Anti-holoholona a me ka aila mea kanu ponoNeoprene (CR) Butterfly Valve Noho
Neoprene (CR)
Hoʻokumu ʻia ka Neoprene, Polychloroprene me ka polymerization monomer chloroprene. Ma hope o ka vulcanization, loaʻa iā ia ka elasticity rubber maikaʻi a me ke kūpaʻa abrasion. He anti-insolation a he maikaʻi ke kū'ē i ka wā, kū'ē i ka distortion ikaika, refrigerants, dilute acid, silicon ester lubricant, akā ʻaʻole kū i ka phosphate series o ka aila hydraulic. He maʻalahi ke crystallize a paʻakikī i ka haʻahaʻa haʻahaʻa, nāwaliwali ka mālama ʻana i ke kūpaʻa, a me ka hoʻonui nui ʻana i ka wahi aniline haʻahaʻa o ka aila mineral. I ka hoʻohana ʻana i ka pae wela he - 50 ~ 150 degere.
Pono:
ʻO ka elasticity maikaʻi a me ka deformation compression maikaʻi, ʻaʻohe sulfur i loko o ke kumu, no laila maʻalahi loa ka hana. Loaʻa iā ia nā waiwai anti - holoholona a me ka aila meaʻai, ʻaʻole e hoʻopilikia ʻia e nā kemika kūʻokoʻa, nā momona, nā ʻaila, nā ʻano ʻaila like ʻole, nā mea hoʻoheheʻe, a me nā waiwai anti-fire.
Nā hemahema:
Mai ʻōlelo ʻia e hoʻohana i nā waikawa ikaika, nitrohydrocarbons, esters, chloroform a me nā kinikona ketone.
Noi:
Nā ʻāpana Rubber a i ʻole nā ʻāpana sila me ka R12 refrigerant, nā mea pono hale. He kūpono no nā huahana lāʻau lapaʻau e pili pono ana i ka lewa, ka lā, nā ʻāpana ozone, pale i ke ahi a me ka corrosion kemika.

ʻO kā mākou pono:
1. Hoʻopaʻa paʻa ʻia ka Rubber a me nā mea hana.
2. ʻOi aku ka maikaʻi o ka lāʻau lapaʻau elasticity a me ka hoʻonohonoho ʻana.
3. ʻO ka nui o ka noho paʻa a me ka torque liʻiliʻi, ka hoʻopaʻa maikaʻi ʻana a me ka waiwai kūʻē.
4. Hoʻohana nā mea Rubber i nā hōʻailona honua me ka hana paʻa.
5. Mea waiwai: CR, NR, SBR, NBR, EPDM, PTFE, Silicone, etc.
6. Hōʻoia: NSF, SGS, KTW, FDA, ISO9001, ROHS,
7. Kiʻekiʻe / haʻahaʻa wela kū'ē, aila a me ka wahie kū'ē, maikai ea tightness etc.
8. ʻO ke kaʻina hana a me ka hoʻopili ʻana e like me kāu mau koi.
9. Noi: Ka hoʻomalu wai, ka uila, nā mea hana hale, nā kaʻa, nā ʻoihana lāʻau lapaʻau, nā mīkini ʻenehana a me nā ʻāpana, etc.
Mea pili i ka papa koho wikiwiki:
| Mea waiwai | Temp kūpono. | Nā hiʻohiʻona |
| NBR |
-35 ℃~100 ℃ Hikiwawe -40 ℃~125 ℃ |
Loaʻa i ka ʻōpala Nitrile maikaʻi iā ia iho-e hoʻonui i nā waiwai, kū i ka abrasion a me nā waiwai hydrocarbon-kūpono. Hiki ke hoʻohanaʻia ma keʻano he mea maʻamau no ka wai, vacuum, acid, salt, alkali, grease, oil, butter, hydraulic oil, glycol, etc. ʻAʻole hiki ke hoʻohanaʻia ma nā wahi e like me ka acetone, ketone, nitrate, a me nā hydrocarbons fluorinated. |
| EPDM |
-40 ℃~135 ℃ Hikiwawe -50℃~150℃ |
ʻO ka ethylene-propylene rubber he lāʻau synthetic maikaʻi e hiki ke hoʻohana ʻia i nā ʻōnaehana wai wela, nā mea inu, nā huahana waiu, nā ketones, nā waiʻona, nā nitrates, a me ka glycerin, akā ʻaʻole i loko o nā aila hydrocarbon-

-35 ℃~100 ℃ Hikiwawe -40 ℃~125 ℃ |
Hoʻohana ʻia ʻo Neoprene i ka media e like me nā waikawa, nā aila, nā momona, nā pata a me nā solvents a maikaʻi ke kūʻē i ka hoʻouka ʻana. |
| FKM |
-20 ℃~180 ℃

ʻO ka Fluororubber kahi ʻaila hydrocarbon maikaʻi-kūpaʻa kumu, ʻo ka pulupulu hydrocarbon fluorinated no ke kinoea ʻaila a me nā huahana aila ʻē aʻe. He kūpono ia no ka wai, ka aila, ka ea, ka waikawa a me nā mea ʻē aʻe, akā ʻaʻole hiki ke hoʻohana ʻia no ka mahu, ka wai wela a i ʻole ka mānoanoa ma mua o 82 °C. Pūnaehana alkali. |
| SR | -70 ℃~200 ℃ | Paʻa ka silicone rubber i ke kiʻekiʻe wela, haʻahaʻa haʻahaʻa a me nā waiwai kemika paʻa, a hoʻohana nui ʻia i nā ʻoihana e like me ka waikawa ikaika, ka alkali palupalu a me ka meaʻai. |
Mea kūikawā: ka pahu nitrile carboxylated, hydrogenated nitrile rubber, corrosion-ethylene kūpaʻa-propylene rubber, mahu-fluoroelastomer kūpaʻa, chlorosulfonated polyethylene |

Hana ʻia mai nā mea waiwai, ʻo ka hui pū ʻana o PTFE a me EPDM i loko o kā mākou mau noho valve hāʻawi i ke kūpaʻa kūʻokoʻa ʻole i ka ʻaʻahu a me ka waimaka, e kūpono ana ia no ka hoʻohana ʻana i nā kaiapuni me nā mahana ma waena o -50 a 150 degere Celsius. ʻAʻole kēia hui ʻokoʻa e hōʻoiaʻiʻo i ka lōʻihi-manawa resilience akā hāʻawi pū kekahi i nā mea hoʻopaʻa sila maikaʻi, hoʻonui i ka pono holoʻokoʻa o kāu ʻōnaehana. He kūpono no ka lawelawe ʻana i nā media like ʻole me ka wai, ka wai inu, ka wai inu, a me ka wai ʻino, ua hoʻolālā ʻia kā mākou mau noho valve e hoʻokō i nā koi koʻikoʻi o nā noi ʻoihana like ʻole. hoʻokomo i nā misalignments liʻiliʻi i ka paipu, e hōʻoia i ka sila paʻa a me ka liʻiliʻi liʻiliʻi. ʻAʻole kēia huahana he mea hoʻohui wale i kāu ʻōnaehana; He hoʻomaikaʻi koʻikoʻi ia e hoʻohiki ai e hoʻokō pono i ka hana, e hōʻemi i nā kumukūʻai mālama, a hoʻonui i ke ola o kāu mau kiwi lele. Inā ʻoe i loko o ka ʻoihana mālama wai, hana meaʻai a mea inu, a i ʻole ka hana kemika, ʻo ka Keystone Butterfly Valve Figure 990 me kāna PTFE + EPDM butterfly valve seat hiki ke hoʻololi ʻia kāu hele - i ka hopena no ka hilinaʻi a me ka maikaʻi o ka hana valve.
