August 8, 2010 soil moisture monitoring results show that: in the eastern part of Gansu Province, south-eastern parts of Qinghai, Ningxia, northern Shaanxi, Shanxi, central and southern, eastern Inner Mongolia and the Loop area, local and western Heilongjiang, Jilin and other places lack of soil墒 or continued to be absent, soil shortage in the northwestern part of the mountain, northwestern part of Hebei, central and southern Inner Mongolia, etc.; soil in the northeastern part of Heilongjiang, southeastern Jilin, southern Liaoning, western Shandong, central and southern Guangdong, and most parts of Yunnan Or continue to get too wet. Most of the rest of the country's testing area is more suitable for soil moisture. After measuring soil moisture, eastern Qinghai, Shanxi and other places most of 5 to 30 millimeters of precipitation, lack of moisture in the soil improve the situation; northeastern Heilongjiang, Jilin, southeastern, eastern Liaoning rainfall of 10 to 50 mm in some areas more than 100 mm The soil is too wet or persistent. It is expected that in the next three days, there will be small to moderate rain or showery weather in most parts of China, including heavy rain in southeastern Qinghai, southern Gansu, southern Ningxia, central and northern Shaanxi, most of Shanxi, most of Shandong, and western Yunnan. Heavy rain, heavy rain in some areas. Soil shortages in southeastern Qinghai, most of Ningxia, northwestern Shaanxi, central and southern Shanxi will be improved; soil over-wetting will continue or worsen in western Shandong and western Yunnan. In addition, in the next three days, Jianghan, Jianghuai, Jiangnan, and most of southern China have high temperature of 35 ~ 37 °C. The relative humidity of 10 cm soil in Jianghan, Jianghuai and Jiangnan areas will decrease significantly, while the soil in central and southern Guangdong is too wet. The situation will improve.
HCPE Resin (coating type) Description
HCPE resin (coating
type) is a irregular resultant after depth chlorination with the low molecular
weight polyethylene (PE) . Generally the quality score of chlorine is bigger
than 65%, and it is the main film-forming substances as new generation
antiseptic paint. It has the following characteristics.
(1) Compared with the CPVC, the solubility is good,
and more resins can mix with it.
(2) Compared with the CSM, the advantage of HCPE is
single-component packaging, it do not use lead oxide, tribasic lead curing
agent containing heavy metals. There is no toxicity, and has a broader range of
applications.
(3) Compared with the chlorinated rubber, HCPE as the
base material of protective coatings retains the advantage of chlorinated
rubbers, And overcome the faults of chlorinated rubber exist unsaturated double
bond and light chemical reaction and chlorinated degradation sensitive.
(4) Compared with ordinary HCPE, the viscosity is
low, take the Tu-4 coating cup, the quality score as the toluene solution 20%,
under the room temperature determines, is not bigger than 50S; Ordinary HCPE
viscosity generally above 50S.
(5) Made of high-solids coatings, reduces the coating
cost greatly, and the coating has a fast-drying nature, and has a better compatibility
with other resins. LHCPE film features: The coating made by HCPE has a high
solid content. excellent resistance to acid, alkali , salt, etc. It have so
excellent corrosion resistance properties; can be used under 15~50°C; film
drying quickly.
