网址:http://www.scvc8.com  时间:2019-05-20 13:48:28

  随着荧光增白剂ob价格频频攀新高,很多使用荧光增白剂ob做塑料增白的老板,无法承受荧光增白剂ob的高价格,成本上无法承受,有的老板不在往塑料中添加荧光增白剂,有的老板转而使用荧光增白剂127,因为荧光增白剂127的价格只有荧光增白剂ob的一半,添加量上基本相同,荧光增白剂ob能够解决的问题荧光增白剂127也能基本达到,如果真实如此,难道荧光增白剂ob就要退出了塑料添加剂的舞台了吗?当然不是,因为荧光增白剂127有自身的优点,荧光增白剂127可以代替荧光增白剂ob,但是荧光增白剂127的劣势同样也是致命的,这导致荧光增白剂127不可能完全替代荧光增白剂ob。那么到低荧光增白剂127优缺点有哪些呢?为什么既能代替又不能完全代替荧光增白剂ob呢?这就需要了解荧光增白剂127的优缺点,下面简单给各位分析一下。
  With the price of fluorescent brightener ob rising rapidly, many bosses who use fluorescent brightener ob as plastics whitening agent can not afford the high price of fluorescent brightener ob, and the cost is unbearable. Some bosses do not add fluorescent brightener to plastics, and some bosses use fluorescent brightener 127 instead, because the price of fluorescent brightener 127 is only half of that of fluorescent brightener ob. Basically the same, the problem that fluorescent whitening agent ob can solve is that fluorescent whitening agent 127 can basically achieve. If this is true, will Fluorescent Whitening Agent OB withdraw from the stage of plastic additives? Of course not, because fluorescent whitening agent 127 has its own advantages, fluorescent whitening agent 127 can replace fluorescent whitening agent ob, but the disadvantages of fluorescent whitening agent 127 are also fatal, which makes it impossible for fluorescent whitening agent 127 to completely replace fluorescent whitening agent ob. So what are the advantages and disadvantages of low fluorescent whitening agent 127? Why can we not replace the fluorescent whitening agent ob completely? This requires understanding the advantages and disadvantages of fluorescent whitening agent 127. Here is a brief analysis for you.

  和荧光增白剂ob-1对比
  Contrast with fluorescent whitening agent OB-1荧光增白剂127又叫荧光增白剂(378),主要用于PVC增白剂,和人造皮革的增白,尤其对各种塑料及塑料制品均具有很好的增白效果。荧光增白剂127价格便宜,价格基本上和荧光增白剂ob-1相同,而且荧光增白剂127和荧光增白剂ob-1比较来说,荧光增白剂127没有迁移问题,混匀上比荧光增白剂ob-1也要容易,只是荧光增白剂127的耐温性能没有荧光增白剂ob-1那么强,但荧光增白剂127也能耐温220度,且完全满足pvc生产环境,那么我可不可以用荧光增白剂ob-1来对pvc增白呢?当然可以,但是首先你得做实验,确定自己的混匀设备能够将ob-1充分的混匀,使用荧光增白剂ob-1作为塑料增白助剂,混匀时间是荧光增白剂127的3倍左右,而且你还得往里面添加分散剂这种有利于荧光增白剂ob-1分散混匀的助剂,这也是一块成本。
  Fluorescent whitening agent 127, also known as fluorescent whitening agent (378), is mainly used in PVC whitening agent and artificial leather whitening, especially for various plastics and plastic products with good whitening effect. The price of fluorescent brightener 127 is cheaper than that of fluorescent brightener ob-1. Compared with fluorescent brightener OB-1 and fluorescent brightener 127, fluorescent brightener 127 has no migration problem and is easier to mix than fluorescent brightener ob-1. However, the temperature resistance of fluorescent brightener 127 is not as strong as that of fluorescent brightener ob-1, but fluorescent brightener 127 can also withstand 220 degrees of temperature and finish. Fully meet the production environment of pvc, then can I use fluorescent whitening agent OB-1 to whiten pvc? Sure, but first you have to do experiments to make sure that your mixing equipment can fully mix ob-1, using fluorescent whitening agent OB-1 as plastic whitening aids, mixing time is about three times as long as fluorescent whitening agent 127, and you have to add dispersant into it, which is beneficial to the dispersing and mixing of fluorescent whitening agent ob-1, which is also a cost.

  Contrast with fluorescent whitening agent ob和荧光增白剂ob对比看,荧光增白剂127的劣势是不稳定,在室外环境下荧光增白效果降低很快,20天后增白效果只有最初的40%,但是荧光增白剂127的价格只有荧光增白剂ob的50%,那么用荧光增白剂127代替荧光增白剂ob不就不可以了吗?这个还得从中国的从商环境说起了。

  Compared with fluorescent whitening agent ob, the disadvantages of fluorescent whitening agent 127 are unstable. The effect of fluorescent whitening in outdoor environment decreases rapidly. After 20 days, the effect of fluorescent whitening agent 127 is only 40% of the original effect, but the price of fluorescent whitening agent 127 is only 50% of that of fluorescent whitening agent ob. This also comes from China's business environment.
  大家知道pvc塑料行业很多和建筑行业相关,上下水尤其是污水管道很多实用pvc管道,这些管道基本上都是埋在地下,根本就看不见,所以实际上白或者不白都没有关系,但是作为采购人员,在市场上采购的时候却是看得真真切切,两家产品一对比,水黑水白一目了然,在浑然不知的情况下用屁股做出决定,购买自己喜欢的颜色,也自然选择那个更白的,应为更白的对应着更加的纯净,用料也是最好,所以厂家拼尽全力让自己的产品更白,起码是采购员看到的那一刻产品最白,至于埋到地下后是不是很白,那就没有关系了。荧光增白剂127对塑料的增白效果很强,而且能够持续15天的时间白度很好,这已经满足了市场的需求,所以从这一点考虑荧光增白剂127可以用在pvc低端产品的增白的,但是对于哪些高端的且使用者天天能够看到的产品,那么就必须使用荧光增白剂ob,因为荧光增白剂ob的增白效果持久,不容易在室外氧气和紫外下情况下褪色。

  As you know, many PVC plastic industries are related to the construction industry, and many practical PVC pipes, especially sewage pipes, are basically buried in the ground and can not be seen at all, so in fact, white or not white has nothing to do with it, but as a purchaser, when purchasing in the market, they can see the truth, the two products are one-to-one, water black and water white at a glance. However, in the case of ignorance, make a decision with the buttocks, buy the color you like, and naturally choose the whiter one. The whiter one corresponds to the cleaner one and the best material. So the manufacturer makes every effort to make his products whiter, at least the whitest one the purchaser sees at that moment. As for whether the products are very white after burying underground, it does not matter. Fluorescent whitening agent 127 has a strong whitening effect on plastics and can last for 15 days. This has met the market demand. Therefore, from this point of view, fluorescent whitening agent 127 can be used to whiten low-end products of pvc. But for those high-end products which users can see every day, it is necessary to use fluorescent whitening agent ob, because fluorescent whitening agent ob. The whitening effect of ob is durable, and it is not easy to fade under outdoor oxygen and ultraviolet radiation.
