PPSU, lebitso la saense la polyphenylene sulfone resin, ke thermoplastic ea amorphous e nang le pepenene e phahameng le botsitso ba hydrolytic, 'me lihlahisoa li khona ho mamella ho bolaoa ha mouoane khafetsa.
PPSU e tloaelehile ho feta polysulfone (PSU), polyethersulfone (PES) le polyetherimide (PEI).
Tšebeliso ea PPSU
1. Lisebelisoa tsa ka tlung le lijana tsa lijo: li ka sebelisoa ho etsa lisebelisoa tsa onto ea microwave, lihitara tsa kofi, li-humidifiers, li omisa moriri, lijana tsa lijo, libotlolo tsa bana, joalo-joalo.
2. Lihlahisoa tsa dijithale: ho e-na le koporo, zinki, aluminium le lisebelisoa tse ling tsa tšepe, ho etsoa ha mekotla ea ho shebella, lisebelisoa tsa ho khabisa ka hare le li-photocopiers, likarolo tsa lik'hamera le likarolo tse ling tse nepahetseng tsa meralo.
3. Indasteri ea mechine: haholo-holo sebelisa likhalase tsa khalase tse matlafalitsoeng, lihlahisoa li na le litšoaneleho tsa khanyetso ea creep, ho thatafala, botsitso ba dimensional, joalo-joalo, tse loketseng bakeng sa tlhahiso ea li-brackets tse belehang le likhetla tsa likarolo tsa mechine joalo-joalo.
4. Tšimo ea bongaka le bophelo bo botle: e loketse haholo lisebelisoa tsa meno le tsa ho buoa, mabokose a thibelang likokoana-hloko (lipoleiti) le mefuta e sa tšoaneng ea lisebelisoa tsa bongaka tse ke keng tsa kenngoa ke batho.
Ponahalo ea PPSU
Likaroloana tsa tlhaho tse 'mala o mosehla o sa bonahaleng kapa likaroloana tse opaque.
Litlhoko tsa ts'ebetso ea 'mele ea PPSU

Lintlha tse 'maloa li lokela ho eloa hloko ha ho etsoa lihlahisoa tsa PPSU le hlobo
1. Mokelikeli oa PSU o qhibiliha o futsanehile, 'me karo-karolelano ea bolelele ba phallo ea ho qhibiliha le botenya ba lerako ke hoo e ka bang 80 feela. Ka hona, botenya ba lerako la lihlahisoa tsa PSU ha boa lokela ho ba ka tlase ho 1.5mm, 'me boholo ba bona bo ka holimo ho 2mm.
Lihlahisoa tsa PSU li na le kutloelo-bohloko, kahoo phetoho ea arc e lokela ho sebelisoa ka li-angles tse nepahetseng kapa tse matla.The molding shrinkage ea PSU e batla e tsitsitse, e leng 0.4% -0.8%, 'me tataiso ea ho phalla ha melted e hlile e tšoana le ea lehlakoreng le otlolohileng.Sekhahla sa demoulding e lokela ho ba 50:1.E le hore u fumane lihlahisoa tse khanyang le tse hloekileng, ho hloeka ha bokaholimo ba hlobo ho hlokahala ho feta Ra0.4.E le ho tsamaisa phallo ea ho qhibiliha, sprue ea hlobo e hlokeha hore e be khutšoanyane le e teteaneng, bophara ba eona ke bonyane 1/2 ea botenya ba sehlahisoa, 'me e na le moepa oa 3 ° ~ 5 °.Karolo ea sefapano sa mocha oa shunt e lokela ho ba arc kapa trapezoid ho qoba ho ba teng ha li-bends.
2. Sebopeho sa heke se ka khethoa ke sehlahisoa.Empa boholo bo lokela ho ba bo boholo ka hohle kamoo ho ka khonehang, karolo e otlolohileng ea heke e lokela ho ba khutšoanyane ka hohle kamoo ho ka khonehang, 'me bolelele ba eona bo ka laoloa pakeng tsa 0.5 ~ 1.0mm.Boemo ba kou ea phepelo e lokela ho beoa leboteng le teteaneng.
3. Beha likoti tse batang tse lekaneng qetellong ea sprue.Hobane lihlahisoa tsa PSU, haholo-holo tse nang le mabota a masesaane, li hloka khatello e phahameng ea ente le sekhahla se potlakileng sa ente, likoti tse ntle tsa ho ntša metsi kapa li-grooves li lokela ho hlongoa e le hore li felise moea ka har'a hlobo ka nako.Botebo ba li-vents kapa li-grooves tsena li lokela ho laoloa ka tlase ho 0.08mm.
4. Ho beha mocheso oa hlobo ho lokela ho ba molemo ho ntlafatsa metsi a PSU a qhibiliha nakong ea ho tlatsa filimi.Thempereichara ea hlobo e ka ba holimo ho 140 ℃ (bonyane 120 ℃).
