Rubber Brake Hose 1/8 sae j1401 DOT SAE Hydraulic High Pressure Brake Hose

Kodi NBR ndi chiyani?

Nitrile butadiene rabara (NBR), ndi copolymer wa acrylonitrile ndi butadiene monomer polymerization, makamaka opangidwa ndi otsika kutentha emulsion polymerization, kukana mafuta kwambiri, kukana kuvala mkulu, kukana kutentha, kukana mwamphamvu. Zoyipa zake ndi kukana kutentha kochepa, kukana kwa ozoni, kusagwira bwino ntchito, kutsika kwamphamvu.

Chifukwa cha kukana kwake kwamafuta komanso mawonekedwe ake abwino komanso amakina, NBR imagwiritsidwa ntchito kwambiri popanga mafuta osamva ngati zinthu za rabara. Monga O-mphete, gasket, payipi ndi mafuta thanki akalowa mphira, wodzigudubuza kusindikiza, akalowa thanki, insulating pansi bolodi, mafuta kugonjetsedwa yekha, mbali zolimba mphira, nsalu ❖ kuyanika, chitoliro ulusi zoteteza wosanjikiza, mpope impeller ndi waya m'chimake, zomatira, chakudya ma CD filimu, magolovesi mphira ndi zina. Kudziko lina makamaka amagwiritsidwa ntchito pa ndege, galimoto, kusindikiza, kupanga nsalu ndi makina, ndi zina zotero. Ndi chitukuko cha mitundu yosinthidwa ya NBR, chiyembekezo cha ntchito ya rabara ya nitrile butadiene chikukulitsidwa. Mwachidule chachidule: kupanga machubu amafuta, nsalu zamafuta, chisindikizo chamafuta, chitoliro chamafuta, zida za mphira zosagwira mafuta komanso kukhudzana kwamafuta ndi mitundu yonse yazinthu. Nitrile mphira makamaka ntchito mafuta kugonjetsedwa mankhwala, monga chitoliro mafuta, tepi, filimu mphira ndi thumba lalikulu la mafuta, nthawi zambiri ntchito kupanga mitundu yonse ya mankhwala kugonjetsedwa mafuta akamaumba, monga O-mphete, mafuta chisindikizo, mbale chikopa, diaphragm, valavu, mvuvu, payipi mphira, zisindikizo, thovu, etc., komanso kuvala - kukana mbale ndi mphira.

Chifukwa chiyani rabaraananyema payipiali ndi mzere woluka nayiloni?

Pogwiritsa ntchito mphira wa nayiloni ndi mphira wa chlorinated butyl monga mawonekedwe amkati ndi akunja, amatha kupanga mtundu watsopano wa payipi kuti mupewe kutayikira kwa mpweya wa freon, kupangitsa kuti chitolirocho chikhale cholimba.

Zinthu zokalamba za rabara:

1. Oxygen: Oxygen mu rabala yokhala ndi mamolekyu a rabala mu free radical chain reaction, ma molecular chain break kapena crosslinking kwambiri, zomwe zimapangitsa kusintha kwa labala.

2. Ozone: Zochita za mankhwala a ozoni kuposa okosijeni ndizokwera kwambiri, zowononga kwambiri, ndikuphwanya unyolo wa maselo, koma zochita za ozoni pa mphira wokhala ndi mphira wopindika ndizosiyana.

3. Kutentha: Kupititsa patsogolo kuchuluka kwa mpweya wa okosijeni ndi kuyambitsa makutidwe ndi okosijeni, kuti mupititse patsogolo kuthamanga kwa mphira wa okosijeni, chomwe ndi chinthu chodziwika bwino cha kukalamba - kukalamba kwa oxygen.

4. Kuwala: Kufupika kwa mafunde a kuwala, kumakhala kolimba kwambiri. Ndi ultraviolet yamphamvu kwambiri yomwe imawononga mphira. Kuphatikiza pakuyambitsa mwachindunji kusweka ndi kulumikizana kwa unyolo wa raba, mphira imatenga mphamvu yowunikira ndikupanga ma radicals aulere, omwe amayamba ndikufulumizitsa njira ya oxidation chain reaction, yomwe imatchedwa "light outer layer crack".

5. Madzi: udindo wa madzi ndi mbali ziwiri: mphira mu chonyowa mpweya mvula kapena ankawaviika m'madzi, zosavuta kuwononga, izi ndi chifukwa cha zinthu sungunuka madzi mu mphira ndi magulu hydrophilic ndi zigawo zina ndi madzi m'zigawo ndi kuvunda, hydrolysis kapena mayamwidwe ndi zifukwa zina. Makamaka pansi pa kusinthana kwa kumiza m'madzi ndi kuwonetseredwa mumlengalenga, chiwonongeko cha mphira chidzafulumizitsa. Komabe, nthawi zina, madzi samawononga mphira, ndipo amakhala ndi zotsatira zochedwetsa ukalamba.

7. Mafuta: Pogwiritsira ntchito njira yolumikizirana kwanthawi yayitali ndi sing'anga yamafuta, mafuta amatha kulowa mu rabala kuti atukuke, zomwe zimapangitsa kuchepa kwa mphamvu ya mphira ndi zinthu zina zamakina. Mafuta akhoza kupanga mphira kutupa, chifukwa mafuta mu mphira, opangidwa maselo kufala, kuti vulcanized mphira maukonde dongosolo kusintha.
