Chemistry of MetholLel ™ CELALESES Edya

MethocesNdi mtundu wa cellulose etrs wopangidwa ndi Dow. Chuma ichi chimachokera ku cellulose, polymer wachilengedwe amapezeka mu makhoma a cell. Mictanzi ya methocel ™ imaphatikizapo kusintha kwa cellulose pochita bwino. Mitundu yoyamba ya methocel ™ imaphatikizapo hydroxypropyl (hpmc) ndi methyllulose (MC), iliyonse yokhala ndi mawonekedwe apadera. Nayi mwachidule za umagwirira wa methocel ™:

1. Hydroxypropyll Methylcellulose (HPMC):

• Kapangidwe:
  • HPMC ndi ma cellulose osungunuka ndi ma cellulose ndi zigawo ziwiri: hydroxypropyl (hp) ndi methyl (m) magulu.
  • Magulu a hydroxypyl amayambitsa magwiridwe antchito a hydrophilic, amathandizira kusandulika kwamadzi.
  • Magulu a methyl amathandizira kusungunuka kwathunthu ndikuwongolera katundu wa polymer.
• Kutengera Kwakufuna:
  • HPMC imapangidwa kudzera pakusinthika kwa cellulose ndi magulu a ma bulodi (ya hydroxypyl) ndi methyl chloride (yamagulu a methyl).
  • Zomwe zimachitika zimayendetsedwa mosamala kuti mukwaniritse kuchuluka kwa zolowa m'malo mwa hydroxypyl ndi methyl.
• Katundu:
  • HPMC imawonetsa kusungunuka kwamadzi madzi, mawonekedwe a makanema, ndipo amatha kupereka magetsi ovomerezeka m'mapulogalamu a mankhwala.
  • Mlingo wazokhazikika umakhudza mafakisoni a polymer, kusungidwa kwamadzi, ndi zinthu zina.

2. Methylcellulose (MC):

• Kapangidwe:
  • MC ndi ethel ether ndi methyl m'malo.
  • Ndizofanana ndi HPMC koma ilibe magulu a hydroxypyl.
• Kutengera Kwakufuna:
  • MC imapangidwa ndikuyamba kukhetsa cellulose ndi methyl chloride.
  • Zomwe zimachitika zimayang'aniridwa kuti mukwaniritse kuchuluka kwa zomwe mukufuna.
• Katundu:
  • MC ndi kusungunuka kwamadzi ndipo amagwiritsa ntchito mapulogalamu pa mankhwala, zomangamanga, ndi mafakitale.
  • Amagwiritsidwa ntchito ngati binder, thiccin, ndi kukhazikika.

3. Zofala Zofala:

• Madzi osungunuka: onse a HPMC ndi MC amasungunuka m'madzi ozizira, ndikupanga mayankho omveka bwino.
• Mapangidwe a makanema: Amatha kupanga mafilimu osinthika komanso owoneka bwino, ndikuwapangitsa kukhala othandiza pamapulogalamu osiyanasiyana.
• Kukula: Metholcel ™ cy cellose etrs imagwira ntchito yothandiza, imapangitsa ma viuni a mayankho.

4. Mapulogalamu:

• Mankhwala opangira mankhwala: Ntchito zophatikizika za piritsi, kumanga, ndi mapangidwe ake omasulidwa.
• Ntchito yomanga: olemba ntchito matope, zomata za matabwa, ndi zida zina zomanga.
• Chakudya: Kugwiritsidwa ntchito ngati otsatsa ndi okhazikika pazakudya.
• Kusamalira Kwawo: Kupezeka koosmetics, shampoos, ndi zinthu zina zosamalira pandekha.

Ma Umoyo a Metholcer ™ cy cellose ede imawapangitsa kugwiritsa ntchito zinthu zosiyanasiyana zogwiritsidwa ntchito ndi mapulogalamu osiyanasiyana, kupereka mphamvu pazachilengedwe, kusungidwa kwamadzi, ndi machitidwe ena ofunikira osiyanasiyana. Zomwe zimapangitsa kuti zinthu zizigwirizana ndi kusintha kuchuluka kwa zolowa m'malo ena.
