Fluoropolymer Linings Types
Fluoropolymer Linings Types
|
Sheet Lining
|
|
Lining sheet is adhered to the base item. Joints are sealed by welding work. |
|
|
|
Mold Lining
|
|
The polymer is cast directly into the base material. Used for the small parts such as valves and TEE. |
|
|
|
Loose Lining
|
|
Lining sheet or tube is inserted into the base item without adhesive.
|
|
|
|
Roto Lining
|
|
Vessel with polymer powder inside is rotated inside an oven to create a coating.
(rotating molding, PE, PFA, ETFE, etc.)
Top coat is necessary to prevent metal elution.
|
|
|
|
Roto Mould
|
|
Roto Lining Technique with metal mold. PE, PFA and ETFE.
Used for some of the small containers for semiconductor manufacturing. It performs poorly under negative pressure and is easily permeated. |
|
|
Adhesive for Lining
Adhesive for Lining
|
Rubber Adhesive
|
|
Elasticity of rubber insolates from both temperature and impact. |
|
|
|
Epoxy Adhesive
|
|
It is superior for high heat and corrosive chemicals but does not insolate from either temperature or impact. It is usually used for high temperature. |
