Nigute ushobora gukora selile ether?

Gukora abahanga ba selile bikubiyemo guhinduranya selile kamere, mubisanzwe bikomoka kuri pulp yimbaho ​​cyangwa ipamba, binyuze murukurikirane rwibitekerezo bya shimi. Ubwoko bukunze kugaragara kuri selile barimo methyl selile (mc), hydroxyAyyl Methypropyl Methymethyl Methymethyl Metwoll Methulose (CMC), n'abandi. Inzira nyayo irashobora gutandukana gushingiye kuri selile yihariye ya selile ikorwa, ariko intambwe rusange zirasa. Dore incamake yoroshye:

Intambwe rusange zo gukora selile ya selile:

1. Inkomoko ya selile:

• Ibikoresho byo gutangiriraho ni selile isanzwe, mubisanzwe biboneka muri pulp yimbaho ​​cyangwa ipamba. Ubugari buri muburyo bwa selile ya feri.

2. Alkalisation:

• Cellulose yafatwa nigisubizo cya alkaline, nka sodium hydroxide (naoh), kugirango akore amatsinda ya hydroxyl kumunyururu wa selile. Iyi ntambwe ya alkalisation ningirakamaro kugirango yongere kugenda.

3. Guhangana:

• Ubugari bwa Alkalize bukorwa kurokorwa, aho amatsinda atandukanye ya Ether yamenyeshejwe kuri selile. Ubwoko bwihariye bwitsinda rya ether yatangijwe (methyl, hydroxyethyyl, hydroxyIthyl, HydroxyPropyl, Carboxymethyl, n'ibindi) biterwa na selile wifuza ether.
• Inzira yo Guhuza ikubiyemo reaction ya selile hamwe nibikoresho bikwiye, nka:
  • Kuri Methyl selile (MC): Kuvura na Dimethyl Sulfate cyangwa methyl chloride.
  • Kuri HydroxyAythyl Cellulose (HEC): Kovu na Esylene okiside.
  • Kuri HydroxyPropyl Methyl Cellulose (HPMC): Kuvura hamwe na propalene okiside na methyl chloride.
  • Kuri Carboxymethyl selile (CMC): Kuvura na sodium chlorocetate.

4. Kutabogama no gukaraba:

• Nyuma yo gutora, biva kuri selile yavuyemo ubusanzwe butabogamye kugirango bakureho alkali. Ibicuruzwa noneho byogejwe kugirango bikureho umwanda nibicuruzwa.

5. Kuma no gusya:

• Ubugari bwa selile bwumye kugirango bakureho ubushuhe burenze hanyuma bakinginga ifu nziza. Ingano yinshi irashobora kugenzurwa ukurikije porogaramu igenewe.

6. Igenzura ryiza:

• Ibicuruzwa byanyuma bya firigo byanyuma bireba ibizamini byujuje ubuziranenge kugirango bihuze ibisobanuro byihariye, harimo vicosity, ibirimo ubushuhe, kugabura ingano, nibindi bintu bifatika.

Ni ngombwa kumenya ko umusaruro wa eleralese ukorwa nabakora byihariye bakoresheje inzira zigenzurwa. Ibihe byihariye, reagents, nibikoresho byakoreshejwe birashobora gutandukana ukurikije imitungo yifuzwa na selile hamwe nibisabwa. Byongeye kandi, ingamba z'umutekano ni ngombwa mugihe cyo guhindura imiti.
