Ni irihe tandukaniro riri hagati ya Silicone Rubber na EPDM?

Mugihe uhitamo reberi yo gukoresha, ba injeniyeri benshi barangiza bakeneye guhitamo hagati yo guhitamo silicone cyangwa EPDM. Biragaragara ko dukunda silicone (!) Ariko byombi bihuza bite? EPDM ni iki kandi niba ubona ukeneye guhitamo hagati yombi, uhitamo ute? Dore ubuyobozi bwihuse-umuriro kuri EPDM…

 

EPDM ni iki?

EPDM isobanura Ethylene Propylene Diene Monomers kandi ni ubwoko bwa reberi yubucucike bukabije. Ntabwo irwanya ubushyuhe nka silicone ariko irashobora kwihanganira ubushyuhe bwo hejuru bugera kuri 130 ° C. Kubera iyo mpamvu ikoreshwa nkibigize inganda zitandukanye zirimo inganda, ubwubatsi n’imodoka. Mu bushyuhe bwo hasi, EPDM izagera aho igabanutse kuri -40 ° C.

EPDM irazwi kandi nka reberi yo hanze kuko irwanya ikirere harimo aside na alkali irwanya. Nkibyo, mubisanzwe uzasanga bikoreshwa mubintu nkidirishya nikirango cyumuryango cyangwa impapuro zidakoresha amazi.

EPDM ifite kandi abrasion nziza, igabanya imikurire no kurwanya amarira.

 

Ni iki kindi silicone ishobora gutanga?
Mugihe silicone na EPDM bisangiye ibintu byinshi nko kurwanya ibidukikije byiza, hariho kandi itandukaniro ryinshi ryingenzi kandi ni ngombwa kubyemera mugihe ufata ibyemezo byubuguzi.

Silicone ni uruvange rwa karubone, hydrogène, ogisijeni na silicone kandi iyi mvange itanga inyungu nyinshi EPDM idakora. Silicone irwanya ubushyuhe bwinshi, ibasha kwihanganira ubushyuhe bugera kuri 230 ° C mugihe ikomeza imiterere yumubiri. Ikirenzeho, ni na elastomer sterile kandi nkuko ikunzwe mubikorwa byibiryo n'ibinyobwa. Mubushyuhe bwo hasi silicone nayo irenze EPDM kandi ntizagera ahantu hacitse kugeza -60 ° C.

Silicone nayo irambuye kandi itanga uburebure burenze EPDM. Irashobora kandi gutegurwa kugirango irinde amarira nka EPDM. Izi ngingo zombi zituma biba byiza gukoreshwa nka membrane vacuum mumashini zikoreshwa mugukora imirasire yizuba hamwe nibikoresho byogejwe, bikunze kwitwa imashini ikora vacuum.

Silicone ni elastomer ihamye kandi nkigisubizo abaguzi bumva ko silicone ari nziza nkigisubizo cyizewe cyigihe kirekire kubera iki. Nubwo silicone igaragara nkigiciro cyinshi muri byombi, ubuzima bwa EPDM burigihe buba bugufi kuruta ubwa silicone bityo bugomba gusimburwa mubisabwa kenshi. Ibi bivamo igiciro kirekire kirenze icya silicone.

Hanyuma, mugihe EPDM na silicone byombi bizabyimba biramutse bishyizwe mumavuta igihe kinini mubushyuhe bwinshi, silicone irwanya amavuta yibiribwa mubushyuhe bwicyumba niyo mpamvu ikoreshwa mugutunganya amavuta yibiribwa nka kashe na gasike yo gutunganya imashini.

 

Nigute ushobora guhitamo byombi?
Mugihe iyi mfashanyigisho ngufi yerekana muri make itandukaniro riri hagati yuburyo bubiri bwiza bwo kumenya reberi ukeneye ni ugusobanukirwa intego yo gukoresha no kuyishyira mubikorwa. Kumenya uburyo uzashaka kubikoresha, ibihe bizakurikizwa nuburyo ukeneye kubikora bizagufasha kubona neza neza kubijyanye na reberi wahitamo.

Kandi, menya neza gusuzuma ibintu nkimbaraga, ubworoherane nuburemere ibikoresho bizakenera kwihanganira kuko nabyo bishobora kuba ibintu byingenzi bifata ibyemezo. Mugihe ufite aya makuru atuyobora neza kuri Silicone Rubber vs EPDM irashobora kuguha amakuru yimbitse ukeneye kugirango wiyemeze bwa nyuma.

Niba wifuza kuganira kumushinga wawe hamwe numwe mubagize itsinda ryacu noneho umuntu ahora aboneka. Twandikire.
