Kodwa bewazi yini ukuthi ngalinye lalawa mathini esiphuzo e-aluminium lifihla okuthile okungabonakali ngaphakathi? Akuyona nje insimbi ebamba isiphuzo sakho. Kunongqimba oluncane lwepulasitiki - futhi ludlala indima enkulu kunalokho abantu abaningi abakuqaphelayo.

Lesi sihloko sihlola ukuthi kungani amathini e-aluminium efakwe ulayini wepulasitiki, yiziphi izinto ezisetshenziswayo, ukuthi ziphephile yini, nokuthi kusho ukuthini lokhu ekugayweni kabusha kanye nempilo yakho.

Iyini I-Coating Ngaphakathi Kwe-Aluminium Can?

Nakuba i-aluminium ibukeka ihlanzekile futhi iyinsimbi ngaphandle, ngaphakathi kwamathini amaningi kunembobo ye-epoxy ecacile noma enombala ogqamile. Le filimu ezacile kakhulu - ugqinsi lwama-microns angu-1 kuye kwayi-10 - ifafazwa ngaphakathi kwekani ukuze yakhe umgoqo wokuvikela phakathi kwensimbi nesiphuzo.

Embonini yamathini, lokhu kubizwa ngokuthi 'i-lacquer', futhi ngokuvamile yenziwa ngezinto ezisekelwe epulasitiki njenge-epoxy resin, i-vinyl, noma i-acrylic. Naphezu kokungabonakali futhi ngokuvamile ukunganakwa, lokhu kunamathela kungenye yezingxenye eziklanywe kakhulu zekani elijwayelekile.

Kungani Amathini E-Aluminium Edinga I-Plastic Coating?

Uma uthi nhlá, i-aluminium ingase ibonakale njengensimbi eqinile, engasasebenzi - ilungele ukupakisha ukudla neziphuzo. Kodwa empeleni, i-aluminium iyasebenza kakhulu ngamakhemikhali, ikakhulukazi uma ihlangana nama-acid athile, usawoti, nezivimbelakuvunda ezivame ukutholakala eziphuzweni zesimanje kanye nokudla okugayiwe.

Amasoda, iziphuzo zamandla, amajusi ezithelo, iziphuzo zezemidlalo, ngisho namanzi anezinongo ngokuvamile aqukethe i-citric acid, i-phosphoric acid, noma amazinga aphezulu e-chloride - konke okungase kubangele ukugqwala ku-aluminium engenalutho. Ukube besingekho isithiyo sokuzivikela ngaphakathi kwekani, lezi ziphuzo bezizoqala ukudiliza insimbi phakathi nezinsuku. Umphumela? Ukunambitheka kwe-metallic, ukulahleka kwegesi, ubuqotho besakhiwo buthaka, ukuvuza, futhi ezimeni ezimbi kakhulu, ngisho nokubhoboza okuncane okuholela ekuhlulekeni nokonakala komkhiqizo.

Ukuvimbela konke lokhu, abakhiqizi bafaka ungqimba oluncane lwe-plastic coating, eyaziwa nangokuthi i-lacquer, ezindongeni zangaphakathi. amathini e-aluminium . Lesi sendlalelo sidlala izindima ezibalulekile eziningi - hhayi eyodwa kuphela. Masizihlukanise:

Umsebenzi	Inhloso
Ukumelana Nokugqwala	Ivimbela ama-asidi nosawoti ekuphenduleni kanye nokwehlisa isithunzi se-aluminium

Lezi zembatho zenza kube nokwenzeka ukusebenzisa i-ultra-lightweight, i-aluminium enezindonga ezincane, ehlala iqinile kuphela ngenxa yomugqa wangaphakathi.

I-Coating Ingaphezu Kwesithiyo Nje — Iwuhlelo

Okwenza lokhu kuthakazelise nakakhulu ukuthi ukufakwa kwepulasitiki akukona 'usayizi owodwa ulingana konke.' Uhlobo ngalunye lwesiphuzo ludinga ukunamathela okuklanywe ngokukhethekile okusekelwe kumakhemikhali alo. Ngokwesibonelo:

● Ukudla okusekelwe kutamatisi kudinga ukunamathela okumelana ne-asidi kanye ne-stain-resistant.

● Obhiya bathambile ethini kodwa basadinga ukumbozwa ukuze bavimbele ukushintsha kokunambitheka kanye nokulahlekelwa kwe-CO₂.

● Izithelo ezinjenge-rhubarb zigqwala kangangokuthi zifuna izendlalelo ezintathu ze-lacquer yokuzivikela.

Konke lokhu kugcizelela iqiniso lokuthi ukumbozwa kwangaphakathi akusona isengezo esincane, kodwa kuyingxenye eyinhloko yamathini eziphuzo e-aluminium yesimanje - kubalulekile ekusebenzeni kwawo, ukuphepha, nokusebenza kwezohwebo.

Yiziphi Izinto Ezisetshenziswayo Ekukhoneni?

Izindwangu eziningi zethini zenziwe ngama-epoxy resins, ngokuvamile atholakala ku-Bisphenol A (BPA ). I-BPA isiza ukwakha ungqimba oluqinile, oluguquguqukayo, nolunamathelayo olumelana nokucindezela ne-asidi. Kodwa-ke, ngenxa yokukhathazeka kwezempilo okukhulayo, abakhiqizi abaningi sebeqalile ukunikeza ezinye izindlela ze-BPA-Free - nakuba lezi zingaqukatha amakhemikhali afana ne-BPS noma i-BPF.

Izinhlobo zama-coatings ajwayelekile:

● Ama-epoxy resins (asekelwe ku-BPA) - Avame kakhulu, ikakhulukazi iziphuzo ezine-carbonated.

● Ama-polymer e-vinyl noma e-acrylic - Asetshenziselwa amathini okudla athile noma amalebula angenayo i-BPA.

● I-Oleoresin coatings – Isekelwe ezitshalweni, esetshenziswa kweminye imigqa yomkhiqizo wemvelo.

Uhlobo ngalunye lwesiphuzo luvame ukuba nefomula yokwemboza yangokwezifiso. Ngokwesibonelo:

● Amathini kabhiya awadingi ukumbozwa kancane ngenxa yokuthi amaprotheni akubhiya asebenza njengento engokwemvelo yokukhipha umoya-mpilo.

● Amasoso katamatisi namakhukhamba adinga izimbotshana eziqinile ezimelana ne-asidi.

● Ushokoledi nenyama kudinga ukunamathiswa okuvimbela ukushintsha ukunambitheka noma okusiza ukudla kusheleleke kalula.

Ingabe I-Coating Iphephile Kubathengi?

Yilapho isihloko siba nengxabano kakhulu.

Iyini i-BPA futhi Kungani Iphathelene?

I-Bisphenol A (BPA) iyikhemikhali yezimboni esetshenziswa kumapulasitiki amaningi nama-resin, okuhlanganisa nama-linings ethini. Iwukuphazamiseka kwe-endocrine, okusho ukuthi ingalingisa noma iphazamise amahomoni. Ucwaningo lwesayensi luxhume i-BPA ku:

● Izinkinga zokuzala

● Umdlavuza webele nowendlala yesinye

● Ukukhuluphala ngokweqile kanye nezindaba zokuziphatha

Ngisho namathini angenayo i-BPA angase asebenzise izinhlanganisela ezifanayo njenge-BPS, ezibonisa umsebenzi we-estrogenic ofanayo. Ngamanye amazwi, ukushintsha ikhemikhali eyodwa kwelinye akusho ukuthi kuphephe kakhudlwana.

Ngaphandle kwalokhu kukhathazeka, izikhungo ezilawulayo ezihlanganisa i-FDA kanye neziphathimandla zokuphepha kokudla ze-EU zithe inani le-BPA elithuthela ekudleni noma eziphuzweni lincane kakhulu futhi lingaphakathi kwamazinga okuchayeka 'aphephile'.

Nokho, abanye ososayensi nabathengi bakhetha ukuyidlala iphephile ngokunciphisa ukudla okusemathinini neziphuzo, ikakhulukazi ezinganeni noma kwabesifazane abakhulelwe.

Ingabe I-Plastic Coating Ithinta Ukugaywa Kabusha?

Ngenhlanhla, cha. Naphezu kolwelwesi lwepulasitiki, amathini e-aluminium asengenye yezinto ezigaywa kabusha kakhulu eMhlabeni. Nasi isizathu:

● Ngesikhathi sokugaywa kabusha, amathini abaswa abe yizinkulungwane zamadigri.

● Ipulasitiki, uyinki, nezinto ezinamathelayo ziyasha noma zisulwe, kushiye i-aluminium emsulwa.

● I-aluminium egaywe kabusha ingasetshenziswa kabusha unomphela ngaphandle kokulahlekelwa yikhwalithi.

Qhathanisa lokho namabhodlela epulasitiki noma amaphakheji ezinto ezixutshiwe, futhi i-aluminium iwina kukho kokubili ukusimama nokonga amandla.

Ingabe Kufanele Ukhathazeke 'Ngezimangalo Ze-BPA-Zamahhala'?

Uma ikani lithi 'I-BPA-Free', akusho ukuthi ayinamakhemikhali. Kusho kuphela ukuthi umkhiqizi usebenzise ikhemikhali ehlukile - futhi kwesinye isikhathi leyo khemikhali ayikakahlolelwa ngokuphelele imiphumela yezempilo yesikhathi eside.

Amathiphu ambalwa wezinketho eziphephile:

● Sebenzisa izitsha zengilazi uma zikhona, ikakhulukazi izinto ezine-asidi njengotamatisi noma amajusi ezithelo.

● Nciphisa ukudla okusemathinini/isiphuzo nsuku zonke uma ukhathazekile ngokuchayeka isikhathi eside.

● Ungakushisi ukudla ethini — ukufudumala kusheshisa ukufuduka kwamakhemikhali.

● Bheka amathini abhalwe amakhodi e-resin 3 noma 7 — lawa maningi amathuba okuthi afake i-BPA noma amapulasitiki afanayo.
