PPSU, izita resainzi repolyphenylene sulfone resin, is amorphous thermoplastic ine kujeka kwepamusoro uye kugadzikana kwehydrolytic, uye zvigadzirwa zvinogona kumira zvakadzokororwa kuuraya hutachiona.
PPSU yakajairika kupfuura polysulfone (PSU), polyethersulfone (PES) uye polyetherimide (PEI).
Kushandiswa kwePPSU
1. Midziyo yemumba uye midziyo yekudya: inogona kushandiswa kugadzira michina yeovheni yemicrowave, mafirita ekofi, humidifiers, hair dryer, midziyo yekudya, mabhodhoro evana, nezvimwe.
2. Zvigadzirwa zvedhijitari: panzvimbo yemhangura, zingi, aluminium uye zvimwe zvinhu zvesimbi, kugadzirwa kwemakesi ekurindira, zvinhu zvekushongedza zvemukati uye mafotokopi, zvikamu zvekamera uye zvimwe zvakanyatsorongeka zvikamu.
3. Mechanical industry: kunyanya kushandisa girazi fiber reinforced specifications, zvigadzirwa zvine maitiro ezvinokambaira kuramba, kuoma, dimensional kugadzikana, nezvimwewo, zvakakodzera kugadzirwa kwekubereka mabhuraketi uye mechanical zvikamu shell nezvimwe zvakadaro.
4. Munda wezvokurapa uye wehutano: wakanyatsokodzera mazino uye midziyo yekuvhiya, disinfection mabhokisi (mahwendefa) uye zvakasiyana-siyana zvisiri zvevanhu zvinogadziriswa zvemishonga.
Kuonekwa kwePPSU
Natural yellowish semi-transparent particles kana opaque particles.
Zvekuita zvemuviri zvinodiwa zvePPSU
| Density (g/cm³) | 1.29 | Mold Shrinkage | 0.7% |
| Kunyunguduka tembiricha (℃) | 370 | Kutorwa kwemvura | 0.37% |
| Kuomesa tembiricha (℃) | 150 | Nguva yekuomesa (h) | 5 |
| Mold tembiricha (℃) | 163 | Jekiseni tembiricha (℃) | 370~390 |
Mapoinzi akati wandei anofanirwa kutariswa kana uchigadzira zvigadzirwa zvePPSU uye mold
1. The fluidity yePSU yakanyunguduka yakashata, uye chiyero chekunyunguduka kuyerera kureba kusvika kumadziro emadziro anenge 80 chete. Naizvozvo, madziro emadziro ezvigadzirwa zvePSU hazvifanirwe kunge zvisingasviki 1.5mm, uye mazhinji acho ari pamusoro pe2mm.
Zvigadzirwa zvePSU zvinonzwa kune notches, saka arc shanduko inofanirwa kushandiswa kurudyi kana acute angles. Iyo yekuumba shrinkage yePSU yakagadzikana, inova 0.4% -0.8%, uye iyo melt inoyerera nzira yakangofanana neiyo munzira yakatwasuka. Demo rekona rinofanira kunge riri 50:1. Kuti uwane zvigadzirwa zvakajeka uye zvakachena, kushata kwepamusoro kwegomba re mold kunodiwa kuti ive yakawanda kupfuura Ra0.4. Kuti ufambise kunyungudika kuyerera, sprue ye mold inodiwa kuve ipfupi uye gobvu, dhayamita rayo rinosvika 1/2 yehukobvu hwechigadzirwa, uye ine kutsetseka kwe3 ° ~ 5 °. Chikamu chemuchinjikwa che shunt chiteshi chinofanira kunge chiri arc kana trapezoid kudzivirira kuvepo kwekubhenda.
2. Chimiro chegedhi chinogona kugadziriswa nechigadzirwa. Asi ukuru hunofanira kuva hukuru sezvinobvira, chikamu chakarurama chegedhi chinofanira kuva chipfupi sezvinobvira, uye kureba kwayo kunogona kudzorwa pakati pe 0.5 ~ 1.0mm. Nzvimbo yechiteshi chekudya inofanira kuiswa pamadziro akakora.
3. Isai makomba anotonhora akakwana pamagumo esprue. Nekuti zvigadzirwa zvePSU, kunyanya zvigadzirwa zvakatetepa-zvakakomberedzwa, zvinoda yakakwira jekiseni kudzvanywa uye nekukurumidza jekiseni chiyero, maburi akanaka epombi kana grooves anofanirwa kusetwa kuitira kupedza mweya muforoma nenguva. Hudzamu hwemavhavha aya kana grooves inofanirwa kudzorwa pazasi 0.08mm.
4. Kuiswa kwekushisa kwe mold kunofanira kubatsira kuvandudza fluidity yePSU yakanyunguduka panguva yekuzadza firimu. Iyo tembiricha yekuumbwa inogona kunge yakakwira kusvika 140 ℃ (inenge 120 ℃).
