HydroxyAythyl Cellulose (HEC) ni polymer yoroshye amazi akoreshwa cyane mu gucukura amavuta, kubaka, amababi, imyenda, amababi, kwisiga n'izindi nganda. Inzira yacyo ikubiyemo uburyo bworoshye bwa chimique no kugenzura neza.
(1) Gutegura Ibikoresho
Ibikoresho nyamukuru bya hydroxyAythyl selile birimo:
Cellulose: Mubisanzwe cotton itunganijwe-selile cyangwa igiti cya selile irakoreshwa, ikorwa neza kugirango ikureho umwanda.
Ethylene Oxide: Numukozi wingenzi ukora cyane kugirango utangire hydroxyerthyy.
Igisubizo cya Alkali: Mubisanzwe sodium hydroxide igisubizo, gikoreshwa muguhaguru kwa selile.
Solvent Organic: Beopropanol, ikoreshwa mu gusenya selile no guteza imbere reaction.
(2) Intambwe
Alkalisation ya selile:
Guhagarika selile muri social organic (nka isopropanol) hanyuma wongere sodium hydroxide igisubizo cyo alkalisation.
Mu myitwarire ya alkalisation, imiterere ya hydrogen ya selile iracika, ituma amatsinda ya hydroxyl kuri molekile ya moleki byoroshye kubyitwaramo byoroshye na royolene okiside.
Igitekerezo cya alkalisation mubisanzwe gikorwa ku bushyuhe runaka (nka 50-70 ° C) kandi gikomeza mugihe cyigihe kimaze kubyutsa.
Igisubizo cya Guhuza:
Entylene oxide yongewe buhoro buhoro kuri sisitemu ya selile.
Ethylene oxide yitabira amatsinda ya hydroxyl kuri selile kugirango agire hydroxyyethyl selile.
Ubushyuhe bwimyitwarire busanzwe buri hagati ya 50-100 ° C, kandi igihe cyimyitwarire kiratandukanye bitewe nibicuruzwa.
Kuri iki cyiciro, imiterere yimyitwarire (nkubushyuhe, igihe, umubare wa Rothylene oxide, nibindi) kumenya urwego rwo gusimbuza no gukemurwa kwa hydroxyyethyl selile.
Kutabogama no gukaraba:
Nyuma yimyitwarire irangiye, aside (nko muri acide ya hydrochloric) yongeweho yo kutagira igisubizo kirenze, kandi ibicuruzwa byogejwe kugirango ukureho imiti idakekwa nibicuruzwa.
Ubusanzwe gukaraba bikorwa no gukaraba amazi, kandi nyuma yo gukaraba byinshi, agaciro ka PH kabicuruzwa wegereye kutagira aho kutabogama.
Kuzunika no gukama:
HydroxyEthyyl selile iranyuzwa muyungurura kugirango ikureho amazi arenze.
Ibicuruzwa byungurujwe byumye, mubisanzwe ukoresheje umwuka wumye cyangwa ushushe, kugirango ugabanye ibintu byayo muburyo bwerekanwe (nko munsi ya 5%).
Ibicuruzwa byumye biri mubutaka cyangwa ifishi nziza ya granule.
Kumenagura no gusuzuma:
HydroxyEthyyl selile irajanjagurwa kugirango igere ku bunini busabwa.
Ibicuruzwa byajanjaguwe byerekanwe kugirango ubone ibicuruzwa byubunini butandukanye kugirango ubone ibikenewe mubipimo bitandukanye.
Gupakira no kubika:
Ibicuruzwa bya hydroxyyedthyl ibicuruzwa bipakiwe hakurikijwe ibisobanuro.
Ibikoresho byo gupakira mubisanzwe ni umufuka numukungugu umufuka wumukungugu cyangwa igikapu cyimpapuro, wongeyeho umufuka waboshye cyangwa ikarito.
Ububiko mu bubiko bukonje, bwumutse, bufite umwuka mwinshi kugirango wirinde ubushuhe cyangwa kwangirika ubushyuhe.
(3) Igenzura ryiza
Igenzura ryiza ningirakamaro mubikorwa bya hydroxyyethyl selile. Harimo ahanini nibice bikurikira:
Igenzura ryiza ryibikoresho: Menya neza ko ubuziranenge nubwiza bwa selile, Ethylene okiside nibindi bikoresho byabapuye byujuje ibisabwa.
Igenzura ry'umusaruro Ibipimo: Kugenzura neza ibipimo byingenzi nkubushyuhe, igitutu, igihe, agaciro, nibindi kugirango bikemure ibicuruzwa bihamye.
Kwipimisha ibicuruzwa byarangiye: Gerageza rwose impamyabumenyi, viscosity, gukurura, kweza nibindi bipimo byanyuma kugirango bihuze ibisabwa nabakiriya.
(4) kurengera ibidukikije n'umutekano
Umusaruro wa HydroxyAythyl selile urimo imiti nk'imico yawe na englene oxide. Ingamba zo kurengera ibidukikije n'umutekano zigomba gufatanwa mu gihe cyo gukora:
Gutunganya imyanda: Amazi yatangwa mugihe cyimikorere yo kubyara agomba kuvurwa mbere yo gusohoka kugirango wirinde umwanda wibidukikije.
Gutunga imyanda: Ethylene oxide ni uburozi kandi bwaka. Gazi yumurizo umurizo igomba kuvurwa nibikoresho nkibishishwa byinjira kugirango bigabanye umwuka.
Kurinda umutekano: abakoresha bakeneye kwambara ibikoresho birinda kugirango birinde guhura nimiti yangiza. Muri icyo gihe, ibigo bitanga umusaruro bigomba kuba bifite ibikoresho byo gukumira umuriro, gukumira ibitero n'ibindi bikoresho by'umutekano.
Inzira yumusaruro wa HydroxyAythyl selile ikubiyemo imiti myinshi yuzuye imiti no kugenzura ibintu bidafite ishingiro. Kuva mu myiteguro y'ibintu birangirika ku gupakira ibicuruzwa, buri huriro rifite ingaruka zingenzi kumikorere nubwiza bwibicuruzwa byanyuma. Hamwe no gutera imbere ikoranabuhanga no kunoza ibisabwa byo kurengera ibidukikije, gahunda yo gutanga umusaruro wa HydroxyAythyl selile kandi ikomeje kuba ingirakamaro mu kuzamura ireme ry'ibicuruzwa, kugabanya amafaranga no kugabanya ingaruka z'ibidukikije.
