Mapanelo osungiramo zinthu zozizira amagwira ntchito ngati zigawo zazikulu za kayendedwe ka zinthu zozizira ndipo amakhudza mwachindunji ubwino wa malo osungiramo chakudya ndi mankhwala. Katundu wowonongeka amafunika kuwongolera kutentha kokhazikika nthawi yonse yosungiramo ndi mayendedwe. Panelo yoyenerera yosungiramo zinthu zozizira iyenera kupirira kuzizira kwambiri pa -30 °C popanda kutaya ntchito. Panelo iyeneranso kukhala yokhazikika m'malo ozizira kwa nthawi yayitali yogwira ntchito.
Kumvetsetsa njira zopangira kumathandiza ogula kusankha zinthu zoyenera komanso ogulitsa odalirika. Chidziwitsochi chimachepetsanso zoopsa za polojekiti komanso ndalama zogwirira ntchito kwa nthawi yayitali. Opanga amapanga mapanelo osungiramo zinthu zozizira kudzera munjira zingapo zofunika.
Masitepe awa akuphatikizapo kupanga ma panel achitsulo, kupopera zomatira, ndi kulowetsa thovu. Njirayi imapitilira ndi thovu la zinthu zapakati, kudula ma panel, kuyeretsa, ndi kuwunika komaliza. Gawo lililonse limakhudza mphamvu ya ma panel, kugwiritsa ntchito bwino kwa zotetezera kutentha, komanso nthawi yogwira ntchito. Opanga ayenera kuwongolera gawo lililonse kuti atsimikizire kuti zinthuzo ndi zabwino nthawi zonse.
Kusankha Zinthu Zopangira Mapanelo Osungira Zinthu Zozizira
Ubwino wa mapanelo achitsulo uyenera kuganiziridwa kwambiri. Mapanelo achitsulo amagwira ntchito ngati chigoba cha mapanelo osungiramo zinthu ozizira. Amatsimikiza mwachindunji mphamvu yonse ndi kukhazikika kwa magawo. Chosankha chachikulu chimagwiritsa ntchito mapanelo achitsulo amtundu wapamwamba okhala ndi makulidwe a 0.5 mm. Opanga amapaka mapanelo awa ndi utomoni wa polyester kuti asawonongeke ndi dzimbiri. Chophimbacho chimatetezanso mapanelo kuti asawonongeke ndi kuwonongeka panthawi yonyamula ndi kukhazikitsa.
Ogulitsa ena ang'onoang'ono amachepetsa mitengo mwa kuchepetsa ndalama zogulira zinthu. Nthawi zambiri amagwiritsa ntchito mapanelo achitsulo okhala ndi makulidwe ozungulira 0.3 mm. Mapanelo otere amawonongeka mosavuta akamanyamula katundu kapena kusintha kwa kutentha. Kusintha kwa kapangidwe kake kumawonjezera kuchuluka kwa ndalama zokonzera ndi kukonza. Mitengo yotsika yoyambirira nthawi zambiri imabweretsa ndalama zambiri zogulira nthawi yayitali.
Ogulitsa abwino amagwiritsa ntchito miyezo yokhwima ya zinthu. Monga momwe Harbin Dongan Building Sheets imagwiritsira ntchito mapanelo achitsulo pakati pa 0.4 ndi 0.8 mm makulidwe. Kulemera kwa zinc coverage kumafika osachepera 120 g/m² mbali zonse ziwiri. Izi zimaletsa dzimbiri kwa zaka zoposa khumi. Mapanelo okhuthala amathandizanso kukana kukhudzidwa ndi kuuma kwa kapangidwe kake. Ubwino uwu umathandizira ntchito zosungiramo zinthu zozizira kwa nthawi yayitali.
Ubwino wa zinthu zapakati umagwiranso ntchito yofunika kwambiri. Pakati pake pamatsimikizira momwe kutentha kumagwirira ntchito komanso momwe mphamvu zimagwiritsidwira ntchito bwino. Thovu la polyurethane lopanikizika kwambiri limakhala lofunika kwambiri pamsika wamakono wosungiramo zinthu zozizira. Kutentha kwake kumakhalabe pa 0.024 W/(m·K) kapena pansi pake. Kutentha kochepa kumachepetsa kusamutsa kutentha ndi kutayika kwa mphamvu.
Opanga zinthu zabwino amawongolera mosamala kuchuluka kwa thovu. Dongan imasunga kuchuluka kwa polyurethane pakati pa 38 ndi 42 kg/m³. Mtundu uwu umagwirizanitsa bwino kutenthetsa ndi mphamvu ya makina. Kuchuluka kochepa kumafooketsa kapangidwe kake, pomwe kuchuluka kwakukulu kumachepetsa kutenthetsa. Kuwongolera bwino kuchuluka kumatsimikizira kuti ntchitoyo ndi yokhazikika pamene katunduyo akulemera.
Zinthu zothira thovu zimakhudzanso ubwino wa zinthu zothira thovu. Opanga ayenera kusankha zinthu zothira thovu zapamwamba monga HCFC-141B. Zinthu zothira thovu zapamwamba zimapanga maselo ofanana a thovu komanso maselo otsekedwa kwambiri. Zinthu zothira thovu zofanana zimathandiza kuti kutentha kusamatenthe komanso kukana chinyezi. Izi zimathandiza kuti zinthu zothira thovu zisamatenthe kwa nthawi yayitali.
Njira Yopangira Ma Cold Storage Panels
Mizere yopangira yokha imalola kuwongolera bwino njira. Kupanga kwamakono kumafuna kuchuluka kwa zinthu kolondola kwambiri. Mizere yokhazikika yokha imakwaniritsa zofunikira izi bwino. Msika ukukonda kwambiri kupanga mapanelo osungira ozizira okha.
Makina a makompyuta amawongolera kutentha kwa thovu, kuthamanga, ndi nthawi yochitira zinthu. Makinawa amasunga zinthu zokhazikika nthawi yonse yopangira. Thovu la zinthu zopangira limasinthasintha pafupifupi 38 °C. Kutentha kokhazikika kumawongolera kapangidwe ka thovu ndi magwiridwe antchito ogwirizana. Kuchuluka kwa maselo otsekedwa kumafika osachepera 95 peresenti thovu likatuluka.
Kutulutsa thovu lopangidwa ndi manja kumapereka ubwino womveka bwino kuposa njira zogwirira ntchito pamanja. Kutulutsa thovu lopangidwa ndi manja mwachizolowezi kumapanga kuchulukana kosagwirizana komanso malo ofooka. Kutulutsa thovu lopangidwa ndi manja kokha kumapanga ma cores ofanana pa gulu lililonse. Kusintha kwa kutentha kumakhalabe pansi pa 0.002 W/(m·K). Kuteteza kokhazikika kumathandizira kuti chipinda chozizira chigwire bwino ntchito.
Mapanelo abwino kwambiri amachepetsa kugwiritsa ntchito mphamvu pogwiritsa ntchito akakhazikitsa. Ogwiritsa ntchito nthawi zambiri amasunga ndalama zokwana 15 mpaka 20 peresenti pamagetsi. Kuchepa kwa kufunikira kwa mphamvu kumathandizira kuti ntchito iyende bwino komanso kuti zinthu zisamayende bwino. Kuteteza kokhazikika kumatetezanso katundu wosungidwa bwino.
Ubwino wa mgwirizano umatsimikizira kuti umakhala nthawi yayitali. Kapangidwe ka gululi kamafuna kulimba kwambiri pakati pa zikopa zachitsulo ndi zinthu zapakati. Kulimba kwa mgwirizano kumakhudza mwachindunji kulimba ndi chitetezo. Kulephera kwambiri kosungira zinthu zozizira kumachitika chifukwa cha kugawanika kwa gululi. Zikopa zachitsulo zimapatukana pamene mphamvu yolumikizana siili yokwanira.
Opanga ayenera kuonetsetsa kuti ali ndi mphamvu zokwanira zolumikizira. Mphamvu zolumikizira ziyenera kupitirira 1.0 kg/cm². Bolodi iliyonse ya sikweya mita iyenera kupirira mphamvu yokoka ya tani imodzi. Miyezo iyi imaletsa kulekanitsidwa chifukwa cha kutentha.
Dongan amagwiritsa ntchito guluu wa polyurethane wapamwamba kwambiri wokhala ndi zigawo ziwiri. Guluu uwu umapereka mphamvu yolimba komanso yolimba yolumikizira. Mapanelo atsopano amachira pa 70 °C kwa maola 24. Kukonza guluu kumathandiza guluu kukhala ndi mphamvu zokwanira. Njirayi imaletsa kusweka kwa denga pakasintha kwambiri kutentha.
Kuwunika Kokhwima Kwabwino
Kuwunika bwino khalidwe kumathandiza kuti zinthu zizigwira ntchito bwino. Kuwunika mawonekedwe ake ndi gawo loyamba lowongolera khalidwe. Dongan imagwiritsa ntchito miyezo yowunikira bwino mawonekedwe. Malo ozungulira ayenera kukhala opanda zolakwika zooneka.
Kusafanana kwa pamwamba kuyenera kukhala pansi pa 1.5 mm. Kuzama kwa kukanda sikuyenera kupitirira 0.2 mm. Kupotoka kwa diagonal kuyenera kukhala pansi pa 2 mm. Miyezo iyi imatsimikizira kukhazikitsidwa kolondola ndi kulumikizana kwa mapanelo kolimba. Mawonekedwe abwino akuwonetsanso khalidwe la mkati mwa kapangidwe.
Kuwunika mosamala kumaonetsetsa kuti ntchito ikuyenda bwino kwa nthawi yayitali. Makasitomala amapindula ndi kuchepa kwa kukonza ndi kudalirika. Miyezo yapamwamba imatetezanso mbiri ya kampani ndi chidaliro cha makasitomala.
Kuyesa magwiridwe antchito ndi gawo lomaliza lowongolera khalidwe. Gulu lililonse lopanga limayesedwa mokwanira. Mapanelo amaundana pa −30 °C kwa maola 24. Akatswiri amasuntha mapanelo nthawi yomweyo kupita kumalo otentha a 60 °C. Oyang'anira amawona ming'alu, kusintha, kapena kugawikana.
Kuyesa kwa kutentha kumeneku kumatsanzira mikhalidwe yoopsa yogwirira ntchito. Mapanelo ayenera kukhala okhazikika pakasinthasintha kutentha mwachangu. Kuyesa kopambana kumatsimikizira kusankha zinthu ndi kuwongolera bwino njira. Mapanelo oyenerera okha ndi omwe amafika pamsika.
Kudzera mu kusankha zinthu mosamala, kupanga molondola, komanso kuyesa mwamphamvu, opanga amaonetsetsa kuti mapanelo odalirika osungiramo zinthu zozizira. Mapanelo abwino kwambiri amateteza katundu, amachepetsa kugwiritsa ntchito mphamvu, komanso amathandizira ntchito za unyolo wozizira kwa nthawi yayitali.
