Bên cạnh các loại thiết bị phun cát, Growell Việt Nam cũng cung cấp vật liệu phun cát xử ý bề mặt công nghiệp, như hạt bi thép, hạt oxit nhôm, hạt thủy tinh hay hạt bi inox. Từ đó đáp ứng được nhu cầu làm sạch đa dạng của khách hàng. Từ việc làm sạch, tẩy rỉ, loại bỏ sơn cũ cho đến việc tạo nhám, chuẩn bị bề mặt trước khi sơn.

Ưu điểm của vật liệu phun cát

Vật liệu phun cát được sử dụng rộng rãi trong ngành công nghiệp phun cát vì nó quyết định bề mặt cuối cùng sau khi phun.

Khác với cát phun truyền thống, hạt mài phun cát không tạo ra lượng bụi đáng kể. Hàm lượng silic trong hạt mài phun cát ở dưới 1% là mức an toàn do tổ chức OSHA công bố. Từ đó giúp đảm bảo sức khỏe người vận hành và an toàn môi trường cho những người xung quanh.

Hơn thế nữa, vật liệu phun cát cung cấp khả năng làm sạch nhanh chóng. Chúng có độ cứng phù hợp nên khi va chạm với bề mặt không bị vỡ ngay thành bụi. Chính ưu điểm này cũng giúp hạt mài phun cát có thể tái sử dụng nhiều lần. Từ đó tiết kiệm chi phí cho doanh nghiệp.

Hạt oxit nhôm

Hạt oxit nhôm có thành phần chính là Al2O3, có độ cứng cao từ 8 – 9 Mohs. Đặc tính sắc nét của oxit nhôm giúp nó loại bỏ nhanh rỉ sét và tẩy sơn cũ trên bề mặt. Hình dạng đa cạnh giúp làm sạch nhanh hơn, tiết kiệm thời gian xử lý bề mặt.

Hạt oxit nhôm được sử dụng chủ yếu trong hệ thống máy phun cát khí nén. Đặc biệt là tủ phun cát. Áp suất phun của tủ giúp chúng bền hơn và tận dụng tối đa khả năng tái sử dụng của oxit nhôm.

Hạt bi théphạt thép là vật liệu phun cát kim loại được sử dụng phổ biến nhất. Bi thép có dạng hình cầu còn hạt thép có dạng đa cạnh.

Xử lý bề mặt bằng hạt bi thép có thể làm tăng áp suất bề mặt của phôi kim loại và cải thiện khả năng chống mỏi của phôi. Việc sử dụng hạt bi thép để xử lý bề mặt phôi kim loại có đặc điểm là tốc độ làm sạch nhanh. Độ cứng của chúng rất lý tưởng cho việc làm sạch bề mặt vì khả năng tái sử dụng cao. Các góc cạnh và các hình dạng phức tạp của hạt thép có thể được làm sạch đồng đều và nhanh chóng, rút ​​ngắn thời gian xử lý bề mặt.

Hai loại hạt mài này cũng có thể được trộn với nhau theo tỉ lệ thích hợp để mang lại hiệu ứng bề mặt như mong muốn.

Cát thủy tinh

Cát thủy tinh không phải là loại vật liệu phun cát có khả năng tẩy rỉ mạnh mẽ như oxit nhôm. Tuy nhiên, nó rất thích hợp cho các ứng dụng làm sạch hay đánh bóng inox, loại bỏ bavia mỏng mà không làm hỏng vật liệu nền. Hình dạng cầu cảu cát thủy tinh tạo ra một lớp hoàn thiện mịn hơn, đồng nhất với thẩm mỹ cao.
