Rabha reNitrile
Rabha yeNitrile, inonziwo nitrile-butadiene rabha (NBR, Buna-N), irabha yakagadzirwa nesimbi inoita kuti mafuta epetroleum asashande zvakanaka pamwe nemafuta emineral nemiriwo. Rabha yeNitrile inodzivirira zvakanyanya kupfuura rabha yechisikigo kana zvasvika pakukwegura kwekupisa - kazhinji mukana mukuru, sezvo rabha yechisikigo inogona kuoma uye kurasikirwa nekugona kwayo kunyorovesa. Rabha yeNitrile isarudzo yakanaka yezvinhu zvinoshandiswa zvinoda kuramba kukweshwa uye kunamira kwesimbi.
Rubha re nitrile rinoshandiswa sei?
Rabha yeNitrile inoshanda zvakanaka mumadhiragi ecarburetor nemapombi emafuta, mapombi endege, zvisimbiso zvemafuta nemagasket pamwe nemachubhu akafukidzwa nemafuta. Nekuda kwekushanda kwayo kwakasiyana-siyana uye kuramba kwakasimba, zvinhu zveNitrile zvinoshandiswa kwete mukushandiswa kwemafuta, mafuta uye makemikari chete, asiwo mukushandiswa kunoda kuramba kupisa, kukwesha, mvura, uye kupindira kwegasi. Kubva kumarigi emafuta kusvika kumabowling alleys, rabha yeNitrile inogona kuva chinhu chakakodzera kushandiswa kwako.

Mashandisirwo
Hunhu hwerabha yeNitrile hunoita kuti ive mhinduro yakanaka kwazvo yekuvhara. Ine simba guru rekudzivirira zvigadzirwa zvepeturu uye inogona kuwedzerwa kuti ishande pakupisa kusvika ku250°F (121°C). Nekudzivirira kupisa uku, mishonga yerabha yeNitrile yakakodzera inogona kutsungirira kushandiswa kwemotokari dzese kunze kwedzakanyanya kuoma. Mamwe mashandisirwo anobatsira kubva kuhunhu hwerabha yeNitrile inogona kugadzirwa nekugadzirwa nekugadzirwa anosanganisira:
♦ Kushandiswa kunodzivirira mafuta
♦ Kushandiswa kwekupisa kwakaderera
♦ Masisitimu emafuta emotokari, emugungwa uye endege
♦ Zvivharo zveNitrile roll
♦ Mapombi emvura
♦ Tubhu reNitrile
Mienzaniso yemashandisirwo nemaindasitiri uko nitrile (NBR, buna-N) inoshandiswa inosanganisira:
Indasitiri yeMotokari
Nitrile, inozivikanwawo sebuna-N, ine hunhu hunodzivirira mafuta zvinoita kuti ive chinhu chakakwana pasi pehood.
Buna-N inoshandiswa pakurapa
♦ Magasket
♦ Zvisimbiso
♦ Mhete dzeO
♦ Diaphragms dzeCarburetor nepeturu
♦ Masisitimu emafuta
♦ Mapombi emvura
♦ Kuisa machubhu
Indasitiri yeBowling
Rabha yeNitrile (NBR, buna-N) haipindi mafuta emumugwagwa uye inowanzo shandiswa pakurapa
♦ Vagadziri vemapini ekubhowa
♦ Mabhampa anotenderera
♦ Chero chinhu chipi zvacho chinosangana zvakananga nemafuta emumugwagwa
Indasitiri yeOiri neGasi
♦ Zvisimbiso
♦ Kuisa machubhu
♦ Maumbirwo akaumbwa
♦ Zvikamu zvakabatana nerabha nesimbi
♦ Zvinobatanidza rabha
Mabhenefiti & Zvakanakira
Nitrile inodzivirira kupisa zvakanyanya - mukana mukuru pane rabha yechisikigo kumaindasitiri emotokari nebowling.
Mabhenefiti ekushandisa nitrile rabha:
♦ Mhinduro yakanaka kwazvo yekuvhara mashandisirwo
♦ Seti yakanaka yekudzvanya
♦ Kuramba kweAbrasion
♦ Simba rekusimba
♦ Kuramba kupisa
♦ Kuramba kukweshwa
♦ Kuramba mvura
♦ Kuramba kubvumidzwa kwegasi
Chenjero: Nitrile haifanirwe kushandiswa muzvinhu zvine polar solvents zvakaita seacetone, MEK, ozone, chlorinated hydrocarbons uye nitro hydrocarbons.
