Pepa PTFE i hoʻololi ʻia me ke kāʻei ʻana o ka lole i ulana ʻia

Nā Mea Pono: Hoʻololi ʻia ka resin PTFE ma ke ʻano he kumu kumu, me ka lole i ulana ʻia ke aniani e like me ke kākoʻo. ʻO ka PTFE i hoʻololi ʻia he 40% maikaʻi ka hoʻoheheʻe ʻia ʻana, e maʻalahi ke komo ʻana i loko o nā pores ʻekolu -o ka lole wili.
Kaʻina Hana: Hoʻohana ʻo RANA i ke kaʻina hana "wela-press melting", me ka hoʻohana ʻana i ka wai kiʻekiʻe o ka PTFE i hoʻololi ʻia no ka hoʻokō ʻana i ka "hoʻopiha piha" o ka resin i loko o ka lole i ulana ʻia (ʻoi aku ka nui o ka hoʻopiha ʻana ma mua o a i ʻole like me 95%), me ka lining Sheet porosity I lalo a i ʻole like me 0.03% (ʻoihana ʻoi aku a i ʻole like).

Core: ʻO ka hui pū ʻana o ʻekolu-dimensional reticular structure of glass knitted fabric and high filling property of modified PTFE forms a "gap-free" composite layer, e hana ana i ka impermeability (permeability emi mai a i like paha me 0.0003g/m²·lā) a me ka ikaika haehae (Oi aku a i ʻole like me ka liʻiliʻi o ka ʻoihana 90N.
Pōmaikaʻi: Hōʻoia ʻia e kahi hui loea Iapana, ʻaʻole ia e hōʻike i ke komo ʻana ma hope o 3 mau makahiki o ka hoʻoinu ʻana i loko o ka bromine wai (highly permeable medium) (ka lining Sheets leak ma hope o 1 makahiki), me kahi pae pale wela o -200 degere a 280 degere a me ka pae kaʻina alakaʻi honua. Ma ke ʻano he lālā o ka China Semiconductor Industry Association, hoʻololi ka huahana i ka -ʻoi aku ka maʻemaʻe o ka mālama ʻana i ka wai bromine (e laʻa, semiconductor wafer cleaning).

Nā Manaʻo Hoʻohana: Hoʻohana ʻia i loko o nā pahu hoʻopaʻa a me nā pahu kaʻa no ka media permeable loa (e laʻa, wai bromine, chlorosulfonic acid). Ua hāʻawi ia i nā hāʻina no SMIC a me Qiaoli Chemical (Taiwan, Kina), e hōʻoia ana i ka maʻemaʻe maʻemaʻe (maʻiʻo ion metala ʻoi aʻe ma mua a i ʻole like me 0.05ppb) a kōkua i nā mea kūʻai aku e hoʻomaikaʻi i ka maikaʻi o nā mea kiʻekiʻe -hopena.

Nā huahana pale: ʻO ka pepa PTFE i hoʻololi ʻia me ke kākoʻo ʻana o ke aniani i ulana ʻia, ua hoʻololi ʻo Kina i ka pepa PTFE me ke aniani i ulana ʻia i nā lole kākoʻo, nā mea hoʻolako, nā hale hana.
