Description
본 발명은 비이온성 계면활성제액에 탄산소다등의 탄산염과 인산(H3PO4)을 배합하여 PH 6.7의 세정액으로 제조함을 특징으로한 금속판의 세정액의 제법에 관한 것이다.The present invention relates to a method for preparing a cleaning solution for a metal plate, characterized in that a nonionic surfactant solution is formulated with a cleaning solution of pH 6.7 by mixing carbonates such as sodium carbonate and phosphoric acid (H 3 PO 4 ).
본 발명은 각종 금속판면에 묻은 녹이나 스케일 각종 유기질 부패물 지방질등을 분무세정액에 의하여 유효하게 제거세정할 수 있는 금속판용 세정액을 제공하려는데 그 목적이 있다. 일반적으로 금속표면을 세정처리함에 있어서, 세정 목적에 따라 금속표면에 발생된 검은녹, 산화철, 물때 스케일등을 제거하는데는 염산, 초산, 인산, 설포산, 구연산, 수산등을 주제로 한 산성 세정제를 사용하여 청정처리하고, 금속표면에 생긴 각종 유기질 부식물 기름이나 지방질등을 제거하는데는 가성소다, 탄산소다, 붕소등의 알카리성 세정제를 사용하여 세정한다.SUMMARY OF THE INVENTION An object of the present invention is to provide a metal plate cleaning liquid capable of effectively removing and cleaning rust, scale organic decay fat, and the like deposited on various metal plate surfaces with a spray cleaning solution. In general, in cleaning the metal surface, acid cleaners such as hydrochloric acid, acetic acid, phosphoric acid, sulfoic acid, citric acid, and oxalic acid are used to remove black rust, iron oxide, and scale scale generated on the metal surface according to the cleaning purpose. It is cleaned by using and alkaline cleaning agents such as caustic soda, sodium carbonate and boron are used to remove various organic corrosive oils and fats on metal surface.
이때 산성세제의 pH는 약 5정도의 강산이고 알카리성세제의 경우는 pH 11.8정도의 약알카리성이 보통이며 물론 비이온성 계면활성제가 부가적으로 또는 주제로 사용된다. 그러나 각종 운송기구나 공작기계 또는 도장처리할 철판등의 표면에는 산성 세정제나 알카리성 세정제의 단독으로 세정처리할 수 있을 정도로 한정된 종류의 오물이 묻어있는 경우는 거의 드물고 복합적 다양한 형태와 여러물질로 오염되는 경우가 허다하여 완전한 청정처리를 하려면 양자의 세정제를 순차적으로 사용하는 것이 바람직하다. 그러나, 그것은 매우 번거롭고 특히 산성처리후 알카리 처리시의 수순이 복잡하고 작업이 번거러워 능률적인 세정작업이 어려운 문제점이 있다.At this time, the pH of the acidic detergent is about 5 strong acids, in the case of alkaline detergents weak alkaline of about 11.8 pH, of course, nonionic surfactants are additionally or used as a subject. However, the surface of various transportation equipment, machine tools, or steel plates to be painted is rarely stained with a limited kind of soil so that it can be cleaned with an acidic or alkaline cleaner alone, and is contaminated with complex various forms and materials. In addition, it is preferable to use both cleaning agents sequentially in order to perform a complete cleaning process. However, it is very cumbersome, and in particular, the procedure in the alkali treatment after acid treatment is complicated, and the work is cumbersome, so that the efficient cleaning operation is difficult.
본 발명은 이러한 문제점을 시정하기 위하여 산성 세정제의 주제와 알카리성 세제의 주제를 복합적으로 배합하되 탄산염과 인산이 가역반응을 가질 수 있는 조건으로 배합하여 종래의 pH 5에서 pH 6.7정도로 약산성으로 하는 동시 가역반응에 따라 약알카리성의 기능을 겸하여 단일세정제로서 산성과 알카리성의 두 특성을 모두 발휘하는 광범한 용도의 금속판을 세정할 수 있게한 것이다.In order to correct these problems, the present invention mixes the subject of an acidic detergent and the subject of an alkaline detergent, but combines the carbonate and phosphoric acid in a condition that can have a reversible reaction. Depending on the reaction, it functions as a weak alkaline agent, and as a single detergent, it is possible to clean a wide range of metal plates that exhibit both acidic and alkaline properties.
본 발명을 실시예를 들어 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to Examples.
탄산소다(Na2CO3) 0.5% (중량비)Sodium Carbonate (Na 2 CO 3 ) 0.5% (weight ratio)
인 산(H3PO4) 0.5% (중량비)Phosphoric acid (H 3 PO 4 ) 0.5% (weight ratio)
NP10(노닐페 놀, C9H19C6H4OH) 10%(중량비)NP 10 (nonylphenol, C 9 H 19 C 6 H 4 OH) 10% (weight ratio)
발탄CF(1,1,l-트리클로로 에탄,CH3CC13) 25%Valtan CF (1,1, l-trichloroethane, CH 3 CC 13 ) 25%
물 64%64% of water
합계 100%100% in total
상기한 조성물중 먼저 상기한 소정량의 물에 탄산소다와 계면활성제(NP10 및 발탄CF)를 가하여 교반하여 모두 용해시키고 이어 인산을 첨가교반하여 용기에 담는다. 용기는 편의상 20리터 또는 100리터들이로 한다.Sodium carbonate and surfactant (NP10 and valdecane CF) are first added to the predetermined amount of water in the above composition, stirred and dissolved, and then added and stirred with phosphoric acid to place in a container. The container is 20 liters or 100 liters for convenience.
상기의 세정제인 노닐페놀(NP10)은 무색내지 당황색의 점착성 액체이며 약한 석탄산 냄새가 난다.Nonylphenol (NP10), which is the cleaning agent, is a colorless to embarrassing liquid with a slight phenolic smell.
보통 유기용매에 녹으며 연강에는 부식이 생기지 않는 세제이며 또한, 1,1,1-트리클로로 에탄은 무색투명의 희발성 액체이며 특유의 약한 단 냄새를 가진 것으로 주로 금속의 상온세정 및 증기세정에 사용되며 드라이크리닝용 용제, 에어졸용에 적합한 것이다.Normally, it is a detergent that dissolves in organic solvents and does not cause corrosion in mild steel. In addition, 1,1,1-trichloroethane is a colorless, transparent, rare, liquid with a characteristic mild sweet smell. It is mainly used for cleaning room temperature and steam. Suitable for dry cleaning solvents and aerosols.
본 발명의 제원은 다음과 같다.The specification of this invention is as follows.

본 발명의 세정제는 각종 금속표면에 오염된 지방질, 기름, 녹, 스케일 각종 유기질 부식물 물때등을 분무세척에 의하여 제거시킨다.The cleaning agent of the present invention removes fats, oils, rusts, scales and various organic corrosive scales contaminated on various metal surfaces by spray washing.
즉, 탄산소다액의 존재로는 pH 11.8정도의 알카리성이며 인산의 존재로는 pH 5정도이나 탄산소다와 인산의 반응에 의하여 pH 6.7정도로 되며 이때 탄산염이 탄산과 분리하여 인산과 결합하여 인산염을 만들며 따라서 약산성으로 된다. 그러나, 본 발명의 세정제의 조성물 중에는 알카리성 염류와 인산등이 배합되어있기 때문에 양자의 특성으로 인하여 알카성에 의한 탈지 및 유기질 오염물질의 제거작용이 양호하다. 또한, 인산에 의한 금속표면의 녹이나 스케일, 물때등에 제거된다.That is, the presence of sodium carbonate liquid is alkaline at pH 11.8 and the presence of phosphoric acid is pH 5, but by the reaction of sodium carbonate and phosphoric acid, the pH is about 6.7. At this time, carbonate is separated from carbonic acid and combined with phosphoric acid to form phosphate. Therefore, it becomes weakly acidic. However, since alkaline salts and phosphoric acid are blended in the composition of the cleaning agent of the present invention, degreasing by alkaline and removal of organic contaminants are good due to the characteristics of both. It is also removed from rust, scale and scale of metal surfaces by phosphoric acid.
따라서, 금속판의 부식이 없어 금속표면에 오염된 각종 불순물을 단일 세정제로 보다 편리하고 확실하게 제거처리할 수 있는 효과가 있다.Accordingly, there is an effect that the various impurities contaminated on the metal surface due to the absence of corrosion of the metal plate can be more conveniently and reliably removed by a single detergent.
