Iimpawu zemveliso

Polyethylene glycol 20000 - iipropati

Le mveliso yinto emhlophe emhlophe. Unyibilika emanzini, unyibilike kwezinye izinyibilikisi eziphilayo. Isisombululo sayo sines viscosity ephezulu kuxinzelelo oluphantsi, kwaye ingaqwalaselwa nge-calendering, extrusion kunye nokuphosa. Yintlaka ye-thermoplastic enokuhambelana okuhle nezinye iivenkile. Iyaxhathisa kukhukuliseko lwebacteria kwaye ine-hygroscopicity ebuthathaka emoyeni.

I-Polyethylene glycol 20000-Imigangatho

Le mveliso ngumxube we-ethylene oxide kunye namanzi. Ifomula yefomula ibonakaliswe njengeHo (CH2CH2O) NH, apho n imele inani eliphakathi lamaqela e-oxyvinyl.

Polyethylene glycol 20000 - indlela yokulungiselela

I-Ethylene oxide iyenziwe ipolymer kunye ne-aluminium isopropoxide njenge-catalyst.

Polyethylene glycol 20000 - iipropati

Le mveliso ayinambala okanye i-liquid viscous liquid, okanye i-wax e-translucent soft; ivumba kancinci.
Le mveliso inyibilika emanzini okanye kwi-ethanol, kodwa hayi kwi-ether

Polyethylene glycol 20000 - ukusetyenziswa

I-Poly (i-ethylene oxide) yintlaka ye-molecular homopolymer ephezulu eyenziwe ngokuvula i-polymerization ye-ethylene oxide nge-catalysis engafaniyo. Eyokuqala ibizwa ngokuba yi-polyethylene glycol kwaye eyokugqibela yi-polyoxyethylene. I-Polyethylene oxide (PEO) ineempawu zokuthambisa, ukuqina, ukukhutshwa kancinci, ukuthambisa, ukusasaza, ukugcinwa kunye nokugcinwa kwamanzi. Ilungele amayeza, isichumisi semichiza, ukwenza iphepha, iiseramikhi, iisepha, izithambiso, unyango lobushushu, unyango lwamanzi, ukhuseleko lomlilo, ukuxhaphaza ioyile kunye namanye amashishini. Imveliso ayiyityhefu kwaye ayicaphukisi, kwaye ayizukuhlala, ifake okanye izalise izinto eziguqukayo kwinkqubo yokuvelisa imveliso. Njengephepha elenza iphepha, linokunyusa izinga lokugcinwa kwamacwecwe kunye nefayibha entle, ngakumbi efanelekileyo ekusasazeni ifayibha ende kunye nokunciphisa ixesha lokubetha.
