Hoʻohana nui ʻia ka valve ball plastic no ka ʻoki ʻana a i ʻole ka hoʻopili ʻana i ke kikowaena i loko o ka pipeline, akā hoʻohana pū ʻia no ka hoʻoponopono a me ka mālama ʻana i nā wai.He nui nā pōmaikaʻi o ka ball valve, e like me ka haʻahaʻa haʻahaʻa o ka wai, ke kaumaha māmā, ka paʻa a me ka nani o ke ʻano, ka pale ʻana i ka corrosion, ka laulā o nā noi, nā mea maʻemaʻe a me nā mea ʻawaʻawa ʻole, nā lole pale, maʻalahi ka wehe ʻana, mālama maʻalahi.No ke aha i loaʻa ai nā pono he nui?ʻO kēia ka mea a mākou e ʻimi nei i kēia lā - ka mea.
He ʻokoʻa nā ʻano mea like ʻole, a i ka wā e hana ʻia ai ia i loko o kahi kiwi pōpō palaka, e hāʻawi ʻia ka valve pōpō plastik i nā ʻano o ka mea ponoʻī.I kēia lā, nui nā mea i hoʻohana ʻia no ka hana ʻana i nā kiwi pōpō plastik, e like me UPVC, RPP, PVDF, PPH, CPVC, etc.
Kapa ʻia ʻo UPVC he PVC paʻakikī, he resin thermoplastic amorphous i hana ʻia me ka vinyl chloride monomer e ka polymerization reaction me kekahi mau mea hoʻohui (e like me stabilizers, lubricants, fillers, etc.) kūpaʻa, akā loaʻa nō hoʻi ka ikaika mechanical kiʻekiʻe a hoʻokō i nā kūlana hoʻomaʻemaʻe wai inu ʻāina.ʻOi aku ka maikaʻi o ka hana hoʻopaʻa huahana, hoʻohana nui ʻia i ka hana kīwila, kemika, lāʻau lapaʻau, petrochemical, metallurgy, mahiʻai, irrigation, aquaculture a me nā ʻōnaehana alanui wai.-10 ℃ a 70 ℃ ka wela wela.
ʻO RPP kahi mea polypropylene i hoʻoikaika ʻia.ʻO nā kiwi pōleʻa i hui ʻia a hoʻoheheʻe ʻia me nā ʻāpana hoʻoheheʻe RPP he kūpaʻa maikaʻi loa i ka corrosion, hoʻolōʻihi i ke ola lawelawe, hoʻololi maʻalahi a maʻalahi ka hoʻohana.-20 ℃ a 90 ℃ ka wela wela.
ʻO Polyvinylidene fluoride, PVDF no ka pōkole, he fluoropolymer thermoplastic non-reactive.He mea pale ahi ia, pale i ka luhi a ʻaʻole maʻalahi e wāwahi, anti-wear, maikaʻi pono-lubricating waiwai, maikaʻi insulation mea.He paʻa kemika maikaʻi ʻo PVDF ball valve, kūpaʻa kemika a me ke kūpaʻa pale wela.Hiki ke hoʻohana ʻia no ka manawa lōʻihi i ka pae wela o -40 ℃ a 140 ℃, a hiki ke pale aku i ka paʻakai, ka waikawa, ka alkali, ka hydrocarbon aromatic, ka halogen a me nā media ʻē aʻe koe nā mea hoʻoheheʻe ikaika.
ʻO ka CPVC kahi ʻano hou o ka ʻenekinia plastic me ka hoʻohana hoʻohiki.ʻO ka huahana he keʻokeʻo a ʻulaʻula paha melemele ʻono ʻole, ʻaʻala ʻole, ʻaʻohe ʻawaʻawa ʻawaʻawa granules a pauda.cpvc ball valve inā i loko o ka waika, alkali, paʻakai, chlorine, oxidation environment, i ʻike ʻia i ka ea, kanu ʻia i loko o ka lepo corrosive, ʻoiai ma 95 ℃ wela kiʻekiʻe, ʻaʻole e ʻino ʻia i loko a i waho, ʻoiai ikaika a hilinaʻi hoʻi e like me ka mea mua. hoʻokomo.
