Rabara ea polyurethane, elastomer e feto-fetohang e koalang lekhalo lipakeng tsa rabara le polasetiki, e fetohile lejoe la motheo liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang. E tsebahala ka matla a eona a phahameng, elasticity, le ho hana ho taboha le ho taboha, rabara ea polyurethane e sebelisoa haholo makaleng a kang a likoloi, a kaho le a tlhahiso. Bokhoni ba eona ba ho ikamahanya le lits'ebetso tse fapaneng bo e etsa khetho e ratoang ho baenjiniere le baqapi ba bangata. Mohlala, khanyetso ea eona e phahameng ea abrasion, e ka bang makhetlo a 10 ho feta lisebelisoa tse ling, e entse hore e be ea bohlokoa haholo libakeng tse nang le khatello e phahameng ea maikutlo. Ho hlahloba lisebelisoa le melemo ea rabara ea polyurethane, o ka sheba lintlha tse qaqileng tse fanoeng tlas'a sehlooho. Rubber ea polyurethane.
Thepa ea Polyurethane Rubber
Ho tšoarella le ho thatafala
E 'ngoe ea likarolo tse hlahelletseng tsa rabara ea polyurethane ke ho tšoarella ha eona ho makatsang. E fana ka mefuta e mengata ea maemo a thata, ho tloha tlase ho 20 Shore A ho ea holimo ho 80 Shore A, e etsa hore e tšoanelehe bakeng sa lisebelisoa tse fapaneng. Ho feto-fetoha ha maemo ana ho thatafalloa ho finyelloa ka mekhoa e fapaneng, e lumellang bahlahisi ho fetola thepa ho ea ka litlhoko tse itseng. Mohlala, litlolo tse bonolo li loketse lits'ebetso tsa cushion, athe mefuta e thata haholo e sebelisoa ho lirolara le litiiso tsa indasteri.
Abrasion Resistance
Rabara ea polyurethane e ipabola ka ho hanyetsa abrasion, e feta lisebelisoa tse ngata tsa setso. Khanyetso ea eona ea ho roala e phahame ka makhetlo a 5 ho isa ho a 10 ho feta ea rabara ea tlhaho kapa li-rabara tse ling tsa maiketsetso. Thepa ena e e etsa khetho e ntle bakeng sa lits'ebetso tse joalo ka mabanta a conveyor, gaskets le mabili, moo likhohlano le ho roala ho sa feleng ho ke keng ha qojoa.
Matla a Matla a Phahameng
Matla a tsitsitseng a rabara ea polyurethane a ka fihla ho 600 kgf/cm², e leng e phahameng haholo ho feta ea li-elastomer tse ling tse ngata. Matla ana a phahameng a etsa bonnete ba hore thepa e ka mamella meroalo e boima le khatello ea maikutlo ntle le ho holofala kapa ho robeha, e leng se etsang hore e be se loketseng bakeng sa ho batla lits'ebetso tsa indasteri.
Elasticity le Low Residual Deformation
Rabara ea polyurethane e bonts'a elasticity e ntle haholo, e bolelele bo fihlang ho 600%. Leha e le tlas'a bolelele bo phahameng joalo, deformation e setseng e nyane, hangata e tloha ho 2% ho isa ho 4%. Thepa ena e bohlokoa bakeng sa lits'ebetso tse hlokang ho otlolloa khafetsa le ho hatella, joalo ka liqibi le li-diaphragm.
Ho hanyetsa Oli le Lik'hemik'hale
Molemo o mong oa bohlokoa oa rabara ea polyurethane ke ho hanyetsa ha eona oli le lik'hemik'hale. E feta rabara ea nitrile ho hanyetsa oli ea liminerale 'me e sebetsa ka makhetlo a 5 ho isa ho a 6 ho feta rabara ea tlhaho. Sena se etsa hore e be sesebelisoa se ratoang bakeng sa ho sebelisoa libakeng tse pepesehileng oli, mafura le lik'hemik'hale tse ling tse thata.
Lisebelisoa tsa Rabara ea Polyurethane
Indasteri ea Likoloi
Lefapheng la likoloi, rabara ea polyurethane e sebelisoa haholo ho etsa lihlahla tse emisitsoeng, litiiso le likhase. Bokhoni ba eona bo phahameng ba ho jara le ho hanyetsa ho roala bo etsa hore e be e loketseng bakeng sa lits'ebetso tsena. Ho feta moo, bokhoni ba eona ba ho mamella mocheso o feteletseng bo tiisa ts'ebetso e tšepahalang maemong a leholimo a chesang le a batang.
Kaho le Lisebelisoa
Rabara ea polyurethane e sebelisoa haholo kahong bakeng sa lits'ebetso tse joalo ka li-vibration dampers, flooring le coatings. Ho tšoarella ha eona le ho hanyetsa ho senya le lik'hemik'hale ho etsa hore e be khetho e ka tšeptjoang bakeng sa libaka tse thata tsa kaho. Ho feta moo, ho feto-fetoha ha eona ho e lumella ho monya litšisinyeho le ho thothomela ka katleho, ho ntlafatsa bophelo bo bolelele ba meaho.
Lisebelisoa tsa Tlhahiso le Liindasteri
Ha ho etsoa, rabara ea polyurethane e sebelisoa mabanta a conveyor, lirolara le likarolo tsa mochini. Matla a eona a phahameng le ho hanyetsa ho apara ho tiisa hore likarolo tsena li ka sebetsana le meroalo e boima le ts'ebetso e tsoelang pele ntle le ho nkeloa sebaka khafetsa. Sena ha se fokotse nako ea ho theoha feela empa hape se fokotsa litšenyehelo tsa tlhokomelo.
Thepa ea bareki
Rabara ea polyurethane e boetse e fumanoa thepa e fapaneng ea bareki, ho kenyelletsa lieta, lisebelisoa tsa lipapali le thepa ea lapeng. Sebopeho sa eona se bobebe, se kopantsoeng le ho tšoarella ha sona le ho feto-fetoha ha maemo, se etsa hore e be khetho e ratoang bakeng sa likopo tsena. Ka mohlala, e sebelisoa litulong tsa lieta tsa liatleletiki tse sebetsang hantle ho fana ka li-cushion le tšehetso.
Qetello
Rabara ea polyurethane e hlahella e le lisebelisoa tse tenyetsehang le tse tšepahalang tse fihlelang litlhoko tsa liindasteri tse fapaneng. Motsoako oa eona o ikhethang oa thepa, ho kenyeletsoa matla a phahameng, elasticity, le ho hanyetsa ho apara le lik'hemik'hale, e etsa hore e be khetho e ratoang bakeng sa lits'ebetso ho tloha ho likoloi ho ea ho thepa ea bareki. Bakeng sa kutloisiso e tebileng ea litšebeliso le melemo ea eona, o ka hlahloba ho eketsehileng ka Rubber ea polyurethane.
