Ebe nchekwa nchekwa PTFE maka Tetramethylammonium Hydroxide

RANA's PTFE lined ammonium tetramethyl hydroxide tank nwere PTFE, e mere iji zute alkalinity siri ike na ịdị ọcha dị elu nke eletrọnịkị{{0}grade trimethylammonium hydroxide (TMAH). A na-ejikarị TMAH eme ihe na nhicha nke semiconductor wafers na mmepe nke photoresists, ọ na-enwe mmetụta dị ukwuu na adịghị ọcha dị ka ion ígwè. Inertness kemịkalụ nke PTFE na-egbochi ihe tankị ịpụpụ ihe ndị na-emerụ emerụ, na-ahụ na TMAH echekwara na-edobe ịdị ọcha ya. Na mgbakwunye, obere permeability nke PTFE na-egbochi mmiri ma ọ bụ CO₂ ịbanye, si otú a na-ezere mbelata nke itinye uche TMAH n'ihi nnabata mmiri ma ọ bụ carbonation.
