Mawu Oyamba
Cold chain logistics yakhala njira yofunika kwambiri yothandizira kutentha kwapadziko lonse-katundu wosamva kutentha, kuphatikiza chakudya chowuma, zokolola zatsopano, mankhwala, ndi zinthu zachilengedwe. Pamene maukonde ogawa akukhala ovuta komanso mtunda wobweretsera ukuwonjezeka, zofunikira zaukadaulo pazida zoyendera mufiriji zakhala zovuta kwambiri.
Munkhaniyi, zida zotsekera zomwe zimagwiritsidwa ntchito pomanga thupi lagalimoto zimagwira ntchito yofunika kwambiri pakuwunika mphamvu zamagetsi, kukhazikika kwa kutentha, komanso magwiridwe antchito onse. Mwa njira zosiyanasiyana zotsekera, ma XPS Refrigerated Truck Body Panel alandiridwa kwambiri chifukwa chogwira ntchito moyenera pakutchinjiriza kwamafuta, mphamvu zamapangidwe, komanso kukana chinyezi.
Mosiyana ndi{0}}zida zodzitchinjiriza zanthawi zonse, masangweji a XPS amaphatikiza masanjidwe angapo opangidwa ndi makina ogwirizana. Kuchita kwawo sikumatanthauzidwa kokha ndi kusankha kwazinthu komanso ndi ukadaulo wodziwika bwino monga matenthedwe amafuta, mphamvu yopondereza, kachulukidwe, kulolerana kwa makulidwe, komanso kukhulupirika kolumikizana.
Nkhaniyi ikupereka mwatsatanetsatane zaukadaulo wa XPS Refrigerated Truck Body Panels, ndikuwunikira kwambiri zomwe zimatanthauzira-mapulogalamu enieni apadziko lonse lapansi.
1. Mapangidwe Azinthu ndi Mafotokozedwe Apangidwe
1.1 XPS Foam Core Material Properties
Pakati pa XPS Refrigerated Truck Body Panels ndi extruded polystyrene foam (XPS), chinthu cholimba chotchinjiriza chomwe chimapangitsa kuti cell ikhale yotsekeka-.
Density Specification
Kuchulukana kwa thovu la XPS nthawi zambiri kumakhala pakati pa 28-45 kg/m³ kutengera zomwe mukufuna kugwiritsa ntchito. Kachulukidwe kachulukidwe nthawi zambiri kumapangitsa kuti mphamvu zopondereza komanso kukhazikika kwapangidwe zikhazikike, pomwe kachulukidwe kakang'ono kumapangitsa kuti mtengo wake ukhale wabwino komanso umachepetsa kulemera.
Otsekedwa{{0}Kapangidwe ka Maselo
Chimodzi mwazinthu zofunika kwambiri za XPS ndi mawonekedwe ake otsekedwa-maselo. Kupitilira 90% ya voliyumu yamkati imapangidwa ndi ma cell osindikizidwa, omwe amachepetsa kwambiri kutentha komanso kuyamwa kwa chinyezi.
Kukhazikika kwazinthu
Foam ya XPS imasunga zinthu zokhazikika pakapita nthawi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito kwa nthawi yayitali-mu XPS Refrigerated Truck Body Panels popanda kuwonongeka kwakukulu pakugwira ntchito kwa zotsekemera.
1.2 Zofotokozera Zachikopa Zapamwamba
Zikopa zakunja ndi zamkati za mapanelo a XPS zimagwira ntchito yofunika kwambiri pakulimbitsa kamangidwe komanso kuteteza chilengedwe.
FRP (Fiberglass Reinforced Plastic)
FRP imagwiritsidwa ntchito kwambiri chifukwa cha kukana kwa dzimbiri, katundu wopepuka, komanso kumaliza kwake kosalala. Amagwiritsidwa ntchito kwambiri pazakudya-njira zoyendera mufiriji.
Mapepala a Aluminium
Aluminiyamu-mapanelo okhala ndi nkhope amapereka mphamvu zapamwamba komanso mawonekedwe amakampani. Amagwiritsidwa ntchito m'magalimoto amtundu wa firiji kapena magalimoto olemera-onyamula katundu.
Chitsulo chosapanga dzimbiri
Zitsulo zosapanga dzimbiri zimagwiritsidwa ntchito pazofunikira zomwe zimafunikira kulimba kwambiri komanso ukhondo, monga zoyendera zamankhwala kapena mayendedwe amankhwala.
Chilichonse chapamwamba chimakhudza magwiridwe antchito a XPS Refrigerated Truck Body Panels.

Thermal conductivity ndi chimodzi mwazizindikiro zofunika kwambiri pazida zotsekera.
Thermal conductivity ya XPS nthawi zambiri imachokera ku 0.028 mpaka 0.035 W/m·K, kutengera kachulukidwe ndi kupanga.
Kutsika kwa λ kumawonetsa magwiridwe antchito abwinoko. Mu XPS Refrigerated Truck Body Panels, izi zimatanthawuza mwachindunji kusamutsa kutentha pakati pa chilengedwe chakunja ndi chipinda cha firiji.
2.2 Kusunga Kutentha Kwambiri
Kusunga kutentha kumatanthawuza kuthekera kwa gulu kuti likhale lokhazikika mkati mwa nthawi.
Zinthu zazikulu zomwe zimalimbikitsa ndi izi:
Makulidwe a gulu
Kuchuluka kwa thovu
Kusindikiza kukhulupirika pakati pa mapanelo
Kuwoneka kwa zinthu zapamwamba
Thicker XPS Refrigerated Truck Body Panels nthawi zambiri amapereka kutentha kwabwinoko, makamaka patali-pamtunda kapena mozama-mayimidwe amagalimoto.
2.3 Mphamvu Yamphamvu Mwachangu
Chimodzi mwazinthu zofunika kwambiri-zopindulitsa zamapaneli a XPS ndikuchepetsa kugwiritsa ntchito mphamvu.
Pochepetsa kulowetsedwa kwa kutentha, zigawo za firiji zimagwira ntchito pafupipafupi komanso kuchepetsa katundu. Izi zimabweretsa:
Kuchepetsa kugwiritsa ntchito mafuta a dizilo{{0}magalimoto oyenda mufiriji
Kuchepetsa kuvala kwa kompresa mu kachitidwe ka firiji
Kuchita bwino-kwanthawi yayitali
Muzochita zazikulu-zoyendetsa bwino, zopindulazi zimatha kuchepetsa kwambiri ndalama zonse zoyendetsera ntchito.
3. Mphamvu zamakina ndi Zolemba Zopangira Mapangidwe
3.1 Mphamvu Yopondereza
Mphamvu zoponderezedwa ndi chizindikiro chachikulu cha -kunyamula katundu.
XPS thovu lomwe limagwiritsidwa ntchito mu XPS Refrigerated Truck Body Panels nthawi zambiri limapereka mphamvu zopondereza kuyambira 200 mpaka 500 kPa, kutengera kuchuluka kwa kachulukidwe.
Izi zimapangitsa kuti mapanelo azitha kupirira:
Cargo stacking pressure
Kuyika pansi m'magalimoto afiriji
Kupanikizika kwamapangidwe panthawi yoyendetsa
Mphamvu zopondereza zapamwamba ndizofunikira kwambiri pamapanelo apansi.
3.2 Flexural Mphamvu ndi Kukaniza Kwamphamvu
Flexural mphamvu imayesa kuthekera kwa gululo kukana mphamvu zopindika.
Muzochitika zenizeni-padziko lonse lapansi, mapanelo amagalimoto osungidwa mufiriji amakumana ndi kugwedezeka kwa misewu, kuthamanga kwadzidzidzi, komanso kukhathamiritsa.
Kapangidwe ka masangweji a XPS Refrigerated Truck Body Panels amalola zikopa zakunja kutengera kupsinjika komanso kupsinjika, pomwe XPS pachimake imagawa mphamvu zamkati mofanana.
Izi zimachepetsa kwambiri chiwopsezo pakagwiritsidwe ntchito kwanthawi yayitali-.
3.3 Kukhazikika Kwamapangidwe ndi Kugawa Katundu
Kukhazikika kwamapangidwe kumatheka pogwiritsa ntchito kuphatikiza:
Mkulu-kachulukidwe ka thovu ka XPS
Zikopa zakunja zolimbitsa
Zomatira zomangira zigawo
Kukonzekera uku kumapangitsa mphamvu zonyamula katundu kuti zigawidwe pagawo lonse lapansi m'malo mokhazikika pamalo amodzi.
Zotsatira zake, XPS Refrigerated Truck Body Panels imasunga umphumphu ngakhale pansi pamayendedwe amphamvu.
3.4 Dimensional Kukhazikika
Kukhazikika kwa dimensional kumatanthauza kuthekera kwa gululo kukhalabe ndi mawonekedwe pansi pakusintha kwa kutentha.
Zinthu za XPS zimasonyeza kukhazikika kwa kutentha kwakukulu, kuyambira -50 digiri kufika pa +75 digirii .
Izi zimawonetsetsa kuti XPS Refrigerated Truck Body Panel sizimapindika, kuchepera, kapena kukulirakulira panthawi yogwira ntchito.
4. Kukaniza kwa Chinyezi ndi Zolemba Zogwira Ntchito Zachilengedwe
4.1 Mlingo wa Mayamwidwe a Madzi
Ubwino umodzi wofunikira wa zinthu za XPS ndi kuchuluka kwake kwamadzi otsika kwambiri, omwe amakhala pansi pa 1%.
Izi zimalepheretsa:
Kuwonongeka kwa insulation
Kufooka kwamapangidwe
Kukula kwa bakiteriya kapena nkhungu
M'malo okhala mufiriji momwe ma condensation ndi ofala, izi ndizofunikira kuti-zigwire ntchito kwanthawi yayitali.
4.2 Kuchita Bwino kwa Vapor Barriers
Maselo otsekedwa-wa XPS amagwira ntchito ngati chotchinga mpweya wachilengedwe.
Izi zimalepheretsa kusuntha kwa chinyezi kulowa pachimake, kuwonetsetsa kuti XPS Refrigerated Truck Body Panels imasunga magwiridwe antchito nthawi zonse.
Zimachepetsanso kuyanika kwamkati, komwe kuli kofunikira paukhondo-mafakitale omwe amakhudzidwa kwambiri ndi chakudya ndi mankhwala.
4.3 Kukaniza chilengedwe
Mapanelo a XPS adapangidwa kuti azigwira ntchito zosiyanasiyana zachilengedwe, kuphatikiza:
Madera a chinyezi chachikulu
Malo amchere amchere-akunyanja
Kusiyanasiyana kwa kutentha kwakukulu
Kuwonekera kwa mankhwala kuchokera kwa oyeretsa
Izi zimawapangitsa kukhala oyenera ntchito zapadziko lonse lapansi zozizira.
5. Kupanga, Dimensional, ndi Processing Specifications
5.1 Miyezo ya Makulidwe a Panel
