Tau Lelei a le Kamupani Gaosi D2000 CAS: 9046-10-0

fa'amatalaga pu'upu'u:

O le Amine-Terminated Polyether (D2000) o se vasega o polyolefin compounds e vaivai le ivi tua o le polyether, e fa'atapula'aina e vaega amine muamua po'o le lona lua. Talu ai ona o le filifili autu o le molecule o se vaivai le filifili polyether, ma o le hydrogen i le pito i tua o le polyether amine e sili atu lona malosi nai lo le hydrogen i le pito i tua o le hydroxyl group o le polyether, o lea la, e mafai e le polyether amine ona avea ma sui lelei mo le polyether i nisi o faiga o meafaitino, ma e mafai ona fa'aleleia atili ai le fa'atinoga o le fa'aogaina o meafaitino fou. E fa'aaogaina lautele le D2000 i mea e fa'apipi'i ai le polyurethane reactive injection, polyurea spraying, epoxy resin curing agents ma gasoline scavengers.

Meatotino Fa'akemikolo: O le Poly(propylene glycol) bis(2-aminopropyl ether) o se vai manino samasama vaivai pe leai foi se lanu i le vevela o le potu, faatasi ai ma le lelei o le maualalo o le viscosity, maualalo le mamafa o le ausa ma le maualuga o le anotusi amine autu, ma e mafai ona solo i totonu o solvents e pei o le ethanol, aliphatic hydrocarbons, aromatic hydrocarbons, esters, glycol ethers, ketones ma le vai.

Fa'aoga o le D2000

O le Poly(propylene glycol) bis(2-aminopropyl ether) e tete'e lelei i le alkali ma le vai ma e tete'e feololo i le 'āseta. O resins epoxy ua fa'amamāina i polyetheramines e iai uiga eletise lelei. O Polyetheramines e iai uiga tulaga ese ma e fa'aaogaina i toetoe lava o fa'aoga epoxy uma e pei o vali, mea e fa'apipi'i ai paluga, mea faufale, mea tu'ufa'atasi ma mea fa'apipi'i.
Sauniuniga: fa'aputuga o le Poly(propylene glycol) bis(2-aminopropyl ether): Muamua, e fa'apipi'i le polyether i le vaega acetoacetate i pito uma e lua e ala i le dienone po'o le fa'agasologa o le fesuia'iga o le ester o le ethyl acetoacetate ma le polyether polyol, ona fa'asusu lea o le polyether ua ufiufi e le vaega acetoacetate i se amine mono-primary, alkyl alcohol amine po'o le dibasic primary amine e maua ai se imine compound e maualalo le viscosity ma se vaega pito aminobutyrate.
