黃石鐵山-大冶市美孚壓縮機(jī)油-導(dǎo)熱油質(zhì)量銷售烷基苯型（苯環(huán)型）導(dǎo)熱油：屬于短支鏈烷烴基（包括甲基、乙基、異丙基）與苯環(huán)結(jié)合的產(chǎn)物。其沸點(diǎn)在170~180℃，凝點(diǎn)在-80℃以下，故可做防凍液使用。 烷基萘型導(dǎo)熱油：其附加側(cè)鏈的種類及數(shù)量決定化合物的性質(zhì)。側(cè)鏈單于甲基相連的烷基萘，應(yīng)用于240~280℃范圍的氣相加熱系統(tǒng)。 烷基聯(lián)苯型導(dǎo)熱油：是由短鏈的烷基（乙基、異丙基）與聯(lián)苯環(huán)相結(jié)合構(gòu)成，烷基的種類和數(shù)量決定其性質(zhì)。烷烴基數(shù)量越多，其熱穩(wěn)定性越差。 聯(lián)苯和聯(lián)苯醚低熔混合物型導(dǎo)熱油：此類產(chǎn)品因?yàn)楸江h(huán)上沒有與烷烴基側(cè)鏈連接，而在有機(jī)熱載體中耐熱性。這種凝點(diǎn)（12.3℃）低熔混合物，在常溫下，沸騰溫度在256~258℃范圍內(nèi)使用比較經(jīng)濟(jì)。 烷基聯(lián)苯醚型導(dǎo)熱油：此類混合導(dǎo)熱油低溫下運(yùn)動(dòng)粘度低，流動(dòng)性好，適合北方寒冷地區(qū)使用，使用溫度不超過330℃，凝點(diǎn)-54℃。 礦物型導(dǎo)熱油：是石油精制過程某一餾程產(chǎn)物，其主要成分隨基礎(chǔ)油的成分不同。一般為長鏈烷烴和環(huán)烷烴的混合物。Alkylbenzene type (benzene ring type) heat transfer oil: It belongs to the product of short branc alkyl groups (including methyl, ethyl, isopropyl) combined with benzene rings. Its boiling point is between 170~180℃, its freezing point is below -80℃, so it can be used as antifreeze. Alkylnaphthalene type heat transfer oil: The type quantity of the additional side chain determine the properties of the compound. Alkylnaphthalene with a side chain single to methyl is applied to gas phase heating systems in the range 240~280℃. Alkylbiphenyl type heat transfer oil: It is composed of short-chain alkyl groups (ethyl isopropyl) combined with biphenyl rings. The type and quantity of alkyl groups determine their properties. The more the number of alkyl groups, the worse thermal stability.
