IBhodi Lamination

Melamine faced panel is also called prelaminated panel with a different color or texture. Iphepha elifakwe ku-Melamine lifakwe emaphaneli asuselwa ngokhuni njenge-MDF, i-Plywood Board, i-Plywood, ibhodi ye-block, bese livila ngokushisa okuphezulu kwengcindezi ephezulu. Indawo yephepha le-melamine ayigcini nje ngokuthuthukisa amandla wephaneli, ukuqina kanye nokuqina kobukhulu, kepha futhi kungenza ukuthi ingaphezulu layo linezinzuzo zokumelana nokugqoka, ukungcola okuphezulu, ukungcoliswa kwemvelo, ukuvikelwa kwemvelo, ezempilo kanye nokusebenza.

Inqubo ye-Prelamined Panels Inqubo: Ukulungiselela amaphaneli → Amaphaneli ahlanzekile Ngaphambi kokukhanyiswa, kufanele sikhethe amaphaneli asezingeni eliphakeme ngokhuni kanye nephepha elifakwe i-melamine, kuphela izinto ezifundwayo ezifanelekile ezingakhethwa ukuze kukhiqizwe.

Impregnated paper requires the resin content is 130-150%, volatile content 6-7%, the pre curing degree ≦ 65%. Melamine impregnated paper should be in good condition, and packed with film to prevent the absorption of moisture. Kungcono ukuzala ngaphambi kwezinyanga ezi-3 ngemuva kokukhiqizwa, futhi kugcinwe esitolo esiseduze nomswakama ongeyena umswakama ka-60 + 5%, izinga lokushisa 20 - 25 ℃. The most popular panels are fiber board, particle board and plywood. Quality panels requirements: 1) double side sanding, the surface is smooth and bright, uniform thickness, thickness tolerance 0.2mm. 2) board edges are intact, not eating, no oil or water pollution. 3) moisture content of the board is controlled in the range of 6-10%.

Ngesikhathi senqubo yokuqashisa, kufanele silandele ngokuqinile ukucaciswa kobuchwepheshe, lawula izinga lokushisa elicindezelayo 140 - 190 ℃, ingcindezi yeyunithi 2.0 - 3.0MPA, icindezela isikhathi 25 - 50s. Ukucindezela izinga lokushisa, ingcindezi kanye nesikhathi sokucindezela kuncike kakhulu futhi kuvinjelwe ngokulinganayo, okungashintshwa ngokuya ngothando lwangempela lwabezindaba. Hot temperature is mainly to accelerate the chemical reaction of melamine resin, the most workable temperature is 140-190℃. Izinga lokushisa eliphakeme lingasiza ukuyeka ngemuva kokucindezela, futhi linciphise isikhathi sokucindezela, sithuthukise ukusebenza kahle kokukhiqiza.kodwa izinga lokushisa eliphakeme kakhulu lizokwenza ukuphinda kwenze ama-resin ngaphambi kokugeleza komfaniswano. Ingcindezi efanelekile ingaqinisekisa ukunamathela okuhle phakathi kwamabhodi kanye nephepha elifakiwe, ingcindezi esebenzayo ngokuvamile i-2.0 - 3.0MPA, ethandeka ekunciphiseni i-resin incibilike futhi iqinise, yakha indawo evaliwe neCompact. Ngaphansi kwesisekelo sekhwalithi enhle, ingcindezi ephansi kufanele isetshenziselwe ukwandisa impilo yenkonzo yemishini, futhi inenzuzo ekwakhekeni kwangaphakathi kwezingulube. But too low pressure will affect the adhesive strength and resin flow capacity. According to the different kinds of panels, the unit pressure need to be adjusted by buffer mat. The pressing time depends on the curing speed of resin in the impregnated paper and the pressing temperature, and 25-50s is the best. Isikhathi eside kakhulu sizodala ukuphila ngokweqile futhi silahlekelwe ukunwebeka, okuholela ekuqhekekeni noma inhloso yangaphakathi futhi kule nqubo elandelayo kuzoletha ukuqhekeka, ukugoqa. Time is too short, resin curing is not sufficient, make the boards sticky and affect the product durability.

Ukuhlaziywa kwezinkinga zekhwalithi ezijwayelekile kanye nezimbangela zamaphaneli athunyelwayo:

1) White spot, the main reason is the bad flow of in impregnated paper or less resin content. Izizathu zingaba: Akukho sandwing ebhodini elingaphezulu noma i-sanding hhayi umfaniswano, lapho ubuntu bungaphansi, bese uletha ukugeleza okuningana kwe-resin kule ndawo, bese kubangela ukugeleza okuthe xaxa, bese kubangela ukugeleza okumhlophe, bese kubangela ukugeleza kwensimbi okumhlophe, bese kubangela ukugeleza kwensimbi I-Spot.Mat Damarages, okuholela ekushiseni okuhlukile kwesikhundla esihlukile sepuleti lensimbi futhi kubangele indawo emhlophe ye-Spot.Inye isikhathi se-melamine efakwe ephepheni, i-High Preding degree, izothinta ukuhamba kwe-resin futhi ibangele ukugeleza okumhlophe. Too high resin content on melamine impregnated paper may bring bubbles during lamination and cause white spot.

2) I-WET Spot, isho umkhondo we-wave emabhodini amabhodi ama-prelisamined, futhi kukhona iziphambeko ezibonakalayo.Izizathu eziphakeme zephepha elinamanzi noma i-Shot Presed Spot izoba ne-Spot Spop.Hight

3) Sticky with steel plate refers to the melamine board stick with steel plate during lamination. Kunamathele kancane kuzothonya ikhwalithi ephezulu, kunamathele kakhulu kuzothinta ukukhiqizwa.Izizathu ze-resin ephezulu noma okuqukethwe kwensimbi engcolile, okuholela ekukhishweni okubi. Okuqukethwe okuphezulu kwamapheki ephepheni, izinga lokucindezela eliphansi kanye nesikhathi esifushane sokucindezela, okuholela e-resin bekungaphuluki ngokuphelele ekukhululweni okubi. Damages on mat resulting in not uniform temperature on steel plate brings bad release. High moisture content or high PH value on boards brings bad release.

4) Ama-Bubble, izizathu eziphambili: izinga lokushisa eliphakeme kakhulu lokucindezela, isikhathi eside sokucindezela kuletha ama-demix noma ama-bubble. Umswakama ophakeme kakhulu noma omncane kakhulu wamabhodi angaletha ama-demix noma ama-bubble ngesikhathi sokukhanya kwe-Amin.tooni okuholela ku-demix noma ama-bubble.

5) Bow warping refers to surface uneven surface or cutting bending because of bad uniformity of inside intention strength. Izizathu eziphambili yilezi: Umehluko omkhulu ekucindezelweni kwamazinga okushisa phakathi kwensimbi ephezulu nephansi yensimbi kubangela isivinini esihlukile sokwelapha futhi uholele ekushayweni kwe-warping. Iphepha elihlukile elifakwe kwi-melamine kuwo womabili lawo mahle lingadala ukugoba ngemuva kokuvinjelwa.

Ngamafuphi, kufanele sikhethe iphepha nezinkuni ezinhle kakhulu ezifakwe ngaphakathi njengephaneli esekelwe njengezinto zokwakha, futhi sandisa inqubo yokukhiqiza njengemishini yokukhiqiza ehlukile, ngaphansi kokusebenza kwabantu kanye nokuhlola, okungaqinisekisa ukuqina kwekhwalithi yomkhiqizo.
