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.

The purpose of the test is to provide the most reasonable beneficiation method and process flow for the mine through the optional test of ore , and propose the comprehensive recovery of the mineral processing index and associated elements, which can provide the basis for the technical and economic evaluation of the deposit.
Test personnel through a variety of modern research tools to identify the two counties when the sun temple of lead, gold and silver mine should belong to the genetic type, high-temperature hydrothermal polymetallic mine, metal mine minerals are galena, pyrite, tetrahedrite copper ore, chalcopyrite, sphalerite small amount, limonite. Gangue minerals are quartz, sericite, dolomite, iron and the like.
The occurrence state of gold and silver: natural gold is mainly distributed in metal sulfide minerals such as beryllium copper, pyrite or arsenopyrite. Natural silver is mainly distributed in galena and beryllium copper.
The main carrier mineral of gold and silver: gold carrier minerals are beryllium copper, pyrite, limonite or arsenopyrite. The main carrier minerals of silver are beryllium copper and galena.
It can be seen that there are many types of gold and silver carrier minerals, and gold and silver are relatively dispersed. Therefore, the mine is difficult to treat polymetallic sulfide ore.
In order to find a suitable process for the Sun Temple polymetallic mine in Liangdang County, the testers have done a lot of work in the process flow, and finally adopted the two processes of mixed flotation, lead-sulfur separation and preferential flotation.
