Recent uncertainties in the external environment have affected the bulk products. The phenol and ** in the same cogeneration facility are in a phase of conflict. It can be described as half seawater and half as flame. The domestic phenol market demand is weak and the market lacks favorable support. The negotiation continues to decline; ** The market is under the tight supply of good support, and the focus of negotiations continues to narrow. Phenol ** market overall trading situation is more tepid.
Recently, the domestic phenol market has been weakly declining, and the market lacks favorable support. The focus of East China's talks on August 22 dropped from 13,800 yuan/ton to 8,900 yuan/ton on September 8, a drop of nearly 1,000 yuan. Under the pressure of declining market prices, the domestic petrochemical enterprises' phenolic prices have fallen one after another, and have been lowered three times from August 24 to September 9. On September 8, crude oil soared, the stock market and the stock market were all red, and the market sentiment improved slightly. The domestic phenol market narrowed and the market seemed to have a stable intention, but in the afternoon Gaoqiao Petrochemical phenol led the drop, and the market's stabilized “fire†was cast off.
The ** market's recent trend is exactly the opposite of the phenol market. The recent domestic gambling market is tighter in the supply of goods and the lack of demand for follow-up games, narrower upwards, the overall magnitude is not large, more cautious. As of Thursday this week, the market reference in Jiangsu and Zhejiang ** was 9650-9750 yuan/ton. At present, the port inventories are at a low level, especially in Ningbo, where spot resources are bleak. It is still the best support for the current market. In the middle and later quarters, as the arrival of ports arrives, the market supply may be supplemented.
But can a big fire ignite the passion of the ketene market? At about 22:50 on September 8, a smelter accident occurred in the public-engined cryogenic tank area-olefin pipeline of Shanghai Secco Petrochemical Co., Ltd., located in the Shanghai Chemical Industry Park. Affected by this, Gaoqiao Petrochemical's 200,000-ton/year phenol-ketone plant was shut down for two weeks. Currently, the downstream Sinopec Mitsui Bisphenol A plant is temporarily unaffected. Follow-up should pay attention to the supply of raw materials propylene.
Although today's domestic petrochemical companies have seen a downward adjustment, ranging from RMB 150-250/ton, but under the influence of this unexpected event, the domestic phenol and ** markets showed slight improvement in confidence on the last trading day before the holiday. A slight increase in bullishness. The price of today's offer has obviously increased, and follow-up can continue to rise, still need the guidance of market news after the holiday. Zhuo Chuang believes that after the holiday, the domestic phenol market will stabilize or narrowly rise with the benefit of this device. However, Yanshan Petrochemical's western region will resume its restart next week (mid-term), and the impact on the market mentality will still need to be followed up. ** Follow-up attention to the port arrival situation and downstream demand follow-up, whether the market can successfully break through the million yuan, still need to follow up.
Double-color Geomembrane is one kind of Hdpe Geomembrane with two side in different color. This Geomembrane liners can be used as Aquaculture, Landfill Water, Treatment System , Mining etc, area.
Black and White geomembranes offer the advantages of both a light reflective white surface and a black damage detection layer.
The liner`s UV resistant white surface reflects light – minimizing associated heat absorption by as much as 50% – and thus reducing the potential for membrane wrinkling due to thermal expansion and contraction. Traditional black HDPE geomembranes can reach temperatures of 160°F or more and experience thermal expansion exceeding 1% depending on temperature swings.
Visual inspection of the liner for damage is greatly improved. Damage is indicated by any scarring beyond the white, light reflective layer as the contrasting black primary layer is clearly exposed.
The following parameters based on the GRI GM13 for your reference.

Geomembrane Main Application
Aquaculture:
Using the geomembrane anti-seepage feature;
Geomembrane liners can be used as fish ponds, shrimp pond, and other aquaculture.
Landfill:
HDPE geomembrane is the most widely used in landfill anti-seepage engineering material,
The use of main parts of the bottom of the landfill liner, landfill sealing cover, leachate regulating pool liner, etc.
HDPE geomembrane structure with smooth surface and textured surface, suitable for different sites.
Water Treatment System:
Geomembrane is applied to the adjustment of the power plant and sewage treatment plants pool;
and a series of water treatment systems.
