Phenolic Resin

Ponolic Resin e boetse e bitsoaBakelite, hape e tsejoang joalo ka phofo ea Bakellite. Qalong e se nang 'mala (e tšoeu) kapa e putsoa - ntho e pepesitsoeng,' maraka o moputsoa ho etsa hore e shebahale e le khubelu, e putsoa, ​​e putsoa ebile e phollatsi le phofo. Hanyetsanang le Alkali a fokolang le a fokolang, e tla bola ka tlasa acid acid e matla le pokello haeba e le Alkali ea matla. E qhibiliha ka aleeti, metsi, joala le li-solvent tse phelang. E fumanoa ke polao ea phenolic aldehyde kapa e tsoang ho eona. Pheko ea Phenolic e tiile ke ntho e mosehla, e le 'mala o moputsoa, ​​o reretsoeng ka lebaka la phenono e lekaneng, e tsitsitseng ka metsing, e fokolang ea Alkali. Ke sebaka se entsoeng ke Polaol le Formaldehyde tlasa maemo a li-catalyst, ho se nke lehlakore le ho hlatsoa metsi. Ka lebaka la khetho ea catalyst, e ka aroloa ka mefuta e 'meli: Thermosetting le Thermoplane. POSINIC Resin e na le likhanyetso tse ntle tsa asiti, tsa maikutlo le ho hanyetsa mocheso, lienjiniere tsa ho sesa le li-grandries tsa ho sesa le indasteri ea linotsi.

Ponolic Resin Ponolic Ponolic Ponolic Ren ponolic e thehiloeng ke polao ea Phekono le formaldehyde ka har'a acidic mechi ea Acidic. E ka qhibiliha ho Ethanol 'me e be tsosoloso ka ho kenyelletsa 6 - 15% urotropine. E ka thetsoa ka 150°C ebile o na le matla a itseng. le thepa ea motlakase ea motlakase.

Karolo e ka sehloohong ea ponolic Resin ke ho hanyetsa haholo ha mocheso o phahameng, 'me e ka boloka botšepehi ba eona ba sebopeho le botsitso bo phahameng esita le mocheso o phahameng haholo. Therefore, phenolic resins are used in high temperature fields, such as refractory materials, friction materials, adhesives and foundry industries.

Sesebelisoa sa bohlokoa sa ponolic Resin se tšoana le binder. Bolulo ba phenolic ha bo qaqhele ebile bo tsamaisana le mefuta e mengata ea mefuta e mengata ea manyolo le li-inorgargan. Ka nepo bo-Runolic ba silafetseng ba phenchic ba li-panolic tse kolobisang haholo. Le ka mor'a hore Tšisoa ke Matla - Ho Ho Ho Hohala Ho ka Fana ka Matla a Leseli Ho Hloka Mechafatsong ea mocheso le lisebelisoa tsa motlakase, lisebelisoa tsa likhohlano le ho baleha.

Metsi - Liponto tsa li -Volic tse qheletsang Panolic kapa lino tse qheletsang li-conolic tse kentsoeng ka matla, masela a koalehileng, jj.

Thepa ea Phenolic Resin:

Ts'ebetso ea mocheso o phahameng: Karolo ea bohlokoa ka ho fetisisa ea Phenolic Resin ke bora ba mocheso bo phahameng, esita le mocheso o phahameng, o ka boloka botšepehi ba sona le botsitso.

Matla a Bond: Kopo ea bohlokoa ea ponolic Resin e tšoana le binder. Bolulo ba phenolic ha bo qaqhele ebile bo tsamaisana le mefuta e mengata ea mefuta e mengata ea manyolo le li-inorgargan.

Tekanyetso e phahameng ea khabone: Tlas'a maemo a kenang a khase ka mocheso oa hoo e ka bang 1000°C, Bolulo ba Phenolic e tla hlahisa masala a mangata a khang ea Carbon, e ka kenyelletsang ho boloka botsitso ba ho tsitsipahla tsa Phenolic.

Mosi o tlase le chefo e tlase: Ha e bapisoa le sistimi e meng ea litšitiso, sistimi ea Phellic Res e na le melemo ea mosi o tlaase le chefo e tlase. Tabeng ea motsoako, mokhoa oa Phenolic oa Resi o tla theoha butle oa ho felisa hydrogen, hydrocarbons, mouoane oa metsi le khabone. Mosi o hlahisitsoeng nakong ea ts'ebetso ea botsitso e nyane, 'me chefo e tlase haholo.

Ho hanyetsa ka lik'hemik'hale: Moroallo - Phokotso ea Bononolic e ka hanela ho bola ha lintho life kapa life tsa lik'hemik'hale. E joalo ka peterole, linoko, joala, glycol, mafura le hydrocarbons tse fapaneng tsa hydrocarbork.

Phekolo ea mocheso: Phekolo ea mocheso e tla eketsa mocheso oa ho fetoloa ha khalase ea mochini o folisitsoeng, o ka ntlafatsang thepa ea pokello ea thepa.

Foumality: Bonolic Feam ke mofuta oa polasetiki ea foam e fumanoeng ke pherekano ea phenolic. Ha ho bapisoa le Polystyrene Foam, Polyvinyl Chloride Feam, Lisebelisoa tse ling tse neng li hatella 'marakeng o mong oa polyviny, e na le ts'ebetso e khethehileng ea ho tlohela lelakabe.
