Hadin Hydroxyethyl cellulose (HEC)polymer ne mai narkewar ruwa wanda ba ionic ba. Ana amfani da shi sosai a masana'antar shafa saboda kyawun narkewar ruwa, kauri, halayen samar da fim da kuma kyakkyawan aikin saman. A cikin tsarin shafa, HEC ba wai kawai yana ba da kyawawan halayen rheological ba, har ma yana taka muhimmiyar rawa wajen mannewa na shafa.
1. Halayen tsarin HEC
Kwayoyin HEC sun ƙunshi sarƙoƙin cellulose da kuma abubuwan da ke cikin hydroxyethyl. Sarƙoƙin cellulose ɗinsa yana da tsarin polyhydroxy, wanda zai iya samar da hulɗa mai ƙarfi da saman abin da ke cikin murfin ta hanyar haɗin hydrogen, ta haka yana inganta mannewar murfin. Bugu da ƙari, abin da ke cikin hydroxyethyl a cikin ƙwayar AnxinCel®HEC yana ƙara narkewar ruwa, yana ba shi damar warwatsewa daidai a cikin murfin, ta haka yana inganta ingancin samar da fim na murfin.
2. Tsarin HEC akan Mannewa na Rufi
HEC a cikin shafa yana ƙara mannewar shafa ta hanyar waɗannan hanyoyin:
Ingantaccen danshi a saman
HEC yana da kyakkyawan aikin saman, wanda zai iya rage matsin lamba na saman murfin da kuma inganta danshi na murfin zuwa saman substrate. Wannan danshi yana bawa murfin damar tuntuɓar saman substrate sosai, yana rage gibin da ke tsakanin murfin, ta haka yana inganta mannewa tsakanin murfin da substrate.
Haɗin hydrogen yana ƙara haɗin fuska
Rukunin hydroxyl a cikin ƙwayoyin HEC na iya samar da haɗin hydrogen tare da ƙungiyoyin aiki na polar akan saman substrate (kamar itace, gilashi, ƙarfe, da sauransu). Wannan tasirin yana haɓaka haɗin jiki tsakanin murfin da substrate, yana sa murfin ya zama ƙasa da barewa a ƙarƙashin ƙarfin waje.
Tsarin mallakar rheological
HEC yana da tasiri mai mahimmanci akan halayen rheological na murfin, yana rage ruwansa ta hanyar kauri murfin da kuma hana yawan lanƙwasa murfin akan saman substrate. Wannan siffa tana taimakawa murfin ya samar da fim iri ɗaya akan saman substrate kuma yana rage raguwar mannewa da ke faruwa sakamakon rashin daidaiton kauri na fim.
Tasirin taimakon samar da fim
HEC na iya inganta ingancin samar da fim na murfin yayin aikin samar da fim, yana tabbatar da cewa murfin yana da ci gaba da daidaito bayan bushewa. Wannan daidaiton yana rage guraben da ke da lahani na murfin, ta haka yana inganta mannewa gaba ɗaya.
3. Misalan aikace-aikacen HEC a cikin nau'ikan rufi daban-daban
Rufin gine-gine na ruwa
A fannin gyaran rufin gine-gine, HEC yana inganta mannewar rufin da aka yi da bangon bango (kamar siminti ko gypsum) ta hanyar kauri, inganta danshi, da kuma ƙara ƙarfin fim. Bugu da ƙari, halayen HEC na hana lanƙwasawa suna taimakawa wajen santsi a saman rufin bayan an shafa su.
Rufin katako
Ga rufin katako, tasirin haɗin hydrogen na HEC ya bayyana musamman. Saman katako yana da wadataccen rukunin hydroxyl, kuma HEC na iya ƙulla alaƙa mai ƙarfi da shi, wanda hakan ke inganta dorewa da mannewar murfin sosai.
Rufin ƙarfe
A cikin shafan ƙarfe, inganta danshi na HEC yana ba da damar shafan ya rufe saman ƙarfe mafi kyau kuma yana haɓaka mannewar murfin ta hanyar polarity. Wannan yana da mahimmanci musamman a cikin shafan hana tsatsa.
Rufin gilashi
HEC yana da kyakkyawan tasirin mannewa akan saman da ba su da santsi kamar gilashi, kuma halayen polar na ƙungiyoyin hydroxyl a cikin ƙwayoyin sa na iya rama rashin daidaiton sinadarai tsakanin saman gilashin da murfin.
4. Iyakokin HEC akan mannewa na shafi
Duk da cewaHECyana da fa'idodi masu yawa wajen inganta mannewa na shafi, yana kuma da wasu ƙuntatawa. Misali, HEC yana da sauƙin sha danshi a cikin yanayi mai zafi, wanda zai iya haifar da raguwar aikin shafa. Bugu da ƙari, ga wasu shafan masana'antu masu yawan buƙata, HEC yana buƙatar amfani da shi tare da wasu ƙari don cimma babban aiki.
A matsayin wani muhimmin abin ƙara kauri da kuma samar da fim, amfani da AnxinCel®HEC a cikin shafi yana inganta mannewar shafi sosai. Yana ba da damar shafa shafi ya dace da nau'ikan abubuwa daban-daban ta hanyoyi daban-daban kamar haɓaka danshi, samar da haɗin hydrogen, da inganta halayen samar da fim. Duk da haka, a ainihin aikace-aikacen, ya kamata a inganta adadin ƙari da dacewa da HEC tare da takamaiman dabarar shafa da yanayin amfani don ba da cikakken wasa ga rawar da yake takawa.
