Ibikorwa byumusaruro nibikorwa bya HydroxyEthyll Cellulose (HEC)

I. IRIBURIRO

HydroxyAythyl Cellulose (HEC) ni polymer itari ipomeke y'amazi akoreshwa cyane mu gukuramo peteroli, amarangi, imiti, imiti ya buri munsi, impapuro n'indi mirima. HEC iboneka kubitekerezo bya selile, kandi imitungo yacyo hamwe nuburyo bwo gukoresha byagenwe cyane na Hydroxyyerthyl abasimbuye hydroxyyerthy kuri molekile ya selile.

II. Igikorwa

Inzira yumusaruro wa Hec ahanini ni intambwe zikurikira: Guhangana na selile, gukaraba, kubura umwuma, gukama no gusya. Ibikurikira ni intangiriro irambuye kuri buri ntambwe:

Guhangana na selile

Cellulose avurwa bwa mbere na alkali kugirango akore selile ya alkali (selile alkali). Iyi nzira isanzwe ikorwa muri reaction, ukoresheje sodium hydroxide yo kuvura selile kamere kugirango ikore selile ya alkali. Imyitwarire yimiti ni izi zikurikira:

Selire-yewe + naoh → selile-o-na + h2ocell-yewe + naoh → selile-o-na + h 2o

Noneho, selile ya alkali yitwaye neza kuri etylene oxide kugirango ikore hydroxyyethyl selile. Imyitwarire ikorwa mu muvuduko mwinshi, ubusanzwe 30-100 ° C, hamwe na reaction yihariye ni izi zikurikira:

Selile-o-na + ch2ch2o → selile-o-ch2ch2Ohhcell-o-na + ch 2Co 2o → selile-oh

Iyi reaction isaba kugenzura neza ubushyuhe, igitutu nubwinshi bwa Ethylene oxide yongeyeho kugirango tumenye neza kandi ubwiza bwibicuruzwa.

Gukaraba

Ibisubizo bya Rec ubusanzwe bikubiyemo alkali bidasubirwaho, Ethylene okiside nibindi bicuruzwa, bigomba gukurwaho no gukaraba amazi cyangwa imbinya mmema. Umubare munini w'amazi usabwa mugihe cyo gukaraba amazi, hamwe namazi yamazi nyuma yo gukaraba agomba gufatwa no gusohoka.

Umwuma

HEC itose nyuma yo gukaraba igomba guhabwa umwuma, mubisanzwe na vacuum ifura cyangwa gutandukana kwa Centrifugal kugirango ugabanye ubushuhe.

Kuma

Umuhetsi wumuntu wumye, mubisanzwe mugukama cyangwa gucana. Ubushyuhe nigihe kigomba kugenzurwa cyane mugihe cyumye kugirango wirinde gutesha agaciro ubushyuhe bwo hejuru cyangwa agglomera.

Gusya

Uburoma bwa HEC bugomba kuba butaka kandi bukonjaje kugirango ugere ku kugabura ibice kimwe, kandi amaherezo bigize ifu cyangwa ibicuruzwa bya granular.

III. Ibiranga imikorere

Amazi

Hec ifite amazi meza kandi arashobora gushonga vuba haba mumazi akonje namazi ashyushye kugirango akore ikintu gito cyangwa cyoroshye. Iyi mitungo yo kwishyurwa ituma yakoreshejwe cyane nkuwabyimbye kandi ikingamiro mubirori nibicuruzwa bya buri munsi.

Kubyimba

HEC yerekana ingaruka zikomeye mubisubizo bitangaje, kandi ubushyuhe bwayo bwiyongera hamwe no kwiyongera k'uburemere bwa molekile. Uyu mutungo wijimye ushoboza uruhare mubyimbye, kugumana amazi no kunoza imikorere yubwubatsi mumavuta ashingiye kumazi no kubaka minisiteri.

Rheologiya

HEC igisubizo cyibitangaje gifite imiterere yihariye yamarangamutima, hamwe nibyishimo byayo bihinduka hamwe nimpinduka yimiterere yimyenda, yerekana kogosha cyangwa pseudoplastit. Iyi mitungo yuburyo ituma ihindura amazi n'imikorere yubwubatsi mu bice hamwe n'amazi yo gucukura peteroli.

Kuzenguruka no guhagarikwa

HEC ifite imiterere myiza kandi ihagarikwa imiterere, ishobora gutuza uduce cyangwa ibitonyanga muri sisitemu yo gutatanya kugirango birinde gushishikarira no kwikuramo. Kubwibyo, wec akunze gukoreshwa mubicuruzwa nko kure ya emulsion no guhagarikwa ibiyobyabwenge.

Biodegradable

HEC ni ko selile isanzwe ikomoka kuri biodegrafiya nziza, nta gutinda kubidukikije, kandi yujuje ibisabwa byicyatsi kibisi.

IV. Ibisabwa

IHURIRO

Mu mavuta ashingiye ku mazi, HEC ikoreshwa nk'igituba no mu kigero cyo kunoza amazi, imikorere yo kubaka no kugabanya imitungo yo kugata.

Kubaka

Mu bikoresho byo kubaka, HEC ikoreshwa mu miterere ya sima ishingiye kuri sima na Prowder ifu mu kuzamura imikorere yo kubaka no kugumana amazi.

Imiti ya buri munsi

Mu kwihabisha, shampoos, hamwe na yometseho amenyo, hec ikoreshwa nkuwabyimbye kandi stilizer kugirango ateze imbere ibyiyumvo no gutuza ibicuruzwa. 

Amavuta

Muri peteroli ishimangira amazi ya peteroli, avunika, HEC ikoreshwa muguhindura imiterere yuburyo no guhagarika imitungo yo gucukura no kunoza imikorere no kunoza umutekano.

Impapuro

Mubyitegererezo, HEC ikoreshwa mu kugenzura amazi ya Pulp kandi itezimbere uburinganire nubutaka bwimpapuro.

HydroxyAythyl Cellulose (HEC) yakoreshejwe cyane mu mirima myinshi y'inganda bitewe n'amazi meza, kubyimba, imitungo yegeranye, ndetse na biodegransion. Inzira yacyo irakuze. Binyuze mu ntambwe zo gukora selile, gukaraba, kubura umwuma, gukama no gusya, ibicuruzwa bya hec bifite imikorere ihamye kandi bifite ireme birashobora gutegurwa. Mu bihe biri imbere, hamwe no kunoza ibisabwa kurinda ibidukikije no guteza imbere ikoranabuhanga, ibyifuzo bya ECC bizagukwirakwiza.
