河南优质分子筛 原料气净化用分子筛 空气净化分子筛

分子筛有天然沸石和合成沸石两种。它是一种人工合成且对水分子有较强吸附性的干燥剂产品。分子筛的孔径大小可以通过加工工艺的不同来控制，除了吸附水汽，它还可以吸附其他气体。分子筛具有均匀的微孔结构，它的孔穴直径大小均匀，这些孔穴能把比其直径小的分子吸附到孔腔的内部，并对极性分子和不饱和分子具有优先吸附能力，因而能把极性程度不同，饱和程度的不同，分子大小不同及沸点不同的分子分离开来，即具有“筛分”分子的作用，故称分子筛。

1、具有极高，深度干燥分离度；

2、可以有效地避免分离时所产生共吸附现象，提高产品得率；

3、可以在同一系统中同时完成干燥和物质的纯化；

4、在较高的温度条件下，同样具有一定的吸附容量；

5、分子筛系统较其他干燥和分离装置，设备投资低，运转成本低。

3A分子筛的孔径是3A，主要用于吸附水，不吸附直径大于3的任何分子，根据工业上的应用特点，分子筛具有快吸附速度、再生次数、抗碎强度及抗污染能力，提高了分子筛的利用效率并延长了分子筛的使用寿命，是石油、化工行业中气液相深度干燥、精炼、聚合所必需的干燥剂。

4A分子筛的孔径为4A，吸附水， 、乙醇、 、、 、乙烯、 ，不吸附直径大于4A的任何分子(包括 )，对水的选择吸附性能高于任何其他分子，是工业上用量 的分子筛品种之一。

5A分子筛的孔径为5A，能吸附小于该孔径的任何分子，主要应用于正异构烃分离、变压吸附分离及水和 的共吸附，基于5A分子筛的工业应用特点，我们生产的5A分子筛选择吸附高、吸附速度快、特别适用于变压吸附，可适应各种大小的制氧、制氢、制 等气体变压吸附装置，是变压吸附行业中的选择。

13X型： 酸盐的晶体结构不同（ 比大小不同样），形成孔径为9D10A的分子筛晶体，称为13X（又称钠X型）分子筛；用Ca2+交换13X分子筛中的Na+，形成孔径为9A的分子筛晶体，称为10X（又称钙X型）分子筛。

Molecular sieve is introduced
Molecular sieve has two kinds of natural zeolite and synthetic zeolites.It is a synthetic and strong adsorption of water molecules of desiccant products.Molecular sieve aperture size can be controlled by different processing, in addition to the adsorption of water vapor, it can also be other gas adsorption.The microporous structure of the molecular sieve is uniform, and its cavity diameter size uniform, can the cavity is smaller than the diameter of the molecular adsorption to the interior of the pore space, and the polar molecules and unsaturated molecules have preferential adsorption ability, thus can bring a different polarity degree, the degree of saturation is different, different molecular size and the boiling point of different molecular separation, which have the function of the "screening" molecules, therefore calls the molecular sieve.
Molecular sieve characteristics
1, has a very high, deep dry separating degree;
Produced during the 2, can effectively avoid the separation of adsorption phenomenon, improve the product yield;
3, can be done in the same system at the same time drying and purification of materials;
4, under the condition of high temperature, also has certain adsorption capacity;
5, molecular sieve system than other dry and separation devices, low equipment investment, operation cost is low.

3 a molecular sieve pore size is 3 a, mainly used for the adsorption of water, not any molecular adsorption diameter greater than 3 a, according to the industrial characteristics of application of molecular sieve has a fast adsorption speed, number of regeneration, crushing strength and ability to resist pollution, improve the utilization efficiency of the molecular sieve and prolong the service life of molecular sieve, dry gas liquid phase depth is petroleum, chemical industry, refining, necessary of desiccant polymerization.
Aperture for 4 a, 4 a zeolite adsorption of water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, not any molecular adsorption diameter greater than 4 a (propane), the selection of water adsorption performance than any other molecules, one of the largest varieties of molecular sieve is industrial use.
5 a molecular sieve pore size for 5 a, can adsorption is less than the diameter of any molecule, is mainly used in heterogeneous hydrocarbon separation, pressure swing adsorption, adsorption separation and water and carbon dioxide, based on the industrial application characteristics of 5 a molecular sieve, we in the production of 5 a molecular sieve choose high adsorption, adsorption speed, especially suitable for the pressure swing adsorption, can adapt to all kinds of size of oxygen, hydrogen, carbon dioxide and other gases pressure swing adsorption device, is the best choice in industry pressure swing adsorption ().
13 X: silicon aluminium acid salt crystal structure is different (silica alumina ratio, size is not the same), the formation of aperture for 9-10 a molecular sieve crystal, known as molecular sieve 13 X (X) is also called sodium;Exchange with Ca2 + Na + in the 13 X molecular sieve, formation aperture for 9 a zeolite crystals, called 10 X (also known as calcium X) molecular sieve.
