Hoʻopili ʻia ʻo Rubber Butterfly Valve, i loko me ka ebonite lining o ka mānoanoa 3mm a i ʻole 5mm, hoʻohana nui ʻia i loko o ka wai hoʻoheheʻe, ʻoihana kemika, mālama wai kai a me ka papahana desalinization etc.
Kūlana hoʻolālā: BS EN593, AWWA C504, API 609
He alo a he alo ka lōʻihi: EN558-1/ISO5752 series 14 a i ʻole Series 13, AWWA C504
Nui: DN300 – DN3600/12″-144″
Ka helu kaomi: PN6- PN10-PN16-PN25-PN40/75psi-150psi-250psi-350psi-580psi
ʻO nā kiwi lele lele i hoʻopaʻa ʻia a pau i ka hilinaʻi kiʻekiʻe, ka hoʻolālā ikaika e like me nā kūlana ambient maikaʻi loa.
Laina Ebonite: loaʻa ke kūpaʻa kemika maikaʻi, ke kūpaʻa kino kino maikaʻi a me ke kūpaʻa ʻana o ka mea hoʻoheheʻe, haʻahaʻa wai absorption, kiʻekiʻe tensile ikaika a me ka maikaʻi o ka uila insulation etc.features.
Hoʻokumu ka lining ebonite i kahi papa uhi mau ma luna o ka substrate e hoʻohui i ka hoʻolālā kūikawā a me ke kaʻina hana o ka hui e hoʻokaʻawale loa i ka substrate ferrous mai ke kikowaena lawelawe, no laila e hōʻoia i ka manawa lawelawe lōʻihi o ka huahana.
No ka wai lawelawe corrosive, ʻoi aku ka maikaʻi o ke kumu kūʻai.
ʻO ka wahi e pale ʻia e ka lining ebonite e hoʻoheheʻe ʻia i ke one e hōʻike i ka metala keʻokeʻo a hiki i ka maʻemaʻe Sa 2.5 a i ISO 8501 a me ke ʻano ʻeleʻele G i ISO 8503.
Ma lalo o ke kaiapuni me ka haʻahaʻa ʻaʻole iʻoi aku ma mua o 60% a me ka mahana o 15-40 ℃, e hoʻohana i nā mea hana lining e pono ai e like me ka roller pressure a me ka scraper e hoʻopaʻa piha i ka ʻōpala a me ka substrate e like me nā kaʻina hana koʻikoʻi a me nā koi.
Hana ʻia ka vulcanization lining ebonite me ka ea wela a i ʻole ka mahu i loko o ka ipu vulcanization.
Hiki ke hoʻomaka wale ʻia ke kaʻina hana ma hope o ka hala ʻana i nā hoʻokolohua like ʻole a me ka nānā ʻana (nānā hiʻohiʻona, ʻike ʻia ka uila uila i nā lā hoʻomaha/pinholes/cracks, adhesion test and hardness test etc.)
ʻO ka laulā paʻakikī e loaʻa iā Shore D 75±5.
Ka pale ʻino o waho:Hāʻawi ʻia kēia ʻōnaehana pena e kūpono i ka noi o ka māhele corrosivity C5 e like me EN ISO 12944-2,
Epoxy zinc-rich primer - 60μm, Epoxy micaceous iron/pena waena - 120μm, Acrylic polyurethane hoʻopau pena - 60μm, Huina piha maloʻo mānoanoa (DFT) 240μm
Epoxy aniani flake primer- 80μm, Epoxy aniani flake pena ʻelua papa - 160μm, ʻO ka mānoanoa maloʻo piha piha (DFT) 240μm
ʻO nā mea hoʻopaʻa āpau i loko a me waho e like me nā nati, nā bolts, nā wili a me nā mea hoʻopili e hana ʻia me ke kila kila kila kila 316L a i ʻole ke kila kila kila.
ʻO nā kiwi lele lele i hoʻopaʻa ʻia a pau i kūpono ke hoʻopaʻa ʻia ma ke kūlana kūpaʻa a i ʻole ke kūlana ākea.
Hoʻopaʻa ʻia ka maka hoʻokiʻekiʻe/hoʻokiʻekiʻe i ke kūlana kūpono i hiki ke hoʻokiʻekiʻe ʻia ka valve ma ke kūlana kūpaʻa a i ʻole.
