On April 9th, the price of PVC grade 5 made from electric stone material at Heilongjiang Shenghua Chemical was set at 6,100 yuan per ton, marking an increase of 50 yuan per ton. The plant, which has a production capacity of 300,000 tons per year, is currently operating at 50% capacity. Meanwhile, Hanwha Ningbo's PVCHG800/1000 type was priced around 6,850 yuan per ton, with operations expected to return to normal soon. In Liaoning, Jinhua reported that its PVC grade 5 electric stone factory accepted prices at 6,200 yuan per ton, with operations starting at approximately 5%. According to the Business Community Plastics Panel Index, the plastics index stood at 971 points on April 8, up by 2 points from the previous day. This represents a 6.18% decline from the cycle high of 1,035 points recorded on December 27, 2012, and a 3.52% increase from the low of 938 points on July 1, 2012. The index has been fluctuating in recent weeks due to ongoing supply chain challenges and rising demand in key sectors such as construction and packaging. Market analysts suggest that the continued upward trend in PVC prices is being driven by higher raw material costs and limited production capacity. With several major producers still running below full capacity, the market remains tight, and further price increases are likely if demand continues to outpace supply. Investors and traders are closely monitoring the situation, as any changes in production levels or import policies could have a significant impact on the market outlook.
Hydraulic Diaphragm Metering Pumps
As
the name suggests, Diaphragm Metering Pump using a special design and
processing of flexible diaphragm instead of the piston, under the action
of the drive mechanism to achieve reciprocating motion, complete the
suction - discharge process. Due
to the segregation of the diaphragm, the isolation between the metering
fluid and the driving lubrication mechanism is realized in the
structure. High-tech structural design and the selection of new materials has
greatly improved the service life of the diaphragm, coupled with
excellent corrosion resistance of composite materials, diaphragm
metering pumps become the main application of fluid measurement pump
type.
In the diaphragm-type metering pump family members, the hydraulic diaphragm metering pump/refineries hydraulic metering pump/Hydraulic Diaphragm Metering Pumps as a result of the use of hydraulic oil evenly drive the diaphragm, to overcome the mechanical direct drive mode under the pump diaphragm too concentrated shortcomings, to enhance the diaphragm life and working pressure ceiling. In order to overcome the single diaphragm metering pump may occur due to damage caused by the diaphragm damage, and some metering pumps equipped with a diaphragm breakage sensor to achieve the diaphragm when the automatic chain protection; with double diaphragm structure of the pump head to further improve its safety Sex, suitable for security protection is particularly sensitive to the application.
