Ma Cellulose Derivative with Physical Properties & Extended Application

Ma cellulose ndi gulu losunthika lamagulu opangidwa kuchokera ku cellulose, yomwe ndi gawo lalikulu la makoma a cellulose. Zotengerazi zimapangidwa ndi kusintha kwa ma cellulose mamolekyu kuti asinthe zinthu zawo, zomwe zimapangitsa kuti pakhale ntchito zambiri m'mafakitale osiyanasiyana. Nazi zina zotuluka pa cellulose limodzi ndi mawonekedwe ake komanso ntchito zowonjezera:

1. Methylcellulose (MC):
   • Katundu Wathupi: Methylcellulose imasungunuka m'madzi ndipo imapanga mayankho omveka bwino, owoneka bwino. Ndiwopanda fungo, osakoma, komanso alibe poizoni.
   • Ntchito Zowonjezera:
     • Makampani a Chakudya: Amagwiritsidwa ntchito ngati zonenepa, zokhazikika, ndi zokometsera muzakudya monga sosi, soups, maswiti, ndi ayisikilimu.
     • Makampani Opanga Mankhwala: Amagwiritsidwa ntchito ngati binder, filler, kapena disintegrant mumipangidwe yamapiritsi komanso ngati viscosity modifier mumafuta am'mutu ndi mafuta odzola.
     • Makampani Omanga: Amagwiritsidwa ntchito ngati chowonjezera mumatope opangidwa ndi simenti, zomatira matailosi, ndi zinthu zopangidwa ndi gypsum kuti azitha kugwira bwino ntchito, kusunga madzi, komanso kumamatira.
2. Hydroxyethyl cellulose (HEC):
   • Katundu Wathupi: Hydroxyethylcellulose imasungunuka m'madzi ndipo imakhala yowoneka bwino pamayankho amatope pang'ono. Imawonetsa khalidwe la pseudoplastic, kutanthauza kuti kukhuthala kwake kumachepa pansi pa kumeta ubweya wa ubweya.
   • Ntchito Zowonjezera:
     • Zopangira Zosamalira Munthu: Zomwe zimagwiritsidwa ntchito ngati zokhuthala, zomangira, ndi filimu zakale mu zodzoladzola, ma shampoos, zowongolera, ndi zodzola.
     • Makampani Azamankhwala: Amagwiritsidwa ntchito ngati thickening wothandizira pakupanga madzi amkamwa komanso ngati mafuta opangira ma ophthalmic.
     • Utoto ndi zokutira: Amagwiritsidwa ntchito ngati rheology modifier kuwongolera kukhuthala ndikuwongolera magwiridwe antchito mu utoto wamadzi, zomatira, ndi zokutira.
3. Hydroxypropyl Methylcellulose (HPMC):
   • Katundu Wathupi: Hydroxypropyl methylcellulose imasungunuka m'madzi ndipo imapanga njira zomveka bwino komanso zopanda mtundu. Ili ndi mawonekedwe abwino opangira mafilimu ndipo imawonetsa kutenthetsa kwa gelation.
   • Ntchito Zowonjezera:
     • Makampani Omangamanga: Amagwiritsidwa ntchito kwambiri monga chokhuthala, chosungira madzi, ndi chomangira mumatope opangidwa ndi simenti, ma rendi, pulasitala, ndi zomatira matailosi.
     • Makampani Opanga Mankhwala: Amagwiritsidwa ntchito ngati matrix omwe kale anali m'machitidwe operekera mankhwala otulutsidwa komanso ngati chosinthira mamasukidwe amadzimadzi amkamwa.
     • Makampani a Chakudya: Amagwiritsidwa ntchito ngati chowonjezera, emulsifier, ndi chokhazikika muzakudya monga mkaka, zowotcha, ndi sosi.
4. Carboxymethylcellulose (CMC):
   • Katundu Wathupi: Carboxymethylcellulose imasungunuka m'madzi ndipo imakhala yomveka bwino pamayankho a turbid. Ili ndi mchere wabwino kwambiri komanso kulekerera kwa pH.
   • Ntchito Zowonjezera:
     • Makampani a Chakudya: Amagwiritsidwa ntchito ngati zonenepa, zokhazikika, ndi zokometsera muzakudya monga mavalidwe a saladi, sosi, mkaka, ndi zakumwa.
     • Makampani Opanga Mankhwala: Amagwiritsidwa ntchito ngati chophatikizira, chophatikizira, komanso chosinthira kukhuthala pamapangidwe amapiritsi, kuyimitsidwa kwapakamwa, ndi mayankho amaso.
     • Zopangira Zosamalira Munthu: Zimagwiritsidwa ntchito ngati chowonjezera komanso chokhazikika mumankhwala otsukira mano, zodzoladzola, ndi zosamalira tsitsi.

Izi ndi zitsanzo za zotumphukira za cellulose zomwe zili ndi thupi komanso kugwiritsa ntchito nthawi yayitali. Ma cellulose opangidwa ndi cellulose amapereka magwiridwe antchito osiyanasiyana ndipo amayamikiridwa chifukwa cha kusinthasintha kwawo, kuyanjana kwachilengedwe, komanso chilengedwe chokonda zachilengedwe.
