摘要： PURPOSE:To move a carrier to another place to utilize it and to recover the settled carrier by packing the carrier consisting essentially of at least porous hydrated calcium silicate carrying hydrogen peroxide in a screen or perforated vessel and bringing water contaminated with phytoplankton, etc., into contact with the carrier. CONSTITUTION:The carrier consisting essentially of at least porous hydrated calcium silicate carrying hydrogen peroxide is packed in a screen or perforated vessel, and water contaminated with phytoplankton, etc., is brought into contact with the carrier to decompose the phytoplankton over a long period of time while avoiding the rapid decomposition reaction by hydrogen peroxide. Consequently, only the phytoplankton as the contamination source for water is effectively removed. Furthermore, the carrier still having purifying capacity after temporary use is moved to another place and reutilized in water purification, and the carrier can be recovered without itself being settled on the sea bottom.

摘要： PURPOSE:To reinforce the body of a panel and enhance its physical property by applying coatings to the surface of panel prior to shipment from factory, and sending the coated panel to the drying stage to be dried. CONSTITUTION:Coatings are applied to the surface of each panel prior to shipment so as to make a coated panel. This is sent to the drying stage to harden the coatings, and also the body of the panel is dried forcedly to accomplish a dried panel. This dried panel is transported to the construction site of a building and fixed to the structural mass for building to constitute a wall. Provision of a coating film prior to shipment in this manner provides well protection of the panel body. Leading the coated panel to the drying stage till shorten the hardening time of coatings, and water contained in the panel body evaporates to accomplish a panel with low water content, wherein the physical property is well enhanced.

摘要： PURPOSE:To simultaneously remove residual effective free chlorine and malodoruos taste with a single material by using the porous purifying material for potable water formed by incorporating calcium sulfite into a calcium silicate hydrate for purification of water. CONSTITUTION:The porous purifying material for potable water is formed by incorporating the calcium sulfite into the calcium silicate hydrate. The method thereof consists in kneading main raw materials, such as siliceous raw materials and calcareous raw materials, and water to prepare a water slurry. After the water slurry is foamed with foaming agents, such as metal aluminum powder and is cured, the slurry is cured by autoclave curing to obtain the porous mixture incorporated with the calcium sulfite in the calcium silicate hydrate. The residual effective free chlorine and maloclrous taste are simultaneously removed with the single material by using such porous purifying material for potable water, by which the safe and tasty water is obtd.

摘要： PURPOSE:To obtain the hydrogen peroxide carrier with the duration of reaction increased and capable of sufficiently diffusing in water and efficiently purifying water by impregnating a porous granular body contg. a trace of iron (except hydrated calcium silicate) with hydrogen peroxide. CONSTITUTION:The porous granular body contg. a trace of iron (except the porous granular body of hydrated calcium silicate) is impregnated with hydrogen peroxide. The hydrogen peroxide is absorbed in the void of the body at this time. When the body is placed in water contaminated with the red tide, etc., hydrogen peroxide is gradually liberated and allowed to react with the plankton and suspended dust in the water to generate active oxygen, and the carrier is floated or sunk as the oxygen is attached to or detached from the carrier. Meanwhile, a part of the hydrogen peroxide generates OH radical by the Fenton reaction with iron ion to increase the oxidizing force. Consequently, the duration of reaction is increased, hydrogen peroxide is sufficiently diffused, and phytoplankton, etc., are efficiently exterminated.

摘要： PROBLEM TO BE SOLVED: To resolve the coincidence effect of an aerated lightweight concrete(ALC) panel and improve the sound insulating property and sound absorbing property by connecting an inorganic porous sound absorbing material to the ALC panel. SOLUTION: An inorganic porous sound absorbing material having the center frequency in the range of 315-800Hz, the vertical incidence sound absorption coefficient of 0.55 or above and its peak of 0.65 or above, continuous bubbles, and the density of 0.25-0.40 is connected to an ALC panel to form a sound absorbing/insulating ALC panel. The area of the inorganic porous sound absorbing material may be 50-90% of the area of the ALC panel. The sound insulating property is further improved when an air layer is provided in the middle. Water slurry is formed from a silic acid raw material or a calcareous raw material, a foaming agent is added, it is foamed and hardened, it is put into an autoclave, and it is cured in the high-temperature, high-pressure saturated steam atmosphere to manufacture the inorganic porous sound absorbing material.
