Mndandanda wa mfundo zamakina ndi chitukuko cha ntchito ya vacuum ma CD zida

Kuyika kwa vacuum ndikutulutsa mpweya m'thumba loyikamo ndikusindikiza zinthuzo kuti zikwaniritse cholinga chosungira kutsitsimuka komanso kusungika kwa nthawi yayitali kwa zinthu zomwe zapakidwa, zomwe ndi zabwino mayendedwe ndi kusungirako.Zida zonyamula vacuum ndi makina omwe atatha kuyika chinthucho mumtsuko, kuyamwa mpweya mkati mwa chidebecho, kufika pa digiri ya vacuum yokonzedweratu (nthawi zambiri pafupifupi 2000 ~ 2500Pa) ndikumaliza kusindikiza.Ikhozanso kudzazidwa ndi nayitrogeni kapena mpweya wina wosakanizika, ndiyeno malizitsani kusindikiza.

Kuyambira m'ma 1940, ukadaulo wonyamula vacuum wawonekera ndikugwiritsidwa ntchito.Mpaka zaka zapakati mpaka kumapeto kwa zaka 50, malo osungiramo vacuum pang'onopang'ono adayamba kugwiritsa ntchito polyethylene ndi mafilimu ena apulasitiki pakuyika.Kumayambiriro kwa zaka za m'ma 1980, ndi chitukuko chofulumira cha malonda ogulitsa ndi kukwezedwa pang'onopang'ono kwa ma CD ang'onoang'ono, teknoloji inagwiritsidwa ntchito ndikupangidwa.Kuyika kwa vacuum ndikoyenera matumba osiyanasiyana a filimu opangidwa ndi pulasitiki kapena matumba a filimu opangidwa ndi aluminiyamu, monga poliyesitala / polyethylene, nayiloni / polyethylene, polypropylene / polyethylene, poliyesitala / aluminium zojambulazo / polyethylene, nayiloni / aluminium zojambulazo / polyethylene, etc.Ndikusintha kosalekeza kwa kuzindikira kwamalingaliro a anthu, kugwiritsa ntchito makina onyamula vacuum kwakopa chidwi chochulukirapo kuchokera kumafakitale monga chakudya, nsalu, ndi zamagetsi.

Mfundo ndi gulu la vacuum ma CD zida

Mapangidwe a zida zonyamula vacuum ndizosiyana, ndipo njira yogawa ndi yosiyana.Nthawi zambiri malinga ndi njira zosiyanasiyana ma CD, zikhoza kugawidwa mu makina extrusion mtundu, intubation mtundu, chipinda mtundu, etc.;malinga ndi momwe zinthu zomwe zapakidwa zimalowera m'chipindacho, zitha kugawidwa m'chipinda chimodzi, chipinda chapawiri, mtundu wa thermoforming, mtundu wa lamba wotumizira, ndi chipinda chowongolera chozungulira.Malingana ndi mtundu wa kayendetsedwe ka kayendetsedwe kake, imatha kugawidwa m'magulu apakati komanso opitirira;malingana ndi ubale wapakati pa zomwe zapakidwa ndi chidebe choyikamo, zitha kugawidwa m'mapaketi a vacuum pakhungu ndi vacuum inflatable ma CD.

Ndi chitukuko chosalekeza cha sayansi ndi ukadaulo komanso kuwongolera kopitilira muyeso kwa moyo wa anthu, kugwiritsa ntchito ukadaulo wapa paketi ya vacuum kudzachulukirachulukira, ndipo mitundu, mawonekedwe, magwiridwe antchito, komanso mtundu wa zida zolongedza vacuum zidzasintha ndikusintha.M'makampani opanga nsalu ndi manja, kuyika kwa vacuum kumatha kuchepetsa kuchuluka kwazinthu ndikuwongolera kulongedza ndi mayendedwe;m'makampani azakudya, ukadaulo wa vacuum ndi kutsekereza kumatha kuletsa kukula kwa bakiteriya, kuchepetsa kuwonongeka kwa chakudya, ndikuwonjezera moyo wa alumali wa chakudya;mu zamagetsi, M'makampani a hardware, zida za hardware zodzaza ndi vacuum zimatha kudzipatula mpweya, kuti zipangizozo zisawonongeke ndi dzimbiri.
