Uyenza njani iMelamine plywood?

I-Melamine plywood yimveliso yokhuni enobunjineli ehlala ixesha elide edibanisa amandla okwakhiwa kweplywood kunye neempawu zokuhombisa kunye nokukhusela i-melamine resin. Inkqubo yokuvelisa ibandakanya ukubeka ngokucokisekileyo i-veneers yomthi kunye ne-adhesives kwaye uyigqume nge-melamine resin phantsi kweemeko ezithile zokushisa kunye noxinzelelo. Esi sikhokelo sibanzi siphonononga inkqubo entsonkothileyo yokwenziwa kwe-melamine plywood, ukusuka ekukhethweni kwezinto ezikrwada ukuya kulawulo lokugqibela lomgangatho, iqinisekisa ukuveliswa kwemveliso enganyangekiyo kwaye ebukekayo ifanelekile kwizicelo ezahlukeneyo kwifanitshala kunye noyilo lwangaphakathi.

IMathiriyeli ekrwada kunye neNkqubo yokuLungisa

Ukukhethwa kweeVeneers zeenkuni ezisemgangathweni

Isiseko seplywood ephezulu ye-melamine siqala ngokukhetha ngokucophelela i-veneer yomthi. Inkqubo iqala ngokukhetha umthi oqinileyo okumgangatho ophezulu okanye iintlobo ze-softwood, ezibandakanya i-birch, ipayini, okanye ipoplar. Ezi ntlobo zemithi zikhethwa ngokusekelwe kwipatheni yazo yeenkozo, ukuxinana, kunye nomxholo wokufuma, ofanele ukuba phakathi kwe-8-12%. Iiveneers zijongwa ngokungqongqo komgangatho wolawulo lweziphene ezinje ngamaqhina, ukwaphuka, okanye ukujika kombala. Iimitha zokufuma eziphezulu kunye neenkqubo zokuhlola ezibonakalayo ziqeshwe ukuqinisekisa ukuba i-veneer nganye ihlangabezana nemigangatho engqongqo yobulunga. Ubukhulu bezi veneers ngokuqhelekileyo buqala kwi-1.5mm ukuya kwi-3.0mm, kuxhomekeke kwiinkcukacha zemveliso yokugqibela kunye nokusetyenziswa okujoliswe kuyo kweplywood ye-melamine.

Ukulungiswa kwe-Melamine Resin

Ukulungiswa kwe-melamine resin linyathelo elibalulekileyo elichaphazela ngokuthe ngqo ukuqina kunye nenkangeleko yemveliso yokugqibela. Inkqubo iqala nge-synthesis ye-melamine-formaldehyde resin phantsi kweemeko ezilawulwayo. Ukwakhiwa kwe-resin ngokuqhelekileyo kubandakanya i-melamine powder, isisombululo se-formaldehyde, kunye ne-catalysts kwi-ratios echanekileyo. Ukulawula ubushushu ngexesha lokulungiselela kubalulekile, ngokuqhelekileyo kugcinwa phakathi kwe-60-70 ° C. I-viscosity ye-resin kufuneka ihlolwe ngokucophelela kwaye ihlengahlengiswe ukuqinisekisa ukungena ngokufanelekileyo kwindawo yokhuni. Izongezo ezongezelelweyo ezinje nge-hardeners, i-UV stabilizers, kunye ne-pigment yemibala inokudityaniswa ukuze kuphuculwe iipropathi ezithile zokugqibela. i-melamine plywood imveliso.

ULungiselelo lweNkqubo yokuncamathelisa

Inkqubo yokuncamathelisa isebenza njengesixhobo esibophelelayo esibalulekileyo phakathi kwamaleko omthi kwimveliso ye-melamine plywood. Ukuqulunqwa okukhethekileyo ngokuqhelekileyo kubandakanya i-urea-formaldehyde okanye i-phenol-formaldehyde resins, idibaniswe ne-hardeners kunye ne-catalysts. Inkqubo yokuxuba idinga ulawulo oluchanekileyo lokushisa, ngokuqhelekileyo phakathi kwe-20-25 ° C, kunye neeparitha ezithile ze-viscosity zokuqinisekisa amandla afanelekileyo ebhondi. I-adhesive kufuneka ilungiswe ngokutsha ngaphambi kokufakwa kwesicelo, ngokuqwalasela ngokucophelela ubomi bembiza kunye nexesha lokusebenza. Amanyathelo okulawula umgangatho abandakanya ukuhlolwa kwe-viscosity rhoqo kunye neemvavanyo zamandla ebhondi ukuqinisekisa ukusebenza okuhambelanayo kuyo yonke inkqubo yokuvelisa.

Inkqubo yokuVelisa kunye neZixhobo

I-Hot Press Operation

Umsebenzi wokushicilela oshushu ubonisa isigaba esibalulekileyo sokwenziwa kwe-melamine plywood. Inkqubo isebenzisa oomatshini bokushicilela abashushu behydraulic abasebenza kumaqondo obushushu aphakathi kwe-140-160°C kunye noxinzelelo olusuka kwi-15-20 kg/cm². Umjikelo wokucinezela ngokuqhelekileyo unezigaba ezithathu: ucinezelo lokuqala, ixesha lokunyanga, kunye noxinzelelo. Ngexesha lokucinezela, i-melamine resin idlula i-polymerization, idala indawo enzima, ehlala ixesha elide. Iipleyiti zokushicilela kufuneka zigcine ukuhanjiswa okufanayo kobushushu ukuqinisekisa ukunyangwa okuhambelanayo kwibhodi yonke. Iinkqubo zolawulo ezintsonkothileyo zibeke iliso kwaye zilungelelanise uxinzelelo, ubushushu, kunye neeparamitha zexesha ukuze kuphuculwe inkqubo yokunyanga kunye nokuthintela iziphene ezinje nge-delamination okanye izitenxo zomhlaba.

Unyango loMphezulu kunye nokuQeda

Unyango lwakumphezulu luqala ngokusantiya ngononophelo kusetyenziswa iisanti zodidi lwemizi-mveliso ezinobungakanani obahlukeneyo begrit, eqhubela phambili ukusuka kuma-80 ukuya kuma-220 egrit. Inkqubo yesanti iqinisekisa ukuguda okuphezulu komphezulu wokusetyenziswa kwe-melamine. Emva kwesanti, iindawo zicocwa ukususa uthuli kunye nenkunkuma. Isicelo sokwaleka kwe-melamine sibandakanya ulawulo oluchanekileyo lobushushu kunye nesicelo soxinzelelo ukuze kuqinisekiswe ukubamba okufanelekileyo. Izixhobo eziphezulu zokugqiba, kubandakanywa imigca yokugqoka ezenzekelayo kunye neenkqubo zokunyanga i-UV, iqinisekisa umgangatho ohambelanayo womphezulu. Umphezulu ogqityiweyo ujongana nokulawulwa komgangatho womgangatho weglosi, ukumelana nokukrweleka, kunye nenkangeleko iyonke.

Ulawulo loMgangatho kunye noVavanyo

Ulawulo lomgangatho kwi i-melamine plywood imveliso ibandakanya iinkqubo ezininzi zokuvavanya kunye neendawo zokujonga.
