Boemo ba Seponche le Likarolo Tse Foamed: Tharollo ea ho qetela e nang le Anti-lerata, Emelanang le Boemo ba leholimo EPR Raw Rubber
Selelekela
Ho latela pono ea litsebi tsa rabara, rabara e thibelang lerata, e hanyetsanang le boemo ba leholimo ea ethylene propylene rabara—EPR e tala rabara—e fana ka tharollo e molemohali bakeng sa lisebelisoa tsa tiiso, haholo-holo likarolong tse nang le foam ea seponche. Rabara ena e na le viscosity e phahameng ea Mooney, litaba tse phahameng tsa ENB, lebelo la ho folisa ka potlako, le lisebelisoa tse phahameng tsa mochine tse netefatsang ts'ebetso ea nako e telele le ho tšoarella.
High Mooney Viscosity
EPR rabara e tala e bonts'a viscosity e phahameng ea Mooney, e netefatsang ts'ebetso e ntle le thepa ea ho bopa. Viscosity ena e fana ka boiketlo ba ho sebetsana le ho qhekella nakong ea tlhahiso, ho netefatsa ho ikatisa le ho tsitsisa tlhahiso. Viscosity e phahameng e boetse e kenya letsoho ntlafatsong ea ts'ebetso ea ho tiisa, e etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng tsa tiiso.
High ENB Content
EPR rabara e tala e na le palo e phahameng ea ENB (ethylene-propylene-butylene), e tlatsetsang ho thepa ea eona e ikhethang. ENB e eketsa ho tenyetseha le ho tiea ho rabara, e ntlafatsa thepa ea eona ea mochini. Likahare tse phahameng tsa ENB li boetse li etsa hore rabara e se ke ea mamella boemo ba leholimo, e netefatsa bophelo bo bolelele lits'ebetsong tsa kantle.
Fast Curing Speed
EPR rabara e tala e na le lebelo la ho folisa ka potlako, ho bolelang hore e ka sebetsoa kapele ntle le boleng ba sehlabelo. Lebelo la ho folisa ka potlako le thusa bahlahisi ho fihlela linako tse khutšoane tsa potoloho, ho ntlafatsa tlhahiso, le ho fokotsa litšenyehelo tsa tlhahiso. Ho feta moo, lebelo la ho folisa rabara ka potlako le tiisa tiiso e tiileng le e tšepahalang ha e kengoa.
High Mechanical Properties
EPR rabara e tala e bonts'a thepa e phahameng ea mochini, ho kenyelletsa le matla a thata, modulus le boima. Thepa ena e netefatsa hore rabara e loketse lits'ebetso tse fapaneng tsa ho tiisa moo ho hlokahalang litiiso tse matla le tse tšoarellang. Thepa ea mochini ea rabara e tala ea EPR e e etsa khetho e ntle bakeng sa lits'ebetso tsa tiiso profilong ea seponche le likarolo tse foamed.
Ka Kakaretso
EPR rabara e tala ea Mooney viscosity e phahameng, litaba tse phahameng tsa ENB, lebelo la ho folisa ka potlako, le lisebelisoa tse phahameng tsa mochini li etsa hore e be thepa e loketseng bakeng sa lits'ebetso tsa tiiso profaeleng ea seponche le likarolo tse foamed. Ts'ebetso e ntle ea ho tiisa ha rabara le ho hanyetsa boemo ba leholimo ho netefatsa ts'ebetso ea nako e telele le ho tšoarella lits'ebetsong tse fapaneng tsa ho tiisa. Lebelo la ho phekola ka potlako le thusa bahlahisi ho finyella linako tse khutšoanyane tsa potoloho le ho ntlafatsa tlhahiso, ho fokotsa litšenyehelo tsa tlhahiso ha ba ntse ba boloka boleng. Lisebelisoa tsa mechine li netefatsa hore rabara e loketse mekhoa e sa tšoaneng ea ho tiisa moo ho hlokahalang litiiso tse matla le tse tšoarellang. Boemo ba seponche le likarolo tse foamed tse nang le rabara e tala ea EPR li fana ka tharollo ea mantlha ea ho tiisa lits'ebetso tse hlokang ho hanyetsa lerata le boemo ba leholimo.
