I-epoxy kufuneka isebenzise i-resin kunye ne-hardener chemistry efanelekileyo kwilitye elinombala, kunye nokusebenza okuqinisekisiweyo okuphantsi kwe-yellowing phantsi kwenkqubo ejoliswe kuyo kunye neemeko zenkonzo.

Okwesibini kukulawula ukungena emzimbeni.

I-resin kufuneka ingene kwiintanda kunye neepores ngokwaneleyo ukuze zomeleze ngaphandle kokusasazeka ukuya kuthi ga kwibhastile kangangokuba idale iihalos ezimnyama okanye iindawo ezikhangeleka zimanzi.

Ukuba ibhastile liqinile kwaye lixinene, inkqubo yokungena emthubi kakhulu inokuba lelona cala lilungileyo.

Ukuba ibhastile lithambile kwaye liyafunxa, beka phambili ukusebenza okungangcolisi kunye nokungena okulawulwayo.

Ukuba ufakelo luya kufumana i-UV okanye ubushushu obucacileyo, musa ukuthembela kuphela ekucaceni kokuqala. Cela ulwazi olufanelekileyo lokuguga okanye wenze uvavanyo lokuthelekisa.

Kwaye ukuba ukulungiswa kubonakala kumnyama kodwa i-epoxy ngokwayo ihlala icacile, phanda ukungena kunye ne-optics yamatye ngaphambi kokuba utyhole i-polymer yellowing.

Imibuzo Ebuzwa Rhoqo malunga ne-Epoxy Yellowing kwi-White Marble

1. Kutheni i-epoxy ijika ibe tyheli kwibhastile elimhlophe?

I-epoxy inokuba tyheli ngenxa yokuguga kwepolymer ehambelana nokuvezwa kwe-UV, ubushushu, i-oxidation, i-resin kunye nekhemistri eqinile, kunye nezinye iimeko zokusingqongileyo. Ibhastile elimhlophe lenza utshintsho lombala oluncinci lubonakale kakhulu. Nangona kunjalo, ayizizo zonke iindawo ezimnyama okanye eziguqulwe umbala ziyinyani ye-epoxy yellowing; Ukungena ngokugqithisileyo, ukungcolisa, kunye ne-optical shadowing kunokudala iziphene ezijongeka ngokufanayo.

2. Ngaba kukho i-epoxy resin engekho tyheli ngokupheleleyo?

Iimveliso zorhwebo zinokuchazwa njengezingekho tyheli okanye zibe tyheli kakhulu, kodwa abathengi bafanele batolike le migaqo njengozinzo oluphuculweyo lombala phantsi kweemeko ezichaziweyo kunobungqina bokuba akukho tshintsho luya kuze lwenzeke. Kwiiprojekthi ezibango, thelekisa ukusebenza kokuguga kwaye uvavanye inkqubo epheleleyo ye-resin-hardener kweyona marble emhlophe.

3. Yeyiphi i-epoxy ekufuneka isetyenziswe kwibhastile eliqinileyo elimhlophe?

Ibhastile eliqinileyo eliqinileyo lixhamlwa ngokubanzi kwi-epoxy emthubi kakhulu-esezantsi kakhulu ngokungena okulawulwayo, ukucaca okuphezulu, kunye nokuhamba okwaneleyo ukomeleza iintanda ezicolekileyo. Inkqubo yeVeropoxy’s 5090 / D30M-BS ibekwe ngokukodwa kwilitye lebhastile eliqinileyo kwaye idwelisa umthubi ophantsi kakhulu, 400–600 CPS viscosity, umlinganiselo we-100:30, kwaye malunga nemizuzu engama-80 yokunyanga malunga ne-24°C.

4. Kutheni i-epoxy ecacileyo idala uphawu olumnyama kwibhastile elimhlophe elithambileyo?

Ingxaki inokuba kukungena ngokugqithisileyo kunokuba ibe yikhemikhali yokutyheli. I-resin inokutshintsha indlela ukukhanya okuhamba ngayo kwi-marble e-porous, idala i-halo ekhangeleka imanzi okanye imnyama ejikeleze indawo ephathwayo. Kwibhastile elimhlophe elithambileyo, sebenzisa inkqubo eyenzelwe ukungena okulawulwayo kunye nokuziphatha okungangcolisi.

5. Umzi-mveliso kufuneka uvavanye njani i-epoxy phambi kokuba uyisebenzise kwibhastile elimhlophe?

Vavanya i-epoxy kwi-slabs yemveliso emeleyo kumaqondo obushushu obuyinyani basefektri. Rekhoda umlinganiselo wokuxuba kunye nobungakanani besicelo, uhlole imida yokungena, vumela ukunyanga okupheleleyo, upholise i-slab usebenzisa inkqubo eqhelekileyo, kwaye uthelekise umbala, ukukhanya, ithoni ephuzi, ithunzi, ukubonakala kokulungisa, kunye neglosi. Kwiiprojekthi zexabiso eliphezulu, yongeza ubushushu obuthelekisekayo okanye uvavanyo lokuguga lwe-UV ngaphambi kokuvunywa okuninzi.
