Okwesibili ukulawula ukungena ngokomzimba.

I-resin kufanele ifake imifantu nezimbotshana ngokwanele ukuze iqine ngaphandle kokusabalala kuze kube manje emabula kangangokuthi idale ama-halo amnyama noma izindawo ezibukeka zimanzi.

Uma imabula iqinile futhi iminyene, uhlelo lokungena oluphuzi kakhulu lungaba isiqondiso esingcono.

Uma imabula ithambile futhi imunca, beka phambili ukusebenza okungangcolisi kanye nokungena okulawulwayo.

Uma ukufakwa kuzothola ukukhanya okukhulu kwe-UV noma ukushisa, unganciki kuphela ekucaciseni kwasekuqaleni. Cela ulwazi olufanele lokuguga noma wenze ukuhlola okuqhathanisayo.

Futhi uma ukulungisa kubukeka kumnyama kodwa i-epoxy ngokwayo ihlala icacile, phenya ukungena nokubona kwetshe ngaphambi kokusola ukuphuzi kwe-polymer.

Imibuzo Evame Ukubuzwa Mayelana Ne-Epoxy Yellowing Kumabula Emhlophe

1. Kungani i-epoxy iphenduka ibe phuzi emabula emhlophe?

I-epoxy ingaba phuzi ngenxa yokuguga kwe-polymer okuhlobene nokuchayeka kwe-UV, ukushisa, i-oxidation, i-resin ne-hardener chemistry, nezinye izimo zemvelo. Imabula emhlophe yenza izinguquko zombala ezincane zibonakale kakhulu. Nokho, akuzona zonke izindawo ezimnyama noma ezinemibala ephuzi e-epoxy; ukungena ngokweqile, ukungcolisa, kanye ne-optical shadowing kungadala amaphutha abukeka ngendlela efanayo.

2. Ingabe ikhona i-epoxy resin engaphuzi ngokuphelele?

Imikhiqizo yezentengiso ingase ichazwe njengengaphuzi noma iphuzi kakhulu, kodwa abathengi kufanele bahumushe la magama njengokusimama kombala okuthuthukisiwe ngaphansi kwezimo ezichaziwe kunobufakazi bokuthi alukho ushintsho olungake lwenzeke. Kumaphrojekthi afunayo, qhathanisa ukusebenza kokuguga futhi uhlole uhlelo oluphelele lwe-resin-hardener kumabula yangempela emhlophe.

3. Iyiphi i-epoxy okufanele isetshenziselwe imabula emhlophe eqinile?

Imabula emhlophe eqinile ngokuvamile izuza ku-epoxy ephuzi kakhulu enokungena okulawulwayo, ukucaca okuphezulu, nokugeleza okwanele ukuze kuqinise imifantu emihle. Uhlelo lweVeropoxy luka-5090 / D30M-BS lubekwe ngokukhethekile imabula emhlophe eqinile futhi lubala ukuphuzi okuphansi kakhulu, i-viscosity engu-400–600 CPS, isilinganiso esingu-100:30, kanye nokuphulukiswa okungaba yimizuzu engama-80 cishe ku-24°C.

4. Kungani i-epoxy ecacile yenza uphawu olumnyama emabula emhlophe ethambile?

Inkinga ingase ibe ukungena ngokweqile kunokuba kube ukuphuzi kwamakhemikhali. I-resin ingashintsha indlela ukukhanya okuhamba ngayo ngemabula enezimbotshana, idale i-halo ebukeka imanzi noma emnyama endaweni ephathwayo. Ngemabula emhlophe ethambile, sebenzisa isistimu edizayinelwe ukungena okulawulwayo nokuziphatha okungangcolisi.

5. Kufanele ihlole kanjani i-epoxy yasefekthri ngaphambi kokuyisebenzisa emabula emhlophe?

Hlola i-epoxy kuma-slabs okukhiqiza amele emazingeni okushisa emboni angokoqobo. Rekhoda isilinganiso sokuxuba kanye nenani lohlelo lokusebenza, hlola imingcele yokungena, vumela ukwelashwa okuphelele, pholisha i-slab usebenzisa inqubo evamile, futhi uqhathanise umbala, ukukhanya, ithoni ephuzi, ithunzi, ukubonakala kokulungisa, nokucwebezela. Kumaphrojekthi yenani eliphezulu, engeza ukushisa okuqhathanisayo noma ukuhlolwa kokuguga kwe-UV ngaphambi kokugunyazwa kwenqwaba.
