抗磨性好壞跟金屬機(jī)體有關(guān)系。如對(duì)鋼材質(zhì)的潤(rùn)滑，加入硫磷添加劑的潤(rùn)滑油抗極壓效果一般，在含氯添加劑的油中抗極壓性能好。50號(hào)碳鋼材質(zhì)，含磷添加劑的潤(rùn)滑油抗壓效果一般，在含氯和硫添加劑的油中抗極壓性能好。45#鋼材質(zhì)，含磷硫添加劑的潤(rùn)滑油抗壓效果一般，在含氯添加劑的油中抗極壓性能好。鎘鎳鉬合金鋼材質(zhì)，含磷氯添加劑的潤(rùn)滑油抗壓效果一般，在含硫添加劑的油中抗極壓性能好。而硼酸鹽添加劑對(duì)上述的所有材質(zhì)抗極壓性能都很好。硼酸鹽添加劑一般不會(huì)造成金屬的腐蝕，而含磷硫氯的極壓添加劑，若配制的不好，往往造成金屬的腐蝕。硼酸鹽也基本沒(méi)有什么毒性。

style="text-indent:25px">使用優(yōu)點(diǎn)如下：抗磨極壓效果好，特別是在低粘度油中具有良好的抗磨極壓效果。有節(jié)能油的齒輪油，就是低粘度油加含硼添加劑制成，滿足了抗磨極壓性的要求。硼酸鹽極壓劑使用壽命長(zhǎng)，其作用機(jī)理是由滲硼形成的FexBy形式的極壓膜，這一層表面膜有較高硬度，良好的抗磨性，較好的抗氧化性、耐腐蝕性。而含硫磷氯活潑元素的極壓性，作用機(jī)理主要是活潑元素同金屬起化學(xué)反應(yīng)生成一層膜，這層膜的抗剪切強(qiáng)度比基礎(chǔ)金屬低，因此在使用過(guò)程中，這層膜很容易被磨掉，這樣添加劑消耗的比硼酸鹽要快。</p><p> 潤(rùn)滑油在我們的日常生活中隨處可見。機(jī)械設(shè)備的正常運(yùn)轉(zhuǎn)離不開潤(rùn)滑油。性能優(yōu)良的潤(rùn)滑油品可以充分潤(rùn)滑機(jī)械設(shè)備，減少摩擦和磨損、降低能源消耗、提高機(jī)械效率、延長(zhǎng)機(jī)械設(shè)備使用壽命。據(jù)估計(jì)，大約30%的能源消耗在摩擦上，80%的零件損壞是由磨擦磨損導(dǎo)致的。因此，提高油品潤(rùn)滑性能以減少摩擦、磨損和防止燒結(jié)對(duì)國(guó)民經(jīng)濟(jì)具有重要意義。潤(rùn)滑油品中通常通過(guò)引入極壓抗磨劑來(lái)改善基礎(chǔ)油摩擦學(xué)性能、減少摩擦副之間的摩擦阻力、降低磨損和擦傷，較終達(dá)到提高潤(rùn)滑油承載的目的。有的抗磨劑以石墨為主要原料，石墨雖然具有良好的抗磨性能，但容易集結(jié)，在發(fā)動(dòng)機(jī)內(nèi)部使用容易產(chǎn)生積炭。</p><div

汽車抗磨劑是一種高科技的機(jī)油(潤(rùn)滑油)添加劑，含金屬成分(納米顆粒)，可以降低發(fā)動(dòng)機(jī)磨損、增加發(fā)動(dòng)機(jī)功率，所以又稱為發(fā)動(dòng)機(jī)養(yǎng)護(hù)劑或強(qiáng)力修復(fù)劑，能延長(zhǎng)機(jī)油的使用壽命，節(jié)省燃油。首先，質(zhì)量的抗磨劑比普通機(jī)油粘附力更強(qiáng)，更耐熱、耐腐蝕，可稱附在汽缸內(nèi)壁形成一層保護(hù)膜，增強(qiáng)潤(rùn)滑效果，并修復(fù)汽缸內(nèi)壁的劃痕，讓粗糙的表面光滑，保證發(fā)動(dòng)機(jī)正常高速運(yùn)轉(zhuǎn)，起到養(yǎng)護(hù)和修復(fù)作用。其次，抗磨劑還有清潔作用，可以溶解汽缸內(nèi)多余的燃油、雜質(zhì)和積炭，使汽缸內(nèi)的高溫、高壓油氣充分燃燒，而不帶其他雜質(zhì)。關(guān)于抗磨劑的使用。在每次換完機(jī)油后，啟動(dòng)發(fā)動(dòng)機(jī)，趁熱每次可添加1瓶抗磨劑。平時(shí)汽車行駛8000km必須更換、添加一次機(jī)油，否則會(huì)把汽缸燒壞、冒藍(lán)，而加入質(zhì)量抗磨劑后，可8000km-12000km換一次機(jī)油，不僅節(jié)省了機(jī)油和發(fā)動(dòng)機(jī)保養(yǎng)的費(fèi)用，而且它還能提高汽油和柴油燃燒效果，節(jié)能4%一7%。上?？鼓┯杏脝?/p><p
