Pali mitundu ingapo ya cellulose, ndipo pali kusiyana kotani pakugwiritsa ntchito kwawo?

Cellulose ndi yolimba ndi polymer yachilengedwe yochulukirapo yomwe imapezeka m'makhoma a cell, omwe amathandizidwa ndi mawonekedwe. Imapangidwa ndi zigawo za glucose zomwe zimalumikizidwa pamodzi ndi β-1,4-glycosidic. Pomwe ma cellulose omwewo ndi chinthu chowoneka bwino, momwe amapangidwira komanso kukonzedwa mitundu yosiyanasiyana ndi malo osiyanasiyana ndi ntchito.

1.Tracrocrystalline cellulose (MCC):

Mcoimapangidwa ndikuchiritsa ulusi wa cellulose wokhala ndi michere ya mchere, zomwe zimapangitsa tinthu tating'onoting'ono, ma crystalline.
Kugwiritsa Ntchito: Imagwiritsidwa ntchito kwambiri ngati wothandizira ng'ombe, womenyera, ndi kusokonekera mu mankhwala monga mapiritsi ndi makapisozi. Chifukwa cha chilengedwe chake chilengedwe komanso kusiyana kwakukulu, MCC imawonetsa kugawa kwa mankhwala osokoneza bongo ndikuthandizira kumasulidwa kwamankhwala.

2.Clalilose acetate:

Celluluse acetate imapezeka ndi celtulose cellulose yokhala ndi acetic terhydride kapena acetic acid.
Kugwiritsa Ntchito: Ma cellulose omwe nthawi zambiri amagwiritsidwa ntchito popanga ulusi wa zikwangwani, kuphatikizapo zovala ndi upholstery. Amagwiranso ntchito popanga zosefera ndudu, makanema ojambula, ndi mitundu yosiyanasiyana ya nembanemba chifukwa cha chikhalidwe chake.

3.thyllulose:

Ethylcellulose imachokera ku celluluse poutani ndi ethyl chloride kapena ethylene oxide.
Kugwiritsa Ntchito: Katundu wake wabwino kwambiri wamakanema ndi kukana kwa orthyllulose kuti akhale woyenera kumatunga mapiritsi a mankhwala opangira mankhwala, amapereka mphamvu mankhwala. Kuphatikiza apo, amagwiritsidwa ntchito popanga inks, zomata, ndi zokutira zapadera.

4.hydroxypypyl methylcellulose (hpmc):

Hpmcimapangidwa ndi mitundu ya hydroxyl ya cellulose ndi methyl ndi hydroxypyl.
Kugwiritsa Ntchito: HPMC imagwira ngati thickir, rukanitse, ndi emulsifier m'makampani osiyanasiyana, kuphatikizapo chakudya, zodzola zodzola, zodzoladzola, ndi mankhwala osokoneza bongo. Nthawi zambiri imapezeka pazinthu zosamalira anthu monga zotupa, mafuta, mafuta onga zakudya monga msuzi, zovala, ndi ayisikilimu.

5.sodium Carboxymethyl cellulose (CMC):

CMC imapangidwa ndi kuchiritsa cellulose ndi chloroocetic asidi ndi alkali.
Kugwiritsa ntchito: chifukwa cha madzi ake osungunuka ndi mphamvu,Cmcimagwiritsidwa ntchito kwambiri ngati chokhazikika komanso kusinthika kosasunthika mu chakudya, mankhwala opangira mankhwala, ndi ntchito zamagetsi. Amapezeka m'zinthu zophika, zinthu zamkaka, zonona, ndi zotumbuzi.

6.Nastrocellulose:

Nitrocellulose amapangidwa ndi cellulose yophatikiza ndi nitric acid ndi sulfuric acid.
Kugwiritsa Ntchito: Amagwiritsa ntchito popanga zophulika, mabungwe, ndi celluliod plastics. Nyimbo za Nitrocellulose ndizotchuka nkhuni kumaliza nkhuni komanso zokutira zamagalimoto chifukwa chowuma mwachangu komanso katundu wambiri.

7.bacterial cellulose:

Bacterial Cellulose imapangidwa ndi mitundu ina ya mabakiteriya kudzera mu mantha.
Kugwiritsa Ntchito: Malo ake apadera, kuphatikiza mphamvu yayitali, komanso mabaculoterial cellulose othandiza monga mavalidwe azomwe amavala, ndi ma straces a mankhwala osokoneza bongo.

Mitundu yosiyanasiyana ya cellulose imagwiritsa ntchito ntchito zosiyanasiyana m'mafakitale osiyanasiyana, kuphatikizapo mafakitale, kuphatikiza, chakudya, zodzola, ndi kupanga. Mtundu uliwonse umakhala ndi zinthu zapadera zomwe zimayenera kugwiritsidwa ntchito mwachindunji, kuyambira popereka chithandizo m'mapale opangira mankhwala kuti athandize kapangidwe ka zinthu zina kapena kugwira ntchito ngati njira ina yosasunthika. Kumvetsetsa izi kumathandizanso kusankha mitundu ya cellulose kuti akwaniritse zofunika pa ntchito zosiyanasiyana.
