Gwajin Danko na Cellulose Ether

Danko naƙwayoyin cellulose, kamar Hydroxypropyl Methylcellulose (HPMC) ko Carboxymethyl Cellulose (CMC), muhimmin siga ne wanda zai iya shafar aikinsu a aikace-aikace daban-daban. Danko shine ma'aunin juriyar ruwa ga kwarara, kuma abubuwa kamar yawan abu, zafin jiki, da kuma matakin maye gurbin cellulose ether na iya shafar shi.

Ga jagorar gabaɗaya kan yadda za a iya gudanar da gwaje-gwajen danko don ƙwayoyin cellulose:

Hanyar Mai auna sigina ta Brookfield:

Na'urar auna sinadari ta Brookfield wani kayan aiki ne da ake amfani da shi wajen auna dankowar ruwa. Matakan da ke ƙasa suna ba da cikakken bayani game da yadda ake gudanar da gwajin danko:

1. Samfurin Shiri:

2. Daidaiton Zafin Jiki:
   • Tabbatar cewa samfurin ya daidaita da zafin gwajin da ake so. Danko zai iya dogara da zafin jiki, don haka gwaji a zafin da aka sarrafa yana da mahimmanci don ma'auni daidai.
3. Daidaitawa:
   • Daidaita viscometer na Brookfield ta amfani da ruwa mai daidaitawa na yau da kullun don tabbatar da daidaiton karatu.
4. Loda Samfurin:
   • A zuba isasshen adadin maganin cellulose ether a cikin ɗakin viscometer.
5. Zaɓin Spindle:
   • Zaɓi sandar da ta dace bisa ga kewayon danko da ake tsammani na samfurin. Akwai sandunan juyawa daban-daban don kewayon danko mai ƙanƙanta, matsakaici, da babban.
6. Aunawa:
   • A nutsar da madaurin a cikin samfurin, sannan a fara amfani da na'urar auna sigina (viscometer). Madaurin yana juyawa a daidai gwargwado, kuma ana auna juriyar juyawa.
7. Bayanan Rikodi:
   • Yi rikodin karatun danko daga allon viscometer. Naúrar aunawa yawanci tana cikin centipoise (cP) ko millipascal-seconds (mPa·s).
8. Maimaita Ma'auni:
   • A yi ma'auni da yawa domin tabbatar da sake haifuwa. Idan danko ya bambanta da lokaci, ana iya buƙatar ƙarin ma'auni.
