Chiyambi cha zipangizo zodziwika bwino za matumba opaka vacuum

Matumba opaka vacuumPakugwiritsa ntchito kwathu tsiku ndi tsiku, mabanja ambiri amagwiritsa ntchito Phukusi la Vacuummatumba okalamba oti mupake chakudya kuti mukwaniritse cholinga chowonjezera nthawi yosungira chakudya. Zinthu zomwe zili mu thumba la vacuum zimakhudza mwachindunji momwe limagwirira ntchito, chiwonetsero chotsatira cha vacuum tiphunzira za zinthu ndi mawonekedwe a thumba la vacuum.

Zipangizo zophikira vacuum zomwe zimagwiritsidwa ntchito kwambiri pa chakudya zili ndi magulu awa:

1, poliyesitala matumba otayira mpweya:

Polyester ndi mawu ofala a ma polima omwe amapezeka ndi polyol ndi polyacid polycondensation. Amatanthauza polyethylene terephthalate (PET), polyester (PET) vacuum bag ndi thumba lopanda utoto komanso lowonekera bwino, lowala, lochokera ku polyethylene terephthalate ngati zinthu zopangira, pogwiritsa ntchito njira yotulutsira mu pepala lokhuthala, kenako ndi kutambasula mbali ziwiri zopangidwa ndi thumba lokhuthala. Makhalidwe abwino kwambiri a makina, kulimba kwambiri, kuuma ndi kulimba, kukana kubowola, kukana kukangana, kukana kutentha kwambiri ndi kotsika, kukana mankhwala, kukana mafuta, kukana mpweya komanso kusunga kukoma kwabwino, ndi chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri popanga thumba lokhuthala. Kawirikawiri amagwiritsidwa ntchito popanga zinthu zonyamula nthunzi, kuthamanga kwa mpweya kumakhala bwino.

2, thumba la nayiloni losambitsira mpweya:

Chikwama cha vacuum cha nayiloni (PA) ndi thumba lolimba kwambiri la vacuum, lowonekera bwino, ndipo lili ndi kuwala bwino, mphamvu yokoka, mphamvu yokoka ndi yayikulu, komanso limalimbana bwino ndi kutentha, kuzizira, kukana mafuta ndi zosungunulira zachilengedwe, kukana kukwawa, kukana kubowoka ndikwabwino kwambiri, komanso chotchinga mpweya chofewa kwambiri, choyenera kulongedza zinthu zolimba, monga chakudya chamafuta ambiri, zinthu za nyama, chakudya chokazinga, chakudya chodzaza ndi vacuum, chakudya chophikira, ndi zina zotero.

Kutengera nayiloni Matumba Osambitsira Madzi Zitha kupangidwa kuchokera ku matumba a nayiloni opangidwa ndi zinthu zambiri komanso matumba a vacuum okhala ndi zigawo zambiri.

Matumba a nayiloni opangidwa makamaka ndi PET/PE, PVC/PE, NY/PVDC, PE/PVDC, PP/PVDC, kusiyana kwakukulu pakati pa chikwama chophatikizana ndipo njirayi nthawi zambiri imakhala ndi gawo lapansi, guluu wopaka laminating, zipangizo zotchingira, zipangizo zotsekera kutentha, zosindikizira ndi zotetezera ndi zinthu zina.

Chikwama chachikulu cha vacuum chokhala ndi zigawo zambiri ndi nayiloni, chopangidwa ndi PA, EVOH ndi PE, PP, TIE ndi ma resin ena, pogwiritsa ntchito kapangidwe kofanana kapena kosagwirizana. Pamene PA, EVOH idalumikizana, sikuti imangowonjezera kwambiri mpweya ndi kukoma kwa chotchinga, mphamvu ya peel yophatikizika, kukana chilengedwe komanso nthawi yosungiramo zinthu zatsopano. Popanda kuipitsa mpweya, chotchinga chachikulu, ntchito yamphamvu, mtengo wotsika, chiŵerengero chochepa cha mphamvu, mphamvu yayikulu, kapangidwe kosinthasintha ndi zina zotero, zimapangitsa kuti njira yopangira zinthu zopangira chakudya ikhale yopanda kuipitsa mpweya.

3, Chikwama cha PE chotsukira mpweya:

Polyethylene (polyethylene, PE yochepa) ndi utomoni wa thermoplastic wopangidwa ndi polymerization ya ethylene. Wowonekera bwino kuposa nayiloni, womveka bwino, wopepuka, wokhala ndi chotchinga cha mpweya wabwino, chotchinga mafuta komanso mphamvu zosungira fungo labwino. Sikoyenera kugwiritsidwa ntchito kutentha kwambiri komanso mufiriji, ndipo mtengo wake ndi wotsika mtengo kuposa wa nayiloni. Nthawi zambiri amagwiritsidwa ntchito pazinthu wamba za thumba la vacuum popanda zofunikira zapadera.

4, thumba losakira la aluminum zojambulazo:

Chikwama cha vacuum chopangidwa ndi aluminiyamu-pulasitiki (PET/AL/PE kapena PET/NY/AL/PE kapena PET/NY/AL/CPP), chomwe ndi gawo lalikulu la zojambulazo za aluminiyamu, chopanda mawonekedwe, choyera ngati siliva, chopanda kuwala, chopanda kuwala, chotchinga bwino, chotseka kutentha, choteteza kuzungulira, cholimba kutentha kwambiri, cholimba kutentha pang'ono, cholimba mafuta, chosunga fungo; chopanda poizoni komanso chopanda kukoma; chofewa ndi zinthu zina. Choyenera makina akuluakulu olondola ndi zida, zopangira mankhwala, zosakaniza zamankhwala, zotetezera chinyezi, zopepuka, zopaka vacuum. Kapangidwe kake ka magawo anayi, kokhala ndi ntchito yabwino yotchinga madzi ndi mpweya. Chikwama cha vacuum chopangidwa ndi aluminiyamu chimagwiritsidwa ntchito kwambiri mu chakudya, zamagetsi, mankhwala ndi mafakitale ena, chifukwa zojambulazo za aluminiyamu zokha ndi zodula kwambiri, kotero mtengo wa vacuum udzakhala wokwera.

Zomwe zili pamwambapa ndi chiwonetsero cha vacuum chomwe chafotokozedwa mwachidule pa matumba opaka utsi Zipangizo zomwe zimagwiritsidwa ntchito kwambiri komanso mawonekedwe oyamba, ndikukhulupirira kuti ndikatha kuwerenga abwenzi ambiri posankha matumba awoawo osungira zinthu, adzamvetsetsa bwino izi, akufuna kudziwa zambiri, takulandirani kuti mutilankhule.
