Epoxy resin: buyindlela esisemqoka kuyo yonke imikhakha

Epoxy Resin - izidakamizwa kokuba ukumelana acid, lezisekelo futhi halogens. Kuyinto zokwenziwa oligomer. Ingasetshenziselwa ukunamathisela cishe noma yikuphi okubalulekile. In the state ketshezi kuyinto epoxy resin ecacile, okuyinto has umbala ophuzi, futhi ngemva lukhuni kuba ensundu cishe ephephile ezempilo. Nokho, ukusetshenziswa kwalo lapho kungase kube contact nebangomuso izihlanzi, ingxenyenamba sol-leachable engenakwenzeka. In the state ketshezi kuba enobuthi kakhulu, ngakho ukusebenzisa kwayo kudinga ukunamathela iqoqo imithetho.

Yiqiniso, i-ukusondelana izitsha noma ezinye izinto esingazisebenzisa mbeni ukudla noma ukuphuza amanzi, asikwazi ukusetshenziselwa lokhu injongo kukhona nezinye izinto. Nokho, ngenxa izakhiwo zabo, resin epoxy iyithuluzi elibalulekile e ezibanzi kakhulu izimboni. ukusetshenziswa ezimbili eziyinhloko-material: njengenhlangano ingcina futhi impregnation. Ngosizo lwawo ukuvikela ukugqwala ngokhonkolo, metal, ukukhiqiza isikhunta, iglu ezihlukahlukene, ngisho kubaluleke kakhulu iqhaza cishe wonke amagatsha zobunjiniyela. Epoxy resin ne-fiberglass ayaqala izinto ukwenziwa ingilazi fibre, okuyinto kabanzi ukwakhiwa, boat- futhi umkhakha emoyeni. Futhi, kuqala isetshenziswa ukugcwalisa electronics ngisho ekuklanyweni.

Epoxy resin isetshenziswa Ngohlelo nge hardener. Lapho ukwelashwa ukushisa Akwamukelekile endaweni yasekhaya, zisetshenziswe workshop encane izidakamizwa abandayo. Futhi imikhiqizo ebalulekile, yakhelwe ukusebenza ngesikhathi imithwalo okusezingeni eliphezulu static futhi ashukumisayo ezindaweni onakalisayo - hot elapha ejenti. Kulokhu, grid luthe ukuqina nokubopha molecule polymer. Ngaphezu kwalokho, kukhona i-resin epoxy futhi hardeners, elakhelwe nemibandela umswakama high, amanzi anosawoti.

Ukusebenza ukuphila kwakhe, kufanele kuqondwe ukuthi lemagalagala hardener yayo ukusabela exothermic, kanye enkulu isisindo polymer, aba maningi ukushisa. Kule ndaba kubalulekile ukukhetha inombolo elungile ejenti, kanye correlate ke ngenhloso yokusetshenziswa, ngenxa yalokho, kufanele uthole umfaniswano (akukho Bubbles) okuqinile. Ngaphezu kwalokho, lokho okwenziwa resin kanye hardener awushintsheki, futhi ngemva kwalokho thermoset, Thermoplastic ngokungafani ayikwazi ancibilike noma chaza ukuthi sibuyekeze yi. Izinto ezivamile futhi ezingabizi angawokuphulukisa epoxy izinto manje sezibhekwa njengezindawo Pepa, Deta, TETA, TEPA futhi №1 (hexamethylene diamine ziyoncibilika ETHYL utshwala). Ngenxa yokuthi abavamile kwakwakhe ezimbili ingxenye - into kunalokho ethambile, umswakama waso luyanda kokwengeza enye ingxenye. Lo msuka ibizwa ngokuthi "umthelela lwewashi", kungase abe ezahlukene amakhemikhali ukwakheka kanye, kuye ngokuthi lokhu, anezici ezithile. bamakhemikhali True baye bathola izinto unekhono ukwenza kokubili njengoba hardener, futhi lwewashi nomthelela.
