Sand pump special anti corrosion wear resistant repair coating:
A sand pump as the core component of sand-excavating ship,suffers the bad erosive wear from the sand gravel,though the sand pump manufacturers have used hard nickel,high chromium etc.abrasion resistant materials to prolong the service life,but it will still appear wear out phenomenon in the process of using, for the using unit,these wear out parts can only be scrapped.
Using Xiangyang City Hundred Shield Coating Material Co.,Ltd produced wear resistant coatings can effectively repair these wear out parts and put them into using again,the service life of repairing part can reach to the 3-6 times of the substrates (BD707 wear resistant coatings can reach to three times more than the substrates,BD7021 heavy medium abrasion resistant coating is the 6 times more than the substrates),the sand pump after repairing is in the process of using,if other parts of the substrates appear the abrasion again,we can still use wear resistant coatings to do the repairing (the parts after repairing will not wear out within 3 to 6 weeks),reciprocating like this,the service life of the sand pump will prolong for a few times,will get a considerable economic benefit.In order to prolong the usage time for maintenance one time,customers can except plug up the wear-out holes,can also smear a layer of (4mm-8mm thickness) abrasion resistant coatings to do the protecting on the whole inner wall of the sand pump during repairing.
