如何提高塑料造粒的利润水平

 

一是做表面有字的料。常见的PE或PP粒，表面有字的基本上都比没字的便宜一千多，只要我们能把表面的字往掉，再造粒。这不但可以进步利润，而且在收货上也有了很强的竞争力，不怕别人抬价了。

 

二是回收一些有油污的料。这种料需要清洗后才能造粒，一般人都嫌麻烦，所以这种料也比较便宜。

 

三是回收一些有油漆的料。如汽车塑料，也就是说喷了一层油漆的aBS。

 

四是回收镀铝膜。这种料价钱极低，但往掉镀铝层后就是很好的料，可大幅地进步造粒的利润水平。

 

另外还有很多冷门的料，只要我们多关注一下平时没什么人收的料，再找出相应的处理方法，都会给造粒带来很不错的利润的。

 

Sintered Ferrite Magnet, hard ferrite, hard ferrite magnet is also called Ceramic Magnets.
Sintered ferrite magnets are available in isotropic magnet and anisotropic magnets. The magnetic properties of isotropic ferrite are low. Since they have nearly the same magnetic properties in all directions, so isotropic ferrite magnets can be magnetized in many different directions or in multi-poles. Anisotropic ferrite magnets have better magnetic properties compare with isotropic ferrite magnets. However this type of magnets can only be magnetized along a preferred direction.

Permanent ferrite magnets are made of hard ferrites, which have a high coercivity and high remanence after magnetization. Iron oxide and barium or strontium carbonate are used in manufacturing of hard ferrite magnets. The high coercivity means the materials are very resistant to becoming demagnetized, an essential characteristic for a permanent magnet. They also have high magnetic permeability. These so-called ceramic magnets are cheap, and are widely used in household products such as refrigerator magnets. The maximum magnetic field B is about 0.35 tesla and the magnetic field strength H is about 30 to 160 kiloampere turns per meter (400 to 2000 oersteds). The density of ferrite magnets is about 5 g/cm3.

The most common hard ferrites are:
Strontium ferrite, SrFe12O19 (SrO·6Fe2O3), used in small electric motors, micro-wave devices, recording media, magneto-optic media, telecommunication and electronic industry.
Barium ferrite, BaFe12O19 (BaO·6Fe2O3), a common material for permanent magnet applications. Barium ferrites are robust ceramics that are generally stable to moisture and corrosion-resistant. They are used in e.g. loudspeaker magnets and as a medium for magnetic recording, e.g. on magnetic stripe cards.

Why choose Ferrite Magnet?
1. Low cost and low price.
The raw material cost is very cheap and manufacturing process is simple. So the price if it is very low.
2. Nice temperature stability
Ferrite magnets can be used in the working temperature from -40℃ to 200℃.
3. Well prevent  corrosion
The raw material of sintered ferrite magnet is oxide, so ferrite magnets will not be rusted under severe environment nor affected by many chemicals.
