Matumba oletsa kutentha kwambiri ali ndi mawonekedwe oti amapakira nthawi yayitali, amasungidwa bwino, amateteza mabakiteriya, amachotsa kutentha kwambiri, ndi zina zotero, ndipo ndi zinthu zabwino zopakira. Ndiye, ndi zinthu ziti zomwe ziyenera kusamalidwa pankhani ya kapangidwe kake, kusankha zinthu, ndi luso? Katswiri wopanga ma paketi osinthasintha PACK MIC adzakuuzani.
Kapangidwe ndi kusankha zinthu za thumba loletsa kutentha kwambiri
Pofuna kukwaniritsa zofunikira pakugwira ntchito kwa matumba oteteza kutentha kwambiri, gawo lakunja la kapangidwe kake limapangidwa ndi filimu ya polyester yamphamvu kwambiri, gawo lapakati limapangidwa ndi zojambulazo za aluminiyamu zokhala ndi mawonekedwe oteteza kuwala komanso mpweya, ndipo gawo lamkati limapangidwa ndi filimu ya polypropylene. Kapangidwe ka magawo atatu kamakhala ndi PET/AL/CPP ndi PPET/PA/CPP, ndipo kapangidwe ka magawo anayi kamakhala ndi PET/AL/PA/CPP. Makhalidwe a magwiridwe antchito amitundu yosiyanasiyana ya mafilimu ndi awa:
1. Filimu ya Mylar
Filimu ya polyester ili ndi mphamvu zambiri zamakaniko, kukana kutentha, kukana kuzizira, kukana mafuta, kukana mankhwala, chotchinga mpweya ndi zina. Kukhuthala kwake ndi 12um /12microns ndipo kungagwiritsidwe ntchito.
2. Cholembera cha aluminiyamu
Cholembera cha aluminiyamu chili ndi chotchinga chabwino kwambiri cha mpweya komanso kukana chinyezi, kotero ndikofunikira kwambiri kusunga kukoma koyambirira kwa chakudya. Chitetezo champhamvu, chomwe chimapangitsa kuti phukusili lisavutike ndi mabakiteriya ndi nkhungu; mawonekedwe okhazikika kutentha kwambiri komanso kotsika; magwiridwe antchito abwino a mthunzi, kuthekera kowunikira kwambiri kutentha ndi kuwala. Chingagwiritsidwe ntchito ndi makulidwe a 7 μm, ndi mabowo ochepa momwe zingathere, komanso dzenje laling'ono momwe zingathere. Kuphatikiza apo, kusalala kwake kuyenera kukhala kwabwino, ndipo pamwamba pake payenera kukhala opanda mawanga amafuta. Kawirikawiri, zojambula za aluminiyamu zapakhomo sizingakwaniritse zofunikira. Opanga ambiri amasankha zinthu zopangidwa ndi zojambula za aluminiyamu zaku Korea ndi Japan.
3. Nayiloni
Nayiloni sikuti imangokhala ndi zinthu zabwino zotchinga, komanso ndi yopanda fungo, yopanda kukoma, yopanda poizoni, komanso yolimba kwambiri. Ili ndi kufooka kotero kuti siimalimbana ndi chinyezi, choncho iyenera kusungidwa pamalo ouma. Ikangoyamwa madzi, zizindikiro zake zosiyanasiyana zogwirira ntchito zimachepa. Kukhuthala kwa nayiloni ndi 15um (15microns). Itha kugwiritsidwa ntchito nthawi yomweyo. Mukapaka lamination, ndi bwino kugwiritsa ntchito filimu yothira mbali zonse ziwiri. Ngati si filimu yothira mbali zonse ziwiri, mbali yake yosathira iyenera kupakidwa ndi aluminiyamu kuti itsimikizire kuti imagwira ntchito bwino.
4. Polypropylene
Filimu ya polypropylene, yomwe ndi gawo lamkati la matumba oteteza kutentha kwambiri, sikuti imangofunika kusalala bwino, komanso ili ndi zofunikira kwambiri pa mphamvu yake yokoka, mphamvu yotseka kutentha, mphamvu yokoka komanso kutalika kwake ikagwa. Zinthu zochepa zapakhomo zokha ndi zomwe zingakwaniritse zofunikira. Imagwiritsidwa ntchito, koma zotsatira zake sizofanana ndi zopangira zomwe zimatumizidwa kunja, makulidwe ake ndi ma microns 60-90, ndipo mtengo wochizira pamwamba ndi woposa 40dyn.
Pofuna kuonetsetsa kuti chakudya chili bwino m'matumba oteteza kutentha kwambiri, phukusi la PACK MIC limakupatsani njira zisanu zowunikira phukusi apa:
1. Kuyesa kusalowa mpweya mu thumba lolongedza
Pogwiritsa ntchito mpweya woponderezedwa komanso kutulutsa madzi m'madzi kuti ayesere momwe zinthu zimatsekedwera, momwe matumba opakira zinthu amatsekedwera amatha kuyerekezeredwa bwino ndikuyesedwa kudzera mu mayeso, zomwe zimapereka maziko odziwira zizindikiro zaukadaulo zoyenera kupanga.
2. Kukaniza kuthamanga kwa thumba la phukusi, kukana kugwa kwa ntchitomayeso.
Poyesa kukana kwa kupanikizika ndi kukana kugwa kwa thumba losagwira kutentha kwambiri, kukana kuphulika ndi chiŵerengero cha kukana panthawi ya kusintha kwa zinthu zitha kulamulidwa. Chifukwa cha kusintha kwa zinthu nthawi zonse pakusintha kwa zinthu, kuyesa kupanikizika kwa phukusi limodzi ndi kuyesa kutsika kwa bokosi lonse la zinthu kumachitika, ndipo mayeso angapo amachitika m'njira zosiyanasiyana, kuti afufuze bwino momwe kupanikizika ndi kutsika kwa zinthu zomwe zapakidwa ndikuthetsa vuto la kulephera kwa zinthu. Mavuto omwe amabwera chifukwa cha kusokonekera kwa ma CD panthawi yonyamula kapena yoyendera.
3. Kuyesa mphamvu ya makina a matumba obwebweta kutentha kwambiri
Mphamvu ya makina ya zinthu zopakira imaphatikizapo mphamvu yopakira yophatikizana ya zinthuzo, mphamvu yotsekera kutentha, mphamvu yomangirira, ndi zina zotero. Ngati chizindikiro chozindikira sichingakwaniritse muyezo, n'zosavuta kusweka kapena kusweka panthawi yopakira ndi mayendedwe. Choyesera cha tensile chapadziko lonse chingagwiritsidwe ntchito molingana ndi miyezo yoyenera yadziko ndi mafakitale, komanso njira zodziwika bwino zodziwira ndikudziwa ngati chili choyenerera kapena ayi.
4. Kuyesa magwiridwe antchito otchinga
Matumba oteteza kutentha kwambiri nthawi zambiri amakhala ndi zinthu zopatsa thanzi kwambiri monga nyama, zomwe zimasungunuka mosavuta ndikuwonongeka. Ngakhale mkati mwa nthawi yosungiramo zinthu, kukoma kwawo kumasiyana malinga ndi masiku osiyanasiyana. Kuti zinthu zikhale bwino, zinthu zotchinga ziyenera kugwiritsidwa ntchito, chifukwa chake mayeso okhwima a mpweya ndi chinyezi ayenera kuchitika pa zinthu zopakira.
5. Kuzindikira zotsalira za zosungunulira
Popeza kusindikiza ndi kuphatikiza ndi njira ziwiri zofunika kwambiri popanga kuphika kotentha kwambiri, kugwiritsa ntchito solvent ndikofunikira pakusindikiza ndi kuphatikiza. solvent ndi mankhwala a polima okhala ndi fungo linalake lopweteka ndipo ndi lovulaza thupi la munthu. Zipangizo, malamulo ndi malamulo akunja ali ndi zizindikiro zowongolera kwambiri za zosungunulira zina monga toluene butanone, kotero zotsalira za zosungunulira ziyenera kupezeka panthawi yopanga kusindikiza zinthu zomalizidwa pang'ono, zinthu zomalizidwa pang'ono ndi zinthu zomalizidwa kuti zitsimikizire kuti zinthuzo ndi zathanzi komanso zotetezeka.
