Menene polyphenylene sulfide (PPS)
PPS yana nufin Polyphenylene Sulphide babban ingantacciyar injin thermoplastic ne wanda aka bambanta ta hanyar haɗakar kaddarorin sa.
Semi-crystalline, opaque da m polymer wanda ke da babban wurin narkewa (280°C) kuma ya ƙunshi raka'o'in para-phenylene waɗanda ke musanya tare da haɗin gwiwar sulfide.
PPS suna da ingantacciyar ma'auni na kaddarorin kamar juriya na harshen wuta, kyakkyawan juriya na sinadarai, juriya mai zafi, ƙarfin girma, ƙarfin injin na musamman da rufin lantarki.
Ana iya sarrafa PPS cikin sauƙi saboda ƙarfinsa yana ƙaruwa da yanayin zafi mai girma.
Duk waɗannan halaye masu ban sha'awa sun sa PPS ya zama kyakkyawan zaɓi ga thermosets da karafa don amfani da su a aikace-aikace da kayan aiki da yawa, sassan mota da na lantarki.
Yawancin abokan ciniki a cikin sassan gyare-gyaren allura na PPS suna da nau'in tunani na inertia: babu zafin jiki, ƙofar ba ta da girma, ƙarancin shayewa, ɗan gajeren lokacin sanyaya.
Mold zafin jiki na iya sa saman samfurin da sauri crystallization, santsi ba tare da iyo fiber kwarara, mafi muhimmanci shi ne don sa ƙarfin samfurin ya ƙarfafa sosai; Girman ƙofar yana rinjayar adadin allurar filastik, kuma za a sami buƙatun don saitin matsa lamba da adadin allura. Hakanan zai yi tasiri akan asarar matsa lamba mai nisa na samfuran ma'ana da yawa.
Rashin isassun shaye-shaye zai haifar da saurin tara iskar gas, yana haifar da ƙonawa da ƙima akan saman da wutsiya na samfurin.
PPS kanta kayan zai ƙunshi sulfide da sauran ƙananan adadin hazo na polyphenylbiphenyl polymer, don haka ƙirar shayewa yana da mahimmanci!
Shortan lokacin sanyaya, bai dace da cikakken crystallization na samfurin ba!
Domin ya bi samar da iya aiki, da yawa abokan ciniki kai tsaye rage samar sake zagayowar zuwa babban har, sakamakon da guntu abu crystallization sake zagayowar, wanda ba conducive zuwa ga bayani na sabon abu a farkon daya!
Madaidaicin zaɓi na kayan, masana'antar kimiyya!
Bayar da goyon bayan tsayawa ɗaya daga albarkatun ƙasa, ƙira, matakai, samfuran da aka gama, gunaguni na abokin ciniki da sauran cikakken sarkar!
Babban kayan aikin da ke kewaye da ku masanan mafita na tsayawa ɗaya!
