Filimka Baakadaha EVA ee loogu talagalay Kaabayaasha Lagu daro
ZonpakTMFilimka baakadaha EVA waxaa si gaar ah loogu talagalay in lagu sameeyo bacaha yar yar ee caagga lagu daro (tusaale 100g-5000g) oo leh foom-buuxinta-seal (FFS). Waxyaalo kala duwan oo caag ah ama kiimikooyin ah (tusaale peptizer, wakiilka gabowga, wakiilka daawaynta, daaweeyaha dardargeliyaha, saliida habka cinjirka) ayaa caadi ahaan loo isticmaalaa habka isku dhafka caagga, waxaana loo baahan yahay wax yar oo ka mid ah qalabkan dufc kasta. Markaa baakadahan yar-yar waxay ka caawin karaan isticmaaleyaasha walxaha inay kordhiyaan hufnaanta shaqada kana fogaadaan qashinka alaabta. Filimku wuxuu ka samaysan yahay EVA resin (copolymer of ethylene iyo vinyl acetate) kaas oo leh bar dhalaaleed hoose oo gaar ah iyo la jaanqaad wanaagsan oo leh caag ama maaddooyinka resin. Markaa bacaha ay la socdaan agabka ku jira waxaa si toos ah loogu ridi karaa qase. Bacaha ayaa dhalaali doona oo u kala firdhi doona barxadda caagga ah sida walax yar oo waxtar leh.
Filimada leh dhibco dhalaalid oo kala duwan (65-110 darajo Celsius) iyo dhumucdiisuna waxay diyaar u yihiin isticmaalka xaaladaha kala duwan.
