China Wokwera pamwamba Wopanga, Wopereka, Fakitale

Zogulitsa za Surfactant, ndife ojambula apadera ochokera ku China, ndife ogulitsa/fakitale ya , , ndi Amphoteric Surfactants, zogulitsa zapamwamba kwambiri za R & D zopangira ma surfactants ndi kupanga, tili ndi ntchito yabwino yotsatsa pambuyo potsatsa komanso chithandizo chaukadaulo. Yembekezerani mgwirizano wanu!

Surfactant, yomwe imadziwikanso kuti surfactant, ndi chinthu chomwe chimatha kuchepetsa kwambiri kupsinjika kwapamadzi kapena kukangana kwapakati pazamadzimadzi ziwiri, gasi wamadzimadzi, kapena zolimba zamadzimadzi. Mapangidwe a maselo a surfactants ndi amphiphilic: mapeto amodzi ndi gulu la hydrophilic ndipo mapeto ena ndi gulu la hydrophobic; gulu la hydrophilic nthawi zambiri limakhala gulu la polar, monga carboxylic acid, sulfonic acid, sulfuric acid, amino kapena amine gulu ndi mchere wake , magulu a hydroxyl, magulu a amide, ether bonds, etc. angagwiritsidwenso ntchito ngati magulu a polar hydrophilic; pamene magulu hydrophobic nthawi zambiri sanali polar hydrocarbon unyolo, monga unyolo hydrocarbon ndi maatomu mpweya oposa 8. Ma surfactants amagawidwa m'ma ionic surfactants (kuphatikiza ma cationic surfactants, anionic surfactants, amphoteric surfactants), ma nonionic surfactants, ma surfactants ena, ndi zina zambiri.

Mamolekyu a surfactant ali ndi amphiphilicity yapadera: mapeto amodzi ndi gulu la hydrophilic polar, lofupikitsidwa ngati gulu la hydrophilic, lomwe limadziwikanso kuti gulu la oleophobic kapena oleophobic, monga - OH- COOH, -SO3H, -NH2. nthawi zina amatchedwa mitu ya hydrophilic. Mapeto ena ndi gulu lopanda polar lomwe ndi lipophilic, lofupikitsidwa ngati lipophilic gulu, lomwe limadziwikanso kuti gulu la hydrophobic kapena gulu la hydrophobic, monga R - (alkyl), Ar - (aryl). Chifukwa cha kutalika kwaufupi kwa magulu ogwira ntchitowa, nthawi zina amatchedwa michira ya hydrophobic. Mitundu iwiri yamagulu a mamolekyu okhala ndi zomanga zotsutsana kotheratu ndi katundu ali pa malekezero awiri a molekyulu yomweyo ndipo olumikizidwa ndi zomangira za mankhwala, kupanga mawonekedwe asymmetric ndi polar, motero amapatsa molekyulu yapaderayi yokhala ndi hydrophilic ndi oleophilic, koma osati yonse. mawonekedwe a hydrophilic kapena oleophilic. Mapangidwe apadera a surfactants amatchedwa "amphiphilic structure", ndipo mamolekyu a surfactant nthawi zambiri amatchedwa "amphiphilic molecules".
