Hejuru no Hasi ya Hydroxyethyl Cellulose

Mu rwego rwo kubyara no gukoresha Hydroxyethyl Cellulose (HEC), ijambo "upstream" na "downstream" ryerekeza ku byiciro bitandukanye murwego rwo gutanga no guha agaciro agaciro. Dore uko aya magambo akoreshwa kuri HEC:

Hejuru:

1. Isoko ry'ibikoresho bito: Ibi bikubiyemo kugura ibikoresho fatizo bisabwa kugirango umusaruro wa HEC. Cellulose, ibikoresho byibanze byibanze mu musaruro wa HEC, mubisanzwe bikomoka ahantu hatandukanye nkibiti byimbuto, ibiti by'ipamba, cyangwa ibindi bikoresho bya fibrous.
2. Gukora Cellulose: Mbere ya etherification, ibikoresho fatizo bya selile birashobora gukorwa muburyo bwo gukora kugirango byongere imbaraga kandi bigerweho nyuma yo guhindura imiti.
3. Uburyo bwa Etherification: Gahunda ya etherification ikubiyemo reaction ya selile hamwe na okiside ya Ethylene (EO) cyangwa Ethylene chlorohydrin (ECH) imbere ya catalizike ya alkaline. Iyi ntambwe itangiza hydroxyethyl matsinda kumugongo wa selile, itanga HEC.
4. Kwezwa no Kugarura: Nyuma ya etherification reaction, ibicuruzwa bya HEC biteye intambwe bigenda bisukurwa kugirango bikureho umwanda, reagent zidakorwa, nibicuruzwa. Inzira yo kugarura irashobora kandi gukoreshwa mugusubirana imyanda no gutunganya imyanda.

Hasi:

1. Gutegura no Guteranya: Hasi yumusaruro, HEC yinjijwe muburyo butandukanye hamwe nibindi bivangwa mubikorwa byihariye. Ibi birashobora kuvanga HEC hamwe nizindi polymers, inyongeramusaruro, nibindi bintu kugirango ugere kubintu byifuzwa nibikorwa biranga.
2. Gukora ibicuruzwa: Ibicuruzwa byateguwe birimo HEC bikozwe mubikorwa nko kuvanga, gusohora, kubumba, cyangwa guta, bitewe nibisabwa. Ingero z'ibicuruzwa byo hasi zirimo amarangi, ibifuniko, ibifatika, ibicuruzwa byita ku muntu, imiti, n'ibikoresho byo kubaka.
3. Gupakira no gukwirakwiza: Ibicuruzwa byarangiye bipakirwa mubikoresho cyangwa gupakira byinshi bikwiranye no kubika, gutwara, no gukwirakwiza. Ibi birashobora kubamo kuranga, kuranga, no kubahiriza ibisabwa kugirango umutekano wibicuruzwa namakuru.
4. Gusaba no Gukoresha: Abakoresha ba nyuma n'abaguzi bakoresha ibicuruzwa birimo HEC mubikorwa bitandukanye, bitewe na porogaramu yihariye. Ibi birashobora kubamo gushushanya, gutwikisha, guhuza ibifatika, kwita kubantu kugiti cyabo, gukora imiti, kubaka, nibindi bikorwa byinganda.
5. Kujugunya no gutunganya: Nyuma yo gukoreshwa, ibicuruzwa birimo HEC birashobora kujugunywa hakoreshejwe uburyo bukwiye bwo gucunga imyanda, bitewe n’amabwiriza y’ibanze ndetse n’ibidukikije. Amahitamo yo gusubiramo arashobora kuboneka kubikoresho bimwe kugirango ugarure ibikoresho byagaciro.

Muri make, ibyiciro byo hejuru byumusaruro wa HEC birimo ibikoresho fatizo biva mu mahanga, gukora selile, gukora etherification, no kwezwa, mugihe ibikorwa byo hasi birimo gukora, gukora, gupakira, gukwirakwiza, kubishyira mu bikorwa, no kujugunya / gutunganya ibicuruzwa birimo HEC. Byombi hejuru no kumanuka inzira nibice bigize urwego rwo gutanga no guha agaciro agaciro HEC.
