Ọdịdị molekụla ngwaahịa:
Diethylene glycol bụ mmiri mmiri na-enweghị isi, enweghị isi ma kwụsie ike.Ọ dịkwa ntakịrị viscous, anaghị emebi emebi na anaghị agbanwe agbanwe.N'ihi otu ether na mmanya na-aba n'anya, diethylene glycol na-egosipụta njirimara kemịkalụ nke ma ndị isi alcohol na ethers.Ebe isi ya dị elu nke ukwuu karịa nke ethylene glycol, ihe mgbaze ya dịkwa ukwuu.Diethylene glycol bụ mmiri, ethers, ala aliphatic alcohols, aldehydes na ketones ma bụrụ nke soluble na benzene, carbon tetrachloride, monobenzene, orthodichlorobenzene na toluene.Ọ na-agbaze ọtụtụ ihe eji esiji ákwà, resins, mmanụ, nitrocellulose na ọtụtụ ihe ndị dị ndụ.N'ihi ike mgbaze ya, obere mgbanwe na hygroscopicity, a na-eji ya na mmanu textiles, ịcha mmanụ, ncha nhicha akọrọ, ibi akwụkwọ ink, ink na-ese anwụrụ ọkụ, na ntụpọ osisi na-abụghị ọka.N'ime ụlọ ọrụ akwa, a na-eji diethylene glycol mee ihe dị ka ihe na-edozi ajị anụ, rayon na owu.Dị ka ihe mgbaze maka agba agba ọ na-eme ka onye enyemaka bara uru na ịcha akwa na ibipụta.Nnukwu hygroscopicity nke diethylene glycol na-eme ka ọ bụrụ ihe na-eme ka ọ dị nro maka ụtaba, akwụkwọ, sponge sịntetik, gluu na casein.Diethylene glycol bara uru karịsịa na akpịrị ịkpọ nkụ nke gas sitere n'okike.Ngwakọta nke diethylene glycol na monoethanolamine ga-ewepụ mmiri mmiri, hydrogen sulfide na carbon dioxide na gas.
Na ngwọta antifreeze maka usoro sprinkler, mmiri mkpuchi maka tankị gas, wdg (mmiri nwere 40% diethylene glycol freezes na -18 °; na 50% na -28 °);dị ka mmanụ mmanu na imecha ihe maka ajị anụ, nke kacha njọ, owu, rayon, na silk;dị ka ihe mgbaze maka vat agba;n'ihe mejupụtara corks, gluu, gelatin, casein, na pastes iji gbochie nkụ.
Diethylene glycol bụ mmiri na-enweghị isi, enweghị isi, mmiri doro anya.Ọ bụ miscible na mmiri ọ bụla ruru.Ọ nwere ọtụtụ ojiji ụlọ ọrụ.Ọ bụ akụkụ nke antifirizi, mmiri breeki, ihe ịchọ mma, ink, na ihe na-ehicha ihe, a na-ejikwa ya dị ka plasticizer.
Diethylene glycol (DEG) bụ ihe mgbaze na ihe a na-ejikarị eme ihe n'ọtụtụ ngwaahịa azụmahịa.A na-eji ya dị ka ihe na-eme ka mmiri na-ekpo ọkụ maka nhazi gas;dị ka mmanụ mmanu na imecha ihe maka textiles;ihe mejupụtara mmiri breeki, mmanu mmanu, usoro ihe mgbochi, akwụkwọ ahụaja na ihe ngwọta ihie;ihe mgbaze maka ibipụta inks na akwa akwa;ma jiri ya mee ihe dị ka etiti na mmepụta nke ụfọdụ resins, triethylene glycol, surfactants, na diethylene glycol esters na ethers.
Chemwin nwere ike inye nnukwu hydrocarbons na ihe mgbaze kemịkalụ maka ndị ahịa ụlọ ọrụ.Tupu nke ahụ, biko gụọ ozi ndị a bụ isi gbasara ịzụ ahịa na anyị:
1. Nchekwa
Nchekwa bụ ihe kacha anyị mkpa.Na mgbakwunye na ịnye ndị ahịa ozi gbasara iji ngwaahịa anyị dị mma na gburugburu ebe obibi, anyị na-agbakwa mbọ hụ na ihe egwu nchekwa nke ndị ọrụ na ndị ọrụ ngo belatara n'obere ezi uche na enwere ike.Ya mere, anyị na-achọ ka onye ahịa hụ na a na-ezute ụkpụrụ nbudata na nchekwa nchekwa kwesịrị ekwesị tupu nnyefe anyị (biko rụtụ aka na mgbakwunye HSSE na usoro izugbe na ọnọdụ ahịa n'okpuru).Ndị ọkachamara HSSE anyị nwere ike ịnye ntụzịaka na ụkpụrụ ndị a.
2. Usoro nnyefe
Ndị ahịa nwere ike ịtụ ma wepụta ngwaahịa sitere na chemwin, ma ọ bụ ha nwere ike nweta ngwaahịa sitere na ụlọ ọrụ nrụpụta anyị.Ụdị njem dịnụ gụnyere gwongworo, ụgbọ okporo ígwè ma ọ bụ ụgbọ njem multimodal (ọnọdụ dị iche na-emetụta).
