Kodi mungayendetse bwanji kutentha kapena kutentha?

Kukana kuwedza kutentha kapena kukalamba kwa kutentha kukufunika kwambiri, makamaka pakugwiritsa ntchito kwa magalimoto komwe magawo a mphira amagwiritsidwa ntchito kwambiri pamalo ophimbidwa ndi matenthedwe ozungulira. Opanga magalimoto amva kukakamizidwa kuti atumikire kwa nthawi yayitali amakhala ndi ziwalo zawo za mphira. Anaerobic kutentha katundu ndi kutentha ndi malo okalamba ndi osiyana. Mphirayo ili ndi kutentha kwa kutentha, koma mwina sakanatha kulimbana ndi oxygen.

Chidziwitso: Protocol iyi yoyesererayi silingagwire ntchito iliyonse. Chimodzi chilichonse cha zosintha zomwe zingakuthandizeni kuthana ndi vuto kapena kukalanda kutentha kumathandizira zinthu zina, mwina kuti zikhale bwino kapena zoyipa.

1. Offertluoelastomer

2, mphira wa fluorine

Fluorine rabara fkm imakhala ndi kukana kwabwino kwambiri, ndipo itha kugwiritsidwa ntchito pa kutentha mpaka 260 ℃. Pofuna kulimbikitsanso kutentha kwambiri kukana kwa mphira wa fluorine, muyenera kusankha kuvomereza kwa acid (acid) Posankha Bisphenol AFI monga Vuto la Vulcananition, kukalamba kwa kutentha kwa mphira kumakhala kwabwinoko. Kugwiritsidwa ntchito mu magetsi owononga injini yamagetsi, kukalamba kutentha kwa fluorostastomer opangidwa kuchokera ku vitylidene fluoride, tetrafluofentlenerathylenene ndipo Pulogalamu ndiyabwino kuposa phwiriroorostomestomer. Izi zimachitika chifukwa cha hexafluoropropyylene ndi propylene pakupanga kwa polymerization.

3, Hnbr

Kukwera kwambiri kwa hydrogenation, ndibwino kukana kutentha kwa hnrb, chifukwa palinso kulumikizana kawiri konse pa unyolo waukulu womwe sukhazikika. Ma hnbr ena amatha kukhalabe okhwima ndi sulfur chifukwa amakhalabe ndi maubwenzi awiri osavomerezeka. Komabe, ngati paipitsidwa ndi peroxide, kukana kutentha kwapakatikati kumatha. Kwa Hnbru Mbewu, Totm imatha kupatsanso kutentha kuposa dop yotsika chifukwa cha kuchuluka kotsika komanso kulemera kwambiri kwa ma piciretive a triocyl.

4. Neoprene

W-Lepre neoprene ali ndi vuto lokalamba kuposa G-Typen Neoprene. Dischenyllamine octanoate ndi antioxidant ya neoprene, yomwe imatha kusintha kutentha kwa kutentha.

5, Epdm

EPDM idzakhalabe ndi kutentha kotentha pa 125 ℃ pambuyo poti kuli koyenera. Kugwiritsa ntchito EPROXID PILMM Spdm Spdm, kungapangitse mphira kukhala ndi kutentha kwabwino.

6, ma vinya otsika a Vapor a Phase FDM

Zambiri za Ethylene ndi Ultrance Vapor Gawo la Epiro, lomwe limatha kudzazidwa ndi mafayilo ambiri, chifukwa cha zomwe zili mu Ethylene, zikuyenera kupanga mphira kukhala ndi zokongoletsa zabwino, motero kutentha kwa mphira kumatha.

7, pewani kugwiritsa ntchito styrene utoto

Pewani kuwonjezera styrene utoto wa mphira wogwiritsidwa ntchito kutentha kwambiri.

8, tilcum ufa

Mu mphira wa Epdm Hose, Tulutsani 40% ya kaboni wakuda ndi talcum ufa, womwe umatha kusintha kukana kwa kukalalika kwa mphira. Maphunziro ena a Tilcum ali ndi zabwino zambiri kuposa omwe amathandizidwa kapena omwe alibe vuto lililonse pankhaniyi.

9, pyapu ya maonedwe apamwamba kwambiri

Mkati mwa maphikidwe, magudukidwe apamwamba a Vicconcy amatha kupatsana bwino kwambiri kuposa maofesi a viscts. Chifukwa chopitiritsa kwambiri cha ma Isccluzer nthawi zambiri chimakhala cholemera kwambiri, osasavuta kusanzira, mokhazikika komanso kukana kwabwino.

10, kugwiririra mafuta a mbeu ya neoprene

Pofuna kupanga neoprene kukhala ndi mphamvu yabwino, mafuta a canola amafunikira chifukwa chimawoneka ngati mafayilo otsika, omwe amapangitsa kuti mphira kukhala ndi vuto lotsika komanso lotsika.

11, ogwira ntchito a EV / Semi-Ogwira ntchito a Spev

Mu dongosolo logwira ntchito kapena la Semi-Vutoli logwira, kuchuluka kwa ma sulfur ndi okwera, ndiye kuti, ' Chiwerengero cha sulufule umodzi ndi sulufule kawiri ndi chachikulu kuposa chomangira cha sulufur, chifukwa chake, kukhazikika kwa kutentha kwa mphira kumayendetsedwa ndipo kukalamba kutentha kumachitika.

12, zinc oxide

Valcananiza / sulforamide kuwonongeka kwa mphira, wodzazidwa ndi zinc oxide, amatha kupereka mphira wabwino kutentha komanso kukana kwa Sulfur.

13, peroxide wamba

Mu Peroxide Voxanired EPDM Courcour, ZMti imasankhidwa ngati antioxidant, yomwe imatha kupatsa moddus yapamwamba kwambiri ndi kukana kwamphamvu.
