Aluminium ntawv nyiajNws muaj cov yam ntxwv ntawm lub ntsej muag du, lub teeb yuag, lub teeb pom kev zoo, tsis yooj yim rau corrode, tsis muaj tshuaj lom, yooj yim rau kev ua, thiab lwm yam, thiab tuaj yeem ua ke nrog cov ntawv thiab cov khoom siv yas sib xyaw ua ke.
Tsis tiav thaum tshav kub kub sealing yog ib qho teeb meem tseem ceeb uas tig mus rau tam sim noaluminium foil ntimkev lag luam. Qhov no feem ntau yog vim qhov tsis zoo los tiv thaiv kev ua qias tuaj thaum tshav kub kub sealing cov khoom ntawm cov khoom sib xyaw ua ke thiab cov khoom siv tsis tsim nyog siv nyob rau hauv cov txheej txheem sealing sab hauv. Nyob rau hauv cov ntaub ntawv no, cov ntsiab lus yog yooj yim to los yog deterioration, uas cuam tshuam rau qhov zoo ntawm cov khoom thiab cov neeg siv khoom.
Kev lag luam nquag nrhiav cov yeeb yaj kiab uas muaj kev sib kis zoo dua thiab ua kom sov sealability. Piv txwv li, LDPE (tsis tshua muaj ntom polyethylene) muaj qhov nruab nrab stain tsis kam tiv thaiv tshav kub sealability, thaum EVA (ethylene vinyl acetate copolymer) muaj qhov zoo stain kuj kub sealability ntawm VA (vinyl acetate) cov ntsiab lus siab dua. Tsis tas li ntawd, LDPE thiab metallocene polymers kuj muaj kev tiv thaiv kev sib kis tau zoo heev. Los ntawm kev siv cov ntaub ntawv no zoo dua los tiv thaiv kev sib kis thaum tshav kub kub sealing zog, sealing kev ua tau zoo ntawm aluminium foil ntim tuaj yeem txhim kho tau zoo, yog li txuas lub txee lub neej ntawm cov khoom thiab txhim kho cov neeg siv khoom.
Txhawm rau daws cov teeb meem no, kev lag luam tau siv ntau yam kev ntsuas. Piv txwv li, raws li cov yam ntxwv ntawm lub tshav kub sealing ntawm cov khoom ntawm lub puab sealing txheej, xaiv qhov tsim nyog ua kub, siab thiab kub sealing lub sij hawm. Tsis tas li ntawd, qhov teeb meem ntawm brittleness thiab brittle breakage ntawm lub foob yog txo los ntawm kev txhim kho qhov saum npoo ntawm lub tshav kub sealing riam, ua rau saum npoo ntawm sealer du, thiab npog nws nrog polytetrafluoroethylene daim ntaub. Nyob rau tib lub sijhawm, xaiv silicone roj hmab ncoo uas tsim nyog hardness kuj yog ib txoj hauv kev zoo los daws qhov teeb meem no.
