Rubber uli ndi zinthu zabwino kwambiri zochepetsera, zomwe zimagwiritsidwa ntchito kwambiri popanga kuchepetsa kugwedezeka kwa mayamwidwe kapena kudzipatula kwa zinthu zomwe zimachepetsa kugwedezeka. Ndi chitukuko chofulumira cha sayansi yamakono ndi zamakono ndi kupita patsogolo kwa chikhalidwe cha anthu, komanso chidwi cha anthu ku zoopsa za chivomezi, zinthu zowononga mphira zikuchulukirachulukira zogwiritsidwa ntchito, zofunikira zake zikuchulukirachulukira.
Compressor vibration damping pad imayikidwa pansi pa kompresa, kuthandizira zigawo zazikulu za kompresa, zofunikira zonse za moyo wautumiki wa zaka pafupifupi 10 komanso m'moyo wa zofunikira za kutalika kwa pedi, kuuma, kukula kwapang'ono, chifukwa kompresa imapachikidwa panja, kotero kuti mphira wa rabara pad nyengo kukana zofunika ndi mkulu, ndipo amafuna kuuma kwa pad ndi kutentha otsika.
Kugwira ntchito kwa mphira kumakhudza mwachindunji mphamvu ya kompreta kugwedera ndi phokoso, kotero kuti, kugwedezeka kwa mphira khushoni ndikosavuta kowongolera mpweya 'wobiriwira komanso wochezeka ndi gawo lofunikira la'. Kutengera ntchito ya mphira mantha PAD ndi ntchito ya elasticity mkulu mphira ndi mkulu mamasukidwe akayendedwe kukhazikika mu umodzi, mogwira akatembenuka mawotchi mphamvu mu kinetic mphamvu ya maselo kayendedwe, ndi mamolekyu mphira wa mapindikidwe ndi kubwezeretsa kwa mawotchi mowa mphamvu, ndipo kuchepetsa kugwedera ndi phokoso. Kugwedera-kugwetsa mphira khushoni yaitali ntchito panja, pakufunika kukhala wokhazikika dimensional, kukana nyengo ndi kuuma ndi kutentha kusintha si zoonekeratu makhalidwe.
Chloroprene rabara (CR) imakhala ndi nyengo yabwino yolimbana ndi nyengo, ndi ntchito yabwino komanso yotsika mtengo. Mayiko ambiri otukuka amaika patsogolo kugwiritsidwa ntchito kwake ngati mphira wothira mphira, monga mphira waku Japan wa compressor fakitale ya vibration damping cushion (yofanana ndi miyezo yapanyumba), yomwe imapereka kugwiritsa ntchito rabala ya chloroprene. Cholinga cha kafukufukuyu ndi chitukuko ndikusankha giredi yoyenera ya rabara ya neoprene ndi wothandizira wofewa, ndikuwunika momwe zimapangidwira, kukalamba komanso kukhazikika kwake.
1. Zotsatira za mitundu yosiyanasiyana ya CR pa ntchito ya mphira
Mapadi owopsa okhudzana ndi kukana kukalamba komanso zofunikira zotsika kutentha, ndipo ayenera kuganizira mtengo, kusankha kwa DCR2131, CR3221 ndi CR2321 mitundu itatu ya magiredi. Zomwezo ndi mphira, mphira wa CR2321 pansi pa zinthu zakuthupi ndi zamakina ndizabwinoko, koma kukana kukalamba kumakhala koipitsitsa pang'ono, sikunakumane ndi ukadaulo; DCR2131 mphira ntchito kufika zizindikiro zofunika, koma ndondomeko kusanganikirana si zabwino, mphira ndi yofewa kwambiri, woonda mwa zovuta kwambiri, zosavuta kutsogolera mchitidwe wosakanikirana kusanganikirana. Chifukwa otsika mamasukidwe akayendedwe a kusakaniza mphira Mooney, mphira mu vulcanization n'zovuta kusaganizira mpweya, chifukwa mankhwala thovu padziko, zimakhudza mlingo kuyenerera mankhwala; ndi CR3221 mphira magwiridwe antchito kuti akwaniritse zofunikira zaukadaulo.
2. Chikoka cha zofewa zosiyanasiyana pa ntchito ya zinthu mphira
Chifukwa cha kompresa pa kugwedera damping khushoni kuuma wapadera, adzakhala m'munsi kuuma (Madigiri A40 m'mphepete mwa nyanja), kotero zofunika za softener ndi wovuta kwambiri ndi kuchuluka komanso ndi lalikulu, ndi dongosolo zimakhudza kwambiri ntchito ya mphira ndi mankhwala. Pa nthawi yomweyo kuganizira mtengo ndi gwero, anasankha nthumwi DOTP, mafuta aromatics, epoxy soya soya mafuta softener mu CR3221 zakuthupi mphira kwa zoyesera poyerekeza, chifukwa ntchito aromatics mafuta mphira zinthu kuuma ndi mkulu, mu aromatics chilinganizo mafuta ntchito 39, zotsatira za ntchito DOTP kapena mafuta onunkhira ntchito mphira akhoza kukumana ndi zofunikira za mphira mafuta akhoza kukumana ndi mphira luso lavu. kugwiritsa ntchito mphira wa DOTP sikophweka kumata zodzigudubuza, kusakaniza kosavuta, ndipo zotsatira za kugwiritsa ntchito DOTP kapena mafuta onunkhira ochiritsa mphira amatha kukwaniritsa zofunikira zaukadaulo. Ndikosavuta kusakaniza, ndikuganiziranso chomera cha kompresa ku certification ya RosH 'Kuletsa kugwiritsa ntchito zinthu zina zowopsa pazida zamagetsi ndi zamagetsi ' ndi REACH certification 'pakulembetsa, kuwunika, kuvomereza ndi kuletsa dongosolo lamankhwala' zofunikira zachilengedwe, kotero DOTP ndiye chisankho chabwino kwambiri!
