The invention discloses a water-based metal detergent which is composed of the following components in percentage by mass: 1-5% of anionic surfactant, 1-10% of nonionic surfactant I, 1-10% of nonionic surfactant II, 1-10% of nonionic surfactant III, 2-5% of corrosion inhibitor, 1.5-2.2% of assistant, 20-30.3% of organic alkali, 0.3-0.83% of defoaming agent and the balance of water. The higher-turbidity low-foam surfactants are introduced to effectively enhance the cleaning effect of the detergent. The oxidation-type corrosion inhibitor and adsorption-type corrosion inhibitor are compounded to enhance the corrosion inhibition effect. The organic phosphine is used instead of inorganic phosphorus, and thus, the detergent is safe and environment-friendly, thereby implementing zero addition of nitrites, silicates, ozonosphere-consuming substances and the like. The detergent has the advantages of favorable cleaning and corrosion inhibition effects, low foam, easy rinsing, stable performance and simple preparation technique, and has important practical application meanings.

The invention relates to a super-fine-denier polyester fiber and a manufacturing method thereof. The super-fine-denier polyester fiber is mainly made of polyester through spinneret orifice melt spinning and high-speed coiling by the adoption of a grazing agent. The grazing agent at least comprises fluorine-containing polyether, and the mass of the fluorine-containing polyether is larger than or equal to 45% of the mass of the grazing agent. The fluorine-containing polyether is a random copolymer of ethylene oxide, oxirane,2-[(1,1,2,2-tetrafluoroethoxy)methyl] and epoxypropane. The structural formula of the fluorine-containing polyether is as shown in the specification. The manufacturing method of the super-fine-denier polyester fiber comprises the steps of conducting measuring, extrusion, cooling, grazing, stretching and thermal shaping on the polyester and then conducting high-speed winding, and then the super-fine-denier polyester fiber is manufactured. The super-fine-denier polyester fiber has the advantages of being soft in hand feel, high in flexibility, gentle in gloss, high in water absorbing and oil absorbing performance, density, specific surface area and heat preservation performance and the like. The development of the weaving technology and the printing and dyeing technology enables more potential features of the super-fine-denier polyester fiber to be explored gradually.

The invention relates to a coarse-denier porous polyester fiber and a preparation method thereof. The coarse-denier porous polyester fiber is mainly prepared by the steps of melt spinning of polyester through multiple spinneret holes, application of an oiling agent, stretching and winding, wherein the oiling agent at least comprises fluorine-containing polyether, the mass of which is more than or equal to 45% of that of the oiling agent, the fluorine-containing polyether is a random copolymer of ethylene oxide, [(1,1,2,2-tetrafluoroethoxy) methyl] oxirane and propylene oxide, and the structural formula of the random copolymer is shown in the specification. The preparation method comprises the steps of metering, extruding, cooling, oiling and high-speed winding of polyester, thereby obtaining the coarse-denier porous polyester fiber. The coarse-denier porous polyester fiber is endowed with soft and elegant silk light sensation. Not only does the porous polyester fiber have excellent optical property, but also a fabric has effect of thick hand feeling and good fluffiness and breathability since a large quantity of fibers cannot be arranged closely and interspaces are correspondingly enlarged.

The invention discloses a water-based metal cleaning agent. The components and their mass percentages are: 1-5% of anionic surfactant, 1-10% of non-ionic surfactant I, and 1-10% of non-ionic surfactant II. 10%, non-ionic surfactant III 1-10%, corrosion inhibitor 2-5%, auxiliary agent 1.5-2.2%, organic base 20-30.3%, defoamer 0.3-0.83%, and the balance is water. The cleaning agent effectively improves its cleaning effect by introducing a low-foaming surfactant with a high cloud point; by compounding an oxidative corrosion inhibitor and an adsorption corrosion inhibitor, its corrosion inhibition effect is improved; organic phosphine is used instead of Inorganic phosphorus, safe and environmentally friendly, has achieved zero addition of nitrite, silicate and ozone-depleting substances. The cleaning agent of the invention has good cleaning and corrosion inhibition effects, low foaming, easy rinsing, stable performance, simple preparation process and important practical application significance.
