Haina Surfactant Kaihanga, Kaiwhakarato, wheketere

Ko nga momo hua o te Surfactant, he kaihanga rongonui mai i Haina, he kaiwhakarato / wheketere matou , , me te Amphoteric Surfactants, nga hua o te kounga teitei o te R&D me te whakangao, kei a matou te ratonga whai muri-hoko me te tautoko hangarau. Titiro whakamua ki to mahi tahi!

Ko te Surfactant, e mohiotia ana ko te surfactant, he puhui ka taea te whakaiti i te awangawanga o te mata, te awangawanga atanga ranei i waenga i nga wai e rua, te wai-hau, te wai-totoka ranei. He amphiphilic te hanga ngota ngota surfactants: he roopu hydrophilic tetahi pito, he roopu hydrophobic tetahi pito; ko te roopu hydrophilic he roopu polar, penei i te waikawa carboxylic, te waikawa sulfonic, te waikawa sulfuric, te amino, te roopu amine ranei me ona tai, nga roopu hydroxyl, nga roopu amide, nga here ether, me etahi atu ka taea hoki te whakamahi hei roopu hydrophilic polar; i te nuinga o nga wa ko nga roopu hydrophobic he mekameka waiwaro kore-polar, penei i nga mekameka waiwaro neke atu i te 8 ngota waro. Ka wehewehea nga katote ki roto i nga katote surfactants (tae atu ki te cationic surfactants, anionic surfactants, amphoteric surfactants), nonionic surfactant, pūhui surfactant, te tahi atu surfactants, etc.

Ko nga ngota ngota Surfactant he amphiphilicity ahurei: ko tetahi pito he roopu polar hydrophilic, whakapotohia hei roopu hydrophilic, e mohiotia ana ano ko te roopu oleophobic or oleophobic ranei, penei - OH- COOH、-SO3H、-NH2。 Na te poto o enei roopu mahi, i etahi wa ka kiia ko nga upoko hydrophilic. Ko tetahi atu pito he roopu kore-polar he lipophilic, whakapotohia hei roopu lipophilic, e mohiotia ana ko te roopu hydrophobic, te roopu hydrophobic ranei, penei i te R - (alkyl), Ar - (aryl). Na te poto o enei roopu mahi, i etahi wa ka kiia ko nga hiku hydrophobic. E rua nga momo roopu rapoi he hanga rereke me nga ahuatanga kei nga pito e rua o te taua ngota ka honoa e nga here matū, ka hanga i te hanga hangarite me te polar, na reira ka whakawhiwhia tenei ngota motuhake ki nga ahuatanga hydrophilic me te oleophilic, engari ehara i te katoa. āhuatanga hydrophilic oleophilic ranei. Ko te hanganga ahurei o te surfactants e kiia ana ko te "hanganga amphiphilic", na reira ka kiia nga ngota ngota haumanu he "ngota ngota amphiphilic".
