In January-February 2017, China's imports of titanium dioxide totaled 36,517 tons, up 38% year-on-year, of which 18,635 tons were imported in February. The following is the statistics of titanium dioxide imports since 2016:
Cumulative time (tons) Cumulative growth (%) Current value (tons) February 2017 36517 38 18635 January 2017 17882 32.5 17882 December 2016 199843 -2.1 21263 November 2016 167981 -11.9 18532 October 2016 149449 -14.4 13029 September 2016 136418 -15.7 14778 August 2016 121641 -13.5 13246 July 2016 108394 -10.9 19919 June 2016 88475 -11.1 19263 May 2016 69211 -14.7 15905 April 2016 53307 - 13.6 13107 March 2016 40200 -2.9 13738 February 2016 26462 -2.3 12963 January 2016 13499 -1.7 13499Under the dual pressure of supply-side reform and environmental protection policies, the production of titanium dioxide in China for the first time fell in 2016. In 2016, the nominal production capacity of titanium dioxide was 3.62 million tons, a reduction of 80,000 tons compared to 2015. The industry operating rate also increased from 64.99% in 2015 to 72.67% in 2016. It is expected that in the next 1 to 2 years, some small and medium-sized titanium dioxide enterprises will gradually withdraw from the market, maintaining the industry's continued upward trend.
Titanium dioxide as the real estate cycle after the general lags behind real estate for six months to a year or so, the warming of the real estate industry will make the demand for titanium dioxide broke out in 2017. Due to the increasing quality of titanium dioxide products in China, the import volume of titanium dioxide has also been declining year by year. In 2017, while the domestic downstream demand was recovering, the import volume of titanium dioxide also maintained a steady increase.
Plate and gasket are the critical part of a removable Plate Heat Exchanger. The main function of the plate is to isolate the medium and perform heat exchange. Its main materials are stainless steel (304/304L, 316/316L, 254SMO), titanium, nickel, titanium-palladium alloy, Hastelloy, etc. The sealing gasket is installed in the gasket groove around the plates to seal the periphery between the plates to prevent the fluid from leaking out, and according to the design requirements, seal part of the corner holes so that the hot and cold media flow according to their own flow paths. The structure of the plate heat exchanger consists of a fixed frame, a movable frame and corrugated plates sandwiched between the two frames. Hot and cold liquids pass sequentially through the area between the corrugated plates separated by sealed elastomer paths. To prevent leaks, good gasket elastomers are installed around the perimeter of the plates and large fastening bolts are used to hold the plates together. The structure of the plate heat exchanger makes sealing a key part of this equipment, responsible for the service life of the entire equipment. Depending on the process medium, the gasket must be chemically and/or temperature resistant. Spetech supplies seals for most existing plate heat exchangers: power industry, petroleum processing, food and beverage industry, sugar industry, chemical, pulp and paper industry. The most commonly used materials are: NBR, HNBR, EPDM, FPM (different grades). There are two basic ideas for the installation of seals: glue seals and clip seals. Clip-on washers do not require any adhesives for installation. This modification makes it possible to mount the spacers by installing clips in the grooves in the plate. As a result, the gasket is highly resistant to pressure and can be replaced quickly and easily.
