Ni gute wamenya ingano y'ivu rya hydroxypropyl methylcellulose?

Ivu ririmo ni ikimenyetso cy'ingenzi cy'ukohydroxypropyl methylcellulose. Abakiriya benshi bakunze kwibaza niba basobanukiwe na hydroxypropyl methylcellulose: agaciro k'ivu ni akahe? Hydroxypropyl methylcellulose ifite ivu rito bivuze ko ifite ubuziranenge bwinshi; cellulose ifite ivu rinini bivuze ko hari imyanda myinshi irimo, ibyo bizagira ingaruka ku ngaruka zo gukoreshwa cyangwa bikongera ingano y'inyongera. Iyo abakiriya bahisemo hydroxypropyl methylcellulose, bakunze gucana cellulose n'umuriro bakayitwika kugira ngo bapime ingano y'ivu riri muri cellulose. Ariko ubu buryo bwo kuyimenya ntibujyanye na siyansi, kuko abakora benshi bongeramo ibintu byihutisha umuriro muri cellulose. Ku buso, cellulose ifite ivu rito cyane nyuma yo gutwika, ariko mu by'ukuri, kubika amazi kwa hydroxypropyl methylcellulose ntabwo ari byiza cyane.

None se ni gute twamenya neza ingano y'ivu rya hydroxypropyl methylcellulose? Uburyo bwiza bwo kumenya ni ugukoresha itanura ridafite ifuru kugira ngo tumenye.

Ingano y'ibikoresho byo gusesengura, itanura rishyushye cyane, itanura rikoresha amashanyarazi.

Uburyo bwo gukora igerageza:

1) Ubwa mbere, shyira icyuma cya porcelain cya mililitiro 30 mu itanura rishyushye cyane hanyuma ugitwike kuri (500~600) °C mu gihe cy'iminota 30, funga irembo ry'itanura kugira ngo ugabanye ubushyuhe mu itanura kugeza munsi ya 200 °C, hanyuma ukuremo icyuma cya porcelain hanyuma ukijyane mu cyuma gikonjesha (iminota 20~30), upime.

2) Gupima 1.0 g yahydroxypropyl methylcelluloseku gipimo cy’isesengura, shyira icyitegererezo cyapimwe mu cyuma gikonjesha, hanyuma ushyiremo icyuma gikonjesha kirimo icyitegererezo ku itanura ry’amashanyarazi kugira ngo gikonjeshe kugeza ku bushyuhe bw’icyumba, ongeramo aside sulfure (0.5-1.0 ml), hanyuma ugishyire ku itanura ry’amashanyarazi kugira ngo gikonjeshe burundu. Hanyuma wimurire ku itanura ry’igenzura ry’ubushyuhe bwinshi, utwike kuri (500 ~ 600 ℃) mu gihe cy’isaha 1, uzimye imbaraga z’itanura ry’igenzura ry’ubushyuhe bwinshi, igihe ubushyuhe bw’itanura bugabanutse munsi ya 200 ℃, kuraho uyishyire mu cyuma gikonjesha kugira ngo ikonje (iminota 20 ~ 30), hanyuma uyipime ku gipimo cy’isesengura.

Kubara Ibisigazwa by'umuriro bibarwa hakurikijwe formula (3):

Muri formula: m1 – uburemere bw'icyuma kirimo ubusa, muri g;

m2 – uburemere bw'ibisigazwa n'ibicanwa, muri g;

m – uburemere bw'icyitegererezo, muri g.
