A cikin tsarin samar da yumbu, danko na slurry glaze shine ma'auni mai mahimmanci, wanda kai tsaye ya shafi ruwa, daidaituwa, lalata da sakamako na ƙarshe na glaze. Domin samun sakamako mai kyau na glaze, yana da mahimmanci don zaɓar abin da ya daceCMC (Carboxymethyl Cellulose) a matsayin thickener. CMC wani fili ne na polymer na halitta wanda aka saba amfani dashi a cikin yumbu glaze slurry, tare da kauri mai kyau, kaddarorin rheological da dakatarwa.
1. Fahimtar buƙatun danko na slurry glaze
Lokacin zabar CMC, da farko kuna buƙatar fayyace buƙatun danko na glaze slurry. Daban-daban glazes da kuma samar da matakai da daban-daban bukatun ga danko na glaze slurry. Gabaɗaya magana, tsayi ko ƙananan danko na glaze slurry zai shafi fesa, gogewa ko tsoma glaze.
Low danko glaze slurry: dace da spraying tsari. Ƙananan danko na iya tabbatar da cewa glaze ba zai toshe bindigar feshi yayin fesa ba kuma yana iya samar da ƙarin suturar uniform.
Matsakaici danko glaze slurry: dace da tsoma tsari. Matsakaicin danko na iya sa glaze ya rufe saman yumbu a ko'ina, kuma ba shi da sauƙin sag.
High danko glaze slurry: dace da brushing tsari. High danko glaze slurry iya zama a kan surface na dogon lokaci, kauce wa wuce kima fluidity, don haka samun wani lokacin farin ciki Layer.
Saboda haka, zaɓi na CMC yana buƙatar dacewa da bukatun tsarin samarwa.
2. Dangantaka tsakanin thickening yi da danko na CMC
Ayyukan kauri na AnxinCel®CMC yawanci ana ƙaddara ta hanyar nauyin kwayoyin halitta, digiri na carboxymethylation da ƙari adadin.
Nauyin kwayoyin halitta: Mafi girman nauyin kwayoyin halitta na CMC, yana da karfi da tasiri mai kauri. Mafi girman nauyin kwayoyin halitta zai iya ƙara danko na maganin, don haka ya samar da slurry mai kauri yayin amfani. Don haka, idan ana buƙatar slurry mafi girma danko, ya kamata a zaɓi CMC mai nauyi mai girma.
Degree na carboxymethylation: Mafi girma da digiri na carboxymethylation na CMC, da karfi da ruwa solubility, kuma shi za a iya mafi yadda ya kamata tarwatsa a cikin ruwa don samar da mafi girma danko. CMC na yau da kullun suna da digiri daban-daban na carboxymethylation, kuma ana iya zaɓar nau'ikan da suka dace bisa ga buƙatun slurry na glaze.

Alal misali, a cikin yanayin zafi mai zafi, ruwa yana ƙafe da sauri, kuma ana iya buƙatar CMC mai ƙarancin danko don guje wa wuce gona da iri na glaze slurry. Akasin haka, yanayin ƙananan zafin jiki na iya buƙatar babban danko CMC don tabbatar da kwanciyar hankali da ruwa na slurry.
4. Zabi mai amfani da shirye-shiryen CMC
A cikin ainihin amfani, zaɓi da shirye-shiryen CMC suna buƙatar aiwatar da su gwargwadon matakai masu zuwa:
Zaɓin nau'in AnxinCel®CMC: Na farko, zaɓi nau'in CMC da suka dace. Akwai maki daban-daban danko na CMC akan kasuwa, wanda za'a iya zaɓa bisa ga buƙatun danko da buƙatun dakatarwa na slurry glaze. Alal misali, CMC low kwayoyin nauyi ya dace da glaze slurries bukatar low danko, yayin da high kwayoyin nauyi CMC ya dace da glaze slurries bukatar high danko.
Daidaita gwajin danko: Dangane da ƙayyadaddun buƙatun glaze slurry, adadin CMC da aka ƙara an daidaita shi ta hanyar gwaji. Hanyar gwaji ta gama gari ita ce ƙara CMC a hankali a auna danƙonta har sai an kai iyakar ɗanƙoƙin da ake so.
Kula da kwanciyar hankali na glaze slurry: Ana buƙatar barin slurry ɗin da aka shirya don tsayawa na wani lokaci don lura da kwanciyar hankali. Bincika don hazo, agglomeration, da sauransu. Idan akwai matsala, adadin ko nau'in CMC na iya buƙatar gyarawa.
Daidaita sauran additives: Lokacin amfaniCMC, Har ila yau, wajibi ne a yi la'akari da yin amfani da wasu additives, irin su masu rarrabawa, masu daidaitawa, da dai sauransu.
