Uruhare rw'ingenzi rw'ibikoresho bitera imbaraga mu by'amazi muri filime zipima ibiryo

Mu rwego rw’imikorere y’ibipfunyika by’ibiribwa, aho umutekano, igihe cyo kubibika, n’ubuziranenge bw’ibicuruzwa bihurira, ibintu bigabanya ubuziranenge bw’ibicuruzwa byagaragaye nk’intwari zitari zizwi. Ibi bipfunyika, byakozwe neza cyane kugira ngo bikoreshwe mu mafilime y’ibiryo, bigira uruhare runini mu buzima bw’abaguzi ndetse no mu mikorere myiza y’inganda. Reka turebere hamwe imirimo ine y’ingenzi ituma ibintu bigabanya ubuziranenge bw’ibiryo biba ingenzi mu bipfunyika by’ibiryo bigezweho.

Ubushobozi bwo kwihanganira ubushyuhe: Kurinda firime ziterwa n'ubushyuheGutakaza agaciro

Filimi zikoreshwa mu gutunganya ibiryo, zaba polyethylene (PE) cyangwa polypropylene (PP), zikorerwa ubushyuhe bwinshi (urugero: gusohora, gukaraba) kugeza kuri 230°C.Ibikoresho bigabanya ubushyuhe bw'amazibikora nk'ibirinda ubushyuhe, bigafata ibintu bihumanya ikirere biva mu gihe cy'ubushyuhe. Ubushakashatsi bwakozwe n'Ikigo cy'Ikoranabuhanga mu Gupakira bwagaragaje ko hatabayeho ibintu bitera imbaraga, ingero za filime zagaragaje ko imbaraga zo gukurura zigabanukaho 35% nyuma y'iminota 10 kuri 200°C. Ibinyuranye n'ibyo,firime zifite ubushobozi bwo kubungabunga amaziIfumbire zakoreshejwe zigumana imbaraga zirenga 90% by'umwimerere wazo, zigatuma imiterere yazo ikomeza kuba myiza mu gihe cyo guteka nk'amasahani y'ibiryo ashobora gukoreshwa muri microwave.

Kurenza igihe cyo kumara igihe kirekire: Kugabanya okisidasiyo no kwangirika kwa UV​

Uretse gutunganya, ibintu bigabanya ubushyuhe mu mazi birwanya ibintu bibangamira ibidukikije mu gihe cyo kubibika no kubitwara. Imirasire ya UV n'umwuka wa ogisijeni bishobora gutera ogisijeni mu kirere, bigatuma amashusho aba umuhondo kandi agahinduka umukara. Urugero, mu igerageza ryo kugereranya ku ipaki y'ibirayi, amashusho afite inyongeramusaruro zigabanya ubushyuhe ku kigero cya 25%, nk'uko bipimirwa n'agaciro ka peroxide. Antioxydants zishingiye kuri aside irike mu bintu bigabanya ubushyuhe mu mazi zikuraho ogisijeni, mu gihe ibintu bigabanya ubushyuhe mu mazi nka benzotriazoles birinda amashusho kwangirika mu mirasire, bikarinda ubwiza bw'ibipaki n'agaciro k'intungamubiri z'ibiryo.

Uburyo bwo gutunganya ibintuKongera ubushobozi: Kunoza uburyo bwo gushonga noUbumwe

Abakora ibikoresho bahura n'imbogamizi zo kugera ku bugari bwa firime n'ubuso bungana. Ibikoresho bigabanya ubushyuhe bushonga kugeza kuri 18%, nk'uko raporo z'inganda zibivuga, bigatuma habaho gusohora neza. Uku kunoza ni ingenzi cyane ku miyoboro ikora vuba, aho itandukaniro rya mm 0.1 mu bugari rishobora gutera imyanda myinshi. Mu guteza imbere plasticization ihoraho, ibikoresho bigabanya inenge nk'ihindagurika ry'ubuso n'ubugari bw'ingufu, bigatuma habaho kuzigama ikiguzi no kunoza umusaruro.

Iyubahirizwa ry'amategeko: Guharanira umutekano w'ibiribwa n'umuguziIcyizere

Umutekano w'amafirime yo mu rwego rwo hejuru rw'ibiribwa ushingiye ku kugenzura uburyo bwo kwimuka kw'inyongera. Ibikoresho bigabanya ubushyuhe bw'amazi bigomba gukurikiza amabwiriza akaze, nka US FDA 21 CFR 178.2010 na EU Regulation (EC) No 10/2011. Urugero,ibintu bitera imbaraga bikungahaye kuri calcium-zinc, byemejwe nk'uburyo butari uburozi bushobora gusimbura ibikomoka kuri lisansi gakondo, byubahiriza amahame mpuzamahanga agenga ibiribwa. Igipimo cyabyo kiri hasi cyo kwimuka (≤0.1 ppm ku byuma biremereye) bituma biba byiza cyane mu gupakira ibiryo by'abana bato, aho umutekano ari wo ukomeye.

Imiterere y'ejo hazaza: Udushya mu ikoranabuhanga rituza

Inganda zirimo kubona impinduka mu bijyanye no kubungabunga ibiryo hakoreshejwe ibinyabutabire. Amavuta ya soya yakuwemo ibinyabutabire, akomoka ku bikomoka ku bimera bishobora kongera gukoreshwa, ubu agize 30% by'isoko ry'ibitera imbaraga mu kubungabunga ibidukikije. Abashakashatsi barimo kandi gusuzuma uburyo bwinshi bwo guhuza ubushobozi bwo kubungabunga ibiryo n'ibintu bikora, nk'ubushobozi bwo kurwanya indwara ziterwa n'imiti. Aya majyambere asezeranya kongera gusobanura ibipimo by'umutekano n'ubudahangarwa bw'ibiryo mu gupfunyika.

Mu gusoza, ibintu bigabanya ubushyuhe bw'amazi si inyongeramusaruro gusa, ahubwo ni ibintu by'ingenzi bikingira ubuziranenge bw'ibiribwa, bikoroshya umusaruro, kandi bikubahiriza amategeko. Uko abaguzi bakenera gupakira neza kandi birambye, ibi bintu bikoresha uburyo butandukanye bizakomeza gutera imbere, bigatera imbere mu buryo bushya bwo gupakira ibiribwa.
