Matrix ea resin ea metsoako ea thermoplastic e kenyelletsa polasetiki ea boenjiniere e akaretsang le e khethehileng, 'me PPS ke moemeli ea tloaelehileng oa polasetiki e khethehileng ea boenjiniere, e tsejoang ka tloaelo e le "khauta ea polasetiki". Melemo ea ts'ebetso e kenyelletsa lintlha tse latelang: ho hanyetsa mocheso hantle, thepa e ntle ea mechini, ho hanyetsa mafome, le ho iketsa eka e tuka ho fihlela boemong ba UL94 V-0. Hobane PPS e na le melemo ea ts'ebetso e boletsoeng ka holimo, 'me ha e bapisoa le polasetiki e meng ea boenjiniere ea thermoplastic e sebetsang hantle, e na le litšobotsi tsa ts'ebetso e bonolo le litšenyehelo tse tlase, kahoo e fetohile matrix e ntle ea resin bakeng sa ho etsa thepa ea metsoako.

Thepa e kopaneng ea PPS hammoho le fiber e khutšoanyane ea khalase (SGF) e na le melemo ea matla a phahameng, ho hanyetsa mocheso o phahameng, ho thibela malakabe, ho sebetsa habonolo, litšenyehelo tse tlase, jj.
Thepa e kopaneng ea fiber ea khalase e telele ea PPS (LGF) e na le melemo ea ho ba thata haholo, ho ba le lekhalo le tlase, ho hanyetsa mokhathala, ponahalo e ntle ea sehlahisoa, jj. E ka sebelisoa bakeng sa li-impeller, li-casing tsa pompo, manonyeletso, li-valve, li-impeller tsa pompo ea lik'hemik'hale le li-casing, li-impeller tsa metsi a pholileng le Li-Shell, likarolo tsa lisebelisoa tsa lapeng, jj.

Joale phapang e tobileng ke efe mabapi le thepa ea fiber e khutšoanyane ea khalase (SGF) le fiber e telele ea khalase (LGF) e matlafalitsoeng ke PPS?

Litšobotsi tse felletseng tsa metsoako ea PPS/SGF (fiber e khutšoanyane ea khalase) le metsoako ea PPS/LGF (fiber e telele ea khalase) li bapisitsoe. Lebaka leo ka lona mokhoa oa ho qhibiliha o sebelisoang ho lokiseng granulation ea screw ke hore ho kenngoa ha sephutheloana sa fiber ho bonoa ka har'a hlobo ea ho kenngoa, 'me fiber ha e senyehe. Qetellong, ka papiso ea data ea litšobotsi tsa mechini tsa tse peli, e ka fana ka tšehetso ea tekheniki bakeng sa basebetsi ba saense le theknoloji ba lehlakoreng la ts'ebeliso ha ba khetha thepa.

Tlhahlobo ea thepa ea mechini
Likhoele tse matlafatsang tse ekelitsoeng ka har'a resin matrix li ka etsa masapo a tšehetsang. Ha thepa e kopaneng e tlas'a matla a kantle, likhoele tse matlafatsang li ka jara karolo ea meroalo ea kantle ka katleho; ka nako e ts'oanang, li ka monya matla ka ho robeha, ho fetoha, jj., le ho ntlafatsa litšobotsi tsa mechini tsa resin.

Ha tekanyo ea faeba ea khalase e eketseha, likhoele tse ngata tsa khalase tse ka har'a thepa e kopaneng li hlaseloa ke matla a kantle. Ka nako e ts'oanang, ka lebaka la keketseho ea palo ea likhoele tsa khalase, matrix ea resin pakeng tsa likhoele tsa khalase e ba tšesaane, e leng se thusang haholo ho hahoa ha liforeimi tse matlafalitsoeng tsa faeba ea khalase; ka hona, keketseho ea tekanyo ea faeba ea khalase e nolofalletsa thepa e kopaneng ho fetisetsa khatello e eketsehileng ho tloha resin ho ea ho faeba ea khalase tlas'a mojaro oa kantle, e leng se ntlafatsang ka katleho thepa ea ho tsitlella le ho kobeha ha thepa e kopaneng.
Matla a ho tensile le ho flexural a di-composite tsa PPS/LGF a phahame ho feta a di-composite tsa PPS/SGF. Ha karolo e kgolo ya faeba ya khalase e le 30%, matla a ho tensile a di-composite tsa PPS/SGF le PPS/LGF ke 110MPa le 122MPa, ka ho latellana; Matla a ho flexural ke 175MPa le 208MPa, ka ho latellana; moduli ya flexural elastic ke 8GPa le 9GPa, ka ho latellana.
Matla a ho tensile, matla a ho flexural le modulus ea ho flexural elastic ea metsoako ea PPS/LGF li ekelitsoe ka 11.0%, 18.9% le 11.3%, ka ho latellana, ha li bapisoa le metsoako ea PPS/SGF. Sekhahla sa ho boloka bolelele ba fiber ea khalase ka har'a thepa ea motsoako ea PPS/LGF se phahame. Tlas'a tekanyo e tšoanang ea fiber ea khalase, thepa ea motsoako e na le khanyetso e matla ea mojaro le thepa e betere ea mechini.
