Fluoroelastomers / VITON® Rubber

Fluoroelastomers ndi copolymers m'banja la mankhwala opangira mphira, omwe, atayambitsidwa koyamba, anali ndi hexafluoropropylene ndi vinylidene. Masiku ano, kusasinthika kwa Fluoroelastomers kwasinthidwa kuti kukhale kukhazikika kwamafuta komanso kukana zosungunulira. Gulu lopangira labalali limapereka premium, kudalirika kwanthawi yayitali ngakhale m'malo ovuta kwambiri.

Ma Fluoroelastomers a King-rubber sagonjetsedwa ndi mankhwala, mafuta, ndi kutentha. Ma Fluoroelastomers athu amagwiritsidwa ntchito pazinthu zingapo zogwira ntchito kwambiri muzamlengalenga, magalimoto, mafakitale, ndi zina zambiri. Ma Fluoroelastomers amapangidwa mwachizolowezi kukhala zinthu zosiyanasiyana zamphira kuphatikiza zisindikizo, mphete za o, ma gaskets a rabara, ma valve, ndi ma diaphragms a rabara.

Viton® ndi chizindikiro cholembetsedwa cha Dupont Dow Elastomers LLC Viton® imagwiritsidwa ntchito m'gulu la zopangira mphira za fluorocarbon elastomers. Copolymer imasankhidwa pagulu la mphira la Viton® kutengera momwe amapangira. Ma polima omwe amagwiritsidwa ntchito kwambiri ndi hexafluoropropylene (HFP) ndi vinylidene fluoride (VDF kapena VF2), terpolymers of tetrafluoroethylene (TFE), vinylidene fluoride (VDF) ndi hexafluoropropylene (HFP), ndi perfluoromethylvinylether (PMVE).

Pierce-Roberts Viton® imapereka kukhazikika kwa kutentha, kutsika kwapang'onopang'ono, komanso kukana mankhwala, mafuta, ndi ozoni. Ngakhale kuti Viton® poyamba inapangidwira makampani opanga ndege; mphira uwu umagwiritsidwanso ntchito mu mphamvu zamadzimadzi, magalimoto, zida zamagetsi, ndi mankhwala opangira mphira monga ma hoses, seals, o-rings, zolumikizira zowonjezera, zisindikizo za shaft, ndi ma gaskets a rabara.

Mpira wa Urethane

Rabara ya urethane, yomwe imadziwikanso kuti spandex, ndi polima yomwe ili ndi chipika cha urethane champhamvu komanso kukana kutentha komanso chotchinga cha polyether cha elasticity. Zotsatira zake, mphira wa urethane amaonedwa kuti ndi imodzi mwazinthu zosunthika kwambiri zomwe zimapezeka. Rabara ya urethane imagonjetsedwa ndi abrasion, mphamvu zamphamvu, ozoni, mankhwala, ndi cheza.

Urethane ndi mphira wosamva mafuta ndipo imagwira ntchito bwino popaka mafuta ndi mafuta. Kukhazikika kwake kwakukulu komanso kusinthasintha kwa kutentha kumapangitsa kuti mphira wa King-rabara wapamwamba kwambiri wa urethane ugwiritsidwe ntchito kuphatikiza zodzigudubuza za mphira, malamba, ma diaphragms a rabara, mphete za o-rings, ma gaskets a mphira, zisindikizo, chubu cha payipi ndi zovundikira, zodzipatula za vibration, ma bumpers, ma impellers, ndi Zambiri.

Ma Fluoroelastomers a King-rubber sagonjetsedwa ndi mankhwala, mafuta, ndi kutentha. Ma Fluoroelastomers athu amagwiritsidwa ntchito pazinthu zingapo zogwira ntchito kwambiri muzamlengalenga, magalimoto, mafakitale, ndi zina zambiri. Ma Fluoroelastomers amapangidwa mwachizolowezi kukhala zinthu zosiyanasiyana zamphira kuphatikiza zisindikizo, mphete za o, ma gaskets a rabara, ma valve, ndi ma diaphragms a rabara.

Silicone

Rabara ya silicone ndi polymer yachilengedwe yokhala ndi silikoni ndi okosijeni. Mankhwala a mphira a silicone amatha kusinthidwa kudzera mu zowonjezera kuphatikizapo fluorine, phenyl, ndi vinyl. Fluorine imatha kukopa zinthu zomwe zili mu silikoni wamba ndipo imatha kukana zosungunulira monga mafuta. Phenyl imathandizira kusinthasintha kwa kutentha komanso kukana ma radiation a gamma. Vinyl imapangitsa kuti vulcanization ikhale yabwino komanso compression set.

Rabara ya Silicone ya King-rabara imakana ozone, malo owopsa a chilengedwe, ma radiation, chinyezi, ndi mankhwala, ndipo imatha kusunga umphumphu pambuyo pa kupsinjika. Kuonjezera apo, mankhwala ena a mphira a silikoni ndi oletsa moto. Zopangira mphira zamtundu wa sililicone zimaphatikizapo zolumikizira, ma diaphragms a rabara, ndi zoyatsira mphamvu. Moyo wautali wautumiki umapangitsa kuti mphira iyi ikhale yabwino kwa mafakitale ambiri.

Hello N Rubber

Buna N rabala ndi mphira wopangidwa ndi mphira womwe umadziwikanso kuti mphira wamba wa Nitrile. Gululi limapangidwa ndi ma co-polymers: acrylonitrile ndi butadiene. Acrylonitrile ndi madzi osungunuka a organic. Butadiene ndi mankhwala opangira mankhwala. Akasakanizidwa, ma polima awiriwa amachitapo kanthu ndikupanga mphira imodzi yamphamvu kwambiri yosamva mafuta yomwe ilipo pakali pano.

Zopangira mphira za Buna N zimagonjetsedwa ndi zosungunulira ndi mafuta. Zopangira mphira zopangidwa ndi Pierce-Roberts zomwe zimapangidwa ndi Buna N ndizoyenera kugwiritsa ntchito mafakitale ambiri, kuphatikiza mapaipi amafuta, mapaipi amafuta, ma o-rings, ndi ma gaskets a rabara. Buna N ndi yofanana ndi Buna S chifukwa imatha kusokonezedwa.
