Iimpawu zemveliso

I-ethylene glycol (i-ethylene glycol) ikwabizwa ngokuba yi "glycol", "1,2-ethylene glycol", efinyezwe njenge-EG. Ifomula yamachiza (CH2OH) 2 sesona silula. I-Ethylene glycol ayinambala, ayinavumba kwaye ineencindi ezimnandi, inetyhefu kwizilwanyana, kwaye idosi ebulalayo yomntu imalunga ne-1.6 g / kg. I-Ethylene glycol inokunyibilika ngamanzi kunye ne-acetone, kodwa ukunyibilika kwayo kwi-ether kuncinci. Isetyenziswa njenge-solvent, iarhente yokubambisa kunye nezinto ezingafunekiyo zepolyester eyenziweyo.

IPropathi yomzimba

Inkangeleko kunye neepropathi: ulwelo olungenambala, uswiti kunye viscous

I-viscisiti: Inkunkuma.s (16 ℃)

Ukunyibilika: I-miscible ngamanzi / i-ethanol / i-acetone / i-glyceropyridine acetate, inyibilika kancinci kwi-diethyl ether, ingenakunyibilika kwi-petroleum hydrocarbons kunye neoyile, inokunyibilikisa izinto ezingaphiliyo ezifana ne-calcium chloride / zinc chloride / sodium chloride / potassium carbonate / potassium chloride / potassium iodide / potassium hydroxide .

Uxinzelelo lobume: 46.49 mN / m (20 ℃)

Indawo yokuflasha: 418 ℃

Ubushushu bokutsha: 1180.26KJ / mol
Ngama-25 degrees Celsius, i-dielectric rhoqo i-37
Ukufunxa ukufuma kulula xa uxinzelelo luphezulu

Injongo

Isetyenziselwa ukwenza ipholiyesta, i-resin ye-polyester, iarhente yeplastikhi, iplastikhi, into eyenziwayo, ifayibha yokwenziwa, izinto zokuthambisa kunye neziqhushumbisi, kwaye isetyenziswa njenge-solvent yedayi, i-inki njalo njalo, iarhente yokubulala ubushushu yokulungiselela i-injini, iarhente yokuphelisa igesi, ukwenza i-resin, nayo inokusetyenziselwa i-Cellophane, ifayibha, ulusu, iarhente yokumanzisa ukunamathela. Inokuvelisa i-resin PET eyenziweyo, ifayibha yebanga le-PET yifayibha ye-polyester, ibakala lebhotile le-PET lisetyenziselwa ukwenza ibhotile yamanzi yezimbiwa, njl. Ukongeza ekusebenziseni njengearhente yokubulala ubushushu kwiimoto, ikwasetyenziselwa ukuhambisa amandla okupholisa kwimizi mveliso, ebizwa ngokuba sisiphathi kubanda. Kwangelo xesha, inokusetyenziselwa ukujija njengamanzi.
Iimveliso zothotho ze-ethylene glycol methyl ether zinamachiza anyibilikayo aphezulu asebenza ngokugqwesileyo, asetyenziswa njengezinyibilikisi kunye nezinyibilikisi zokushicilela i-inki, iiarhente zokucoca ezomashishini, ukutyabeka (ipeyinti yefayibha yeNitro, ivanishi, ipeyinti yephosilini), iipleyiti ezinxibe ubhedu, ushicilelo kunye nokudaya njl. inokusetyenziswa njengempahla eluhlaza yokuvelisa iimveliso zeekhemikhali ezinje ngee-pesticide intermediates, izixube zamayeza kunye nolwelo lokuqhekeza olwenziweyo; Ingasetyenziswa njenge-electrolyte yee-capacitors ze-electrolytic, iidayi zekhemikhali zokwenza imichiza, njl njl.
Xa i-ethylene glycol isetyenziswa njengesixhobo sokupholisa, kufuneka kuhlawulwe:
1. Indawo yayo ebandayo iyatshintsha notshintsho lwe-ethylene glycol kwisisombululo samanzi. Xa uxinzelelo lungaphantsi kwe-60%, uxinzelelo lwe-ethylene glycol kwisisombululo esinamandla siyanda kwaye indawo yokubanda iyancipha. Nangona kunjalo, emva koxinzelelo olungaphezulu kwe-60%, ngokunyuka kwe-ethylene glycol, indawo yayo ebandayo ibonisa imeko ephezulu, kunye ne-viscosity yayo iya kwanda ngokwanda koxinzelelo. Xa uxinzelelo lufikelela kuma-99.9%, indawo yalo ebandayo inyukela kwi -13.2 ℃, esisizathu esibalulekileyo sokuba ulwelo lwe-antifreeze fluid (umama wotywala we-antifreeze fluid) lungasetyenziswa ngokuthe ngqo, kwaye kufuneka litsale ingqalelo yabasebenzisi.
2. I-Ethylene glycol iqulethe amaqela e-hydroxyl. Ukuba isebenza kuma-80-90 degrees celsius ixesha elide, i-ethylene glycol iya kuxutywa kwi-ethanolic acid kuqala, emva koko kwi-oxalic acid, oko kukuthi, i-ethanolic acid (i-oxalic acid), enamaqela amabini e-carboxyl. I-oxalic acid kunye neemveliso zayo ziya kuchaphazela inkqubo ye-nervous central kuqala, emva koko intliziyo, kunye nezintso. Ukuba akukho nyango lululo, ukungenisa kakhulu i-ethylene glycol kuya kukhokelela ekufeni. I-Ethylene glycol succinic acid ibangela umhlwa kwizixhobo kwaye iyenze ivuze. Ke ngoko, kwisisombululo se-antifreeze esilungisiweyo, kufuneka kubekho izinto zokuthintela ukubola kwentsimbi kunye nealuminium kunye nokuveliswa kwesikali.
Ukupakisha, ukuGcina kunye nokuThutha
Ipakishwe kumgqomo wentsimbi we-GI, i-200Kg ngomgqomo. Ngexesha lokugcina, kufuneka litywinwe. Ukugcinwa kwexesha elide, kufuneka kutywinwe nge-nitrogen, ubungqina bomswakama, ubungqina bomlilo kunye ne-antifreeze. Ukugcinwa kunye nokuThuthwa ngokwemigaqo yeekhemikhali ngokubanzi.
