Claims (1)

플라스틱에 적량의 가스발포제, 아연화, 탄산칼슘, DOP, 안료 및 가스분산제를 첨가한 원료를 압출기에서 원주상으로 압출하면서 냉각수통 내의 성형인출 로울러에 1. 2차로 통과시켜서 부구체를 얻거나 부구형의 사출금형에 의하여 상출 성형하여 부구체를 얻는 어망용 플라스틱 부구의 제조방법.Raw materials containing an appropriate amount of gas-foaming agent, zincation, calcium carbonate, DOP, pigment and gas dispersant to the plastic are extruded circumferentially in the extruder, and then passed through the mold take-out roller in the cooling water tank to obtain a globular or spherical shape. The manufacturing method of the plastic floats for fishing nets obtained by lifting molding by the injection mold of this invention. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
