Imininingwane yomkhiqizo

Imibuzo evame ukubuzwa

Amathegi womkhiqizo

Izicelo Main:Lo mkhiqizo awunabuthi, awucasuli futhi unomswakama omuhle wamanzi, ukuhambisana, ukuthambisa, ukunamathela nokuqina kokushisa. Ngakho-ke, uchungechunge lwe-PEG-300 lufanelekile ukulungiselela amaphilisi athambile. Inokuhambisana okubanzi nezinhlobonhlobo zamakhemikhali awuketshezi, ngakho-ke iyisixazululo esihle ne-solubilizer futhi isetshenziswa kakhulu kumalungiselelo oketshezi, njengesisombululo somlomo, amaconsi wamehlo, njll.

Ukupakisha Indlela:Isigubhu seplastiki esingu-50kg 

Impilo eshalofini: Iminyaka emithathu     

Ikhwalithi ejwayelekile: I-CP2015
Ukugcinwa nokuthuthwa: Lo mkhiqizo awunabuthi, ulibazisa welangabi, njengokuthunyelwa okujwayelekile kwamakhemikhali, okuvaliwe nokugcinwa endaweni eyomile.

Izicelo ze-Biomedical

I-polyethylene glycol yezokwelapha yaziwa nangokuthi i-polyethylene oxide (PEO). I-polyether yomugqa yatholwa ngokuvulwa kwendandatho ye-ethylene oxide. Izicelo eziyinhloko emkhakheni we-biomedical zimi kanje:
1. Isixazululo selensi yokuxhumana. I-viscosity yesisombululo se-polyethylene glycol e-aqueous iyazwela kusilinganiso se-shear futhi amabhaktheriya akulula ukukhula kwi-polyethylene glycol.
2. Isigcilikisha sokwenziwa. I-ethylene oxide ne-polymens condensation polymer. Ukuze kulungiswe i-matrix yokugcoba yezidakamizwa ezincibilika emanzini, ingasetshenziswa futhi njenge-solvent ye-acetylsalicylic acid, i-caffeine, i-nimodipine nezinye izidakamizwa ezingaxazululeki ukulungiselela umjovo.
3. Ukulethwa kwezidakamizwa kanye ne-enzyme carrier engenamandla. Lapho i-polyethylene glycol isixazululo samanzi sigqokwa engxenyeni engaphandle yephilisi, ukusakazeka kwesidakamizwa esisesiphilisi kungalawulwa ukwenza ngcono ukusebenza kahle.
4. Surface ukuguqulwa medical polymer izinto. Ukutholakala kwe-biocompatibility kwezinto zokwelapha ze-polymer ezithintana negazi kungathuthukiswa ngokufakwa kwezikhangiso, ukugcinwa kanye nokuxhunyelelwa kwe-amphiphilic copolymer equkethe i-polyethylene glycol ebusweni bezinto ze-polymer zezokwelapha.
5. Yenza ifilimu yokuvimbela inzalo i-alkanol.
6. Ukulungiswa kwe-hydrophilic anticoagulant polyurethane.
7. I-Polyethylene glycol 4000 iyi-laxative ye-osmotic, engakhuphula ingcindezi ye-osmotic, imunce amanzi, ithambise indle, yenyuse ivolumu, futhi ikhuthaze i-peristalsis yamathumbu kanye nokuzikhandla.
8. Ukulungisa amazinyo okufakelwa. I-Polyethylene glycol yayisetshenziswa njengengxenye yokulungiswa kwamazinyo okufakelwa ngenxa yezindawo zayo ezingezona ezinobuthi neze-gelling.
9. I-PEG 4000 ne-PEG 6000 zivame ukusetshenziselwa ukukhuthaza ukuhlangana kwamaseli noma i-protoplast fusion nokusiza izinto eziphilayo (isib. Imvubelo) ukumunca i-DNA ngesikhathi soguquko. Isikhonkwane singamunca amanzi esixazululweni, ngakho-ke siyasetshenziswa ukugxilisa isixazululo.
10. Ekuvivinyweni kokutadisha ama-molecule wamaprotheni, singalingisa indawo eminyene e-vivo ukuqinisekisa ithonya lokugcwala kwemvelo esakhiweni samaprotheni
