I-polyethylene glycol Peg 200 CAS NO.25322-68-3
Incazelo Yemikhiqizo
- I-PEG isifinyezo segama lesiNgisi elithi polyethylene glycol. I-PEG 200 ayinabo ubuthi, ayicunuli, inokuncibilika kahle kwamanzi, futhi inokuhambisana okuhle nezakhi eziningi eziphilayo. Zinokugcotshwa okuhle kakhulu, ukugcinwa komswakama, ukuhlakazeka, okunamathelayo, ama-antistatic agents kanye nezithambisa, njll., futhi zisetshenziselwa izimonyo, imithi, imicu yamakhemikhali, irabha, amapulasitiki, iphepha, upende, i-electroplating, izibulala-zinambuzane, ukucubungula insimbi nokucubungula ukudla, njll. Kunezinhlelo zokusebenza ezibanzi kakhulu embonini.
- I-PEG-200 ingasetshenziswa njengendlela yokuhlanganisa izinto eziphilayo kanye nesithwali sokushisa esinezidingo eziphezulu. Ingasetshenziswa njenge-humectant, i-inorganic salt solubilizer, kanye nesilawuli se-viscosity embonini yamakhemikhali yansuku zonke; ingasetshenziswa njenge-softener kanye ne-ejenti ye-antistatic embonini yendwangu. ; Isetshenziswa njenge-ejenti yokumanzisa ezimbonini zokwenza amaphepha nezibulala-zinambuzane. Njengensimbi yokucubungula isikhunta ejenti, umdwebo wensimbi, isitembu noma ukwakha i-lubricant kanye noketshezi lokusika, ukugaya okupholisa i-ejenti yokupholisha, i-ejenti yokushisela, njll.; esetshenziswa njengesithambisi embonini yephepha, njll., futhi isetshenziswa futhi njengesinamathelisi esincibilikayo esishisayo ukwandisa ikhono lokumanzisa kabusha Ngokushesha. I-PEG-200 ayinabo ubuthi, ayishi, futhi igcinwa futhi ithuthwe njengamakhemikhali avamile. Gcina endaweni eyomile futhi engenawo umoya.

Isicelo
- Imikhiqizo yochungechunge lwe-Polyethylene glycol ingasetshenziswa kwezokwelapha.I-polyethylene glycol enesisindo esiphansi samangqamuzana ingasetshenziswa njenge-solvent, i-cosolvent, i-disperant, i-O/W yohlobo lwe-emulsifier ne-stabilizer, esetshenziselwa ukwenza ukumiswa kukasimende, ama-emulsions, imijovo, njll. futhi ibuye isetshenziswe njengesisekelo samafutha esincibilikayo emanzini kanye nesisekelo se-Suppository, i-waxy eqinile i-polyethylene glycol enesisindo esihlobene samangqamuzana ngokuvamile isetshenziselwa ukwandisa i-viscosity kanye nokuqina kwe-low molecular weight liquid PEG, kanye nokunxephezela ezinye izidakamizwa; ngezidakamizwa ezingancibiliki kalula emanzini, lo mkhiqizo ungasetshenziswa njengesithwali esiqinile sokuhlakazeka , Ukuze kuzuzwe inhloso yokuhlakazeka okuqinile.
- Imikhiqizo yochungechunge lwe-polyethylene glycol ingasetshenziswa njengezinto ezingavuthiwe zama-ester surfactants.
- Ingasetshenziswa njengesisetshenziswa se-organic synthesis kanye nesithwali sokushisa esinezidingo eziphezulu. Ingasetshenziswa njenge-humectant, i-inorganic salt solubilizer kanye nesilawuli se-viscosity embonini yamakhemikhali yansuku zonke; njenge-ejenti yokuthambisa kanye ne-antistatic embonini yendwangu; Isetshenziswa njenge-ejenti yokumanzisa ezimbonini zokwenza amaphepha nezibulala-zinambuzane.
