HEC (Hydroxyethylcellulose) ni polymer ikunze gukoreshwa mumazi ya elegitoronike hamwe nibisabwa byinshi mubicuruzwa byinganda n’abaguzi, cyane cyane mu myenda, amavuta yo kwisiga, imiti n’ibiribwa. Uburyo bwo kuvomera HEC bivuga inzira ifu ya HEC ikurura amazi igashonga mumazi kugirango ibe igisubizo kimwe.
Ibintu bigira ingaruka kumwanya wa HEC
Igihe cya hydration ya HEC ntabwo cyagenwe, ariko kirebwa nibintu byinshi. Mubisanzwe, igihe cyo gufata amazi ya HEC mumazi gishobora gutandukana muminota mike kugeza kumasaha make. Ibikurikira nimpamvu zingenzi zigira ingaruka kumwanya wa HEC:
Uburemere bwa molekuline n'urwego rwo gusimbuza HEC: Uburemere bwa molekuline n'urwego rwo gusimbuza HEC (urwego rwo gusimbuza bivuga urwego amatsinda ya hydroxyethyl asimbuza amatsinda ya hydroxyl muri molekile ya selile) bizagira ingaruka cyane ku gipimo cy’amazi. HEC ifite uburemere bunini bwa molekile ifata igihe kinini kugirango hydrate, mugihe HEC ifite urwego rwo hejuru rwo gusimbuza ikunda kugira amazi meza kandi umuvuduko wo kwihuta uzihuta.
Ubushyuhe bwamazi: Ubushyuhe bwamazi nimwe mubintu byingenzi bigira ingaruka kumwanya wa HEC. Muri rusange, ubushyuhe bwamazi burashobora kwihutisha inzira ya HEC. Kurugero, mumazi ashyushye, HEC ihindura vuba vuba kuruta mumazi akonje. Nyamara, ubushyuhe bw’amazi buri hejuru cyane bushobora gutuma HEC ishonga mu buryo butaringaniye kandi igatera uduce, bityo rero birasabwa kugenzura ubushyuhe bw’amazi hagati ya 20 ° C na 40 ° C.
Gukurura umuvuduko nuburyo: Gukurura nuburyo bwingenzi bwo kuzamura HEC hydration. Umuvuduko ukabije wihuta, igihe kigufi cya hydration ya HEC mubisanzwe. Ariko, kurenza urugero birashobora kuzana ibibyimba byinshi, bigira ingaruka kumiterere yumuti. Mubisanzwe birasabwa kongeramo ifu ya HEC gahoro gahoro hamwe n'umuvuduko muke kugirango wirinde gukora agglomerate no gukomeza kubyutsa mu buryo bwuzuye mugihe cyamazi.
pH agaciro k'igisubizo: HEC irumva neza agaciro ka pH kandi ikora neza mubutabogamye cyangwa acide nkeya. Mugihe cyimiterere ya pH ikabije (nka acide ikomeye cyangwa base), gukomera kwa HEC birashobora kugira ingaruka, bityo bikongerera igihe cyamazi. Kubwibyo, muri rusange birasabwa gukora hydration ya HEC mubidukikije hafi ya pH.
Uburyo bwo kubanziriza HEC: Uburyo bwo kubanziriza nko gukama, gusya, nibindi bizagira ingaruka no kumikorere ya HEC. Ifu yatunganijwe neza ifu ya HEC irashonga kandi ikayobora vuba. Kurugero, mbere yo gukwirakwiza ifu ya HEC muri Ethanol cyangwa glycerine mbere yo kuyongerera mumazi irashobora kugabanya cyane igihe cyamazi.
Ibibazo Bikunze Kubazwa Mugihe cya HEC Igikorwa
Mugihe cya hydration ya HEC, urashobora guhura nibibazo bimwe bikunze kugaragara, akenshi bifitanye isano nuburyo bukoreshwa cyangwa ibidukikije:
Agglomeration: Mugihe ibintu bidakwiye, ifu ya HEC irashobora gukora agglomerations mumazi. Ubusanzwe biterwa nuko iyo ifu ya HEC ihuye namazi, igipande cyo hanze gihita gikurura amazi kandi kikabyimba, bikabuza urwego rwimbere guhura namazi, bityo bikabyara uduce. Ibi bintu byongerera igihe cyamazi kandi biganisha kumuti inhomogeneity. Kugira ngo wirinde ibi, mubisanzwe birasabwa gusuka buhoro buhoro muri poro ya HEC mugihe ukurura.
Ikibazo cyibibyimba: Munsi yo gukata cyane cyangwa gukurura byihuse, ibisubizo bya HEC bikunda kumenyekanisha umubare munini wibibyimba. Ibibyuka byo mu kirere birashobora kugira ingaruka kumiterere yumuti wanyuma, cyane cyane iyo bikoreshejwe amarangi cyangwa kwisiga. Kubwibyo, gukurura imbaraga bigomba kwirindwa mugihe cyogutanga amazi, kandi kwibibyimba birashobora kugabanuka wongeyeho defoamers.
Guhindura ibisubizo bya viscosity: Ubukonje bwumuti wa HEC bwiyongera buhoro buhoro uko hydration igenda. Mubisabwa bimwe, nko gukora ibifuniko cyangwa ibifatika, kugenzura ibishishwa ni ngombwa. Niba igihe cyo gutanga amazi ari kirekire, viscosity irashobora kuba ndende cyane, bigira ingaruka kumikorere. Kubwibyo, kugenzura neza igihe cyamazi ningirakamaro kugirango ubone igisubizo cyifuzwa.
HEC Hydration mubikorwa bifatika
Mubikorwa bifatika, inzira ya hydration ya HEC mubisanzwe ikenera kunozwa hamwe nibikorwa byihariye byo gukora nibisabwa nibicuruzwa. Kurugero, muburyo bwo kwisiga, kugirango ubone uburyo bwifuzwa kandi butajegajega, HEC ikunze kubanza gushonga mumazi ashyushye hanyuma ibindi bikoresho bikongerwaho buhoro buhoro. Mububiko bwububiko, birashobora kuba nkenerwa guhindura umuvuduko ukabije nubushyuhe bwamazi kugirango byihutishe gahunda ya HEC, bityo bizamura umusaruro.
Igihe cya hydration ya HEC ninzira yingirakamaro kandi igira ingaruka zose kubintu byinshi. Muburyo butandukanye bwo gusaba, bigomba guhindurwa no kunozwa ukurikije ibihe byihariye kugirango HEC ibe ihindagurika vuba kandi iringaniye kandi ikore igisubizo gihamye. Ibi ntabwo bifasha gusa kunoza umusaruro ahubwo binashimangira ubuziranenge nigikorwa cyibicuruzwa byanyuma.
