Inqubo yokuguga kwerabha iyithinta kanjani ikhwalithi yayo?

Ukuqalisa

I-Rubber, impahla eguquguqukayo esetshenziswe kabanzi kuyo yonke imboni, yenza inqubo yokuguga kwemvelo engathinta kakhulu ikhwalithi nokusebenza kwayo. Le nto ibalulekile ukuze iqonde, njengoba ithinta ngqo ukuqina nokusebenza kwemikhiqizo yenjoloba kuzinhlelo zokusebenza ezivela ezimotweni kuya ku-aerospe. Inqubo yokuguga ithonywa yizici ezahlukahlukene, kufaka phakathi izimo zemvelo, ukuvezwa kwamakhemikhali kanye nokuxineka kwemishini. Ngokukhetha izinkampani zokuguga kwenjoloba, singakwazi ukuthuthukisa amasu wokunciphisa imiphumela yaso futhi sithuthukise isikhathi eside sokwaziswa. Ukuhlolwa okujulile kwezicelo ezahlukahlukene zenjoloba, vakashela Okokuhlikihla.

Ukuqonda ukuguga kwenjoloba

Izinguquko zamakhemikhali nezingokomzimba

Ukuguga kweRubber kubonakaliswa zombili izinguquko zamakhemikhali nangokomzimba. Amakhemikhali, i-oxidation, i-hydrolysis, nokuxhumanisa ngokuxhuma okujwayelekile okuguqula ukwakheka kwesakhiwo senjoloba. Lezi zinguquko zingaholela ekuqiniseni, ukuqhekeka, noma ukulahleka kokuqina. Ngokomzimba, izinto ezibonakalayo zingakhombisa ukonakala komhlaba, ukuguquguquka, futhi kuncishiswe amandla ashubile. Ukuqonda lezi zinguquko kubalulekile ekubikezeleni isikhathi sokuphila kwemikhiqizo yenjoloba kanye nezinto zokwakha ezimelana nokuguga.

Izici zezemvelo

Izici zezemvelo zidlala indima ebaluleke kakhulu ekugugeleni kwerabha. Ukuchayeka emisebeni ye-ultraviolet (UV), i-Ozone, kanye namazinga okushisa aphezulu asheshisa inqubo yokucekelwa phansi. Imisebe ye-UV yephula amaketanga e-polymer, okuholela ekuqhekekeni komhlaba nasebusweni. I-Ozone, igesi esebenzayo kakhulu, ihlasela izibopho eziphindwe kabili enjoloba, ibangele ukuqhekeka kwakhiwe ngaphansi kwengcindezi. Ukushisa okuphezulu kungandisa le miphumela ngokwandisa izinga lokuphendula kwamakhemikhali. Ukulwa nalezi zinselelo, abakhiqizi bavame ukufaka izitebele kanye nama-antioxidants ekwakhiweni kwenjoloba.

Ukucindezela Kwemishini

Ukucindezelwa kwemishini, okubandakanya ukwelula, ukucindezela, kanye ne-abrasion, kunomthelela ekugugeni kwenjoloba. Imijikelezo yokucindezela ephindaphindwayo ingadala ukukhathala, okuholela ekuqhekekeni okuncane kanye nokwehluleka ekugcineni. Ukuxhumeka phakathi kwengcindezi yemishini nezici zezemvelo, njengokuvezwa kwe-ozone, kusheshe kusheshise ukuguga. Onjiniyela kumele bacabangele lezi zinto lapho behlela izakhi zenjoloba ngezinhlelo ezifunwayo, njengamathayi ezimoto nezimpawu zezimboni.

Amasu wokunciphisa ukuguga kwerabha

Ukukhetha kwezinto ezibonakalayo

Ukukhetha uhlobo lwenjoloba lubalulekile ekunciphiseni imiphumela yokuguga. Amarubli okwenziwayo, anjenge-ethylene propylene dieen monomer (i-epdm) nama-fluoroolastomemers, anikele ngokuqina okuphezulu ezimweni zemvelo ngokuqhathaniswa nerabha yemvelo. Lezi zinto ezisetshenziswayo zivame ukusetshenziswa kuzinhlelo zokusebenza ezidinga ukuqina okuphezulu nokuphikiswa kwamakhemikhali. Ngeminye imininingwane ngokusebenza okuhlukahlukene kwe-EPDM, hlola Okokuhlikihla.

Izithasiselo kanye nokuziqinisa

Kuhlanganisa izithasiselo kanye nokuzigcina kuzakhiwo zenjoloba kungakhulisa kakhulu ukumelana kwabo nokuguga. Ama-antioxidants avimba ukonakaliswa okungama-oxidative ngokuhlanza ama-radicals wamahhala, kanti abaqinisi be-UV bathola imisebe eyingozi. Ama-filler, njenge-carbon emnyama ne-silica, athuthukise izakhiwo zemishini futhi anciphise umthelela wokucindezela kwezemvelo. Lezi izengezo zihambisana nezinhlelo ezithile zokwandisa ukusebenza nokuphila isikhathi eside.

Ukumboza izimbotshana

Ukusebenzisa izimbobo ezivikelayo kungenye isu eliphumelelayo lokunciphisa ukuguga kwerabha. I-Coatings isebenza njengezithiyo ngokumelene nemisebe ye-UV, i-Ozone, kanye nokuvezwa kwamakhemikhali, ukunweba isikhathi sokuphila kwento. Izigqoko ezisekelwe ku-Silicone, ngokwesibonelo, zisetshenziswa kabanzi kwizicelo zezimoto neze-aerospace zokumelana kwazo kwesimo sezulu nokuqina. Lezi zimbozo zizuzisa ikakhulukazi izingxenye zenjoloba ezivezwa ezindaweni ezinokhahlo.

Izifundo zamacala kanye nezicelo

Imboni yezimoto

Imboni yezimoto ithembele kakhulu enjoloba yezakhi ezinjengamathayi, izimpawu zamaphepha kanye nama-hoses. Ama-rubber agugile agugile, njenge-EPDM nama-fluoroolastomers, ajwayele ukuqinisekisa ukuqina nokusebenza. Isibonelo, i-EPDM ithandelwa ukumelana kwayo okuhle kakhulu ekushiseni, i-ozone, kanye nesimo sezulu, okwenza kube kuhle ngezimpawu zezimoto kanye nama-gaskets. Ukuze ufunde kabanzi mayelana nezinhlelo zokusebenza ze-EPDM, vakashela Okokuhlikihla.

Izicelo ze-Aerospace

Emkhakheni we-aerospace, izakhi zenjoloba kufanele zibekezelele izimo ezimbi kakhulu, kufaka phakathi izindlela eziphakeme, ukuguquguquka kokushisa, nokuchayeka ku-ozone. Ama-Fluoroolastomers asetshenziswa kakhulu kulo mkhakha ngenxa yokumelana kwawo okuhlukile kokuguga nokuwohloka kwamakhemikhali. Lezi zinto zokwenziwa zibalulekile ezimpasheni, ama-gaskets, nama-hoses endizeni nase-spacecraft, ukuqinisekisa ukuphepha nokwethembeka.

Imishini yezimboni

IRubber yinto ebucayi ebalulekile emishini yezimboni, lapho isetshenziselwa khona amabhande, ama-hoses, kanye nokukhanyisa okudlidliza. Inqubo yokuguga ingabeka engcupheni ukusebenza kwalezi zinto, okuholela ekuhlulekeni kwemishini kanye nesikhathi sokuphumula. Ngokukhetha ukuhlukunyezwa okugulayo okuvimbela kanye nokufaka izindlela zokuvikela, abakhiqizi bangathuthukisa ukuthembeka kanye nokusebenza kahle kwemishini yezimboni.

Ukugcina

Inqubo yokuguga yeRubber yinto eyinkimbinkimbi ethonywe yizici zamakhemikhali, zomzimba, kanye nezemvelo. Ukuqonda lezi zinqubo kubalulekile ekuthuthukiseni amasu okuthuthukisa ukuqina kokusebenza nokusebenza. Ngokukhetha izinto ezifanele, okufaka izithasiselo, nokusebenzisa izimbobo zokuvikela, abakhiqizi banganciphisa imiphumela yokuguga futhi banwebe isikhathi sokuphila kwemikhiqizo yenjoloba. Ukuthola eminye imininingwane ngezakhiwo zenjoloba kanye nezicelo, hlola Okokuhlikihla.
