Matrix a resin ea metsoako ea thermoplastic e kenyelletsa lipolasetiki tsa boenjiniere tse akaretsang le tse khethehileng, 'me PPS ke moemeli ea tloaelehileng oa lipolasetiki tse khethehileng tsa boenjiniere, tse tsejoang ka hore ke "khauta ea polasetiki".Melemo ea ts'ebetso e kenyelletsa lintlha tse latelang: ho hanyetsa mocheso o motle, thepa e ntle ea mochini, ho hanyetsa kutu, le ho itima mollo ho fihlela boemong ba UL94 V-0.Hobane PPS e na le melemo ea ts'ebetso e kaholimo, 'me ha e bapisoa le lipolasetiki tse ling tsa boenjiniere ba thermoplastic tse sebetsang hantle, e na le litšobotsi tsa ho sebetsa habonolo le litšenyehelo tse tlase, ka hona e fetohile matrix a resin e ntle haholo bakeng sa ho etsa thepa e kopaneng.

PPS hammoho le lisebelisoa tse entsoeng ka khalase e khutšoanyane (SGF) li na le melemo ea matla a phahameng, ho hanyetsa mocheso o phahameng, ho thibela lelakabe, ho sebetsa habonolo, litšenyehelo tse tlaase, joalo-joalo.
PPS lengthened glass fiber (LGF) composite material na le melemo ea high toughness, low warpage, fatigue resistance, ponahalo e ntle ea sehlahisoa, joalo-joalo E ka sebelisoa bakeng sa li-impellers, li-casing casings, manonyeletso, li-valve, li-impellers tsa lik'hemik'hale le li-casings, metsi a pholileng. li-impellers le Likhetla, likarolo tsa lisebelisoa tsa lapeng, joalo-joalo.

Joale ke liphapang life tse khethehileng tsa thepa ea khalase e khuts'oane (SGF) le fiber ea khalase e telele (LGF) e matlafalitsoeng ke likarolo tsa PPS?

Thepa e felletseng ea likarolo tsa PPS/SGF (fiber e khuts'oane ea khalase) le likarolo tsa PPS/LGF (fiber e telele ea khalase) li ne li bapisoa.Lebaka leo ka lona ts'ebetso ea ho qhibiliha ea ho qhibiliha e sebelisoang ha ho lokisoa "screw granulation" ke hore ho kenngoa ha fiber bundle ho phethahala ka har'a hlobo ea ho kenngoa, 'me fiber ha e senyehe.Qetellong, ka papiso ea data ea thepa ea mochini oa bobeli, e ka fana ka ts'ehetso ea tekheniki bakeng sa basebetsi ba mahlale le theknoloji ba lehlakoreng la ts'ebeliso ha ba khetha lisebelisoa.

Tlhahlobo ea thepa ea mechine
Likhoele tse matlafatsang tse kentsoeng ka har'a matrix ea resin li ka etsa skeleton e tšehetsang.Ha thepa e kopantsoeng e kenngoa ka matla a ka ntle, likhoele tse matlafatsang li ka jara ka katleho karolo ea meroalo e ka ntle;ka nako e ts'oanang, e ka monya matla ka ho robeha, deformation, joalo-joalo, le ho ntlafatsa thepa ea mochine ea resin.

Ha likhalase tsa khalase li ntse li eketseha, likhoele tse ngata tsa khalase ka har'a lisebelisoa tse kopaneng li tlas'a matla a kantle.Ka nako e ts'oanang, ka lebaka la ho eketseha ha palo ea likhalase tsa khalase, matrix a resin pakeng tsa likhoele tsa khalase e ba mosesaane, e leng se loketseng ho aha liforeimi tse matlafalitsoeng tsa khalase;ka hona, ho eketseha ha likhalase tsa khalase ho etsa hore thepa e kopantsoeng e fetise khatello e eketsehileng ho tloha ho resin ho ea ho fiber ea khalase tlas'a mojaro o ka ntle, e leng ho ntlafatsang ka katleho thepa e tsitsitseng le e kobehang ea thepa e kopantsoeng.
Thepa e tsitsitseng le e feto-fetohang ea metsoako ea PPS/LGF e phahame ho feta ea lihlopha tsa PPS/SGF.Ha karolo e kholo ea fiber ea khalase e le 30%, matla a matla a PPS / SGF le PPS / LGF composite ke 110MPa le 122MPa, ka ho latellana;Matla a flexural ke 175MPa le 208MPa, ka ho latellana;flexural elastic moduli ke 8GPa le 9GPa, ka ho latellana.
Matla a ho tsitsa, matla a flexural le modulus elastic elastic ea metsoako ea PPS / LGF e ile ea eketseha ka 11.0%, 18.9% le 11.3%, ka ho latellana, ha e bapisoa le lihlopha tsa PPS / SGF.Sekhahla sa ho boloka bolelele ba fiber ea khalase linthong tse kopaneng tsa PPS/LGF se phahame.Tlas'a lintho tse tšoanang tsa fiber ea khalase, thepa e kopantsoeng e na le khanyetso e matla ea mojaro le thepa e ntle ea mochini.
