Hari ubwoko butandukanye bwa selulose, kandi ni ubuhe budasa mu mikoreshereze yabwo?

Selulosi ni polymeri karemano ikoreshwa mu buryo bwinshi kandi bwinshi iboneka mu nkuta z'uturemangingo tw'ibimera, itanga inkunga y'imiterere n'ubudahangarwa. Igizwe n'ibice bya glucose bihujwe binyuze mu migozi ya β-1,4-glycosidic. Nubwo selulosi ubwayo ari ikintu kimwe, uburyo itunganywa n'uburyo itunganywamo butuma habaho ubwoko butandukanye bufite imiterere n'ikoreshwa bitandukanye.

1. Selilulose ya Microcrystalline (MCC):

MCCbikorwa binyuze mu kuvura insinga za selulose ukoresheje aside mineral, bigatuma habaho uduce duto twa crystalline.
Ikoreshwa: Ikoreshwa cyane nk'umuti ugabanya ubukana, uvanga, kandi ugakuraho uburozi mu miti nka ibinini na kapsule. Kubera imiterere yayo idakora neza kandi ikanatsindagira neza, MCC ituma imiti ikwirakwira mu buryo bumwe kandi yorohereza isohoka ry'imiti.

2. Asetate ya selulose:

Asetate ya selulosi iboneka binyuze mu gukora asetate ya selulosi ikoresheje aside asetiki cyangwa aside asetiki.
Ikoreshwa: Ubu bwoko bwa selulose bukunze gukoreshwa mu gukora imigozi yo mu myenda, harimo imyenda n'imyenda. Bukoreshwa kandi mu gukora filters z'itabi, filime y'amafoto, n'ubwoko butandukanye bw'amatafari bitewe nuko bushobora kwinjira mu buryo buto.

3. Ethylcellulose:

Ethylcellulose ikomoka kuri cellulose ikoresheje ethyl chloride cyangwa ethylene oxide.
Ikoreshwa: Imiterere yayo myiza yo gukora filime no kudahura n'ibintu bihumanya ikirere bituma ethylcellulose ikoreshwa mu gusiga ibinini bya farumasi, bigatuma imiti isohoka neza. Byongeye kandi, ikoreshwa mu gukora irangi, kole, n'ibindi bikoresho byihariye.

4. Hydroxypropyl Methylcellulose (HPMC):

HPMCikorwa binyuze mu gusimbuza amatsinda ya hydroxyl ya cellulose n'amatsinda ya methyl na hydroxypropyl.
Ikoreshwa: HPMC ikora nk'ikintu gikomeza ubushyuhe, gitera imbaraga, kandi gitera imbaraga mu nganda zitandukanye, harimo ibiribwa, amavuta yo kwisiga, n'imiti. Ikunze kuboneka mu bikoresho byo kwiyitaho nk'amavuta yo kwisiga, amavuta yo kwisiga, n'amavuta yo kwisiga, ndetse no mu biryo nk'isosi, isosi, na ice cream.

5. Selilulose ya Sodium Carboxymethyl (CMC):

CMC ikorwa binyuze mu kuvura selulosi hakoreshejwe aside chloroacetic na alkali.
Ikoreshwa: Kubera ubushobozi bwayo bwo gushonga no gukomera mu mazi menshi,CMCikoreshwa cyane nk'uburyo bwo gupima ubuziranenge bw'ibiryo, imiti, n'inganda. Ikunze kuboneka mu biryo bitetse, mu mata, mu bwoya bw'amenyo, no mu isabune.

6. Nitrocellulose:

Nitrocellulose ikorwa na nitrating cellulose ivanze na aside nitrike na aside sulfurike.
Ikoreshwa: Ikoreshwa cyane cyane mu gukora ibisasu, lacquers, na pulasitiki za celluloid. Lacquers zishingiye kuri nitrocellulose zikunzwe cyane mu gutunganya imbaho ​​no gusiga irangi ry'imodoka bitewe nuko zima vuba kandi zifite imiterere ihanitse.

7. Selilulose ya bagiteri:

Selulose ya bagiteri ikorwa n'ubwoko bumwe na bumwe bwa bagiteri binyuze mu guhinga.
Imikoreshereze: Imiterere yayo idasanzwe, harimo ubuziranenge bwinshi, imbaraga zo gukurura, no guhuza n'ibinyabuzima, bituma cellulose ya bagiteri igira akamaro mu bikorwa bya siyansi nko gupfuka ibisebe, gukaraba imiterere y'inyama, no gutanga imiti.

Ubwoko butandukanye bwa selulose butanga uburyo butandukanye bwo gukoreshwa mu nganda zitandukanye, harimo imiti, imyenda, ibiribwa, amavuta yo kwisiga, n'inganda. Buri bwoko bufite imiterere yihariye ituma bukoreshwa mu buryo bwihariye, kuva ku gutanga inkunga y'imiterere mu binini bya farumasi kugeza ku kunoza imiterere y'ibikomoka ku biribwa cyangwa gukora nk'ubundi buryo burambye mu ikoranabuhanga rya biotechnology. Gusobanukirwa aya tandukaniro bituma guhitamo ubwoko bwa selulose buhuye n'ibisabwa mu mikorere itandukanye.
