石蠟（Paraffin）是從石油、頁(yè)巖油或其他瀝青礦物油的某些餾出物中提取出來(lái)的一種烴類混合物，主要成分是固體烷烴，無(wú)臭無(wú)味，為白色或淡黃色半透明固體。石蠟是不同分子量的正鏈飽和烷烴的混和物，可用通式CnH2n+2表示。按照石蠟的物理狀態(tài)，可以分為液體石蠟、固體石蠟和微晶蠟三大類。石蠟具有價(jià)格低廉、來(lái)源***、無(wú)色無(wú)味、理化性能穩(wěn)定、較大的相變潛熱等諸多優(yōu)點(diǎn)，因此***地應(yīng)用于醫(yī)藥、包裝、建筑、***偽裝、工業(yè)和農(nóng)業(yè)等領(lǐng)域，近年來(lái)在復(fù)合相變儲(chǔ)能材料上有很多的研究。理化性質(zhì)外觀為白色固體。熔點(diǎn)50℃～70℃，相對(duì)密度，平均碳鏈長(zhǎng)為C28～C29，相對(duì)平均分子質(zhì)量為400的品種：20℃固體相對(duì)密度～，折射率～，100℃液體相對(duì)密度～，折射率～。溶于苯、氯仿、四氯化碳、樟腦油，不溶于甲醇、乙醇和水。性能指標(biāo)1.熔點(diǎn)石蠟是烴類的混合物，因此它并不像純化合物那樣具有嚴(yán)格的熔點(diǎn)。所謂石蠟的熔點(diǎn)，是指在規(guī)定的條件下，冷卻熔化了的石蠟試樣，當(dāng)冷卻曲線上***次出現(xiàn)停滯期的溫度。各種蠟制品都對(duì)石蠟要求有良好的耐溫性能，即在特定溫度不熔化或軟化變形。按照使用條件、使用的地區(qū)和季節(jié)以及使用環(huán)境的差異，要求商品石蠟具有一系列不同的熔點(diǎn)。 美國(guó)史東畢斯公司STRAHL & PITSCH, INC. 固體石蠟 Paraffin Wax, SP-1275,NF.安徽史東畢斯輔料巴西棕櫚蠟SP63ORG
Strahl & Pitsch offers an extensive range of the finest food-grade Paraffin waxes from domestic and international sources. Paraffin waxes come from the de-waxing of paraffin distillates. Paraffin waxes have relatively large, brittle crystals (Macro crystalline) and generally have little affinity for oil.
