A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition. The pre-vulcanization composition comprises soluble sulfur with high S8 ring structure that is catalytically broken by a zinc dithiocarbamate. Surfactants present in the pre-vulcanization composition wets synthetic polyisoprene particles and permeates small sized sulfur and accelerator molecules into the interior of these particles thereby pre-vulcanizing the particles. The degree of pre-vulcanization is verified by isopropanol index test. The latex emulsion has post-vulcanization composition with accelerators that crosslink inter-particle region during post vulcanization cure cycle. The dipped synthetic polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds in TEM and zinc segregation at the boundaries or original particles by electron microprobe analysis. The films exhibit high tensile strength, tensile modulus, tear strength, burst pressure and burst volume.

A LCD device that receives curing light sufficiently to thereby realize approximately uniform curing of the material of the sealing member without eliminating the conductive light-blocking members. A first substrate has a display area and a peripheral area located to surround the display area. The display area includes pixels arranged regularly. The peripheral area includes a sealing member, wiring lines connected to the pixels, and conductive light-blocking members. A second substrate is coupled with the first substrate. A liquid crystal layer is formed between the first and second substrates. The sealing member is formed to overlap with the wiring lines and the light-blocking members in such a way that a non-overlapping area of the sealing member with the wiring lines and the light-blocking members is equal to 25% per unit area of the sealing member or greater.

The invention discloses an indoor test method forming an artificial hard shell layer by microbial curing silty-fine sand. Silty-fine sand is paved on slurry which is thick enough, the slurry is separated from the silty-fine sand by a seepage-proofing thin film, liquid is injected into the left side by a liquid injecting peristaltic pump until a sand layer is saturated, liquid on the right side is extracted by a liquid extracting peristaltic pump to form horizontal laminar flow, the flow velocity of liquid injection and extraction is controlled, so that liquid injection and extraction are balanced, and silty-fine sand layers are cemented and cured by MICP (microbial induced calcium carbonate precipitation) technology to form the hard shell layer. The hard shell layer has high rigidity and strength, the carrying capacity of a soft soil foundation can be multiply improved, sand consumption is greatly decreased, the hard shell layer is resistant to liquefaction, and the requirement of basic carrying capacity can be met.

Technological parameters of various stages are set through a programmable logic controller (PLC); the pole plates are fed into the curing chamber, and directly enter the rapid drying chamber after being cured; and the pole plates are cured after being dried in the rapid drying chamber. The curing chamber has the characteristics of curing uniformity, energy conservation and consumption reduction; according to the high-temperature curing technology, the curing time is shortened; the equipment utilization rate is increased; and meanwhile, the energy consumption is reduced.

The invention relates to an infrared pulse radiation heating method for curing board surface powder and equipment for implementing the method, which belong to the field of infrared technology application. The heating method uses the new concept of a medium-wave infrared pulse radiation heating unit, and pulsed high-temperature curing is performed for artificial MDF (medium density fiberboard) surface powder coatings by the aid of short-time pulsed high temperature, so that heat damage of a board surface is avoided. By the aid of a pulsed high-temperature curing accumulation effect, coated film curing time is greatly shortened, the heat absorption capacity of a board matrix is greatly decreased, and an MDF is ensured to be at the temperature lower than 100 DEG C during discharge. By the aid of the equipment for implementing the method, effective heating space and the length of a drying tunnel can be reduced, MDF surfaces in an automatic coating production line are ensured to be in the same heated state, coated films are uniformly cured, and an energy-saving effect is extremely remarkable.
