Ngaba i-melamine plywood inokupeyintwa okanye icocwe?

Umbuzo wokuba ingaba i-melamine plywood inokupeyintwa okanye iphuculwe yenye ehlala ivela phakathi kweengcali kunye nabathandi be-DIY. I-Melamine plywood, imveliso eyenziwe ngamaplanga enesigqubuthelo esikhuselayo se-melamine resin, inika ingqalelo ekhethekileyo xa isiza kuhlengahlengiso lomphezulu. Ngelixa i-melamine yokwambathisa yenzelwe ukubonelela ngokuqina, ukumelana nokufuma, kukho iindlela ezithile kunye namalungiselelo afunekayo ukupeyinta okuyimpumelelo okanye ukucocwa kwesi sixhobo. Ukuqonda ezi ndlela kubalulekile ekufumaneni iziphumo ezizezona zilungileyo ngelixa ugcina izibonelelo zendalo zemathiriyeli.

Ubuchwephesha bokuLungisa uMphezulu wokuguqulwa kweMelamine Plywood

Ukuqonda iMelamine Surface Structure

Ubume obukhethekileyo bomphezulu we-melamine plywood budlala indima ebalulekileyo kuyo nayiphi na iprojekthi yokucokisa. Umaleko we-melamine uquka intlaka ye-thermosetting eyenza umphezulu oqinileyo, ongeyo-porous ngokusebenzisa inkqubo yokunyanga ubushushu. Olu phawu lomphezulu lwenza ukuba iindlela zokupeyinta zesintu zibe ngumngeni, njengoko iiprimers eziqhelekileyo kunye neepeyinti zisenokungabambeleli ngokufanelekileyo kwi-melamine egudileyo, engenazimbobo. Ukuqonda i-molecular structure ye-melamine resin inceda ekukhetheni iindlela ezifanelekileyo zokulungiselela umphezulu kunye nezixhobo. Umaleko we-melamine uqhelekile ukusuka kwi-0.2mm ukuya kwi-0.5mm ubukhulu kwaye ubotshelelwe ngokusisigxina kwi-plywood substrate ngokusebenzisa i-high-pressure lamination, ukudala umphezulu ochasayo ukufuma, imikrwelo, kunye neekhemikhali eziqhelekileyo zasekhaya.

Iindlela zokuLungisa uMphezulu woBuchule

Ulungiselelo lobuchwephesha lwe i-melamine plywood imiphezulu ifuna ubuchule obuthile kunye nezixhobo zokuqinisekisa ukunamathela kwepeyinti ngokufanelekileyo. Isinyathelo sokuqala sibandakanya ukucocwa ngokucokisekileyo usebenzisa i-agent agent eyenzelwe ngokukodwa i-melamine surfaces, ukususa nayiphi na ioli, i-wax, okanye i-contaminants enokuphazamisa ukunamathela. Ukulandela ukucoca, umphezulu kufuneka uhlanjululwe ngokukhawuleza usebenzisa i-sandpaper ye-grit-grit (220-320 grit) ukwenza i-micro-texture ekhuthaza ukunamathela kwepeyinti. Ingqwalasela ekhethekileyo kufuneka ihlawulwe ekugcineni uxinzelelo oluhambelanayo ngexesha lesanti ukuphepha ukudala iindawo ezingalinganiyo okanye ukususa ngokupheleleyo i-melamine layer. Abalungiseleli abaqeqeshiweyo bahlala besebenzisa iisanti ze-orbital ezineenkqubo zokuqokelela uthuli ukuqinisekisa ukulungiswa okufanayo komphezulu ngelixa kuncitshiswa amasuntswana ahamba emoyeni.

I-Chemical Etching kunye ne-Bonding Solutions

Iindlela zokulungiselela iikhemikhali ziye zaphucuka ngakumbi kumphezulu we-melamine plywood. Ii-primers zokudibanisa zanamhlanje kunye nezisombululo ze-etching zenzelwe ngokukodwa ukudala iibhondi zeekhemikhali ezinomgangatho we-melamine. Ezi zisombululo zihlala ziqulathe iipholima ezikhethekileyo ezinokungena kwaye zihlangane kunye ne-melamine resin ngelixa zibonelela ngomphezulu ofanelekileyo kwiileya zepeyinti ezilandelayo. Ukusetyenziswa kwezi zisombululo zeekhemikhali kufuneka kuchaneke, kuqwalaselwe ngokucokisekileyo kwiimeko zeqondo lokushisa kunye nomswakama ngexesha lokusetyenziswa. Abaninzi abahlaziyiweyo beengcali basebenzisa inkqubo yokulungiswa kweekhemikhali ezinamanyathelo amabini: okokuqala sebenzisa isisombululo sokudibanisa ukuguqula i-chemical chemistry, elandelwa yi-primer yokudibanisa eyenza isiseko esiqinileyo sokugqoka okokugqibela.

Ubuchwephesha bokuPeyinta obuPhezulu beMelamine Plywood

UkuKhethwa kwePeyinti eKhethekileyo kunye neSicelo

Ukukhethwa kweemveliso zepeyinti ezifanelekileyo kubalulekile xa usebenza nge-melamine plywood surface. Ipeyinti ye-acrylic ene-urethane-modified high-adhesion ibonise iziphumo ezigqwesileyo kwiindawo ezilungiselelwe kakuhle ze-melamine. Ezi peyinti zenziwe ngee-resin ezikhethekileyo ezikhuthaza ukunamathela kwiindawo ezingenayo i-porous ngelixa zigcina ukuguquguquka kokuthintela ukukrazula okanye ukukhupha. Ubuchule bokufaka isicelo kufuneka balawulwe ngononophelo, kunye needyasi ezicekethekileyo ezisetyenziswayo kusetyenziswa iinkqubo zokutshiza zeHVLP (High Volume Low Pressure) okanye iirola ezinogwebu ezisemgangathweni. Iidyasi ezininzi ezicekethekileyo zikhethwa ngaphezu kweedyasi ezishinyeneyo ezimbalwa ukuthintela ukubaleka kunye nokuqinisekisa ukunyangwa ngokufanelekileyo. Ulawulo lobushushu kunye nokufuma ngexesha lokufaka isicelo kunye nokunyanga kubalulekile ukuze kuphunyezwe iziphumo ezilungileyo.

Iinkqubo zokugquma iiNgqungquthela ezininzi

Abahlaziyi bobuchwephesha bahlala besebenzisa iinkqubo zokugquma ezinomaleko amaninzi xa besebenza nazo i-melamine plywood. Le ndlela ngokuqhelekileyo iqala nge-primer ekhethekileyo yokudibanisa, ilandelwa yiidyasi zokwakha eziphakathi, kunye nokugqiba ngeengubo eziphezulu zokukhusela. Uluhlu ngalunye lusebenza ngenjongo ethile: i-primer iqinisekisa ukunamathela, iidyasi zokwakha zibonelela ngobunzulu kwaye zifihle ukungafezeki kwendawo, kunye neengubo eziphezulu zinika ukhuseleko kunye nokubonakala kokugqibela okufunwayo. Ixesha eliphakathi kokufakwa kwedyasi kufuneka libekwe esweni ngononophelo, njengoko ukuncamathela okufanelekileyo phakathi kwedyasi kuxhomekeke ekusebenziseni iidyasi ezilandelayo ngaphakathi kweefestile ezithile zokuhombisa. Iimeko zokusingqongileyo kufuneka zilawulwe kuyo yonke inkqubo yokugquma ukuze kuqinisekiswe ukubunjwa kwefilimu efanelekileyo kunye nokunyanga.

Ulawulo loMgangatho kunye neendlela zoVavanyo

Amanyathelo okulawula umgangatho ayimfuneko xa upeyinta i-melamine plywood ukuqinisekisa ukuqina kwexesha elide. Abahlaziyi bobuchwephesha basebenzisa iindlela ezahlukeneyo zovavanyo kuyo yonke inkqubo yokugquma, kubandakanywa uvavanyo lokuncamathela, imilinganiselo yobukhulu, kunye nokuqinisekisa inqanaba leglosi. Uvavanyo lwe-adhesion cross-hatch lubaluleke kakhulu kwaye kufuneka lwenziwe kwiipaneli zovavanyo ngaphambi kokuba kuqhutywe isicelo esipheleleyo. Uvavanyo lokusingqongileyo, kubandakanywa ukumelana nokufuma kunye nokuhamba ngebhayisikile lobushushu, kunceda ukuqinisekisa ukuqina kwenkqubo yokugquma. Amaxwebhu eemeko zesicelo, imilinganiselo yokwambathisa, kunye neziphumo zovavanyo zibonelela ngolwazi oluxabisekileyo lwesalathiso sexesha elizayo kunye nokuqinisekiswa komgangatho.

ULondolozo lwexesha elide kunye neziSombululo zokuKhathalela

IziCwangciso zokuThintela zokuLondoloza

Ukugcina ipeyinti yepeyinti ye-melamine plywood kufuna izicwangciso zokunyamekela ezikhethekileyo zokuqinisekisa ukuqina kwexesha elide. Ukucoca rhoqo kufuneka kwenziwe kusetyenziswa izicoci ze-pH-neutral ezilungiselelwe ngokukodwa iindawo ezipeyintiweyo. Gwema izinto zokucoca ezinqabileyo okanye izicoci zeekhemikhali ezinokonakalisa inkqubo yokugquma. Sebenzisa ishedyuli yokuhlola rhoqo ukuchonga naziphi na iimpawu zokuqala zokuguga okanye ukonakala, ngakumbi kwiindawo ezinabantu abaninzi betrafikhi okanye iindawo ezivezwe kukufuma. Iinkqubo zogcino lobuchwephesha zihlala zibandakanya uvandlakanyo lwamaxesha ngamaxesha kunye neenkqubo zokucofa ukulungisa umonakalo omncinci ngaphambi kokuba ukhokelele kwimiba ebalulekileyo.

Ukulungisa ubuChwephesha kunye nezisombululo

Xa kwenzeka umonakalo ukupeyintwa i-melamine plywood umphezulu, iindlela ezifanelekileyo zokulungisa ziyimfuneko ukugcina ukubonakala kunye nokukhusela. Imikrwelo emincinci okanye i-scuffs inokujongwa rhoqo kusetyenziswa iimveliso ezikhethekileyo zokucofa eziyilelwe umphezulu opeyintiweyo. Umonakalo obaluleke ngakumbi unokufuna ukulungiswa kwendawo usebenzisa inkqubo yokwaleka yokuqala. Iindawo zokulungisa kufuneka zifakwe iintsiba ngononophelo kwiindawo ezijikelezileyo ukugcina inkangeleko efanayo. Iingcali zokulungisa zihlala zisebenzisa ubuchule obukhethekileyo obufana nokudibanisa umbala kunye nokuveliswa kwakhona kwe-texture ukuqinisekisa ukuba ukulungiswa kuxutywa ngaphandle komthungo kunye nokugqitywa kokuqala.

UKhuseleko loMphezulu kunye neendlela zokuPhucula

Ukukhuselwa kwexesha elide leepeyintiweyo ze-melamine plywood kudla ngokubandakanya amanyathelo ongezelelweyo okukhusela. Izaleko ezicacileyo ezikhuselayo zinokufakwa phezu kwemiphezulu epeyintiweyo ukunika ukuqina okuphuculweyo kunye nokugcinwa lula. Ezi zogquma zingabandakanya i-UV inhibitors ukuthintela ukufiphala kunye nezongezo ezikhethekileyo zokuphucula ukuxhathisa kokukrwempa. Iindlela zokukhusela umphezulu kufuneka zikhethwe ngokusekelwe kwindawo ethile yesicelo kunye neemfuno zokusebenza.
