Diesel Engine Oil CJ-4 diesel engine oil is a high-end diesel engine oil second only to CK-4. Its various properties are more powerful than the current common CI-4 and CH-4. With the implementation of the National Sixth Standard, large-scale commercial vehicles have accelerated their upgrading, which has also prompted the gradual shift in fuel demand for diesel vehicles from low-level to high-level. Then, CJ-4, which is in a higher quality grade, will be the first choice for universal and cost-effective oil in the future. The newly launched CJ-4 Plus+ fully synthetic diesel engine oil from Sarlboro is blended with fully synthetic base oils and high-quality additives. The engine oil blended with fully synthetic base oil is suitable for a wider temperature range of the engine, has strong oxidation resistance and high temperature stability, and has a longer oil change interval. For the same oil film requirements, a fully synthetic engine oil can achieve a higher film strength at a lowe...

 In the production of chemical fibers, single-hole spinnerets are used to produce single filaments with smaller counts.  Its fineness is thicker than single filament in multifilament. The melted synthetic resin passes through the thin stream of the original liquid pressed from the pores of the spinneret and is formed by condensation. Or use a porous spinneret (for example, up to 50 holes) to spin, and then untwist drawing and separate filament winding into a monofilament package.  The thicker synthetic fiber monofilament of 200~300 tex (2~3 British branch) can be used as fishing net line and rope making. Thinner monofilaments can be used as artificial bristles. The finer monofilament is generally 1 to 1.3 tex (450 to 600 British counts), sometimes as fine as 0.6 tex (1000 British counts), and can be processed into stretch yarns for making elastic stockings, stockings and other textiles and other high-end knitwear. The textile made of monofilament is thin, transparent and ...

In the production of brushes, the materials often used in the brush industry can be divided into four categories according to their materials: plastic brush filaments, animal hair, metal brush filaments, and plant fiber brush filaments. Among them, the plastic wire also contains: 1. Nylon brush filament: Nylon brush filament is the most commonly used brush material, and it is a relatively good quality material among plastic brush filaments. Nylon filaments are relatively expensive. The main advantages of nylon brush filaments are: a. Good elasticity: For example, there are a lot of wires in the electric box. In order to protect the wires, we need to use a brush to seal it. If we use a good elastic brush wire, the brush wire can maintain long-term elasticity under the pressure of the wire. To maintain its sealing effect, the relatively weakly elastic brush filament will be pressed to one side by the wire and cannot spring back to the original place, resulting in a gap, resulting in a po...

When we go to purchase brush filaments, we usually choose according to our own customization requirements. The brush filaments that need to be designed and customized are not available in stock. You need to wait 3 to 7 days. Then you can customize the size of the brush filaments. How much do you know?   I often encounter people who say: 40 silk, 50 silk, 60 silk, what does "silk" mean here? Silk is an idiom, usually the thickness of the plastic is called how many filaments, 1 filament = 0.01 mm, then 40 filaments is a custom-made brush filament size of 0.4mm.   Size customization   "Silk" is just a common name, not a standard unit of length, and has not been used in technical books for a long time. However, it is convenient for many people to call it that way. However, according to the national standard, it should be expressed in millimeters. For example, a customer'sbrush filament is customized to nylon 612 with 60 filaments, that is, nylon 612 with a diameter...

Glossy abrasive filaments are mainly used to manufacture polishing and polishing brushes. Our company uses high-quality nylon raw materials to make various specifications (diamond, silicon carbide, alumina, ceramics) abrasive brush filaments by melt extrusion drawing. After the nylon yarn is blended into the abrasive sand, it integrates the characteristics of ordinary brushes and has a cleaning effect, which surpasses the industrial use of pure nylon yarn. The raw abrasive wire has good thermal stability, long-lasting temperature resistance, chemical inertness such as acid and alkali resistance, low water absorption, and maintains good rigidity and toughness under dry and wet conditions. Therefore, it is widely used in all walks of life.

1. Surface finishing of copper strip and aluminum strip coil; 2. Automobile wheel hub, gear processing, engine parts deburring; 3. Finishing treatment of compressor parts of refrigerators and air conditioners; 4. Remove surface burrs and chamfers after machining; 5. Polishing the surface of die castings; 6. Deburring the inner walls of deep holes and related holes; 7. Surface grinding before plating and painting; 8. Military weapons cleaning; 9. Decontamination and grinding of PCB circuit boards; 10. Textile sanding processing, denim decolorization, etc.; 11. Antique stone grinding, furniture and other industries grinding, etc.; 12. Angle grinder, pneumatic, mechanical tool grinding brush , etc.;

The green abrasive filament is a special brush filament blended with high-quality nylon as a carrier, uniformly dissolved in abrasive sand such as silicon carbide (SIC) and alumina (AO), so that the abrasive sand is firmly combined in the inner and surface of the brush filament . Grinding sand is melted into nylon and spun into filaments with high strength, good toughness and elasticity. It can grind, finish, polish and deburr irregular surfaces such as curved surfaces, concave and convex surfaces, and pipe inner walls without affecting the dimensional accuracy of the workpiece. Smooth finish, no dead corners, suitable for industrialized and efficient operation, and irreplaceable use of other hard abrasive blocks.
