High Quality Epoxy Polyester Powder Coating Paint

Powder Coating

1.General introduction:

Powder coatings are mixed with a certain proportion of the resin, fillers, curing agents and other additives, then prepared by hot extrusion ,crushed  and sieved.The products are stable at room temperature storage, then baking heat melted and solidified to form a smooth and bright permanent coating to achieve the purpose of decoration and corrosion.

2.Features:

1).The products are non-toxic, solvent-free and non-toxic volatile substances, there are no intoxication, no fire, no "three wastes" emissions and other pollution problems, in full compliance with national environmental laws. 
2).Raw material utilization is high, the highest utilization rate even more than 99%. 
3).After being pre-coated handle, disposable construction, without primer, you can get a sufficient thickness of the coating, easy to automate operation, high production efficiency, reduce costs. 
4).Dense coating adhesion, good impact strength and toughness, high coverage corners, with excellent resistance to chemical corrosion and electrical insulation properties. 
5).Powder coatings storage and transport are safety and convenience.
   
3.Powder physical properties: 
 
   Proportion : 1.2-1.8 (depending on the color and gloss ) .
 
   Particle size distribution: 100% less than 125 microns (more than 85%          
   between 60 to 90).

   Liquidity(180°C):22~35mm.

   Curing conditions:200°C,10 minutes.

4.Average coverage:

8-10m³/kg, the membrane is 60μm
(calculate by 100% utilization rate of powder coating).

5.Packing:

   Carton packaging, lined with double polyethylene bag, net weight 20 kg.
   
6.Storage requirements:

   Store below 30 °C, ventilated, dry, clean room, not near the fire, heat, direct sunlight, open dumps is prohibited.Under this condition, the powder can be stable for 12 months, more than the storage period may be re-examined, such as the results meet the requirements, can still be used.

7.Health and safety:
 
This product is non-toxic. 
In the course of inhalation of dust should be avoided. The operators should wear  appropriate dust mask and glasses.

5). We will do our best to service you all the time if you have the further question.


 

Sphercial Roller Bearing

Spherical Roller Bearings are most suitable option for applications that need shock resistant components yet this is not the only quality these Bearings have. These Bearings can handle heavy loads because of their rings` alignment. Due to the curved outer ring, Spherical Bearings come with self aligning capabilities that make it possible to absorb shocks and also enable the apparatus to carry high axial and radial load even in harsh environment with lot of vibration. Even with this rugged working environment, Roller Bearings tend to have high precision.

DESIGN
Spherical Bearings have two rows of rollers that are separated by a cage or rib that could be sealed or unsealed depending on the specific model and application, external raceway and dual raceways in inner ring to support rotating shaft. Amazingly the quality and alignment of raceways, cages and rings define the overall performance and quality of the product. Asymmetrical rollers increase performance and precision while symmetrical rollers offer better load distribution, lesser vibration that ultimately leads to durability.

MATERIAL
These Bearings are manufactured with several kind of material based on the application and working environment. Chrome steel is one of the most popular materials used in production of these Bearings because of its durability yet sheet steel, polyamide and brass are also used for some applications. One of the most important parts of Spherical Bearings is the cage that holds bearings at their place. That cage is usually manufactured with pressed steel or brass because both of these materials offer strength as well as temperature resistance.

These Bearings tend to have seals in order to prevent contaminants like dirt, liquid, debris as well as harsh temperature. This type of these bearing doesn`t even need lubrication if they do not exceed 50% of their maximum allowed RPM.

APPLICATIONS
Spherical Bearings are essential part of heavy machines like gearboxes, turbines, mechanical fans, constructions equipment, mining equipment and drilling equipment. Roller Bearings are available in multiple standard sizes and dimension yet they are also made with custom sizes and specifications.

MODELS AND VARIATIONS
Usually these Bearings come in two different types that have totally different design, structure, specifications and applications.

Single Row Spherical Roller Bearings
These are also known as Barrel Bearings because of their design and they are widely used where only low radial load carrying capacity is required. Other than the load capacity difference, Single Row these Bearings is quite similar to their counterpart in terms of performance and durability.

Double Row Spherical Roller Bearings
These are used where high radial load carrying capacity if required and that make them an essential part of almost all heavy duty machinery out there. The design difference between these two is obvious; Double Row Roller Bearings come with central flanges that optimize the overall performance of the apparatus.
