气门嘴

本周收到一个客户气门嘴询价,跟客户确认之前采购过此产品,由于客户对此产品比较了解,给客户介绍的时候比较详细,客户也觉得我们是专业的工厂。目前正在跟合作伙伴商量,期待客户的好消息!

铜材是气门嘴的主要原料,其铜、锌、铅和铁的含量有严格的   标准和性能要求。

气门嘴价格影响

铜材的分析、橡胶的硫变曲线、气密性试验,气门嘴的高温密气试验、气门嘴低温密气试验、铜材的抗拉强度、气门嘴打弯断裂试验、橡胶老化试验等气门嘴都是质量检测的重点。

一是铜越来越少,锌越来越多,降低了抗拉强度,不符合   标准;

二是铅和铁普遍超标,甚至超过标准的10倍,极易引起气门嘴断裂;

三是材质的超标和不稳定引起嘴体与橡胶的粘合困难,容易脱胶,造成不可预测的后果
