Indawo yokubilisa ye-Ethylene Glycol kunye nohlalutyo lwepropati yeekhemikhali
Kwishishini lemichiza, i-ethylene glycol (i-Ethylene Glycol) yinto ebalulekileyo yeekhemikhali ekrwada esetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana ne-antifreeze kunye nokuveliswa kwe-resin. Ukuqonda iimpawu ze-physicochemical ze-Ethylene Glycol, ngokukodwa indawo yayo yokubilisa, ibalulekile ekusebenziseni kwayo kwishishini. Kule nqaku, indawo yokubilisa ye-ethylene glycol kunye nefuthe layo elichaphazelekayo liya kuxutyushwa ngokubanzi.
Iipropati eziSisiseko ze-Ethylene Glycol kunye neNdawo yokuBilisa
I-Ethylene glycol lulwelo olungenambala, olungenavumba, olunevumba elimnandi kunye nefomula yeekhemikhali C₂H₆O₂. Njenge-diol, i-ethylene glycol ine-hygroscopicity eyomeleleyo kunye neempawu ezintle zokunyibilika. Indawo yokubila ye-ethylene glycol yi-197.3°C. Eli xabiso, elilinganiswa kuxinzelelo lwe-atmospheric, libonisa ukuzinza kwesakhiwo sayo se-molecular kunye namandla e-intermolecular hydrogen bonds.
Izinto ezichaphazela indawo yokubilisa kunye nokubaluleka kwayo kwezoshishino
Indawo yokubilisa ye-ethylene glycol iphenjelelwa yizinto ezininzi. Ukudibanisa i-Hydrogen kwisakhiwo se-molecular kunempembelelo ebalulekileyo kwindawo yokubilisa. I-molecule ye-ethylene glycol iqulethe amaqela amabini e-hydroxyl (-OH), adityaniswe ngamabhondi e-hydrogen, okwenza i-intermolecular forces ye-ethylene glycol ibe yomelele kwaye ikhokelela kwindawo yokubilisa ephezulu. Ubunzima bemolekyuli ye-ethylene glycol nayo ichaphazela indawo yayo yokubilisa, kunye neentsimbi ezinkulu zemolekyuli ezifuna amandla angakumbi okuba ngumphunga.
Kwizicelo zoshishino, indawo yokubilisa ye-ethylene glycol inempembelelo enkulu ekusebenzeni kwayo njenge-solvent, i-coolant kunye nezinye iimveliso. Ngokomzekelo, indawo ephezulu yokubilisa yenza i-glycol izinzile kwaye iyancipha kwiqondo lokushisa eliphezulu, ngaloo ndlela iqinisekisa ukusebenza kwayo kwizinto ezipholileyo kunye ne-antifreeze.
Izilumkiso xa kusetyenziswa
Xa usebenzisa i-ethylene glycol, ingqalelo kufuneka ihlawulwe ekusebenzisaneni kwendawo yokubilisa kunye nezinye izinto. Ngokomzekelo, kwii-composites okanye izisombululo ezixubileyo, ezinye izinto zinokuchaphazela indawo yokubilisa ye-ethylene glycol kwaye ngoko ke iipropati zokugqibela zemveliso. Ulwazi lwendawo yokubilisa ye-ethylene glycol lunokunceda ukwandisa iinkqubo zemveliso yemizi-mveliso, njengokulawula ubushushu ngexesha le-distillation kunye nokugxila.
Isishwankathelo, ukuqonda indawo yokubilisa ye-ethylene glycol kubalulekile kwisicelo sayo soshishino. Ngokuqonda le propati yomzimba ye-ethylene glycol, ukusebenza kwayo kwimveliso kunye nokusetyenziswa kunokulawulwa ngcono ukuphucula umgangatho kunye nokuzinza kwemveliso.
