Na u tseba litšobotsi tse ‘maloa tsa epoxy glass fiber pipe?

The epoxy glass fiber tube e entsoe ka lesela la fiber ea khalase e se nang alkali ea motlakase e kentsoeng ka resin ea epoxy, e besitsoeng, ‘me e sebetsoa ka ho tobetsa ka ho chesa ka har’a hlobo e entsoeng. Karolo ea sefapano ke molamu o chitja. Molamu oa lesela la khalase o na le thepa e phahameng ea mochine. Bokaholimo ba epoxy glass fiber tube e lokela ho ba boreleli ntle le li-bubble, litšila tsa oli le litšila. Mmala o sa lekaneng, ho hohla ho fokolang, joalo-joalo kaofela li ka har’a sebaka se lumelletsoeng. Liphaephe tsa epoxy fiberglass li sebelisoa bakeng sa likarolo tsa sebopeho sa ho kenella ka har’a lisebelisoa tsa motlakase, maemo a mongobo a tikoloho le oli ea transformer.

Litšobotsi tsa liphaephe tsa fiber ea khalase ea epoxy li batla li pharalletse, ‘me sebaka sa kopo se batla se pharaletse,’ me mefuta e fapane. Resin, alafi le sistimi e fetolang e ka batla e ikamahanya le litlhoko tsa lits’ebetso tse fapaneng foromong, ‘me mefuta e ka ba ho tloha ho viscosity e tlase haholo ho isa ho lintho tse matla tse qhibilihang. Ea bobeli, ho hloekisa ho bonolo haholo. Khetha mefuta e fapaneng ea mefuta e fapaneng ea pheko, ‘me sistimi ea epoxy resin e ka phekoleha ka mocheso oa 0-180°C.

Ntho e ‘ngoe eo ke lokelang ho e bua ke hore e na le ho khomarela ka matla. Ho na le lihlopha tsa polar hydroxyl le li-ether bond ka har’a ketane ea molek’hule ea epoxy resin, e etsang hore e be le mamarelo a phahameng linthong tse fapaneng. Ho fokotseha ha resin ea epoxy ho fokotseha ha ho phekoloa, ‘me khatello ea ka hare e hlahisoang e nyenyane, e thusang ho ntlafatsa matla a ho khomarela. E boetse e na le shrinkage e tlase. Boitšoaro pakeng tsa epoxy resin le pheko e etsoa ka karabelo e tobileng ea ho eketsa kapa karabelo ea ho bula polymerization ea lihlopha tsa epoxy ka har’a molek’hule ea resin, ‘me ha ho na metsi kapa lihlahisoa tse ling tse senyehang. Ho ea ka lintlha tse nepahetseng, ha li bapisoa le resin ea polyester e sa tsitsang le resin ea phenolic, shrinkage nakong ea phekolo e tlaase haholo, hoo e ka bang 2%. .
