我厂生产的天然气灶的燃烧器及支脚采用成本较低、设备简单的热浸法渗铝,有效地提高了抗高温氧化及抗天然气腐蚀(SO_2、H_2S 等)能力,与未渗铝的零件相比,900℃下使用寿命有显著提高。1.热浸法渗(?)工艺热浸法渗铝即液体渗铝,工艺流程为:除油→冷水冲洗→除锈→冷水冲洗→表面预处理→烘干→热浸铝→甩光→钝化。用汽油或化学法除油,后者的配方为洗净剂。“664”1%、“105”1%、“6503”1.5～2%,其余为水,使用时加热煮沸;除油后
The burners and legs of the gas stoves produced by our factory are of low cost and simple hot dip aluminizing, which effectively improves the capability of resisting high temperature oxidation and anti-natural gas corrosion (SO_2, H_2S, etc.) Compared to 900 ℃ life has significantly improved. 1. Hot-dip infiltration (?) Hot-dip aluminizing process that is liquid aluminizing, the process is: degreasing → cold water rinse → rust → cold water rinse → surface pretreatment → drying → hot dip aluminum → polishing → Passivation. With gasoline or chemical degreasing, the latter formula for the detergent. “664 ” 1%, “105 ” 1%, “6503 ” 1.5 ~ 2%, the rest is water, heated and boiled;
