1. The Cal'adaAnd Didan aka kwatantaBtsakaninPolyurethaneAnd EpoxyRaddinin:

TheYawanci:

1)Polyurethane da resin epoxy sune sassa biyu, kuma kayan aiki da hanyoyin aiki iri ɗaya ne;

2)Dukansu suna da juriya mai kyau, babu fashewa, babu faduwa da sauran kaddarorin;

3)Dukansu suna da kaddarorin juriya na lalata ga mai ƙarfi acid, alkali, gishiri da abubuwan mai daban-daban;

4)Dukansu suna da kaddarorinƙura, hana ruwa, juriya na lalacewa, juriya mai nauyi, juriya mai tasiri da sauransu;

The Didan:

1)Polyurethane (PU)Polyphenylene diisocyanate da polyether polyol.Yana da haɗin kai kuma     warkewa a gaban mai kara kuzari triethylene diamine don samar da babban polymer.Idan aka kwatanta da resin epoxy, ya fi guba.

Polyurethane yana da halaye na mannewa mai kyau, rufi da juriya na yanayi.Ana iya canza taurin ta hanyar daidaita abun ciki na diisocyanate da polyether polyol, kuma ana iya amfani dashi a cikinmarufi na kayan aikin lantarki da na lantarki daban-daban.

2)Epoxy guduro gabaɗaya ya ƙunshi bisphenol A epoxy resin, wakili na warkarwa (amine ko acid anhydride), wakili na taimako, filler, da sauransu. Yana da dogon lokacin warkewa a cikin ɗaki kuma ana iya warkewa ta hanyar dumama.Bayan warkewa, yana da ƙarfin haɗin gwiwa da ƙarfi.Gabaɗaya, yana da girman gaske kuma ana iya yin shi a bayyane don ɓoye na'urorin lantarki da diodes.

Polyurethane yana da mafi kyawun juriya na yanayi, ba ya fashe a babban zafi da ƙananan zafi, kuma yana da ɗan tsada.

2.Amfani da polyurethane da epoxy resin:

1) Gudun polyurethane:

Gudun polyurethane abu ne na polymer tare da babban ƙarfi, juriya na hawaye, juriya da sauran halaye;

An yi amfani dashi azamanrollers, na'ura mai ɗaukar nauyi, hoses, sassa na mota, takalman takalma, roba fata, wayoyi da igiyoyi kumalikita wucin gadi gabobin, da sauransu;

Don kera samfuran filastik, samfuran roba na roba masu jure lalacewa, zaruruwan roba, m kuma m kumfa samfurori,adhesives da sutura, da dai sauransu;

Ana amfani da shi don karewa saman kayan itace daban-daban, kayan aikin sinadarai, kayan sadarwa da kayan aiki da hanyoyin sufuri daban-daban.

2)Epoxy resin: Hakanan za'a iya amfani dashi a cikin sutura, adhesives, kayan haɗin gwiwa, da sauransu.

Epoxy resin shafi wani nau'i ne mai ƙarfi mai ƙarfi, juriya da kyawawan bene, wanda ke da fa'idodin maras kyau, ƙaƙƙarfan rubutu, juriya mai kyau na sinadarai, rigakafin lalata, ƙura-hujja, ingantaccen kulawa da ƙarancin kulawa.

Daban-daban makircinsu za a iya tsara bisa ga abokin ciniki bukatun, kamar bakin ciki-Layer shafi, 1-5mm lokacin farin ciki kai matakin bene, anti-skid da lalacewa-resistant bene, turmi kasa, anti-a tsaye, anti-lalata bene, da dai sauransu.

Kayayyakin sun dace da wurare daban-daban, kamar taron karawa juna sani, dakunan kwamfuta, dakunan ajiya, dakunan gwaje-gwaje, dakunan kwana, dakunan tiyata, tarurrukan bita, da sauransu.

3. Tsohon topcoat ya dace da amfani da waje, yayin da na ƙarshe ya dace da amfani na cikin gida;

Babban rauni ko rashin amfani na karshen shine cewa yana jin tsoron hasken ultraviolet mai karfi, kuma zai juya launin rawaya a karkashin hasken ultraviolet mai karfi, wato, fade, amma ba zai rushe ba kuma ba zai shafi amfani ba;

Duk da haka, na farko ya inganta sosai a yanayin juriya fiye da na baya, musamman lokacin rawaya na tsohon ya fi tsayi fiye da na baya, don haka ana amfani da na farko don bukatun gine-gine na waje.
