Wela welding Socket PVDF True Union Ball Valve me FPM O-rings PTEF Noho
He aha ka PVDF valve?
ʻO ka valve PVDF kahi ʻano valve i hana ʻia me ka polyvinylidene fluoride (PVDF). ʻO PVDF kahi ʻano mea polymer me ke kūpaʻa kemika maikaʻi loa, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana o ka oxidation, ka pale ultraviolet a me ke kūpaʻa abrasion, a me nā mea ʻē aʻe. Ma ke kahua o nā valves, hoʻohana mau ʻia nā valves PVDF no ka mālama ʻana i ke ʻano corrosive, medium wela kiʻekiʻe a me ka medium-containing medium.
He aha nā hiʻohiʻona o ka valve material PVDF?
ʻO PVDF kahi ʻano fluoroplastic me ke kūpaʻa kemika maikaʻi loa, ka pale ʻana i ka wā, ka pale abrasion a me ke kūpaʻa ʻelemakule, hiki ke mālama i ka hana maikaʻi ma kahi ākea ākea. ʻO ka mea kikoʻī, loaʻa nā mea PVDF i kēia mau hiʻohiʻona.
Paʻa kemika:
Loaʻa i nā mea PVDF ke kūpaʻa kemika maikaʻi loa a hiki ke kūʻē i ka nui o nā media corrosive e like me nā waikawa, nā alkali, nā paʻakai a me nā mea hoʻoheheʻe organik.
Loaʻa nā ʻano o ka mea
Kūleʻa wela kiʻekiʻe:
ʻO ka helu heheʻe o ka mea PVDF ma kahi o 170 ℃, hiki ke mālama i ka hana maikaʻi ma lalo o ke kiʻekiʻe kiʻekiʻe.
Ke kū'ē i ka oxidation:
ʻAʻole maʻalahi ka mea PVDF i ka oxidize i ke kiʻekiʻe wela, a hiki ke mālama i kāna mau waiwai mechanical no ka manawa lōʻihi.
Kū'ē abrasion:
ʻOi aku ka maikaʻi o ka pale ʻana o ka mea PVDF ma mua o ka hapa nui o nā plastic engineering, hiki ke mālama i kona ʻili i ka maʻalahi no ka manawa lōʻihi.
Kūʻē ʻelemakule:
ʻAʻole maʻalahi nā mea PVDF i ka makahiki ma lalo o ka radiation ultraviolet, a hiki ke mālama i kona mau waiwai kino no ka manawa lōʻihi.
He aha nā mea maikaʻi o ka valve PVDF?
No ka loaʻa ʻana o nā mea pono o ka PVDF, no laila ua loaʻa i ka valve PVDF nā pono aʻe.
ʻO ke kūpaʻa ʻino:
Hiki i nā kiwi PVDF ke pale aku i ka hapa nui o nā waikawa, nā alkalis, nā paʻakai a me nā mea hoʻoheheʻe organik a me nā mea ʻino ʻē aʻe, kūpono no nā ʻano lapaʻau media Corrosive.
Hana wela kiʻekiʻe:
Hiki i nā valve PVDF ke mālama i ka hana maikaʻi ma nā wela kiʻekiʻe, kūpono no ka hoʻoili ʻana i ka media kiʻekiʻe.
kū'ē abrasion:
ʻOi aku ka maikaʻi o ka pale ʻana o nā valve PVDF ma mua o ka hapa nui o nā plastics engineering, hiki iā ʻoe ke mālama i kona ʻili ma kahi lōʻihi, ʻaʻole maʻalahi.
Ke kū'ē i ka wā kahiko:
ʻAʻole maʻalahi nā PVDF valves i ka radiation ultraviolet i ka ʻelemakule, hiki ke mālama i kona mau kino kino no ka manawa lōʻihi.
Ka maʻemaʻe a me ka maʻemaʻe:
He maʻalahi ka hoʻomaʻemaʻe PVDF valves, hiki ke hoʻohana ʻia i ka meaʻai, ka lāʻau lapaʻau a me nā wahi ʻē aʻe o nā koi maʻemaʻe kiʻekiʻe.
Ke ola lōʻihi:
No ka mea he waiwai waiwai maikaʻi loa nā valves PVDF a me ke kaʻina hana hana, kona ola lōʻihi, hiki iā ʻoe ke mālama i ke kumukūʻai o ka hoʻololi ʻana i ka valve a me ka manawa.
