Mica Flakes Ho Fetola Indasteri ea Rubber Tataiso e Felletseng ea Batlatsi ba Ts'ebetso e Phahameng

Tlhaloso e Khutšoanyane:

Li-flakes tsa Mica, ka sebopeho sa tsona se ikhethang sa lamellar, botsitso bo ikhethang ba lik'hemik'hale, le ho lumellana ho tsotehang le matrices ea rabara, li ipakile ka tieo e le li-filler tse sebetsang hantle indastering ea rabara. Ho fapana le li-filler tse tloaelehileng tse kang carbon black kapa calcium carbonate, li-flakes tsa mica li fana ka motsoako o ikhethang oa matlafatso ea mechini, ho hanyetsa boemo ba leholimo, le botsitso ba litekanyo, e leng se etsang hore e be khetho e ntle bakeng sa lihlahisoa tsa rabara tse sebetsang libakeng tse thata, ho kenyeletsoa le litiiso tsa likoloi, liphaephe tsa rabara tsa indasteri le mabanta a tsamaisang thepa.

Sebakeng sa litiiso tsa rabara tsa likoloi, ho kenyeletsoa litiiso tsa mamati, litiiso tsa lifensetere le li-gasket tsa enjene, li-flakes tsa mica li bapala karolo ea bohlokoa ho ntlafatseng ho hanyetsa ho taboha le ts'ebetso ea sete ea khatello. Litiiso tsena li pepesehela khatello ea mechine khafetsa, ho feto-fetoha ho feteletseng ha mocheso ho tloha ho -40°C ho isa ho 120°C, le ho pepesehela mahlaseli a UV nako e telele, e leng mabaka a ka etsang hore litiiso tse tloaelehileng tsa rabara li petsohe, li tiee, kapa li lahleheloe ke ho tenyetseha ha nako e ntse e ea.

Ho eketsoa ha 8%-15% ea li-flakes tsa mica tse nang le tekanyo e phahameng ea aspect ratio, tse nang le boholo ba likaroloana tsa 30-80 μm le aspect ratio ea ≥100, ho rabara ea ethylene-propylene-diene monomer (EPDM) ho hlahisa liphetho tse tsotehang. Matla a ho taboha ha rabara a eketseha ka 40%-60%, ha sekhahla sa khatello, se lekantsoeng kamora lihora tse 70 ho 100°C, se theoha haholo ho tloha ho 35% ho isa ho 15%. Moetsi ea ka sehloohong oa likarolo tsa likoloi Jeremane o entse liteko tse pharaletseng a sebelisa li-flakes tsa rona tsa mica litiisong tsa mamati a EPDM. Liphetho li bile tse makatsang: litiiso li ile tsa boloka ho tenyetseha ha tsona le ts'ebetso ea tsona ea ho koala bakeng sa lipotoloho tse 500,000 tsa ho bula le ho koala, ha li bapisoa le lipotoloho tse 300,000 feela bakeng sa litiiso tse se nang li-flakes tsa mica. Bophelo bona bo atolositsoeng ba ts'ebeletso ha bo fokotse feela litšenyehelo tsa tlhokomelo bakeng sa beng ba likoloi empa hape bo ntlafatsa ts'epo e akaretsang ea lihlahisoa tsa likoloi.

Bakeng sa liphaephe tsa rabara tsa indasteri tse sebelisoang phetisong ea lik'hemik'hale, oli le metsi, li-flakes tsa mica li bohlokoa haholo ho ntlafatseng khanyetso ea lik'hemik'hale le khanyetso ea khatello. Liphaephe tsena hangata li kopana le mecha ea phatlalatso e senyang 'me li tlameha ho mamella khatello e phahameng ea ka hare ea ho fihla ho 10 MPa. Li-flakes tsa Mica, ka sebopeho sa tsona sa lamellar se sa keneng, li etsa mokoallo o sebetsang ka har'a matrix ea rabara, li fokotsa ho kenella ha lik'hemik'hale ka 50%-70%.

Ha li eketsoa liphaepheng tsa rabara ea nitrile (NBR) ka tekanyo ea 10%-20%, li-flakes tsa mica li eketsa khatello e phatlohileng ea phaephe ka 25%-35% 'me li eketsa bophelo ba eona ba ts'ebeletso lits'ebetsong tsa phetisetso ea oli ho tloha selemong se le seng ho isa ho lilemo tse 2-3. Setsi sa lik'hemik'hale Netherlands se ile sa beha liphaephe tsa rona tsa NBR tse matlafalitsoeng ke mica tekong ea phetisetso ea 20% ea sulfuric acid e kopaneng. Liphetho li bile tse felletseng: kamora likhoeli tse 12 tsa ts'ebeliso e tsoelang pele, liphaephe ha lia ka tsa bontša matšoao a ho ruruha kapa ho lutla, athe liphaephe tse tloaelehileng tsa NBR li ile tsa hloleha kamora likhoeli tse 4 feela. Ho feta moo, li-flakes tsa mica li ntlafatsa botsitso ba boholo ba liphaephe tsa rabara, li fokotsa ho fokotseha nakong ea vulcanization ka 15%-25% le ho netefatsa hore li lumellana hantle le lihokelo.

Li-flakes tsohle tsa rona tsa mica li fihlela maemo a thata a indasteri mabapi le matšoao a bohlokoa a tekheniki. Mongobo ke ≤0.3%, molora ke ≤0.5%, ho monngoa ha oli ke ≤25 mL/100g, 'me li bontša ho hanyetsa mocheso hantle, li lula li tsitsitse mochesong o fihlang ho 600°C. Ho feta moo, lihlahisoa tsa rona li latela ka botlalo melaoana ea RoHS le REACH, ka metale e boima e ka tlase ho meeli ea polokeho ea lefats'e (lead ≤0.0005%, arsenic ≤0.0003%).

Ha ho tluoa tabeng ea thepa, re beha boleng le botšepehi ba lihlahisoa tsa rona pele. Li-flakes tsa rona tsa mica li pakiloe ka mekotleng e sa keneleng mongobo (25 kg/mokotla), e nang le filimi ea polyethylene e ka hare le mokotlana oa pampiri oa kraft o ka ntle ho thibela ho monngoa ha mongobo nakong ea lipalangoang tsa leoatleng. Re thehile likamano tse matla le lik'hamphani tse etellang pele tsa likepe tse kang Maersk le COSCO, re netefatsa hore li tlisoa ka nako ho bareki Europe, Amerika Leboea le Asia Boroa-bochabela matsatsing a 15-30.

Ke aluminosilicate ya potassium, aluminium, magnesium, tšepe, lithium le dimethale tse ding, tseo kaofela di nang le mealo le monoclinic. Kristale ke pseudohexagonal lamellae kapa plate jwalo ka, ka nako e nngwe columnar. Lekhalo la lamellar le feletse haholo, ka kganya ya khalase le lakane e tenyetsehang. Index ya refractive ya mica e eketseha ka keketseho ya dikahare tsa tshepe, ho tloha ho protrusion e tlase ho ya ho protrusion e mahareng. Mofuta o se nang tshepe ha o na mmala ka hara flake. Ha dikahare tsa tshepe di le hodimo, mmala o lefifi le ho feta, mme o na le polychromatic le monyelo o eketsehileng.
