I-Melamine Implation

Iphepha elifakwe imemela, sebenzisa iphepha eliphakeme eliphrintiwe eliphrintiwe, elifakwe nge-melamine resin, bese ligcotshwa zonke izinhlobo zamaphaneli asuselwa ngokhuni. Idlala umphumela omuhle kakhulu wokuhlobisa ebusweni bamaphaneli, futhi wenze ingaphezulu elingamelana nokushisa okuphezulu, ukugqoka - ukumelana nokungcoliswa komhlaba.

Njengamanje ukukhishwa okuvame ukwamukela i-sactation kabili. Iphepha lokuhlobisa okokuqala lifakwe nge-melamine resin ejwayelekile yokuthola ungqimba olujwayelekile, bese usebenzisa i-melamine resin ephezulu ye-melamine resin yesibili yokufakwa kwamaphepha amabili angafakwa kuzimfuneko zokugcina ze-melamine ezifakiwe, futhi zenze umkhiqizo ngokomnotho. Ukufakwa kokumiswa kunezidingo eziqinile ephepheni lomhlobiso eliphrintiwe ne-melamine resin. I-resin ngemuva kokushintshana kufanele ithole ukuguquguquka, okungavimba ukuqhekeka kwe-gretle crack. Ekukhiqizweni kwangempela, i-melamine resin nayo idinga ukwengeza izengezo ezahlukahlukene.

Ukuze uqinisekise ikhwalithi yephepha elifakiwe i-melamine, kufanele lisetshenziswe iphepha eliphakeme lokuhlobisa. Iphepha lokuhlobisa alinayo i-α pulp fielsi fiber, lenza kahle ngombala fade, futhi ingahlukaniswa kwamazinga okushisa aphezulu ka-180 c, kanye ne-opacity enhle. Kuma-izingalo ajwayelekile wephepha lokuhlobisa kufanele kube ngu-70 - 90g / ㎡, ngokubekezelela ± 2g / ㎡, okuqukethwe umswakama 2.5 - 7.5. Uma inani le-PH liphansi kakhulu, lingase libe nemibi ngemininingwane. Ukugwema ukuhlukana ngesikhathi sokucwilisa, ubude bekhefu elimanzi elide okungenani bungama-450m, kanye ne-300m elandelayo. Ukuthola ijubane elihle lokubika, iphepha lokuhlobisa kufanele libe nokumunca okuphezulu kakhulu ngokungena okusheshayo. Izidingo zokuphakama kwamanzi Ukubumbana kwephepha lokuhlobisa kufanele kube okulinganiselwe, kuphansi kakhulu kungathinta umphumela wokumangala ebusweni futhi kuphezulu kakhulu kuzonciphisa amandla okuhambisa kabusha.

Ukuguqulwa kwe-Resin kwe-Movie ikakhulukazi i-MF ne-UF, kanye nezithasiselo ezahlukahlukene. I-Pring Additive idlala indima ye-Catalyst ukusheshisa isikhathi sokwelapha ngesikhathi sokukhanya. Isengezo esimanzi ukunciphisa ukungezwani komhlaba kwe-resin, futhi kuthuthukise ikhono lokungena ephepheni lokuhlobisa ukuqinisekisa ukufana kokutholwa. Izengezo zokukhishwa zisetshenziselwa ukuvikela iphepha elifakwe kwi-spate yensimbi ngesikhathi se-lamination.defoaming additive isetshenziselwa ukugwema ama-bubble kubhavu we-resin athinta ukufana kokugcina. I-solvent ingamanzi noma i-ethanol, ixutshwe ukuze iguqule i-viscosity yokuthola imvume enhle ephepheni lokuhlobisa. Usebenzisa ubuchwepheshe obukhethekile be-glue ukwenza i-melamine formaldehyde resin kanye ne-urea flaordehyde resin, bese wengeza i-modifier nesitoreji, isengezo sezengezo, isengezo esingezansi, ukufakwa kwezengezo nezinye izithasiselo, kufakwe ezinye izithasiselo. Ngemuva kokuthunyelwa kabili, iphepha lokuhlobisa lidinga ukomiswa, lipholile futhi lisikwe osayizi abathile. Usayizi udinga ukuba ngu-10 - 30mm omkhulu kunamaphaneli ububanzi nobude. Ngokuvunywa, amashidi ephepha aqediwe afakiwe angafakwa uphawu ovalwe uphawu lwe-polyethylene ifilimu. Cishe amashidi angama-200 e-Bale nge-bale ngayinye, 10 amabhele ngalinye. Ukuze uqinisekise ukugcwala kwekhwalithi, iphepha elifakwe i-melamine kufanele ligcinwe esimweni esihle. Umswakama ohlobene endaweni yokugcina izimpahla uneminyaka engama-60 ± 5%, ukuze iphepha lingangeni noma likhiphe umswakama. Lokushisa kufanele kube ngu-20 - 25 ℃. Ukushisa okuphezulu kanye nomswakama ophezulu kwenza amashidi ephepha afakiwe athambile futhi anamathele. Kepha iphepha elifakiwe kulula ukuwaphula lapho izinga lokushisa liphansi kakhulu. Impilo eshalofini yephepha elifakwe cishe izinyanga ezi-3 uma igcinwe kahle. Ukuvimbela ukunamathela ngenxa yokumunca umswakama, sicela uphinde uphinde uphinde uphinde uvule kahle uma uvule kahle.

Okuqukethwe kwe-resin (resin eqinile okuhlobene nesisindo se-resin) kungu-130 - 150%. Okuqukethwe okuphansi kwe-resin kuletha amandla aphansi ephepheni, futhi kulula uku-Dimx. Okuqukethwe okufanele kwe-melamine kulungele ukugqama ekukhiqizeni nasezingeni. Lapho okuqukethwe kwe-resin kuphezulu kakhulu, kulula ukuqhekeka. Okuqukethwe kwento eguquguqukayo (ngo-160 ℃ ukomisa imizuzu eyi-10) kwakungu-6 - 7%.
