As the second monomer for polyacetal(POM) production,1,3-dioxolane has attracted great attention in recent years due to the expansion of its application, such as the solvent for grease, dyes, cellulose derivatives, polymers and etc, the stabilizer for trichloroethane, components of photosensitiser. There are usually two processes for 1,3-dioxolane production, one uses paraformaldehyde and MEG as the feedstock, while the other starts from concentrated formalin and MEG. SL Tech has been specialized in dioxolane production since 2008 based on concentrated formalin and MEG. In detail, in presence of concentrated sulfuric acid catalyst, enriched formalin and MEG reacts with each other at 90-100oC atmospheric pressure, the resulting mixture is charged to Enrichment Unit, Extraction Unit, Heavy Components Distillation Unit and Light Components Distillation Unit in subsequence to get the finished 1,3-dioxolane product.

Ultra high molecular weight polyethylene (hereinafter called as UHMWPE) is a linear structural polyethylene (PE) with viscosity-average molecular weight of more than 1,000,000 (ordinary polyethylene molecular weight is only about 200,000-300,000).The high relative molecular weight, which has given its extraordinary performance, and makes it a new type of high performance thermoplastic engineering plastics. Due to its high molecular weight, UHMWPE almost has integrated the advantages of all kinds of plastic, with common polyethylene and other engineering plastics incomparable corrosion resistance, impact resistance, self lubrication, corrosion resistance, low temperature resistance, health non-toxic, no adhesion, non water absorption and other comprehensive performance. Especially in the transmission of solid particles, powder, slurry and gas, UHMWPE has shown a unique superiority，thereby it is called as“amazing plastic”.

There are totally four production processes for formic acid production, incl. Sodium Formate Process, Butane (light oil) Liquid Phase Oxidation Process, DMF Process and Methyl Formate Process. Among these processes, Methyl Formate Process is suggested, which makes use of methanol carbonylation by CO to yield methyl formate, and then methyl formate is hydrolyzed into formic acid product. This technology is mature and advanced, reaching international leading level. It is proved that the methyl formate plant for formic acid plant has advantages like low production cost, high product purity, superior product quality, with several technical service better than that of similar plants out of China.  SL Technology is the leading formic acid production technology provider. If you have interest in building the same style or newly designed formic acid plant in your location, please feel free to contact us to get further information you need. We can also provide production line and production technology for your already set plant.

PPC (polypropylene carbonate) is a completely biodegradable environment- friendly plastic synthesized from carbon dioxide and propylene oxide. Besides, due to its using the main source of greenhouse gases---CO2 as the feedstock, PPC not only reduces the emission of greenhouse gases, but also reduces the consumption of fossil fuel. Compared to the degradable PLA(polylactide), it has advantages of high strength, good ductility, lower production cost and etc. PPC polyol with low molecular weight are used to replace conventional petroleum-based polyether, polyester and polycarbonate polyols, while PPC with high molecular weight are employed as film products, oxygen barrier material, injection molding material and etc., especially in package industry and agriculture.

If you're seeking accurate and reliable filtration, look no further than the sintered filter disc. Renowned for its robustness and efficiency, this high- performance filtration device is crafted through a specialized sintering process. Whether you're filtering plastic melt or other challenging materials, sintered filter media stands out for its strength and durability, making it ideal for high-pressure and high-temperature environments. What is a Sintered Filter Disc? A sintered powder filter disc is a top-tier metal filter disc created by combining metal or non-metal powders under heat and pressure. This process forms a solid yet porous disc that offers uniform pore structure, excellent permeability, precision filtration, and mechanical strength. These attributes make it perfect for separating, purifying, and sieving various mediums across numerous industries. Moreover, its ability to withstand extreme temperatures and corrosive environments ensures consistent and reliable performance over a long service life. Benefits of Sintering One of the key advantages of sintering is that it maintains the uniformity of the original weave. Additionally, sintering fixes the micron rating, shape, and hole size of the mesh, resulting in a multilayered structure that supports rigidity and high strength. Sintered filter discs come in various shapes, including fan-shaped, oval, square, and round, to suit different applications. Types of Sintered Filter Discs Sintered filter discs can be classified based on the material type, including: Metal Mesh Filter Discs Pleated Filter Discs Sintered Powder Filter Discs Among these, the stainless steel wire mesh filter disc and Sintered Powder Filter Discs are the most popular, made using stainless steel mesh.
