Alkyl Polyether: O se Mea Mata Fa'akemikolo e Tele-Fa'amoemoega mo Fa'aoga Eseese-1
Vaega Autu o Talosaga
I le alamanuia o vailaʻau, e faʻaaogaina alkyl polyethers o ni mea mata mo polyurethane foams, adhesives, sealants, ma elastomers. E faʻaaogaina lautele polyurethane foams i meaafale, faʻamalū, nofoa taʻavale, ma mea e faʻamafanafana ai fale. O adhesives ma sealants polyurethane e faʻaaogaina i le faʻapotopotoga o fale, taʻavale, ma masini eletise.
I le alamanuia o vailaʻau, e avea alkyl polyethers o ni mea e faʻaopoopo i ai ma ni mea e faʻasusu ai i vailaʻau, e faʻaleleia atili ai lo latou mautu ma le solubility. E faʻaaogaina foʻi e gaosia ai mea e faʻaitiitia ai le foam, surfactants, ma wetting agents, e faʻaaogaina lautele i le gutu, isu sprays, mataua mata, mataua taliga, ma shampoos.
I pisinisi ie ma pepa, e fa'aaogaina alkyl polyethers o ni mea e fa'amalūlū ai, mea e tete'e ai i le vai, ma mea e fa'asusu ai. Latou te fa'aleleia atili ai le vaivai ma uiga e tete'e ai i le vai o ie ma fa'aleleia atili ai le lelei o le pepa ma le lelei o le gaosiga i le gaosiga o pepa.
I vaega o le fasimoli ma oloa tausiga o le tagata lava ia, e fa'aaogaina ai le alkyl polyethers o ni surfactants ma ni emulsifiers. E iai lo latou gafatia lelei i le fa'amamāina, fa'apupula, fa'amautu o le foam, fa'asusu, ma le fa'asusuina, e fa'aaogaina lautele i shampoos, fa'amama tino, vaila'au fa'amama lima, ma vaila'au fufulu lavalava.
E le gata i lea, o le alkyl polyethers e faʻaaogaina o ni mea e faʻamama ai le kesi ma mea e faʻasusu ai le suāuu i le gaosiga o le suauʻu, faʻapea foʻi ma mea e faʻamālūlū ai le kesi ma mea e faʻasusu ai le suāuu i le gaosiga o uʻamea.
O le faagasologa o le gaosiga o alkyl polyethers e masani ona aofia ai le togafitiga muamua o initiators ma catalysts, ring-opening polymerization reactions, ma laasaga o le faagasologa mulimuli e pei o le neutralization, adsorption, dehydration, filtration, ma le distillation.

I se aotelega
I se aotelega, o alkyl polyethers, o ni mea mata e tele galuega fa'atino, e taua tele i le tele o alamanuia. E le gata ina fa'aleleia atili ai le fa'atinoga ma le lelei o oloa ae lagolagoina fo'i le atina'eina o alamanuia fa'aonaponei. Faatasi ai ma le alualu i luma faifai pea o tekinolosi, o le a sili atu ona lautele avanoa e fa'aoga ai alkyl polyethers.
