Thepa e Fetotsoeng ka Katleho ka ho Fetisisa: Khalase ea Fiber e Matlafalitsoeng e Fetotsoeng ea Phenolic Resin (FX-501)

Phenolic Faeba ea Khalase, har'a li-resin tsa pele tsa maiketsetso tse entsoeng indastering, hangata ke polycondensate e entsoeng ke polymerization ea li-phenol le aldehydes ha ho na le catalyst ea alkaline. Lisebelisoa tse ling li kenngoa ho hokahanya sebopeho sa macromolecular, li se fetola sebopeho sa macromolecular se sa qhibiliheng le se sa keneng, ka hona se fetoha sebopeho se tloaelehileng. thepa ea polymer ea thermosettingLi-resin tsa phenolic li ananeloa haholo ka lebaka la thepa ea tsona e ikhethang, ho kenyeletsoa le ho lieha ha malakabe ho babatsehang, botsitso ba litekanyo, le matla a matle a mechini. Litšobotsi tsena li susumelitse lipatlisiso tse pharaletseng le ts'ebeliso ea thepa ea resin ea khalase ea phenolic fiber.

Ha moruo oa indasteri o ntse o hatela pele ka potlako, litlhoko tse ntseng li eketseha li beoa tšebetsong ea phenolic Lisebelisoa tsa Faeba ea Khalases. Ka lebaka leo,likhoele tsa khalase tsa phenolic tse fetotsoeng tse matla haholo le tse hanelang mochesoli ntse li ntlafatsoa le ho sebelisoa haholo. Resin ea phenolic e ntlafalitsoeng e matlafalitsoeng ka khalase (FX-501)hajoale ke e 'ngoe ea thepa ea resin ea khalase ea phenolic e fetotsoeng ka katleho e kholo. Ke mofuta o mocha oa thepa ea phenolic e fetotsoeng le e matlafalitsoeng e entsoeng ka ho kenyelletsa likhoele tsa khalase ho matrix ea pele ea resin ka ho kopanya.

Matlotlo a Mekaniki le Mesebetsi ea Karolo

Phenolic khalase faeba resinhangata e khethoa e le matrix bakeng sa thepa e sa tsofaleng, e sa tenyetseheng, le e hatelletsoengka lebaka la matla a eona a ho thapolla, ho hanyetsa di-solvent, le thepa e ntle ya mechini jwalo ka ho thibela malakabe. thepa ea matrixhaholo-holo e sebetsa e le sehokelo, e hokahanya likarolo tsohle ka tlhaho. Likhoele tsa khalaseli sebetsa e le li-unit tse ka sehloohong tse jarang mojaro ka thepa e sa tsofaleng, li fana ka bokhoni ba ho jara mojaro, 'me ts'ebetso ea tsona e phahameng e ama ka kotloloho phello ea ho matlafatsa matrix.

Karolo ea thepa ea matrix ke ho tiisa likarolo tse ling tsa thepa e thapollang, ho netefatsa hore meroalo e fetisetsoa ka ho lekana, e ajoa, 'me e abeloa likhoele tse fapaneng tsa khalase. Sena se fana ka matla le ho tiea ho itseng ho thepa. Likhoele tse tloaelehileng, ho kenyeletsoa likhoele tsa khalase, likhoele tsa tlhaho, Tšepe ea Tšepes, le likhoele tsa diminerale, li phetha karolo ea ho lokisa matla a ho thaepa a thepa.

Ho jara mojaro ka metsoako le tšusumetso ea litaba tsa faeba

Ka hare litsamaiso tsa thepa e kopaneng ea khalase ea phenolic fiber, ka bobeli likhoele le resin ea matrix li jara mojaro, ka likhoele tsa khalase tse setseng e le mojari oa mantlha oa mojaro. Ha metsoako ea faeba ea khalase ea phenolic e kobeha kapa e hatelloa, khatello e fetisetsoa ka ho lekana ho tloha ho resin ea matrix ho ea ho likhoele tsa khalase ka bonngoe ka har'a sebopeho, e qhalanya matla a tsamaisoang ka katleho. Ts'ebetso ena e ntlafatsa thepa ea mechini ea thepa e kopantsoeng. Ka hona, keketseho e loketseng ea dikahare tsa faeba ya khalase di ka ntlafatsa matla a dikompositi tsa faeba ya khalase ya phenolic.

Liphetho tsa liteko li bontša tse latelang:

• Metswako ea khalase ea phenolic fiber e nang le 20% ea fiber ea khalaseli bontša kabo e sa lekanang ea faeba, 'me libaka tse ling li bile li haelloa ke faeba.
• Metswako ea khalase ea phenolic fiber e nang le 50% ea fiber ea khalaseli bontša kabo e tšoanang ea faeba, libaka tse sa tloaelehang tsa ho robeha, 'me ha ho na matšoao a bohlokoa a ho huloa ha faeba ho hoholo. Sena se bontša hore lifaeba tsa khalase li ka jara mojaro hammoho, e leng se fellang ka matla a phahameng a ho thiba.
• Ha tekanyo ea fiber ea khalase e le 70%, dikahare tse feteletseng tsa faeba di lebisa ho dikahare tse tlase tsa resin ya matrix. Sena se ka baka diketsahalo tse "fokolang resin" dibakeng tse ding, tsa sitisa phetiso ya kgatello le ho baka maemo a kgatello sebakeng seo. Ka lebaka leo, thepa yohle ya mechini ya thepa e kopaneng ya faeba ya khalase ya phenolic e a fetoha. e atisa ho fokotseha.

Ho tsoa liphuputsong tsena, Ho eketsa fiber ea khalase ka botlalo ho ka khonehang ho tsoa metsoakong ea fiber ea khalase ea phenolic ke 50%.

Ntlafatso ea Tshebetso le Lintlha tse Susumetsang

Ho tsoa ho data ea lipalo, metsoako ea khalase ea phenolic fiber e nang le fiber ea khalase ea 50%pontsho e ka bang matla a ho kokobela a makgetlo a mararole matla a khatello a makgetlo a maneha e bapisoa le resin e hloekileng ea phenolic. Ho phaella moo, lintlha tse ling tse susumetsang matla a polasetiki e matlafalitsoeng ea khalase ea phenolic li kenyelletsa bolelele ba likhoele tsa khalasele tsa bona tataiso.
