Matsaloli a cikin amfani da methyl cellulose

Methyl cellulose shine raguwar sodium carboxymethyl cellulose. An fi amfani da shi a cikin abinci, gini, magunguna, yumbu, batura, hakar ma'adinai, sutura, yin takarda, wanki, man goge baki na yau da kullun, bugu da rini, haƙon mai da sauransu a cikin filin. Babban aikin shine yin aiki azaman mai kauri, wakili mai riƙe ruwa, mai ɗaure, mai mai, wakili mai dakatarwa, emulsifier, mai ɗaukar samfuran halitta, matrix na kwamfutar hannu, da dai sauransu. Yaya za a daidaita methyl cellulose yayin amfani?

1. Methylcellulose kanta shine fari busassun foda, wanda ba za a iya amfani da shi kai tsaye a cikin masana'antu ba. Ana buƙatar a narkar da shi a cikin ruwa da farko don samar da manne mai haske kafin a iya haɗa shi da turmi sannan a yi amfani da shi don wasu magunguna, kamar manna tayal.

2. Menene rabon methyl cellulose? Foda: ruwa yana buƙatar sarrafa lokaci guda bisa ga rabo na 1: 150-200, sa'an nan kuma a motsa shi ta hanyar wucin gadi, yayin da ake ƙara PMC bushe foda yayin motsawa, kuma za'a iya amfani dashi bayan kimanin awa 1.

3. Idan an yi amfani da methyl cellulose don maganin haɗin gwiwa, manne rabo yana buƙatar bi → manne: ciminti = 1: 2.

4. Idan ana amfani da methyl cellulose a matsayin turmi siminti don tsayayya da tsagewa, ana buƙatar manne manne rabo → manne: ciminti: yashi = 1: 3: 6.

Muna buƙatar kula da wasu matsalolin yayin amfani da methyl cellulose:

1. Kafin yin amfani da methyl cellulose bisa ƙa'ida, dole ne ka fara duba ƙayyadaddun bayanai da samfura. Samfura daban-daban suna amfani da hanyoyi daban-daban: lokacin pH> 10 ko <5, danko na manne yana da ɗan ƙaramin ƙarfi. Ayyukan aiki shine mafi kwanciyar hankali lokacin pH = 7, kuma danko zai tashi da sauri lokacin da zafin jiki ya kasa 20 ° C; Lokacin da zafin jiki ya wuce 80 ° C, colloid za a hana shi bayan dumama tsawon lokaci, amma danko zai ragu sosai.

2. Methyl cellulose za a iya shirya da ruwan sanyi ko ruwan zafi bisa ga kayyade rabo. Lokacin shirya, kuna buƙatar ƙara ruwa yayin motsawa. Ka tuna don ƙara duk ruwa da PMC bushe foda a lokaci ɗaya. Yana da kyau a lura cewa tushen tushen da ake buƙatar haɗawa ya kamata a tsaftace shi a gaba, kuma wasu datti, dattin mai, da ƙananan yadudduka suna buƙatar magance su cikin lokaci.
