Kodi Polyphenylene Sulphide (PPS) ndi chiyani
PPS imayimira Polyphenylene Sulphide ndi thermoplastic yaukadaulo yaukadaulo yomwe imasiyanitsidwa ndi kuphatikiza kwake kwazinthu.
Ndi polima wa semi-crystalline, opaque komanso wosasunthika yemwe ali ndi malo osungunuka kwambiri (280 ° C) ndipo amakhala ndi mayunitsi a para-phenylene omwe amasinthana ndi sulfide.
PPS ili ndi zinthu zabwino kwambiri monga kukana kwachilengedwe kwamoto, kukana kwamphamvu kwamankhwala, kukana kutentha kwambiri, kuthekera kowoneka bwino, mphamvu zamakina apadera komanso kutsekemera kwamagetsi.
PPS imatha kukonzedwa mosavuta chifukwa kulimba kwake kumawonjezeka ndi kutentha kwakukulu.
Makhalidwe onse odabwitsawa amapangitsa PPS kukhala njira yabwino kwambiri yopangira ma thermosets ndi zitsulo kuti igwiritsidwe ntchito pamapulogalamu angapo ndi zida, zida zamagalimoto ndi zamagetsi.
Makasitomala ambiri m'magawo opangira jakisoni a PPS ali ndi malingaliro amtundu wa inertia: palibe kutentha kwa nkhungu, chipata sichachikulu, kutulutsa kosakwanira, nthawi yochepa yozizira.
Kutentha kwa nkhungu kungapangitse pamwamba pa mankhwala mofulumira crystallization, yosalala popanda kuyandama CHIKWANGWANI otaya, chofunika kwambiri ndi kupanga mphamvu ya mankhwala kwambiri kulimbikitsidwa;kukula kwa chipata kumakhudza kuchuluka kwa jekeseni wa pulasitiki, ndipo padzakhala zofunikira pakuyika kupanikizika ndi mlingo wa jekeseni.Zidzakhalanso ndi zotsatira pa kutaya kwa distal kuthamanga kwa zinthu zambiri.
Kutopa kosakwanira kumapangitsa kuti gasi aziwunjikana mwachangu, zomwe zimapangitsa kuwotcha ndi mawonekedwe pamtunda ndi mchira wa chinthucho.
PPS yokhayo yakuthupi idzakhala ndi sulfide ndi mpweya wina wochepa wa polyphenylbiphenyl polima, kotero kapangidwe ka utsi ndikofunika kwambiri!
Kuzizira kwakanthawi kochepa, kosagwirizana ndi crystallization yazinthu zonse!
Pofuna kukwaniritsa mphamvu kupanga, makasitomala ambiri mwachindunji kuchepetsa mkombero kupanga pamlingo waukulu, chifukwa cha wamfupi zinthu crystallization mkombero, amene si abwino yothetsera chodabwitsa woyamba!
Kusankhidwa koyenera kwa zida, kupanga sayansi!
Perekani chithandizo choyimitsa chimodzi kuchokera ku zipangizo zopangira, nkhungu, njira, zinthu zomalizidwa, madandaulo a makasitomala ndi unyolo wina wathunthu!
Zida zogwirira ntchito zapamwamba zikuzungulirani akatswiri oyimitsa njira imodzi!
