Mapanelo a Chipinda Chozizira cha PU Amathandizira Kusunga Zinthu Zozizira

Kusungira zinthu zozizira kumafuna kulondola komanso kugwira ntchito bwino, mapanelo a chipinda chozizira cha PU amagwira ntchito ngati muyezo wamakampani wotetezera kutentha. Mapanelo a sandwich a PU amapanga chotchinga, amathandiza zipinda zozizira kukhala ndi kutentha kokhazikika komanso kuchepetsa kutaya mphamvu. Omanga ambiri amasankha mapanelo a PU chifukwa amafuna kutetezera kutentha kwamphamvu, kuyika mwachangu, komanso kukhala ndi moyo wautali. Amasunga kutentha kokhazikika mkati kuti chakudya chikhale chotetezeka. Mabizinesi amadalira iwo kuti apereke zinthu zofunika komanso malo osungiramo zinthu.

Ubwino Wogwiritsa Ntchito Mapanelo a Chipinda Chozizira cha PU

Mapanelo a chipinda chozizira cha PU amapereka kutchinjiriza kwamphamvu chifukwa pakati pawo pamasonyeza kutchinjiriza kotsika kwambiri kwa kutentha. Pakati pa PU pamakhala kutchinjiriza kokhazikika pakati pa 38 ndi 42 kg pa mita imodzi ya kiyubiki. Kutchinjiriza kumeneku kumathandizira kutchinjiriza kotentha kwa 0.018 mpaka 0.024 W pa mita imodzi ya Kelvin. Panelo la chipinda chozizira cha PU la 100-mm limasunga kutentha kotsika pansi pa 0.25 W pa mita imodzi ya Kelvin. Zipinda zoziziritsira nthawi zambiri zimakhala ndi madigiri 18 kapena kuchepera, ndipo mapanelo a chipinda chozizira cha PU amakhala ndi kutentha kokhazikika m'mikhalidwe iyi. Ogwiritsa ntchito ambiri amanena kuti amasunga mphamvu ndi 10 mpaka 18 peresenti akasintha kuchoka pa thovu lotsika kwambiri kupita ku machitidwe a PU okwera kwambiri. Mapanelo a PU amasunganso kuyamwa kwa chinyezi pansi pa 2 peresenti ndi voliyumu, zomwe zimateteza kutchinjiriza kokhazikika kwa nthawi yayitali.

Mapanelo a PU amapereka mitundu yambiri ya zipinda zozizira, kuphatikizapo zipinda zoziziritsira, zipinda zoziziritsira, malo osungira zipatso, malo opangira nyama, ndi malo osungira mbewu. Panelo la PU la 75-mm limagwirizana ndi zipinda zomwe kutentha kwake kuli pakati pa madigiri 0 ndi 10. Panelo la 100 mm limagwirizana ndi madigiri 10 mpaka 18. Panelo la 150 mm limagwirizana ndi madigiri 20. Ndipo 200 mm limagwirizana ndi madigiri 25 kapena kuchepera.

Ma sandwich panel a PU amagwiritsa ntchito zikopa zachitsulo zomwe zimakhala ndi makulidwe kuyambira 0.4 mpaka 0.6 mm. Zikopazi zimakwaniritsa mphamvu ya 235 mpaka 280 MPa. Pamwamba pa chitsulo cholimba chimateteza pakati pa thovu ndipo chimathandizira katundu wamkati mwa zida. Panel ya PU ya 100 mm imafika pamphamvu yokakamiza ya 150 mpaka 180 kPa. Mphamvu iyi imatsimikizira kuti imagwirizana bwino muzipinda zozizirandi magalimoto ambiri oyenda pansi. Ambirimalo osungira oziziraOmanga amagwiritsa ntchito malo olumikizirana ndi lilime ndi groove chifukwa amathandiza kuti mpweya usalowe. Malo olumikizirana otsekedwa bwino amachepetsa kutuluka kwa mphamvu ndi 10 mpaka 15 peresenti. Ma panelo amawonetsanso kuchepetsa phokoso pafupifupi ma decibel 25 mpaka 28, zomwe zimathandiza kuwongolera phokoso mkati mwa malo ogwirira ntchito.

Ubwino Wapamwamba wa Zinthu

Zipangizo zopangira ndizomwe zimatsimikiza kutalika kwa chinthu chomaliza. Popeza gulu la sandwich lili ndi ma panel ambiri achitsulo, mankhwala oletsa dzimbiri pamwamba pa chinthucho ndi ofunikira kwambiri. Kuphimba kwa zinc kwa 120g/m² mpaka 275g/m² kumateteza chitsulocho. Izi zimaletsa dzimbiri m'malo ozizira ozizira. Zophimba zapamwamba monga PVDF kapena HDP zimapewa dzimbiri la mankhwala. Kukhuthala kwa utoto nthawi zambiri kumakhala ma microns 25. Choteteza ichi chimatsimikizira kuti mtunduwo sutha.

Kampani ya Harbin Dong`an Building Sheets Company ndi kampani yotsogola yopanga mapanelo a sandwich ku China. Kampaniyi ili ndi mbiri yakale kwambiri kwa zaka zoposa 40. Kampani ya Dong`an imayang'ana kwambiri ubwino wa zinthu zake. Dong`an imagwiritsa ntchito zitsulo kuchokera kwa ogulitsa apamwamba. Nthawi zambiri amagwiritsa ntchito zinthu zochokera ku makampani otchuka komanso apamwamba. Kukhuthala kwa pepala lachitsulo kumakhala kuyambira 0.4 mm mpaka 0.8 mm kuti atsimikizire kuti kapangidwe kake ka zinthu za mapanelo a sandwich ndi kolimba. Dong`an imayang'ana kwambiri gulu lililonse la zinthu zopangira. Zipangizo zomwe zimakwaniritsa miyezo yapadziko lonse lapansi ndi zomwe zimalowa mu mzere wopanga.

Ukadaulo Wopanga ku Harbin Dong`an

Harbin Dong`an amagwiritsa ntchito njira zamakono zopangira. Njira yawo yopangira yopitilira imapanga mtundu wofanana. Makina apakompyuta amawongolera njira yopangira thovu molondola. Izi zimatsimikizira kuchulukana kofanana pagawo lonse. Amagwiritsa ntchito makina opangira thovu amphamvu kwambiri. Kupanikizika kwa jakisoni kumafika pa mipiringidzo 150. Izi zimatsimikizira kuti thovu limadzaza ngodya iliyonse bwino. Mphamvu yolumikizirana pakati pa chitsulo ndi thovu ndi yapadera. Imaposa 0.09 MPa m'mayeso wamba. Nthawi yokwera thovu imakhala mkati mwa masekondi asanu ndi atatu mpaka khumi, zomwe zimathandiza kupanga maselo ofanana. Laminator imagwiritsa ntchito kupanikizika koyenera kwa 0.1 mpaka 0.2 MPa panthawi yokonza.

Kupanikizika kofanana kumeneku kumathetsa kupindika kwa mapanelo ndi kusakhazikika kwa pamwamba. Ukadaulo wapamwamba wodulira umatsimikizira kulondola kwa miyeso. Mapanelo amafika pamalopo okonzeka kusonkhana. Kulekerera kumakhalabe mkati mwa mamilimita awiri. Fakitale imagwiritsa ntchito zida zodzipangira zokha zomwe zimachepetsa kuwonongeka kwa makina ndikusunga kusintha kwa m'mphepete pansi pa 1 mm. Kulondola kumeneku kumachotsa mipata panthawi yoyika. Malo osalala achitsulo amalola kuyeretsa kosavuta ndikuthandizira kutsatira HACCP ndi GMP. Zinthu izi zimapangitsa mapanelo a PU kukhala abwino kwambiri pokonza chakudya, mankhwala, ndi ntchito zoyendera.

Harbin Dong`an imapereka zida zowonjezera monga zidutswa zamakona, njanji za aluminiyamu, zotsekera, ndi zomangira zosapanga dzimbiri. Zida zimenezi zimawonjezera moyo wa makinawo ndikuletsa dzimbiri m'malo ozizira. Mafilimu oteteza okhala ndi makulidwe a ma micron 60 mpaka 80 amachepetsa kuwonongeka kwa mayendedwe mpaka pansi pa 1 peresenti. Ogula amapeza chidaliro chifukwa gawo lililonse limatsatira njira zokhazikika pansi pa kayendetsedwe ka khalidwe la ISO 9001.

Utumiki ndi Kusintha

Harbin Dong`an amaika patsogolo kukhutitsidwa kwa makasitomala ndi chithandizo. Gulu lawo la mainjiniya limathandiza pakupanga chipinda chozizira. Amawerengera makulidwe ofunikira a panel kutengera malo. Dong`an imapereka mayankho okonzedwa bwino pa zosowa zilizonse. Mphamvu yawo yopangira imaposa 2,000 sikweya mita tsiku lililonse. Izi zimatsimikizira kutumiza mwachangu kumapulojekiti akuluakulu. Amapereka chitsimikizo cha nthawi yofika zaka 15. Kudzipereka kumeneku kumatsimikizira chidaliro chawo muubwino wa chinthu. Thandizo laukadaulo limakhalapobe nthawi yonse yokhazikitsa. Makasitomala amalandira malangizo okhudza kukonza ndi kusamalira.
