铜丝发黑的原因是多种因素造成的,不仅仅是配方问题åQŒè¿˜ä¸Žé“œä¸æœ¬íw«æ‰€å¤„的状态、橡胶加工工艺、橡胶硫化工艺、电¾~†çš„¾l“构、护套橡胉™…æ–V€ç”Ÿäº§çŽ¯å¢ƒç­‰è¯¸å¤šå› ç´ æœ‰å…³ã€?/span>

2、是铜丝退火原因造成的ã€?/span>

â‘?˜qžæ‹‰˜qžé€€çš„冷却水一般都是用自来水、地下水åQŒç”±äºŽæ°´è´¨å„åœîC¸ž®½ç›¸åŒï¼Œæœ‰äº›åœ°åŒºæ°´è´¨çš„PH å€ÆD¾ƒä½Žï¼Œåªæœ‰5.5~5.0(正常æ˜?.0~7.5)åQŒæŠŠåŽŸæ¥ä¹›_Œ–液中抗氧化æÑa膜都清洗掉了åQŒé€€ç«åŽçš„é“œ¾U¿æ˜“氧化、发é»?

â‘?在普通拉丝机拉好的成品铜丝在另一条退火线上退火,冷却水也没有使用抗氧化剂åQŒæŠ—氧时间短åQŒå¾ˆå¿«å°±ä¼šå‡ºçŽ°æ°§åŒ–发黑现è±?


3、是一些老厂˜q˜æ²¿ç”¨é€€ç«çŽ×来退火,以下几种原因也会造成氧化、发黑:

â‘?该退火çŽ×螺母没拧紧,冲完二氧化碳或高¾U¯æÛ后漏æ°?
