Ukugcinwa kweendawo ezibandayo kufuna ukuchaneka nokusebenza kakuhle, iiphaneli zegumbi elibandayo le-PU zisebenza njengomgangatho weshishini lokufakelwa kobushushu. Iiphaneli zesandwich ze-PU zenza umqobo, zinceda amagumbi abandayo ukuba agcine ubushushu obuzinzileyo kwaye zinciphise ukulahleka kwamandla. Abakhi abaninzi bakhetha iiphaneli ze-PU kuba bafuna ukufakelwa kobushushu okuqinileyo, ukufakelwa ngokukhawuleza, kunye nobomi obude benkonzo. Zigcina ubushushu obuzinzileyo bangaphakathi ukuze kukhuseleke ukutya. Amashishini axhomekeke kuzo kwiimpahla kunye neendawo zokugcina impahla.
Iingenelo zokusetyenziswa kweePaneli zeGumbi elibandayo lePU
Iiphaneli zegumbi elibandayo le-PU zibonelela ngobushushu obuqinileyo kuba ubunzulu bubonisa ubushushu obuphantsi kakhulu. Ubunzulu be-PU obuqhelekileyo bufikelela kubuninzi obuphakathi kwama-38 nama-42 kg nge-cubic meter nganye. Olu bunzima buxhasa amaxabiso obushushu obuphakathi kwama-0.018 ukuya kuma-0.024 W nge-Kelvin ngemitha nganye. Iphaneli yegumbi elibandayo le-PU eyi-100-mm igcina ubushushu bungaphantsi kwama-0.25 W nge-square meter nganye yeKelvin. Amagumbi abandayo adla ngokusebenza kumaqondo obushushu angaphantsi kwama-18 degrees okanye ngaphantsi, kwaye iiphaneli zegumbi elibandayo le-PU zigcina ubushushu obuzinzileyo kwezi meko. Abasebenzisi abaninzi baxela ukonga kwamandla ukusuka kwi-10 ukuya kwi-18 ekhulwini xa bephucula ukusuka kwi-foam enobunzima obuphantsi ukuya kwiinkqubo ze-PU ezinobunzima obuphezulu. Ii-PU cores zikwagcina ukufunxwa komswakama kungaphantsi kwama-2 ekhulwini ngobuninzi, okukhusela ixabiso lobushushu bexesha elide.
Iiphaneli ze-PU zibonelela ngeentlobo ezininzi zamagumbi abandayo, kuquka amagumbi efriji, amagumbi okupholisa, indawo yokugcina iziqhamo, iindawo zokucubungula inyama, kunye neendawo zokugcina imbewu. Iphaneli ye-PU engama-75-mm ifanele amagumbi anamaqondo obushushu aphakathi kwama-0 nama-10 degrees. Iphaneli eyi-100 mm ifanele ama-10 ukuya kuma-18 degrees ukusuka kwi-10 ukuya kwi-18 degrees ukusuka kwi-150 mm. Iphaneli eyi-200 mm ifanele ama-25 degrees ukusuka kwi-20 degrees ukusuka kwi-200 mm. Kwaye i-200 mm ifanele ama-25 degrees nangaphezulu ukusuka kwi-200 degrees ukusuka kwi-100 mm ukuya kwi-200 degrees ukusuka kwi-200 degrees nangaphezulu.
Iiphaneli zesandwich ze-PU zisebenzisa izikhumba zentsimbi eziqala kwi-0.4 ukuya kwi-0.6 mm ubukhulu. Ezi zikhumba zifikelela kumandla okuvelisa angama-235 ukuya kwi-280 MPa. Umphezulu wentsimbi oqinileyo ukhusela umongo wefoam kwaye uxhasa imithwalo yezixhobo zangaphakathi. Iphaneli ye-PU eqhelekileyo eyi-100-mm ifikelela kumandla oxinzelelo angama-150 ukuya kwi-180 kPa. La mandla aqinisekisa ukulungelelaniswa okuzinzileyo kwiamagumbi abandayongezithuthi ezininzi. Uninziindawo yokugcina ebandayoAbakhi basebenzisa amalungu olwimi kunye nomngxuma kuba aphucula ukungabi namoya. Amalungu onxibelelwano avaliwe kakuhle anciphisa ukuvuza kwamandla nge-10 ukuya kwi-15 ekhulwini. Iiphaneli zikwabonisa amaxabiso okunciphisa isandi kufutshane ne-25 ukuya kwi-28 decibels, nto leyo enceda ukulawula ingxolo ngaphakathi kwiindawo zokucubungula.
Umgangatho wezinto ezisemgangathweni ophezulu
Izinto eziluhlaza zimisela ixesha elide lemveliso yokugqibela. Ekubeni iphaneli yesandwich ineephaneli ezininzi zesinyithi, unyango lokulwa nomhlwa kumphezulu wemveliso lubaluleke ngakumbi. Ugqubuthelo lwezinc oluyi-120g/m² ukuya kwi-275g/m² lukhusela isinyithi. Oku kuthintela umhlwa kwiindawo ezibandayo ezifumileyo. Ugqubuthelo oluphezulu olufana ne-PVDF okanye i-HDP luyamelana nokugqwala kweekhemikhali. Ubukhulu bepeyinti buhlala bulingana ne-25 microns. Olu gqubuthelo luqinisekisa ukuba umbala awupheli.
Inkampani iHarbin Dong`an Building Sheets yinkampani ephambili yokuvelisa iipaneli zesandwich eTshayina. Le nkampani inembali engaphezulu kweminyaka engama-40. Inkampani iDong`an ixabisa kakhulu umgangatho weemveliso zayo. IDong`an ifumana intsimbi kubaboneleli abaphambili. Bahlala besebenzisa izinto ezivela kwiimpawu ezidumileyo nezikumgangatho ophezulu. Ubukhulu bephepha lesinyithi buqala kwi-0.4 mm ukuya kwi-0.8 mm ukuqinisekisa ukuba ulwakhiwo lwemveliso yeepaneli zesandwich luqinile. IDong`an ihlola yonke ibhetshi yezinto eziluhlaza ngokungqongqo. Zizinto ezihlangabezana nemigangatho yamazwe ngamazwe kuphela ezingena kumgca wemveliso.
Itekhnoloji yokuvelisa eHarbin Dong`an
IHarbin Dong`an isebenzisa imigca yokuvelisa yanamhlanje. Umgca wabo wemveliso oqhubekayo udala umgangatho ohambelanayo. Iinkqubo zekhompyutha zilawula inkqubo yokufutha ngokuchanekileyo. Oku kuqinisekisa uxinano olufanayo kuyo yonke iphaneli. Basebenzisa oomatshini bokufutha abanoxinzelelo oluphezulu. Uxinzelelo lwe-injection lufikelela kwi-150 bar. Oku kuqinisekisa ukuba i-foam izalisa yonke ikona ngokugqibeleleyo. Amandla okubopha phakathi kwentsimbi kunye ne-foam ayamangalisa. Idlula i-0.09 MPa kwiimvavanyo eziqhelekileyo. Ixesha lokunyuka kwe-foam lihlala kwimizuzwana esibhozo ukuya kwelishumi, exhasa ukwakheka kweeseli ezifanayo. I-laminator isebenzisa uxinzelelo olulinganisiweyo lwe-0.1 ukuya kwi-0.2 MPa ngexesha lesigaba sokuphiliswa.
Olu xinzelelo olufanayo lususa ukugoba kwephaneli kunye nokungahambi kakuhle komphezulu. Itekhnoloji yokusika ephucukileyo iqinisekisa ukuchaneka kobukhulu. Iiphaneli zifika kwindawo zilungele ukuhlanganiswa. Ukunyamezela kuhlala kungaphakathi kweemilimitha ezi-2. Umzi-mveliso usebenzisa izixhobo zokubeka izinto ezizenzekelayo ezinciphisa umonakalo woomatshini kwaye zigcina ukuguquguquka komphetho kungaphantsi kwe-1 mm. Oku kuchaneka kususa izikhewu ngexesha lokufakwa. Iindawo zentsimbi ezithambileyo zivumela ukucocwa okulula kwaye zixhasa ukuhambelana kwe-HACCP kunye ne-GMP. Ezi mpawu zenza iiphaneli ze-PU zilungele ukucubungula ukutya, amayeza, kunye nokusetyenziswa kwezinto.
