IHydroxypropyl Methylcellulose HPMC E3, E5, E6, E15, E50, E4M

IHydroxypropyl Methylcellulose (HPMC) yi-ether eselulosi enamabanga ahlukeneyo, echazwa ngoonobumba kunye namanani. La mabanga amele iinkcukacha ezahlukeneyo, kubandakanywa ukuhluka kobunzima be-molecular, umxholo we-hydroxypropyl, kunye ne-viscosity. Nalu ucazululo lwamabanga e-HPMC owakhankanyileyo:

1. I-HPMC E3:
   • Eli bakala linokuthi libhekiselele kwi-HPMC ene-viscosity ethile 2.4-3.6CPS. Inombolo ye-3 ibonisa i-viscosity ye-2% yesisombululo samanzi, kwaye amanani aphezulu abonisa ngokubanzi i-viscosity ephezulu.
2. HPMC E5:
   • Ngokufanayo ne-E3, i-HPMC E5 imele ibakala le-viscosity eyahlukileyo. Inombolo ye-5 ibonisa i-viscosity esondeleyo ye-4.0-6.0 CPS ye-2% yesisombululo samanzi.
3. I-HPMC E6:
   • HPMC E6 lelinye ibakala kunye iprofayile viscosity eyahlukileyo. Inombolo ye-6 ibonisa i-viscosity 4.8-7.2 CPS yesisombululo se-2%.
4. I-HPMC E15:
   • HPMC E15 kusenokwenzeka ukuba imele ibakala viscosity eliphezulu xa kuthelekiswa E3, E5, okanye E6. Inombolo ye-15 ibonisa i-viscosity 12.0-18.0CPS ye-2% yesisombululo se-aqueous, ebonisa ukuhambelana okukhulu.
5. HPMC E50:
   • I-HPMC E50 ibonisa ibakala eliphezulu le-viscosity, kunye nenombolo ye-50 emele i-viscosity 40.0-60.0 CPS yesisombululo se-2%. Eli bakala linokuba ne-viscosity ephezulu kakhulu xa kuthelekiswa ne-E3, E5, E6, okanye E15.
6. HPMC E4m:
   • "M" kwi-E4m ngokuqhelekileyo ibonisa i-viscosity ephakathi 3200-4800CPS. I-HPMC E4m imele ibakala elinenqanaba le-viscosity eliphakathi. Inokulungela izicelo ezifuna ibhalansi phakathi kolwelo kunye nobukhulu.

Xa ukhetha ibakala HPMC isicelo esithile, ingqalelo ziquka viscosity oyifunayo, ukunyibilika, kunye nezinye iimpawu zokusebenza. I-HPMC iqhele ukusetyenziswa kumashishini afana nokwakha, amayeza, izinto zokuthambisa, kunye nokutya.

Ekutyeni, i-HPMC ihlala isetyenziswa njengesongezo kwiimveliso ezingezizo ezobisi ukuphucula iipropathi ezifana nokugcinwa kwamanzi, ukusebenza, kunye nokuncamathela. Kumayeza kunye nezithambiso, i-HPMC isetyenziselwa ukwenza ifilimu kunye neempawu zokutyeba.

Kubalulekile ukubonisana nomvelisi okanye umboneleli ukuze ufumane iinkcukacha zobugcisa, kuquka iinkcukacha kunye nezicelo ezicetyiswayo kwibakala ngalinye le-HPMC. Abavelisi badla ngokubonelela ngamaxwebhu edatha yobugcisa kunye namaxwebhu emveliso ukukhokela abasebenzisi ekukhetheni elona bakala lifanelekileyo ngokweemfuno zabo ezithile.
