Quaternized hydroxyethyl cellulose

Quaternized hydroxyethyl cellulose (QHEC) wani gyare-gyare ne na hydroxyethyl cellulose (HEC) wanda aka mayar da martani tare da fili na ammonium quaternary. Wannan gyare-gyare yana canza kaddarorin HEC kuma yana haifar da polymer cationic wanda ke da nau'ikan aikace-aikace masu yawa, ciki har da samfuran kulawa na sirri, yadi, da suturar takarda.

Ƙaddamarwa na HEC ya haɗa da ƙarawa na ammonium quaternary zuwa kwayoyin HEC, wanda ya gabatar da caji mai kyau a cikin polymer. Mafi yawan amfani da fili na ammonium quaternary don wannan dalili shine 3-chloro-2-hydroxypropyl trimethylammonium chloride (CHPTAC). Wannan fili yana amsawa tare da ƙungiyoyin hydroxyl akan kwayoyin HEC, wanda ya haifar da ingantaccen ƙwayar QHEC.

Ɗaya daga cikin aikace-aikacen farko na HEC yana cikin samfuran kulawa na sirri, irin su shamfu, kayan kwalliya, da kayan gyaran gashi. HEC yana ba da kyakkyawan yanayin kwantar da hankali da kaddarorin kaddarorin gashi, yana sauƙaƙa tsefe da salo. Hakanan ana amfani da HEC azaman mai kauri da rheology modifier a cikin waɗannan samfuran, yana ba da rubutu mai daɗi da haɓaka aikin gabaɗaya.

A cikin aikace-aikacen yadudduka, ana amfani da HEC azaman wakili mai ƙima don auduga da sauran filaye na halitta. HEC na iya inganta ƙima da juriya na abrasion na yadudduka, yana sa su zama masu ɗorewa da sauƙin ɗauka yayin aikin masana'antu. HEC kuma na iya inganta mannewa na dyes da sauran kayan aikin gamawa zuwa masana'anta, yana haifar da launuka masu haske da saurin wankewa.

Hakanan ana amfani da HEC a cikin suturar takarda don haɓaka juriya na ruwa da bugu na takarda. HEC na iya inganta mannewar shafi da rage shigar ruwa da tawada a cikin filayen takarda, wanda ke haifar da fiffike da fitattun kwafi. HEC kuma na iya samar da kyakkyawan santsi da sheki zuwa takarda, haɓaka bayyanarsa da kaddarorin tactile.

Ɗaya daga cikin mahimman fa'idodin HEC shine yanayin cationic, wanda ya sa ya yi tasiri sosai a cikin abubuwan da suka ƙunshi surfactants anionic. Ana amfani da surfactants na Anionic a cikin samfuran kulawa na sirri, amma suna iya yin hulɗa tare da masu kauri marasa ionic, kamar HEC, kuma suna rage tasirin su. HEC, kasancewa cationic, zai iya samar da hulɗar lantarki mai ƙarfi tare da anionic surfactants, yana haifar da ingantacciyar kauri da kwanciyar hankali.

Wani fa'idar HEC ita ce dacewa da sauran nau'ikan nau'ikan nau'ikan nau'ikan. Ana iya amfani da HEC tare da sauran nau'ikan cationic, anionic, da waɗanda ba na ionic ba tare da tasirin aikin sa ba. Wannan ya sa ya zama nau'i mai mahimmanci wanda za'a iya amfani dashi a cikin nau'i-nau'i da aikace-aikace.

HEC yana samuwa a cikin nau'o'i daban-daban da danko, dangane da takamaiman aikace-aikacen da buƙatun ƙira. Yawanci ana ba da shi azaman foda wanda za'a iya tarwatsa shi cikin sauƙi cikin ruwa ko wasu abubuwan kaushi. Hakanan za'a iya ba da QHEC azaman samfurin da aka riga aka rigaya ko kuma ba da kansa ba, wanda ke kawar da buƙatar ƙarin matakan tsaka tsaki yayin tsarin ƙira.

A taƙaice, quaternized hydroxyethyl cellulose wani gyare-gyaren sigar hydroxyethyl cellulose ne wanda aka yi da wani fili na ammonium quaternary. HEC polymer cationic ne wanda ke da nau'ikan aikace-aikace, ciki har da samfuran kulawa na sirri, yadi, da suturar takarda. HEC yana ba da kyakkyawan yanayin kwantar da hankali da kaddarorin kauri, yana haɓaka aikin anionic surfactants, kuma yana dacewa da sauran nau'ikan abubuwan sinadarai. Ƙarfafawa da aikin HEC sun sa ya zama wani abu mai mahimmanci a cikin nau'i-nau'i da aikace-aikace.
