I-Melamine foam yinto esebenzayo eneempawu ezibalaseleyo zokunciphisa isandi kunye neempawu zokunciphisa ingxolo, kunye nokungalali kakuhle komlilo. Xa isetyenziselwa ukuthintela umlilo, inceda ekulawuleni ukudluliselwa kobushushu kunye nokudluliselwa kobushushu obukhanyayo ukuphucula ukhuseleko kunye nentuthuzelo. Iimpawu zayo zokwahlula isandi kunye nokungcangcazela zidala imeko-bume ezolileyo kumntu wonke. Kweli nqaku, siza kungena kwiinkcukacha ezithe vetshe malunga nokuba kutheni i-melamine foam ifanelekile kokubili ukuthintela ubushushu kunye nokugquma.
Yintoni i-melamine foam?
I-Melamine foam yinto egudileyo, eguquguqukayo, enoxinano oluphantsi, imathiriyeli ye-microcellular eyenziwe kwi-melamine resin, i-polymer ye-thermosetting eyenziwe nge-melamine kunye ne-formaldehyde. Ukwenza i-melamine foam, i-melamine resin ikhompawundi ifakwe ugwebu nge-agent evuthelayo kwaye iphiliswe. Isiphumo sisixhobo esinesakhiwo esikhethekileyo sesithathu-dimensional esibonakaliswe yinkqubo yokudibanisa kakhulu (iseli evulekileyo).
Iqondo eliphezulu lokudityaniswa kwe-cross-link kwi-foam ye-melamine yenza ukuba ikwazi ukumelana nokubanda kwaye izinzile ngakumbi kwi-thermal kune-foam zendabuko ezifana ne-polyethylene, i-polypropylene kunye ne-polyurethane, engaphantsi kwe-cross-link. Amagwebu e-melamine anokumelana nobushushu obuphezulu kakhulu (ukuya kuthi ga kwi +240°C) kunye nobushushu obuphantsi (ukuya kuthi ga kwi-180°C) ixesha elide ngelixa ligcina uzinzo kunye nokusebenza kwazo.
Imisebenzi kunye neempawu ze-melamine foam
Amaphepha e-foam e-Melamine abe lolona khetho lubalaseleyo kuluhlu olubanzi lwezisombululo ze-thermal kunye ne-acoustic insulation ngenxa yokusebenza kwazo okuhle kunye neepropathi. Umgangatho we-melamine uphezulu kakhulu xa kuthelekiswa nezinye izinto zokugquma. Ezinye zeempawu kunye neempawu ezichaza oku kugqunywa kweeseli ezivulekileyo kubandakanya:
-Ikhaphukhaphu
-Ingangeni kwidangatye
-Ukumelana namanzi -Igwebu leHydrophobic kuphela
-Ukwanda komlilo ophantsi, ukuveliswa komsi kunye netyhefu
-Kulula ukwenza ngokwezifiso
I-semi-rigid, kodwa ibuye ibe bhetyebhetye
1. Ubunzima
Ukusetyenziswa kwezixhobo zokugquma ukukhanya kubonelela ngeenzuzo ezininzi kwiintlobo ezahlukeneyo zezicelo. Banciphisa iindleko zemveliso kunye nexesha kwaye banikeze ukuguquguquka okukhulu. Ngobunzima obungaphantsi kwe-0.75 pounds nge-cubic foot (lb / ft3), i-melamine foam idla ngokuba yi-insulation yokuzikhethela xa ubunzima bezinto eziphathekayo bunokuba nefuthe elikhulu kwisicelo. Cinga nje nge-aerospace kunye nezicelo zomkhosi apho ubunzima bubaluleke kakhulu.
Ngenxa yobume beeseli ezivulekileyo, igwebu le-melamine likhaphukhaphu kune-thermal yendabuko kunye ne-acoustic insulation kwaye inokuhambelana ngokulula nokusebenza kwe-insulation engqindilili.
2. Ukusilela komlilo
Ngenxa yezizathu zokhuseleko, nakuphi na ukugquma kufuneka kunqandwe ngamadangatya. Emva kwayo yonke loo nto, oku kukusetyenziswa okuphambili kwe-insulation. Izinto ezithintela amadangatya zithintela ukusasazeka komlilo kwaye zikhusela izakhiwo kunye nezinye izicelo kumonakalo womlilo. Ikhompawundi yenitrogen kwi-foam ye-melamine ayinakutsha kwaye icinezela umsi, idibana ne-UL 94 imigangatho yokhuseleko lokutsha. Ichasa ukushisa okuphezulu ngaphandle kokunyibilika okanye ukwenza amaconsi avuthayo kwaye ifanelekile kwiindawo ezikhuselekileyo zomlilo kunye neemfuno eziphezulu.
3. Into evikela amanzi
Ngokwesiqhelo, i-melamine foam eqhelekileyo ayingeni manzi. Ke ngoko, kungcono ukubhenela kwi-hydrophobic melamine foams xa kusetyenziswa apho umngcipheko wokuvezwa emanzini kunye nokufuma uphezulu. Ii-Melamine foams, ezifana ne-hydrophobic melamine, zigqunywe nge-resin yokuthintela amanzi enyangwa kukukhanya kwe-UV, nto leyo eyenza ukuba zingangeni manzi. Ezinye iintlobo zifumana i-plasma vaporization ukuze zonyuse ukumelana kwamanzi. Ii-hydrophobic melamine foams zicetyiswa ngokukodwa kwi-acoustic kunye ne-thermal insulation kwiindawo ezifuna ukumelana nokufuma okugqithisileyo, ukusasazwa komlilo ophantsi, njl. Oku kunjalo, umzekelo, kwii-fuselages zeenqwelo-moya kunye neendonga, iipayipi ze-ECS kunye nezithuthi zamandla amatsha.
4. Ukusasazwa komlilo ophantsi, ukuveliswa komsi kunye netyhefu
Ngokuxhomekeke kuxinzelelo kunye neqondo lokushisa lokungena, umlilo okanye ilangatye lingasasazeka (ukusasaza) ngokuqhuba, ukudibanisa okanye i-radiation. Nokuba yeyiphi na indlela esetyenziswayo, ukusasazeka kwedangatye kunokonakalisa, kubangele umonakalo ongenakulungiseka nokudala iingozi ezininzi zokhuseleko. Ukugquma okufanelekileyo kunokunceda ukuthintela ukusasazeka komlilo kunye nokwandisa ukhuseleko. I-Melamine foam iyaziwa ngeempawu zayo zokusasazeka kwedangatye eliphantsi kwiindawo eziphezulu zokushisa kunye nokusetyenziswa. Ngokuchasene noko, xa ibonakaliswe kumaqondo obushushu aphezulu, iyatshisa, inciphisa ukunikezelwa kweoksijini kunye nokucotha ukusasazeka kwedangatye ukwenzela ukhuseleko olwandisiweyo.
5. Ngokulula Customizable
Ukugquma okufanelekileyo kufuneka kube lula ukuba kube lula ukuhambelana neentlobo ezahlukeneyo zokufakwa kwe-insulation. I-Melamine foam yenye yezona zinto zikhethwayo zokugquma. Inokwakheka kweeseli ezivulekileyo eziphucula ukuguquguquka kunye nokwenza kube lula ukusika. Ifumaneka ngeemilo ezahlukeneyo, imibala, kunye nobukhulu ukuhlangabezana neenkcukacha zabasebenzisi. Ukongeza, unokugqiba ubungakanani obufanelekileyo be-melamine foam kusetyenziso lwakho lwe-thermal okanye lwe-acoustic. Nokuba ufuna ukuyisebenzisela ulawulo lobushushu okanye njengegwebu le-acoustic, imathiriyeli yenziwe ngokwezifiso kakhulu ukuhlangabezana neemfuno zakho zokugquma.
6. I-semi-rigid, kodwa ibuye ibe bhetyebhetye
Okumangalisayo kukuba, igwebu le-melamine libhetyebhetye ngaphandle kobume bayo obuqinileyo. Oku kungenxa yokuba ukwakheka kwayo kweemolekyuli kunye nokwakheka kwayo kubonelela ukuguquguquka okuthile kwaye kuyivumela ukuba igqwese phantsi koxinzelelo okanye ukugoba ngaphandle kokuphulukana ngokusisigxina ukumila kwayo. Oku kuguquguquka kuvumela i-melamine foam ukuba iqhelane neendawo ezingaqhelekanga kwaye ihlangabezane noluhlu olubanzi lweemfuno ze-thermal kunye ne-acoustic insulation, ngelixa igcina ingqibelelo kunye nokusebenza kakuhle.
Ukusetyenziswa kwe-melamine foam:
I-Melamine foam ifaneleka kakhulu kwi-acoustic kunye ne-thermal insulation applications. Ineempawu ezibalaseleyo ze-acoustic, umlilo- kunye ne-flame-retardant. Ukongeza, ilula, iyaguquguquka kwaye ihlala ixesha elide.
Sigxila kwizicelo zayo ezimbini eziphambili:
Ukufakwa insulin
Ukuguquguquka kobushushu kuyingozi yokhuseleko kwaye kunokubangela umonakalo ongenakuguqulwa ngenxa yobushushu obugqithisileyo. Ukufakwa kwe-foam ye-Melamine kunomxholo ophezulu we-nitrogen, onceda ukulawula ukuhanjiswa kobushushu ngokuqhuba kunye nemitha, ngaloo ndlela ukwandisa ukhuseleko. I-conductivity yayo ephantsi ye-thermal icothisa ukwanda kwedangatye kunye nokudluliselwa kobushushu ngaphandle kwesidingo sezinye ii-retardants ezongezelelweyo zomlilo.
Amashishini amaninzi, afana ne-aerospace, izithuthi zikawonkewonke kunye nezonxibelelwano, ziyisebenzisela ukuphucula ukhuseleko kwizicelo ezifuna ukumelana nobushushu obuphezulu kunye nomlilo ophantsi kunye nokusasazeka komsi. Ngokomzekelo, i-foam ye-melamine ingasetyenziselwa ukufaka i-insulate: amacandelo elori kunye neenjini, i-ducts kwiinkqubo ze-HVAC, iindonga zeenqwelomoya kunye ne-fuselages, kunye nokunye.
Ukufunxa isandi
I-Melamine foam iphawuleka ngeempawu zayo zokufunxa isandi. Inobume beselula obuncinci obuthatha amaza omsindo, ihlukanise ukungcangcazela kwaye ithintele ingxolo ukuba ibuyele kwimigangatho, iindonga kunye neesilingi. Le propathi yenza i-melamine foam ibe sisithinteli esifanelekileyo kwimizi-mveliso, uthutho, i-aerospace, ulwakhiwo kunye nezinye izicelo.
Umzekelo, i-melamine foam ingasetyenziselwa ukuthomalalisa isandi esiveliswa ngabalandeli kunye nemibhobho kwiinkqubo zeHVAC. Isenokusetyenziswa ukugquma amagumbi enjini, iingcango, iindonga, kunye namagumbi omqhubi kunye nabakhweli koololiwe.
isishwankathelo
I-Melamine foam ngokungathandabuzekiyo sisisombululo esihle kakhulu sokufakwa kwe-thermal kunye ne-acoustic insulation. Ikhaphukhaphu, iyanqanda amadangatye, ayinamanzi kwaye ineempawu ezibalaseleyo ze-acoustic. Iyakwazi ukumelana namaqondo obushushu aphezulu kwaye ilawule ingxolo kunye nokungcangcazela ukwenzela indawo epholileyo nezolileyo. Isetyenziswa kuluhlu olubanzi lwamashishini kwiimfuno eziphezulu zokugquma ukusebenza.
