It has actually currently been put on fire-fighting pipes systems in global countries, as well as likewise the quick water additive VCAR of United Carbon Chemical Company has actually been marketed in the 1970s.

A portion of PEO [( 30 ~ 100)× 10-6] can minimize the frictional resistance of water travelling through the fire pipe by more than 80%, double the variety of water, as well as transport about 60% more water with the basic typical dimension (6.35 centimeters) fire tube pipeline. If this additive is utilized in the fire snuffing out process, it can not just improve the fire extinguishing performance and likewise lessen the financial loss caused by the fire, however also ensure the individual protection of firemens due to the improved range.

This additive is a semi-fluid slim blend, which is PEO with a molecular weight greater than 500,000 (preferably 1 million to 12 million) and additionally a hoover density of (1.15 to 1.26)× 103 m3/kg, in addition to an inert company. Mix as well as also add a percentage of thickener to prepare. The carrier used is a mix of two miscible fluids or a solution of one strong liquified in one more liquid. This service is a non-solvent for PEO, however it is conveniently miscible with water; the thickener does not blend with polyethylene oxide To respond with the provider, silica gel is usually used, and also the dosage is 0-3.5% of the full weight of the additive.

In addition, utilizing this attribute of PEO, including a percent of this material (around 200 × 10-6) into the sewage system pipe can elevate the sewer flow price by 50% to 100%, and likewise enhance the drain ability of the sewage pipeline. When the pipe is seriously overloaded, consisting of high molecular weight PEO to the sewage system in the form of dry powder can make the drain pipeline still experienced when the whole lots is likewise huge.

The Main Properties of Polyethylene Oxide

1. Physical properties
1.1 Solubility

Polyethylene oxide is completely soluble in water, and its aqueous solution is neutral or slightly alkaline. High-molecular-weight polyethylene oxide can be mixed with water in any proportion at room temperature, and it becomes a viscous solution when its concentration is low. As the concentration increased, the solution gradually changed from gel-like to rubbery-elastic.

1.2 Viscosity of aqueous solution

The viscosity of polyethylene oxide aqueous solution is not only related to the molecular weight of the polymer and the concentration of the solution, but also related to the temperature of the solution, the shear rate, the concentration of the added inorganic salt, etc. The viscosity of the solution decreases as the temperature increases. For polyethylene oxide with a molecular weight of 100,000 to 5 million, when the temperature of the solution increases from 10°C to 90°C, the viscosity of the solution can be reduced by an order of magnitude. Due to the non-Newtonian nature of the aqueous solution, the viscosity of the solution decreases with the increase of the shear rate. Adding inorganic salts will decrease the dissolution temperature of polyethylene oxide and the viscosity of its solution, and the extent of the decrease is related to the type and concentration of the salt.

1.3 Cohesion

Aqueous solutions of high molecular weight polyethylene oxide, even if the concentration is less than 0.1%, show great dragging properties, and have coagulation properties for suspensions containing various fine substances. The greater the molecular weight, the greater the cohesion.

2. Chemical association
Although polyethylene oxide has good chemical stability, due to the unshared electron pair on the ether oxygen atom in the long chain of the polymer, it has a strong hydrogen bond affinity, and can form with some electron acceptor monomers or polymers. complexes. Compounds that can form associations with polyethylene oxide include maleic acid, acrylic acid, tannic acid, polyacrylic acid, polymethacrylic acid, copolymers of maleic acid and acrylic acid, naphthol and phenolic compounds, urea and thiourea wait.

3. Oxidative degradability
High molecular weight polyethylene oxide is sensitive to oxidative degradation during thermoplastic processing or when formulated into aqueous solutions. In thermoplastic processing, the melt viscosity decreases rapidly with the increase of temperature and the extension of time; the viscosity of aqueous solution at room temperature decreases with the increase of storage time, which are all caused by oxidative degradation. The presence of trace chlorine, peroxide, permanganate, persulfate and some transition metal ions (such as Cu + , Cu 2+ , Fe 3+ and Ni 2+ ) will accelerate the rate of oxidative degradation.

In order to inhibit oxidative degradation, some stabilizers are usually added in thermoplastic processing or aqueous solutions. For example, addition of phenothiazine, butylated hydroxytoluene or butylated anisole at 0.01 % -0.5% by weight of the polymer is effective. Adding 5%-10% (weight) of anhydrous isopropanol, ethanol, ethylene glycol, propylene glycol, etc. to the aqueous solution can reduce the rate of oxidative degradation. Divalent manganese ions (Mn2+) at a concentration of 10-5% -10-2% (weight) in aqueous solution are also effective stabilizers. However, if there is no oxidizing agent in its aqueous solution and it is used in neutral or weakly alkaline places, the solution will be stable in a short period of time (1 day), and the viscosity of the solution will not change basically.

Advantages of Using Polyethylene Oxide

1. Since both the water coating process and glass tube cleaning work use water, the cleaning and drying of glass tubes in the production process of fluorescent lamps, the coating of phosphor layers and their drying can be combined on one washing-drying-coating combined machine to quickly Finish. This not only makes the production process compact and improves the production efficiency, but also reduces the breakage rate of the glass tube due to the reduction of the number and process of loading, unloading and transfer.

2. The water coating process using PEO as the adhesive is not affected by the environment and temperature, and the production is stable.

3. The phosphor water coating using PEO as binder can increase the viscosity of phosphor paste by about 3 times, and it does not contain impurities. The prepared phosphor paste does not produce air bubbles and will not deteriorate during long-term storage.

4. The use of PEO can improve the phosphor paste preparation process and phosphor layer coating process, which can reduce the thickness difference of the phosphor layer at both ends of the fluorescent tube to less than 5%, that is, if the light transmission current at the upper end (thin end) is 100μA, Then the light transmission current at the lower end (thick end) is greater than 95μA.

5. The phosphor water coating using PEO as the adhesive can make the phosphor layer uniform and dense (delicate), without bright spots, streaks (black and white prints) and pinholes and other defects, and can make the fluorescent lamps in the production process The powder removal rate is below 1%, and the luminous flux and lumen maintenance rate of the lamp are not inferior to the best level of the organic solvent powder coating process.

6. The water slurry powder coating method is to use deionized water (or distilled water) instead of traditional butyl acetate as a solvent, and use water-soluble high-molecular polymers instead of traditional nitrocellulose as a binder to prepare fluorescent powder. Suspension to coat the method of phosphor layer. For the rare earth tri-based toner, non-ionic high molecular polymer-polyethylene oxide is used as a temporary binder in the water slurry powder coating process. The binder decomposes at a low temperature and begins to decompose at 2000°C. After reaching the decomposition temperature, it decomposes from the polymer to monomers, and these monomers run away in a gaseous state. Therefore, the use of polyethylene oxide as a temporary binder can ensure that the formed glass tube is completely baked out of the binder during the tube baking stage, and the glass tube is not deformed, which prevents the formation of a black light-absorbing film layer on the phosphor layer. .
