Nigute ushobora kumenya ibikubiye ivu rya hydroxypropyl methylcellse?

Ibirimo ni ikintu cyingenzi cyahydroxypropyl methylcellse. Abakiriya benshi bakunze kubaza iyo basobanukiwe hydroxypropyl methylcellse: Agaciro kangana iki? HydroxyPropyl Methylcellse hamwe ninvu ntoya bisobanura ubuziranenge; Cellulose hamwe ninshi ikubits bivuze ko hariho impanda nyinshi zirimo, zizagira ingaruka kumikoreshereze cyangwa kongera umubare wiyongera. Iyo abakiriya bahisemo HydroxyPropyl Methylcellse, akenshi bacana muburyo butaziguye na selile numuriro bakayitwika kugirango barebe ibikubiye muri selile. Ariko ubu buryo bwo kumenya ntabwo ari siyansi, kuko abakora benshi bongera kunyereza hamwe na selile. Ku buso, selile ifite ivu rito nyuma yo gutwika, ariko mubikorwa, kugumana amazi ya hydroxyPropyl methylcellse ntabwo ari byiza cyane.

None dukwiye kumenya dute ibikubiye ivu rya hydroxyproppopyl methylcellse? Uburyo bukwiye bwo kumenya ni ugukoresha itanura rya muffle kugirango tumenye.

Igikoresho gisesengura uburimbane, ubushyuhe bwinshi muffle itanura, itanura ryamashanyarazi.

Uburyo bwo kugerageza:

1) Ubwa mbere, shyiramo 30ml Porcelain Crucle Itara Kumurongo hanyuma uyitwike kuri (500 ~ 600) ° Cintama iminota 30, funga Irembo ryitanura kugirango ugabanye ubushyuhe muri itanura kugera munsi ya 200 ° C, hanyuma ufate Hanze kandi uyimure kuri desiccator kugirango ukonje (20 ~ 30) min, gupima.

2) ipima 1.0 g yahydroxypropyl methylcellseKu buringanire bwo gusesengura, shyira icyitegererezo cyapimwe mubintu bikaba, hanyuma ushireho ibitambaro byamashanyarazi, ongeraho acide ya sulfuric (0.5-1.0) Karuboni yuzuye. Noneho wimuke hejuru yubushyuhe bwa muffle itanura, gutwika kuri (500 ~ 600) ℃ kumasaha 1, zimya imbaraga zubushyuhe bwo hejuru, mugihe itanura ryubushyuhe rigabanuka munsi ya 200 ℃, tuyikuramo kandi tuyishyire muri desiccator Gukonjesha (20 ~ 30) min, hanyuma upimirwa ku buringanire.
