Polyester resin kanye epoxy resin: ngokungafani, izici kanye nokubuyekeza

Epoxy kanye polyester inhlaka, umehluko okuyinto ezocatshangelwa kulesi sihloko basonta ekilasini thermosetting. Lokhu kusho ukuthi ngemva kwenqubo solidification abakwazi ibuyiselwe esimweni liquid. Bobabili ukwakhiwa izindlela ezihlukene, ebheka umgamu wawo. Ukuze siqonde injongo lezi zinto ziwusizo kakhulu sokuba bajwayelane ukubuyekezwa epoxy kanye polyester inhlaka.

epoxy

Epoxy libhekisela izinto zokwenziwa imvelaphi. Ngesimo okumsulwa akusiyo ezifanele ukusetshenziswa njengoba self kuya okuqinile isimo inkinobho ayikwazi ukwenza. Ukuze uthele resin epoxy yengezwe ngo olinganise lesifanele hardener ekhethekile.

Ukuze ukusetshenziswa ngokufanele kuyadingeka ukwazi izinzuzo nezingozi i resin epoxy. Resin yalolu hlobo iyigugu ngoba amandla aso izici. Kuyinto ukumelana nolaka chemical compounds ezifana acid kanye alkalis. Izinzuzo epoxy zihlanganisa: ukuncipha ngokulinganisela, okusezingeni eliphezulu bafake ukumelana nokuqina kwayo kakhulu. inqubo solidification vuko lwenzeka phakathi wonke lokushisa uhla, kodwa Kunconywa sokuphila kusukela degrees +18 ukuze +25. Hot uthele indlela isetshenziswa womshini anda amandla okwazi withstanding imithwalo kakhulu.

Lolu hlobo inhlaka elisetshenziswa umkhakha futhi ekhaya. Ububanzi bokusebenzisa yabo buya kabanzi ngokwakhiwa ezaqanjwa entsha nge izakhiwo elungiselelwe. Ngenxa kuhlangana izinhlobo ezahlukene inhlaka epoxy futhi hardeners zingaba umkhiqizo wokugcina ezinezici ezihluke kakhulu.

Ukusebenzisa epoxy resin

Epoxy uhlobo resin lisetshenziselwa njengoba material for kunenze nisondelane evele: izinkuni, isikhumba, insimbi kanye nezinye non-ukungena nakwamanye amazwe. ukwakhiwa okunjalo amangalelwe electronics, ubunjiniyela kanye izindiza. Fiberglass, ngenkuthalo esetshenziswa ekwakheni, nazo eyenziwe epoxy. Resin esetshenziswa ukuze ungangenisi amanzi phansi futhi izindonga, kuhlanganise zangaphandle. Iphele imikhiqizo eyenziwe fiberglass, ngemva ukugaya nokuhlanganisa ukucutshungulwa ethandwa kakhudlwana umhlobiso Interiors kwezakhiwo.

Ukwelapha i-ejenti ukuze epoxy resin

Epoxy impahla siqukethe izingxenye ezimbili, okuyinto emva ukuxuba inqubo polymerization iqala. Uphiko abangela solidification we resin epoxy libizwa hardener. Kuye ukusetshenziswa inhlaka ezahlukene kanye hardeners ingalungiswa ngempela ngokungafani nenye epoxy.

Ingxenye ye-ejenti sokwelapha e ukwakheka ziyahlukahluka futhi kuncike ngokuyinhloko ebangeni resin. epoxy resin polymerization ukuphendula awushintsheki, impahla okusho ukuncibilika kwezinguzunga uye eqina akunakwenzeka.

Kuyiphutha ukuthi bakholwe ukuthi lapho eziyihaba inani hardener ukuqina kuyoba ngokushesha. Indlela esebenzayo kunonophisa luhlelo - okwandisa izinga lokushisa ingxube. Ukwandisa izinga lokushisa ezisebenza lamadigri 10 Ingasheshisa inqubo izikhathi 3. Kukhona izingxenye ekhethekile ngalezi zinhloso emakethe. Kukhona futhi Izingxube epoxy, solidifying at okushisa aphansi.

Ukukhetha olungalungile inani hardener kuba nomthelela ongemuhle izinga umkhiqizo osuphelile. Ngokuyinhloko incipha izikhwepha zayo kanye ukumelana namakhemikhali. Lapho inani elincane hardener enamathelayo ukungaguquguquki izingxenye, nge ngokweqile polymer phezu impahla lwabelwe. Olinganise njalo iningi resin / hardener 1/2 noma 1/1. Ngaphambi ukuxuba, kutuswa ukuba ufunde imiyalelo ngoba ilungile ingxenye isilinganiso.

polyester resin

akha resin okunjalo e ukucutshungulwa alcohols izinjongo ezikhethekile. Indaba isisekelo polyester. imithi yokususa ingcekeza elenkani ezikhethekile kanye inhibitor esetshenziswa kunonophisa luhlelo sokwelapha. Kuye isicelo ezibonakalayo, ungase ube isakhiwo ezahlukene kanye izakhiwo. Umkhiqizo kwaphumela idinga okunye ukwelashwa okuhloswe ngayo ukwenza ngcono ukuvikelwa amanzi UV ngemisebe ngokumelene. enamathela engeziwe futhi sithuthukisa izici amandla komkhiqizo. Polyester resin, epoxy ngokungafani, libhekene ongaphakeme izakhiwo lokukhanda. Kodwa ngaleso poliefirku esifanayo inenani ongaphakeme, sibonga ngalo impahla zithandwa kakhulu.

inhlaka ezinjalo zisetshenziswa kakhulu ekwakheni ukwakhiwa, yezimoto, shipbuilding nokukhiqizwa kwezincwadi iziqukathi zamakhemikhali. izingxenye Polyester lapho exutshwe ingilazi ukwakha okusezingeni eliphezulu amandla kwakwakhe. Ngenxa impahla okuholela isetshenziswa womshini awnings, uphahla ezakhiweni nokukhanya.

Resin polyester nakho kufakwe yokwakheka itshe yokufakelwa. Made ngokusebenzisa le plastic ingxenye isetshenziswa womshini ifasitela Sills, eshaweni ezivalekile, ngodonga kanye izakhi okuhlobisa. Polyester inhlaka, ngokungafani epoxy, staining kalula.

Izinzuzo esemqoka polyester uhlobo resin

Polyester resin, ngokungafani epoxy, has a usizo enkulu. Ngemva ukuxuba, ukwakheka ingilazi iba izici amandla, beyizidlova izakhiwo steel. Ukuze lukhuni poliefirki aludingi izimo ezikhethekile okushisa. Sebenza nge-ke abhekwa okhandlayo kancane, futhi impahla ushibhile.

Uyini umehluko?

Ukubuza umbuzo: "? Yikuphi okungcono, poliefirka noma epoxy", Wena kudingeka baqonde ukuthi kungani futhi lapho resin liyadingeka. Bobabili izinto babe elithola abo kanye nebubi, futhi leso sinqumo sokugcina kuncike kule mibandela yokusetshenziswa, kanye nohlobo ebusweni lapho resin izosetshenziswa.

Epoxy inenani eliphakeme, kodwa okuhlala isikhathi eside. Ukuba kakhulu izakhiwo ingcina ngoba uvalwe uxhuma ezahlukene isakhiwo ebusweni. Epoxy resin ezahlukene kusukela polyester umkhiqizo ukuncipha azinakwa, izici mechanical kangcono futhi ukumelana ukugqoka.

Ngakho, ngokungafani poliefirki, epoxy badinga isikhathi esengeziwe solidification, okuyinto kubambezela inqubo yokukhiqiza izingxenye le nto. Ukusebenza nge resin enjalo ihambisana ezokuphepha kuqiniswa: lokha abafundi basebenza impahla ketshezi kubalulekile ukusebenzisa amagilavu sokusingatha imikhiqizo okuqinile kudingeka ngomshini. Ingozi akuyona resin kangaka njengoba izingxenye esetshenziswa ukwenza okuqinile isimo s. Lapho eqina ngaphansi kwezimo lokushisa high kunethuba bokulahlekelwa viscosity impahla ukuthi kudalela eyengeziwe emsebenzini.

Yini engcono resin, epoxy noma i-polyester? Izibuyekezo bathi ezimweni eziningi, owokuqala isetshenziswa njengenhlangano ingcina, njengoba impahla yayo iphakeme kakhulu kunalokho indaba ka-polyester. Kwezinye izimo, umuntu enengqondo kakhudlwana ukusebenzisa i-polyester resin uhlobo, okuyinto, okokuqala, uyosindisa, futhi okwesibili, kube lula umsebenzi.

Izinzuzo usebenzisa poliefirki

Poliefirka izinhlanya izakhi ezinobuthi, kulula ukuyisebenzisa, kanye nobuchwepheshe ukusebenza ke akudingekile. Ukwakheka esetshenziswa lokunameka evele ahlukahlukene nge ukucutshungulwa okwalandela kusho, okwandisa amandla. Ngokwe izakhiwo kokokunamathisela epoxy poliefirka kakhulu eliphansi, futhi ulisebenzise ukuze gluing evele ezingenangqondo. Njengoba material for izinto zokuhlobisa asihambisani, njengoba has a izici ongaphakeme lokukhanda. Lapho ukuxuba ukubunjwa poliefirki isicelo esincane kulethe. Material Uqinisa ngokushesha, engakapheli amahora angu-2-3.

Ucezu okuphelele enwebekayo amelana eguqa. Minus umkhiqizo resin polyester kuyinto combustibility. Ungalokothi usebenzise i-polyester resin isihloko eyenziwe epoxy. Ukuze balungise umkhiqizo i material epoxy kungcono ukusebenzisa okufanayo.

Indlela efanele ukulungiselela ebusweni

Resin okumele asetshenziswe kuphela surface pre-ezilungiselelwe. Isinyathelo sokuqala Kwenziwa usebenzisa degreasing kuphela. Ngemva kokususa ebhuqwini amafutha ezipholisha inqubo wenziwa. Njengoba ebusweni impahla kanye lokukhuhla noma ithuluzi olukhethekile topsheet ekhishiwe. Khona-ke, inqubo yokususa uthuli. Ngemva kwalokho, isicelo kungenzeka ukuqala ingxenye ukusebenza.

zokuvimbela ingozi

Ukuze abangele ukulimala lapho esebenza inhlaka hardeners, kubalulekile ukuthatha izinyathelo esiphezulu. Ukwahluleka okuthobela nanoma imithetho elula kungaholela ekulimaleni kwesikhumba, ukusha noma wamaphaphu umsebenzi thuthuva uma usebenza ne epoxy noma i-polyester inhlaka. Izici nokuphepha lapho ukusebenza amakhemikhali:

• Ungasebenzisi izitsha senzelwe ukupheka.
• Zonke manipulations kumele kwenziwe izingubo akhethekile amagilavu. Ngaphambi abasebenza lo muthi ingalo kumele usetshenziswe. Ezipholisha imikhiqizo siphelile wenziwa ngomshini futhi izibuko ezikhethekile.
• Endabeni resin ehlela phezu kwesikhumba ke kufanele wageza ngensipho ngaphandle kokulibala noma utshwala okuhlanzekile.

Izikhundla yezingxenye epoxy kufanele kwenziwe endaweni kahle umoya.
