Ibikoresho byabigenewe NBR / EPDM / FKM / SIL Rubber O-Impeta

NBR

Nitrile Rubber itegurwa na copolymerisation ya acrylonitrile na butadiene.Ibiri muri acrylonitrile biri hagati ya 18% na 50%.Iyo hejuru ya acrylonitrile, niko arwanya amavuta ya hydrocarubone, ariko ubushyuhe buke bukaba bubi, muri rusange ikoreshwa ryubushyuhe ni -40 ~ 120 ℃.Butanol ni imwe mu rebero ikoreshwa cyane kuri kashe ya peteroli na O-impeta.

Ibyiza:

· Kurwanya neza amavuta, amazi, ibishishwa hamwe namavuta yumuvuduko mwinshi.

· Guhindura neza kwikuramo, kwambara birwanya no kuramba.

Ibibi:

· Ntibikwiye kumashanyarazi ya polar nka ketone, ozone, hydrocarbone ya nitro, MEK na chloroform.· Ikoreshwa mugukora ikigega cya lisansi, gusiga amavuta hamwe nibice bya reberi, cyane cyane ibice bifunga kashe, bikoreshwa mumavuta ya hydraulic ya peteroli, lisansi, amazi, amavuta ya silicon, amavuta ya silicon, amavuta yo kwisiga amavuta, amavuta ya hydroulic etylene glycol nibindi bitangazamakuru byamazi.Nibikoreshwa cyane kandi bihenze cyane bya kashe ya rubber.

FKM

Fluoro Carbon Rubber Ubwoko ubwo aribwo bwose butandukanye bitewe na fluor (imiterere ya monomer) ya molekile ya fluor.Kurwanya ubushyuhe bwinshi biruta reberi ya silicone, ifite imiti irwanya imiti, irwanya amavuta menshi hamwe na solvent (usibye ketone, ester), kurwanya ikirere no kurwanya ozone;Kurwanya ubukonje ni bibi, ikoreshwa rusange ryubushyuhe bwa -20 ~ 250 ℃.Inzira idasanzwe irashobora kwihanganira ubushyuhe buke kugeza kuri -40 ℃.Ibyiza:

· Kurwanya ubushyuhe kuri 250 ℃

· Kurwanya amavuta menshi hamwe nuwashonga, cyane cyane acide zose, alifatique, impumuro nziza ninyamaswa nimboga.

Ibibi:

· Ntabwo bisabwa kuri ketone, esters yuburemere buke bwa molekile hamwe nuruvange rurimo nitrate.· Imodoka, moteri, moteri ya mazutu na sisitemu ya lisansi.

SIL

Silicone Rubber urunigi nyamukuru rukozwe muri silicon (-si-O-Si) ihujwe hamwe.Kurwanya ubushyuhe buhebuje, kurwanya ubukonje, kurwanya ozone, kurwanya gusaza kwikirere.Imikorere myiza yo gukwirakwiza amashanyarazi.Imbaraga zingana za reberi isanzwe irakennye kandi ntabwo irwanya amavuta.Ibyiza:

· Imbaraga zingana kugeza 1500PSI no kurira amarira kugeza 88LBS nyuma yo kuyikora

· Elastique nziza no kugoreka neza

· Kurwanya neza kumashanyarazi adafite aho abogamiye

· Kurwanya ubushyuhe buhebuje

· Kurwanya ubukonje buhebuje

· Kurwanya bihebuje kurwanya ozone na okiside

Imikorere myiza yamashanyarazi

· Gukwirakwiza ubushyuhe buhebuje no gukwirakwiza ubushyuhe

Ibibi:

· Ntabwo byemewe gukoreshwa mumashanyarazi menshi, amavuta, acide yibanze hamwe na hydroxide ya sodium.· Ikidodo cyangwa reberi ikoreshwa mu nganda zikoreshwa mu rugo, nka POTS y’amashanyarazi, ibyuma, ibice bya reberi mu ziko rya microwave.

· Ikidodo cyangwa ibice bya reberi mu nganda za elegitoroniki, nk'urufunguzo rwa terefone igendanwa, ibyuma bikurura amashanyarazi muri DVD, kashe mu nsinga, n'ibindi.

· Ikidodo ku bintu byose bihura numubiri wumuntu, nkamacupa yamazi, amasoko yo kunywa, nibindi.

Epdm

Ethylene Rubber (PPO) ikoporora muri Ethylene na propylene mumurongo wingenzi kandi ifite ubushyuhe buhebuje, kurwanya gusaza, kurwanya ozone no guhagarara neza, ariko ntibishobora kongerwamo sulfure.Kugira ngo iki kibazo gikemuke, umubare muto wibice bya gatatu hamwe nuruhererekane rwinjizwa mumurongo nyamukuru wa EP, ushobora gushingwa wongeyeho sulfure muri EPDM.Ubushyuhe rusange ni -50 ~ 150 ℃.Kurwanya cyane imishwarara ya polar nka alcool, ketone, glycol na fosifate lipid hydraulic fluid.

Ibyiza:

· Kurwanya ikirere cyiza no kurwanya ozone

· Kurwanya amazi meza no kurwanya imiti

· Inzoga na ketone birashobora gukoreshwa

· Ubushyuhe bwo hejuru bwo guhangana nubushyuhe, kutoroherwa na gaze

Ibibi:

· Ntabwo bisabwa gukoresha ibiryo cyangwa guhura na hydrogen nziza.· Ikidodo cyubushyuhe bwo hejuru bwamazi.

· Ikidodo cyangwa ibice by ibikoresho byo mu bwiherero.

· Ibice bya reberi muri sisitemu yo gufata feri (feri).

· Ikidodo mumashanyarazi (ibigega byamazi yimodoka).
