PPSU, izina ry'ubumenyi rya polifhenylene sulfone resin, ni amorphous thermoplastique ifite umucyo mwinshi hamwe na hydrolytike ihamye, kandi ibicuruzwa birashobora kwihanganira kwanduza amavuta.
PPSU isanzwe kuruta polysulfone (PSU), polyethersulfone (PES) na polyetherimide (PEI).

Kugaragara kwa PPSU
Ibara ry'umuhondo risanzwe igice-kibonerana cyangwa ibice bitagaragara.
Imikorere ifatika ya PPSU
Ubucucike (g / cm³) | 1.29 | Kugabanuka | 0.7% |
Gushonga ubushyuhe (℃) | 370 | Kwinjiza amazi | 0.37% |
Ubushyuhe bwumye (℃) | 150 | Igihe cyo kumisha (h) | 5 |
Ubushyuhe bukabije (℃) | 163 | Ubushyuhe bwo gutera inshinge (℃) | 370 ~ 390 |
Ingingo nyinshi zigomba kwitonderwa mugihe dushushanya ibicuruzwa na PPSU
1.
Ibicuruzwa bya PSU byumva neza, bityo inzibacyuho arc igomba gukoreshwa iburyo cyangwa bukaze. Kugabanuka kwa PSU birahagaze neza, ni 0.4% -0.8%, kandi icyerekezo cyo gutembera gushonga ahanini ni kimwe nicyerekezo cyerekezo. Inguni ya demoulding igomba kuba 50: 1. Kugirango ubone ibicuruzwa byiza kandi bisukuye, uburinganire bwubuso bwububiko bwububiko burasabwa kurenza Ra0.4. Kugirango byoroherezwe gutemba, isoko yububumbyi isabwa kuba mugufi kandi ikabyimbye, diameter yayo byibura 1/2 cyubunini bwibicuruzwa, kandi ifite umusozi wa 3 ° ~ 5 °. Igice cyambukiranya umuyoboro wa shunt kigomba kuba arc cyangwa trapezoid kugirango wirinde kubaho kugoramye.
2. Imiterere y irembo irashobora kugenwa nigicuruzwa. Ariko ubunini bugomba kuba bunini bushoboka, igice kigororotse cy irembo kigomba kuba kigufi gishoboka, kandi uburebure bwacyo bushobora kugenzurwa hagati ya 0.5 ~ 1.0mm. Umwanya wicyambu cyo kugaburira ugomba gushyirwaho kurukuta rwinshi.
3. Shiraho ibyobo bikonje bihagije kumpera yisoko. Kuberako ibicuruzwa bya PSU, cyane cyane ibicuruzwa bikikijwe n'inkuta, bikenera umuvuduko mwinshi wo gutera inshinge nigipimo cyihuse cyo guterwa, hagomba gushyirwaho umwobo mwiza cyangwa ibinogo kugirango ushire umwuka mubi mugihe. Ubujyakuzimu bw'imyanda cyangwa ibiti bigomba kugenzurwa munsi ya 0.08mm.
4. Gushiraho ubushyuhe bwububiko bugomba kuba ingirakamaro mugutezimbere amazi ya PSU gushonga mugihe cyo kuzuza firime. Ubushyuhe bwububiko burashobora kuba hejuru ya 140 ℃ (byibuze 120 ℃).
