3-Dimethylaminopropylamine / Dmapa
Product Description
Kushandiswa kukuru kwe ethylene glycol kunenge kwakaita seantifreeze agent muinotonhodza semuenzaniso, mota nema air-conditioning masisitimu ayo anoisa chiller kana ma air handles kunze kana anofanira kutonhodza pasi pechando chemvura. Mune geothermal heat / cooling systems, ethylene glycol ndiyo mvura inotakura kupisa kuburikidza nekushandiswa kwepombi inopisa inopisa. Iyo ethylene glycol inowana simba kubva kutsime (dziva, gungwa, tsime remvura) kana kubvisa kupisa kune sink, zvichienderana nekuti iyo system iri kushandiswa kupisa kana kutonhora.
Pure ethylene glycol ine chaiyo yekupisa inokwana hafu yemvura. Saka, nepo ichipa kudzivirira kwechando uye yakawedzera kufashaira poindi, ethylene glycol inodzikisira chaiyo yekupisa huwandu hwemvura yakasanganiswa inoenderana nemvura yakachena. A 1: 1 musanganiswa nehuremu ine chaiyo yekupisa inokwana 3140 J/(kg·°C) (0.75 BTU/(lb·°F)), zvikamu zvitatu muzvina zvemvura yakachena, nekudaro zvinoda kuwedzera kuyerera kwemazinga akafanana- hurongwa hwekuenzanisa nemvura.

*Maparameter acho ndeekungotaura chete. Kuti uwane rumwe ruzivo, tarisa COA
Application
| Inogona kushandiswa zvakanyanya muzvizoro mbishi zvinhu, madhayi, ion exchange resin, mafuta, fungicides, cyanide-isina galvanizing additives, fiber uye matehwe ekurapa, epoxy resin kurapa vamiririri, zvinodiwa zvezuva nezuva, polyurethane foam catalysts nezvimwe minda. . |
Musanganiswa we ethylene glycol nemvura unopa mamwe mabhenefiti kune zvinotonhodza uye antifreeze mhinduro, sekudzivirira ngura uye kuparara kweasidhi, pamwe nekudzivisa kukura kweutachiona huzhinji nefungi.Misanganiswa ye ethylene glycol nemvura dzimwe nguva inotaurwa zvisina kurongwa mumaindasitiri se. glycol inonangana, makomisheni, musanganiswa, kana mhinduro.
Muindasitiri yepurasitiki, ethylene glycol chinhu chakakosha chemberi kune polyester fiber uye resins. Polyethylene terephthalate, inoshandiswa kugadzira mabhodhoro epurasitiki ezvinwiwa zvinwiwa, inogadzirwa kubva ethylene glycol.
Advantage
Unhu hwechigadzirwa, huwandu hwakakwana, kuburitsa kunoshanda, mhando yepamusoro yebasa Iine bhenefiti pamusoro peamine yakafanana, ethanolamine, pakuti iyo yakakwira yekumisikidza inogona kushandiswa kune imwecheteyo ngura. Izvi zvinobvumira vanonatsa kukwesha hydrogen sulfide pamwero wakaderera wekutenderera amine nekushomeka kwesimba rose rekushandisa.
