Tekinoroji yemotokari inogadzirwa, zvinhu zvekukwesha zvinhu zvakare zvakagadziriswa munzira yese, zvakanyanya kukamurwa kuita akati wandei mapoka makuru:
Organic brake pad
Pamberi pemakore ekuma1970, mabhureki mapedhi aive nenhamba yakawanda yemidziyo yeasbestos, inotora kupisa kwakanyanya, kuramba moto, uye hunhu hwekupokana, asi nekuda kwekuti hupfu hunogadzirwa neasbestos mukugadzira nekushandisa, kune kwakasiyana kukuvara kumuviri wemunhu. , izvo zviri nyore kukonzera maitiro ekufema.Zvirwere zvinotoita carcinogenic, saka mabhureki ekotoni parizvino akarambidzwa nepasirese.
Zvadaro, ikozvino organic brake pads inowanzonzi NAO brake pads (Non-Asbestos Organic, isina dombo-isina organic brake pads), iyo inowanzo ine 10% -30% yezvinhu zvesimbi, uye inosanganisirawo tambo dzezvirimwa, girazi Fibers, kabhoni, rabha, girazi uye zvimwe zvinhu.
Iyo organic brake pads yakavandudza mashandiro mukupfeka uye kudzora ruzha kuburikidza nemakore mazhinji ekusimudzira uye kugadzirisa zvinhu, asi zvakare akakodzera kutyaira zuva nezuva.Iyo guruva rinogadzirwa uye kukuvadzwa kwebhureki disc kushoma.Nekudaro, nekuda kwemutengo wezvinhu, nezvimwewo, iyo organic brake firimu rinowanzo kudhura, uye yekutanga fekitori inowanzo shandiswa pane yepakati uye yepamusoro-yekupedzisira modhi.
Semi-metal brake pad
Iyo inonzi hafu yesimbi inonyanya mune friction material inoshandiswa mumabhureki mapedhi akadaro, kubva pa30% -65% yesimbi - kusanganisira mhangura, iron, nezvimwewo. Hunhu hweiyi brake pad inonyanya kutonhorera, kupisa kwekushisa kwakanyanya, mutengo wakaderera, uye kushata kunokonzerwa nezvikonzero zvenyama, ruzha panguva yemabhureki ruchave rwakakura, uye kupfeka kwesimbi kune bhureki disc kuchave kwakakura.Sezvo semi-metal brake pad ine hunhu hwedu pamusoro, pane kunyanya maviri makuru maapplication, imwe ndiyo fekitori yepakutanga inotsigira mabhureki emhando yepakati uye yakaderera-yekupedzisira - iyi hunhu ndiyo yakaderera mutengo.Imwe nzira iri kunyanya mumunda weganda rakagadziridzwa rakaputika - nokuti mabheki esimbi akanaka, anonyanya kukodzera kumotokari dzepamusoro kana muzviitiko zvakasiyana-siyana.Mushure mezvose, nenzira iyi yekushandiswa, kupisa kwakanyanya kweganda rakaputika kuchasvika kunyange kupfuura 800 degrees Celsius.Saka isu tinogona kuona kuti akawanda akagadziridzwa mabhureki ane yakakwirira simbi zvinhu zvemabhureki ekutyaira kunotyisa uye zviitiko.
