Menene matakan kariya don auna danko na hydroxypropyl methyl celluloseHPMC? Lokacin da muka gwada danko na cellulose. Domin tabbatar da daidaiton sakamakon gwajin, ya kamata a ba da kulawa ta musamman ga abubuwa hudu masu zuwa.
1. Ma'anar aikin kayan aiki dole ne su cika bukatun ka'idojin tabbatar da awo na ƙasa.
Thehydroxypropyl methyl celluloseAna amfani da kayan auna danko a cikin zagayowar gwaji. Idan ya cancanta (ana amfani da kayan aiki akai-akai ko a cikin mawuyacin yanayin cancanta), ana yin gwajin kai na tsaka-tsaki don tabbatar da cewa aikin auna ya cancanci kuma kuskuren ƙididdiga yana cikin kewayon da aka yarda, in ba haka ba ba za a iya samun cikakkun bayanai ba.
2. Kula da hankali na musamman ga yanayin zafin ruwa da ake aunawa.
Yawancin masu amfani sun yi watsi da wannan kuma suna tunanin cewa zafin jiki kusan ba shi da mahimmanci. Gwaje-gwajenmu sun nuna cewa: lokacin da yanayin zafin jiki ya kasance 0.5 ℃, bambancin danko na wasu ruwaye ya fi 5%. Matsakaicin zafin jiki yana da tasiri mai girma akan danko, zafin jiki da danko. Don haka, ya kamata a kula da yanayin zafin ruwa da aka auna kusa da wurin da aka ƙayyade, kuma don auna daidai, yana da kyau kada ya wuce 0.1 ℃.
3. Zaɓin akwati mai aunawa (bututu na waje).
Don na'urorin jujjuyawar ganga biyu, karanta jagorar kayan aiki a hankali kuma daidaita na'urar rotor (Silinda ta ciki) daidai da haka. Silinda na waje, in ba haka ba sakamakon auna zai zama mai karkata sosai. Don viscometer juyi guda ɗaya, radius na silinda na waje ya kamata ya zama marar iyaka bisa ƙa'ida. Ma'auni na ainihi yana buƙatar cewa diamita na ciki na silinda na waje bai zama ƙasa da ƙayyadaddun girman ba. Misali, NDJ-1 rotary viscometer yana buƙatar ma'aunin ma'aunin beaker ko kwandon bututu madaidaiciya wanda bai gaza mm 70 a diamita ba. Gwaje-gwaje sun nuna cewa manyan kurakuran ma'auni na iya haifar da idan diamita na ciki na jirgin ya yi ƙanƙanta sosai, musamman lokacin rotor no. Ana amfani da 1.

Wannan nau'in kayan aikin yana amfani da bugun bugun kira tare da karatun mai nuni, kuma haɗin kwanciyar hankali da karkatar karatu yana da grid 0.5. Idan karatun ya yi ƙanƙanta, yana gabatowa grid 5, kuskuren dangi zai iya zama fiye da 10%. Idan an zaɓi madaidaicin rotor ko karatun saurin shine 50, ana iya rage kuskuren dangi zuwa 1%. Idan darajar ta nuna sama da 90, karfin jujjuyawar da bazara ta haifar yana da girma sosai, wanda ke da saurin ratsawa da lalata gashin gashi, don haka dole ne mu zaɓi rotor da sauri daidai.
Wannan takarda ta gabatar da abubuwan da ke buƙatar kulawa wajen auna danko na hydroxypropyl methyl cellulose, da fatan abin da ke sama zai iya taimaka maka gwadawa.KIMA CHEMICALya bi ka'idar "bidi'a, abokin ciniki na farko, inganci na farko".
