Dongfeng Cummins helps Tianlong KL/Tianjin KR ushered in the era of network marketing
On January 6, 2019, the new generation Dongfeng Tianlong KL and Dongfeng Tianjin Jin KR were listed. These two freight cars are new platform upgrade products that Dongfeng Commercial Vehicle has built over the past five years based on 50 years of experience in car manufacturing and craftsmanship. When the two models match the Dongfeng Cummins engine, the performance is more stable and more reliable.
300mm Meltblown Spinneret for Meltblown Medical Mask Nonwoven Fabric Producing
Melt-blown spinning is to blow a molten polymer through a high-temperature high-speed gas to refine the polymer into a filament to form a nonwoven fabric.
1. Stainless steel wear resistant and corrosion resistant.
1) :Meltblown Die Head Can be Customized within 100-3200mm
Features
Optimized design, hole number encryption, high output, reduced production costs
The number of holes per spinneret is 13% less than jier. Less of holes, then less of yield.
L/D ratio (small hole length): Common 1:10, Our Company 1:15, our length is 50% longer than common spinneret, the top of the spinneret is strengthened, not easy to deform, ordinary hardness HRC (25-28° ),jier hardness HRC (34-38 °) has a longer service life.
Common spinneret use 'Electric spark punching and manual drilling'. Shortcoming: The hole is not straight, multi-slanted hole, hole wall is not smooth, the verticality and straightness are not good. Our company uses CNC high-speed machining center processing, the holes of our product without slanting holes, verticality and straightness is very good, There will be no serious phenomenon of "spot" floating wire caused by merged wire and broken wire.
Due to the structural factors of the conventional spinneret, there is often uneven discharge. Our company adds static mixing deflector to the melt chamber channel for the defects of the spinneret., so that the melt is evenly mixed in all parts of the chamber while the air duct structure data is improved. Make the quality of the products more perfect.
Product Advantages
Melt blown die head
1. Encrypted holes, more output
