Nubuhe buryo bwo kubyara bwa methylcellse?

Methycellseliulose (MC) ni ugukemura amazi yakoreshejwe mubiribwa cyane mu biribwa, imiti, imiti ya buri munsi, kubaka n'izindi nganda. Inzira yacyo ikubiyemo intambwe nyinshi, cyane cyane harimo gukuramo selile, kwitwara neza, kumisha no guhonyora.

1. Gukuramo selile
Ibikoresho byibanze byibanze bya methylcellse ni selile isanzwe, mubisanzwe bikomoka kuri pulp cyangwa ipamba. Ubwa mbere, inkwi cyangwa ipamba bikorerwa urukurikirane rwibanze kugirango ukureho umwanda (nka lignn, resin, poroteyine, nibindi) kugirango ubone selile nziza. Uburyo busanzwe bwo kwirinda harimo uburyo bwa aside hamwe nuburyo bworoshye. Muburyo bwa acide, ibiti cyangwa paki ya sodium bivurwa na sodium hydroxide (naoh) cyangwa ibindi bisubizo bya alkaline kugirango bishongeshejwe ligsolve nindi mbaraga, bityo ukuyemo selile.

2. Impinduka ihindagurika kwa selile
Ibikurikira, imyifatire ya methylation (reaction yabuze) irakorwa kugirango itegure methycellse. Intambwe y'ibanze yo gutandukanya ni ugutwara ikariro hamwe n'umukozi wa methitlating (mubisanzwe methyl chloride, methyl iyode, nibindi) kugirango ubone methylcellse. Igikorwa cyihariye ni ibi bikurikira:

Guhitamo reaction Solvent: Polan Porvents (nkamazi, ethanol cyangwa ikibazo kivanze cyamazi n'inzoga) ndetse na sodium hydroxipide
Ibisabwa: reaction ikorwa ku bushyuhe hamwe nigitutu runaka, kandi ubushyuhe busanzwe bwo gukora ni 50-70 ° c. Mugihe cyo kubyitwaramo, methyl chloride yitawe na hydroxyl (-oh) mumatsinda ya selile kugirango ayihindure muri methyl selilese.
Kugenzura reaction: Umubyimbatsi wijimye bisaba kugenzura neza igihe nubushyuhe. Igihe kirekire cyo kwifata cyangwa ubushyuhe bwinshi bushobora gutera ubushyuhe bwa selile, mugihe ubushyuhe buke cyane cyangwa butuzuye bushobora kuganisha ku cyambu budahagije, bigira ingaruka kumikorere ya methyl selile selile selile selile.

3. Kutabogama no gukora isuku
Nyuma yo kugirwa reaction irangiye, ibishambaro bidasubirwaho kandi umusemburo birashobora kuguma mu gicuruzwa cya Cellyl, kigomba kutabogama kandi kigasukurwa. Inzira yo kutabogama mubisanzwe zikoresha igisubizo cya acide (nko gukemura acide acide) kugirango utandukire ibintu bya alkaline mubicuruzwa. Inzira yogusukura ikoresha amazi menshi cyangwa inzoga kugirango ukureho ibishushanyo, imiti idakemutse hamwe nibicuruzwa nyuma yibya reaction kugirango yere neza ibicuruzwa byanyuma.

4. Kuma no guhonyora
Nyuma yo gukaraba, methylcellse mubisanzwe muri paste cyangwa gel, niko igomba gukama kugirango ubone ibicuruzwa byafashwe. Hariho inzira nyinshi zo gukama, kandi abantu bakoreshwa bakunze kuba barimo gukama, gukonjesha byumye no kumisha. Mugihe cyo kumisha, ubushyuhe nubushyuhe bugomba kugenzurwa neza kugirango birinde kubora cyangwa kwangiza imitungo ya Gel.

Nyuma yo gukama, Methylcellsellsellse igomba guhonyora kugirango igere ku bunini busabwa. Inzira yo guhoshya ubusanzwe irangizwa na jye na air llung cyangwa gusya. Mugucunga ingano yacitse, igipimo cyo gusebanya hamwe nibiranga methylcellsellse birashobora guhinduka.

5. Kugenzura no gupakira ibicuruzwa byanyuma
Nyuma yo guhonyora, methylcellse igomba kugenzurwa neza kugirango igerweho ko yujuje ibisobanuro bya tekiniki. INGINGO ZISANZWE ZISHYIRA MU BIKORWA:

Ibirimo byuzuye: ubushuhe bukabije bwa methylcellsellse bizagira ingaruka kumihaniko no kubika.
Ikwirakwizwa ryimiterere: ingano no gukwirakwiza ibice bizagira ingaruka kubikesha bya methylcellse.
Urwego rwa Methylation: Urwego rwa Methylation ni ikintu cy'ingenzi cyo gusuzuma ubwiza bwa Methycelllllliulose, bigira ingaruka ku kuntu kwikebagura no gusaba.
Kukecururizwa no gukemurwa: Kudakemurwa no gusya bya methylcellllse ni ibipimo byingenzi mubikorwa byayo, cyane cyane mubuvuzi nubuvuzi.
Nyuma yo gutanga ubugenzuzi, ibicuruzwa bizapakirwa hakurikijwe ibikenewe bitandukanye, mubisanzwe mumifuka ya pulasitike cyangwa imifuka yimpapuro, kandi biranga nimero yakazi, ibisobanuro, itariki yumusaruro nandi makuru.

6. Kurinda ibidukikije n'umutekano
Mu gihe cyo kubyara kwa Methyl, ingamba zihagije zo kurengera ibidukikije zigomba gufatwa, cyane cyane ku miti kandi idakoreshwa mu buryo bwo gukora. Nyuma yimyitwarire, imyanda yuzuye kandi imyanda igomba kuvurwa kugirango yirinde guteza ibintu nkibidukikije. Byongeye kandi, imiti yimiti mubikorwa byumusaruro bigomba gukorwa neza muburyo bwo gukora umutekano kugirango umutekano w'abakozi.

Inzira yumusaruro wa methyl selile ikubiyemo ahanini ikuramo selile, imyigaragambyo ya metylation, gukaraba no kutabogama, gukama no guhonyora. Buri sano ifite ingaruka zingenzi kurwego rwibicuruzwa byanyuma, kugenzura no gukurikirana no gukurikirana muburyo bwo gukora bunegura cyane. Binyuze muriyi nzira, methyl selile iterana isaba ibisabwa bitandukanye.
