Abstract

The recycling method consists of (1) controlling pH of used cleansing water with acetic acid, (2) adding sodium hydrosulfite, hydrogen peroxide, preservative to control glue content of 40%, (3) adding locust bean gum to 40%. From this method no wastewater is produced and the wastewater treatment process is saved.

Description

How to refinish the cleaning water of printing cloth

본 발명은 날염포 세척수를 재정제 사용하는 방법에 관한 것이다. 종래에는 날염을 할 때에 원단을 투입하여 원호, 염료, 침투제, 소포제, 환원방지제 등 혼합물에 적당량의 물을 첨가 교반하여 점도가 유지되게 염호를 만들어 인날(날염을 찍는 것)을 한 연후에 100℃에서 30-40분 동안 증열하여 규착시킨 후 수세시에 세척제, 유연제, 환원방지제를 투입하여 염료와 호료를 세척하고 유연 처리 후 탈수한 뒤 건조하는 공정을 채택하고 있으나 수세시에 다량의 원호, 침투제 등이 함유된 유해한 폐수가 대량 방류되므로써 식수원과 주위환경을 크게 오염시키는 공해 발생의 요인이 되기도 하여 날염 공장에서는 많은 경비로 폐수처리 시설을 갖추어 가동은 하고 있으나 제대로 정수는 하지 못하면서 에너지와 인력이 많이 소요되는 등의 폐단이 있었다.The present invention relates to a method for refining the printing cloth. Conventionally, when printing, 100 ° C is added after adding fabric to a mixture of circular arcs, dyes, penetrants, antifoaming agents, reducing agents, etc. by adding an appropriate amount of water to make a viscosity to maintain the viscosity. It is steamed for 30-40 minutes, and then it is adopted to wash dyes and ingredients by washing agent, softening agent and anti-reducing agent at the time of washing, and dehydration and drying after washing. Due to the large discharge of harmful wastewater containing lights, it can be a cause of pollution that greatly pollutes the drinking water source and the surrounding environment.In the printing plant, the wastewater treatment facility is operated at a high cost, but energy and manpower are not maintained properly. There was a discontinuity such as that required.

본 발명은 상기와 같은 폐단을 해결하기 위한 원단을 날염 후 세척시와 탈수시 원호, 유연제, 침투제, 소포제 등 성분이 함유된 폐수를 전량 집수조에 수거한 뒤 정제조로 이송하여 초산(ACETIC ACID)으로 산도를 조정하고 하이드로설파이트(SODIUM HYDROSULPHITE), 과산화수소(HYDROGEN PEROXIDE)방부제 등 약품을 적정량 투입하여 염호를 만드는데 적합하도록 정제 후 재처리한 세척수를 염호를 만드는데에 60% 이상 활용하므로써 원호의 절감은 물론 호료의 고형분이 높아지므로 고급호료가 되어 날염호료의 최장점을 보유하게 하는 한편 세척수의 방류가 일체 없게 되므로 심각한 공해문제를 완전히 추방할 수 있도록 발명한 것으로 그 실시예에 따라 상세히 설명하면 다음과 같다.The present invention collects the waste water containing the components such as arc, softener, penetrant, antifoaming agent during printing and dehydration after printing the fabric for solving the above-mentioned waste disposal in the collection tank after transfer to acetic acid (ACETIC ACID) By adjusting the acidity and adding the proper amount of chemicals such as SODIUM HYDROSULPHITE and hydrogen peroxide (HYDROGEN PEROXIDE) preservative to make salt lake Of course, since the solid content of the paint is high, it is a high-quality paint, which has the longest point of the printing dye, and since the discharge of the washing water is not at all, it is invented to completely remove the serious pollution problem. same.

[실시예]EXAMPLE

원단을 날염 후 세척시와 탈수시 폐수에 함유된 염호 등을 허실이 없게 전량 집수조에 수거한 뒤 정제조로 이송하여 불순물을 제거하고 초산(ACETIC ACID, CH₃COOH)으로 산도를 조정한 다음 하이드로 설파이트(SODIUM HYDROSULPHITE, Na₂S₂O₄)와 과산화수소(HYDROGEAN, PERMIDE, H₂O₂), 방부제(C₆H₆O)를 적정 배합비로 투입하여 염호 60%가 되게 재처리한 세척수에 로거스트빈 검(LOCUSTBEAN GUM) 40%를 추가하여 호료의 고형분이 높아지는 고급날염 호료의 최장점을 가진 세척수를 재정제 하는 것이다.After printing and washing the fabric and dehydration, all the salt lakes contained in the waste water are collected in a collection tank without loss and transferred to a purification tank to remove impurities and adjust the acidity with acetic acid (ACETIC ACID, CH ₃ COOH). Sulfite (SODIUM HYDROSULPHITE, Na ₂ S ₂ O ₄ ), hydrogen peroxide (HYDROGEAN, PERMIDE, H ₂ O ₂ ), and preservative (C ₆ H ₆ O) were added to the wash water reprocessed to 60% of salt water. The addition of 40% LOCUSTBEAN GUM refines the wash water that has the longest advantage of high-grade printing pastes, which increases the solids content of the coatings.

이와 같은 실시예를 거쳐서 정제 되는 세척수는 날염후 수세시나 탈수시에 배출되는 원호, 염료 등이 다량 함유된 폣를 방류하지 않고 전량 수거하여 적정량의 약품만 정제조에서 보충하여 세척수로 반복해서 사용할 수 있으므로, 침투제, 유연제 등을 절감할 수 있을 뿐아니라, 색호를 만드는데에 정제된 물을 사용하면 고형분이 높아지므로 날염호의 최대 장점을 살릴 수 있어 제품의 침투성, 섬세도, 번짐 방지 등에 효과가 있는 우수한 제품을 생산할 수 있으며, 대외적으로는 폐수의 방류가 없으므로 폐수처리 시설이 불필요한 획기적인 발명이다.Washing water purified through such an embodiment can be used as a wash water by replenishing only the appropriate amount of chemicals in the refining tank by collecting the whole amount of water without discharging 폣 containing large amounts of arcs, dyes, etc. discharged at the time of washing or dehydration after printing Not only can we reduce penetrant, softener, etc., but also purified water is used to make color arc, so that solid content is increased, so we can take advantage of printing foil, and it is excellent product which is effective in penetrating, delicateness, and prevention of product. It can produce, and because there is no discharge of waste water externally, waste water treatment facility is a revolutionary invention is unnecessary.

Claims

After printing the fabric, washing and dehydrating, collect all the salt lakes in the waste water without loss and transfer them to the refining tank to remove impurities and adjust the acidity with acetic acid (ACETIC ACID, CH ₃ COOH). The logger in the wash water reprocessed to 60% salt water by adding hydrosulfite (SODIUM HYDROSULPHITE Na ₂ S ₂ O ₄ ), hydrogen peroxide (HYDROGEAN PERMIDE, H ₂ O ₆ ), and preservative (C ₆ H ₆ O) at the proper mixing ratio. How to refinish the wash water of printing cloth by adding 40% of LOCUSBEAN GUM.
