ikintu gikomeye mu kumenya ubwiza bwa hydroxypropyl methylcellulose ntigishobora kuba umweru gusa.Bamwe mubakora ibicuruzwa bazongeramo ibikoresho byera mugikorwa cyo kubyara, muriki gihe, ubuziranenge ntibushobora gucirwa urubanza, ariko umweru wa hydroxypropyl methylcellulose wo mu rwego rwo hejuru ni mwiza rwose.

2. Ubwiza:

Hydroxypropyl methylcellulose mubusanzwe ifite ubwiza bwa mesh 80, mesh 100 na mesh 120.Ubwiza bwibice nibyiza cyane, kandi gukomera no gufata amazi nabyo nibyiza.Iyi ni hydroxypropyl methylcellulose yo mu rwego rwo hejuru.

3. Kohereza urumuri:

Shira hydroxypropyl methylcellulose mumazi hanyuma uyishongeshe mumazi mugihe runaka kugirango urebe ubwiza nubucyo.Gele imaze gushingwa, genzura itara ryayo, nibyiza kohereza urumuri, niko ibintu bitangirika kandi byera.

4. Uburemere bwihariye:

Ninini nini ya rukuruzi yihariye, nibyiza, kuko uburemere buremereye bwihariye, niko ibirimo hydroxypropyl methyl irimo, niko gufata amazi neza.
