## 2014년 3월 2일 산업안전산업기사 시험 문제 해설 (1번 정답)

**문제:** 페인트 스프레이 도장 작업 중 발생할 수 있는 정전기 대전 유형은 무엇일까요?

**선택지:**

1. **분출대전, 충돌대전 (정답)**
2. 충돌대전, 마찰대전
3. 유동대전, 충돌대전
4. 분출대전, 유동대전

**1번 선택지가 정답인 이유:**

페인트 스프레이 도장 작업 중 발생하는 정전기 대전은 다음 두 가지 유형으로 나눌 수 있습니다.

**1. 분출대전:**

* 페인트 용액이 노즐에서 분출될 때 발생하는 정전기 대전입니다.
* **페인트 입자와 분사 공기의 마찰**로 인해 발생합니다.
* **대전된 페인트 입자는 서로 밀착**되어 도장 작업에 영향을 미칠 수 있습니다.

**2. 충돌대전:**

* **분출된 페인트 입자가 도장 대상에 충돌**할 때 발생하는 정전기 대전입니다.
* **도장 대상의 재질과 페인트 입자의 재질**에 따라 발생 정전기 양이 달라집니다.
* **충돌대전은 도장 작업의 효율성을 저하시키고, 불량률을 증가시킬 수 있습니다.**
