Tổng quan và nguyên lý thử<\/h3>\n

Shanghai Modern BHY-I<\/strong> dùng cho phép thử độ lõm của lớp phủ có biến dạng dẻo. Khối tạo vết lõm được đặt trên màng sơn, sau đó chiều dài vết lõm dư được quan sát bằng kính hiển vi chính xác và màng đánh dấu trong suốt.<\/p>\n

Thiết bị không phù hợp với sơn có biến dạng đàn hồi vì vết lõm có thể phục hồi hoặc giảm đáng kể sau khi bỏ tải.<\/p>\n
