I ke ana ʻana o ke kaʻina hana, ʻo kekahi o nā pane nui i ka mea ana ʻinoʻino ka hoʻohana ʻana i nā mea kūpono e kū i ka ʻinoʻino no ka ʻāpana pulu o ka mea hana, ka diaphragm sensing a i ʻole kona uhi ʻana, ka hihia uila a i ʻole nā ʻāpana a me nā mea pono ʻē aʻe e pono ai.
PTFE:
ʻO ka PTFE (Polytetrafluoroethylene) kekahi ʻano palupalu, māmā a haʻahaʻa ka friction o ka plastic ʻenekinia nona ke kūpaʻa maikaʻi loa i ka palaho kemika. He hopena kūpono ia no ke kūlana koʻikoʻi i ka hana kemika a me nā ʻoihana aila a me ke kinoea. Eia nō naʻe, pono e hoʻomaopopo ʻia ʻaʻole pili ka PTFE i ka mahana hana koʻikoʻi ma luna o 260 ℃, ʻo ka paʻakikī haʻahaʻa e hana ia ʻaʻole kūpono hoʻi e lilo i mea kaula a i ʻole diaphragm.
Tantalum:
He metala kūpaʻa loa ʻo Tantalum i hiki ke kū i nā kemika huhū like ʻole, e lilo ia i koho maikaʻi loa no ka ʻike ʻana i ka mea diaphragm no nā media corrosive loa. Eia nō naʻe, he pipiʻi loa ke metala a ʻaʻole i hoʻohana pinepine ʻia e like me nā mea ʻē aʻe. I loko o kahi ʻōnaehana hana kemika e mālama ana i nā waikawa huhū loa, ua kūpono loa kahi sensor kaomi i lako me ka diaphragm ʻike tantalum no ke kūlana e hoʻokō ai i ke kiʻekiʻe kiʻekiʻe o ke kūpaʻa ʻana i ka corrosion.
Keramika:
He mea pono ʻole ka keramika i ka metala ʻole e hōʻike ana i ke kūpaʻa koʻikoʻi i ka mahana kiʻekiʻe a me ka pala. Hoʻohana pinepine ʻia nā mea ʻike Piezoresistive/capacitance me ka zirconia a i ʻole ka membrane keramika alumina i nā ʻāpana kemika, lāʻau lapaʻau, a me ka meaʻai a me ka mea inu. He mea nui hoʻi e hoʻomaopopo he palupalu ka keramika no laila ʻaʻole kūpono nā mea ʻike keramika no ka hopena kiʻekiʻe, ka haʻalulu wela a me ke kaomi a pono e mālama pono i ka wā e lawelawe ai.
ʻO Hastelloy Alloy:
ʻO Hastelloy kahi moʻo o nā mea hoʻohuihui nickel, kahi e hōʻike ai ʻo C-276 i ke kūpaʻa kūpono i ka pala a ua koho pinepine ʻia ʻo ia he mea no ka diaphragm mea kani a me nā ʻāpana pulu ʻē aʻe e kūʻē i nā mea corrosive. Hoʻohana ʻia ka mea hoʻohuihui C-276 i ka hapa nui o nā wahi ʻoihana kahi i hōʻike ʻia ai nā kūlana kemika hoʻouka kaua a hiki i nā mea ʻē aʻe ke hāʻule.
Kila kila 316L:
ʻO ke ʻano kila kila maʻamau i hoʻohana ʻia no ka diaphragm sensing ʻo ia ka papa 316L. Loaʻa iā SS316L ke kūpaʻa kūpono i ka pala, nā waiwai mechanical maikaʻi a me ke kumukūʻai kūpono. Hiki i ka pūpū kila kila o ka hale i pulu ʻole ke hoʻomaikaʻi i ka pale ʻana i ke kaiapuni ʻino. Akā ua kaupalena ʻia kona kūpaʻa ʻana i ka pala loa a emi iho me ka mahana kiʻekiʻe a me ka nui o ka corrosive medium. I kēlā hihia, pono e noʻonoʻo ʻia e hoʻololi i ke kila kila ma ka ʻāpana pulu a me ka diaphragm me nā mea ʻē aʻe maikaʻi.
ʻO Monel:
ʻO kekahi mea hoʻohuihui nickel ʻē aʻe i kapa ʻia ʻo monel. ʻOi aku ka ikaika o ka metala ma mua o ka nickel maʻemaʻe a anti-corrosive i nā ʻano waikawa like ʻole a me ka wai paʻakai. Ma nā hoʻohana kai a me ke kai, ʻo ka monel series alloy he koho kaulana ia no ka mea diaphragm. Eia nō naʻe, he pipiʻi loa ka mea a i kekahi manawa kūpono wale nō ke hiki ʻole ke koho ʻia nā koho haʻahaʻa haʻahaʻa a ʻaʻole kūpono ia i nā kūlana oxidizing.
ShanghaiWangYuanhe mea hana akamai i nā mea ana o ke kaomi, ka pae, ka mahana a me ke kahe no nā makahiki he 20 a ʻoi. Hiki i kā mākou mau ʻenekinia akamai ke hōʻike i kahi hopena kūpono no nā pilikia o nā ʻano kūlana ʻino āpau. E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou e ʻike i nā ana kikoʻī no nā noi hana kikoʻī.
