Joalo ka sehlahisoa sa setso sa rabara ea tiiso, selikalikoe sa ho tiisa rabara se hloka ho ba le elasticity e ntle, matla, khanyetso e phahameng ea ho roala, matla a thata le bolelele nakong ea khefu.Lipontšo tsena li na le litlhoko tse phahameng 'me li ka sebelisoa ho hlahisa litiiso tsa rabara tse sebetsang libakeng tse se nang oli le tse sa senyeng ho tloha ho -20°C ho ea ho 100°C.Har'a bona, ho hanyetsa ho apara ho ama ka ho toba bophelo ba tšebeletso ea lesale la ho tiisa le phello ea ho tiisa.Joale u ka ntlafatsa joang ho hanyetsa ho roala ha reng ea ho tiisa rabara tlhahisong ea 'nete?
1. Eketsa boima ba rabara ka nepo
Ka khopolo, ho eketsa boima ba rabara ho ka matlafatsa khanyetso ea rabara ho deformation.Lesale la ho tiisa rabara le sebaka sa ho kopana se ka kopanngoa ka tsela e lekanang tlas'a ketso ea khatello ea kelello, kahoo ho ntlafatsa ho hanyetsa ho apara.Hangata, bahlahisi ba bangata ba lesale la ho tiisa rabara hangata ba eketsa bokahare ba sebabole kapa ba eketsa tekanyo e itseng ea matla ho ntlafatsa ho thatafala ha rabara.
Hoa lokela ho hlokomeloa hore boima ba lesale la ho tiisa rabara ha boa lokela ho ba bo phahameng haholo, ho seng joalo bo tla ama phello ea elasticity le cushioning ea lesale la ho tiisa, 'me qetellong le etse hore ho fokotsehe ho apara ho hanyetsa.
2. Fetola elasticity ea rabara
E le ho fokotsa litšenyehelo tsa lihlahisoa tsa rabara, bahlahisi ba lihlahisoa tsa rabara ba tla tlatsa li-filler tse ngata, empa ho tlatsoa ho feteletseng ho tla fokotsa elasticity ea rabara.Hoa hlokahala ho laola litekanyetso ka nepo, ho eketsa elasticity ea rabara, ho fokotsa viscosity le hysteresis ea rabara, le ho fokotsa coefficient ea likhohlano ho ntlafatsa ho hanyetsa ha litiiso tsa rabara.
3. Fetola tekanyo ea vulcanization
Ho ea ka litšoaneleho tsa ts'ebetso ea rabara vulcanization, baetsi ba lihlahisoa tsa rabara ka mokhoa o utloahalang ba fetola sistimi ea vulcanization le liparamente tsa vulcanization tsa litiiso tsa rabara ho eketsa boemo ba vulcanization le ho ntlafatsa ho hanyetsa ha litiiso tsa rabara.
4. Ntlafatsa matla a thata a rabara
Ha rabara e sebelisoa ho etsa mehele ea ho tiisa rabara, tšebeliso ea li-fillers tsa rabara e ntle ha e etsoa e ka eketsa matla a intermolecular ka ho ntlafatsa matla a tsitsipano le khatello ea maikutlo ea rabara, 'me ho isa bohōleng bo itseng ho ntlafatsa ho hanyetsa ha rabara.
5. Fokotsa sekhahla sa khohlano ea holim'a lesale la ho tiisa rabara
Ho eketsa lisebelisoa tse kang molybdenum disulfide le graphite e nyenyane ho mokhoa oa lesale la ho tiisa rabara ho ka fokotsa coefficient ea ho ferekanngoa ha lesale la ho tiisa rabara le ho ntlafatsa ho hanyetsa ha lesale la ho tiisa.Ha baetsi ba lihlahisoa tsa rabara ba sebelisa rabara ho etsa mehele ea ho tiisa rabara, ba ka sebelisa rabara e tsosolositsoeng ho fokotsa litšenyehelo tsa thepa e tala ea lihlahisoa tsa rabara le ho qoba bothata ba matla a mochine le ho roala ho hanyetsa ha rabara ho bakoang ke li-filler tse feteletseng.Moralo o utloahalang oa foromo ea lesale la ho tiisa rabara, tokiso e nepahetseng ea liparamente tsa ts'ebetso ea vulcanization, le khetho ea thepa e tala e loketseng le e ntle haholo e ke ke ea fokotsa feela litšenyehelo tsa thepa e tala ea ho tiisa rabara, empa hape le ho ntlafatsa ho hanyetsa ha mehele ea ho tiisa rabara.
