Sellululose na Slal -Lulose (HEC) Polymer ne mai narkewa wanda ba ionic da aka ruwa sosai a hakar mai ba, mayafin, gini, sunadarai yau da kullun da sauran filayen. An samo HEC ta hanyar satar sinadarai, da kadarorinta da amfani galibi sun ƙaddara su ta hanyar kwayoyin halittar sinadarai a kan kwayoyin selulose.
II. Tsarin samarwa
Tsarin samarwa na HEC yakan hada da matakai masu zuwa: Wanke, Em theherigation, bushewa da bushewa. Mai zuwa cikakken bayani ne ga kowane mataki:
Cellulose Erthado
An fara bi da cellulose tare da alkali don samar da alkali celulose (Preal alkali). Wannan tsari yawanci ana aiwatar dashi a cikin mai martaba, ta amfani da maganin sodium hydroxide don magance sel na halitta don samar da sel na zahiri. Hankalin sunadarai shine kamar haka:
Preal-Oh + Naho → Sel-O-Na + H2ocelll
Bayan haka, Alkalilluloose ya dogara da ethylene oxide don samar da sel slallulose. A dauki ne da za'ayi karkashin matsin lamba, yawanci 30-100 ° C, da takamaiman amsawar shine kamar haka:
Cell-Ch2ch2o → Cell-O-Ch2ch2onl-O-Na + Ch 2ch 2o → Cell-O-Ch 2ch 2oh
Wannan bayanin yana buƙatar madaidaicin iko na zazzabi, matsi da adadin ethylene oxide da yawa don tabbatar da daidaituwa da ingancin samfurin.
Wanka
A sakamakon haddi ya ƙunshi alkali na ethylene da kuma wasu daga-samfuran, waɗanda suke buƙatar cire su da wanking na ruwa ko warkewar kwayar cuta. Ana buƙatar babban adadin ruwa yayin aiwatar da ruwan sha, da kuma sharar gida bayan wankewar buƙatar a bi da kuma a cire shi.
Rashin ruwa
Rigar da rigar da aka bushe bayan an bushe, yawanci ta hanyar iska ko rabuwa da centrifugal don rage abun cikin danshi.
Bushewa
A dhydrated hec ya bushe, yawanci da bushewa ko bushewa flash. Za'a iya sarrafa zafin jiki da lokaci mai tsananin sarrafawa yayin aiwatar da bushewa don guje wa babban yanayin zafin jiki ko agglomeration.
Tuadn ruwa
Tufafin da aka bushe yana buƙatar zama ƙasa da sieve don cimma daidaitaccen rabon size, kuma a ƙarshe samar da foda ko samfurin grancular.
III. Halaye na aiki
Sanarwar ruwa
HEC yana da kyakkyawan abinci mai kyau kuma zai iya narke cikin sauri a cikin ruwan sanyi da ruwan zafi don samar da mafita mai sauƙi ko transluction bayani. Wannan kadarorin da ake amfani da shi yana sa ya yi amfani da shi sosai azaman tsawa da kuma tsayayye a coftings da samfuran sunadarai na yau da kullun.
Tsayawa
HEC yana nuna ingantaccen tasirin thickening a cikin mafita mai ruwa, kuma danko yana ƙaruwa tare da karuwar nauyin kwayoyin. Wannan dukiyar mai kauri tana ba ta taka rawa a cikin thickening, riƙewar ruwa da inganta aikin gini a cikin sanyaya ruwa da gina masu ruwa.
Na rheorn
Magani mai ruwa mai ruwa-ruwa yana da kaddarorin ƙwararrun abubuwa, kuma tasirin sa yana canzawa tare da canjin karfi na ƙimar kai, yana nuna zubar thinning ko rikice-rikice. Wannan kayan aikin ilimin halittar yana ba shi damar daidaita hasken ruwa da kayan aikin gini a Colleings da ruwa ruwa.
Emulsification da dakatarwa
Hec yana da kyau emulsification da abubuwan da aka dakatar ko da za su iya doguwar rigakafin da aka dakatar ko droplets a cikin tsarin watsawa don hana suttura. Sabili da haka, ana amfani da HEC a cikin samfurori kamar su emulsion coxering da dakatarwar miyagun ƙwayoyi.
Iri-harbani
HEL shine ainihin ƙwayar ƙwayar halitta ta halitta tare da kyawawan halittu, babu gurbataccen yanayin zuwa ga muhalli, kuma yana haɗuwa da buƙatun kare muhalli.
IV. Filayen aikace-aikacen
Mayafa
A cikin sutturar halitta ruwa, ana amfani da HEC azaman baƙin ciki da kuma tsayayye don haɓaka ruwa mai ruwa, aikin gini da kuma abubuwan haɗin gwiwa da kuma sagging kaddarorin mayuka.
Shiri
A cikin kayan gini, ana amfani da HEC a turmi da ke tattare da ciminti don inganta aikin aikin gini da kuma riƙe ruwa.
Magunguna na yau da kullun
A cikin shagunan wanka, shamfo, da haƙoran haƙora, ana amfani da HEC azaman farin ciki da kuma tsayayye don inganta ji da kwanciyar hankali na samfurin.
Katako
A cikin hirar ozonder da ruwaye, Hec ana amfani dashi don daidaita rheorning da rhenan tsinkayen ruwa da inganta kayan hako da aminci.
M
A cikin tsarin takarda, ana amfani da HEC don sarrafa jana mai ruwa mai ruwa da kuma inganta daidaituwa da kaddarorin takarda.
An yi amfani da sel na sel (HEC) a cikin filayen masana'antu da yawa saboda kyakkyawan solility na ruwa, emulsiantinning da kyawawan kaddarorin. Tsarin samarwa yana da girma sosai. Ta hanyar matakan Elloulofication Eltherfiction, wanka, giya, bushewa da niƙa, samfuran HEC tare da ingantaccen aiki da inganci za a iya shirya. A nan gaba, tare da haɓaka buƙatun kariyar muhalli da ci gaban fasaha, yanayin aikace-aikacen HEC zai zama mai yawa.
