The beast's buzzing - foreign oligarch competition in PVC industry
Like other resource industries such as minerals, steel, and petrochemical industries, the fierce competitive environment has forced foreign PVC companies to maintain their competitive advantages through strong mergers. At the beginning of the 21st century, the international PVC market has already formed a pattern of oligopolistic competition. U.S. PVC industry through mergers, reorganizations, and other means, in 2003 there were 6 large-scale producers with production capacity exceeding 1 million tons/year; Japanese PVC producers in the face of overcapacity and low device efficiency, after the 20th century 90 After the second large-scale reorganization in the middle of the decade and the beginning of the 21st century, the number of PVC manufacturers was reduced from 13 to 6.
In 2003, global 45.3% of PVC production capacity was controlled by 11 producers such as Shin-Etsu Chemicals and Formosa Plastics. Japan Shin-Etsu Chemical Co., Ltd. is the world's largest PVC manufacturer, with a PVC production capacity of 3.04 million tons, accounting for approximately 8.9% of the world's total production capacity.
After several rounds of life-and-death competition, the international PVC giants who have finally emerged have become fangs and are always looking for prey. With the increasingly oversupply situation in the domestic PVC industry, after the industry enters the era of meager profits, some weak people will emerge in front of them and become a breakthrough point for rapidly entering the domestic market. In fact, like Formosa Plastics and LG have already been deployed in the country, and their efforts are quite large. In just a few years, the scale has exceeded that of some domestic companies that have developed for decades. This can not be seen only as a kind of transfer of investment, but consciously prepared in the era of promoting the PVC industry in China to enter the oversupply earlier and faster. Once some domestic companies have experienced crisis in their operations, they will become the targets of their acquisitions, which will rapidly expand their scale and become a major force in the domestic PVC market.
Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.
The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.
Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.
With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.
