Athini amabakala oXwebhu lwe-hypromellose?

I-Hypromellose, ekwabizwa ngokuba yi-hydroxypropyl methylcelcelcelse (i-HPMC), yipolymer ethathwe kwi-sellulose. Ngenxa yeepropathi zayo zokwahluka kwabantu, iqhele ukusetyenziswa kwimizi-mveliso eyahlukeneyo, kubandakanya amayeza, ukutya kunye ne-cosmetics. Ipropathi ebalulekileyo yeHypromellose i-viscofity yayo, eyahluka ngokuxhomekeke kwibakala okanye uhlobo lwe-hypromellose esetyenzisiweyo.

I-Hypromellose yamabakala ee-viscosity zihlala zihlelwa ngokobunzima bemolekyuli kunye nenqanaba lokufakwa endaweni. Ubunzima be-molecround buchaphazela ubude be-polymer ubude, ngelixa isidanga sokufaka sibhekisa kwinqanaba le-hydroxypropy kunye ne-methyl amaqela athatyathwe kwi-selsulose putbone.

Nazi amabakala athile okufana kakhulu kwe-hypromellose kunye neepropathi zabo:

1. Ibakala eliphantsi lokubonisa:

Iimpawu: ubunzima obuphantsi kwemolekyuli, imixokelelwane yePolymer.
Izicelo: La manqanaba asetyenziswa rhoqo njengezibonda kwifomu yecwecwe apho uVelosity osezantsi aqokelele ukuhamba okungcono kunye nokunyanzelwa.

I-2. Ibanga le-Viscosity:

Iipropathi: Ubunzima bemolekyuli ephakathi, ilungelelene phakathi kwe-viscosity kunye nokuluka.
Izicelo: Isetyenziswe ngokubanzi kwiindawo zamachiza njengemigangatho yeMatrix kwiNkqubo yokuZiswa kweZiyoli, kunye nomzi-mveliso wokutya wokutsalwa kunye nokugcwala.

3. Ibakala le-Vicofity:

Iimpawu: ubunzima obuphezulu bemolekyuli, amakhonkco amade ePolymer.
Isicelo: isetyenziswa ngokuqhelekileyo kwiNkqubo yokuKhulula kunye neZisombululo ze-Ophthalmic. Babonelela ngamandla aphuculweyo ne-vissity.

4. Inqanaba lobugcisa:

Iipropathi: Iipropathi zesiko sezicelo ezithile.
Izicelo: Amabakala esiko anokuphuhliswa ukuze afezekise iimfuno ezithile zamashishini ahlukeneyo njengokwenziwa kwee-opshalmic, izicelo eziphezulu kunye nokukhutshwa kweziyobisi.

Kufanelekile ukuba ukufumanisa ukuba uVeksisity uhlala ulinganiswa kwiiyunithi ze-punipoise (CP) okanye imizuzwana ye-millipascal (Mpas). Ibakala elithile lohlobo oluthile lokukhetha isicelo lixhomekeke kwiimpawu zentsebenzo ezinqwenelekayo, ezinjengeprofayili yokukhupha kwifomu yokukhupha okanye ukuthungwa kwiimveliso zokutya.

Xa ukhetha ibakala le-hypromellose, abavelisi baqwalasele izinto ezinje ngesicelo esichongiweyo, sifunekile ukuba sifuneke, kunye nokuhambelana nezinye izithako. Ukongeza, imigangatho yolawulo kunye neemfuno ezisebenzayo zinokuphembelela ukukhetha i-hypromellose kwifom yeziyobisi kunye nokutya.

Njengayo nayiphi na into, kubalulekile ukuba ulandele izikhokelo zeshishini kunye neenkcazo xa usebenzisa i-hypromellose ekuqinisekisweni ukuqinisekisa umgangatho wemveliso kunye nokuthobela imigangatho efanelekileyo.
