極壓抗磨劑的常用種類，極壓抗磨劑是一種重要的潤滑脂添加劑，大部分是一些含硫、磷、氯、鉛、鉬的化合物。在一般情況下，氯類、硫類可提高潤滑脂的耐負(fù)荷能力，防止金屬表面在高負(fù)荷條件下發(fā)生燒結(jié)、卡咬、刮傷；而磷類、有機(jī)金屬鹽類具有較高的抗磨能力，可防止或減少金屬表面在中等負(fù)荷條件下的磨損。有機(jī)氯化物，有機(jī)氯化物在極壓條件下摩擦系數(shù)小，所賦予潤滑脂的極壓性能比抗磨性好，但在高溫和有水條件下極壓性能會下降。并引起金屬腐蝕和銹蝕，陜西tpv進(jìn)口。常用添加量為1%--10%，陜西tpv進(jìn)口。氯化石蠟是一種較古老的極壓添加劑產(chǎn)品，淺黃色至黃色粘稠液體，因含氯量不同又分為三種，陜西tpv進(jìn)口，氯化石蠟42，氯化石蠟50和氯化石蠟52。氯化石蠟加熱到120℃以上會緩慢分解，放出氯化氫氣體，所以經(jīng)常與金屬磺酸鹽類防銹劑共同使用。上海和氏璧化工公司TPV服務(wù)值得放心。陜西tpv進(jìn)口</p><div

聚甲醛樹脂是一種沒有側(cè)鏈、高密度、高結(jié)晶性的線型聚合物。由于新能源汽車的爆發(fā)性增長，在產(chǎn)能供應(yīng)方面出現(xiàn)了明顯的不足。短期內(nèi)供不應(yīng)求的狀況難以得到改善。聚甲醛樹脂價格近來有不斷上升的趨勢。下面我們一起來了解一下聚甲醛樹脂的性能和結(jié)構(gòu)。聚甲醛材料物理性質(zhì)：聚甲醛是高聚物，其結(jié)晶度相對較高，它的綜合力學(xué)性比起其它的塑料要好很多，比如它具有很高的強(qiáng)度、很高的硬度，其彈性模量更是比一般塑料大很多，它具有與金屬材料很接近的比強(qiáng)度和比剛度；聚甲醛材料的沖擊強(qiáng)度和疲勞強(qiáng)度相對較高、并擁有不錯的耐磨性。 </p> </p><p style="text-indent:25px"> 電子、電氣工業(yè)是硅橡膠作為絕緣材料使用早,需求量較大的一個領(lǐng)域。硅橡膠主要用于電視機(jī)陽極罩、高壓保護(hù)罩、高壓引出線、冰箱除霜器電線、功率或訊號傳遞用電線和電纜等。用硅橡膠制造的絕緣子將替代陶瓷制品用于輸電線路,特別是超高壓線路。導(dǎo)電硅橡膠用于電子計算機(jī)、電話等儀器的電接點件及液晶顯示觸點件。阻燃和耐輻射硅橡膠制造的電線、電纜用于原子能發(fā)電站。硅橡膠加熱片、加熱帶用于控制多種精密儀表和輸油管道的工作溫度,在醫(yī)療上作理療熱敷器用的加熱毯。室溫硫化型硅橡膠可作為防水、防潮和防震用灌封材料。上海和氏璧化工公司是一家專業(yè)提供TPV的公司，有想法可以來我司咨詢！</p><div

微細(xì)化是滑石產(chǎn)品發(fā)展趨勢，產(chǎn)品越細(xì)，其增果越好，但同時粒子的表面能增大，容易團(tuán)聚，分散困難，價格也高。因此需要根據(jù)自身的技術(shù)水平和實際需要來選擇適當(dāng)細(xì)度的產(chǎn)品，并不一定越細(xì)越好。值得注意的是，滑石粉由于其本身的片狀結(jié)構(gòu)，比表面積大，體積密度較小。325目滑石粉的體積密度為0.8-0.9g/cm3，1250目滑石粉卻降到了0.25-0.3g/cm3，4000目*有0.12g/cm3左右。這使使用時粉塵污染嚴(yán)重、混料困難、成本提高、產(chǎn)率下降。而且遠(yuǎn)距離供貨的運(yùn)費(fèi)成本相當(dāng)高。上海和氏璧化工公司致力于提供TPV，歡迎新老客戶來電！北京TPV牌號齊全</p><p
