Rubber Molding Ente Molding bakeng sa Lihlahisoa tsa Rubber

Compression Molding

Ha ho etsoa compression, motsoako oa rabara o kenngoa ka har'a mokoti oa hlobo, 'me khatello e sebelisoa ho hatella thepa hore e be sebopeho se lakatsehang. Joale mocheso o sebelisoa ho phekola rabara. Mokhoa ona o sebelisoa hangata ho etsa lihlahisoa tse kang li-gaskets, litiiso le likarolo tsa koloi.

Ho Bopa ka Ente

Ho etsa ente ho kenyelletsa ho kenya rabara e qhibilihisitsoeng ka har'a hlobo e tlas'a khatello e matla. Ts'ebetso ena e nepahetse bakeng sa ho etsa likarolo tse rarahaneng le tse nepahetseng, ho kenyeletsoa likarolo tsa koloi le thepa ea bareki. Overmolding le ho kenya ho bōptjoa ke mefuta e fapaneng ea ts'ebetso ena, e kenyelletsang ho kopanngoa ha likarolo tsa tšepe tse phethiloeng ka har'a mokoti oa hlobo pele o kenya rabara.

Ho fetisoa Moulding

Ho kopanya likarolo tsa ho hatella le ho etsa ente, ho bopa ho fetisa ho sebelisa tekanyo e lekantsoeng ea rabara ka kamoreng e futhumetseng. Plunger e qobella thepa hore e be mokoti oa hlobo, e etsa hore e tšoanelehe bakeng sa ho hlahisa likhokahanyo tsa motlakase, li-grommets le likarolo tse nyane tse nepahetseng.

Extrusion

Extrusion e sebelisoa ho theha bolelele bo tsoelang pele ba rabara e nang le libopeho tse fapaneng tse fapaneng, joalo ka li-hoses, li-tubing le li-profiles. Rabara e qobelloa ka lefu ho finyella tlhophiso e lakatsehang.

Ho phekola (Vulcanization)

Ho phekola, kapa vulcanization, ho kenyelletsa ho hokahanya liketane tsa polymer ea rabara ho matlafatsa matla, elasticity le ho hanyetsa mocheso. Sena se finyelloa ka ho sebelisa mocheso le khatello ho sehlahisoa sa rabara se bōpiloeng, ka mekhoa e tloaelehileng e kenyeletsang mouoane, moea o chesang, le phekolo ea microwave.

Rubber ho Metal Bonding

Ts'ebetso e khethehileng, ho kopanya rabara ho tšepe ho etsa lihlahisoa tse kopanyang ho feto-fetoha ha rabara le matla a tšepe. Karolo ea rabara e entsoe esale pele kapa e bōptjoa, e behoa holim'a tšepe ka sekhomaretsi, ebe e kenngoa mocheso le khatello bakeng sa vulcanization kapa ho phekola. Ts'ebetso ena e tlama rabara le tšepe ka lik'hemik'hale, e etsa hore ho be le khokahanyo e tiileng le e tšoarellang ea bohlokoa bakeng sa lits'ebetso tse hlokang ho thothomela le ho ts'ehetsa sebopeho.

Ho kopanya

Ho kopanya ho kenyelletsa ho kopanya lisebelisoa tsa rabara tse tala le li-additives tse fapaneng ho etsa motsoako oa rabara o nang le thepa e khethehileng. Li-additives li ka kenyelletsa lisebelisoa tsa ho folisa, li-accelerator, li-antioxidants, li-filler, li-plasticizers le li-colorants. Ho kopanya hona hangata ho etsoa ka leloala la li-roll tse peli kapa motsoako o ka hare ho etsa bonnete ba kabo e tšoanang ea li-additives.

Milling

Ka mor'a ho kopanya, motsoako oa rabara o kena lits'ebetsong tsa ho sila kapa ho kopanya ho tsoela pele ho homogenize le ho bōpa thepa. Mohato ona o tlosa li-bubble tsa moea 'me o tiisa ho tšoana ho motsoako.

Kamora ho sebetsa

Ka mor'a ho phekoloa, sehlahisoa sa rabara se ka 'na sa e-ba le mekhoa e meng, ho kenyelletsa le ho kuta, ho senya (ho tlosa lintho tse feteletseng), le ho phekola ka holim'a metsi (joaloka ho roala kapa ho bentša) ho finyella litlhoko tse khethehileng.

Rabara ea Tlhaho (NR):

E tsoa ho lero la latex la sefate sa rabara (Hevea brasiliensis), rabara ea tlhaho e tsebahala ka ho phutholoha ho phahameng le ho tiea. E sebelisoa hangata lits'ebetsong tse kang lithaere, lieta le lihlahisoa tsa bareki, e na le khanyetso e fokolang mochesong le lik'hemik'hale.

Rabara ea maiketsetso:

E entsoe ka maiketsetso ka mekhoa ea lik'hemik'hale, li-rabara tsa maiketsetso li fana ka mefuta e mengata ea thepa. Mefuta e meng e tloaelehileng e kenyelletsa:

Styrene-Butadiene Rubber (SBR)

E sebelisoa haholo bakeng sa khanyetso e ntle ea abrasion le ho tšoarella, hangata e fumanoang lithaereng tsa koloi le mabanta a conveyor.

Polybutadiene Rubber (BR):

E bohlokoa bakeng sa ho mamella maemo a holimo le ho feto-fetoha ha maemo a mocheso a tlase, hangata e sebelisoang ha ho etsoa lithaere le joalo ka ntho e fetolang tšusumetso lipolasetiki.

Nitrile Rubber (NBR):

E bonts'a khanyetso e ikhethang ea oli, mafura le lik'hemik'hale, e etsa hore e tšoanelehe bakeng sa liqibi, li-gaskets le li-O-rings makaleng a likoloi le a indasteri.

Butyl Rubber (IIR):

E tsebahala ka ho se kenele likhase, e loketseng lithaere tse ka hare tsa thaere, lilaene tse ka hare bakeng sa litanka tsa polokelo ea lik'hemik'hale, le litšitiso tsa meriana.

Neoprene (CR):

E fana ka khanyetso e ntle ea boemo ba leholimo, ozone le oli, khetho e tsebahalang bakeng sa li-wetsuits, li-hoses le li-gaskets tsa likoloi.

Ethylene Propylene Diene Monomer (EPDM):

E nkoa e le ea bohlokoa bakeng sa ho hanyetsa mocheso, boemo ba leholimo, le mahlaseli a kotsi a UV, hangata a sebelisetsoang thepa ea marulelo, litiiso tsa likoloi le ho kenya motlakase ka ntle.

Rabara ea Silicone (VMQ):

E tsebahala ka ho hanyetsa mocheso o babatsehang le thepa ea ho kenya motlakase, e sebelisoang hangata lisebelisoa tsa bongaka, li-cookware, lisebelisoa tsa likoloi, le joalo ka sealant.

Fluoroelastomers (FKM):

E hanyetsana haholo le lik'hemik'hale, mocheso o phahameng le oli, tse sebelisoang hangata lits'ebetsong tse hlokang khanyetso e ikhethang ea lik'hemik'hale, joalo ka litiiso le li-gasket indastering ea lik'hemik'hale le ea sefofane.

Chloroprene Rubber (CR):

E boetse e tsejoa e le Neoprene, e fana ka khanyetso e ntle ho boemo ba leholimo le ozone. Hangata e sebelisoa lits'ebetsong tse hlokang ho leka-lekana ha thepa ea 'mele, joalo ka liaparo tsa metsi le mabanta a indasteri.

Polyurethane (PU):

Ho kopanya thepa ea rabara le polasetiki, rabara ea polyurethane e ananeloa ka lebaka la ho hanyetsa ha eona le matla a ho jara mojaro. E sebelisoa hangata ho mabili, lihlahla, le likarolo tsa mochini oa indasteri.
