I-Polyethylene Glycol(PEG)

I-Polyethylene glycol, efushanisiwe ngokuthi 'PEG,' iyinhlanganisela yesisindo samangqamuzana ephezulu eyakhiwe ukuphelelwa amanzi emzimbeni kanye nokufiphala kwe-ethylene glycol. Ifomula yayo yamakhemikhali ingu-HOCH2(CH2OCH2)nCH2OH, lapho n ingaphezu kuka-4, enesisindo semolekyuli esimaphakathi esisuka ku-200 kuya ku-7000.

I-Polyethylene Glycol (PEG)

Inombolo ye-CAS: 25322-68-3
I-Molecular Formula: H(OCH₂CH₂)nOH
Isisindo se-Molecular: Iyahlukahluka kuye ngesisindo se-molecular (isb, i-PEG 200 - PEG 20000)

Uhlolojikelele Lomkhiqizo

I-Polyethylene Glycol (PEG) iyi-polymer eguquguqukayo, encibilika emanzini esetshenziswa kabanzi kwezemithi, izimonyo, ukucubungula ukudla, kanye nezicelo zezimboni. Itholakala ngezinhlobo eziningi zezisindo zamangqamuzana, kusukela oketshezini olune-viscosity ephansi ukuya kokuqinile okuncibilika kakhulu.

I-PEG ibaluleke kakhulu ngenxa yokuthambisa kwayo okuhle kakhulu, ukuncibilika, ukungabi nabuthi, kanye nokuzinza kwamakhemikhali , okuyenza ibe isithako esibalulekile ekwakhiweni okudinga ukugcinwa komswakama, ukuhlakazeka, nokuguqulwa kwendawo.

Izici Eziyinhloko Nezinzuzo

I -Wide Molecular Weight Range
Itholakala njenge-PEG 200, PEG 400, PEG 600, PEG 1000, PEG 4000, PEG 6000, njll.
Ukuncibilika Kwamanzi Okuhle Kakhulu
Incibilika kalula emanzini nasezincibilikiseni eziningi eziphilayo.
Ubuthi obuphansi kanye ne-Biocompatibility
Ifanele izicelo zemithi nezimonyo.
Izinto Zokuthambisa & Zokuthambisa
Ithuthukisa ukuthungwa nokusebenza ekwakhekeni.
Ukuzinza Kwekhemikhali
Kuzinzile ngaphansi kwamazinga okushisa nezimo ezihlukahlukene.

Izinhlelo zokusebenza

1. Imithi

Isetshenziswa njenge -solvent, i-ointment base, kanye nomthwali wezidakamizwa
Ithuthukisa ukunyibilika kwezidakamizwa kanye ne-bioavailability
Isetshenziswa kuma-laxatives kanye nokwakhiwa kwethebhulethi

2. Izimonyo Nokunakekelwa Komuntu Siqu

Isebenza njenge -moisturizer, i-emulsifier, ne-thickener
Kutholakala kokhilimu, izinto zokugcoba, ama-shampoos, kanye nomuthi wokuxubha

3. Izicelo zezimboni

Amafutha kanye nama-ejenti wokukhulula
Ukuqedwa kwendwangu kanye nokucubungula
Izithasiselo zenjoloba nezepulasitiki

4. Imboni Yokudla

Isetshenziswa njengesengezo sokudla (emabangeni avunyelwe)
Isebenza njenge-ejenti yokugqoka kanye ne-stabilizer

Ukupakisha & Isitoreji

Izinketho zokupakisha:

25 kg izikhwama / izigubhu
200 kg izigubhu (amabanga liquid)
Amathangi e-IBC ayatholakala
Ukupakishwa okwenziwe ngokwezifiso kuyasekelwa

Imibandela Yesitoreji:

Gcina endaweni epholile, eyomile, futhi enomoya omuhle
Gcina isiqukathi sivalwe ngokuqinile
Gwema ukuchayeka elangeni eliqondile kanye nomswakama

Imibuzo Evame Ukubuzwa (FAQs)

1. Uyini umehluko phakathi kwe-PEG 400 ne-PEG 6000?

I-PEG 400 iwuketshezi olunesisindo esiphansi samangqamuzana , kuyilapho i-PEG 6000 iqinile enesisindo samangqamuzana esiphezulu , enikeza i-viscosity ephakeme kanye nezakhiwo ezihlukile zohlelo lokusebenza.

2. Ingabe i-Polyethylene Glycol iphephile ukusetshenziswa kwezemithi?

Yebo, i-PEG yezinga lezemithi isetshenziswa kabanzi ngenxa yobuthi bayo obuphansi nokuvumelana okuhle kwe-biocompatibility , inqobo nje uma ihlangabezana nezindinganiso zokulawula.
