3-Dimethylaminopropylamine / Dmapa
Ingcaciso yeMveliso
Olona setyenziso luphambili lwe-ethylene glycol luyi-arhente yokunqanda ukukhenkceza kwindawo yokupholisa umzekelo, iimoto kunye neenkqubo zokupholisa umoya ezibeka i-chiller okanye iziphatho zomoya ngaphandle okanye kufuneka ziphole ngaphantsi kweqondo lomkhenkce lamanzi. Kwiinkqubo zokufudumeza kwe-geothermal / ukupholisa, i-ethylene glycol lulwelo oluhambisa ubushushu ngokusetyenziswa kwempompo yobushushu be-geothermal. I-ethylene glycol ifumana amandla kumthombo (ichibi, ulwandle, amanzi kakuhle) okanye ichitha ubushushu kwi-sink, kuxhomekeke ekubeni inkqubo isetyenziselwa ukufudumeza okanye ukupholisa.
I-ethylene glycol ecocekileyo inomthamo othile wokushisa malunga nesiqingatha samanzi. Ke, ngelixa ubonelela ngokhuseleko lomkhenkce kunye nenqanaba lokubilisa elongeziweyo, i-ethylene glycol yehlisa umthamo othile wobushushu bemixube yamanzi xa kuthelekiswa namanzi acocekileyo. Umxube we-1:1 ngobunzima unomthamo othile wobushushu obumalunga ne-3140 J/(kg·°C) (0.75 BTU/(lb·°F)), iikota ezintathu zamanzi acocekileyo, ngaloo ndlela ifuna amazinga okuhamba okunyuka ngokufanayo- inkqubo uthelekiso namanzi.

Isicelo
| Ingasetyenziswa ngokubanzi kwizinto zokuthambisa, iidayi, i-ion exchange resins, i-oyile, ii-fungicides, izongezo ze-galvanizing ezingena-cyanide, i-fiber kunye ne-leather treatment agents, ii-epoxy resin zokunyanga ii-agents, iimfuno zemihla ngemihla, i-polyurethane foam catalysts kunye nezinye iinkalo. . |
Umxube we-ethylene glycol ngamanzi ubonelela ngeenzuzo ezongezelelweyo kwizisombululo zokupholisa kunye ne-antifreeze, ezifana nokuthintela ukubola kunye nokuthotywa kwe-asidi, kunye nokuthintela ukukhula kweentsholongwane ezininzi kunye ne-fungi. i-glycol igxininise, iikhompawundi, imixube, okanye izisombululo.
Kwishishini leplastiki, i-ethylene glycol yinto ephambili ebalulekileyo kwi-polyester fibers kunye ne-resins. I-Polyethylene terephthalate, esetyenziselwa ukwenza iibhotile zeplastiki kwiziphuzo ezithambileyo, zilungiswe kwi-ethylene glycol.
Inzuzo
Umgangatho wemveliso, ubungakanani obaneleyo, unikezelo olusebenzayo, umgangatho ophezulu wenkonzo Inenzuzo ngaphezu kwe-amine efanayo, i-ethanolamine, ekubeni i-concentration ephezulu ingasetyenziselwa ukubola okufanayo. Oku kuvumela abasulungeki ukuba bakhuhle ihydrogen sulfide ngesantya esisezantsi se-amine esijikelezayo sisebenzisa amandla angaphantsi ngokubanzi.
