Sei paine purasitiki yekuputira mukati mearuminiyamu magaba?

Magaba eAluminium ari kwese kwese - kubva pasoda yaunofarira kusvika kune zvinwiwa zvine simba uye mabhodhoro anotonhora emumagaba. Asi waiziva here kuti imwe neimwe yemagaba echinwiwa chealuminium inovanza chimwe chinhu chisingaoneki mukati? Haisi simbi chete yakabata chinwiwa chako. Pane chidimbu chepurasitiki - uye chinoita basa rakakura kudarika zvinofungwa nevanhu vazhinji.

Chinyorwa ichi chinoongorora kuti sei magaba ealuminium akaiswa mapurasitiki, zvinhu zvipi zvinoshandiswa, kana zvakachengeteka, uye zvinorevei pakudzokorodza uye hutano hwako.

Chii chinonzi Coating Mukati meAluminium Can?

Nepo aruminiyamu ichiita seyakachena uye simbi kunze, mukati memagaba mazhinji mune yakajeka kana zvishoma tinted epoxy coating. Iyi firimu yakanyanya kutetepa - ingori 1 kusvika 10 microns gobvu - inopfapfaidzwa mukati megaba kuita chinodzivirira pakati pesimbi nechinwiwa.

Muindasitiri yemagaba, iyi inonzi 'lacquer', uye inowanzo gadzirwa kubva mupurasitiki-based zvinhu senge epoxy resin, vinyl, kana acrylic. Kunyangwe isingaonekwe uye inowanzo furatirwa, uku kupfekedza ndechimwe chezvakanyanya kugadzirwa zvikamu zvegaba rakajairwa.

Sei Aluminium Cans Achida Plastic Coating?

Pakutanga kuona, aruminiyamu inogona kuita sesimbi yakasimba, isina-reactive - yakanakira kurongedza chikafu uye zvinwiwa. Asi muchokwadi, aluminium ikemikari inoshanda zvakanyanya, kunyanya kana ikasangana nemamwe maasidhi, munyu, uye zvinochengetedza zvinowanzowanikwa muzvinwiwa zvemazuva ano uye chikafu chakagadzirwa.

Sodas, zvinwiwa zvesimba, zvinwiwa zvemichero, zvinwiwa zvemitambo, uye kunyange mamwe mvura ane flavouted kazhinji ane citric acid, phosphoric acid, kana yakakwirira chloride mazinga - izvo zvese zvinogona kukonzeresa ngura muaruminiyamu isina chinhu. Dai pasina chinodzivirira mukati megaba, zvinwiwa izvi zvaizotanga kuputsa simbi mukati memazuva. Zvakaguma nei? Metallic flavour, kurasikirwa kwegasi, kuderera kwechimiro chechimiro, kudonhedza, uye mune zvakanyanyisa zviitiko, kunyangwe micro-perforations inotungamira mukutadza kwechigadzirwa uye kuparara.

Kuti vadzivise izvi zvose, vagadziri vanoisa chidimbu chitete chepurasitiki, inozivikanwawo selacquer, mukati memadziro emukati. aluminium magaba . Iyi nhanho inotamba akawanda akakosha mabasa - kwete rimwe chete. Ngativaparadze.

Mienzaniso Yenyika Yechokwadi yeNjodzi dzeCorrosion

Kunyangwe zvinwiwa zvinoita kunge zvakapfava seDiet Coke zvinogona kutyisa zvinoshamisa nekuda kwezvakagadzirwa zvinotapira uye acidic zvemukati. Pasina liner inodzivirira, gaba resoda yekudya rinogona kukanganisa kubva mukati mukati mevhiki. Majusi emichero, kunyanya aya anobva mumichero yecitrus, ane acidic zvakanyanya uye haagare kwenguva refu mugaba realuminium.

Zvimwe zvinwiwa zvesimba zvine hutsinye hwemakemikari zvekuti hapana chifukidziro chiripo chinogona kudzivirira zvizere gaba kubva pakuratidzwa kwenguva refu. Nechikonzero ichi, mamwe magadzirirwo anogona kugadziridzwa kana kuiswa mune mamwe midziyo, senge mabhodhoro egirazi kana mabhokisi akawanda.

Wadii Kushandisa Thicker Aluminium Pane?

Mumwe anogona kushamisika: wadii kungoshandisa aruminiyamu yakakora kuti utsungirire ngura? Mhinduro iri mumutengo, uremu, kusimba, uye kugona kugadzira. Magaba echinwiwa anogadzirwa nemabhiriyoni - neavhareji anogona kugadzirwa achishandisa zvishoma semagiramu gumi nemana ealuminium. Kuwedzera ukobvu kwaizoita kuti magaba awedzere kurema uye kushomeka eco-hushamwari, kuderedza chiyero chekudzokorora, uye kuwedzera zvakanyanya mutengo wekugadzira.

Pane kudaro, iyo indasitiri inovimba nepamusoro-yekuita machira, ayo anopa kuchengetedzwa kunoshanda pane chikamu chidiki chechinhu uye mutengo. Aya machira anoita kuti zvikwanise kushandisa ultra-lightweight, thin-walled aluminium, iyo inoramba yakasimba chete nekuda kwemukati liner.

Iyo Coating Inopfuura Kungoita Chipingamupinyi - Ihurongwa

Chinoita kuti izvi zvinyanye kunakidza ndechekuti kuputira kwepurasitiki hakusi 'saizi imwe inokodzera zvese.' Rudzi rwega rwechinwiwa runoda coating yakanyatsogadzirwa zvichienderana nemakemikari acho. Semuyenzaniso:

● Zvokudya zvematomatisi zvinoda mabhanhire asingasviki acid uye anodzivirira mavara.

● Doro rakapfava pachigaba asi richiri kuda mabhanhire kudzivirira shanduko yekunaka uye kurasikirwa kweCO₂.

● Michero yakaita serhubarb inoita ngura zvekuti inoda kusvika paturu nhatu dzelacquer inodzivirira.

Zvese izvi zvinosimbisa chokwadi chekuti mukati mekupfekedza hachisi chinhu chidiki chekuwedzera, asi chikamu chakakosha chemazuva ano emagaba echinwiwa chealuminium - chakakosha pakushanda kwavo, kuchengeteka, uye kutengeserana.

Ndezvipi Zvishandiso Zvinoshandiswa Mukuvhara?

Zvizhinji zvezvipfeko zvinogadzirwa kubva epoxy resins, kazhinji inotorwa kubva kuBisphenol A (BPA ). BPA inobatsira kugadzira yakasimba, inochinjika, uye inonamira dhizaini inomira kupikisa kudzvanywa uye acidity. Nekudaro, nekuda kwekukura kunetseka kwehutano, vagadziri vazhinji vatanga kupa BPA-Yemahara dzimwe nzira - kunyangwe izvi zvingave zvine makemikari akafanana seBPS kana BPF.

Mhando dzeakajairika coatings:

● Epoxy resins (BPA-based) - Yakawanda, kunyanya kunwa carbonated.

● Vinyl kana acrylic polymers - Inoshandiswa kune mamwe magaba echikafu kana BPA-isina label.

● Oleoresin coatings - Plant-based, inoshandiswa mune imwe organic product mitsara.

Rudzi rwechinwiwa chega chega kazhinji rune tsika yekupfekedza fomula. Semuyenzaniso:

● Magaba edoro haadi kuvharwa zvishoma nekuti mapuroteni ari mudoro anoita seanopedza mweya wekufema.

● Muto wematomatisi nemagaka anoda mabhachi akasimba asingapindi acid.

● Chokoreti nenyama zvinoda mabhanhire anodzivirira kuchinja kunaka kana kubatsira kuti zvokudya zvipere nyore.

Iyo Coating Yakachengeteka Kune Vatengi?

Apa ndipo panonetsa musoro wenyaya.

Chii Chinonzi BPA uye Nei Ichi Chiremera?

Bisphenol A (BPA) ikemikari yemaindasitiri inoshandiswa mumapurasitiki akawanda uye resins, kusanganisira can linings. Iyo endocrine disruptor, zvinoreva kuti inogona kutevedzera kana kukanganisa mahomoni. Zvidzidzo zveSainzi zvakabatanidza BPA ne:

● Hosha dzokubereka nadzo

● Kenza yemazamu neprostate

● Kufutisa nemaitiro

Kunyangwe BPA-Yemahara magaba anogona kushandisa makomisheni akafanana seBPS, ayo anoratidza inofananidzwa eestrogenic chiitiko. Mune mamwe mazwi, kushandura kemikari imwe kune imwe hazvirevi nguva dzose kuti yakachengeteka.

Zvisinei nekunetsekana uku, masangano anodzora anosanganisira FDA neEU vezvekuchengetedza chikafu vakati huwandu hweBPA hunotamira muchikafu kana zvinwiwa idiki zvakanyanya uye mukati 'yakachengeteka' mazinga ekuratidzwa.

Nekudaro, mamwe masayendisiti nevatengi vanosarudza kuitamba zvakachengeteka nekumisa chikafu chemumagaba nechinwiwa, kunyanya kuvana kana vakadzi vane pamuviri.

Iyo Plastic Coating Inokanganisa Kudzokorodza?

Sezvineiwo, kwete. Pasinei nemapuranga epurasitiki, zvigaba zvealuminium zvichiri chimwe chezvinhu zvinogadziriswa zvakare pasi pano. Heino chikonzero:

● Panguva yekudzokororazve, makeni anodziiswa kusvika kuzviuru zvemadhigirii.

● Purasitiki, ingi, uye coating zvinotsva kana kuti zvinokweshwa, zvichisiya aluminum chaiyo.

● Iyo aruminiyamu yakadzokororwa inogona kushandiswa zvakare nekusingaperi pasina kurasikirwa kwemhando.

Enzanisa izvo nemabhodhoro epurasitiki kana zvakasanganiswa-zvinhu kurongedza, uye aruminiyamu inokunda mune zvese kusimba uye kuchengetedza simba.

Unofanira Kunetseka Nezve 'BPA-Yemahara' Zvikumbiro?

Kana gaba rikati 'BPA-Yemahara', hazvireve kuti harina makemikari. Zvinongoreva kuti mugadziri akashandisa imwe kemikari - uye dzimwe nguva kutsiva ikoko hakuna kuongororwa zvizere nezvehutano hwenguva refu.

Mazano mashoma esarudzo dzakachengeteka:

● Shandisa zvigubhu zvegirazi kana zviripo, kunyanya zvinhu zvine acidic zvakaita sematomatisi kana muto wemichero.

● Deredza zvokudya/zvinwiwa zvomumagaba zuva nezuva kana uchityira kuti uchange uchigara kwenguva refu.

● Usapisa chikafu mugaba - kudziya kunowedzera kutama kwemakemikari.

● Tarisa makeni akanyorwa neresin codes 3 kana 7 - izvi zvinowanzobatanidza BPA kana mapurasitiki akafanana.

Mhedziso

Iyo yekuputira epurasitiki mukati memagaba ealuminium chikamu chakakosha chekurongedza kwemazuva ano - kuve nechokwadi chekuti zvinwiwa zvedu zvinogara zviri zvitsva, zvakachengeteka, uye zvinonaka. Asi zvinhu zvakashandiswa, kunyanya BPA, zvakamutsa hutano uye kunetsa kwezvakatipoteredza.

Sezvo tsvagiridzo ichienderera mberi, vamwe vagadziri vari kuchinjika kune zvidyarwa-zvakavakirwa kana zvakachengeteka mabhanhire ekugadzira, asi kuzara pachena kuchiri kushomeka. Parizvino, chiyero chinogona kuramba chiri chishamiso chehunyanzvi - kuenzanisa chemistry, engineering, uye nyore.

Uye nepo maaruminiyamu magaba achishandiswazve zvachose, nzira yakachengeteka semutengi kuziva: ziva zvauri kutenga, magadzirirwo azvinoitwa, uye ndedzipi dzimwe nzira dzingaenderana nemararamiro ako.
