Ethers ya Cellulose - incamake

Etherbyerekana umuryango utandukanye wamazi ya elegitoronike ya polymers akomoka kuri selile, polyisikaride karemano iboneka murukuta rw'utugingo ngengabuzima. Ibikomokaho bikozwe hifashishijwe imiti ihindura selile, bivamo ibicuruzwa bitandukanye bifite imiterere yihariye. Ether ya selulose isanga ikoreshwa cyane mubikorwa bitandukanye bitewe nuburyo budasanzwe bwo gukemura amazi, imiterere ya rheologiya, hamwe nubushobozi bwo gukora film. Dore incamake ya ethers ya selile:

1. Ubwoko bwa Cellulose Ethers:

• Hydroxyethyl Cellulose (HEC):
  • Porogaramu:
    • Irangi hamwe nigitambara (umubyimba woguhindura na rheologiya uhindura).
    • Ibicuruzwa byawe bwite (shampo, amavuta yo kwisiga, amavuta).
    • Ibikoresho byubwubatsi (minisiteri, ibifatika).
• Hydroxypropyl Methylcellulose (HPMC):
  • Porogaramu:
    • Ubwubatsi (minisiteri, ibifatika, ibifuniko).
    • Imiti (binder, firime yahoze muri tableti).
    • Ibicuruzwa byawe bwite (kubyimbye, stabilisateur).
• Methyl Hydroxyethyl Cellulose (MHEC):
  • Porogaramu:
    • Ubwubatsi (kubika amazi muri minisiteri, ibifatika).
    • Ipitingi (moderi ihindura amarangi).
• Carboxymethyl Cellulose (CMC):
  • Porogaramu:
    • Inganda zibiribwa (umubyimba, umukozi uhoraho).
    • Imiti ya farumasi (ihuza ibinini).
    • Ibicuruzwa byawe bwite (kubyimbye, stabilisateur).
• Ethyl Cellulose (EC):
  • Porogaramu:
    • Imiti yimiti (igenzurwa-irekura).
    • Impuzu zidasanzwe hamwe na wino (film yahoze).
• Sodium Carboxymethyl Cellulose (NaCMC cyangwa SCMC):
  • Porogaramu:
    • Inganda zibiribwa (umubyimba, umukozi uhoraho).
    • Imiti ya farumasi (ihuza ibinini).
    • Gucukura amavuta (viscosifier mumazi yo gucukura).
• Hydroxypropylcellulose (HPC):
  • Porogaramu:
    • Kwambara (kubyimbye, firime yambere).
    • Imiti yimiti (binder, disintegrant, igenzurwa-kurekura).
• Microcrystalline Cellulose (MCC):
  • Porogaramu:
    • Imiti yimiti (binder, disintegrant mubinini).

2. Ibintu rusange:

• Amazi meza: Ethers nyinshi ya selile irashobora gushonga mumazi, itanga kwinjiza byoroshye muri sisitemu y'amazi.
• Kubyimba: Ethers ya selile ikora nkibibyibushye bikora muburyo butandukanye, byongera ubwiza.
• Imiterere ya Firime: Ethers zimwe na zimwe za selile zifite imiterere-yimikorere ya firime, zitanga umusanzu hamwe na firime.
• Gutuza: Bahindura emulisiyo no guhagarikwa, birinda gutandukana kwicyiciro.
• Gufatanya: Mubikorwa byubwubatsi, selile ya selile itezimbere no gukora.

3. Gusaba Inganda:

• Inganda zubaka: Zikoreshwa muri minisiteri, ibifata, grout, hamwe na coatings kugirango uzamure imikorere.
• Imiti ya farumasi: Akazi nka binders, disintegrants, abakora firime, hamwe nabashinzwe kugenzura-gusohora.
• Inganda zibiribwa: Zikoreshwa mubyimbye no gutuza mubiribwa bitandukanye.
• Ibicuruzwa byawe bwite: Harimo kwisiga, shampo, n'amavuta yo kwisiga kugirango ubyibushye kandi uhamye.
• Kwambika amarangi: Kora nk'abahindura rheologiya hamwe nabashinzwe gukora firime mu marangi no gutwikira.

4. Gukora n amanota:

• Ethers ya selile ikorwa muguhindura selile binyuze muri reaction ya etherification.
• Ababikora batanga ibyiciro bitandukanye bya selile ya selile hamwe na viscosities zitandukanye hamwe nibintu bihuye nibisabwa byihariye.

5. Ibitekerezo byo gukoresha:

• Guhitamo neza ubwoko bwa selulose ether nicyiciro ningirakamaro ukurikije imikorere yifuzwa mubicuruzwa byanyuma.
• Ababikora batanga impapuro za tekiniki nubuyobozi bukoreshwa neza.

Muri make, ethers ya selile igira uruhare runini mubikorwa bitandukanye, bigira uruhare mubikorwa n'imikorere yibicuruzwa mubwubatsi, imiti, ibiryo, ubuvuzi bwihariye, hamwe ninganda. Guhitamo selile yihariye ya ether biterwa na progaramu igenewe hamwe nibintu byifuzwa byibicuruzwa byanyuma.
