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

Cellulose ndi polima wachilengedwe wosunthika komanso wochulukirapo wopezeka m'makoma a zomera, omwe amapereka chithandizo chokhazikika komanso chokhazikika. Amapangidwa ndi mayunitsi a glucose olumikizidwa pamodzi kudzera pa ma β-1,4-glycosidic bond. Ngakhale kuti cellulose yokha ndi chinthu chofanana, momwe imapangidwira ndikusinthidwa kumabweretsa mitundu yosiyanasiyana yokhala ndi katundu ndi ntchito zosiyanasiyana.

1.Microcrystalline Cellulose (MCC):

MCCamapangidwa pochiza ulusi wa cellulose ndi mineral acid, zomwe zimapangitsa tinthu tating'ono ta crystalline.
Ntchito: Amagwiritsidwa ntchito ngati bulking wothandizira, binder, ndi disintegrant mu mankhwala formulations monga mapiritsi ndi makapisozi. Chifukwa cha chikhalidwe chake chopanda mphamvu komanso kupanikizana kwakukulu, MCC imatsimikizira kugawidwa kwa mankhwala ofanana ndikuthandizira kutulutsidwa kwa mankhwala.

2. Cellulose Acetate:

Cellulose acetate imapezeka mwa acetylating cellulose ndi acetic anhydride kapena acetic acid.
Ntchito: Mtundu uwu wa cellulose umagwiritsidwa ntchito popanga ulusi wopangira nsalu, kuphatikiza zovala ndi upholstery. Amagwiritsidwanso ntchito popanga zosefera za ndudu, filimu yojambula zithunzi, ndi mitundu yosiyanasiyana ya nembanemba chifukwa cha mawonekedwe ake osavuta.

3.Ethylcellulose:

Ethylcellulose imachokera ku cellulose pochita ndi ethyl chloride kapena ethylene oxide.
Ntchito: Zake zabwino kupanga filimu katundu ndi kukana zosungunulira organic kupanga ethylcellulose oyenera ❖ kuyanika mapiritsi mankhwala, kupereka ankalamulira kumasulidwa kwa mankhwala. Kuphatikiza apo, amagwiritsidwa ntchito popanga inki, zomatira, ndi zokutira zapadera.

4.Hydroxypropyl Methylcellulose (HPMC):

Mtengo wa HPMCamapangidwa polowetsa magulu a hydroxyl a cellulose ndi magulu a methyl ndi hydroxypropyl.
Ntchito: HPMC akutumikira monga thickener, stabilizer, ndi emulsifier m'mafakitale osiyanasiyana, kuphatikizapo chakudya, zodzoladzola, ndi mankhwala. Nthawi zambiri amapezeka m'zinthu zosamalira anthu monga mafuta odzola, mafuta odzola, mafuta odzola, komanso m'zakudya monga sosi, mavalidwe, ndi ayisikilimu.

5.Sodium Carboxymethyl Cellulose (CMC):

CMC imapangidwa pochiza cellulose ndi chloroacetic acid ndi alkali.
Ntchito: Chifukwa cha kusungunuka kwake kwamadzi komanso kukhuthala kwake,CMCamagwiritsidwa ntchito kwambiri ngati stabilizer ndi viscosity modifier muzakudya, mankhwala, ndi mafakitale. Nthawi zambiri amapezeka muzophika, mkaka, mankhwala otsukira mano, ndi zotsukira.

6.Nitrocellulose:

Nitrocellulose amapangidwa ndi nitrate cellulose ndi osakaniza nitric acid ndi sulfuric acid.
Ntchito: Amagwiritsidwa ntchito makamaka popanga zophulika, zokokera, ndi mapulasitiki a celluloid. Ma lacquers opangidwa ndi nitrocellulose ndi otchuka pakumalizitsa matabwa ndi zokutira zamagalimoto chifukwa cha kuyanika kwawo mwachangu komanso gloss yayikulu.

7.Bacterial cellulose:

Bakiteriya cellulose amapangidwa ndi mitundu ina ya mabakiteriya kudzera mu nayonso mphamvu.
Kagwiritsidwe: Kapangidwe kake kapadera, kuphatikiza kuyeretsedwa kwakukulu, kulimba kwamphamvu, komanso kuyanjana kwachilengedwe, zimapangitsa cellulose ya bakiteriya kukhala yofunikira pazachilengedwe monga kuvala mabala, ma scaffolds opanga minofu, ndi njira zoperekera mankhwala.

Mitundu yosiyanasiyana ya cellulose imapereka ntchito zosiyanasiyana m'mafakitale osiyanasiyana, kuphatikiza mankhwala, nsalu, chakudya, zodzoladzola, ndi kupanga. Mtundu uliwonse uli ndi mawonekedwe ake apadera omwe amaupangitsa kukhala oyenera kugwiritsidwa ntchito mwapadera, kuyambira pakupereka chithandizo chamankhwala m'mapiritsi amankhwala mpaka kukulitsa kapangidwe kazakudya kapena kukhala njira yokhazikika mu sayansi yazachilengedwe. Kumvetsetsa kusiyana kumeneku kumathandizira kusankha koyenera kwa mitundu ya cellulose kuti ikwaniritse zofunikira zinazake pamagwiritsidwe osiyanasiyana.
