Styrene-Ethylene/Butylene block copolymer

Eechi chintu nchintu chili kabotu, chiboneka kabotu cha Styrene-Ethylene/Butylene-Styrene (SEBS). Bupange bwamolekyula bwayo bwakabambilwa kuti bube amulimu mubotu, uuzyibidwe azintu zipati zitobela:

(1) Kukwabililwa Kubotu Kwamuwo Akupya: Ibbuloki lyaakati-kati lizwide (ethylene/butylene) lipa nguzu zyakukazya kunyonyooka kuzwa ku ozone, oxygen, a UV radiation, kupa kuti kakuli kabotu kwachiindi chilamfu mukubelesegwa anze. Alimwi ilabamba bube bwayo muchiindi chakupya loko, mpawo ilakwabilila kupya.

(2) Nguzu zyaatala: Chintu eechi chilaanguzu zyakukwela zigambya, kukazyigwa kutyoka, akukazya kutyoka, eezi zipa kuti kube zintu ziyumu akukkala kwachiindi chilamfu.

(3) Kweendelana kabotu amapulasitiki: Chitondezya kweendelana kubotu azibelesyo zyiingi zyama thermoplastics, zilimbuli polypropylene (PP) a polystyrene (PS), kupa kuti kube kusanganya kuuba-uba mukupanga ma polymer alloys aajisi bube busumpukide.

(4) Kusalala akuchincha: Bupange bwamulongo bulagwasya kuti bube antangalala, mpawo mpawo bupa kuyuma kupati akusanduka kubotu loko muchiindi chakutontola.

Akaambo kazyintu zyakwe ziyumu, eeyi SEBS copolymer ibelekela mbuli chintu chikonzya kuchincha antoomwe a polymer mumakwebo aasiyene. Kubelesyegwa kwayo kutaanzi kubikkilizya:

(1) Kuchincha kwapulasitiki: Ibelesyegwa mbuli chintu chikonzya kuchincha mapulasitiki mayumu, mpawo chisumpula kuyuma akujata kabotu kakunyina kusiya nzila yakuchita zintu.

(2) Zinamatika: Chibeleka mbuli chintu chipati mukupanga zintu zibeleka obotu, zizumanana kupya (HMAs) azintu zikwabilila, zipa kuti kube kujatana kuyumu akujatana kwa UV.

(3) Kusanganya Kuchincha: Chibeleka mbuli chintu chakusaanguna chakupanga zintu zipangidwe a thermoplastic elastomer (TPE) zyeendelana abuyumuyumu, mubala, akubeleka kabotu.

(4) Zitoyi azintu zyakubelesya: Nchibotu mukupanga zintu zikwabilidwe, ziyumu, alimwi zitazungaani mbuli zisobano, zijatisyo, azijatisyo.

(5) Kuchincha Asphalt: Zisumpula kuchincha, kuyuma, akuyuma kwazibelesyo zyakujatila ziluli zibelesyegwa mukuyaka ŋanda akubamba nzila.
