  • 橡胶硫化剂:硫磺在橡胶硫化剂中占首要地位,其价格低廉,应用广泛。适用于天然橡胶和二烯类合成橡胶。在软质橡胶制品中,一般用量为0.3~4份;在硬质制品中的用量 一般为 30~60份。硫化时需配合硫化促进剂和促进助剂(如活性剂)。酸会迟延硫化,故硫磺中不应含酸。硫磺在胶料中的溶解度随胶种而异,温度升高,溶解度增大。用量过多时,易发生喷硫,影响制品的老化性能和其它物理性能。对于未硫化胶料来说,喷硫还会破坏硫磺在胶料中的分布均匀性,降低表面粘着力,给加工造成困难。为防止未硫化胶的喷硫,硫磺宜在低温下混入。加硫磺之前先加入软化剂、使用槽法炭黑、掺入再生胶等均能减少喷硫现象。采用不溶性硫磺也是消除喷硫的主要方法。 胶工业中使用的硫磺主要有六种: 1,硫磺粉:由精制块状硫磺经粉碎筛选而得。是橡胶最主要的硫化剂。 2,沉淀硫磺:在橡胶中的分散性好。适用于高级制品及胶乳薄膜制品等。 3,胶体硫磺:将硫磺粉或沉淀硫磺与分散剂一起在球磨机或胶体磨中研磨,制成糊状物即为胶体硫,也可干燥成固体状物。粒子极细,粒径1~3μm。主要用于胶乳制品,分散均匀,沉降速度慢。 4,不溶性硫磺:因本品不溶于二硫化碳,故称不溶性硫磺。本品在硫化前的加工操作温度下不溶于胶料,在硫化温度下溶于胶料而发挥硫化作用。可防止混炼胶喷硫、粘着性下降等弊害。也不易产生早期硫化现象。适用于钢丝帘线轮胎等重要的橡胶制品,用量与普通硫磺相同。 5,表面处理硫磺:将粉末硫磺或沉淀硫磺用对硫化无影响的处理剂(如聚异丁烯等)进行表面附着处理而得。其特点是混炼容易,分散性好,焦烧性小,操作安全性大。 6,硫磺混合物:由硫磺粉与聚合物或其它添加剂混合而成。其目的是改善硫磺的分散性,防止硫磺凝集结晶等。
  • 方法三:火山型自然硫矿床一般用露天开采法,沉积型和盐丘型自然硫矿床采用地下过热水溶融开采法(别称弗拉斯开采法),即将过热水通过钻孔注入含硫地层中,自然硫溶解后的含硫液体通过管道输送到地面,然后加工成结晶硫黄,或直接以液态硫作为产品。选矿方法主要为浮选法。青海省天峻县硫黄山自然硫矿选矿工艺流程如下:对于自然硫矿石提炼硫黄以后的尾渣(含硫15%左右),采用浮选法也可获得含硫61%的粗精矿。
