Tin groove sealing is destroyed again；3) product chemically reacted can not only deposit on a glass, can also be deposited in gas piping, mesh
It just needs to clear up gas piping later within first many glass works's continuous coatings 6 ~ 40 hours, since pipeline is located inside plating diaphragm,
It needs to plate diaphragm integrally to extract out and could clear up from molten tin bath, then turns back to molten tin bath again, restore plated film production, frequent cleaning is made
At frequent seal break-off, keep production loss huge；4) plate the gap between diaphragm and rectangular opening after although plating diaphragm is in place
It is stifled with heat preservation tampon, but it is difficult to ensure thorough sealing.Further, since temperature is higher in molten tin bath, the steel construction of diaphragm is plated for protection,
Plating diaphragm also has water cooling, and water cooling can make glass tape cool down, and the low film that is unfavorable for of glass tape temperature is grown.
