1. Synthetic Calcium Silicate - Thermal Insulation White Filler
Synthetic calcium silicate e teng ka mefuta e 'meli: meaho ea porous/spherical le ea ceramic-fiber-like fibrous structures. Leha ho na le liphapang tsa sebopeho le morphological, ka bobeli li sebetsa e le li-fillers tse tšoeu tsa mocheso o phahameng tse hanyetsanang le mocheso o phahameng.
Synthetic calcium silicate fiber ke botsoalle ba tikoloho lethepa e sireletsehileng ea ho kenya mocheso oa mochesoe nang le khanyetso e phahameng ea mocheso ho fihlela ho 1200-1260 ° C. Phofo ea fiber e entsoeng ka ho khetheha e entsoeng ka calcium silicate e ka sebetsa e le thepa e matlafalitsoeng bakeng sa ho kenya mocheso o phahameng.
Ho sa le joalo, li-synthetic porous kapa spherical calcium silicate, li na le bosoeu bo phahameng, boiketlo ba ho kenngoa, mohaho o ruileng oa nanoporous, litekanyetso tse phahameng tsa ho monya oli (ho fihlela ho 400 kapa ho feta), le tokoloho ho libolo tsa slag kapa likaroloana tse kholo. E na le lits'ebetso tse netefalitsoeng ka har'a mohatsela o phahameng oa mocheso le liphanele tse sa keneleng mollo, tse bonts'ang monyetla oa ho kenyeletsoa ka har'a lisebelisoa tse hananang le ablation ho fana ka mocheso o phahameng oa mocheso.
Lisebelisoa tse ling li kenyelletsa: li-additives tse nang le phofshoana, lijalo tsa phofo tse futhumatsang mocheso o phahameng, lijari tsa litlolo tse nkhang hamonate, li-anti-drip agents, lisebelisoa tsa brake pad friction, rabara ea silicone e nang le khatello e tlase le oli e itšebetsang ea silicone, li-filler tsa pampiri, jj.
2. Sekhahla sa Porous Magnesium Aluminium Silicate– Thermal Insulation & High-Mocheso Resistance
Minerale ena ea silicate e hloka calcination ea mocheso o phahameng ka refractoriness ho fihlela ho 1200 ° C. Haholo-holo e entsoe ka silicate ea aluminium ea magnesium, e na le sebopeho sa porous se ruileng se fanang ka matla a maqhama a phahameng, ho hanyetsa metsi ho matla, nako e telele ea ho hanyetsa, le litšenyehelo tse phahameng.
Mesebetsi ea eona e ka sehloohong e kenyelletsa ho kenya mocheso o phahameng oa mocheso, ho fokotsa boima ba 'mele, ho matlafatsa refractoriness, le ho ntlafala ha ablation resistance le ho kenya mocheso oa mocheso bakeng sa likarolo tsa carbon le casings. Lits'ebetso li kenyelletsa lisebelisoa tse kentsoeng ka ceramicized, lirafshoa tsa pele tse sa cheng, lisebelisoa tsa ho kenya letsoho tse sa cheseheng, le lisebelisoa tse thibelang ho chesa mocheso.
3. Ceramic Microspheres - Ho hanyetsa Mocheso o Phahameng, Thermal Insulation, Matla a Hatellang
Ha ho pelaelo hore li-microspheres tsa khalase tse se nang letho ke lisebelisoa tse ntle haholo tsa ho futhumatsa mocheso, empa ho hanyetsa mocheso oa tsona ha hoa lekana. Lintlha tse bonolo tsa tsona hangata li tloha ho 650-800 ° C, 'me mocheso o qhibiliha ho 1200-1300 ° C. Sena se lekanyetsa ts'ebeliso ea bona maemong a tlase a mocheso oa mocheso o tlase. Tlas'a maemo a phahameng a mocheso joalo ka ceramicization le ablation resistance, li fetoha tse sa sebetseng.
Li-microsphere tsa rona tsa ceramic tse se nang letho li rarolla bothata bona. Haholo-holo e entsoe ka aluminosilicate, e fana ka khanyetso ea mocheso o phahameng, ho kenya letsoho ho futhumatsang mocheso, ho hanyetsa ho phahameng, le ho hanyetsa ho hoholo hoa fracture. Likopo li kenyelletsa li-additives tsa silicone ceramic, lisebelisoa tsa ho kenya li-refractory, li-additives tsa mocheso o phahameng bakeng sa li-resin tse entsoeng ka tlhaho, le lisebelisoa tsa rabara tse hanyetsanang le mocheso o phahameng. Likarolo tsa bohlokoa li kenyelletsa sebaka sa sefofane, tlhahlobo e tebileng ea leoatle, lisebelisoa tse kopaneng, likoaelo, li-insurance, indasteri ea peterole le lisebelisoa tsa ho kenya letsoho.
Ena ke spherical micropowder e sa cheseheng haholo, e bonolo haholo ho e kenyelletsa (ho fapana le li-microspheres tsa khalase tse sekoti, tse hlokang ho hasana pele kapa ho fetoloa bakeng sa ho eketsoa ka nepo) 'me e bonts'a khanyetso e ntle haholo ea ho peperana. Tšobotsi ea eona e khethollang ke hore ke thepa e bulehileng ka holim'a metsi e sa phaphametseng holim'a metsi, e etsang hore ho be bonolo ho teteaneng le ho lula.
Ho phaella moo, ho buuoa ka bokhutšoanyane kaphofo ea airgel- sesebelisoa sa maiketsetso sa silika sa maiketsetso. Airgel e tsejoa ka ho pharaletseng e le insulator e ntle ea mocheso, e fumanehang ka mefuta e fapaneng ea hydrophobic/hydrophilic. Sena se lumella khetho ea mekhoa e nepahetseng ea kalafo e ipapisitseng le li-resin substrates, ho sebetsana le mathata a phofshoana ea airgel ea ho hasana ha bobebe le ho ntlafatsa phepelo ea eona. Li-pastes tsa airgel tse thehiloeng metsing le tsona lia fumaneha bakeng sa ho kenngoa habonolo mecheng ea metsi.
Lintho tse ikhethang tse nang le porous tse thibelang mocheso oa phofshoana ea airgel li nolofalletsa ts'ebeliso ea eona ho: - Rabara le li-additive carriers tsa polasetiki - Thermal insulation materials bakeng sa libeteri tse ncha tsa matla - Liaparo tsa ho haha mohaho - Thermal insulation textile fibers - Liphanele tsa ho haha mohaho - Liphahlo tse thibelang mollo - Li-adhesive tse nang le mocheso oa mocheso.
