Problems solved by technology

However, since the water jet plate of the spunlace machine is installed in the slit between the clamping device and the water diversion plate, the water inlet of the water spray hole is easily worn when it is pulled out for cleaning, and the worn water nozzle will cause the water pressure when entering the water. Unstable, the sprayed water column is irregular, which will affect the quality of non-woven fabrics
In order to better ensure the product quality, the worn jet strips are generally discarded, so the jet strips of existing hydroentanglement machines have a short service life, low efficiency, and serious waste of resources.

Embodiment

[0028] The strip is made of SUS301 material, the hardness of the base material is HV300, the length L is 4.8 meters, the width W is 25 mm, and the thickness H is 1 mm. Drilling and milling are used to form a row of water spray holes. The specific size of the water spray holes is that the diameter Φa of the central hole 3 is 0.12 mm, Φb is 0.35 mm, the hole distance b is 0.6 mm, and the number of holes is 7000. Finally, PVD vacuum coating technology is used to coat a layer of TiN (titanium nitride) vacuum hard coating, in the way of hollow cathode discharge coating, with titanium (Ti) block, at 380 ° C, -80V bias, 160A bias current , 0.8 Pa air pressure, and 500 SCCM N2 flow conditions for 1 hour to obtain a 3 micron TiN coating with a surface hardness of HV2300.

[0029]Because most of the jet strips in the prior art are manufactured by traditional processes, their tolerance cannot be improved. The present invention combines the advanced vacuum vapor deposition process, and in...

Abstract

The invention discloses a vacuum hard coating water needle plate and a manufacturing method thereof. The water needle plate comprises a strip and multiple water spraying holes arranged on the strip, and the water spraying holes are provided with coatings which are formed by a chemical vapor deposition method, a physical vapor deposition method or a plasma-enhanced chemical vapor deposition method. According to the vacuum hard coating water needle plate and the manufacturing method thereof, the wear-resisting performance of the surface of the water needle plate and the water spraying holes can be significantly improved.

Description

technical field [0001] The invention relates to a novel vacuum hard-coated jet board and a manufacturing method thereof, in particular to a jet board with high surface hardness and a manufacturing method thereof. Background technique [0002] Spunlace non-woven fabric is a new type of flexible material formed by processing high molecular polymers and fibrous aggregates by physical or chemical methods. Material characteristics. The appearance and performance of spunlace nonwovens are closest to traditional textiles. It has good hand feeling, softness, water absorption and low fluff dust. Spunlace non-woven fabrics have been widely used in a variety of medical related products, such as surgical gauze pieces, surgical gowns, surgical drapes, ward sheets, pillows, etc. [0003] The manufacture of spunlace non-woven fabrics requires processes such as opening, blending, carding, and entanglement, which require different equipment to complete, and entanglement of multi-layer cott...
