PU zizindikiro

Polyurethane kusindikiza mphete yodziwika ndi kuvala kukana, mafuta, asidi ndi alkali, ozoni, ukalamba, kutentha otsika, kung'ambika, zimakhudza, etc. Polyurethane kusindikiza mphete ali ndi katundu waukulu kuthandiza mphamvu ndipo chimagwiritsidwa ntchito m'madera osiyanasiyana. Kuphatikiza apo, mphete yosindikiza ya cast imalimbana ndi mafuta, imalimbana ndi hydrolysis, yosavala, ndipo ili ndi mphamvu zambiri, yomwe ili yoyenera zida zamafuta apamwamba, zida zonyamulira, zida zamakina, zida zazikulu zama hydraulic, ndi zina zambiri.

Mphete yosindikizira ya polyurethane: polyurethane ili ndi mawonekedwe abwino kwambiri amakina, ndipo kukana kwake kuvala komanso kukana kuthamanga kwambiri ndizopambana kwambiri kuposa ma rubber ena. Kukana kukalamba, kukana kwa ozoni ndi kukana kwamafuta kulinso kwabwino, koma ndikosavuta kuyimitsa hydrolyze kutentha kwambiri. Nthawi zambiri amagwiritsidwa ntchito polumikizana ndi ma hydraulic cylinders omwe samva kuthamanga kwambiri komanso osamva kuvala. Nthawi zambiri, kutentha ndi -45 ~ 90 ℃.

Kuphatikiza pakukwaniritsa zofunikira zonse pakusindikiza mphete, mphete zosindikizira za polyurethane ziyeneranso kulabadira izi:

(1) Wodzaza ndi kusinthasintha ndi kupirira;

(2) Mphamvu yoyenera yamakina, kuphatikiza mphamvu yakukulitsa, kutalika ndi kukana misozi.

(3) Kuchita kokhazikika, kovuta kutupa pakati, ndi kuchepa kwazing'ono kwa kutentha (Joule effect).

(4) Ndi yosavuta kuyikonza ndi kuumba, ndipo imatha kusunga kukula kwake.

(5) Simawononga malo olumikizana ndikuipitsa sing'anga.

Ningbo Yokey Automotive Parts Co., Ltd imayang'ana kwambiri kuthana ndi zovuta zamakasitomala zakuthupi ndikupanga mapangidwe osiyanasiyana azinthu kutengera zochitika zosiyanasiyana zogwiritsira ntchito.
