Dị ka ngwaahịa rọba akara ọdịnala, mgbanaka mkpuchi mkpuchi rọba kwesịrị inwe ezigbo ngbanwe, ike, akwa mkpuchi mkpuchi, ike ike na elongation na ezumike.Ihe ngosi ndị a nwere ihe ndị dị elu chọrọ ma nwee ike iji ya mee ihe mkpuchi rọba nke na-arụ ọrụ na gburugburu ebe obibi na-enweghị mmanụ na-emebi emebi site na -20 ° C ruo 100 ° C.N'ime ha, nkwụsi ike na-eyi na-emetụta kpọmkwem ndụ ọrụ nke mgbanaka akara na mmetụta akara.Ya mere, otu esi aga n'ihu melite eyi iguzogide mgbanaka akara roba na mmepụta n'ezie?
1. N'ụzọ kwesịrị ekwesị mụbaa ike roba
Na tiori, ịba ụba ike nke rọba nwere ike ime ka mgbochi rọba na-eguzogide nrụrụ.Enwere ike ịkpọtụrụ mgbanaka mkpuchi roba na elu kọntaktị n'otu n'otu n'okpuru mmetụta nke nrụgide, si otú a na-emeziwanye nguzogide eyi.Ọtụtụ mgbe, ọtụtụ ndị na-emepụta mgbanaka mkpuchi rọba na-abawanye ọdịnaya sọlfọ ma ọ bụ na-agbakwunye ụfọdụ onye na-ahụ maka ike iji meziwanye ike nke rọba ahụ.
Ekwesiri ighota na ike nke mgbanaka mkpuchi roba ekwesịghị ịdị elu, ma ọ bụghị ya, ọ ga-emetụta elasticity na mmechi nke mgbanaka akara, ma mesịa mee ka mbelata na-eguzogide iyi.
2. Gbanwee elasticity roba
Iji belata ọnụ ahịa ngwaahịa rọba, ndị na-emepụta ngwaahịa rọba ga-ejupụta nnukwu ihe mkpuchi rọba, mana oke rọba ga-ebelata ngbanwe nke roba.Ọ dị mkpa iji ezi uche na-achịkwa usoro onunu ogwu, na-abawanye ngbanwe nke rọba nke ọma, belata viscosity na hysteresis nke roba, ma belata ọnụọgụ nke esemokwu iji meziwanye nguzogide mkpuchi nke mkpuchi roba.
3. Gbanwee ogo nke vulcanization
Dị ka njirimara nke arụmọrụ vulcanization rọba si dị, ndị na-emepụta ngwaahịa rọba na-edozi usoro mmeghe na vulcanization paramita nke mkpuchi rọba iji mee ka ogo vulcanization dịkwuo elu ma melite nkwụsị nke mkpuchi rọba.
4. Meziwanye ike ike nke rọba
Mgbe a na-eji rọba mee mgbanaka mkpuchi rọba, iji ezigbo ihe eji eme ihe na-emepụta ihe na-emepụta ihe nwere ike ime ka ike intermolecular dịkwuo elu site na imeziwanye ike ike na nrụgide nke rọba, na ruo n'ókè ụfọdụ na-eme ka nkwụsị nke rọba dịkwuo mma.
5. Belata ọnụọgụ esemokwu elu nke mgbanaka akara roba
Ịgbakwunye ihe ndị dị ka molybdenum disulfide na obere graphite na usoro nke mgbanaka mkpuchi roba nwere ike ibelata ọnụ ọgụgụ esemokwu elu nke mgbanaka mkpuchi roba ma melite nkwụsị nke mgbanaka akara.Mgbe ndị na-emepụta ngwaahịa rọba na-eji rọba mee mgbanaka mkpuchi rọba, ha nwere ike iji rọba emegharịrị iji belata ọnụ ahịa akụrụngwa nke ngwaahịa rọba ma zere nsogbu nke ike igwe ma na-eyi nguzogide nke rọba nke oke rọba na-akpata.Ezi uche imewe nke roba akara mgbanaka mgbanaka usoro, kwesịrị ekwesị ukpụhọde nke vulcanization usoro parameters, na nhọrọ nke kwesịrị ekwesị na magburu onwe roba akụrụngwa nwere ike ọ bụghị nanị ibelata na-eri nke roba akara mgbanaka ngwaọrụ, kamakwa melite eyi iguzogide roba akara yiri mgbaaka.
