Rubber hose imhando yepombi inochinjika yakagadzirwa nerubha zvinhu. Iyo ine yakanaka kuchinjika uye elasticity uye inogona kutakura kumwe kudzvanywa uye tension. Rubber hoses inoshandiswa zvakanyanya mu petroleum, makemikari, mechanical, metallurgical, marine uye mamwe minda, inoshandiswa kutakura mvura, gasi uye zvinhu zvakasimba, kunyanya mukudiwa kwekugadziriswa kwekugadziriswa uye kuiswa kwechiitiko kunoita basa rinokosha.
Mukushandiswa kwemahosi erabha, zvimiro zverabha zvinoshanduka nekuda kwesimba rakazara rezvinhu zvakasiyana-siyana, izvo zvinozoita kuti zvimiro zverabha uye zvigadzirwa zvaro zvideredze zvishoma nezvishoma nekuchinja kwenguva kusvika zvakuvadzwa uye kurasikirwa nekukosha kwekushandisa. nzira iyi inonzi kuchembera kwerabha. Kuchembera kwerubha chubhu kuchakonzera kurasikirwa kwehupfumi, asi kuderedza kurasikirwa uku, kuburikidza nekunonoka kuchembera kuwedzera hupenyu hwerubha chubhu ndeimwe yenzira, kuitira kuti tinonoke kuchembera, tinofanira kutanga tanzwisisa izvo zvinhu zvinokonzera kuchembera kwerubha chubhu. .
Kuchembera hosi
1. Oxidation reaction ndechimwe chezvikonzero zvakakosha zvekukwegura kwerabha, okisijeni ichaita nezvimwe zvinhu muchubhu yerubha, zvichiita kuti kuchinja kwerabha zvinhu.
2. Kuwedzera tembiricha kuchamhanyisa kupararira kwezvinovaka muviri uye kukurumidza chiyero che oxidation reaction, kukurumidza kuchembera kwerabha. Kune rimwe divi, kana tembiricha yasvika padanho rinoenderana, rabha pachayo ichava nekuputika kwemafuta uye mamwe maitiro, ayo anokanganisa kushanda kwerabha.
Oxidation inokonzera kukwegura
3. Chiedza chinewo simba, kupfupika kwesaisai rechiedza, ndiko kuwedzera simba. Imwe ye ultraviolet chiedza chepamusoro-simba, rubber inogona kuita basa rinoparadza. Iyo yemahara radical yerabha inoitika nekuda kwekupfekwa kwesimba rechiedza, iro rinotanga uye rinomhanyisa iyo oxidation chain reaction. Kune rumwe rutivi, chiedza chinoitawo basa mukupisa.
UV kukuvadza kune rabha
4. Apo rubha rinoratidzwa nemhepo yakanyorova kana kunyudzwa mumvura, zvinhu zvinonyunguduka mumvura murubha zvichabviswa uye zvakanyungudutswa nemvura, kunyanya munyaya yekunyudzwa kwemvura uye kusvibiswa kwemhepo, ichakurumidza kuparadzwa kwerubha.
5. Rubber inodzokororwa chiito, iyo rubber molecular chain inogona kuputsa, kuunganidza mune dzakawanda inogona kukonzera rubber tube kutsemuka uye kunyange kuputsika.
Izvi ndizvo zvinhu zvinotungamirira kukwegura kwebhoti rerubha, kuonekwa kwekuputika kuduku ndiko kukwegura kwekuita, kuenderera mberi kwe oxidation kuchaita kuti rubber hose pamusoro brittle. Sezvo iyo oxidation ichienderera mberi, iyo embrittlement layer inodzika zvakare, ichiratidza kushandiswa kwema micro-cracks kuoneka mukukotama. Muchiitiko ichi, inofanira kuva nenguva yekutsiva hose.
