Cellulose Ethers-HPMC/CMC/HEC/MC/EC

aan sahamino furahaethers cellulose: HPMC (Hydroxypropyl Methylcellulose), CMC (Carboxymethyl Cellulose), HEC (Hydroxyethyl Cellulose), MC (Methyl Cellulose), iyo EC (Ethyl Cellulose).

1. Hydroxypropyl Methylcellulose (HPMC):
   • Guryaha:
     • Solubility: Biyo-milmay.
     • Shaqaynta: Waxay u shaqaysaa sidii dhumuc, xidhe, filim-hore, iyo wakiilka biyaha haynta.
     • Codsiyada: Qalabka dhismaha (madaxyada, xabagta tile), daawooyinka (dahaadhka kiniinka, hababka la xakameeyey), iyo alaabta daryeelka shakhsi ahaaneed.
2. Carboxymethyl Cellulose (CMC):
   • Guryaha:
     • Solubility: Biyo-milmay.
     • Shaqaynta: Waxay u shaqeysaa sidii dhumuc, dejiye, iyo wakiilka biyaha haynta.
     • Codsiyada: Warshadaha cuntada (sida dhumuc iyo xasiliye ahaan), dawooyinka, dunta, iyo alaabta daryeelka shakhsi ahaaneed.
3. Hydroxyethyl Cellulose (HEC):
   • Guryaha:
     • Solubility: Biyo-milmay.
     • Shaqeynta: Waxay u shaqeysaa sida dhumuclaha, xiraha, iyo wakiilka biyaha haynta.
     • Codsiyada: Rinjiyeynta iyo dahaarka, alaabta daryeelka shakhsi ahaaneed (shamboos, looshin), iyo qalabka dhismaha.
4. Methyl Cellulose (MC):
   • Guryaha:
     • Solubility: Biyo-milmay.
     • Shaqeynta: Waxay u shaqeysaa sidii dhumuc, xire, iyo filim-hore.
     • Codsiyada: Warshadaha cuntada, daawooyinka, iyo qalabka dhismaha.
5. Ethyl Cellulose (EC):
   • Guryaha:
     • Solubility: Aan ku milmin biyaha (ku milmay dareerayaasha organic).
     • Waxqabadka: Waxaa loo isticmaalaa sidii filim-hore iyo walxo daahan.
     • Codsiyada: Daawooyinka (dahaarka kiniiniyada), dahaarka loogu talagalay qaababka siidaynta la kantaroolo.

Tilmaamaha Guud:

• Biyuhu milmayn: HPMC, CMC, HEC, iyo MC waa biyo-milmi kara, halka EC caadi ahaan aan lagu milmi karin biyaha.
• Dhumucda: Dhammaan kuwan ethers cellulose waxay soo bandhigaan sifooyin dhumuc, ka qayb qaadashada xakamaynta viscosity ee codsiyada kala duwan.
• Sameynta Filimka: Dhowr, oo ay ku jiraan HPMC, MC, iyo EC, ayaa samayn kara filimaan, iyaga oo ka dhigaya kuwo waxtar u leh daaha iyo codsiyada daawooyinka.
• Biodegradability: Guud ahaan, ethers cellulose waa biodegradable, oo la jaan qaadaya dhaqamada deegaanka u saaxiibka ah.

Eter kasta oo cellulose ah wuxuu leeyahay sifooyin gaar ah oo ka dhigaya mid ku habboon codsiyada gaarka ah. Doorashada iyaga ka mid ah waxay ku xiran tahay arrimo ay ka mid yihiin shaqeynta la doonayo, shuruudaha milanka, iyo warshadaha/arjiga loogu talagalay. Waa muhiim in la tixgeliyo arrimahan oo lagala tashado tilmaamo farsamo marka la dooranayo ethers cellulose qaab gaar ah ama kiis la isticmaalo.
