In order to extend its applications in various fields, capsulated amorphous phosphorus was used as flame retardant of ultra-high molecular weight polyethylene, and four kinds of carbon blacks were selected as antistatic agents.

针对超高分子量聚乙烯阻燃、抗静电性能差，不能满足某些场合应用需求的现状，利用微胶囊化红磷和发黑作为改性剂，对UHMWPE进行改性，其氧指数达到24.2％～29.5％，表面电阻率降到1×10~9Ω以下，实现了阻燃、抗静电的目的，并且基本保持了UHMWPE原有的优异耐冲击与耐磨性能，提高了它的热变形温度与弯曲强度，从而拓宽了UHMWPE的应用范围。

六、化工原料：主要包括各种电镀原料及金属表面处理剂，如中捷的醋酸镍、醋酸铜、氟化镍、硫酸钴、醋酸钴、氢氟酸、云南的锡酸钠、台湾的焦磷酸亚锡、奥龙的阴离子交换树脂、阳离子交换树脂、阻垢剂、清灰剂、除垢剂、创辉的磷化剂、洗板水、除腊水、除油除锈水、美国的钢铁常温发黑剂、代白代黑、枪色黑合金等。

Asked a little Green Lizard, as he ran past him with his tail in the air.

现在我总算看见他了，他的头发黑得像风信子花，他的嘴唇就像他想要的玫瑰那样红﹔但是感情的折磨使他脸色苍白如象牙，忧伤的印迹也爬上了他的眉梢。

In addition, there are two strands of the head is also black, and are rust, rust can be seen because of lead wire resistance increases, resulting in the signal can not be smooth, telephone through the audio signal, the low band signal can also only phone, there is always the voice of flap, and the use of the ADSL band signal is relatively high, head through the rust on it is very difficult, leading to slow or stop signal transmission.

此外有两处绞合的线头处也发黑了，都是锈，可见正是因为导线生锈导致电阻增大，导致信号不能畅通，电话通过的音频信号，频带低，信号还能通过，只是电话里老是有啪啪的声音，而ADSL的信号使用的频带比较高，线头生锈了就很难通过，导致信号传输变慢或者断流。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
