True Hearts Shine in the Face of Disaster; United as One, We Will Overcome Any Adversity

2021-07-26

Sudden, extreme torrential rainfall has plunged Xiaoguan Town in Gongyi City into floodwaters, causing extensive damage to infrastructure, farmland, and homes, as well as disruptions to power, communications, water supply, and gas services. For a time, several townships were cut off from the outside world, leaving countless residents in dire straits and facing severe shortages of daily necessities. In the face of this once-in-decades disaster, Zhang Hongwei, Chairman of Zhengzhou Phoenix Technology New Materials Co., Ltd., has not only organized internal self-help efforts but has also remained deeply concerned about the safety and well-being of his employees. Despite numerous challenges, he mobilized teams to meticulously deliver emergency supplies—such as bottled water, instant noodles, candles, lighters, flashlights, and portable chargers—to every employee’s household. These relief items have become a source of warmth and hope for affected employees at their most anxious, helpless, and desperate moments; choked voices and streaming tears are the heartfelt response to the company’s genuine care. Assuming social responsibility has always been the company’s guiding principle. Though the road ahead is fraught with obstacles and peril in the wake of such a catastrophe, compassion and sincerity will never be intimidated by hardship. The company has made every possible effort to donate large quantities of emergency supplies—including instant noodles and bottled water—to nearby villages and towns, while also providing free food and lodging for more than 60 disaster victims on its premises. To date, the company has donated relief supplies worth over RMB 80,000. With the disaster still ongoing, we will continue to demonstrate our sincerity and moral integrity through concrete actions—actions that shine brightly with dedication and compassion. July 24, 2021

Alumina bauxite suppliers will explain the applications of alumina bauxite.

2021-10-13

Alumina bauxite suppliers will now explain the applications of alumina bauxite. Its main component is alumina bauxite, which is a hydrous aluminum oxide mineral containing impurities. It is an earthy mineral with a density of 3.9 to 4 g/cm³, is opaque, brittle, poorly soluble, insoluble in water but soluble in sulfuric acid. So what are the uses of alumina bauxite? Let’s take a look.

Solder Flux Manufacturer Explains the Function of Solder Flux

It prevents re-oxidation of the surface during soldering, reduces the surface tension of the solder, and enhances soldering performance. The quality of the flux directly affects the quality of electronic products. The following section, provided by a flux manufacturer, explains the functions of flux.

Welding flux manufacturers consider submerged arc welding to be a type of arc welding. A defining characteristic of arc welding is the melting of the base metal. If the molten metal is not protected from atmospheric exposure during the melting process, the weld seam will contain excess oxides, reduced alloying elements, and increased nitrides. To mitigate the detrimental effects of oxygen and nitrogen, it is essential to shield the molten metal from the atmosphere throughout the welding process. The gases and slag produced by the submerged arc welding flux serve to isolate the liquid metal from the surrounding air.

Key insights into flux—explained by a flux manufacturer.

Welding flux manufacturers believe that welding is a highly complex physicochemical process characterized by high reaction temperatures, short reaction times, and the difficulty of achieving equilibrium at any stage of the reaction. Investigating the influence of flux composition on welding process performance remains the most commonly employed approach both domestically and internationally.

According to manufacturers of submerged-arc welding flux, submerged-arc welding is an automated welding process in which a continuous feed of welding wire generates an electric arc beneath a layer of flux. It is also known as submerged-arc automatic arc welding, or simply submerged-arc welding. During welding, the wire feeder of the welding machine automatically advances the welding wire, strikes the arc on the strike plate, and maintains a constant arc length to carry out the weld. In front of the welding wire, granular flux continuously flows out of the hopper and is sprinkled over the joint surface of the workpiece. The arc burns beneath the flux layer, melting the workpiece, the welding wire, and the flux; the molten metal forms a weld pool, while the slag from the melted flux covers the surface of the pool.

According to manufacturers of submerged-arc welding fluxes, such fluxes are generally classified into two main types: fusible fluxes (e.g., HJ350/431) and sintered fluxes (e.g., SJ101/201). Currently, some production lines equipped with submerged-arc welding machines encounter challenges in appropriately selecting between sintered and fusible fluxes. In recent years, sintered fluxes have come to account for approximately 80% of the market share, while the use of fusible fluxes has been declining. In fact, each type has its own advantages and disadvantages; when used correctly, they can help avoid many unnecessary complications.

Submerged Arc Welding Flux Manufacturers: Submerged arc welding fluxes are generally classified into two main types: fused fluxes (such as HJ350 and HJ431) and sintered fluxes (such as SJ101 and SJ201). Currently, some welding units employ submerged arc welding equipment, which presents challenges in the application of sintered fluxes compared with fused fluxes. In recent years, sintered fluxes have come to account for 80% of the market share, while the use of fused fluxes has steadily declined. In fact, each type has its own advantages and disadvantages; when used appropriately, they can help avoid many unnecessary complications.
