经长期摸索,找出了一种成本低、来源广、操作简便的防渗碳涂料。其配方为:膨润土和滑石粉各一半,用水调成稠糊状。使用时均匀涂于不需渗碳的都位,然后再粘一层铁锈粉(即机加工的铁屑年久锈蚀后碾碎,过100目筛),稍干即可入炉(我们用箱式电炉固体渗碳)。经实践证明,该涂料有如下优点:材料来源广、成本低;工艺简单、操作方便;涂料不易裂、不脱 After long-term exploration, found a low cost, wide source, easy to operate anti-carburizing coating. The formula is: bentonite and talc half of each, transferred into a thick paste with water. When used evenly coated without carburizing all the bits, and then stick a layer of rust powder (ie machining of scrap pieces of rust crushed after a long time, over 100 mesh sieve), a little dry into the furnace (we use the box Electric furnace solid carburizing). The practice proved that the coating has the following advantages: wide source of raw materials, low cost; process is simple, easy to operate; paint is not easy to crack, do not detach
