电线接头挂锡的害处
作者：AntonioKN
去年就想动手把30多年老房子重新装修一下，各种杂七杂八的事情拖到今年，结果是好多都涨价了。
本来准备找装修公司，但是本地的没有靠谱的，找游击队直接pass。最后出于对自己能力的自信，自己搞吧。
利用周末和晚上的时间，陆陆续续搞了一个半月，一个房间的硬装差不多完成了三分之二，还差吊顶和刮腻子、刷大白。
截止到现在改造进度 ——
改造前如下图，老房子真的是一言难尽：墙歪、不垂直、墙体开裂、房顶开裂、地面开裂、墙面内部空腔、墙面渗水返潮、线路（基本都是2平的线）陈旧插座少等等。。。。
最新进度：重新布设电线和插座，更换门窗、墙面冲筋找平、地面房顶补漏、墙体空腔填充
截止到目前花费 ——
90系统窗两个，金额3600
工业吸尘器 150
电线零火地各100m 850
60米20线管+各种接头 110
靠尺三个 130元
搅拌棒+刮板等 40元
美巢石膏20袋 800元
美巢防水腻子 6袋 210
水泥沙160
86底盒 50个 150
铲墙皮的工具 35
电表箱+空开+漏保 170元
其它 100
目前花费大约6500左右。用到的手电钻、大锤等本来就有，所以没算进去。
推荐使用的工具和建议 ——
推荐工具：多功能切割机，拆除旧木窗，强烈推荐，安全系数远高于角磨机！！！
工业吸尘器：容量大，干湿两用，清洁好帮手
旧家电卖掉回血：空调卖了400，旧暖气片+铁水管卖了430
配电箱：老房子是没有配电箱的，所以配电箱和开关根据你的全屋线路设计来选择，建议卫生间和厨房一定要用带漏保的空开。
墙体开裂和地面缝隙修补：地面缝隙我首先使用堵漏王填充，然后用丙纶布防水覆盖。墙面开裂的地方拆除至红砖层，使用水泥沙修补，最后使用石膏找平
窗户四周缝隙处理：安装窗户一般都是使用发泡胶进行填充，从长远来说有漏水的可能。因为发泡胶内部会有空腔，而且不易发现，窗户沉降会有缝隙导致漏水。我的做法是底部全部用水泥砂浆填充，内外刷防水。左右和上方，扣掉一半发泡胶，用水泥砂浆填充，然后内外刷防水。
窗台石：对比线下的价格，我在网上购买 单个135元。手动后自己切割安装完活
暖气片：因为楼上楼下都装了地暖，冬天家里太热，所以还是选择使用暖气片。没事闲鱼里溜达，找到全新的铜铝复核暖气片，150自提拉回家，用白色自喷漆稍微喷了一下，完美。
电线接头：准备吊顶把线管藏起来，所以接头处进行挂锡。买的小锅送的500g焊锡条，融化后太少了，我又买了两根，才能浸入线头。
冲筋找平：为了后面做橱柜，墙面必须处理。大部分时间也用在这里了。使用的材料坑也很多，经过多方打听和查资料。最后选择使用美巢的石膏来进行。这里有个插曲，跑遍本地好几个装修市场都没有。最后只能高价在网上买。最后一次买，卖家直接帮我找到总代查本地有货的代理，驱车40km去拿 。冲筋找平的时候使用水平仪和墨斗线搭配，方便和很多
等吊完顶刮完大白，就剩铺地板和定制家具了。家具方面我准备部分定制部分买现成的。其实家具布局一定一奥在电路铺装的时候确定好，毕竟我不怎么喜欢用插排，投影和音箱不喜欢明线。
下一篇更新吊顶施工、地面自流平和人字拼地板安装和选购避坑事项。
自己动手装修的钱，我给nas添置了18TB硬盘和换了一个创世神机箱。机箱肯定要改色，正好可以在房间里高喷漆，后面更新细节，欢迎关注。

寿许廖4303新安装的铜线头和铜鼻子为什么应镀一层锡 -
郁香贱18993384387 ______ 严格讲,叫做“搪锡”. 除了防止氧化、易于接触外,还渗透到电线、铜鼻子的缝隙里(充满缝隙),使接线端子接触电阻、导体电阻进一步减小. 好的接线端子在生产出来时就“搪”了1层锡,用时更方便,否则,放久了才用不容易粘锡.
寿许廖4303一条通220V电的电线,接头用烙铁焊锡焊接,通电后焊锡会化掉吗? -
郁香贱18993384387 ______ 接头发热的原因是导线接头的接触电阻过大,通电时发热,发热量=I²*R(接触电阻).良好的焊接且电流小于导线安全截流量是不会熔化的.因为焊接接头的接触电阻很小,不会在焊接处产生额外的发热.
寿许廖4303电线接头挂锡后需要再并联一根电线怎么办? -
郁香贱18993384387 ______ 不能这样并接的,既然原来的线都搪过锡了,那么你把这根新电线拉直,也用电烙铁搪一下锡,然后与原来的再一起用电烙铁搪锡,就可以并在一起(焊在一起),而且体积也不会那么大.
寿许廖4303电线接头用焊锡胶布好还是用接线端子好 -
郁香贱18993384387 ______ 用接线端子好
寿许廖4303裸铜线镀锡线胶线的生产对身体有害处吗 -
郁香贱18993384387 ______ 有,因为锡中有一定量的金属元素对人体有害,不过镀锡可以防锈,当看见有一些混浊的金属层时一定不要除去,因为那是一个天然保护层可以隔离氧气防止生锈
寿许廖4303电线搭接挂锡符合规定吗 -
郁香贱18993384387 ______ 当然可行了,锡焊的作用就是固定和导电,先把电线绞接在一起,再上锡焊,再包扎.
寿许廖4303这样电线接头会烧焦吗?(有加分) -
郁香贱18993384387 ______ 你的这次事故不会太直接影响到埋在墙里头的接头,如果确是接的牢靠的话今后用电只要不超载也不会有太大影响,但接头毕竟是线路上的相对薄弱环节,年久了表面氧化接触电阻增大会发热引发故障,所以尽量不要将接头直埋,可以在接头处做个暗盒.这种情况使墙面带电引发安全危险不大.
寿许廖4303公建的开关插座的电线接头需要涮锡处理么 -
郁香贱18993384387 ______ 开关插座的接头没有必要,但电源线之间的铰接再用焊锡处理最好.
寿许廖4303你家装修电线接头焊锡了吗 -
郁香贱18993384387 ______ 只要掌握接线技巧根本用不着焊锡的,接线方法很多,有手工专业技能的接线,有压线板接线,有接线柱接线,有油压式接线,这一切都做得很好就不需要焊锡了,如果以上不放心在条件的允许情况之下加上焊锡当然更完美了,最起码100%不产生接触电阻了.
寿许廖4303低压电器的电线接头哪些地方需要粘锡
郁香贱18993384387 ______ 一般情况:所有导线终端(压接线鼻子和不压接线鼻子)需要连接用电设备的地方要搪锡.电缆和电线接头,线径较小的可以对扭后搪锡,较粗的电缆需要机械压接或爆炸压接.
