Vim li cas thiaj tuaj yeem muaj cov coatings?
Khoom noj khoom haus thiab dej haus cov kaus poom khaws cov saj thiab cov khoom noj muaj txiaj ntsig ntawm lawv cov filling rau ntau xyoo. Raws li qhov tshwm sim ntawm lub sijhawm cia ntev li no, kev sib cuam tshuam ntawm kev ntim khoom thiab cov khoom noj yuav tsum raug txo kom tsawg. Cov kaus poom xws li Epoxy Resin Coatings Drink Package feem ntau yog coated nrog cov organic txheej uas tiv thaiv kev ncaj ncees ntawm cov kaus poom los ntawm cov khoom noj thiab tiv thaiv cov tshuaj tiv thaiv ntawm cov hlau thiab cov khoom noj. Txhawm rau ua kom tiav cov kev cai thiab kev cai lij choj, cov txheej txheem tuaj yeem tiv thaiv cov txheej txheem tsim khoom thiab ua kom tsis muaj menyuam, siv tau rau txhua hom zaub mov thiab dej haus, tiv thaiv kev tsiv teb tsaws tshuaj rau hauv cov zaub mov hauv qhov ntau uas ua rau tib neeg noj qab haus huv, ua raws li lub peev xwm txawm tias tom qab tsis txhob txwm deformation. , tiv thaiv cov zaub mov nruj thiab tiv thaiv cov hlau ntawm cov kaus poom, thiab khaws cov khoom noj thiab tswj nws cov khoom organoleptic ntau xyoo.

Cov yam ntxwv thiab lwm txoj hauv kev rau coatings
Muaj ntau ntau hom kev lag luam muaj peev xwm coatings, tab sis feem ntau ntawm lawv yog raws li ob peb cov txheej txheem tshuaj (Table). Ntau yam khoom siv ntxiv yog siv rau hauv cov txheej txheem, suav nrog cov roj nplua nyeem, cov tshuaj tiv thaiv ua npuas dej, cov nplaum nplaum, hydrochloric acid scavengers, pigments, thiab cov tebchaw uas txhim kho qhov zawv zawg thiab ntim cov txheej txheem abrasion thiab khawb tsis kam.
Epoxy-raws li cov txheej txheem muaj kev lag luam loj tshaj plaws, suav nrog ntau dua 90 feem pua. Txawm li cas los xij, cov tuam txhab lag luam thiab cov khoom lag luam tuaj yeem pib hloov cov txheej txheem epoxy raws li BPA nrog lwm txoj hauv kev los ntawm cov pov thawj toxicological, kev sib tham rau pej xeem, thiab kev txiav txim siab tsis ntev los no. Acrylic thiab polyester yog tam sim no siv los ua thawj tiam lwm txoj rau epoxy txheej. Epoxy txheej ua los ntawm polyolefin thiab tsis muaj BPA kuj tau tsim dua tsis ntev los no.
Paub meej
Epoxy resins tau siv rau hauv ntim khoom noj txij li xyoo 1950s thiab muab cov txheej txheem tiv thaiv cais cov zaub mov thiab dej haus los ntawm cov hlau siv los ua cov kaus poom.1 Yog tias tsis siv epoxy, cov hlau tuaj yeem corrode thiab ua rau cov kab mob nkag mus rau hauv cov kaus poom. Qhov no tuaj yeem ua rau muaj kev nyab xeeb ntawm lawv cov ntsiab lus nrog rau qhov tshiab thiab kev noj haus ntawm cov zaub mov. Cov kaus poom uas muaj epoxy tuaj yeem muaj lub neej txee ntev dua, yog li cov neeg siv khoom tuaj yeem khaws cov khoom noj rau lub sijhawm ntev. Epoxy resins tseem tso cai rau cov zaub mov hauv zos raws caij nyoog xa tawm txhua xyoo thaum pab khaws cov saj, kev ntxhib los mos thiab xim.
Epoxy resins yog thawj zaug siv los npog steel thiab txhuas cov kaus poom hauv xyoo 1950s. Lawv tau dhau los ua cov khoom siv dav siv ntau tshaj plaws vim lawv txoj kev ruaj ntseg, kev tiv thaiv kev ua haujlwm, thiab cov yam ntxwv thev naus laus zis. Feem ntau ntawm epoxy txheej yog tsim los ntawm kev sib xyaw bisphenol A (BPA, CAS 80-05-7) nrog epichlorohydrin los tsim epoxy resins nrog bisphenol A-diglycidyl ether. Epoxy-phenolic txheej yog cov pab pawg tseem ceeb tshaj plaws ntawm ntau qhov sib xyaw epoxy uas tau tsim. Epoxy amines, acrylates, thiab anhydrides yog qee qhov piv txwv ntawm lwm cov khoom sib xyaw.
Bisphenol A (BPA) yog siv los ua epoxy resins. Epoxy Resin Coatings Drink Package ua nrog BPA tsim kev tiv thaiv hauv cov thawv hlau los pab tiv thaiv cov khoom noj hauv kaus poom kom tsis txhob lwj lossis muaj kab mob los yog xeb. Epoxy resins siv hauv ntim khoom noj tau raug pom zoo rau ntau xyoo los ntawm US Food and Drug Administration (FDA), European Food Safety Authority (EFSA), thiab ntau lwm lub koom haum tseem ceeb thoob ntiaj teb. FDA hais tias BPA muaj kev nyab xeeb nyob rau theem tam sim no tshwm sim hauv cov khoom noj los ntawm cov ntawv thov zaub mov xws li hlau tuaj yeem coatings.7 Tsuas yog feeb seem ntawm BPA tseem nyob hauv epoxy resin thiab yuav hnov mob thaum lub sij hawm kho los yog yuav embedded thiab immobilized rau hauv. cov kho resin.
