Mmetụta n'oge PTFE Sintering - The Critical Stage

PTFE sintering okpomọkụ ruru 360-400°C, dị nnọọ ukwuu karịa mmalite okpomọkụ nke fiberglass thermal shrinkage, na-eme ka ogbo a bụrụ ihe dị mkpa maka arụmọrụ akụkụ.

1. Nchegbu mwepu akpọchi akpọchi na-emepụta ntụpọ akụkụ latent

Ọ bụrụ na edozie ya n'okpuru obere esemokwu, akwa fiberglass na-ada n'efu na nke ukwuu, na-ebute ogologo na obosara adịghị mma.

1. Mbelata nke abụọ na-akpata ntụpọ elu na ngbanwe akụkụ

Mgbe ị na-abanye n'ọkụ na-agwọ ọrịa, nrụgide mbelata nke fọdụrụ n'ime mkpụrụ ahụ na-ewepụta ma na-ebute mbelata teepu. Nke a na-eduga na:
