코팅제는 다양한 산업 분야에서 중요성이 더욱 커지고 있으나 실제 제조업체에서는 여전히 작업자의 경영에 의존하여 배합공정을 수행하는 실정이다. 본 논문에서는 R과 실험계획법을 이용하여 코팅제 배합 공정을 분석하기 위한 프레임워크를 제안한다. 제안된 프레임워크를 통한 분석 결과는 보다 정량적인 작업 기준 데이터를 확보하고 작업 현장에 제공함으로써 코팅제 배합 공정을 개선시킬 수 있다. 특히 정확한 배합 기준이 되는 표준 데이터의 부재로 인한 품질 저하와 원가 손실을 감소시키고, 배합 공정에서 발생한 오차 데이터에 대하여 R과 실험 계획법을 이용한 분석을 통하여 표준 보정 관계식을 도출함으로써 차후 발생 가능한 오차에 대한 대응 방안을 제시할 수 있다.

The research for coatings is one of the most popular and active research in the polymer industry. For the coatings, electronics industry, medical and optical fields are growing more important. In particular, the trend is the increasing of the technical requirements for the performance and accuracy of the coatings by the development of automotive and electronic parts. In addition, the industry has a need of more intelligent and automated system in the industry is increasing by introduction of the IoT and big data analysis based on the environmental information and the context information. In this paper, we propose an optimization model for the design of experiments based coating formulation data objects using the Internet technologies and big data analytics. In this paper, the coating formulation was calculated based on the best data analysis is based on the experimental design, modify the operator with respect to the error caused based on the coating formulation used in the actual production site data and the corrected result data. Further optimization model to correct the reference value by leveraging big data analysis and Internet of things technology only existing coating formulation is applied as the reference data using a manufacturing environment and context information retrieval in color and quality, the most important factor in maintaining and was derived. Based on data obtained from an experiment and analysis is improving the accuracy of the combination data and making it possible to give a LOT shorter working hours per data. Also the data shortens the production time due to the reduction in the delivery time per treatment and It can contribute to cost reduction or the like defect rate reduced. Further, it is possible to obtain a standard data in the manufacturing process for the various models.

Massive data occurred in a manufacturing place is able to fulfill very important roll to improve the manufacturing process. Domestic manufacturing business has been making an multilateral effort to react the change of manufacturing circumstance, but it undergoes many difficulties due to technical weakness. Coatings is a type of paint. It protect products by forming a film layer on the products and assigns various properties to those. The research of coatings is one of the fields studied actively in the polymer industry. The importance of the coatings in various industries is more increased. However, the industry still performs a mixing process in dependence on operator's experiences. In this paper, we propose a design for realtime monitoring system and data analysis verification TA to improve the manufacturing process using HW-SW integrated framework. Analysis results from the proposed framework are able to improve the coatings formulation process by collecting more quantitative reference data for work and providing it to work place. In particular, the framework may reduce the deterioration and loss cost which are caused by absence of a standard data as a accurate formulation criteria. It also may suggest a counterplan regarding errors which can be occurred in the future by deriving a standard calibration equation from the analysis using R and Design of Experiments about an error data generated in the mixing step.

본 연구는 현재 국내에서 다량 사용되는 중금속 크롬과 납이 포함된 녹색안료를 대체하기 위해 유동층화학기상증착(FB-CVD) 공정을 이용한 환경친화적 무독성 유 무기 복합 녹색안료의 개발을 목표로 하였다. 기초실험으로 여러 가지의 담체 표면특성(SEM)과 성분(EDXS)을 고찰한 결과 1차 실험담체로 CaCO3를 선정하였다, 코팅안료 배합에 있어 다양한 종류의 계면활성제를 처리한 후 제조한 녹색안료의 색상발현 실험을 한 결과 건조상태나 색상발현에서 녹색물질 배합농도에 차이를 보였으나, 음이온계면활성제를 사용한 계면활성제 3이 안료 건조와 색상발현에 가장 적합하였다.

The Application of UV curing technique for poly (vinyl chloride) (PVC) floor tiles coating has improved the quality of PVC floor. Several formulations were made including acrylated oligomers based on a polyurethane were blended with reactive monomers, photoinitiators and other additives. The used oligomers are commercial aliphatic urethane acrylates. Thin films were prepared on PVC tiles by bar coating with different formulations using UV radiation. The coating resins were characterized by FTIR. The properties of UV-cured films such as gloss and adhesion were examined. The properties of UV-cured films dependent on the influence of composition and processing conditions was studied.

The purpose of this study is to present the possibility a utilization of the tertiary mudstone in Pohang as road subsoil material through pilot experiments on the road embankment structure. This mudstone is an unconsolidated rock that is distributed in the soft rock sedimentary layer, the tertiary layer of the Cenozoic, and causes physical problems such as slaking, swelling, and reduced shear strength and chemical problem like acid drainage. In order to solve various complex problems, an laboratory mixing test was conducted, and the optimal mixing conditions of the tertiary mudstone (90%), composite slag (steel making 70%, blast furnace 30%), and neutralization and coating agent treatment were derived. In order to prove its utilization, a real-scale road embankment structure was constructed and tests were conducted for each section. The pre-processing section is stable due to the design of optimal mixing conditions, while in post-processing section, natural weathering proceeded rapidly, and structural problems were concerned. Since the effect of neutralizing and coating agents was confirmed in temporary-staking section, the neutralizing and coating agents can be applied during the temporary storage period.
