Tharollo ea bothata bona ke ho khetha rabara e tala e nang le viscosity e ka bang 70, le ho sebelisa rabara e tala e nang le kabo e moqotetsane ea limolek'hule, ebe o eketsa boka ba boka ba Brazil kapa boka ba fluorine kapa polyethylene e tlaase ea limolek'hule ka foromo, e ka boela ea rarolla ketsahalo e khomarelang ea rolara.
Ntlha ea 3. Mabapi le matheba a masoeu ka har'a rabara e kopanyang
Ho ke ke ka lebaka la ho ba bang ba ho hasana phofo ea fluorine rabara compounding moemeli ha e junifomo, kapa ka lebaka la phofo mongobo caking, tse kang acid absorbers khalsiamo hydroxide, magnesium oxide e le diatomaceous lefatšeng, barium sulfate, joalo-joalo, tharollo, ho thibela ho kopanya moemeli mongobo le ho matlafatsa tshesaane feta tshebetso.
Ntlha ea 4. Sehlahisoa se bonolo ho tabola
Lebaka, e ka 'na ea e-ba e teteaneng haholo ea burr, e fokotsang ha e tabola, kapa hlobo e nang le e thata haholo, e tsoa likarolong tsa hlobo ea li-burr li khomaretsoe ka har'a hlobo, e bonolo ho tloha sehlahisoa le burr pele e rusolla, matla a sa tšoaneng ha a qala hlobo, ho bonolo ho tabola sehlahisoa. Ka linako tse ling ho sebetsa ha hlobo ho ba thata, kapa thepa e khomarelang e khomarela hlobo, 'me ha vulcanization e felile, e baka mathata a ho tlosa hlobo le ho tabola sehlahisoa habonolo. Ho phaella moo, mocheso oa vulcanization o phahame haholo, o tla boela o etse hore lihlahisoa li be brittle le ho qhaqha habonolo. Bakeng sa ntho e sa tloaelehang e ka holimo, e ka rarolloa ho tloha likarolong tse latelang: ho nepahala ha hlobo ho lokela ho ba hantle ho hlaka ha sekhahla Ra ka tlaase ho 0.8, lekhalo le loketseng ha lea lokela ho ba le leholo haholo, taolo ea mocheso oa vulcanization e setseng pakeng tsa likhato tse 170 e ntle, 'me boima ba rabara bo lokela ho ba bo nepahetseng.
Ntlha ea 5. ho fokotseha le ho phunyeha Bothata ba
Ke ka lebaka la khatello e tlosoa ha hlobo e buloa, shrinkage ea rabara ea fluorine, 'me karolo ea burr e khomaretsoe ka har'a hlobo e nang le bokaholimo bo pakeng, kahoo pakeng tsa karolo ea sehlahisoa le burr e hlahisa matla a thata, e le hore sehlahisoa le burr li arohane, ha sekhahla sa marang-rang se atolosoa ho karolo ea sehlahisoa, se etsa hore ho fokotsehe le ho phunyeha ketsahalo. Tharollo ke ho fokotsa mocheso oa vulcanization ka mokhoa o nepahetseng, khetha Viscosity ea Menny hoo e ka bang 70 [ML1 + 4] 121 degrees, ha mold fit degree e lokela ho ba e loketseng, eseng e hlephileng le e thata haholo.
Ntlha ea 6. Moeli o tšoana le ho chesa
Ke mocheso oa vulcanization o phahame haholo, haholo-holo lihlahisoa tse teteaneng, tse loketseng ho fokotsa mocheso oa vulcanization o ka hlōloa.
Ntlha ea 7. Ho na le mesaletsa ka kopanelo
Ke ka lebaka la karolo ea sekhomaretsi sa sekhomaretsi ha se kopane ka ho feletseng, kapa ka lebaka la sekhomaretsi se nang le litšila kapa ho silafatsa oli, tharollo ke ho boloka sekhomaretsi sa preformed polokelong, lipalangoang, ho kenya sekhomaretsi se hloekile, ho thibela tšilafalo.
Ntlha ea 8. Ho hloka sekhomaretsi
E amana le sebopeho sa hlobo le mokelikeli oa sekhomaretsi. Mofuta o koetsoeng o ka hlahisa khaello ea sekhomaretsi ho feta hlobo e bulehileng. Tharollo ke ho lokisa mokelikeli oa rabara le ho bula lesoba la moea le lesoba lesoba la hlobo.
Ntlha ea 9. Deformation ea sehlahisoa
Ke ka lebaka la fluorine rabara shrinkage lebelo le leholo, ka mor'a ho bōpa sehlahiswa shrinkage anisotropy, coefficient ea katoloso ea mocheso ea rabara ka litsela tse fapaneng e fapane, tse peli vulcanization tshebetso tla theha eketsehileng cross-linking, haholo-holo karolo ea vulcanization tlas'a sebabole, vulcanization tse peli tsa sehlahisoa, sovulcanization ho feta ka nako e hlakileng ea deformation. ho qoba vulcanization tse pedi tsa deformation ya sehlahiswa.
Ntlha ea 10.Mould stain serious phenomenon
Ka kakaretso re sebelisa rabara ea fluorine ea mofuta oa 26, tsamaiso ea phenol vulcanization, ts'ebetsong ea vulcanization e tla hlahisoa HF, ke acid e matla haholo, e na le phello e kholo ea ho senya hlobo, mokhoa oa ho eketsa acid e monyang ke ho monya HF e hlahisitsoeng, ho thibela tšilafalo ea hlobo. Tharollo ke ho sebelisa calcium hydroxide le magnesium oxide e lekaneng ho latela mokhoa, tekanyo ea kakaretso ke likarolo tse 6 le likarolo tse 3, 'me boka ba boka ba Brazil bo ka ekeletsoa ka foromo, e ka fallelang holim'a rabara nakong ea vulcanization ho etsa filimi ho thibela hlobo hore e se ke ea silafala.
Lintho tse ka holimo tse leshome tse tloaelehileng tse sa tloaelehang tlhahisong le ts'ebetsong ea rabara ea fluorine li ka rarolloa ka mehato e sa tšoaneng.
