Puf panel inoshandiswa zvakanyanya mukuvaka, kuchengetera zvinhu zvinotonhorera, zvivakwa zvemaindasitiri, uye zvivakwa zve modular, nekuda kwekushanda kwazvo kwekudzivirira kupisa uye kumhanya kwekuisa. Kunyange hazvo vagadziri vezvivakwa nevavaki vachikoshesa mashandiro avo, mitengo inosiyana zvakanyanya zvichienderana nezvinhu zvakawanda zvinogona kuverengerwa.
Ukobvu hwePanel uye Kushanda kweInsulation
Ukobvu hwepakati pepaneru yesandwich yePU hunoenderana zvakananga nemutengo wayo. Ukobvu hwakajairika hunotangira pa40 mm kusvika 250 mm, nemapaneru akakora anopa insulation iri nani yekupisa (U-value yakaderera) asi achida zvinhu zvakawanda.
Panel yePuf ye100 mm inowanzodhura 20–30% kupfuura 50 mm yakaenzana nekuda kwekuwedzera kwehuwandu hwepolyurethane furo uye R-value yakawedzera, izvo zvinogona kuderedza zvakanyanya mutoro wekupisa nekutonhodza mukati mehupenyu hwechivako.
Kushanda zvakanaka kwekupisa kunokanganisa mutengo nekuti kuwana mafambiro ekupisa akaderera (anenge 0.022 W/m·K yePU) kunoda kuumbwa kwefuro kwakanyatsojeka uye kudzorwa kwemhando.
Zvinhu Zvikuru uye Kuwanda
Polyurethane pachayo inonyanya kudhura. Maumbirwo emasero akavharwa ePU foam akaomarara anopa insulation yakanaka zvichienzaniswa nezvimwe zvinoshandiswa zvakaita seEPS (expanded polystyrene), asi zvinhu zvayo zvekugadzira—polyols neisocyanates—zvinogadzirwa nepetrochemical zvine mitengo isingachinji. Ruzivo rweindasitiri runoratidza kuti mitengo yezvinhu zvekugadzira inoumba 60–70% yemari yese inoshandiswa pakugadzira mapaneru.
Pamusoro pezvo, kuwanda kwefuro kunokanganisa mashandiro uye mutengo. PU ine huwandu hwakanyanya inopa simba remakanika riri nani uye kuderedza kukwegura kwekupisa asi inowedzera mutengo nekuda kwekushandiswa kwakanyanya kwezvinhu uye kuoma kwekugadzirisa. Puf panel ine huwandu hwakanyanya hwepakati inogona kudhura ne15–25% kupfuura shanduro dzine huwandu hwakanyanya.
Zvinhu Zvine Runako
Mapaneru esandwich ane PU core yakasungirirwa pakati pemafafitera maviri esimbi. Aya anogona kunge ari simbi yakarungwa, simbi yakapendwa kare, kana aruminiyamu. Vamwe vagadziri vanotungamira, seHarbin Dongan Building Sheets Company, vanopa mapaneru epuf ane mapaneru eAl-Mg-Mn, izvo zvinogona kuita kuti paneru yesandwich ive yakareruka, inodzivirira ngura zvakanyanya, uye yakasimba.
Simbi yesimbi yakarukwa ndiyo inonyanya kudhura uye inopa simba rekudzivirira ngura zvakakwana, nepo simbi yakapendwa kare ine PVDF kana polyester coatings inowedzera kusimba uye runako. Ehe, zvichawedzera mutengo wekugadzira. Magadzirirwo esimbi yealuminium akareruka uye haapindi ngura asi achadhura zvakanyanya kupfuura simbi.
Ukobvu hweganda resimbi hunokoshawo. Kazhinji, ukobvu hweganda resimbi hunobva pa 0.4-0.6 mm. Dongan Company inogona kupa mapaneru ane ukobvu hweganda resimbi hwe 0.8mm. Gobvu reganda rinovandudza kuomarara kwepaneru uye kushanda zvakanaka kwekutakura mutoro, zvinorevawo mutengo wakakwira.
Kuongororwa kweMoto uye Maitiro eKuchengetedza
Panera reStandard Puf rinowanzo kwanisa kuwana mwero wekupisa moto wakaita seEuro class E. Zvisinei, mapurojekiti, sezvivakwa zveveruzhinji, zvikoro, zvipatara, anoda mazinga ekuchengetedza akakwira. Panera dzinokwanisa kupisa moto zvakanyanya dzinoda mafomura anodzivirira moto chaiwo kana mamwe macores, akadai sePIR, zvichiwedzera kuoma kwekugadzira uye mutengo.
Midziyo yekugadzira Sandwich Panels
Midziyo yekugadzira ine simba guru pamhando yema sandwich panels. Mutsetse wekugadzira wepamusoro uye wakabatana unogona kuve nechokwadi chekuti furo rakafanana re polyurethane core material pamwe nekusanganiswa kweplate yesimbi ye core material.
Kugadzirisa uye Zvinhu Zvakakosha
Mapaneru ePU akajairwa anodhura zvishoma nekuda kwekugadzirwa otomatiki. Saizi dzakagadzirwa, maumbirwo akasiyana, maprofayiro emupendero chaiwo, kana machira epamusoro eUV, anti-condensation, kana magadzirirwo ezvivakwa zvinowedzera mutengo.
Semuenzaniso, pamusoro pezvakajairikamapaneru esandwich, Dongan Company inogonawo kupa mapaneru esandwich ekushongedza. Vatengi vanogona kusarudza, kana kutogadzirisa, patani yeganda resimbi zvichienderana nezvavanoda uye maitiro echivako. Kugadzirwa kwemapatani akagadzirwa zvinoreva kuti mold yesimbi yakasiyana inofanira kugadzirwa, uye mutengo wemold ucharatidzwawo mumutengo wechigadzirwa chapera.
