硫酸钡如何使油漆颜色更白光泽度更亮? 　　硫酸钡在油漆行业的使用情况很普遍，在油漆生产工艺过程当然也是必不可缺少的填充原料之一，如何控制硫酸钡在油漆中的添加量呢，这就是个经验问题，如果添加的少的话，容易造成亮度比较低，添加太多的话，就会造成油漆在喷涂后过于鲜亮，所以起到的效果不适中，另外还跟硫酸钡的质量好坏也有一定要求，如果硫酸钡的白度好，钡含量高的话，就能提高油漆产品的质量，相反，如果硫酸钡的白度，钡含量低，对于油漆质量会产生很大的影响的，所以从事油漆生产企业一定要注意这个因素。 　　The use of barium sulfate in the paint industry is very common, in the production process of paint is of course will fill one of the raw materials can not be missing, how to control the barium sulfate in paints in addition, this is a question of experience, if you add a little, easy to cause the brightness is low, add too many words that will result in paint spraying too bright, so the effect is moderate, in addition to the quality of barium sulfate have certain requirements, if the whiteness of barium sulfate, barium content high, can improve the quality of products, paint the contrary, if the whiteness of barium sulfate, barium content the paint quality is low, will have a great impact, so in paint production enterprises must pay attention to this factor. 　　硫酸钡在不断开拓其品质优势能力体现的前提下，要以优势能力的开拓来增强其整体发展的实用效果，透过产品整体性带动，来迅速体现出产品实用基础能力的发展，充分提升产品实用基础的不断完善。产品质量提高了，产品成本降低了。选择硫酸钡就成了众多油漆厂家的首先填充料。 　　The premise of barium sulfate in the pioneering quality advantage of the ability to reflect, to develop the advantage of ability to enhance the overall development of practical effect, through the whole product driven, to quickly reflect the development of basic products and practical ability, and fully enhance products and constantly improve the practical basis. The quality of the product has been raised, and the cost of the product has been reduced. Barium sulfate has been chosen as the first filling material for many paint manufacturers. 　　当然，有些硫酸钡厂家为了获利，硫酸钡的质量并不纯，可能会添加其他白色粉末，所以在购买硫酸钡的时候，一定要仔细检查好硫酸钡厂家的产品质量及产品的纯度，确保质量没有任何问题的时候在放心购买，如果硫酸钡的质量存在问题的话，容易造成生产的油漆产品出现问题，所以一定要注意这方面的因素。 　　Of course, some manufacturers of barium sulfate in order to make a profit, the quality of barium sulfate is not pure, may add other white powder, so when the purchase of barium sulfate, the purity of product quality must be carefully check the barium sulfate manufacturers and products, ensure quality without any problems in the buy, if there is a problem of quality barium sulfate, easy to cause the paint production problems, so we must pay attention to these factors.

铅玻璃在熔断时有哪几种方法？　　熔炼铅玻璃离不开高温窑炉,铅玻璃熔窑有许多种,有烧煤气或天然气的,有烧油的,有电加热的.综述起来主要有三种熔断方式. 　　Smelting lead glass can not be separated from the high temperature furnace. There are many kinds of lead glass furnaces, such as burning gas or natural gas, burning oil and electric heating. There are mainly three ways of fusing 　　1、坩埚：一些铅玻璃和特殊光学玻璃是用坩埚窑来熔炼的,所说的坩埚就是耐火材料做的容器,外形有的象水壶,有的象短粗的杯子,将它们放置在高温窑炉中,烧得通红,再将原料加在里面. 　　1, lead glass and Crucible: some special optical glass is used to smelting crucible kiln, the container is made of refractory crucible, shape like kettle, some like a cup, placing them in the furnace, burned red, and then added to the raw materials inside. 　　2、玻璃液：在坩埚中原料发生各种高温化学变化,剧烈地沸腾着,放出很多气体,最后就"安静"下来了,变成了又浓又稠,软软的,就象刚刚熬好的麦芽糖一样的液体,这种液体叫做玻璃液. 　　2, glass melt in the crucible material: all kinds of high temperature chemical changes, violently boiling, emit a lot of gas, finally quiet down, turned into a thick, soft, just like cooked maltose as liquid, this liquid is called liquid glass. 　　3、实际生产：上面提到的坩埚炉容量小,供不上机械化生产的需要,所以在机械化生产中,玻璃都是在池炉中熔炼的.原料从用耐火砖砌的很大的池子的一端源源不断地加进去,熔炼好了的玻璃液从另一端源源不断地滴下来;滴到机器中去成型.池炉比坩埚可要大多了,有的池炉竞有一个小型的游泳池那样大,里面能容纳上千吨的玻璃液.玻璃液的温度很高,如果冷下来,就会凝固,所以要想将玻璃加工成一定的形状,就必须趁热制作。 　　3, the actual production capacity: crucible furnace mentioned above, not on the need for the mechanization of production, so in the mechanization production, glass melting furnace is in the pool. The raw material from one end of firebricks large pool of Everfount added, glass melting well from the other one end of Everfount trickle down; drop into the machine to molding. Furnace crucible can be bigger than, some competitive furnace has a small swimming pool as big, can accommodate thousands of tons of liquid inside the glass. The glass liquid temperature is very high, if the cold will solidify, so down to glass processing into a certain shape, it must take advantage of heat production.

朕这就走了。莫啸天本想让王不凡把对方留给马老三的那个电话号码给自己。这其中甚至还含有少的。那女上校朝莫啸天走过来。刘园园朝着虞子姗抱拳作揖。父手里的弹弓几乎是弹无虚发。
