- Kutentha kukana
Kutentha kumaphatikizapo mbali ziwiri.Chimodzi ndi kukana kutentha kwambiri.Pakadali pano, zakudya zambiri zimafunikira kutsekereza kutentha kwambiri, zina zimatsukidwa pa 80-100.° C, pamene ena amatsekeredwa pa 100-135° C. Nthawi yotseketsa imasiyanasiyana, zina zimatengera mphindi 10-20 pomwe zina zimatengera mphindi 40.Ena amasungidwabe ndi ethylene oxide.Zida zosiyanasiyana zimakhala ndi njira zosiyanasiyana zotsekera.Koma zomatira zopanda zosungunulira zosankhidwa ziyenera kukwaniritsa zofunikira za kutentha kwambiri.Thumba silingathe kusokoneza kapena kupunduka pambuyo pa kutentha kwakukulu.Kuphatikiza apo, zinthu zomwe zimachiritsidwa ndi zomatira zopanda zosungunulira ziyenera kupirira kutentha kwambiri kwa 200.° C kapena ngakhale 350° C nthawi yomweyo.Ngati izi sizingakwaniritsidwe, kusindikiza kutentha kwa thumba kumakhala kosavuta ku delamination.
Chachiwiri ndi kukana kutentha kwapansi, komwe kumadziwikanso kuti kukana kuzizira.Zida zambiri zomangira zofewa zimakhala ndi chakudya chozizira, chomwe chimafuna zomatira zopanda zosungunulira kuti zizitha kupirira kutentha kochepa.Pa kutentha kochepa, zipangizo zolimba ndi zomatirazo zimakhala zosavuta kuuma, kuphulika, delamination, ndi fracture.Ngati zochitikazi zikuchitika, zimasonyeza kuti zomatira zosankhidwa sizingathe kupirira kutentha kochepa.
Choncho, posankha zomatira zopanda zosungunulira, kumvetsetsa mwatsatanetsatane ndi kuyesa kukana kutentha ndikofunikira.
3.Zaumoyo ndi Chitetezo
Zomatira zopanda zosungunulira zomwe zimagwiritsidwa ntchito popaka zakudya ndi mankhwala ziyenera kukhala zaukhondo komanso chitetezo.Malamulo okhwima ali m'mayiko osiyanasiyana padziko lonse lapansi.US FDA imayika m'magulu zomatira zomwe zimagwiritsidwa ntchito popanga zinthu zophatikizira zakudya ndi mankhwala monga zowonjezera, kuchepetsa zopangira zomwe zimagwiritsidwa ntchito popanga zomatira ndikuletsa kugwiritsa ntchito zinthu zomwe sizinaphatikizidwe pamndandanda wovomerezeka wazinthu zopangira,Ndipo zida zophatikizika zopangidwa ndi izi. zomatira zimagawidwa m'magulu awo kutentha, kuphatikiza kutentha kwa chipinda, kugwiritsa ntchito mankhwala ophera tizilombo toyambitsa matenda, 122 ° C kugwiritsa ntchito njira yotseketsa nthunzi, kapena 135 ° C komanso kupitilira kutentha kwambiri.Panthawi imodzimodziyo, zinthu zowunikira, njira zoyesera, ndi zizindikiro zaumisiri zopangira zida zimapangidwanso.Palinso zofunikira ndi zoletsa mu muyezo wa GB9685 waku China.Choncho, zomatira zopanda zosungunulira zomwe zimagwiritsidwa ntchito pogulitsa malonda akunja ziyenera kutsata malamulo am'deralo.
4.Kukwaniritsa zosowa zamapulogalamu apadera
Kugwiritsiridwa ntchito kofala kwa zosungunulira zopanda zosungunulira m'mapaketi osinthika kwalimbikitsa kufalikira kwawo kumadera okhudzana.Pakadali pano, pali madera apadera omwe agwiritsidwa ntchito:
4.1 Zosungunulira zaulere za PET zopangira
Mapepala a PET amapangidwa makamaka ndi zida za PET zokhala ndi makulidwe a 0.4mm kapena kupitilira apo.Chifukwa cha makulidwe ndi kusasunthika kwa zinthuzi, ndikofunikira kusankha zomatira zopanda zosungunulira zokhala ndi zomatira zapamwamba komanso zowoneka bwino kuti mupange zinthu izi.Zomaliza zopangidwa ndi mtundu uwu wazinthu zophatikizika nthawi zambiri zimafunikira kupangidwa mosiyanasiyana, zina zomwe zimafunikira masitampu, kotero kuti zofunikira zamphamvu za peel ndizokwera kwambiri.WD8966 yopangidwa ndi Kangda New Equipment ili ndi zomatira zoyambira komanso zopondaponda, ndipo zakhala zikugwiritsidwa ntchito bwino mu PET pepala lophatikizika.
4.2 Zosungunulira zaulere zopanda nsalu zopanda nsalu
Nsalu zosalukidwa zimagwiritsidwa ntchito kwambiri ndipo zimakhala ndi mitundu yosiyanasiyana.Kugwiritsa ntchito nsalu zopanda nsalu m'malo opanda zosungunulira makamaka kumadalira makulidwe a nsalu yopanda nsalu komanso kuchuluka kwa ulusi.Kunena zoona, kukhuthala kwa nsalu yosakhala yolukidwa kumapangitsa kuti ikhale yabwino kwambiri yopanda zosungunulira.Pakadali pano, zomatira zomatira zotentha za polyurethane zotentha zimagwiritsidwa ntchito kwambiri popanga nsalu zopanda zosungunulira zopanda nsalu.
