Izinto zangaphakathi nangaphandle zokuguga kwe-rubber hose

I-hose ye-rubber luhlobo lombhobho oguquguqukayo owenziwe ngezinto zerabha. Inokuguquguquka okuhle kunye nokunwebeka kwaye inokuthwala uxinzelelo kunye noxinzelelo oluthile. Imibhobho yeRubber isetyenziswa ngokubanzi kwi-petroleum, ikhemikhali, i-mechanical, i-metallurgical, i-marine kunye nezinye iindawo, ezisetyenziselwa ukuthutha ulwelo, igesi kunye nezixhobo eziqinileyo, ngokukodwa kwisidingo sokwakheka okuguquguqukayo kunye nokufakwa kweso sihlandlo kudlala indima ebalulekileyo.

Ekusetyenzisweni kwemibhobho yerabha, iipropathi zerabha ziya kutshintsha ngenxa yempembelelo ebanzi yezinto ezahlukeneyo, eziya kubangela ukuba iipropathi zerabha kunye neemveliso zayo zinciphe ngokuthe ngcembe ngokutshintsha kwexesha de zonakaliswe kwaye ziphulukane nexabiso labo lokusebenzisa, le nkqubo ibizwa ngokuba kukuguga kwerabha. Ukuguga kwetyhubhu yerabha kuya kubangela ukulahleka kwezoqoqosho, kodwa ukunciphisa ezi lahleko, ngokuguga kancinci ukwandisa ubomi betyhubhu yerabha yenye yeendlela, ukuze sinciphise ukuguga, kufuneka siqale siqonde ezo zinto zibangela ukuguga kwetyhubhu yerabha. .

Umbhobho wokuguga

1. Ukusabela kwe-oxidation sesinye sezizathu ezibalulekileyo zokuguga kwerabha, i-oksijini iya kusabela ngezinye izinto kwi-tube yerubha, okukhokelela ekutshintsheni kweempawu zerabha.

2. Ukunyusa izinga lokushisa kuya kukhawulezisa ukusasazwa kwezondlo kunye nokunyusa izinga le-oxidation reaction, ukukhawuleza ukuguga kwerabha. Ngakolunye uhlangothi, xa izinga lokushisa lifikelela kwinqanaba elihambelanayo, i-rubber ngokwayo iya kuba ne-thermal cracking kunye nezinye iimpendulo, ezichaphazela ukusebenza kwerubha.

I-oxidation ibangela ukuguga

3. Ukukhanya kukwanawo namandla, okukhona amaza okukhanya amfutshane, kokukhona abe namandla. Enye ye-ultraviolet ukukhanya okuphezulu kwamandla, i-rubber inokudlala indima eyonakalisayo. I-radical yamahhala yerabha yenzeka ngenxa yokufunxwa kwamandla okukhanya, okuqalisa kunye nokukhawulezisa i-oxidation chain reaction. Kwelinye icala, ukukhanya kukwadlala indima ekufudumezeni.

4. Xa i-rubber ibonakaliswe kumoya omanzi okanye ifakwe emanzini, izinto ezixutywe ngamanzi kwi-rubber ziya kukhutshwa kwaye zichithwe ngamanzi, ngokukodwa kwimeko yokucwiliswa kwamanzi kunye nokubonakaliswa kwe-atmospheric, kuya kukhawuleza ukutshatyalaliswa kwerubha.

5. Irabha iphindaphindwa isenzo, ikhonkco lemolekyuli yerabha inokwaphuka, iqokelele kuninzi inokubangela ukuqhekeka kwetyhubhu yerabha kwaye iphuke.

Ezi zizinto eziza kubangela ukuguga kwe-hose ye-rubber, ukubonakala kokuqhekeka okuncinci kukusebenza kokuguga, i-oxidation eqhubekayo iya kwenza i-hose ye-rubber surface brittle. Njengoko i-oxidation iqhubeka, umaleko we-embrittlement uya kuba nzulu, obonisa ukusetyenziswa kwe-micro-cracks kubonakala ekugobeni. Kule meko, kufuneka kube yithumbu ngexesha elifanelekileyo.
