Các biện pháp phòng ngừa

Nhựa phải được bảo quản ở trạng thái ướt. Nhiệt độ tốt nhất là trên 0℃. Nhựa phải được để trong không gian kín hoặc thêm nước muối 5% trở lên nếu không sử dụng trong thời gian dài. Nên chống đông trong quá trình vận chuyển. Không đặt vật nặng lên nhựa để tránh bị va đập.

Nói chung cần có đường dẫn dòng kiềm-nước-axit-nước để xử lý. Yêu cầu nghiêm ngặt cần có ba vòng tuần hoàn trước khi đến kênh ion cuối cùng.

Cần xem xét tỷ lệ giãn nở biến đổi khác nhau để dành đủ không gian ngăn nhựa tràn và đảm bảo chiều cao mực chất lỏng thích hợp; Tỷ lệ đường kính cột phải nằm trong phạm vi hợp lý và tránh dòng điện phân cực; Sử dụng cột nhồi ướt hoặc rửa ngược để rửa sạch bọt khí bên trong lớp nhựa.

Trước khi chất lỏng đi vào cột nhựa, cần thực hiện các bước như keo tụ, lọc hoặc lọc cát để chất rắn lơ lửng không làm kẹt lỗ nhựa.

Nhựa bên trong cột không sử dụng trong thời gian dài nên được lưu trữ bên ngoài cột sau khi rửa hoặc thêm nước muối vào môi trường chịu muối trong khi vẫn giữ mức chất lỏng không bị mất nước bằng cách rửa ngược thông thường để làm lỏng nhựa trong trường hợp nhựa bị kết tụ.
