Epoxy resin lwemigexo nemihlobiso kuwo

Epoxy resin lwemigexo kuyinto yesimanje amakhemikhali impahla kokuba ithandwa enkulu phakathi amakhosi abasungula ngezandla imihlobiso. angakhiqiza imikhiqizo ukulingisa ngokugcwele ingilazi abangelwa yisisindo plastic. ukubukeka kakhulu ezikhangayo ngezinto zemvelo (Izigaxa, izimbali omisiwe, amahlamvu, njll), egcwele isicwebezelisi esobala.

Abantu abangekho qakala ezihlotshiswe kahle futhi uyawuthanda ekudaleni zonke izinhlobo yezandla ngezandla zabo, ukunikela ndawonye ukuba afunde lokho epoxy ubucwebe, iziphi izimiso kanye ubuqili sisebenza naye. Njengengxenye sihloko sinikeza okuyinhloko ekilasini encane ekwenzeni Lilengela.

okuqukethwe ukufunda

Igama elithi "resin" kuyinto ngokuvamile inhlangano nge yemvelo imvelaphi izinto. Kodwa kulokhu sikhuluma umkhiqizo chemical. Ngaphandle, glaze uketshezi esobala, okuyinto yakhiwa izingxenye ezimbili, resin kanye hardener.

Lapho ngokujoyina impahla amakhemikhali basabela, polymerize nomunye. Imiphumela iba yinhlanganisela yokukhandleka ephelele resin sokwelapha. Ngaphambi polymerization e glaze ungakwazi ukwengeza fillers okuqinile okungase ukushintsha izakhiwo okuholela impahla plastic ohlangothini oyifunayo.

Okunhlobonhlobo amapulasitiki eguquliwe

Made epoxy resin ngezandla zabo ngesisekelo brand owaziwa of production ezifuywayo glue - EKF futhi EAF. Ungathenga nabo izitolo abathengisa izesekeli yasendlini. emaphaketheni elincane 280g kubiza ruble mayelana 70-80.

Isilinganiso resin Ushintshe futhi hardener kufanele sibe ububanzi 8: 1 - 10: 1. Chemical polymerization inqubo kwenzeka emazingeni okushisa okuvamile futhi kuthathe amahora amaningana. Ukuze uthole solidification ephelele kuzothatha okungenani amahora angu-12. I-ejenti sokwelapha i epoxy resin kuthinta izinga polymerization: isikhathi eside kunaleso lakhe ukwakheka, sivala ngokushesha ukuma umkhiqizo. Isilinganiso izakhi ezidingekayo ukukala ngokunembile kakhulu - ke oluthinta ngqo umphumela wokugcina.

Omunye umkhiqizo chemical yasekhaya umkhakha - epoxy resin ED-20. Njengoba kuba ukhululekile kakhulu ukusebenza ekhaya, futhi intengo ikhange nakakhulu (isigamu intengo EKF futhi i-EAF). A ethile okuphawulekayo isembozo esikhulu: 6 kg kanye kg resin 1 - hardener.

On ukudayiswa ungathola imikhiqizo ezimbili-ingxenye womshini angaphandle. Kususelwa kubo, ukwenza imikhiqizo kakhulu i resin epoxy. Ngaphandle impahla main engahleliwe iphakethe zingatholakala amagilavu, plastic amakopi wokumeda, ngokhuni eshukumisayo induku. Lezi kits ezibizayo kuka nozakwabo yasekhaya. Isilinganiso ukuxuba kubo zingase zishintshe kakhulu: 2: 1, 1: 1, noma ngenye indlela. Kungenzeka ukuthi ingxenye kuyodingeka ukubala besebenzisa ifomula ekhethekile. Kunoma ikuphi, kuzomele ulandele izincomo yomenzi.

Qaphela emsebenzini

Epoxy resin kabanzi lisetshenziswe ukwakhiwa, umhlobiso imisebenzi kanye ekunyatheliseni ukukhiqizwa. impahla eluhlaza ngezinhloso lobuchwepheshe kunomphumela oqinile chemical iphunga ukuhwamuka abakucasulayo ku umgudu wokuphefumula. Lapho besebenza indaba ezimbonini ukusebenzisa imishini zokuzivikela.

Epoxy resin abakhiqizi imigexo nemisebenzi zokuhlobisa omethembayo engalethi umonakalo. Nakuba izinyathelo zokuphepha namanje kufanele banganakwa. Ngokuvamile, basuke babe ukwaziswa okuningiliziwe isembozo yokuqala, kodwa kuyasiza ukuba basho manje. Ngakho izinyathelo zokuphepha lapho esebenza enamathela chemical:

• ukuze resin abakutholanga ezandleni zakho kanye nolwelwesi lwamafinyila kufanele basebenze amagilavu iraba kanye Lobe zokuzivikela;
• esimweni ejenti zamakhemikhali falling emzimbeni ukuba ngokushesha beyikhipha kusukela isikhumba futhi uhlambulule ne ohlanzekile izindawo amanzi contact;
• Ngeke usetshenziselwe yokukhiqiza izihloko resin nabo ukudla;
• watusa isikhala ukusebenza uphahlwe ifilimu plastic noma ephepheni elenziwe bushelelezi ;
• umsebenzi wenziwa endaweni kahle umoya.

Nge ukushisa

Inqubo polymerization kuhambisana wenkululeko ukushisa. Ngenxa yokusabela chemical resin kungaba eliwu degrees 60. Lesi sici okufanele sicabange ngazo lapho ekhetha emakamelweni thusi, kuyinto efiselekayo ukuthi zingabantu ukushisa ukumelana.

Oku-Ukushisa yezingxenye kokuqala esheshisa inqubo polymerization. Nge lokushisa okwandisa kwandisa fluidity we liyancipha resin kanye viscosity yayo. Ukuthululela epoxy resin imininingwane ocolekile liyobe ngokushesha futhi kangcono, uma ikhambi liyini Preheat kuya 25-30 ^C. Khona-ke, it is wasungula yamathebhu futhi ngemva kwalokho kuphela hardener.

Ukwehlisa izinga lokushisa futhi umswakama ngokweqile zibulale polymerization. Ngaphansi kwalezi zimo angase inqubo imisiwe kakhulu noma ukhetha ukungabuthinti nhlobo ukufinyelela ekupheleni.

Thina sifinyelele ukuvumelana oyifunayo

Nakuba resin epoxy lwemigexo akafakanga esinyathelweni polymerization, ke unawo izakhiwo uketshezi viscous. Uma sethula yamathebhu lomisile isixazululo, kungase awe phansi (usimende, Gypsum) noma ifike kwamanzi (chips izinkuni, ukhokho). Lesi sici impahla okufanele sicabange ngazo lapho ekhetha isikhunta futhi ukwaba ingxenye yayo.

nezinsiza Isicelo

Ubunzima main ukuthi uzobe ebhekene enqubeni - emoyeni abagcwele. Uma uvumela ingxube ume ezimbalwa noma kancane efudumele wakhe up, ziyabuya phezulu. Ukuqeda Bubbles ukunamathela ifomu, ungasebenzisa i lokuvungula abavamile. Ukuze resin epoxy ngezandla zabo ukuze uthole ukungaguquguquki ephelele, wenze ethela ukusakaza mncane ngokusebenzisa strainer esihle.

Ngo ukusebenza ocwebezelayo elula ukusebenzisa izinto alahlwayo ukupheka izingxenye ngabanye ingxube. kuhambisana kahle kule izimbiza injongo amaplastiki imikhiqizo yobisi (yogurt, ushizi). Govuza ingxube izinti ukhululekile lokhuni olukulesi ayisikhilimu.

Ukukhiqiza sokuphuza isilinganiso esengeziwe somuthi olunembile izingxenye, ungasebenzisa imijovo yezokwelapha letingemasayizi lahlukene. Phawula ukuthi kule ndaba, ugcwalise resin epoxy kufanele kwenziwe phezulu ithangi. A hardener ngomshini phakathi isipetu ngendlela ezivamile.

Isikhunta ukulingiswa, kuyinto efiselekayo gcoba isixazululo zokuzivikela. Kungaba esikhundleni ezivamile ongahluziwe jelly noma amapulangwe aphansi ze-mastic. Sebenzisa ungqimba elincanyana futhi ukuze ususe noma ikuphi ngokweqile okuyinto swab ukotini. Uma amafomu zakhiwe abicah, polyethylene, noma Plexiglas, pre-Lubrication akudingeki.

Khuluma mayelana excipients

izithasiselo okuqinile kanye nama-liquid nomthelela yini etholakala ngenxa imihlobiso ezenziwe epoxy resin. Ezisetshenziswa kakhulu ngalezi zinhloso usimende, ukhonkolo, wokulinganisa, chips izinkuni noma bezinto (spangles). Okuqukethwe izithasiselo in ingxube Imininingwane - hhayi ngaphezulu kuka-50%.

I excipients ezomile unikeze plastic kanzima, kodwa ziyaqothuka. plasticizers ketshezi zisetshenziselwa iwukudambisa i izinga engathandeki futhi ekuthuthukiseni ductility material. Ukwengeza elula futhi ezingabizi kakhulu kungase kube uwoyela ocolisekileyo. Ngokuvamile, esisodwa noma ezimbili amathonsi kwanele.

Ukukhetha Ukwakheka womshini we elengayo

Dala umhlobiso ekhethekile kuyosisiza ecacile epoxy resin lwemigexo. Njengoba isibonelo esingazithatha Ukwakheka ezimbili ingxenye ezivezwa inkampani French Gedeo Pebeo nomthamo 150 ml.

Material ilingisa kahle ingilazi, futhi isetshenziswa hhayi kuphela okwenza imihlobiso, kodwa futhi ngoba multi-ungqimba ezinengilazi, ebusweni umhlobiso, nokubuyiselwa imifantu. Isisekelo isicelo kungenzeka ingilazi, zensimbi, zobumba, i-silicon plastic, izinkuni zaveza. Glaze kuyinto esobala kakhulu, ayinaphunga kulula ukulungiselela. Umkhiqizo osuphelile libhekene amandla okusezingeni eliphezulu futhi ongenalo ophuzi ngokuhamba kwesikhathi.
