Ibikoresho byihariye bya NBR/EPDM/FKM/SIL Rubber O-Ring

NBR

Nitrile Rubber itegurwa hakoreshejwe copolymerization ya acrylonitrile na butadiene. Ingano ya acrylonitrile iri hagati ya 18% na 50%. Uko acrylonitrile ingana, ni ko irushaho kuba nziza mu kurwanya peteroli ya hydrocarbon, ariko imikorere y'ubushyuhe buri hasi iba mibi, ubushyuhe rusange bukoreshwa ni -40 ~ 120 ℃. Butanol ni imwe mu mipira ikoreshwa cyane mu gufunga amavuta no mu miringa ya O.

Ibyiza:

· Ubudahangarwa bwiza ku mavuta, amazi, amavuta ashongesha n'umuvuduko mwinshi w'amazi.

· Ifite ubushobozi bwo gukanda neza, idashira kandi ikagira uburebure.

Ibibi:

· Ntibikwiriye gukoreshwa mu bintu bisukura ikirere nka ketone, ozone, nitrohydrocarbons, MEK na chloroform. · Bikoreshwa mu gukora ikigega cya lisansi, ikigega cyo gusiga amavuta n'ibice bya rubber, cyane cyane ibice bifunga, bikoreshwa mu mavuta ya peteroli, lisansi, amazi, amavuta ya silikoni, amavuta ya silikoni, amavuta ya diester, amavuta ya ethylene glycol hydraulic n'ibindi bikoresho by'amazi. Niyo rubber seal ikoreshwa cyane kandi ihendutse.

FKM

Urusenda rwa karuboni rwa Fluoro Ubwoko ubwo aribwo bwose butandukanye bitewe n'ingano ya fluorine (imiterere ya monomer) ya molekile za fluorine. Ubudahangarwa bw'ubushyuhe bwinshi ni bwiza kurusha urusenda rwa silicone, rufite ubudahangarwa bwiza bwa shimi, rurwanya amavuta menshi n'ibintu biyungurura (usibye ketone, ester), budahangarwa n'ikirere ndetse rurwanya ozone; Ubudahangarwa bw'ubukonje ni bubi, ikoreshwa muri rusange ry'ubushyuhe bwa -20 ~ 250 ℃. Formula yihariye ishobora kwihanganira ubushyuhe buke kugeza kuri -40 ℃. Ibyiza:

· Ubudahangarwa bw'ubushyuhe kuri 250 ℃

· Irwanya amavuta menshi n'ibinyabutabire, cyane cyane aside zose, alifatique, aromatic n'amavuta y'inyamaswa n'ay'imboga

Ibibi:

· Ntibyemewe ku bintu bya ketone, esters zifite uburemere buke bwa molekile n'ibivanze birimo nitrate. · Imodoka, gari ya moshi, moteri za mazutu na sisitemu za lisansi.

SIL

Umuyoboro mukuru wa silicone Rubber ukozwe muri silikoni (-si-O-Si) ifatanye. Irwanya ubushyuhe neza, irwanya ubukonje, irwanya ozone, irwanya gusaza mu kirere. Ingufu nziza zo gukingira amashanyarazi. Ingufu zo gukurura za silikoni isanzwe ni nke kandi ntizirwanya amavuta. Ibyiza:

· Ingufu zo gukurura kugeza kuri 1500PSI no kwirinda gucika kugeza kuri 88LBS nyuma yo gukoresha

· Uburimbane bwiza kandi butuma ibintu bihindagurika neza

· Ubudahangarwa bwiza ku bintu bidafite aho bibogamiye

· Ubudahangarwa bwiza cyane ku bushyuhe

· Ubudahangarwa bwiza cyane ku bukonje

· Ubudahangarwa bwiza ku isuri rya ozone na okiside

Imikorere myiza cyane yo gukingira amashanyarazi

· Ingufu nziza zo gukingira ubushyuhe no gukwirakwiza ubushyuhe

Ibibi:

· Ntibyemewe gukoreshwa mu bintu byinshi bivanze, amavuta, aside nyinshi na hydroxide ya sodiyumu yakuwemo. · Ibifunga cyangwa ibice bya rubber bikoreshwa mu nganda z'ibikoresho byo mu rugo, nk'amasafuriya y'amashanyarazi, ibyuma, ibice bya rubber mu ziko rya mikoroonde.

· Ibifunga cyangwa ibice bya rubber mu nganda z'ikoranabuhanga, nk'imfunguzo za telefoni zigendanwa, ibikoresho bifunga impanuka muri DVD, ibifunga mu miyoboro y'insinga, n'ibindi.

· Ifunga ibintu byose bihuye n'umubiri w'umuntu, nk'amacupa y'amazi, amasoko yo kunywa, n'ibindi.

Epdm

Ethylene Rubber (PPO) iva muri Ethylene na propylene ishyirwa mu muyoboro mukuru kandi ifite ubushobozi bwo kurwanya ubushyuhe, kurwanya gusaza, kurwanya ozone no kudahungabana, ariko ntishobora kongerwamo sulfur. Kugira ngo iki kibazo gikemuke, igice gito cya gatatu gifite imiyoboro ibiri cyinjizwa mu muyoboro mukuru wa EP, ushobora gukorwa wongeyeho sulfur muri EPDM. Ubushyuhe rusange ni -50~150 ℃. Irwanya cyane ibintu bisukura nk'inzoga, ketone, glycol na phosphate lipid hydraulic fluids.

Ibyiza:

· Ubudahangarwa bwiza bw'ikirere no kurwanya ozone

· Ubudahangarwa bwiza bw'amazi n'ubudahangarwa bw'imiti

· Alcool na ketones birashobora gukoreshwa

· Ubudahangarwa n'umwuka ushyushye cyane, ubushobozi bwo kunyura muri gaze neza

Ibibi:

· Ntibyemewe ku biryo cyangwa guhura na hydrogen ihumura neza. · Ifunga ahantu hashyushye cyane hahumeka amazi.

· Ibifunga cyangwa ibice by'ibikoresho byo mu bwiherero.

· Ibice bya rubber muri sisitemu yo gufunga feri (gufunga feri).

· Gufunga mu byuma bitanga amazi (ibigega by'amazi by'imodoka).
