Nkhani Zofunika Kuyang'ana kwa PPSU popanga jekeseni

PPSU, dzina la sayansi la polyphenylene sulfone resin, ndi amorphous thermoplastic yokhala ndi kuwonekera kwambiri komanso kukhazikika kwa hydrolytic, ndipo zinthuzo zimatha kupirira kupha tizilombo toyambitsa matenda mobwerezabwereza.

PPSU ndiyofala kwambiri kuposa polysulfone (PSU), polyethersulfone (PES) ndi polyetherimide (PEI).

Kugwiritsa ntchito PPSU

1. Zida zapakhomo ndi zotengera zakudya: zitha kugwiritsidwa ntchito kupanga zida za uvuni wa microwave, zotenthetsera khofi, zowumitsa, zowumitsira tsitsi, zotengera zakudya, mabotolo amwana, ndi zina zambiri.

2. Zogulitsa zamagetsi: m'malo mwa mkuwa, zinki, aluminiyamu ndi zitsulo zina, kupanga mawotchi owonetsera, zipangizo zokongoletsa mkati ndi zojambula zojambula, mbali za kamera ndi zigawo zina zomveka bwino.

3. Makina opanga makina: makamaka amagwiritsa ntchito magalasi owonjezera owonjezera, zinthuzo zimakhala ndi mawonekedwe a kukana kukwawa, kuuma, kukhazikika kwazithunzi, ndi zina zotero, zoyenera kupanga mabakiteriya onyamula ndi zigawo zamakina ndi zina zotero.

4. Zachipatala ndi zaumoyo: zoyenera kwambiri zida za mano ndi opaleshoni, mabokosi ophera tizilombo toyambitsa matenda (mbale) ndi zida zosiyanasiyana zosagwirizana ndi anthu.

PPSU mawonekedwe

Tinthu ting'onoting'ono tachilengedwe tokhala ngati tinthu tating'onoting'ono tokhala ngati tinthu tating'onoting'ono tomwe timaonekera.

Zofunikira pakuchita bwino kwa PPSU

Mfundo zingapo ziyenera kutsatiridwa popanga zinthu za PPSU ndi nkhungu

1. The fluidity ya PSU kusungunuka ndi osauka, ndi chiŵerengero cha kusungunuka otaya kutalika kwa khoma makulidwe ndi pafupifupi 80. Choncho, makulidwe khoma la mankhwala PSU sayenera kuchepera 1.5mm, ndipo ambiri a iwo ali pamwamba 2mm.

Zogulitsa za PSU zimakhudzidwa ndi notch, chifukwa chake kusintha kwa arc kuyenera kugwiritsidwa ntchito kumanja kapena pachimake. Kutsika kwapang'onopang'ono kwa PSU ndikokhazikika, komwe kuli 0.4% -0.8%, ndipo njira yosungunuka yosungunuka ndiyofanana ndi yolunjika. Ngodya yotsitsa iyenera kukhala 50: 1. Kuti mupeze zinthu zowala komanso zoyera, kuuma kwa nkhungu kumafunika kukhala oposa Ra0.4. Pofuna kuwongolera kusungunuka kwamadzi, sprue wa nkhungu amafunika kukhala waufupi komanso wandiweyani, m'mimba mwake ndi osachepera 1/2 ya makulidwe a chinthucho, ndipo ali ndi otsetsereka 3 ° ~ 5 °. Gawo la mtanda la shunt channel liyenera kukhala la arc kapena trapezoid kuti pasakhale ma bend.

2. Mawonekedwe a chipata amatha kutsimikiziridwa ndi mankhwala. Koma kukula kwake kuyenera kukhala kwakukulu momwe kungathekere, gawo lolunjika la chipata liyenera kukhala lalifupi momwe lingathere, ndipo kutalika kwake kumatha kuyendetsedwa pakati pa 0.5 ~ 1.0mm. Malo a doko la chakudya ayenera kukhazikitsidwa pa khoma wandiweyani.

3. Ikani mabowo ozizira okwanira kumapeto kwa sprue. Chifukwa zinthu za PSU, makamaka zokhala ndi mipanda yopyapyala, zimafunikira kupanikizika kwambiri kwa jakisoni komanso jekeseni mwachangu, mabowo abwino otulutsa mpweya kapena ma groove ayenera kukhazikitsidwa kuti azitha kutulutsa mpweya mu nkhungu munthawi yake. Kuya kwa zolowera izi kapena poyambira kuyenera kuyendetsedwa pansi pa 0.08mm.

4. Kuyika kwa kutentha kwa nkhungu kuyenera kukhala kopindulitsa kupititsa patsogolo kusungunuka kwa PSU kusungunuka panthawi yodzaza filimu. Kutentha kwa nkhungu kumatha kufika 140 ℃ (osachepera 120 ℃).
