Zithini iiSandwich Panels?
Iipaneli zesandwich zizinto ezidityanisiweyo ezenziwe ngaphambili eziqulathe iileya ezintathu eziphambili:
Izinto ezingundoqo – Ngokwesiqhelo, izinto ezikhaphukhaphu zokukhusela ezifana ne-polyurethane foam, i-polyisocyanurate (PIR) foam, okanye uboya beminerali.
Iileya ezimbini zangaphandle – Ngokwesiqhelo zenziwe ngentsimbi, i-aluminium, okanye ezinye izinto ezibonelela ngokuqina kunye nokuqina kwesakhiwo.
Uyilo lwesandwich lubonelela ngomthamo obalaseleyo wokuthwala umthwalo kunye nobunzima obuncinci, okwenza ukuba lube lukhetho olunomtsalane kwiindawo apho kufuneka khona ubushushu kunye nokuqina kwesakhiwo, njengaseluphahleni, eludongeni, nakwiindawo zokuhombisa.
Iintlobo zeeSandwich Panels
Iiphaneli zeSandwich zePolyurethane Foam – Baziwa ngeempawu zabo ezintle zokukhusela ubushushu kunye nokusebenza kakuhle kwamandla.
Iiphaneli zeSandwich zePolyisocyanurate (PIR) Foam – Ifana neepaneli ze-polyurethane foam kodwa zinokumelana nomlilo okwandisiweyo.
Iiphaneli zeSandwich zeWool yeMineral – Ilungele ukusetyenziswa kokumelana nomlilo okuphezulu kunye nokuthintela isandi, isetyenziswa rhoqo kwiindawo zoshishino.
Indima yePolyurethane kwiiphaneli zeSandwich
I-polyurethane foam yenye yezona zinto ziphambili ezisetyenziswa kakhulu kwiipaneli zesandwich ngenxa yeempawu zayo zokukhusela eziphezulu, ubume bayo obulula, kunye nokusebenza kakuhle kweendleko. I-polyurethane foam inika ukumelana okuphezulu kobushushu, inceda ukugcina amaqondo obushushu angaphakathi kunye nokunciphisa ukusetyenziswa kwamandla kwizakhiwo. Ikwakongeza amandla kunye nokuqina kwipaneli ngaphandle kokunyusa ubunzima bayo kakhulu.
Iingenelo eziphambili zePolyurethane Core kwiiSandwich Panels:
Ubushushu obugqwesileyo – Inceda ukugcina amaqondo obushushu ehlala ehleli kwaye inciphise iindleko zamandla.
Ilula – Kulula ukuyiphatha, ukuyithutha, nokuyifaka.
Ukuqina – Inika ukusebenza okuhlala ixesha elide kunye nokumelana okuphezulu nokufuma, iikhemikhali, kunye nokuguguleka komzimba.
Ixabiso eliphantsi – Inika ulungelelwaniso phakathi kokusebenza kunye nokufikeleleka.
Ukubaluleka kweePolyurethane Catalysts kwiMveliso yeeSandwich Panel
Ukuveliswa kweepaneli zesandwich ezisekelwe kwi-polyurethane kuxhomekeke kakhulu ekusetyenzisweni kwee-catalysts ze-polyurethane. Ezi catalysts ziqhuba ii-chemical reactions phakathi kwee-polyols kunye nee-isocyanates, eziziinxalenye ezimbini eziphambili ze-polyurethane foam. Ukukhethwa ngokuchanekileyo kwee-catalysts kuqinisekisa ukuba i-foam iphuhlisa iipropati ezifunekayo, ezinje ngoxinano, ubushushu, kunye namandla oomatshini, ngelixa ikwachaphazela ukusebenza kakuhle kwemveliso.
Iikhatalyst zePolyurethane zinokwahlulwa zibe ziindidi ezimbini eziphambili:
Ii-Amine Catalysts – Khuthaza ukusabela kwe-foam (ukuvuthela), okunceda ekudaleni ulwakhiwo lweseli lwe-foam.
Iikhatalisti zesinyithi – Khawulezisa ukusabela kwe-gelling, nto leyo enegalelo ekubeni i-foam ibe namandla kwaye iqine.
Imisebenzi ephambili yePolyurethane Catalysts:
Isantya soLawulo lokuphendula – IiCatalysts zilawula isantya apho i-polyurethane foam yakheka khona, ziqinisekisa umgangatho ohambelanayo kwaye zithintela iziphene ezifana nokushwabana okanye ukunamathelana kakubi.
Lungiselela iiPropati zeFoam – IiCatalysts zinefuthe kuxinano lwefoam, amandla, kunye nokuhanjiswa kobushushu, zinto ezo ezibalulekileyo ekusebenzeni kwepaneli yesandwich.
Phucula Imveliso – Iikhatalyst ezisebenzayo zinciphisa amaxesha okuvelisa ngokukhawulezisa inkqubo yokwenziwa kwefoam, nto leyo evumela abavelisi ukuba bavelise iipaneli zesandwich ngokukhawuleza nangendlela engabizi kakhulu.
