焊条心:15号钢,Φ4公厘。涂料成分(重量):二氧化锰33分,四氧化三铁2分,石棉粉8分,滑石粉25分,粉墨灰10分。涂制方法:以上药品都要经过40～50号筛孔过筛,按照配方混合均匀;并按体积比1:1加入水玻璃(浓度是35～40°波美),随加随搅拌,调成糊状,稀稠要适度。然后把已经清理过的焊条心插在调好的涂料中;焊条心抽出速度的快慢,可以调节涂焊的厚度。涂层的厚度
Welding rod heart: 15 steel, Φ4 mm. Paint ingredients (weight): 33 points of manganese dioxide, iron oxide 2 points, asbestos powder 8 points, talc 25 points, ink ash 10 points. Coating methods: The above drugs have to go through 40 to 50 mesh sieve, according to the formula mixed evenly; and by volume ratio of 1: 1 water glass (concentration is 35 ~ 40 ° Baume), with the increase with stirring, tune Into a paste, dilute thick to moderate. Then the electrode has been cleaned in the heart inserted in the tune of the paint; the heart of the speed of extraction speed, you can adjust the thickness of welding. The thickness of the coating
