Ma polyurethane Extruded Parts

Ma polyurethane extruded part ndi zinthu zophatikizika zopangidwa kuchokera ku utomoni wa polyurethane monga matrix azinthu ndikukonzedwa kudzera muukadaulo wa extrusion. Chigawo chake chachikulu chagona pakuphatikizika kwa magwiridwe antchito abwino kwambiri a polyurethane komanso ukadaulo wapamwamba wa extrusion, womwe umagwiritsidwa ntchito kwambiri m'magawo monga zomangamanga, zoyendera, ndi makina.

1.Mechanical katundu

• Mphamvu yayikulu: Mphamvu zamakokedwe nthawi zambiri zimakhala pamwamba pa 50MPa, ndipo mphamvu yopindika imatha kufikira 50-75MPa, yomwe ingalowe m'malo mwazitsulo zachikhalidwe ndi aluminiyamu.
• Opepuka: yokhala ndi kachulukidwe kakang'ono kuposa zitsulo ndi ma aluminiyamu aloyi, imakhala ndi ndalama zochepa zoyendera ndi kukhazikitsa. pa

2.Kukana kwa dzimbiri

• Acid alkali mchere: akhoza kukana ambiri asidi, zamchere, mchere ndi organic dzimbiri, oyenera madera m'mphepete mwa nyanja ndi chinyezi.
• Kukaniza kwamafuta: Imakhala ndi kukana bwino kwamafuta osiyanasiyana ndipo ndiyoyenera kusindikiza monga zisindikizo zamafuta. pa

3.Insulation ndi ntchito yotsekemera yotentha

• Low matenthedwe madutsidwe: The matenthedwe madutsidwe kutentha firiji ndi 0.22W/m • k, amene ndi pafupifupi 1/700 aloyi zotayidwa ndi oyenera kutchinjiriza zipangizo.
• Coefficient yotsika ya kukula kwamafuta amtundu: Mofanana ndi zida zapakhoma, sikophweka kutulutsa mipata pamene kusiyana kwa kutentha kumasintha. pa

4.Kupanga ndondomeko

• Kuthamanga: Kuthamanga kwa extrusion kumatha kufika 0.6-2.0m / min, yomwe ndi 2-5 nthawi zambiri kuposa zipangizo zamakono.
• Chitetezo Chachilengedwe: Njira yopangira zinthu imakhala yosungunulira-yaulere ndipo imakwaniritsa zofunika pakupanga zobiriwira. pa

5. Zochitika zogwiritsira ntchito

• Zomangamanga: Zogwiritsidwa ntchito pazinthu monga mafelemu a zitseko ndi mazenera, makoma a makatani, ndi zina zotero, kuchepetsa kulemera kwa nyumba ndi kupititsa patsogolo kutsekemera kwa mawu. pa
• Mayendedwe: Kupanga zida zamagalimoto ndi sitima kuti muchepetse kulemera kwa thupi ndikuwonjezera moyo wautumiki.
• Infrastructure: Amagwiritsidwa ntchito pothandizira zigawo za milatho ndi tunnel kuti zikhale zolimba.

Polyurethane (PU mwachidule) ndi mtundu wa pulasitiki wa polyurethane womwe uli ndi zinthu zambiri zothandiza, kuphatikiza kukhazikika, kuwonekera, kukana mafuta, kukana mafuta, komanso kukana kuvala. Kunena mwaukadaulo, ndi ma thermoplastic elastomer opangidwa ndi ma linear block copolymers a magawo olimba komanso ofewa.

Zogulitsa zathu zili ndi zabwino, magwiridwe antchito apamwamba, komanso mitengo yotsika mtengo. Titha kusintha ndikusintha magawo osiyanasiyana opangidwa ndi jakisoni wa PU malinga ndi zojambula zamakasitomala kapena zitsanzo.

1. Amagwiritsidwa ntchito ngati mafakitale osatha kuvala kwambiri,{1}}zotsekera mwamphamvu komanso zinthu za rabara, monga hydraulic cylinder sealing.

2. Zida zosiyanasiyana ndi kuuma kulipo kuti musankhe. Mutha kutipatsa zitsanzo kapena zojambula, ndipo tidzakupatsani zinthu zabwino kwambiri.
