Amfani da Hydroxyethyl Cellulose (HEC)

Hadin Hydroxyethyl cellulose (HEC)wani nau'in cellulose ne wanda ba ionic ba wanda aka yi daga cellulose na halitta ta hanyar jerin etherification. Farin foda ne mara ƙamshi, mara ɗanɗano, mara guba, wanda za'a iya narkar da shi a cikin ruwan sanyi don samar da mafita mai haske, kuma ƙimar pH ba ta shafar narkewar. Yana da kauri, ɗaurewa, warwatsewa, emulsifying, ƙirƙirar fim, dakatarwa, shawa, aiki a saman, riƙe danshi da kuma juriya ga gishiri. Ana amfani da shi sosai a fenti, gini, yadi, sinadarai na yau da kullun, takarda, haƙo mai da sauran masana'antu.

Babban fannonin aikace-aikace:

1. Fenti: Fenti mai tushen ruwa ruwa ne mai ƙauri wanda aka ƙera da sinadarai masu narkewa na halitta ko ruwa bisa ga resin, ko mai, ko emulsion, tare da ƙara ƙarin abubuwa masu dacewa. Rufin da aka yi da ruwa tare da kyakkyawan aiki yakamata ya kasance yana da kyakkyawan aikin aiki, ƙarfin ɓoyewa mai kyau, manne mai ƙarfi, da kuma kyakkyawan aikin riƙe ruwa; cellulose ether shine mafi kyawun kayan da aka yi amfani da su don samar da waɗannan kaddarorin.

2. Gine-gine: A fannin masana'antar gini, ana amfani da HEC a matsayin ƙari ga kayan aiki kamar kayan bango, siminti (gami da kwalta), tayal ɗin da aka manna da kayan ƙulla, waɗanda za su iya ƙara danko da kauri na kayan gini, inganta mannewa, mai, da riƙe ruwa. Ƙara ƙarfin lanƙwasa na sassa ko sassan, inganta raguwar ƙaiƙayi, da kuma guje wa fasa gefuna.

3. Yadi: audugar da aka yi wa magani da HEC, zaruruwan roba ko gauraye suna inganta halayensu kamar juriyar abrasion, rini, juriyar wuta da juriyar tabo, da kuma inganta kwanciyar hankali na jikinsu (shrinkage) da karko, musamman ga zaruruwan roba, wanda ke sa su zama masu numfashi kuma yana rage wutar lantarki mai tsauri.

4. Sinadarin yau da kullun: Cellulose ether wani abu ne mai mahimmanci a cikin samfuran sinadarai na yau da kullun. Ba wai kawai yana iya inganta danko na kayan kwalliyar ruwa ko emulsion ba, har ma yana inganta watsawa da kwanciyar hankali na kumfa.

5. Takarda: A fannin yin takarda, ana iya amfani da HEC a matsayin wakili mai girman girma, wakili mai ƙarfafawa da mai gyara takarda.

6. Hako mai: Ana amfani da HEC a matsayin maganin kauri da daidaita shi a tsarin sarrafa mai. Yana da sinadarai masu kyau a fannin mai. An yi amfani da shi sosai a fannin hako mai, kammala rijiyoyi, siminti da sauran ayyukan samar da mai a ƙasashen waje a shekarun 1960.

Sauran fannoni na aikace-aikace:

HECzai iya taka rawar manne guba ga ganyen a ayyukan feshi; Ana iya amfani da HEC a matsayin mai kauri don feshi mai ƙarfi don rage kwararar magunguna, ta haka ne zai ƙara tasirin amfani da feshi mai kauri. Hakanan ana iya amfani da HEC a matsayin wakilin samar da fim a cikin wakilan rufe iri; a matsayin mai ɗaurewa a cikin sake amfani da ganyen taba. Ana iya amfani da Hydroxyethyl cellulose a matsayin ƙari don ƙara aikin rufe kayan hana wuta, kuma an yi amfani da shi sosai a cikin shirye-shiryen "masu kauri masu hana wuta". Hydroxyethyl cellulose na iya inganta ƙarfin danshi da raguwar yashi siminti da tsarin yashi silicate na sodium. Ana iya amfani da Hydroxyethyl cellulose a cikin samar da fina-finai da kuma azaman mai watsawa a cikin samar da zamewar microscopic. Mai kauri a cikin ruwa tare da yawan gishiri da ake amfani da shi a cikin sarrafa fim. Ana amfani da shi azaman mai ɗaurewa da mai wartsakewa mai ƙarfi ga wakilan fluorescent a cikin rufin bututun fluorescent. Yana iya kare colloid daga tasirin yawan electrolyte; hydroxyethyl cellulose na iya haɓaka ajiyar wuri ɗaya a cikin maganin plating cadmium. Ana iya amfani da shi don ƙirƙirar maɗauran ƙarfi don yumbu. Maganin hana ruwa shiga cikin wayoyin da suka lalace.
