Kodi cellulose ndi chiyani?

Cellulose ndi banja la mankhwala opanga mankhwala ochokera ku cellulose, polymer achilengedwe omwe amapezeka m'makoma a cell a mbewu. Izi zimapangidwa kudzera mu kusintha kwamankhwala kwa mamolekyulu a cellulose kuyambitsa magulu osiyanasiyana ogwirira ntchito, zomwe zimapangitsa kuti mitundu ikuluikulu ikhale yosiyanasiyana. Cellulose, nthawi zambiri amagwiritsidwa ntchito m'makampani monga zomangamanga, mankhwala opangira mankhwala, chakudya, zodzoladzola, komanso chisamaliro chaumwini chifukwa cha mtundu wawo wosiyanasiyana. Nazi mitundu yodziwika bwino ya cellulose ndi kugwiritsa ntchito kwawo:

1. Methyl cellulose (MC):
   • Celyl cellulose imapangidwa pochiza cellulose ndi methyl chloride.
   • Imasungunuka m'madzi ndikupanga zomveka, zothetsera ma viscous.
   • MC imagwiritsidwa ntchito ngati thicker, Bander, ndi Stateer pomanga (mwachitsanzo, matope a simenti, ma gypsum-ady, ndi zinthu zaumwini, komanso zinthu zosamalira pandekha.
2. Hydroxyethyl cellulose (hec):
   • Volroxyathyl cellulose imapangidwa ndi cellulose ndi ethylene oxide kuti ayambitse magulu a hydroxyethyl.
   • Imasungunuka m'madzi ndikupanga zomveka, zothetsera ma viscous ndi zida zabwino zamadzi.
   • Hec imagwiritsidwa ntchito ngati thicker, rhelology osintha, ndi wothandizira makanema mu utoto, zomata, zopangidwa ndi anthu, komanso mankhwala.
3. Hydroxypypyl methyl cellulose (hpmc):
   • Hydroxypropyl celyl cellulose imapangidwa poyambitsa hydroxypropyl ndi methyl magulu am'madzi am'madzi a cellulose.
   • Zimawonetsa katundu wofanana ndi methyl cellulose ndi hydroxethyl cellulose, kuphatikizapo kusungunuka madzi, kuthekera kwamafilimu, komanso kusungidwa kwamafilimu.
   • HPMC imagwiritsidwa ntchito kwambiri pomanga (mwachitsanzo, ma tile amaluma, okonda, mankhwala omwe amadzipangitsa okhawo), komanso mu mankhwala, komanso zinthu zosamalira pandekha.
4. Carboxymethyl cellulose (cmc):
   • Carboxymethyl cellulose imachokera ku celluluse pochiza ndi sodium hydroxide ndi monochloroortic acid kuti iyambitse magulu a carboxymethyl.
   • Imasungunuka m'madzi ndikupanga zomveka, zothetsera ma viscous muli bwino kwambiri, zokhazikika, komanso madzi osasunga madzi.
   • CMC imagwiritsidwa ntchito ngati thicker, binder, ndi rheologle osintha pazakudya, mankhwala, zolemba, pepala, ndi zida zomanga.

Izi ndi zina mwa ma cellulose omwe amagwiritsidwa ntchito cellulose omwe ali ndi celluse, iliyonse yokhala ndi malo apadera ndi ntchito zamakampani osiyanasiyana. Cellulose ina yapadera imatha kukhalapo, yogwirizana ndi zofunikira mwatsatanetsatane m'mapulogalamu osiyanasiyana.
