Chimie ya methicel ™ ya selire

Uburyo™ ni ikirango cya elegisi ya selile yakozwe na dow. Ubwo bugari bukomoka kuri selile, polymer karemano iboneka mu nkike za serile. Chimie yububiko ™ ikubiyemo guhindura selile binyuze mubitekerezo byanyuma. Ubwoko bwibanze bwa uburyo ™ burimo hydroxypropyl methylcellse (HPMC) na methycellUlose (MC), buri kimwe gifite imiterere yimiti. Dore incamake rusange ya chimie yububiko ™:

1. HydroxyPropyl Methylcellse (HPMC):

• Imiterere:
  • HPMC ni ugukemura amazi ether hamwe nabasimbuye babiri basimbuye: hydroxyPropyl (hp) na methyl (m).
  • Amatsinda ya hydroxyPropyl atangiza imikorere ya hydrophilic, kuzamura amazi yoroheje.
  • Amatsinda ya methyl atanga umusanzu muri rusange kandi akagira ingaruka kumitungo ya polymer.
• Igisubizo cya Guhuza:
  • HPMC ikorwa binyuze muburyo bwa selile hamwe na propaylene oxide (kumatsinda ya hydroxyPropyl) na methyl chloride (kumatsinda ya methyl).
  • Ibisabwa kugenzurwa neza kugirango ugere ku rwego rwo gusimbuza (DS) kumatsinda yombi ya hydroxyPropy na methyl.
• Umutungo:
  • HPMC yerekana amazi meza cyane, imitungo yo gukora firime, kandi irashobora gutanga irekurwa muri farumasi.
  • Urwego rwo gusimburwa rugira ingaruka ku basura Polymer, imurikagurisha ry'amazi, n'ibindi bintu.

2. Methylcellse (MC):

• Imiterere:
  • MC ni selile ether hamwe na methyl abasimbuye methyl.
  • Irasa na HPMC ariko ibuze amatsinda ya hydroxyPropyle.
• Igisubizo cya Guhuza:
  • MC ikorwa no gukora selile hamwe na methyl chloride.
  • Ibisabwa kugenzurwa kugirango ugere kurwego rwifuzwa.
• Umutungo:
  • MC ni ugushonga amazi kandi ifite ibyifuzo muri farumasi, kubaka, ninganda zibiribwa.
  • Ikoreshwa nka binder, ubugome, na stilizer.

3. Ibintu bisanzwe:

• Amazi yonyine: HPMC na MC byombi birashonje mumazi akonje, bikora ibisubizo bisobanutse.
• Gushiraho filime: Barashobora gukora firime zoroshye kandi zihuriye kandi zituma zingirakamaro muburyo butandukanye.
• Kwinginga: Uburyo ™ ™ selire ya selile ikora nkibibyimba byiza, bigira ingaruka kuri viscosiya.

4. Porogaramu:

• Farumasiti: ikoreshwa mubyoroheje, bihuza, no kugenzurwa-kurekura.
• Kubaka: Akoreshwa mu misozi, tile afatika, n'ibindi bikoresho byo kubaka.
• Ibiryo: Byakoreshejwe nkabariba na stabilizers mubicuruzwa.
• Kwitaho kugiti cyawe: Biboneka muri kwisiga, shampoos, nibindi bintu byita kugiti cyawe.

Chimie yuburyo bwa methice ™ TELUESE Atuma bigira ibikoresho bifatika hamwe nibisabwa bitandukanye, bitanga kugenzura imitungo yimiterere, kugumana amazi, nibindi biranga ibintu bitandukanye. Ibintu byihariye birashobora gutunganizwa no guhindura urwego rwo gusimburwa nibindi bipimo.
