style="text-indent:25px">曉得橡膠O型圈的溝槽尺度，怎么挑選O型圈尺度。溝槽的尺度：槽底直徑，槽寬，槽深等數(shù)據(jù)。斷定O型圈尺度，如果是靜密封，那通常能夠這樣來承認(rèn)：槽底直徑/1.04(拉伸率按4%核算）=O型圈內(nèi)徑；槽深*1.2（緊縮率按20%核算）=O型圈線徑；思考到緊縮后O型圈截面會(huì)變型鋪開，槽寬通常為線徑的1.3倍左右。當(dāng)然需視密封的工況歸納思考，只能說大體是這樣。別的還有動(dòng)密封，旋轉(zhuǎn)密封，往復(fù)密封，軸向密封，徑向密封等等。噴霜現(xiàn)象在橡膠O型圈成型后常出現(xiàn)，那么噴霜現(xiàn)象到底是什么呢？有什么危害呢？噴霜指液態(tài)或固態(tài)橡膠化合物成分從內(nèi)部到表面的現(xiàn)象遷移。常見的形式上有“噴粉”、“噴油”和“噴蠟”?！皣姺邸笔窍鹉z化合物硫化劑，促進(jìn)劑，活性劑，抗氧化劑，填料和其它成分沉淀橡膠粉末（或硫化橡膠）表面，形成類似霜層的層;噴蠟是塑料蠟的蠟添加劑化合物表面層淀積膜;橡膠化合物是注射柔軟劑，潤滑劑，增塑劑和沉積表面形成一層油其他液體組分。由于技術(shù)的落后，國產(chǎn)橡膠密封圈產(chǎn)品只能盡力在中低端商場(chǎng)分上一杯羹。山東耐磨損橡膠O型圈生產(chǎn)廠家</p><p
