Hydroxyethyl selulose (HEC) ni polymer idafite ionic, amazi-elegitoronike ikomoka kuri selile. Ikoreshwa cyane mubikorwa bitandukanye byinganda kubera imiterere yihariye, cyane cyane mugutegura ibifatika. Guhagarara neza hamwe nubushobozi bwabo bwo kugumana amazi nibyingenzi mubikorwa byabo, kandi HEC igira uruhare runini mukuzamura izi ngingo.
Imiterere yimiti nibyiza bya Hydroxyethyl Cellulose
HEC ikorwa nigikorwa cya selile hamwe na okiside ya Ethylene, bikavamo ether ya selile hamwe nitsinda rya hydroxyethyl. Ihinduka ryongera imbaraga za selile mu mazi kandi ryongera ubwiza bwaryo. Urwego rwo gusimbuza (DS) hamwe no gusimbuza umubyimba (MS) wamatsinda ya hydroxyethyl kumugongo wa selulose ugena imiterere ya HEC. Mubisanzwe, DS na MS yo hejuru itera kwiyongera kwamazi no kwiyegeranya, bigatuma HEC ikora neza kandi igahinduka.
Uburyo bwo gufatira hamwe
Gufata neza bivuga ubushobozi bwo gufatira hamwe kugumya guhuza, guhuza ibitsina, hamwe nibikorwa biranga igihe. Ibintu byinshi bigira uruhare muguhuza neza, harimo imiterere ya rheologiya, kurwanya gutandukana kwicyiciro, no guhuza nibindi bice.
Imiterere ya Rheologiya
Imiterere ya rheologiya yifata, nkubwiza bwimyitwarire nimyitwarire yo kogosha, nibyingenzi kubikoresha no gukora. HEC itezimbere iyi miterere mugukora imiterere y'urusobekerane muri matrise ifatika. Iminyururu ya polymer ya HEC ikorana hagati yayo hamwe nibice bifata, bigatanga igisubizo kiboneye kirwanya imigezi mugihe gito cyogosha ariko kikaba gike cyane munsi yicyuma kinini. Iyi myitwarire yogosha ni ingirakamaro mugihe cyo gukoresha ibifatika, kuko itanga uburyo bworoshye bwo gukwirakwiza no gukoreshwa mugihe ukomeje gushikama bimaze gukoreshwa.
Kurwanya Gutandukanya Icyiciro
Gutandukanya icyiciro mubice bifata bishobora kubaho bitewe no kudahuza ibice bitandukanye cyangwa bitewe nihinduka ryibidukikije nkubushyuhe nubushuhe. HEC ifasha gukumira gutandukanya ibyiciro ikora nka stabilisateur ya colloidal. Kamere ya hydrophilique ituma ishobora gukorana namazi nibindi bice bigize polar, bigakora imvange imwe. Byongeye kandi, uburemere buke bwa HEC butanga steric stabilisation, bigabanya amahirwe yo gutandukana kwicyiciro mugihe.
Guhuza nibindi bice
HEC irahujwe nurwego runini rwibintu bifata, harimo ibisigara, ibyuzuza, nibindi byongeweho. Uku guhuza kwemeza ko HEC ishobora kwinjizwa muburyo butandukanye bwo gufatira hamwe bitabangamiye imikorere yabo. Byongeye kandi, HEC irashobora kongera ikwirakwizwa ryuzuza hamwe nibindi bice bikomeye muri afashe, bikagira uruhare mubicuruzwa bimwe kandi bihamye.
Ibyiza byo Kubika Amazi
Kubika amazi numutungo wingenzi kubikorwa byinshi bifata, cyane cyane birimo insimburangingo cyangwa igihe kirekire cyo gufungura. HEC yongerera imbaraga ubushobozi bwo gufata amazi yifashishije uburyo bwinshi.
Hydrophilicity hamwe no guhuza amazi
HEC ni hydrophilique cyane, bivuze ko ifitanye isano ikomeye namazi. Uyu mutungo utuma HEC ikurura kandi ikagumana amazi menshi muri matrise ifatika. Amatsinda ya hydroxyethyl kumurongo wumugongo wa selile akora hydrogène ihuza na molekile zamazi, ikabifata neza kandi bikagabanya umuvuduko wamazi. Ibi ni ingenzi cyane mubikorwa aho gukomeza urwego runaka rwubushuhe ningirakamaro kumikorere ya adhesive.
Imiterere ya firime hamwe nimbogamizi
Usibye guhuza amazi, HEC igira uruhare mu gukora firime ikomeza hejuru yifatizo. Iyi firime ikora nkinzitizi yo gutakaza ubushuhe, bikarushaho kongera amazi. Ubushobozi bwo gukora firime ya HEC ni ingirakamaro mubisabwa aho bisabwa igihe kinini cyo gufungura, nko mubifotora hamwe na tile. Mugutinda guhumeka kwamazi, HEC iremeza ko ibifatika bikomeza gukora mugihe kirekire, bikemerera guhinduka no guhinduranya ibikoresho byahujwe.
Ingaruka ku Kuma Igihe n'imbaraga zifatika
Imiterere yo gufata amazi ya HEC nayo igira ingaruka kumyuma n'imbaraga zanyuma zifatika. Mugumana amazi muri matrike yometse, HEC igenzura igipimo cyo gutakaza amazi, biganisha kumyanda igenzurwa kandi imwe. Ukumisha kugenzurwa ningirakamaro kugirango ugere ku mbaraga zifatika zifatika, kuko zituma habaho firime nziza kandi igahuza na substrate. Kuma vuba birashobora kuvamo imigozi idakomeye hamwe no kudafatana nabi, mugihe uburyo bwo gukama bugenzurwa bworoherezwa na HEC butuma ingingo zikomeye kandi ziramba zifatika.
Porogaramu ya HEC muri Adhesives
HEC ikoreshwa muburyo butandukanye bwo gufatira hamwe, harimo:
Ibikoresho byubaka: HEC isanzwe ikoreshwa mubikoresho byubaka kugirango igumane amazi kandi yibyibushye, itume imiyoboro ihamye kandi iramba mubikoresho byubaka.
Igicapo cya Wallpaper: Ubushobozi bwa HEC bwo kugumana amazi no gutanga igihe kinini cyo gufungura bituma biba byiza kumpapuro zifatika, bikemerera gukoreshwa no guhinduka.
Amatafari ya Tile: Mubifata byamafiriti, HEC yongerera imbaraga akazi hamwe no gufatana mugukomeza ibirimo ubuhehere bukenewe mugushiraho neza no guhuza.
Ibikoresho byo gupakira: HEC itezimbere imikorere yama paki yongerera imbaraga hamwe no kurwanya itandukanyirizo ryicyiciro, itanga ubuziranenge nibikorwa.
Hydroxyethyl selulose igira uruhare runini mukuzamura ituze hamwe no gufata amazi yibikoresho. Imiterere yihariye yimiti nimiterere bigira uruhare mugutezimbere imiterere ya rheologiya, kurwanya gutandukana kwicyiciro, no guhuza nibintu bitandukanye bifata. Byongeye kandi, hydrophilicity hamwe nubushobozi bwo gukora firime ya HEC byongera cyane gufata amazi, biganisha ku kugenzura neza ibihe byumye n'imbaraga zifatika. Guhindura no gukora neza kwa HEC bituma iba ikintu ntagereranywa mugutegura ibintu byinshi bifatika, byemeza imikorere yabo no kwizerwa mubikorwa bitandukanye.
