Abstract: A non-methane total hydrocarbons analysis apparatus and method are introduced. The analysis apparatus includes a six-pass valve, quantification ring, first stored gas pipe, second stored gas pipe, multi-pass valve, molecular sieve filling pipe, first air source, and detector. The six-pass valve and the multi-pass valve are configured to have a load status bit. A gas under test passes through the molecular sieve to remove non-methane total hydrocarbons such that the treated gas functions as a background gas for filling the first stored gas pipe and the second stored gas pipe. The six-pass valve and the multi-pass valve are configured to have an entered sample status bit such that zero-grade compressed air drives the gas inside the second stored gas pipe, quantification ring, and first stored gas pipe to enter the detector. The background gas inside the second stored gas pipe and the second stored gas pipe provides a baseline.

Abstract: An ultraviolet absorber formulation and a method of preparing the same. The ultraviolet absorber formulation comprises a zinc oxide powder and a transparent coating on surfaces of the zinc oxide powder, thus forming a core-shell structure. The ultraviolet absorber is prepared by wet chemical surface modification. A zinc oxide powder is dispersed by media or non-media milling to provide a slurry of zinc oxide. The zinc oxide slurry is subjected to a coating process to deposit a transparent coating, thus giving the ultraviolet absorber.

Abstract: The invention provides a tape film backing including a mixing layer comprising 40-60 parts by weight of PE and 60-40 parts by weight of EPDM rubber and a PE layer. The invention also provides a tape with an adhesive layer coated on the mixing layer or the PE layer of the tape film backing. The tape and the film backing is a halogen-free eco-material possessing superior physical properties as well as fine electrical insulating properties.

Abstract: An electrical insulation tape, film backing thereof, and method of manufacturing the film backing. The film backing comprises about 20 to 80 parts by weight of polyethylene, about 80 to 20 parts by weight of EPDM rubber, about 0 to 30 parts by weight of fillers, 0 to 50 parts by weight of flame retardant, and about 0 to 20 parts by weight of processing aids. The film backing has physical properties similar to PVC film backings, and thus can replace the PVC film backing used in the electrical insulation tape.

Abstract: The present invention provides a process and apparatus for treating contaminated gas. A contaminated gas containing volatile organic compounds is continuously introduced into a reactor to allow the gas to contact a metal oxide catalyst and an oxidant for a period of time. The concentration of the volatile organic compounds can be thus reduced. The treated gas is then continuously emitted from the reactor. The concentration of the organic compounds of the emitted gas and/or the concentration of the oxidant are continuously monitored, and the oxidant feeding amount is controlled according to the monitored concentration. By means of the process of the present invention, volatile organic compound-containing waste gas with high humidity can be effectively treated, and the utility rate of the oxidant can be increased.

Abstract: A method and apparatus for treating an exhaust gas containing volatile organic compounds. The method includes the steps of: introducing an exhaust gas into a wet scrubber, so that the organic pollutants in the exhaust gas are absorbed by a scrubbing water; pumping the scrubbing water containing the organic pollutants into at least one oxidation tank, thereby causing oxidation reaction between the organic pollutants and an oxidizing agents containing ozone; and introducing the scrubbing water after the oxidation reaction into the wet scrubber. The oxidizing agent further comprises hydrogen peroxide.

Abstract: The invention discloses a method for processing alkene-containing exhaust gas. It is a combination of ozonic and biological processes which mainly deal with exhaust gas mixtures having alkene-containing (C—C double bond) organic exhaust gas (such as alkene, acrylic acid) and other volatile organic compounds (such as ketone, alcohol, BTEX, and others). Since exhaust gas containing C—C double bond is difficult to dispose of, the method for processing exhaust gas presented in the invention utilizes ozone to completely decompose or transform the organic contaminants with C—C double bonds into intermediate products. The organic contaminant can then be treated in the biological process and converted into non-toxic substances. This method does not require large-sized biological process equipment, and the residual ozone is oxidized and degraded in the bio-filter.

Abstract: A method for automatically detecting waste gas. The waste gas is led into a multiple switching valve through which the waste gas is sampled. Then, the waste gas sample is conveyed to an empty column and/or a chromatographic column, via the multiple switching valve. Then, the total hydrocarbon content of the waste gas sample is measured when the waste gas sample is conveyed to the empty column, and the waste gas sample is separated for measuring individual volatile organic compound concentrations of the waste gas sample when the waste as sample is conveyed to the chromatographic column.
