Ni ubuhe bwenge bwa hydroxypropyl methylcellulose hpmc?

Ifu yuzuye kurukuta rwimbere muri rusange ifite ubwiza bwa 100.000. Isima ya sima ifite ibisabwa byinshi kugirango ihindurwe, kandi ubwiza bwa 150.000 biroroshye gukoresha. Mubyongeyeho, uruhare rukomeye rwa HPMC nugufunga amazi, hagakurikiraho kubyimba. Ifu ya putty, niba gufata amazi ari byiza kandi ubukonje buri hasi (7-80,000), burashobora kandi kugira ubwiza buhebuje ndetse no kubika amazi neza. Iyo ibishishwa birenga 100.000, ibishishwa ntacyo bigira ku gufata amazi.

Ni izihe ngaruka zingenzi zaHPMC mu ifu yuzuye, kandi niba chimie organic ibaho?

HPMC ikina imirimo itatu yo kubyimba, kubika amazi no kubaka ifu yuzuye.

Kubyimba: Methylcellulose irashobora guhurizwa hamwe no kureremba, amazi yo mumazi kugirango agumane imikorere imwe kandi ihamye kandi irinde kumanuka.

Kubika amazi: Ifu y'urukuta rw'imbere yumye gahoro, kandi kongeramo calcium ya calcium bigaragarira mugukoresha amazi.

Ubwubatsi bwubwubatsi: Methyl selulose ifite amavuta yo gusiga, ashobora gutuma ifu ya putty igira imiterere myiza yubuhanga.

HPMC ntabwo igira uruhare mubihinduka byose byimiti ahubwo byiyongera. Ifu ya putty, kurukuta, ni impinduka yimiti, kubera ko hari ibintu bishya bihindura imiti, ifu ya putty isohoka kurukuta, igasya ifu, ikongera ikakoreshwa kuko hashyizweho ibintu bishya byimiti (calcium karubone).

Ibyingenzi byingenzi bigize isazi ya calcium ni: Ca (oh) 2, Cao hamwe nuduke duto twa Caco3, Caoh2oCa (oh) 2-Ca (oh) 2caco3h2o lime irashobora guhinduka calcium bicarbonate mumazi na gaze, mugihe mpc ari gusa amazi ashonga Kalisiyumu isazi ivu nigitekerezo gikomeye, ubwacyo ntigire uruhare mubitekerezo byose.

Ni iki gikwiye kwitabwaho mugushira mubikorwa isano iri hagati yubukonje nubushyuhe bwa HPMC?

Ubukonje bwa HPMC buringaniye n'ubushyuhe, mu yandi magambo, ubukonje bwiyongera hamwe n'ubushyuhe bugabanuka. Ubukonje bwibicuruzwa, ubwiza bwibicuruzwa bivuze ko igisubizo cyacyo 2% kiri ku bushyuhe bwa dogere selisiyusi 20, nibisubizo byikizamini.

Mubisabwa byihariye, hagomba kwitonderwa ahantu hafite itandukaniro rinini ryubushyuhe hagati yizuba nimbeho, kandi birasabwa cyane gukoresha ubukonje buke mugihe cy'itumba. Bitabaye ibyo, ibishishwa biri hasi, ubwiza bwa selile buziyongera, kandi ibishushanyo bizaba biremereye.

Ubucucike buciriritse: 75000-100000 bubereye ifu yuzuye
Impamvu: gufata neza amazi

Ubukonje bwinshi: 150000-200000 burakwiriye kubutaka bwa polystirene hamwe na minisiteri idasanzwe.
Impamvu: ubukonje bwinshi, kuvanaho sima ya sima, gutakaza gloss, kubaka neza.
