Hydroxypropyll methylcellulose zambiri

Hydroxypypyl methylcellulose. Apa ndi chidziwitso chatsatanetsatane cha hydroxypropyl methylcellulose:

1. Kapangidwe ka mankhwala:
   • HPMC imachokera ku cellulose, polymer yachilengedwe imapezeka mu khoma la cell.
   • Imakhala ndi kusintha kwamankhwala ndi Propylene oxide ndi methyl chloride, komwe kumatsogolera ku zowonjezera hydroxypropyl ndi magulu a methyl ku cellulose.
2. Katundu wathupi:
   • Nthawi zambiri zoyera pang'ono pang'ono pofa ndi ufa wokhala ndi mawonekedwe a fibrous kapena granlar.
   • Fungo lopanda fungo.
   • Sungunuka m'madzi, ndikupanga yankho lomveka bwino komanso lopanda utoto.
3. Mapulogalamu:
   • Mankhwala ogwiritsa ntchito mankhwala: ogwiritsidwa ntchito ngati mapiritsi ofesa m'mapiritsi, makapisozi, ndi kuyimidwa. Ntchito monga bander, kunyalanyaza, kusinthika kwa usus, ndi kafukufuku wakale.
   • Makampani omanga: opezeka muzogulitsa ngati ma tile azithunzi, matope, ndi zinthu zama gypsyam. Kumathandizira kugwirira ntchito, kusungidwa kwamadzi, komanso kutsatira.
   • Makampani Opanga Chakudya: Kuchita ngati Thicner, chisunthi, ndi emulsiferier mu zinthu zosiyanasiyana, zomwe zimathandizira kapangidwe kake ndi kukhazikika.
   • Zodzikongoletsera ndi zinthu zosamalira payekha: zogwiritsidwa ntchito mu zotupa, zonona, ndi mafuta odzola komanso kulimbitsa thupi.
4. Zogwira:
   • Mapangidwe a filimu: HPMC imatha kupanga mafilimu, ndikupangitsa kuti ikhale yofunika pantchito monga zokutira za piritsi komanso zodzikongoletsera.
   • Kusintha kwa Vission: Zimasintha mapangidwe a mayankho, kupereka ulamuliro pazinthu zamtundu wa mapangidwe.
   • Kusungidwa kwamadzi: Kugwiritsa ntchito zida zomanga kuti zisunge madzi, kukonzanso kugwirira ntchito, komanso zodzikongoletsera zodzikongoletsera kuti zithandizire chinyezi.
5. Madigiri olowa m'malo:
   • Mlingo wa cholowa m'malo mwake amatanthauza kuchuluka kwa hydroxypyl ndi methyl magulu omwe ali ndi khungu lililonse mu cellulose unyolo.
   • Makulidwe osiyanasiyana a HPMC akhoza kukhala ndi madigiri osiyanasiyana, zomwe zimakhudza katundu ngati kusungunuka ndi kusungunuka kwamadzi.
6. Chitetezo:
   • Nthawi zambiri amawoneka otetezeka kuti agwiritsidwe ntchito mankhwala, chakudya, komanso zinthu zosamalira payekha mukamagwiritsidwa ntchito malinga ndi malangizo.
   • Maganizo a chitetezo amadalira zinthu monga kuchuluka kwa zolowa m'malo mwake.

Mwachidule, hydroxypropyl methylcellulose (hpmc) ndi polymer polymer yogwiritsidwa ntchito kwambiri pamafakitale osiyanasiyana. Kusungunuka kwake m'madzi, luso lake lopanga mafilimu, komanso kusanjikira zimapangitsa kukhala chofunikira chofunikira mu mankhwala opangira mankhwala, zinthu zomanga, zinthu zina, ndi zodzola. Gawolo ndi mawonekedwe a HPMC itha kukhala yogwirizana kuti ikwaniritse zofunikira zosiyanasiyana.
