Izindaba Ezidinga Ukunakwa Kwe-PPSU Enqubweni Yokubumba Umjovo

I-PPSU, igama lesayensi le-polyphenylene sulfone resin, iyi-amorphous thermoplastic ene-transparency ephezulu kanye nokuzinza kwe-hydrolytic, futhi imikhiqizo ingakwazi ukumelana nokubulala amagciwane okuphindaphindiwe.

I-PPSU ivame kakhulu kune-polysulfone (PSU), i-polyethersulfone (PES) ne-polyetherimide (PEI).

Ukusetshenziswa kwe-PPSU

1. Izinto zasendlini kanye neziqukathi zokudla: zingasetshenziselwa ukwenza okokusebenza kwe-oven microwave, izifudumezi zekhofi, izinto zokuthambisa, ezomisa izinwele, izitsha zokudla, amabhodlela ezingane, njll.

2. Imikhiqizo yedijithali: esikhundleni sethusi, i-zinc, i-aluminium nezinye izinto zensimbi, ukwakhiwa kwamakesi ewashi, izinto zokuhlobisa zangaphakathi namakhophi, izingxenye zekhamera nezinye izingxenye zesakhiwo esinembayo.

3. Imboni yemishini: ikakhulukazi sebenzisa ukucaciswa okuqinisiwe kwe-glass fibre, imikhiqizo inezici zokumelana nokukhasa, ubulukhuni, ukuzinza kwe-dimensional, njll., efanelekile ukukhiqizwa kwamabakaki okuzala kanye negobolondo lezingxenye zemishini nokunye.

4. Inkundla yezokwelapha nempilo: ifaneleka kakhulu amathuluzi amazinyo nawokuhlinza, amabhokisi okubulala amagciwane (amapuleti) kanye nezinhlobonhlobo zamathuluzi ezokwelapha angatshalwanga abantu.

Ukubonakala kwe-PPSU

Izinhlayiya zemvelo eziphuzi ngokusobala noma izinhlayiya ezikhanyayo.

Izidingo zokusebenza ngokomzimba ze-PPSU

Amaphuzu amaningana kufanele anakwe lapho uklama imikhiqizo ye-PPSU nezibunji

1. I-fluidity ye-PSU yokuncibilika ayilungile, futhi isilinganiso sobude bokuncibilika kokuncibilika kuya ekugqineni kodonga cishe singama-80. Ngakho-ke, ukushuba kodonga lwemikhiqizo ye-PSU akufanele kube ngaphansi kuka-1.5mm, futhi iningi lazo lingaphezu kuka-2mm.

Imikhiqizo ye-PSU iyazwela kumanotshi, ngakho-ke ukuguqulwa kwe-arc kufanele kusetshenziswe kuma-engeli angakwesokudla noma abukhali. Ukuncipha kokubumba kwe-PSU kuzinzile, okungu-0.4% -0.8%, futhi indlela yokuncibilika kokuncibilika iyafana naleyo eqonde mpo. I-engeli yokudiliza kufanele ibe ngu-50:1. Ukuze kutholwe imikhiqizo ekhanyayo nehlanzekile, ubulukhuni obungaphezulu besikhunta kudingeka bube ngaphezu kuka-Ra0.4. Ukuze kube lula ukugeleza kokuncibilika, i-sprue yesikhunta iyadingeka ukuthi ibe mfushane futhi ishube, ububanzi bayo okungenani bube yi-1/2 yobukhulu bomkhiqizo, futhi inomthambeka ongu-3 ° ~ 5 °. Isigaba esiphambanayo sesiteshi se-shunt kufanele sibe i-arc noma i-trapezoid ukuze kugwenywe ukuba khona kokugoba.

2. Ifomu lesango linganqunywa umkhiqizo. Kodwa ubukhulu kufanele bube bukhulu ngangokunokwenzeka, ingxenye eqondile yesango kufanele ibe mfushane ngangokunokwenzeka, futhi ubude bayo bungalawulwa phakathi kuka-0.5 ~ 1.0mm. Indawo yembobo yokuphakelayo kufanele isethwe odongeni oluwugqinsi.

3. Beka izimbobo ezibandayo ezanele ekugcineni kwe-sprue. Ngoba imikhiqizo ye-PSU, ikakhulukazi imikhiqizo enezindonga ezincane, idinga ingcindezi ephezulu yomjovo kanye nezinga lomjovo elisheshayo, izimbobo ezinhle zokukhipha umoya noma ama-grooves kufanele amiswe ukuze kukhishwe umoya esibunjeni ngesikhathi. Ukujula kwalawa ma-vent noma ama-grooves kufanele kulawulwe ngaphansi kuka-0.08mm.

4. Ukusetha izinga lokushisa kwesikhunta kufanele kube yinzuzo ukuthuthukisa ukuncibilika kwe-PSU ngesikhathi sokugcwaliswa kwefilimu. Izinga lokushisa lesikhunta lingafinyelela ku-140 ℃ (okungenani ku-120 ℃).
