Rubber ke sesebelisoa se feto-fetohang se sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa likoloi, tsa kaho, tsa bophelo bo botle le thepa ea bareki. Lintho tse ikhethang tsa eona, tse kang elasticity, durability, le ho hanyetsa mocheso o feteletseng, li etsa hore e be karolo ea bohlokoa lits'ebetsong tse ngata. Leha ho le joalo, ho khetha mofuta o nepahetseng oa rabara bakeng sa morero o itseng e ka ba mosebetsi o boima ka lebaka la mefuta e sa tšoaneng ea khetho e teng. Sehlooho sena se ikemiselitse ho fana ka tataiso e pharaletseng ea ho khetha rabara e nepahetseng bakeng sa morero o itseng, ho nahanoa ka lintlha tse kang litlhoko tsa kopo, maemo a tikoloho, le ho boloka litšenyehelo. Bakeng sa kutloisiso e tebileng ea lits'ebetso tse fapaneng tsa rabara, etela Rabara.
Ho utloisisa Mefuta ea Rubber
Rabara ea Tlhaho
Rabara ea tlhaho, e nkiloeng ho latex ea lifate tsa rabara, e tsebahala ka ho otloloha ha eona ho babatsehang, matla a eona a ho tsieleha, le ho se khone ho senya. E sebelisoa hangata lits'ebetsong tse kang lithaere, lieta le mabanta a indasteri. Leha ho le joalo, rabara ea tlhaho e na le moo e haelloang teng, ho akarelletsa le ho se khone ho mamella mocheso, ozone le oli, e leng ho etsang hore e se ke ea tšoanela libaka tse itseng.
Rabara ea maiketsetso
Rabara ea maiketsetso e kenyelletsa mefuta e fapaneng ea mefuta, e 'ngoe le e' ngoe e na le thepa e ikhethang e etselitsoeng lits'ebetso tse ikhethileng. E meng ea mefuta e tsebahalang haholo e kenyelletsa:
Styrene-Butadiene Rubber (SBR): E sebelisoa haholo lithaereng tsa likoloi le mabanta a conveyor ka lebaka la ho hanyetsa ha eona ho hoholo le ho boloka chelete e ngata.
Ethylene Propylene Diene Monomer (EPDM): E tsebahala ka ho hanyetsa maemo a leholimo, ozone le mahlaseli a kotsi a UV, e leng se etsang hore e be e loketseng bakeng sa ho rulela le ho sebetsa ka ntle.
Fluoroelastomers (FKM): E hanyetsana haholo le lik'hemik'hale, mocheso le oli, tse sebelisoang hangata sebakeng sa sefofane le litiiso tsa likoloi.
Chloroprene Rubber (CR): E fana ka boemo ba leholimo bo botle le ho hanyetsa ozone, tse loketseng li-gaskets le li-hoses.
Lintlha Tseo U Lokelang ho li Nahana ha U Khetha Rabara
Litlhoko tsa Kopo
Sesebelisoa se reretsoeng ke ntlha ea bohlokoa ho khetha rabara e nepahetseng. Mohlala, lithaere tsa likoloi li hloka lisebelisoa tse nang le khanyetso e phahameng ea abrasion le nako e telele, athe lisebelisoa tsa bongaka li ka etelletsa pele ho lumellana le maemo le maemo. Ho utloisisa litlhoko tse khethehileng tsa morero oa hau ho tla thusa ho fokotsa likhetho.
Maemo a Tikoloho
Mabaka a tikoloho joalo ka mocheso, mongobo, le ho pepesetsoa lik'hemik'hale kapa mahlaseli a UV a ama ts'ebetso ea rabara haholo. Mohlala, EPDM e loketse lits'ebetso tsa kantle ka lebaka la ho hanyetsa boemo ba leholimo bo botle, athe FKM e loketse hantle bakeng sa tikoloho e nang le ts'ebeliso e phahameng ea lik'hemik'hale.
Litšenyehelo
Mathata a lichelete hangata a phetha karolo ea bohlokoa khethong ea thepa. Le hoja rabara ea tlhaho hangata e le theko e tlaase, liraba tsa maiketsetso tse kang FKM le silicone li fana ka ts'ebetso e phahameng ka ho fetisisa lits'ebetsong tse khethehileng, li lokafatsa litšenyehelo tsa tsona tse phahameng.
Lintho tse ncha ho Theknoloji ea Rubber
Rabara e tsitsitseng
Indasteri e ntse e shebana haholo le litloaelo tse tšoarellang, joalo ka ho etsa liraba tse thehiloeng ho bioloji le ho tsosolosa lisebelisoa tse sebelisitsoeng. Litlhahiso tsena li ikemiselitse ho fokotsa tšusumetso ea tikoloho ea tlhahiso ea rabara le ho lahla.
Mekhoa e tsoetseng pele ea ho kopanya
Mekhoa ea morao-rao ea ho kopanya e lumella ho itloaetsa ha thepa ea rabara ho finyella litlhoko tse khethehileng. Ka mohlala, ho kenya li-fillers tse kang carbon black ho matlafatsa nako e telele, ha li-plasticizers li ntlafatsa ho fetoha habonolo.
Qetello
Ho khetha rabara e nepahetseng bakeng sa morero o itseng ho kenyelletsa kutloisiso e phethahetseng ea thepa ea thepa, litlhoko tsa kopo, le maemo a tikoloho. Ka ho nahana ka lintlha tsena, o ka netefatsa ts'ebetso e nepahetseng le ho boloka litšenyehelo. Bakeng sa lintlha tse ling mabapi le lisebelisoa tsa rabara le tharollo, hlahloba Rabara.
