Several new products for cement packaging

The white pollution caused by packaging in China is very serious, and the plastic products in packaging materials have been abandoned, incinerated and buried because of their difficulty in recovery and degradation, causing a major environmental hazard. Among them, in the case of cement packaging, the use of plastic woven bags, paper-plastic composite bags, and the like for a long period of time in the case of unresolved technologies for recycling, degradation, and paper-plastic separation have caused environmental pollution to worsen. Facts have proved that the drawbacks of unplasticized plastic woven bag packaging cement have long been recognized by experts and industry insiders, such as high permeability and easy moisture absorption, cement cementation and lowering the standard; during filling, handling and weighting Easy to leak, causing huge economic losses; cement quality can not be guaranteed, resulting in the quality of construction projects can not be guaranteed, resulting in poor quality of construction projects and so on. Therefore, the use of the new national standard must be strictly controlled and replaced by new generation packaging.
The "High-strength Pulp Composite Paper-bag Paper" series products and equipment, "Paper-plastic separator" series, and "New-style paste-bag machine" series and other new products have been successfully developed and put into the market. Among them, “high-strength pulp composite paper bag paper” has been listed as a cement packaging product advocated and recommended by the State Economic and Trade Commission. This kind of paper uses the chemical effect of the hydrogen bonding affinity of the pulp fiber itself, without any adhesive, so that the upper and lower pulps are stacked. With the combination of mesh and mesh, a layer of paper can be used to make cement bags. It is identified and tested by the relevant national authorities. Its strength is high and it is not easily broken. It is both breathable and moisture-proof. It is easy to fill and not spray. The cost and price are low, especially after use, it can be recycled and reused. It is a new product to replace plastic woven bags. The supporting papermaking equipment can be completely transformed by using the idle equipment of the original paper mill, with less investment, quick results and large profits. This is a blessing for paper mills with poor performance and sluggish production. The paper-plastic separation technology and its equipment use paper and plastic in different physical properties such as strength, toughness, and specific gravity. Through chemical processing and physical separation, the plastic and paper are completely separated, so that they are separately recycled and reused, completely solved. The problem of being unable to recycle various kinds of paper-plastic composite packaging is a contribution to China's packaging and environmental protection industry. Excludes the worries of environmental pollution caused by the use of paper-plastic three-in-one composite bags. The main contribution of the “New Type Pasting Machine” series is to realize the packaging process of mechanism paste bags instead of manual paste bags. This equipment is a horizontal double-side continuous linear design. The bag tube is positioned by the conveying mechanism and fed into the host machine. The very complicated procedures that must be completed at the bottom of the paste bag are the directional products that the relevant national ministries and commissions and the China Building Materials Packaging Association have actively advocated and integrated with the international community for many years. At present, both large-scale paste bags and medium-sized paste bags have gradually matured and are put into use.
