3-Dimethylaminopropylamine / Dmapa
Incazelo Yomkhiqizo
Ukusetshenziswa okuyinhloko kwe-ethylene glycol njenge-ejenti evimbela ukuqhwa endaweni epholile njengesibonelo, ezimotweni nezinhlelo zokupholisa umoya ezibeka i-chiller noma izibambi zomoya ngaphandle noma okumele ziphole ngaphansi kwezinga lokushisa elibandayo lamanzi. Ezinhlelweni zokushisisa/zokupholisa geothermal, i-ethylene glycol iwuketshezi oluthutha ukushisa ngokusebenzisa iphampu yokushisa kwe-geothermal. I-ethylene glycol ithola amandla emthonjeni (ichibi, ulwandle, umthombo wamanzi) noma ikhiphe ukushisa kusinki, kuye ngokuthi isistimu isetshenziselwa ukufudumeza noma ukupholisa.
I-ethylene glycol ehlanzekile inamandla athile okushisa cishe ingxenye eyodwa yamanzi. Ngakho-ke, ngenkathi ihlinzeka ngokuvikeleka kweqhwa kanye nephuzu elikhulayo lokubilisa, i-ethylene glycol yehlisa umthamo othile wokushisa wezingxube zamanzi ngokuhlobene namanzi ahlanzekile. Ingxube engu-1:1 ngesisindo inamandla athile okushisa angaba ngu-3140 J/(kg·°C) (0.75 BTU/(lb·°F)), izingxenye ezintathu kwezine zamanzi ahlanzekile, ngaleyo ndlela idinga ukukhuphuka kwamazinga okugeleza okufanayo- uhlelo ukuqhathanisa namanzi.

Isicelo
| Ingasetshenziswa kabanzi ezintweni zokusetshenziswa kwezimonyo, odayi, ama-ion exchange resins, amafutha, ama-fungicides, izithasiselo ezingenayo i-cyanide-free galvanizing, i-fiber kanye nama-ejenti wokwelapha wesikhumba, ama-epoxy resin elaphayo, izidingo zansuku zonke, ama-catalysts egwebu le-polyurethane neminye imikhakha. . |
Ingxube ye-ethylene glycol namanzi inikeza izinzuzo ezengeziwe ezixazululweni zokupholisa kanye ne-antifreeze, njengokuvimbela ukugqwala kanye nokuwohloka kwe-asidi, kanye nokuvimbela ukukhula kwamagciwane amaningi kanye nesikhunta.Izingxube ze-ethylene glycol namanzi ngezinye izikhathi zibizwa ngokungakahleleki embonini njenge. i-glycol igxila, izinhlanganisela, izingxube, noma izixazululo.
Embonini yepulasitiki, i-ethylene glycol iyisandulela esibalulekile semicu ye-polyester nama-resin. I-Polyethylene terephthalate, esetshenziselwa ukwenza amabhodlela epulasitiki eziphuzo ezithambile, ilungiswa kusuka ku-ethylene glycol.
Inzuzo
Izinga lomkhiqizo, inani elanele, ukulethwa okuphumelelayo, izinga eliphezulu lesevisi Inenzuzo kune-amine efanayo, i-ethanolamine, ngokuthi ukugxilisa okuphezulu kungase kusetshenziselwe amandla afanayo okugqwala. Lokhu kuvumela abacwengi ukuthi bakhuhle i-hydrogen sulfide ngenani eliphansi le-amine elijikelezayo ngokusetshenziswa kwamandla sekukonke.
