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 feels good.  N
