The washing liquid is mainly composed of the following raw materials in parts by weight: 10 to 35 parts of paint film protective agent, 3 to 15 parts of luster-enhancing / lubricating conditioning agent, 2 to 18 parts of ionic liquid, 5 to 32 parts of surfactant, 4 to 16 parts of auxiliary surfactant, 0.1 to 5 parts of scratch filler, 0 to 10 parts of deionized water, and 0.01 to 0.3 part of essence. The selected ionic liquid and surfactant can generate a synergetic effect, under the help of a co-emulsifier, a thermally-stable micro-emulsion system can be formed, the system is stable, the dirt removing performance is greatly improved, and the organic attachment such as bird manure can be easily removed by the provided washing liquid.

The invention relates to a natural surface active agent for cleaning fruits and vegetables, which is designed for overcoming the defects that the prior cleaning agent has non-thorough secondary cleaning, is harm to a human body after long terms of use, is not easily degraded, can cause secondary pollution, and the like. The natural surface active agent is prepared from the following components by weight percent: 10-40 percent of active matter extract of Chinese soaphberry with the concentration of 30-40 percent, 10-40 percent of alkyl poly-glycosides (APG) with the concentration of 47 percent, 10-30 percent of ginger extract with the concentration of 5 percent, 0.1-0.5 percent of EDTA, 0.3-1 percent of sodium chloride, citric acid and appropriate water. The method comprises the following steps: adding 20 percent of deionized water in a reaction vessel; heating to 35-40 DEG C, then sequentially adding APG, the active matter extract of Chinese soaphberry, the ginger extract and the EDTA, and fully mixing and stirring evenly during addition; adding appropriate citric acid; cooling to room temperature; adding appropriate sodium chloride, fully stirring for 0.5 hour and aging for 1.5 hours to obtain finished product; and bottling for leaving factory. The main components of the natural surface active agent are natural products and derivatives thereof, and the invention has the advantages of good cleaning effect, no residual, easy degradation, no stimulation to skin, no side effects, no secondary pollution to environment and environmental protection.

A modular light unit for illuminating a hazardous underwater environment includes a housing having a front portion with a light transmissive window and a back shell portion which enclose a layered lighting assembly. The layered lighting assembly includes a PCB with an array of LEDs mounted thereon with the LEDs in thermal communication with a bottom surface of the PCB. A thermal bridge abuts the bottom surface of the PCB on one side and a heat sink on the other. A thermally conductive potting material fills spaces between the heat sink and the back shell portion. An underwater connector provides releasable connection to an electrical cable for providing power to drive the plurality of LEDs. A quick-release mechanical fastener is attached to the housing for releasably attaching the modular light unit to a support structure installed within the hazardous underwater environment.

The invention discloses a peelable nano-grade decontamination coating. According to mass volume percentages, the coating comprises but not limited to 1-30% of polyvinyl alcohol, 0.3-12% of nano-TiO2, 0.7-13% of a detergent, and at least one auxiliary agent with which polyvinyl alcohol can be dehydrated and a peelable polymer film can be formed. According to the peelable nano-grade decontamination coating provided by the invention, with the added TiO2, and with the effective combination of the auxiliary agents, the formed polymer film has the advantages of easy peeling, large tensile strength, and breakage preventing. A decontamination effect is substantial. In prior art, nuclear-contaminated solid surface and solid surfaces contaminated by some other substances cannot be washed by using large amount of water, and a decontamination amount is low. With the coating, the defects are solved. When the product is used in decontamination, a post-treatment garbage amount is low, and post-treatment cost is low. The characteristics are outstanding compared to those of prior art.

A solid particle for washing and the washing method using the same are provided. The solid particle is a polymer solid particle, wherein open pores are distributed on the solid particle surface. The washing method using the solid particle comprises steps of separating the articles to be washed with the solid particles, rinsing the articles to be washed and drying the articles to be washed.

A fluid dispenser for germ-free fluid is described incorporating at least one material being capable of interacting via an oligodynamically active substance. The dispenser includes a metering pump and inlet and outlet valves. The fluid coming into contact with at least one oligodynamically active substance is present in the region of the outlet valve, of the inlet thereto and / or the outlet therefrom.

The invention discloses a foaming agent for a shield. The foaming agent contains the components in percentage by weight: 1.0-10.0% of alpha-olefin sulfonate (AOS), 1.0-8.0% of sodium fatty alcohol -polyoxyethyleneether sulfate (AES), 1.0-6.0% of ammonium lauryl sulfate (K12 ammonium), 1.0-6.0% of cocoanut fatty acid diethanolamide (6501), 1.0-5.0% of dodecyl dimethyl betaine (BS-12), 0.005-0.1% of fluorocarbon surfactant (FS), 0.2-5.0% of sodium nitrilo triacetate (A92R), 0.2-5.0% of ethylene diamine tetraacetic acid disodium salt (EDTA) and the balance of water. The foaming agent for the shield provided by the invention realizes high multiple foaming rate, long foam stabilizing time, nontoxicity and innocuity and is an environment friendly biodegradable product which does not contain phosphorus.

The invention relates to a liquid laundry detergent containing tea saponin and a method for preparing the liquid laundry detergent, and particularly relates to an antibacterial liquid laundry detergent containing the natural ingredient tea saponin and capable of functioning in sterilization and decontamination simultaneously and a method for preparing the liquid laundry detergent, belonging to the technical field of detergents for daily use. The liquid laundry detergent is compounded with the tea saponin having the sterilization and decontamination capabilities, an anionic surfactant and a nonionic surfactant so that the sterilization and decontamination functions are integrated; and the liquid laundry detergent is prepared from sodium alkyl benzene sulfonate, soap of fatty acid potassium, alkyl polyglucosides, sodium polyoxyethylene alcohol ether sulfate, fatty alcohol-polyoxyethylene ether, tea saponin, fluorescent whitening agent and other additives as well as deionized water. Compared with the prior art, the liquid laundry detergent containing the tea saponin has the advantages of rational formulation, obvious decontamination effect, excellent sterilization and disinfection functions and the like; and the obtained product is green, environment-friendly, safe and free of pollution.

A cordless stethoscope for use in hazardous material environments comprising a fluid tight hand held sound sensing device having a stethoscope head for sensing auscultatory sounds, a transmitter for transmitting sounds sensed by the device, a receiver for receiving transmissions from the transmitter and an ear piece for converting the received transmissions into audible sound. The housing is sized and shaped for being grasped by a gloved hand and is fluid tight for decontamination purposes. The sound sensing device may further comprise a microphone for sensing otherwise inaudible voice communications from a patient. The transmitter and receiver preferably uses magnetic induction transmissions to transmit sounds through barriers such as hazardous material suits that may be worn by clinicians during treatment of patients in possible hazardous material situations.
