Umenzeli we-epoxy we-epoxy yinto yamakhemikhali esetshenziselwa ukwelaphaama-epoxy resinsNgokuphendula ngamakhemikhali ngamaqembu e-epoxy e-epoxy resin ukwakha isakhiwo esixhumeke ngokuqondile, ngaleyo ndlela enza i-epoxy ihlala kabusha okuqinile, okuqinile.
Indima eyinhloko yama-echents e-epoxy aphula ukuthuthukisa ubulukhuni, ukumelana ne-abrasion, kanye nokumelana kwamakhemikhali kwama-epoxy resins, kubenza babe nezinto ezihlala njalo futhi ezihlala isikhathi eside, okuyingxenye ehlanganisiwe ye-epoxy ecubuziwe ama-epoxy ashukunyiswa. Le ndatshana ihlanganyela indlela yokukhetha i-ejenti ye-epoxy-arinta efanelekile ngokusekelwe ezicini ezihlukile:
Ngokuya ngemibandela yokulapha
- Ukwelapha amazinga okushisa ekamelo: Uma kushelela ngokushesha emazingeni okushisa asekamelweni kuyadingeka, ama-ejenti aphilayo alandelana anjenge-ethylediamine ne-diethylenetriamine angakhethwa; Uma ijubane lokulapha alidingeki ukuba liphezulu, futhi ligxile ngesikhathi sokusebenza, ama-polyamide aphula ama-ejenti angakhethwa.
- Ukuvuselela Ukwelapha: Ukuze uthole ukumelana nokushisa okuphezulu kanye nezakhiwo zemishini, ama-ejenti we-amoratic amoring arading, njenge diadinodiphhenylsulfone (DDS), njll., Ingasetshenziswa; Ukuze uthole ukwelashwa okushisa okusheshayo okusheshayo, ama-aments aguquguqukayo we-Antine ane-accelerators angabhekwa.
- Ukwelashwa ngaphansi kwemibandela ekhethekile: ngokwelapha endaweni enomswakama, i-ejenti yokwelapha elaphayela elaphayo; Ngohlelo lokupheka olukhanyayo, umenzeli welapha ngePhothiinitor kanye ne-epoxy acrylate kungakhethwa.
Ngokwezidingo zokusebenza
- Izakhiwo zemishini: Uma kudingeka ubunzima obuphezulu namandla aphezulu, ama-anhydrideredrideredride welajenti angakhethwa; Uma ukuguquguquka okuhle nokumelana nomthelela kuyadingeka, ama-ejenti okulashwa okuhambisana ne-polysulfide rubber efanelekile.
- Ukumelana kwamakhemikhali: Izidingo eziphakeme ku-acid, alkali, kanye nokumelana no-solvent,phenolic resinUmenzeli welapha noma i-Agent eguquguqukayo ye-Amine welashwa ilungele kakhulu.
- Ukuvikelwa kokushisa: Ukuze uthole izindawo ezishisa kakhulu, ezinjengaphezulu kwama-200 ℃, umenzeli we-silicone welapha noma umenzeli welapha ngesakhiwo se-polyaromatic.
Ngokwemvelo yokusebenzisa
- Imvelo yasendlini: Izidingo eziphakeme zokuvikelwa kwemvelo, umenzeli we-epoxy osuselwa emanzini noma umenzeli ophansi we-Aliphatic Amine we-ament efanelekile.
- Imvelo yangaphandle: Ukumelana kwesimo sezulu okuhle kuyadingeka, ama-Agents aphulukayo a-Amine ane-Amening anokumelana okuhle kwe-UV afaneleke kakhulu.
- Izindawo ezikhethekile: Ezindaweni ezinezidingo zokuhlanzeka eziphakeme njengokudla nomuthi, ama-ejenti we-epoxy angewona anobuthi noma aphansi anobuthi abanjenge-polyamide akhethiwe ama-polyamide afanele afanele akhethwe.
Cabanga ngezidingo zenqubo
- Isikhathi sokusebenza: Isikhathi sokusebenza isikhathi eside, khetha i-ejenti ye-latent yelapha, efana ne-daticyandiamide, njll. Ukusebenza okufushane kanye nesikhathi sokwelapha, khetha i-agering ament esheshayo, khetha i-Ageng esheshayo ye-Amiphatic Amine Agent.
- Ukubukeka kokulapha
Kuhlangene nento yezindleko
- Ngaphansi kwesisekelo sokuhlangabezana nezidingo zokusebenza, qhathanisa inani kanye nomthamo wabameli abahlukile belapha. Intengo yama-Agents ajwayelekile we-Antine ariging aphansi, kanti amanye ama-ejenti akhethekile aphelayo afana nama-Fluarine-aqukethe ama-ejeli aqukethe ama-silicone aqukethe.
