SBS ndi chiyani

SBS (styrene-butadiene-styrene) Poly (styrene-butadiene-styrene) kapena SBS, ndi rabara yolimba yomwe imagwiritsidwa ntchito kusinthira phula, kupanga nsapato, zopondapo matayala, ndi malo ena omwe kulimba ndikofunikira.Ndi mtundu wa copolymer wotchedwa block copolymer.Unyolo wake wamsana umapangidwa ndi magawo atatu.Choyamba ndi unyolo wautali wa polystyrene, pakati ndi unyolo wautali wa polybutadiene, ndipo gawo lomaliza ndi gawo lina lalitali la polystyrene.Polystyrene ndi pulasitiki yolimba, ndipo izi zimapangitsa SBS kukhala yolimba.Polybutadiene ndi rubbery, ndipo izi zimapatsa SBS mawonekedwe ake ngati mphira.Kuphatikiza apo, maunyolo a polystyrene amatha kuphatikizika.Gulu limodzi la styrene la molekyulu imodzi ya SBS likalumikizana ndi gulu limodzi, ndipo unyolo wina wa polystyrene wa molekyulu ya SBS yolumikizana ndi gulu lina, magulu osiyanasiyana amamangidwa pamodzi ndi unyolo wa rubbery polybutadiene.Izi zimapatsa zinthuzo mphamvu yosunga mawonekedwe ake atatambasulidwa
