Ss Spunbond Nonwoven Production Line
Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or mechanical netting, and then undergo hydroentangling, needle punching, or hot rolling reinforcement, and finally finishing The resulting non-woven fabric. A new type of fiber product with soft, breathable and flat structure. The advantage is that it does not produce fiber debris, is strong, durable, silky soft, and has a cotton feel. Compared with cotton fabrics, non-woven bags are easy to shape, and It is cheap, durable, and disposable. Insulating and conductive. Softness and stiffness. Density and expansion. Isotropic, anisotropic. Filterability, breathable and impermeable. Elasticity and stiffness. Light, loose and warm. Thin as a cicada's wings, thick as felt. Waterproof and breathable. Ironing, stitching, and compression molding. Flame retardant and antistatic. Water-permeable, waterproof, abrasion-resistant, and flocking. Wrinkle resistant, good elasticity, high moisture absorption, water repellency. SS non-woven fabrics are mostly used in sanitary materials, so in the mechanical design, the SS machine tends to make the non-woven fabric softer, and the ss can also be processed to become more rigid and suitable for packaging materials.

A total of 22 sample production and distribution companies were involved, 49 batches of samples were sampled, and 33 batches passed the inspection. The 16 batches were unqualified and the product quality pass rate was 70%.
The main problems with the quality of water meters are the unqualified projects such as the demarcation flow and the low flow rate difference. The demarcation flow and the small flow rate error are unacceptable, which directly leads to the inaccurate reading of the water meter. If it is a positive error, the water meter is fast. If it is a negative error, the water meter is slow.
For the main quality problems found in spot checks, the Shaanxi Provincial Bureau of Quality and Technical Supervision will instruct the city's quality and technical supervision departments to strictly follow the requirements of the relevant laws and regulations such as the product quality law, and deal with enterprises that fail to meet the quality requirements during the random inspection process in accordance with the law, and supervise the enterprises within the time limit. Reorganization. It will continue to follow up and spot check the quality of water meter products to promote the continuous improvement of the overall quality level of the industry and create a comfortable consumer environment for consumers.
Recently, Shaanxi Bureau of Quality Supervision based on the requirements of the relevant standards in the “Implementation Rules for Water Meters Quality Supervision and Spot Checkingâ€, appearance, seal, total size, screw connection, maximum allowable error, technical characteristics, pressure test, measurement characteristics, pressure of water meter products Loss, basic functions (display function, prompt function, control function, protection function), and power supply impact were examined on 10 items.
