1。热钢钢筋网又称为热浸钢,他是在高温下把锌锭融化,在放入一些辅助材料,然后把金属结构件浸入钢槽中,热钢钢筋网使金属构件上附着一层锌层。热钢的优点在于他的防腐能力强,钢层的附着力和硬度(Hardness)较好
1. Hot steel reinforcing mesh is also called hot-dip steel. It melts zinc ingot at high temperature, puts some auxiliary materials into it, and then submerges the metal structure into the steel trough. Hot steel reinforcing mesh makes the metal component attach a layer of zinc. The advantage of hot steel lies in its strong anti-corrosion ability and good adhesion and hardness of steel layer
热钢钢筋网即把锌盐溶液通过电解,给镀件上镀层,一般来说不用加热,上锌量很少,遇到潮湿环境很容易脱落。钢筋网是纵向钢筋和横向钢筋分别以一定间距排列且成直角,全部交焊点均焊接在一起的钢筋网片。
Hot steel reinforcing mesh is to electrolyze the zinc salt solution to coat the plated parts. Generally speaking, it does not need to be heated, and the zinc content is very small, so it is easy to fall off in wet environment. The reinforcing mesh is a kind of reinforcing mesh which is arranged at a certain distance and at right angles with all the welding joints welded together.
2。钢筋网是纵向钢筋和横向钢筋分别以一定间距排列且成直角,全部交焊点均焊接在一起的钢筋网片。热钢针对热钢钢筋(英文:steel bar)网,热钢钢筋网厂家强烈建议用热钢
2. The reinforcing mesh is a kind of reinforcing mesh which is arranged at a certain distance and at right angles with all the welding joints welded together. Hot steel refers to steel bar mesh, which is strongly recommended by the manufacturer
热钢是化学处理,属于电化学反应。
Hot steel is a chemical treatment and belongs to electrochemical reaction.
冷钢是物理处理,只是在表面刷一层锌,所以锌层易脱落。建筑施工中多采用热钢。
Cold steel is a physical treatment, just brush a layer of zinc on the surface, so the zinc layer is easy to fall off. Hot steel is often used in construction.
连续热钢工艺:热钢钢筋网钢材 rarr;加热 rarr;冷却钢温度 rarr;钢 rarr;冷却
Continuous hot steel process: hot steel mesh steel rarr; heating rarr; cooling to steel temperature rarr; steel rarr; cooling
冷钢就是电钢,只有10-50g/m2,其本身的耐腐蚀性比热浸钢相差很多。采用电钢的相对便宜一些。
Cold steel is electrical steel, only 10-50g / m2, its corrosion resistance is much different from hot-dip steel. The price of electric steel is relatively low.
热钢钢筋网是钢体在热浸的条件下对表面钢,它的附着力(adhesion)很强,不容易脱落,热钢管虽然也出现锈蚀的现象,但在很长的周期可以满足技术、卫生要求。
Hot steel reinforcing mesh is the surface steel of the steel body under the condition of hot-dip. Its adhesion is very strong and it is not easy to fall off. Although the hot steel pipe is rusted, it can meet the technical and sanitary requirements in a long period.
3。工艺区别
3. Process difference
工艺的区别是:热钢钢筋网是将工件除油、酸洗、浸药、烘干后浸入溶化的锌(zinc)液里一定时间,提出来即可。
First of all, the difference of the process is that the hot steel reinforcing mesh can be extracted by immersing the workpiece in the solution of zinc (zinc) after oil removal, acid pickling, chemical soaking and drying for a certain period of time.
冷钢也叫电钢,是利用电解设备将工件经过除油、酸洗后放入成分为锌(zinc)盐的溶液中,并连接电解设备的负极;在工件的对面放置锌板连接在电解设备的正极,接通电源,利用电流从正极向负极的定向移动,就会在工件上沉积(sedimentation)一层锌。
Cold steel is also called electric steel. It uses electrolytic equipment to put the workpiece into zinc salt solution after oil removal and acid pickling, and connect the negative pole of the electrolytic equipment; place zinc plate on the opposite side of the workpiece to connect the positive pole of the electrolytic equipment, connect the power supply, use the current to move from the positive pole to the negative pole, and a layer of zinc will be deposited on the workpiece.

钢成品的区别:热钢钢筋网外表没有冷钢细腻(细致光滑或描写、表演等细致入微)光亮,但锌层厚度方面热钢是冷钢的几十倍。建筑钢筋网钢筋交叉点开焊数量不得超过整个网片交叉点总数的1%。并且任一根钢筋上开焊点数不得超过该根钢筋上交叉点总数的一半。钢筋网更外边钢筋上的交叉点不得开焊。热钢钢筋网防腐蚀(释义:指腐烂、消失、侵蚀等)性能也是电钢的几十倍。
Difference of steel products: the surface of hot steel mesh is not as bright as that of cold steel, but the thickness of zinc layer is dozens of times of that of cold steel. The number of open welding at the intersection of building reinforcement mesh shall not exceed 1% of the total number of intersections of the whole mesh. And the number of open welding points on any reinforcement shall not exceed half of the total number of intersections on that reinforcement. No welding shall be carried out at the intersection of the outermost reinforcement of the fabric. The anti-corrosion performance of hot steel mesh is dozens of times of that of electric steel.
