Ni hydroxyyerlcellylcellse

Hydroxyyerlcellylcellse (hec) ni polymer itari ionic, polymer ifata amazi akomoka kuri selile. Bikunze gukoreshwa mu nganda zinyuranye nka farucetique, kwisiga, ibiryo, n'ibicuruzwa byita ku giti cyabo kubera kubyimba, gutuza, no gutunganya ibintu.

Imiterere yimiti ya hydroxyEthylceellylcellse

HEC ni polymer yahinduwe mubugari bwahinduwe, aho hydroxyeryethyl yamenyeshejwe kuri selile. Iyi mico yongera amazi yoroheje nibindi bintu bya selile. Amatsinda ya hydroxyyeryls (-ch2ch2oh) yahujwe na hydroxyl (-Oh) amatsinda ya molekile ya selile. Iyi mpinduka ihindura imitungo yumubiri na shimi ya selile, bigatuma bikwiranye nuburyo butandukanye.

Akabintu

1. Kugabanuka

Ubugari bwa selile ni ibintu byaka kuberako birimo amatsinda ya hydroxyl, ashobora gukomera. Ariko, intangiriro yamatsinda ya hydroxyyeryl kuri selile ya selile ihindura ibiranga amakosa yayo. Kubaho kw'amatsinda ya hydroxyeryethyl irashobora kugira ingaruka kumasezerano yo gutandukana ya HEC ugereranije na selile ituje.

2. Kwipimisha

Kwipimisha byaka ni ngombwa kugirango umenye ingaruka zumuriro zijyanye nibikoresho. Ibizamini bitandukanye byagereranijwe, nka ASTM E84 (uburyo busanzwe bwo kwipimisha kugirango buranga ibikoresho byubaka) na UL 94 (Igipimo cyumutekano wibikoresho nibikoresho), bikoreshwa mugusuzuma gusa ibikoresho. Ibi bizamini bisuzuma ibipimo nkikirimi bikwirakwira, iterambere ryumwotsi, no gutwika.

Ibintu bireba

1. Ibirimo

Kuba ahantu heza birashobora guhindura ibikoresho byaka. Ibikoresho bya Cellulopique bikunda gucika intege mugihe birimo urwego rwo hejuru rwinshi kubera kwinjiza ubushyuhe no gukonjesha amazi. Hydroxyyerlcellylcellse, kuba ufite amazi, birashobora kubamo ubushuhe butandukanye bitewe nibidukikije.

2. Ingano yubunini nubucucike

Ingano yubunini nubucucike bwibikoresho birashobora kugira ingaruka kubusa. Ibikoresho bigabanijwe neza muri rusange bifite ahantu hirengeye, biteza imbere gutwikwa byihuse. Nyamara, hec isanzwe ikoreshwa muburyo bwifu cyangwa ikwirakwizwa hamwe nubunini bugenzurwa kugirango bubahiriza ibisabwa.

3. Kubaho inyongeramusaruro

Mubikorwa bifatika, hydroxyyerlceselcese fortions irashobora kuba irimo ingingo nka plastizi, stabilizers, cyangwa abategetsi ba Flame. Izi nguzanyo zirashobora guhindura ibintu byaka byaka ibicuruzwa bishingiye kuri hec. Kurugero, ibiti bya flame birashobora guhagarika cyangwa gutinza gutwika no gukwirakwiza umuriro.

Amazi meza n'umutekano

1. Kubika no gufata

Ububiko bukwiye no gutunganya ni ngombwa kugirango ugabanye ibyago byo guhanga umuriro. Hydroxyyerlceellylcellse igomba kubikwa mu gace k imyuka, ihumeka neza kure y'amasoko yo gutwika. Hagomba gufatwa kugirango wirinde guhura n'ubushyuhe bukabije cyangwa urumuri rw'izuba, rushobora gutuma kwangirika cyangwa gutwikwa.

2. Kumenyekanisha

Abakora n'abakoresha ibicuruzwa bya hydroxyrathlceellceylcellslcellslcellsellsellus bagomba kubahiriza amategeko n'umutekano abigenga. Imibiri ishinzwe kugenzura umutekano n'ubuyobozi bw'ubuzima (OSHA) muri Amerika n'ibigo by'Uburayi byo mu Burayi (ECHA) mu muryango w'uburayi bitanga umurongo ngenderwaho wo gutunganya neza no gukoresha imiti.

3. Ingamba zo guhagarika umuriro

Mugihe umuriro urimo hydroxyyerlceethylceellse cyangwa ibicuruzwa birimo ibigo bya HEC, ingamba zikwiye zo guhagarika umuriro zigomba gushyirwa mu bikorwa. Ibi birashobora kubamo gukoresha amazi, dioxyde de carbone, kuzimya imiti yumye, cyangwa ifuro, bitewe n'imiterere yumuriro nibidukikije.

Hydroxyyerlcellylcellse ni polymer yahinduwe yahinduwe ikoreshwa mu nganda zinyuranye zo kubyimba no guhungabanya umutekano. Mugihe selile nziza yaka, intangiriro yamatsinda ya hydroxyyeryl ahindura ikintu cyaka umuriro. Ibintu nkibintu byubushuhe, ingano yinshi, ubucucike, kandi kubashyingiranywe birashobora guhindura uko byaka umuriro bya hydroxyyerlceellslceylceellslceylceellsellylceylceylceellslceylceells. Ububiko bukwiye, gutunganya, no gukurikiza amabwiriza y'umutekano ni ngombwa mu kugabanya ingaruka z'umuriro zijyanye na HEC. Ubundi bushakashatsi no kwipimisha birashobora gukenerwa kugirango dusobanukirwe neza imyitwarire ya Hydrogisiethylceethlceemylceellslcellse mubihe bitandukanye.
