Umthengisi we-PEG (iPolyethylene Glycol) eMzantsi Afrika
Uthotho lwepolymer olungeyo-ionic oluguquguqukayo — ukusuka kwi-liquid humectants (PEG-90) ukuya kwi-solid binders (PEG-4000) yokucoca imveliso eyenziweyo, amayeza, kunye nokusetyenziswa kwemizi-mveliso.

Yintoni iPolyethylene Glycol?
I-Polyethylene glycol (PEG) yi-polymer econdensation ye-ethylene oxide kunye namanzi, efumaneka kuluhlu oluqhubekayo lobunzima beemolekyuli - ukusuka kwiilwelo ezimfutshane (PEG-90, PEG-200, PEG-400) ukuya kwi-waxy solids ezinobunzima beemolekyuli eziphezulu (PEG-1500, PEG-4000). Inani elilandelayo yi-PEG libonisa ubunzima obuphakathi beemolekyuli kwiidaltons. Zonke iiklasi azina-ionic, azinyibiliki emanzini, kwaye aziguquguquki, kodwa imeko yazo yomzimba, i-viscosity, kunye nokufaneleka kokusetyenziswa kwazo kuyahluka ngokobunzima beemolekyuli.
Imisebenzi Yokuqulunqa NgokweBanga
IiPEG ezingamanzi eziphantsi kweMW (PEG-90 ukuya kwiPEG-600) zisetyenziswa njengezinto ezifunxayo, izinto ezinyibilikisayo, kunye nezinto ezidibanisayo kwiisepha zolwelo, iimveliso zokhathalelo lomntu, kunye nezisombululo zamayeza. IiPEG eziphakathi (PEG-1000, PEG-1500) zisebenza njengezinto ezithibazayo kunye neziguquli zokuhambelana. IiPEG eziqinileyo zeMW ephezulu (PEG-3350, PEG-4000) zizinto ezidibanisa iipilisi, iziseko zesuppository, kunye nezinto zokuthambisa kwimveliso yamayeza, kunye nezinto ezidibanisayo eziqinileyo kwiipilisi zokucoca umgubo ocinezelweyo kunye neebhloko zesepha yokuhlamba izitya.
Ukubonelela kunye noKhetho lweeBanga
Iikhemikhali zeTerracore zigcina amanqanaba e-PEG angamanzi naqinileyo ukusuka kwi-PEG-90 ukuya kwi-PEG-4000, kumanqanaba obuchwephesha, ezobuhle, kunye nezamayeza (i-USP). Sicebisa abenzi beefomyula malunga nokukhethwa kwamanqanaba kwimisebenzi ethile kwaye sinokubonelela ngobuninzi bomgangatho oxutyiweyo wophuhliso lwemveliso. Ukupakisha kufumaneka kwiidrama (amanqanaba angamanzi) kunye neengxowa ezingama-25 kg (amanqanaba aqinileyo).
