Idan ya zo ga solubility na methyl cellulose, yafi nufin solubility na sodium carboxymethyl cellulose.
Sodium carboxymethyl cellulose fari ne ko rawaya foda na fiber foda, wanda ba shi da wari kuma mara daɗi. Yana da sauƙi mai narkewa a cikin sanyi ko ruwan zafi, yana samar da bayani mai haske tare da wani danko.
Menene solubility? A gaskiya ma, yana nufin adadin solute da wani abu mai ƙarfi ya narkar da shi a cikin ingantacciyar yanayi a cikin 100g na sauran ƙarfi a wani zazzabi. Wannan shine solubility. Solubility na methyl cellulose yana da alaƙa da bangarori biyu. A daya hannun, shi ya dogara da halaye na carboxymethyl cellulose, da kuma a daya hannun, shi yana da kadan dangantaka da waje zafin jiki, zafi, matsa lamba, sauran ƙarfi irin, da dai sauransu The solubility na carboxymethyl cellulose yawanci ya fi a fili shafi ta zafin jiki, kuma zai karu tare da karuwar zafin jiki.
Akwai hanyoyi guda uku na narkar da methylcellulose:
1. Organic ƙarfi jika hanyar. Wannan hanyar ita ce ta fi tarwatsa ko jika abubuwan kaushi na MC irin su ethanol da ethylene glycol a gaba, sannan a kara ruwa don narkewa.
2. Hanyar ruwan zafi. Saboda MC ba ya narkewa a cikin ruwan zafi, ana iya rarraba MC daidai a cikin ruwan zafi a matakin farko. Lokacin sanyaya, ana iya bin hanyoyi biyu masu zuwa:
(1) Zaku iya fara ƙara adadin ruwan zafi mai dacewa a cikin akwati kuma kuyi zafi zuwa kimanin 70 ° C. An kara MC a hankali tare da motsawa a hankali, a hankali yana samar da slurry, wanda aka sanyaya tare da motsawa.
(2) Ƙara 1/3 na adadin ruwan da ake buƙata a cikin wani madaidaicin akwati, zafi shi zuwa 70 ° C, kuma watsar da MC bisa ga hanyar da aka ambata, sa'an nan kuma shirya slurry ruwan zafi; sai a zuba a ruwan sanyi Je zuwa ga slurry, sai a motsa sosai sannan a huce hadin.
3. Hanyar hada foda. Wannan hanyar ita ce ta tarwatsa ɓangarorin foda na MC da sinadarai daidai gwargwado ta hanyar busassun hadawa, sannan a ƙara ruwa don narkewa.
