Selulosi Etha (HPMC,MC,HEC,EC,HPC,CMC,PAC)

Ma cellulose ethers ndi gulu la ma polima osungunuka m'madzi omwe amachokera ku cellulose, polima yachilengedwe yomwe imapezeka m'makoma a cellulose. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kukhuthala, kukhazikika, kupanga mafilimu, komanso kusunga madzi. Nazi mwachidule mitundu ina yodziwika bwino ya ma cellulose ethers:

1. Hydroxypropyl Methylcellulose (HPMC): HPMC ndi etha ya cellulose yosunthika yomwe imagwiritsidwa ntchito kwambiri pomanga, mankhwala, chisamaliro chamunthu, ndi mafakitale azakudya. Amadziwika chifukwa chosunga bwino madzi, kukhuthala, komanso kupanga mafilimu. HPMC amagwiritsidwa ntchito ngati thickener, binder, ndi rheology modifier mu matope, zomatira matailosi, mapiritsi amankhwala, zodzoladzola, ndi zakudya.
2. Methylcellulose (MC): MC ndi yofanana ndi HPMC koma ili ndi digiri yochepa yolowa m'malo ndi magulu a methyl. Amagwiritsidwa ntchito m'malo omwe kusungirako madzi ocheperako komanso kukhuthala kumafunika, monga popanga mankhwala, njira za ophthalmic, komanso ngati zowonjezera muzakudya.
3. Hydroxyethyl Cellulose (HEC): HEC ndi ether ina yomwe imagwiritsidwa ntchito kwambiri pa cellulose yomwe imadziwika chifukwa cha kusunga bwino madzi komanso kukhuthala. Amagwiritsidwa ntchito kwambiri m'zinthu zomangira monga utoto, zokutira, zomatira, komanso m'zinthu zosamalira anthu monga ma shampoos, mafuta odzola, ndi zopakapaka.
4. Ethyl Cellulose (EC): EC ndi cellulose ether yosinthidwa ndi magulu a ethyl. Amagwiritsidwa ntchito makamaka m'mankhwala, zokutira, ndi ntchito zapadera zomwe zimapangidwira kupanga mafilimu, zotchinga, komanso kutulutsa kosalekeza ndizopindulitsa. EC nthawi zambiri ntchito ngati ❖ kuyanika zakuthupi kwa mapiritsi ndi pellets mu mankhwala formulations.
5. Ma cellulose a Hydroxypropyl (HPC): HPC ndi cellulose etha yosinthidwa ndi magulu a hydroxypropyl. Nthawi zambiri amagwiritsidwa ntchito ngati thickener, binder, and film-forming agent pazamankhwala, zinthu zowasamalira, komanso pazakudya. HPC imapereka kusungunuka kwabwino kwambiri, kuwongolera kukhuthala, komanso kukhazikika pamayankho amadzi.
6. Carboxymethyl Cellulose (CMC): CMC ndi cellulose ether yosungunuka m'madzi yochokera ku cellulose ndi carboxymethylation. Amagwiritsidwa ntchito kwambiri ngati thickener, stabilizer, ndi binder muzakudya, mankhwala, zinthu zosamalira anthu, komanso ntchito zamafakitale. CMC imapanga mayankho omveka bwino, owoneka bwino ndipo nthawi zambiri amagwiritsidwa ntchito ngati chowonjezera mu sosi, mavalidwe, ndi kuyimitsidwa pakamwa.
7. Polyanionic Cellulose (PAC): PAC ndi cellulose ether yosinthidwa ndi magulu anionic, makamaka magulu a carboxymethyl kapena phosphonate. Amagwiritsidwa ntchito ngati chowonjezera chowongolera kutayika kwamadzimadzi pakubowola kwamafuta ndi gasi. PAC imathandizira kuchepetsa kutayika kwamadzimadzi, kuwongolera kukhuthala, ndikukhazikitsa matope obowola pansi pa kutentha kwambiri komanso kupanikizika kwambiri.

Ma cellulose ethers awa amapereka magwiridwe antchito ndi magwiridwe antchito osiyanasiyana m'mafakitale osiyanasiyana, zomwe zimathandizira kuti magwiridwe antchito, kukhazikika, ndi mtundu wazinthu zambiri komanso kapangidwe kake.
