I-Methyl Selelose (MC) yenziwe ngemveliso yendalo

I-methyl seluplose (MC) kukukhupha i-sellyulose, engu-polymer yendalo efumaneka kwiindonga zeseli. I-seluplose yenye yezona zinto zibalulekileyo zezinto ezisemhlabeni, zifunyenwe kwi-pulp kunye ne-cotton fibers. I-MC iqukethelwe kwi-seluplose ngothotho lwemichiza ebandakanya ukwenziwa kwamaqela e-hydroxyl (---------------) kwimolekyuli ye-selselose kwimolekyuli ye-sellyl (-Ch3).

Ngelixa i-MC ngokwayo yikhowudi eguqulweyo yekhefu, isixhobo sayo eluhlaza, iseluplose, sivela kwimithombo yendalo. I-seluplose inokukhutshwa kwizinto ezahlukeneyo zezityalo, kubandakanya neenkuni, i-cotton, ihemp, kunye nezinye izityalo ezinamaqhina. I-seluplose iphantsi kwenkqubo yokususa ukungcola kwaye iguqule ibe yifom efanelekileyo yokuveliswa kwe-MC.

Nje ukuba kufunyenwe i-seluplose, iphantsi kose-etheriya ukwazisa amaqela e-methyl kwi-selsulose ngasemva, ekhokelela ekumoyeni kwe-methyl sellulose. Le nkqubo ibandakanya ukunyanga i-seluplose ngomxube we-sodium hydroxide kunye ne-methyl chloride phantsi kweemeko ezilawulwayo.

I-methyl sethyl seluplose intle kumhlophe ukuya kwi-off-off-off-off-off-off-engenakuthelekiswa nanto inyibilikisi emanzini abandayo kwaye yenze isisombululo se-viscous. Isetyenziswe ngokubanzi kumashishini ahlukeneyo, kubandakanya ukutya, ukhathalelo lobuqu, kunye nolwakhiwo, ukuzinzisa, ukuzinzisa, kunye nokuzinzisa iifilimu.

Ngelixa i-MC yikhowudi eguqulweyo yekhemidileyo, ithathwa kwi-selupose yendalo, iyenza ibe yi-biodegrade enokukhetha kunye nokusingqongileyo enobuhlobo kwizicelo ezininzi.
