PTFE Lined Storage Tank no Tetramethylammonium Hydroxide

Hoʻopaʻa ʻia ka pahu pahu mālama ammonium tetramethyl hydroxide PTFE o RANA me PTFE, i hoʻolālā ʻia no ka hoʻokō ʻana i ka alkalinity ikaika a me nā koi maʻemaʻe kiʻekiʻe o ka uila-grade trimethylammonium hydroxide (TMAH). Hoʻohana mau ʻia ʻo TMAH i ka hoʻomaʻemaʻe ʻana i nā wafers semiconductor a me ka hoʻomohala ʻana i nā photoresists, a ua maʻalahi loa ia i nā haumia e like me nā ion metala. ʻO ka inertness kemika o PTFE ke pale aku i ka pahu pahu mai ka hoʻolei ʻana i nā mea haumia, me ka mālama ʻana i ka maʻemaʻe o ka TMAH i mālama ʻia. Eia hou, ʻo ka haʻahaʻa haʻahaʻa o ka PTFE ke pale aku i ka makū a i ʻole CO₂ mai ke komo ʻana, no laila e pale aku ai i ka emi ʻana o ka manaʻo TMAH ma muli o ka hoʻomaʻamaʻa ʻana a i ʻole ka carbonation.

Hoʻohana nui ʻia ka pahu mālama i ka hana ʻana i nā kemika uila a me ka hana semiconductor. Hōʻike ʻia kona pā i loko i kahi hoʻolālā maʻemaʻe ʻole, e hōʻemi ana i ka pilikia o ke koena mea a hoʻomaʻamaʻa i ka hoʻololi ʻana i nā ʻōnaehana TMAH o nā ʻāpana like ʻole a i ʻole nā ​​kikoʻī. Eia kekahi, ua hana ʻia ka pahu me nā mea meaʻai -mea hoʻopaʻa sila, e kūpono ana i nā koi koʻikoʻi no ka -kaiapuni mālama maʻemaʻe ultra ma ka ʻoihana semiconductor. Pono kēia mea hana no ka hōʻoia ʻana i ka pololei o nā kaʻina hana papa kumu.

Nā huahana pale: PTFE laina pahu pahu no ka tetramethylammonium hydroxide, Kina PTFE laina pahu pahu no ka tetramethylammonium hydroxide mea hana, mea hoʻolako, hale hana
