Chneure polurethane buffer ndi chida chotetezera chomwe chimagwiritsa ntchito zida za polyurethane, zinthu za polymer, kuti zichotse mphamvu ndikusiya mphamvu yaku Kineetic yosunthira. Nthawi zambiri imakhazikitsidwa kumapeto kwa njanji ya crane, malo owomberapo gawo, kapena madera ena pomwe kuwombana kumatha kuchitika. Cholinga chake ndikutenga mphamvu kugundana, sinthani mphamvu, kuteteza crane ndi njanji, ndikuchepetsa phokoso.
Kugwiritsa ntchito mabizinesi ofala a polyirethane kumachitika chifukwa cha zabwino zake zingapo:
1. Mafuta otsatsira mphamvu kwambiri: ma polyerethane obzala amatha kuyamwa mphamvu zochulukirapo pamagetsi, zomwe zimapangitsa kuti pakhale kuthamanga kwambiri.
2. Kutalika Kwakukulu Kwambiri: Chrore polurethane buffers kumatha kupirira katundu wapamwamba ndipo ndioyenera ma cranes olemera.
3. Voteke ndi kukalakana: Zinthu zabwino za polyirethaine zimatha kukana, kukana mafuta, ndikukakamizidwa kwa ozoni, chifukwa cha ntchito yayitali.
4. Wopepuka komanso wosavuta kukhazikitsa: Poyerekeza ndi zitsulo zachitsulo, zimakhala zopepuka kwambiri, kusungitsa ntchito ndi kukhazikitsa.
5.
6. Kusinthidwa kwakukulu kwa mitundu: nthawi zambiri amakhalabe ndi magwiridwe antchito ambiri kuyambira -35 ° C kwa + 80 ° C.
7. Kusaka-kwaulere: Pansi pa ntchito wamba, mosiyana ndi zonunkhira za hydraulic, sizifunikira mafuta a hydraulic ndipo ndizopanda chitetezo.
8. Ubwino wokwera mtengo kwambiri: Kuganizira zomwe zagulira kwathunthu, kukhazikitsa, ndi kukonza ndalama, amapereka phindu labwino ndalama.
Maonekedwe owoneka a polyirethane amagwiritsidwa ntchito kwambiri m'magulu osiyanasiyana kukweza ndi makina okwera njanji:
