Polyurethane sealing nplhaib yog tus cwj pwm los ntawm kev hnav tsis kam, roj, acid thiab alkali, ozone, kev laus, tsis tshua muaj kub, tearing, cuam tshuam, thiab lwm yam. Polyurethane sealing nplhaib muaj peev xwm txhawb nqa loj thiab siv dav hauv ntau yam. Tsis tas li ntawd, cam khwb cia sealing nplhaib yog roj resistant, hydrolysis resistant, hnav-tiv taus, thiab muaj lub zog siab, uas yog tsim rau cov khoom siv roj siab, lifting khoom, forging tshuab cuab yeej, cov khoom siv hydraulic loj, thiab lwm yam.
Polyurethane foob nplhaib: polyurethane muaj cov khoom siv zoo heev, thiab nws cov kev hnav tsis kam thiab kev kub siab ua haujlwm zoo dua li lwm cov roj hmab. Kev laus tsis kam, ozone kuj thiab roj kuj tseem zoo heev, tab sis nws yooj yim rau hydrolyze ntawm qhov kub thiab txias. Nws feem ntau yog siv rau kev kub siab resistant thiab hnav-resistant sealing txuas, xws li hydraulic kheej kheej. Feem ntau, qhov kub thiab txias yog -45 ~ 90 ℃.
Ntxiv rau qhov ua tau raws li cov kev cai dav dav rau cov khoom siv sib khi, polyurethane sealing rings yuav tsum tau them sai sai rau cov xwm txheej hauv qab no:
(1) Tag nrho ntawm elasticity thiab resilience;
(2) Tsim nyog txhua yam muaj zog, suav nrog lub zog nthuav dav, elongation thiab tsim kua muag.
(3) Kev ua haujlwm ruaj khov, nyuaj rau o hauv nruab nrab, thiab cov nyhuv thermal shrinkage me me (Joule effect).
(4) Nws yog ib qho yooj yim rau kev ua thiab cov duab, thiab tuaj yeem tswj tau qhov loj me.
(5) Nws tsis corrode qhov chaw tiv tauj thiab ua paug qhov nruab nrab.
Ningbo Yokey Automotive Parts Co., Ltd tsom rau kev daws cov neeg siv khoom 'cov teeb meem ntawm cov khoom siv roj hmab thiab tsim cov ntaub ntawv sib txawv raws li qhov sib txawv ntawm daim ntawv thov scenarios.
