Njengomkhiqizo wenjoloba yophawu lwendabuko, indandatho yokuvala irabha idinga ukuba nokunwebeka okuhle, amandla, ukumelana nokugqokwa okuphezulu, amandla aqinile kanye nobude ngesikhathi sekhefu.Lezi zinkomba zinezidingo eziphezulu futhi zingasetshenziswa ukukhiqiza izimpawu zenjoloba ezisebenza ezindaweni ezingenawo uwoyela nezingagqwali ukusuka ku -20°C kuya ku-100°C.Phakathi kwabo, ukumelana nokugqoka kuthinta ngqo impilo yesevisi yendandatho yokuvala kanye nomphumela wokuvala.Ngakho-ke ungaqhubeka kanjani nokuthuthukisa ukumelana nokugqokwa kwendandatho yokuvala irabha ekukhiqizeni kwangempela?
1. Khulisa ngokufanelekile ubulukhuni benjoloba
Ngokombono, ukwandisa ubulukhuni berabha kungathuthukisa ukumelana kwerabha ekugugekeni.Indandatho yokuvala irabha kanye nendawo yokuxhumana ingaxhunyaniswa ngokulinganayo ngaphansi kwesenzo sokucindezeleka, ngaleyo ndlela ithuthukise ukumelana nokugqoka.Ngokuvamile, abakhiqizi abaningi bendandatho yokuvala irabha ngokuvamile bakhulisa okuqukethwe kwesibabule noma bengeze inani elithile le-ejenti yamandla ukuze kuthuthukiswe ubulukhuni berabha.
Kumele kuqashelwe ukuthi ukuqina kwendandatho yokuvala irabha akufanele kube phezulu kakhulu, ngaphandle kwalokho kuzothinta ukunwebeka kanye nomphumela we-cushioning wendandatho yokufaka uphawu, futhi ekugcineni kuholele ekunciphiseni ukumelana nokugqoka.
2. Lungisa ukunwebeka kwenjoloba
Ukuze kuncishiswe izindleko zemikhiqizo yenjoloba, abakhiqizi bemikhiqizo yenjoloba bazogcwalisa inani elikhulu le-rubber filler, kodwa ukugcwalisa irabha ngokweqile kuzonciphisa ukunwebeka kwenjoloba.Kuyadingeka ukulawula umthamo ngokunengqondo, ukhuphule kahle ukunwebeka kwenjoloba, unciphise i-viscosity kanye ne-hysteresis yerabha, futhi unciphise i-coefficient of friction ukuze kuthuthukiswe ukumelana nokugqokwa kwezimpawu zenjoloba.
3. Lungisa izinga le-vulcanization
Ngokwezici zokusebenza kwe-rubber vulcanization, abakhiqizi bemikhiqizo yenjoloba balungisa ngokunengqondo uhlelo lwe-vulcanization kanye nemingcele ye-vulcanization yezimpawu zenjoloba ukwandisa izinga lokuvuvukala kanye nokwenza ngcono ukumelana nokugqokwa kwezimpawu zenjoloba.
4. Thuthukisa amandla aqinile enjoloba
Lapho irabha isetshenziselwa ukwenza izindandatho zokuvala zenjoloba, ukusetshenziswa kwezigcwalisi zenjoloba eziyizinhlayiyana ezinhle ekubunjweni kungakhuphula amandla e-intermolecular ngokuthuthukisa amandla okudonsa kanye nokucindezeleka okuqinile kwerabha, futhi ngezinga elithile kuthuthukisa ukumelana nokugqokwa kwerabha.
5. Yehlisa i-surface friction coefficient yendandatho yokuvala irabha
Ukwengeza izinto ezifana ne-molybdenum disulfide kanye nenani elincane le-graphite kufomula yendandatho yokuvala iraba kunganciphisa i-coefficient yokungqubuzana okungaphezulu kwendandatho yokuvala irabha futhi kuthuthukise ukumelana nokugqokwa kwendandatho yokuvala.Lapho abakhiqizi bemikhiqizo yenjoloba besebenzisa irabha ukwenza izindandatho zokuvala zenjoloba, bangasebenzisa irabha egaywe kabusha ukuze banciphise izindleko zempahla eluhlaza yemikhiqizo yenjoloba futhi bagweme inkinga yamandla emishini kanye nokumelana nokugqoka kwerabha okubangelwa izigcwalisi zenjoloba ngokweqile.Idizayini enengqondo yefomula yendandatho yokuvala uphawu yenjoloba, ukulungiswa okufanele kwemingcele yenqubo ye-vulcanization, nokukhethwa kwezinto ezisetshenziswayo ezifanele nezinhle kakhulu zenjoloba akukwazi ukunciphisa kuphela izindleko zendandatho yokuvala indandatho yenjoloba, kodwa futhi kuthuthukise ukumelana nokugqokwa kwezindandatho zokuvala irabha.
