Sss Spunbond Nonwoven Production Line
SSS: Spunbond non-woven fabric + spunbond non-woven fabric + spunbond non-woven fabric = 3 layers of fiber web hot rolled; S non-woven fabrics, SS non-woven fabrics, SSS non-woven fabrics can be produced, according to non-woven fabrics Cloth performance can be used for: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wipes, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloths Cloths, tablecloths, bed sheets, bedspreads; clothing linings, fusible linings, wadding, shaped cotton, various synthetic leather base fabrics, industrial filter materials, insulating materials, cement packaging bags, geotextiles, covered cloths, crop protection cloths, seedling cloths , Irrigation cloth, thermal insulation curtain, other space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc. Mainly used in disposable hygiene products industry, medical health industry, beauty care and other industries.In terms of environmental protection, the raw material of most of the non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded , And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bag can be reused more than 10 times, and the pollution degree to the environment after being discarded is only 10% of that of the plastic bag.

1. Turn on the power switch; then place the sample on the lower pressure plate, push the lower pressure plate into the pressure tester, and align the center;
2, according to the required measurement range of the sample, hang on the pendulum or remove the corresponding, and the alignment line on the buffer valve handle alignment line; in the description of the cylinder drum rolled up on the recording paper, this Items need only be performed at the same time;
3, start the pump, unscrew the delivery valve, so that the wheels of the lower platen left the track about 10mm; will adjust the active needle and passive needle to zero; close the delivery valve;
4, start the beam motor, so that the upper platen down to about 10mm from the sample, and then turn the handwheel on the beam, so that the upper platen and the sample surface contact; according to the test requirements, speed, slowly open the delivery valve Loading test; after the sample is crushed, close the delivery valve, and stop the pump motor, record the required load value, and lift the drawing pen; at this time unscrew the return valve, lower the lower plate, remove the pressure Broken sample; repeat the above steps to complete other test samples;
5. After the final test piece is finished, remove the debris, clean the pressure tester, and restore the original sample; after each test, register in the use record book.
In order to ensure the accuracy of the measurement results, I hope everyone can follow the above steps when using the pressure tester.
