Hydroxyethyl Methyl Cellulose (HEMC)

Hydroxyethyl methyl cellulose (HEMC) polymer ne mai narkewa da ruwa wanda aka samu daga cellulose. Yana da wani abu maras ionic, mara guba, kuma maras ƙonewa wanda aka yi amfani da shi sosai a masana'antu daban-daban da aikace-aikacen mabukaci. HEMC yana da ƙima don ikonsa na yin aiki azaman mai kauri, ɗaure, da gyaran rheology a samfuran da yawa.

Ana yin HEMC ta hanyar canza sinadarai na cellulose na halitta. A cikin wannan tsari, ana kula da zaruruwan cellulose tare da sodium hydroxide don samar da alkali cellulose. Ethylene oxide sa'an nan kuma ƙara zuwa cakuda, wanda ya amsa tare da cellulose don ƙirƙirar hydroxyethyl cellulose. A ƙarshe, ana ƙara methyl chloride zuwa cakuda don ƙirƙirar HEMC.

Ana amfani da HEMC a cikin aikace-aikace iri-iri, gami da gini, abinci, kulawar mutum, da magunguna. Ɗaya daga cikin abubuwan da ake amfani da shi na HEMC na farko shine a cikin gine-gine, inda ake amfani da shi a cikin kayayyaki daban-daban kamar busassun hadaddun turmi, kayan kwalliya, tile adhesives, da kayan gypsum.

A cikin busassun busassun turmi, ana amfani da HEMC azaman mai kauri, ɗaure, da wakili mai riƙe ruwa. Yana taimakawa wajen inganta aikin turmi kuma yana ba da damar sarrafa abubuwan da ke cikin ruwa. Wannan yana da mahimmanci saboda abun ciki na ruwa na turmi yana rinjayar daidaitonsa, saita lokaci, da ƙarfin ƙarshe.

A cikin kayan kwalliya, ana amfani da HEMC da farko azaman mai kauri da ɗaure. Bugu da ƙari na HEMC zuwa gaurayawan yana taimakawa wajen inganta aikin aiki na putty kuma yana ba da damar sarrafa abun ciki na ruwa. Hemc shima yana taimakawa hana rabuwa da abubuwa daban-daban a cikin abin da ke da samuwa, kuma yana inganta matsin lamba na putty ga subes.

A cikin mannen tayal, ana amfani da HEMC da farko azaman wakili mai riƙe ruwa. Bugu da ƙari na HEMC zuwa gaurayawan yana taimakawa wajen inganta aikin mannewa kuma yana ba da damar sarrafa abun ciki na ruwa. Hemc shima yana taimakawa wajen hana rabuwa da abubuwa daban-daban a cikin adhesive tsari, kuma yana inganta maddara na m ga subes.

A cikin samfuran gypsum, ana amfani da HEMC azaman mai kauri, ɗaure, da wakili mai riƙe ruwa. Yana taimakawa wajen inganta aikin samfurin gypsum kuma yana ba da damar sarrafa abun ciki na ruwa. Wannan yana da mahimmanci saboda abun ciki na ruwa na samfurin gypsum yana rinjayar lokacin saiti da ƙarfin ƙarshe.

A cikin samfuran abinci, ana amfani da HEMC azaman mai kauri, mai ƙarfi, da emulsifier. Ana amfani dashi a cikin nau'ikan kayan abinci daban-daban, gami da miya, tufa, da kayan kiwo. HEMC yana da daraja don ikonsa don inganta rubutu da kwanciyar hankali na waɗannan samfurori.

A cikin samfuran kulawa na sirri, ana amfani da HEMC azaman mai kauri, stabilizer, da emulsifier. Ana amfani da shi a cikin nau'ikan samfuran kulawa na mutum daban-daban, gami da shamfu, kwandishana, da kayan shafawa. HEMC yana da daraja don iyawarta don inganta rubutu da kwanciyar hankali na waɗannan samfurori.

A cikin magunguna, ana amfani da HEMC azaman ɗaure da tarwatsewa. Ana amfani da shi a cikin kayan aikin kwamfutar hannu don haɓaka ƙarfin injin kwamfutar hannu da kuma taimakawa cikin tarwatsewar kwamfutar hannu da rushewa a cikin jiki.
