6. EPDM EPDM reberi ifunga impeta

Irwanya amazi, irwanya imiti, irwanya ozone, kandi irwanya ikirere. Ikora neza mugushiraho porogaramu zirimo alcool na ketone kimwe nubushyuhe bwo hejuru bwamazi. Ubushyuhe busanzwe bwo gukora ni -55 kugeza 150 ° C.

7. Impeta ya CR neoprene

Irashobora kwihanganira cyane cyane ikirere nizuba. Irwanya aside irike hamwe na silicone yamavuta yo kwisiga, kandi ntabwo itinya firigo nka dichlorodifluoromethane na ammonia. Kurundi ruhande, yaguka cyane mumavuta yubutare hamwe na aniline nkeya. Ubushyuhe buke butuma korohereza no gukomera byoroshye. Birakwiriye kurwego rwikirere, izuba, na ozone byerekanwa kimwe nuburyo butandukanye bwa chimique na flame birwanya kashe. Koresha hamwe na acide ikomeye, nitrohydrocarbone, esters, ketone, hamwe na chloroform ntabwo ari byiza. Ubushyuhe busanzwe bwo gukora ni -55 kugeza 120 ° C.

8. IIR butyl rubber ifunga impeta

Ikora neza cyane mubijyanye no gukomera kwikirere, kurwanya ubushyuhe, kurwanya UV, kurwanya ozone, no kubika; byongeye kandi, irashobora kwihanganira guhura nibikoresho bya okiside hamwe namavuta yinyamanswa nimboga kandi ikagira imbaraga zo kurwanya imishwarara ya polar harimo alcool, ketone, na est est. Bikwiranye nibikoresho byo kurwanya vacuum cyangwa imiti. Ntabwo ari byiza kuyikoresha hamwe na kerosene, hydrocarbone ya aromatic, cyangwa amavuta ya peteroli. -50 kugeza 110 ° C nubusanzwe ubushyuhe bukora.

9. ACM acrylic rubber ifunga impeta

Kurwanya ikirere cyayo, kurwanya peteroli, hamwe nigipimo cyo guhindura ibintu byose biri munsi yikigereranyo, icyakora imbaraga za mashini, kurwanya amazi, hamwe nubushyuhe bwo hejuru ni byiza cyane. Mubisanzwe biboneka muri power power na gearbox ya sisitemu yimodoka. Ntabwo bisabwa gukoreshwa hamwe na feri ya feri, amazi ashyushye, cyangwa fosifate. Ubushyuhe busanzwe bwo gukora ni -25 kugeza 170 ° C.

10. NR isanzwe ya reberi ifunga impeta

Ibikoresho bya reberi birakomeye kurwanya kurira, kurambura, kwambara, no gukomera. Cyakora, gusaza vuba mu kirere, gukomera iyo bishyushye, kwaguka byoroshye, gushonga mumavuta yubutare cyangwa lisansi, kandi birwanya aside yoroheje ariko ntibikomeye alkali. Birakwiye gukoreshwa mumazi hamwe na hydroxyl ion, nka Ethanol na feri yimodoka. -20 kugeza 100 ° C nubusanzwe ubushyuhe bukora.

11. PU polyurethane reberi ifunga impeta

Rubber ya polyurethane ifite imiterere myiza yubukanishi; irusha izindi reberi mubijyanye no kwambara no kwihanganira umuvuduko mwinshi. Kurwanya gusaza, ozone, namavuta nabyo ni byiza cyane; ariko, ku bushyuhe bwo hejuru, birashoboka hydrolysis. Mubisanzwe bikoreshwa mugushiraho ikimenyetso gishobora kwihanganira kwambara numuvuduko mwinshi. Ubushyuhe busanzwe bwo gukora ni -45 kugeza 90 ° C.
