PTFE gaskets, Ma muli o kona palupalu, nui compression ratio, maʻalahi e hana i loko o ʻekolu-dimensional space, hiki ke hoʻokomo ʻia i loko o nā micro māwae a me nā pōʻino e hoʻoponopono a hoʻopaʻa i nā leaks, ʻoi aku hoʻi i ka pilina o ka waika, alkali, corrosion a me nā mea hao ʻole, nui. - nā moku anawaena He mea koʻikoʻi ka hopena, a hiki iā ia ke pale pono i ka pilina o nā mea brittle.
No nā mea metala ʻole e like me ke aniani, nā ceramics, graphite, plastics, etc., he hopena kupaianaha.Hiki iā ia ke hoʻopaʻi a hoʻopaʻa i nā hewa i hoʻokumu ʻia e nā hemahema, ka hana mechanical, rigid deformation, hoʻonohonoho misalignment, a me nā mea ʻē aʻe.
ʻO nā ʻano o ka PTFE gaskets
1. Pure PTFE gasket
ʻO nā gaskets PTFE maʻemaʻe he mau pahu paʻa, V-like gaskets, piston apo, ball valve gaskets, etc., i huli ʻia a ʻoki ʻia paha mai ka mīkini.kookoo PTFE, PTFE paipu, aPepa PTFE, ʻo ia ka corrosion-resistant, anti-aging, a me ka non-conductive.ʻO nā hiʻohiʻona maikaʻi.Hiki iā ia ke loaʻa ka ikaika mechanical maikaʻi ma waena o -100 ° C a me 100 ° C.
ʻO kekahi hiʻohiʻona o kēia huahana he maʻemaʻe.No kekahi mau mea hiki ke komo i loko o ka pilina me ia, ʻaʻole e hoʻohaumia nā gaskets PTFE maʻemaʻe iā lākou.Hoʻohana nui ʻia kēia pono i ka meaʻai a me ka lāʻau lapaʻau.
2. Hoʻololi PTFE gasket
Keia 'ano o ka PTFE gasket komo elua waeʻano, graphite piha a me ke aniani fiber-piha.
ʻO ka gasket tetrafluoroethylene piha i ka Graphite he PTFE me ka graphite e like me ka hoʻopiha piha no ka hui pū ʻana a me ke ahi wela kiʻekiʻe.ʻO kēia gasket PTFE he hoʻopaʻa maikaʻi loa a me ka compressibility.
Hoʻohana nā kīʻaha PTFE i hoʻopiha ʻia i ke aniani fiber i mea hoʻopiha.Loaʻa i kēia mea waiwai nā waiwai hoʻihoʻi maikaʻi a ʻoi aku ka maikaʻi ma mua o nā mea kahiko i ka hana.ʻAʻole ʻaʻahu a kūpaʻa kemika a kūpono loa i nā ʻoihana pepa a me nā meaʻai.
3. Hoʻonui PTFE Gasket
Hiki i nā gaskets PTFE hoʻonui ke pale i ke kahe anuanu a me ka kolo, a loaʻa iā ia ka pōmaikaʻi o ka maʻalahi o ka hoʻouka ʻana, ʻoi aku ka hiki ke kū i nā wela haʻahaʻa haʻahaʻa.ʻO ka hana hoʻopaʻa ʻana o kēia mea he mea hilinaʻi loa, a he kūpaʻa nō hoʻi ia i ka pohā.He kūpono loa ia no nā ʻili ʻōpala.
8 pono o ka PTFE gasket
1. ʻO ka PTFE gasket pono'ī he kiʻekiʻe ka corrosion kū'ē, kūpaʻa kino hana, kiʻekiʻe a me ka haʻahaʻa-mahana kū'ē, a hoʻokō i kona maikaʻi sealing hana.Ma ka hoʻololiʻana i ka ikaika o ke kāʻei hao i hoʻopaʻaʻia, hiki ke hoʻololiʻia ka nui (paʻakikī) o ka gasket i hoʻopiliʻia e kūpono i nā pono o nā noi likeʻole.Hoʻohana nui ʻia ia i ka petrochemical, mīkini, mana uila, metallurgy, hana moku, lāʻau lapaʻau, atomic ikehu, a me nā ʻoihana aerospace.
2. PTFE gaskets he aniau-kue, a me ka PTFE i ka maikai elemakule ola ma waena o plastics.ʻO ka PTFE gasket pono'ī he kiʻekiʻe ka corrosion kū'ē, kūpaʻa kino hana, kiʻekiʻe a me ka haʻahaʻa-mahana kū'ē, a ua hoʻokō maikaʻi hana sila.Hoʻohana nui ʻia ia i ka petroleum, chemical, pharmaceutical, electric power, a me nā ʻoihana kila.
3. ʻAʻole pili ka PTFE gasket.ʻO ka PTFE ka liʻiliʻi liʻiliʻi ma waena o nā mea paʻa a ʻaʻole pili i kekahi mea.
4. ʻO nā gaskets PTFE ke kū'ē i nā haʻahaʻa haʻahaʻa a loaʻa ka ikaika mechanical maikaʻi;ʻoiai inā hāʻule ka mahana i -196 ° C, hiki iā lākou ke mālama i ka 5% elongation.He kūpono ia no ka hoʻopaʻa ʻana i nā ʻāpana kahi e loli nui ai ka mahana a me ke kaomi.He mea hoʻopaʻa hoʻopaʻa paʻa ia no nā pili flange e like me nā paipu, nā valves, nā pamu, nā mea hoʻololi wela, nā hale kiaʻi, nā manholes, a me nā lua lima.
5. ʻO nā hana a me nā pono o nā gaskets PTFE penei.ʻO ke ala kūpono e pili ana i nā mea kemika a pau e like me ka wai, ka aila, ka hopena waika, ka hopena alkali, etc.
6. PTFE gasket mea ole a me ka PTFE i physiologically inert, a me ka mea, aole adverse reactions like artificial koko a me na kino i hookomoia i loko o ke kino no ka manawa lōʻihi.
7. ʻO nā gaskets PTFE he kūpaʻa i ka corrosion, he inert i ka hapa nui o nā kemika a me nā mea hoʻoheheʻe, a hiki ke kū i nā waikawa ikaika a me nā alkalis, ka wai a me nā mea hoʻoheheʻe kūlohelohe.Loaʻa i kēia gasket ka hoʻokō maikaʻi ʻana a me ka hana resilience, ka hoʻopaʻa ʻana i nā kaila he nui, a me kekahi hana hoʻopaʻa ponoʻī, hiki ke hoʻopau i ka mana o ke kaomi, hoʻololi ʻana i ka mahana, a me ka haʻalulu mechanical.
8. Ma lalo o ke kiʻekiʻe wela, haʻahaʻa wela, kiʻekiʻe vacuum, haʻalulu haʻalulu, a me nā hoʻololi cyclical ʻē aʻe a me nā kūlana koʻikoʻi like ʻole, e mālama i kāna hana sila maikaʻi loa.Ma ka hoʻololi ʻana i ka hui pū ʻana o ka gasket, hiki ke hoʻonā ʻia ka pilikia o ka hoʻoheheʻe ʻana o ke kinona o ka gasket e nā media like ʻole.ʻAʻole i hoʻopaʻa ʻia ka ʻili flange, e maʻalahi i ka mālama ʻana a me ka hoʻololi ʻana.
9. Hiki ke hoʻohana ʻia nā gaskets PTFE i nā wela kiʻekiʻe, a hiki ke hoʻohana ʻia ka PTFE ma kahi mahana hana o 250 ° C.
He aha nā mea e noʻonoʻo ai i ke koho ʻana i nā gaskets PTFE
Hoʻohana ʻia nā gaskets PTFE i nā ʻano mea hana.I mea e hōʻoiaʻiʻo ai i ka hana maikaʻi, nā kumu e noʻonoʻo ʻia i ke koho ʻana i nā gaskets PTFE penei:
1. Medium: He maʻalahi ka nīnau o ka mea waena.Pono wale e hoʻolohe i kekahi mau nīnau liʻiliʻi kūikawā, e like me ka metallurgical work cylinders e hoʻohana pinepine i ka wai-glycol a me ka phosphate ester hydraulic aila.
2. Ka Mahana: Pono e noʻonoʻo ʻia ka NBR kūʻokoʻa i ke anuanu ke 20 ~ -40 ℃ ka mahana.ʻO ka mea nui NBR e paʻakikī i ka mea ma lalo o ke kaiapuni haʻahaʻa haʻahaʻa, e hopena i ka leakage.
3. Paʻi hopena: Ke hoʻomaka a pani ʻia ka mīkini hana, ʻoi aku ka nui o kona hopena ma mua o ke kaomi hana maʻamau, no laila e hoʻohana pinepine ʻia ʻo ia ka sila nui me ka hopena hopena a me ka ʻoki ʻana i ka HBY a i ʻole SPGW me ka paʻi paʻi o a hiki i 70MPA.
