In the scientific research of soil, plant nutrition and ecological environment, soil solution is one of the important research contents. The soil solution is compared to the "blood circulation in the soil". It is not only the site of most soil chemical reactions and soil formation processes, but also the source of nutrients for the root system of plants. Therefore, in modern agricultural research, soil solution sampling devices are used to sample soil solutions, and laboratory research is becoming more and more frequent. The soil solution sampler is a professional instrument for sampling soil solution. It is also called a soil solution extractor, a soil solution sampler, a suction osmometer, etc., and is mainly used for collecting soil solution samples in a soil profile. What is the complete working process of the soil solution sampler? The basic composition of the soil solution sampler is a porous ceramic head and a sample collection tube. During the sampling process, we only need to place the soil solution sampler at the appropriate depth of the soil and perform periodic sampling with minimal agitation of the soil. Measurement, this time the vacuum pump will produce a vacuum in the sampler, from the soil through the ceramic head sucking soil solution into the sampler, then the extracted solution will be extracted from the collection tube, in the laboratory for chemical analysis, this is the soil The complete working process of the solution sampler. The use of a soil solution sampler to carry out sampling of soil solutions is a relatively simple, highly operational, and very useful sampling method. Its application has effectively increased the progress and efficiency of modern research on soil solution research. It is also Research workers have reduced the workload. With the development of science and technology, Topsun developed and produced a more advanced suction-type soil solution sampler, which can be used to extract different layers of soil in situ in the field, which further simplifies the soil solution sampling process and optimizes Because of the sampling effect, it has been widely used in agricultural production, scientific research and other fields, and has played an important role in the research of environmental pollution monitoring and groundwater utilization.

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.
