I ke ana ana, o kekahi o ka pane kumu i ka mea ana corrosive, oia ka hoohana ana i na mea kupono e ku i ka poino no ka hapa pulu o ka mea kani, ike diaphragm a i ole kona uhi ana, pahu uila a i ole na mea e pono ai.
PTFE:
ʻO ka PTFE (Polytetrafluoroethylene) kekahi ʻano o ka ʻenekini ʻenekini palupalu, māmā a me ka haʻahaʻa haʻahaʻa haʻahaʻa i loaʻa i ke kūpaʻa kino kino. He hopena maikaʻi loa ia no ke kūlana koʻikoʻi i ka hana kemika a me nā ʻoihana aila & kinoea. Eia nō naʻe, pono e hoʻomaopopo ʻia ʻaʻole pili ʻo PTFE i ka wela o ka hana ma luna o 260 ℃, ʻaʻole kūpono ka paʻakikī haʻahaʻa i ke kaula a i ʻole nā mea diaphragm.
Tantalum:
ʻO Tantalum kahi metala kūpaʻa kūʻokoʻa i hiki ke kū i nā kemika koʻikoʻi like ʻole, e lilo ia i koho maikaʻi loa no ka ʻike ʻana i nā mea diaphragm no ka media corrosive loa. Eia nō naʻe, ʻoi aku ke kumu kūʻai o ka metala a ʻaʻole i hoʻohana mau ʻia e like me nā mea ʻē aʻe. I loko o kahi ʻōnaehana kaʻina hana kemika e hoʻokele ana i nā ʻakika koʻikoʻi loa, ʻo kahi sensor kaomi i hoʻolako ʻia me ka tantalum sensing diaphragm i kūpono loa no ke kūlana e hoʻokō i ke kiʻekiʻe kiʻekiʻe o ka pale ʻana i ka corrosion.
Keramika:
ʻO ka Ceramic kahi mea metala maikaʻi ʻole e hōʻike ana i ke kūpaʻa kūʻokoʻa i ka wela kiʻekiʻe a me ka corrosion. Hoʻohana pinepine ʻia nā mea ʻike piezoresistive/capacitance me zirconia a i ʻole alumina ceramic membrane i ka ʻāpana kemika, lāʻau lapaʻau, a me nā meaʻai a me nā mea inu. He mea nui nō hoʻi e hoʻomaopopo i ka mea ʻaʻole metala, he palupalu ka ceramic no laila ʻaʻole kūpono nā mea ʻike ceramic no ka hopena kiʻekiʻe, ka haʻalulu wela a me ka noi ʻana a koi aku i ka mālama hou ʻana i ka wā e lawelawe ana.
Hastelloy Alloy:
ʻO Hastelloy kahi pūʻulu o nā ʻāpana nickel-based, ʻo ia ka C-276 e hōʻike ana i ke kūpaʻa corrosion maikaʻi loa a koho maʻamau i mea no ka diaphragm mea kani a me nā ʻāpana pulu ʻē aʻe e kūʻē i ka media corrosive. Hoʻohana ʻia ka alloy C-276 i ka hapa nui o nā ʻoihana ʻoihana kahi e hōʻike ʻia ai nā kūlana kemika koʻikoʻi a hiki ke hāʻule nā mea ʻē aʻe.
Ke kila kila 316L:
ʻO ka ʻano kila kuhili ʻole maʻamau i hoʻohana ʻia no ka diaphragm sensing he 316L. Loaʻa i ka SS316L ke kūpaʻa corrosion haʻahaʻa, nā waiwai mechanical kūpono a me ke kumukūʻai kūpono. Hiki nō hoʻi ke hoʻomaikaʻi i ka pale ʻana i ka ʻili i loko o ka ʻāina paʻakikī. Akā ʻo kona kūpaʻa ʻana i ka ʻinoʻino loa, ua kaupalena ʻia a emi iho me ka piʻi ʻana o ka mahana a me ka neʻe ʻana o ka corrosive medium. I kēlā hihia, pono e noʻonoʻo e hoʻololi i ke kila kila ma ka ʻāpana pulu a me ka diaphragm me nā mea ʻoi aku ka maikaʻi.
Monel:
Ua kapa ʻia kekahi huila nickel-based monel. ʻOi aku ka ikaika o ka metala ma mua o ka nickel maʻemaʻe a me ka anti-corrosive i nā ʻakika like ʻole a me ka wai paʻakai. Ma ke kai a me ka hoʻohana ʻana i ka monel series alloy he koho kaulana ia no nā mea diaphragm. Eia nō naʻe, ʻoi aku ka nui o ke kumu kūʻai a i kekahi manawa kūpono wale nō inā ʻaʻole hiki ke koho ʻia nā kumu kūʻai haʻahaʻa a ʻaʻole kūpono i nā kūlana oxidizing.
ShanghaiWangYuanHe mea hana akamai i ke kaomi, pae, wela a me ke kahe ana o na mea hana no na makahiki he 20. Hiki i kā mākou ʻenehana loea ke hōʻike i ka hopena maikaʻi loa no nā pilikia o nā ʻano corrosive āpau. E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou e ʻike i nā ana kikoʻī no nā noi kaʻina hana.
