（1）二硫化鉬機(jī)油添加劑。二硫化鉬具有與石墨相似的層狀結(jié)構(gòu)（但不易集結(jié)），有很低的摩擦系數(shù)和較好的潤滑性能。被譽(yù)為“高級(jí)固體潤滑油王”。 </p> <p> 經(jīng)**機(jī)構(gòu)檢測(cè)，二硫化鉬是非常好的的干式潤滑劑，其形成的保護(hù)膜對(duì)寒冷季節(jié)車輛的冷起動(dòng)有很好的保護(hù)作用。 </p> <p> （2）陶瓷抗磨劑。陶瓷抗磨劑可吸附在金屬表面形成長效抗磨層，其保護(hù)能力可長達(dá)5萬km，因此不必每次更換機(jī)油時(shí)都添加。其薄片狀的類石墨結(jié)構(gòu)能減少摩擦和磨損，并且防止運(yùn)動(dòng)部件的直接接觸。<0.5μm的微粒尺寸保證了理想的過濾流動(dòng)性，并且防止了固體潤滑顆粒的沉積。上?？鼓?shí)驗(yàn)陶瓷抗磨劑薄片狀的類石墨結(jié)構(gòu)能減少摩擦和磨損，并且防止運(yùn)動(dòng)部件的直接接觸。</p><div

市面上出現(xiàn)了各種發(fā)動(dòng)機(jī)機(jī)油抗磨劑，主要目的是減少發(fā)動(dòng)機(jī)的磨損。從理論描述的形式上都是形成保護(hù)層，宣稱節(jié)油，升動(dòng)力，減少排放污染。那么多的抗磨劑品牌到底有用嗎？ </p> <p> <br /> </p> <p> <br /> </p> <p> 如果從單一的減緩磨損角度來說，有些抗磨劑是有用的。

對(duì)于一個(gè)單一作用的抗磨劑來說，在解決了磨損的同時(shí)，卻無法顧及其他的保護(hù)需求，甚至自身在高溫高壓下所產(chǎn)生的化學(xué)和物理反應(yīng)，會(huì)對(duì)其他系統(tǒng)和部件造成不良影響，比如形成積碳，增大噪音，減少機(jī)濾壽命，縮短機(jī)油更換周期等等。 </p> <p> 抗磨劑只是抗磨，發(fā)動(dòng)機(jī)保護(hù)所需要的不僅僅是抗磨！ </p><p> 由于六方氮化硼具有類似石墨的層狀結(jié)晶結(jié)構(gòu)，所以六方氮化硼也和石墨一樣，具有很好的潤滑性，和石墨潤滑劑相比較，六方氮化硼雖然價(jià)格偏高，但如下圖所示，石墨在使用溫度超過400度的時(shí)候，石墨的潤滑性能，將會(huì)急劇下降，但六方氮化硼在600℃時(shí)，摩擦系數(shù)仍然維持在0.2左右，潤滑性能受溫度的影響很小，所以可以看出六方氮化硼特別適用于高溫環(huán)境，并且HBN的顏色為白色，干凈且環(huán)保。由于現(xiàn)在市場上抗磨劑良莠不齊、魚龍混雜，有些抗磨劑加到機(jī)油里不僅不會(huì)有良好的抗磨作用，甚至還有的還會(huì)產(chǎn)生副作用，所以有些知名汽車品牌如奔馳、寶馬、奧迪，或是知名潤滑油品牌聲稱不許消費(fèi)者在機(jī)油額外適用添加劑，筆者覺得這樣固然可以防止一些不良產(chǎn)品對(duì)消費(fèi)者產(chǎn)生危害，但也不宜“一刀切”，對(duì)一些正規(guī)渠道銷售的、原裝進(jìn)口的、有一定知名度的抗磨產(chǎn)品我們還是提倡可以正確使用，這樣也對(duì)消費(fèi)者的愛車提供一份額外的保護(hù)，豈不更好？ </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 防凍液的沸點(diǎn)，一般防凍液的沸點(diǎn)是108℃左右，但有的發(fā)動(dòng)機(jī)溫度可以到110℃，應(yīng)該選擇沸點(diǎn)高一點(diǎn)的防凍液。</p><div style="width:100%;text-align: center;"><img

</p> <p> 6、飲用酒試驗(yàn)：按一定比例加入任意飲用酒中，檢查溶液的ph值，三性均衡的抗磨添加劑ph值應(yīng)該在7左右。 </p> <p> 7、價(jià)格過低者慎重：如325ml瓶裝，售價(jià)不足10元，多為稀釋過的增粘劑(成品增粘劑一般8000-9000元/噸)，或本身就是高級(jí)別機(jī)油。 </p> <p> 現(xiàn)在國外大添加劑公司推出的高級(jí)別的內(nèi)燃機(jī)油復(fù)合添加劑(如SL、SM、CI-4)多加有有機(jī)鉬、有機(jī)硼抗磨節(jié)能劑，再額外加入抗摩劑更容易造成三大特性的均衡性的破壞。所以，抗磨減摩劑在內(nèi)燃機(jī)成品油中額外使用更要謹(jǐn)慎。抗磨劑的目的就是減少發(fā)動(dòng)機(jī)的磨損，但是為了追求抗磨而無法兼顧其他高溫高壓的需求。上海優(yōu)質(zhì)極壓抗磨劑</p><p

1、聞味：發(fā)動(dòng)機(jī)需要的是“溫和的”三性均衡的抗磨添加劑，常溫下，該類劑幾乎無刺激味、無不愉快味，按一定比例加入機(jī)油，攪均加熱100度以上，也沒有刺激味、無不愉快味。 </p> <p> 2、顏色：顏色不決定質(zhì)量，不同組成與結(jié)構(gòu)的抗磨減摩劑顏色差異是很大的，可以無色，也可以是淺黃色、綠色、黑綠色。<br /> <p> 3、油溶解性：按一定比例加入機(jī)油，攪均加熱50-60度左右，用大試管觀察，不管顏色多深，應(yīng)該透明，不混濁，放置幾天，也不出現(xiàn)沉淀。 </p> <p> 4、摩擦試驗(yàn)：用市場上流行的小型試驗(yàn)機(jī)試驗(yàn)，在一定負(fù)荷下運(yùn)轉(zhuǎn)，觀察油品10幾分鐘后的溫度變化和磨塊磨斑大小。溫度低、磨斑小的比較好。 </p>
