Matrix a resin a thermoplastic composites amaphatikizapo mapulasitiki wamba ndi apadera aukadaulo, ndipo PPS ndi yoyimira pulasitiki yapadera yaukadaulo, yomwe imadziwika kuti "golide wapulasitiki". Ubwino wa magwiridwe antchito ndi awa: kukana kutentha bwino, mphamvu zabwino zamakanika, kukana dzimbiri, komanso kudziwotcha mpaka mulingo wa UL94 V-0. Chifukwa PPS ili ndi zabwino zomwe zili pamwambapa, ndipo poyerekeza ndi mapulasitiki ena apamwamba a thermoplastic engineering, ili ndi mawonekedwe osavuta kuikonza komanso mtengo wotsika, kotero yakhala matrix yabwino kwambiri ya resin popanga zinthu zophatikizika.

Zipangizo zopangidwa ndi PPS komanso ulusi wagalasi lalifupi (SGF) zili ndi ubwino wa mphamvu zambiri, kukana kutentha kwambiri, kuletsa moto, kukonza kosavuta, mtengo wotsika, ndi zina zotero.
Zipangizo zopangidwa ndi ulusi wagalasi wotalikitsidwa wa PPS (LGF) zili ndi ubwino wa kulimba kwambiri, kupotoka kochepa, kukana kutopa, mawonekedwe abwino azinthu, ndi zina zotero. Zingagwiritsidwe ntchito pa ma impeller, ma pomp casings, ma joints, ma valve, ma chemical pump impellers ndi ma casings, ma cooling water impellers ndi ma Shells, zida zapakhomo, ndi zina zotero.

Ndiye kodi pali kusiyana kotani pakati pa zinthu zomwe zimapangidwa ndi ulusi waufupi wagalasi (SGF) ndi ulusi wautali wagalasi (LGF) wolimbikitsidwa ndi PPS?

Kapangidwe kake ka zinthu zopangidwa ndi PPS/SGF (ulusi waufupi wagalasi) ndi zinthu zopangidwa ndi PPS/LGF (ulusi wautali wagalasi) kanayerekezeredwa. Chifukwa chomwe njira yosungunula imagwiritsa ntchito pokonzekera screw granulation ndikuti kuyika kwa ulusi kumachitika mu nkhungu yoyikamo, ndipo ulusiwo suwonongeka. Pomaliza, kudzera mu kuyerekeza deta ya zinthu ziwirizi, imatha kupereka chithandizo chaukadaulo kwa akatswiri asayansi ndi ukadaulo omwe amagwiritsa ntchito posankha zipangizo.

Kusanthula katundu wa makina
Ulusi wolimbitsa womwe umawonjezeredwa mu resin matrix ukhoza kupanga mafupa othandizira. Pamene zinthu zophatikizika zikugwiritsidwa ntchito ndi mphamvu yakunja, ulusi wolimbitsa umatha kugwira bwino ntchito ya katundu wakunja; nthawi yomweyo, umatha kuyamwa mphamvu kudzera mu kusweka, kusintha, ndi zina zotero, ndikuwonjezera mphamvu zamakina a resin.

Pamene kuchuluka kwa ulusi wagalasi kukuchulukirachulukira, ulusi wambiri wagalasi mu zinthu zopangidwa ndi ...
Mphamvu zokoka ndi zopindika za PPS/LGF composites zimakhala zapamwamba kuposa za PPS/SGF composites. Pamene gawo lalikulu la ulusi wagalasi ndi 30%, mphamvu zokoka za PPS/SGF ndi PPS/LGF composites ndi 110MPa ndi 122MPa, motsatana; Mphamvu zopindika ndi 175MPa ndi 208MPa, motsatana; flexural elastic moduli ndi 8GPa ndi 9GPa, motsatana.
Mphamvu yokoka, mphamvu yokoka, ndi mphamvu yokoka ya zinthu zopangidwa ndi PPS/LGF zinawonjezeka ndi 11.0%, 18.9% ndi 11.3%, motsatana, poyerekeza ndi zinthu zopangidwa ndi PPS/SGF. Kuchuluka kwa ulusi wagalasi womwe umasungidwa mu zinthu zopangidwa ndi PPS/LGF ndi kwakukulu. Pansi pa kuchuluka kwa ulusi wagalasi womwewo, zinthu zopangidwa ndi ...
