I-Melamine yokungena

Iphepha le-Melamine elingenayo ePhezulu, sebenzisa iphepha le-Decor eliPhezulu le-Decor, efakwe i-melamine resin, emva koko yagungqa kuzo zonke iintlobo zeephaneli ezisesikweni. Idlala isiphumo esihle sokuhombisa kumphezulu weephaneli, kwaye senze umphezulu kubushushu obuphezulu, inxibe - Ukunganyangeki kunye nokuchasa.

Okwangoku ukubongoza kudla rhoqo, yamkela intetho kabini. Iphepha le-DECOR lifakwe kwi-melamin eqhelekileyo yokuqala ukufumana ungqimba olusisiseko, emva koko sebenzisa umgangatho ophezulu we-melamin kwi-vien yokungasebenziyo. Ukuvalwa kuneemfuno ezingqongqo kwiphepha le-Decor kunye ne-melamine resin. I-resin emva kokumohlwayo kufuneka ifumane bhetyebhetye, nto leyo enokuthintela umphezulu we-brittle rack. Kwimveliso yokwenyani, i-melamine retin kufuneka yongeze ezahlukeneyo zongezwa.

Ukuqinisekisa umgangatho wePhepha lePhepha leMelamine elingenamsebenzi, iphepha eliphezulu lehotele kufuneka lisetyenziswe. Iphepha lokuhlobisa alinawo i-piber ye-α, yenza kakuhle kwi-feade yombala, kwaye ichaze amaqondo obushushu aphezulu nge-180 c, kunye ne-opacity elungileyo. Kwigrafu yesiqhelo yephepha le-DECOR kufuneka ibe ngama-70 - 90g / ㎡, ngokunyamezela kwe-2g / ㎡, umxholo wokufuma 2.5 - Ixabiso le-EB 6.5 - 7.5. Ukuba ixabiso le-p liphantsi kakhulu, linokuzifumana ngexesha lokungena. Ukuthintela ikhefu ngexesha lokungena, ubude bekhefu le-ixesha elide lexesha elide buyi-450m, kunye ne-300m. Ukufumana isantya sokungangqinelani, iphepha le-DECOR kufuneka libe ne-ansing ephezulu kakhulu yokungena okukhululekileyo. IIMFUNO ZOKWENZA IIMFUNO ZOKUGQIBELA Ukugudisa kwephepha le-Decor kufuneka kube kumodareyitha, kakhulu kunokuchaphazela isiphumo somphezulu kumphezulu kwaye ukuphakama kakhulu kuya kunciphisa amandla okungena.

I-Reduntence Redin ikakhulu i-MF kunye ne-UF, kunye neendidi ezahlukeneyo zongezwa. Ukunyanga i-Isongere idlala indima ye-catalyst yokukhawulezisa ixesha lokunyanga ngesandla. Ukumanzisa i-Artication kukucutha uxinzelelo lomhlaba, kunye nokonyusa ubuchule bokukrazula kwiphepha lokuhombisa ukuqinisekisa ukufana nokungaboniswanga. Ukukhutshwa kwesongezelelo kusetyenziselwa ukuthintela iphepha elingenanto kwipleyiti yentsimbi ngexesha lokuhlambela. Isinyibilikisi ngamanzi okanye e-Ethanol, ebilisiwe ukuze uhlengahlengise i-viscofity ukufumana ukungcungcutheka okuhle kwiPhepha leDecor. Sebenzisa iteknoloji yeGlue ekhethekileyo ukwenza i-uplamine fomuldehyde kunye ne-urea ye-urealdehyde, kwaye emva koko wongeza i-modifier kwaye yongeza i-onrifier, i-storitive adrenies, yokukhupha i-ansortives, ilahlekile kwibhafu ye-resen. Emva kokungavavanywa kabini, iphepha lokuhlola kufuneka longe lome, lipholile kwaye lisike kubungakanani obuthile. Ubungakanani bufuna ukuba malunga ne-10 - I-30mm inkulu kunemigangatho yobubanzi nobude bezinto ezingenamsebenzi, kufuneka silandele imixholo enomxholo wenkqubo, i-70%, i-7%, yangaphambi kokunyanga i-65%. Ngemvume, amaphepha agqityiweyo ephepha anokugqobhoza anokupakishwa yifilimu yePolythyenene. Malunga namaphepha angama-200 ngeBale, iibhali ezili-10. Ukuze kuqinisekiswe ukuba i-lamoniation esemgangathweni, i-Melamine engathandekiyo igcinwe kwindawo elungileyo. I-themiding yesihlobo kwindawo yokugcina izinto ngama-60 ± 5%, ukuze iphepha aliyi kuthabathela umswakama. Iqondo lokushisa kufuneka libe yi-20 - 25 ℃. Ubushushu obuphezulu kunye nokufuma okuphezulu kwenza ukuba amaphepha amaphepha afakwe amaphepha athambile kwaye anamathele. Kodwa iphepha elivulekileyo kulula ukwaphula xa iqondo lobushushu liphantsi kakhulu. Ubomi beshelf yephepha elifakwe malunga neenyanga ezintathu ukuba zigcinwe kakuhle. Ukuthintela inamathelayo ngenxa yokufumana umswakama, nceda ulungise kwaye tywina kakuhle xa sele uvuliwe.

Umxholo we-resin (i-resin eqinileyo ihambelana nobunzima be-resin) yi-130 - i-150%. Umxholo we-resin ophantsi uzisa amandla asezantsi ephepheni, kwaye kulula ukuya kwi-dimex. Umxholo ofanelekileyo we-melamine ulungile ngenxa yokuvelisa kunye nomgangatho. Xa umxholo we-resin uphakame kakhulu, kulula ukuqhekeka. Umxholo wezinto eziguquguqukayo (nge-160 ℃ ukomisa imizuzu eli-10) yayiyi-6 - 7%.
