Dye can bring a little color to life, most clothing is color with dyes, modern manufacture dyes can be costly, natural dyes from plan t and animal products have been used since ancient times, so this week, we describe by natural way to dye world, the advice comes from information written by Jenny Tim of the intermedial technology development group in Briton, this anti group is now called practical action, there are several messages to put dye onto material, the vent message for example, can be used to dye wool with onion skins, for this example, use 100 grams of natural wool, the wool must be clean, leave it overnight in water and liquid soap, then wash it with clean water that is a little warm, gently out the water, a solution called a moderant is used in the dying process, a moderant helps fix the dye to the material, traditionally moderants were found in nature, wood ash is one of example, but chemical moderants such as ironare popular today, iron is so would in many stores, it is often mixed with queen of daughter, a finding powder commonly used in cooking.

使用染料可以为生活带来更多的色彩。许多的布料都是通过染料来上色的。现代工业制造的染料通常都非常的贵，从古时起，人们就知道从植物或者动物产品中提取天然染料。这周，我们就来讨论一下如何用天然的方法来给羊毛着色。这一建议来自英国中级技术发展组的Jenny Dean的信息。这一古老贫穷的小组现在被称为实用性活动。把染料加到材料上有几种方法。其中之一是大桶法。举例来说，就是用洋葱皮来染羊毛。这一例子中，用100g的天然羊毛。羊毛必须清洗。用液体肥皂浸泡过夜。然后用温的干净的水冲洗它。轻柔地把多余的水分压挤出来。一种叫做媒染的溶剂也用于染洗过程。媒染是用来固定染料和材料的。传统的方法是，媒染是来天然的，比如木灰。但是像明矾这样的化学媒染在今天也是很流行的。明矾在许多商场都有出售。它通常和一种经常被用于烹调的粉状物-酒石混在一起。我们用多一点点的辛苦，来交换多一点点的幸福

MPH plastic magnetic pump complies with JB/T7742-1995Standard for Small Magnetic Transmission Centrifugal Pump. Its flow-through parts adopt PPS with corrosion resistance to most acid, alkali and salt (except oxidable acid like strong sul-furic acid, nitric acid and aqua regia). Its performance is close to the chemical performance of F4, which can resist to most organic solvents under 100℃, especially to the mixture of gas and carbinol. Thus it is an ideal pump for acid and alkali industries.

MPH型塑料磁力泵符合JB/T 7742-1995《小型磁力传动离心泵》标准，过流部件采用聚苯硫醚，不受大多数酸、碱、盐的侵蚀(除氧化性酸如浓硫酸、硝酸和王水等)，其性能接近于聚四氟乙烯的化学性能，在100℃以下能耐大多数有机溶剂，特别能耐汽油和甲醇的混和液，是酸碱工业中的理想用泵。
