Zisindikizo za PU

Mphete yotsekera ya polyurethane imadziwika ndi kukana kuvala, mafuta, asidi ndi alkali, ozoni, ukalamba, kutentha kochepa, kung'ambika, kukhudzidwa, ndi zina zotero. Mphete yotsekera ya polyurethane ili ndi mphamvu yayikulu yothandizira katundu ndipo imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana. Kuphatikiza apo, mphete yotsekera yopangidwa ndi cast silinda ndi yolimba, yolimba ndi hydrolysis, yolimba, ndipo ili ndi mphamvu zambiri, yomwe ndi yoyenera zida zamafuta opanikizika kwambiri, zida zonyamulira, zida zamakina opangira, zida zazikulu za hydraulic, ndi zina zotero.

Mphete yosindikizira ya Polyurethane: polyurethane ili ndi mphamvu zabwino kwambiri zamakanika, ndipo kukana kwake kutopa ndi kukana kuthamanga kwambiri ndikwabwino kwambiri kuposa ma rabara ena. Kukana kukalamba, kukana ozone ndi kukana mafuta nazonso ndizabwino, koma n'zosavuta kusungunuka ndi hydrolyze kutentha kwambiri. Nthawi zambiri imagwiritsidwa ntchito polumikiza zomangira zomatira zolimba komanso zolimba, monga ma silinda a hydraulic. Nthawi zambiri, kutentha kwake ndi - 45~90 ℃.

Kuwonjezera pa kukwaniritsa zofunikira zonse zogwiritsira ntchito mphete yotsekera, mphete zotsekera za polyurethane ziyeneranso kulabadira zinthu zotsatirazi:

(1) Yodzaza ndi kusinthasintha komanso kulimba mtima;

(2) Mphamvu yoyenera ya makina, kuphatikizapo mphamvu yokulirapo, kutalika kwake ndi kukana kung'ambika.

(3) Kugwira ntchito kokhazikika, kovuta kutupa pakati, komanso kuchepa pang'ono kwa kutentha (Joule effect).

(4) Ndi yosavuta kuikonza ndi kuipanga, ndipo imatha kusunga kukula kolondola.

(5) Sizimawononga malo olumikizirana ndi kuipitsa malo olumikizirana.

Ningbo Yokey Automotive Parts Co., Ltd imayang'ana kwambiri kuthetsa mavuto a zinthu za rabara za makasitomala ndikupanga mitundu yosiyanasiyana ya zinthu kutengera momwe zinthuzo zimagwiritsidwira ntchito.
