Momwe mungayang'anire ndi kukonza zisindikizo za polyurethane ndi katundu wabwino kwambiri?

Zisindikizo za polyurethane zimapangidwa kuchokera ku mphira wokhala ndi zinthu zotsatirazi:

Zisindikizo za polyurethane zimakhala ndi elasticity yabwino, kukana kuvala, kukana mafuta, kukana kuzizira komanso kulimba kwamphamvu, koma kukana madzi, makamaka kukana kwa alkali, ndikosauka.Amapezeka mu kutentha kwa vulcanised, kutentha kwa chipinda vulcanised ndi mitundu yotentha yosungunuka.The chipinda kutentha vulcanization mtundu wagawidwa mu chigawo chimodzi ndi awiri chigawo.Amagwiritsidwa ntchito kwambiri posindikiza zinthu m'nyumba komanso kusindikiza pakupanga magalimoto.

Kuzindikira ndi kukonza mphete za polyurethane O (zisindikizo): fufuzani kuti zida zowongolera ma hydraulic zilibe vuto, ndipo ntchito yokonza imalowa m'malo osawona kwakanthawi.Disassemble ndi fufuzani yamphamvu kotalika wa chofukizira chida, anapeza kuti pisitoni mafuta chisindikizo "O" chisindikizo akunja bwalo wakhala pansi lathyathyathya, pa nthawi yomweyo anapeza kuti pisitoni bwalo akunja kukula sakukwaniritsa zofunika (makina chida kupanga zifukwa) , m'mimba mwake malangizo ndi zosakwana kukula muyezo 0.8MM, pisitoni ndi yamphamvu thupi chilolezo ndi lalikulu kwambiri, chifukwa utali yamphamvu awiri patsekeke kusinthana mafuta.Kusamalira pamene kusinthidwa kwa pistoni yoyenerera ndi "O-type" zisindikizo pambuyo pa chida cha makina nkhonya kuthetsa mavuto.Kuwunika kwa chifukwa chake kuli mu chimango cha mpeni pansi pa mpeni pakali pano, chimango cha mpeni chonse ndi chisonkhezero, chikhoza kuthyoledwa mu chikhalidwe chake chokakamiza, kuthamanga kwa valve yobwereranso, mphamvu ya dera lamphamvu. .
