Zihlolwa kanjani izikhwama zepulasitiki? Ziyiniamazinga wokuhlolangezikhwama zepulasitiki ezisetshenziswa ekupakisheni ukudla?
Ukwamukela amazinga kanye nezigaba
1. Izinga lasekhaya lokuhlolwa kwezikhwama zepulasitiki: I-GB/T 41168-2021 Ifilimu eyinhlanganisela yepulasitiki ne-aluminium foil kanye nesikhwama sokupakisha ukudla
2. Ukwahlukanisa
-Ngokwesakhiwo: Izikhwama zepulasitiki zokudla zihlukaniswe nge-Class A kanye ne-Class B ngokuya ngesakhiwo
-Kuhlukaniswa ngokwezinga lokushisa elisetshenziswayo: Izikhwama zepulasitiki zokudla zihlukaniswa ngebanga elibilisayo, izinga lokushisa elilingana nokushisa okuphezulu, kanye nebanga lokushisa eliphakeme lokushisa ngokwezinga lokushisa lokusetshenziswa.
Ukubukeka nobuciko
-Buka ngokubukeka ngaphansi kokukhanya kwemvelo futhi ulinganise ngethuluzi lokulinganisa ngokunemba okungengaphansi kuka-0.5mm:
-Imibimbi: Imibimbi emincane emincane ivunyelwe, kodwa ingeqi ku-5% wendawo yomkhiqizo;
-Ukuklwebheka, ukusha, ukubhoboza, ukunamathela, izinto zangaphandle, ukubola nokungcola akuvunyelwe;
-I-Elasticity ye-roll yefilimu: akukho ukushelela phakathi kwama-rolls wefilimu lapho ihamba;
-Ukuqiniswa okuveziwe kwefilimu: Ukuqinisa obala kancane okungathinti ukusetshenziswa kuvunyelwe;
-Ukungalingani kobuso bokuphela kwefilimu: hhayi ngaphezulu kuka-2mm;
-Ingxenye yesikhwama evala ukushisa iyisicaba, ngaphandle kokuvaleka okuxekethile, futhi ivumela amabhamuza angathinti ukusetshenziswa kwaso.
Ukupakisha/Ukuhlonza/Ukulebula
Iphakethe ngalinye lomkhiqizo kufanele lihambisane nesitifiketi sokuvumelana futhi libonise igama lomkhiqizo, isigaba, imininingwane, izimo zokusetshenziswa (izinga lokushisa, isikhathi), inani, ikhwalithi, inombolo yeqoqo, usuku lokukhiqiza, ikhodi yomhloli, iyunithi yokukhiqiza, ikheli leyunithi yokukhiqiza. , inombolo evamile yokusebenza, njll.
Izidingo zokusebenza ngokomzimba nangokomshini
1. Iphunga elingavamile
Uma ibanga ukusuka kusampula yokuhlola lingaphansi kuka-100mm, yenza ukuhlolwa kokuhogela futhi lingekho iphunga elingavamile.
2.Isixhumi
3.Ukuhlolwa kwezikhwama zepulasitiki - ukuchezuka kosayizi:
3.1 Ukuchezuka kosayizi wefilimu
3.2 Ukuchezuka kosayizi wezikhwama
Ukuchezuka kosayizi wesikhwama kufanele kuhambisane nezinhlinzeko ezisethebula elingezansi. Ububanzi bokuvala ukushisa kwesikhwama buyolinganiswa ngethuluzi lokulinganisa ngokunemba okungengaphansi kuka-0.5mm.
4 Ukuhlolwa Kwesikhwama Sepulasitiki - Izakhiwo Zomzimba Nezomshini
4.1 Amandla okucwecwa kwesikhwama
4.2 Amandla okuvala ukushisa kwesikhwama
4.3 Amandla okuqina, ubunzima obungajwayelekile ngesikhathi sekhefu, amandla okudabula i-engeli yesokudla, kanye nokumelana namandla omthelela we-pendulum
Isitayela sithatha umumo omude we-strip, ubude obungu-150mm nobubanzi obungu-15mm ± 0.3mm. Isikhala phakathi kwezakhiwo zesitayela ngu-100mm ± 1mm, futhi isivinini esinwebekayo sesitayela ngu-200mm/min ± 20mm/min.
4.4 Isikhwama sepulasitiki sokungena komhwamuko wamanzi kanye nokungena komoyampilo
Ngesikhathi sokuhlolwa, indawo yokuthintana yokuqukethwe kufanele ibhekane nohlangothi lwengcindezi ephansi noma uhlangothi oluphansi lokugxila komhwamuko wamanzi, ngezinga lokushisa lokuhlola elingu-38 ° ± 0.6 ° kanye nomswakama ohlobene ongu-90% ± 2%.
4.5 Ukumelana nokucindezela kwezikhwama zepulasitiki
4.6 Ukwehlisa ukusebenza kwezikhwama zepulasitiki
4.7 Ukumelana nokushisa kwezikhwama zepulasitiki
Ngemva kokuhlolwa kokumelana nokushisa, akumele kube nokushintsha kombala okusobala, ukuwohloka, ukuxebuka kwe-interlayer, noma ukuxebuka kokuvala ukushisa nezinye izinto ezingavamile. Lapho uphawu lwesampula luphukile, kuyadingeka ukuthi kuthathwe isampula bese ulenza futhi.
Kusukela ekudleni okusha kuya ekudleni okulungele ukudliwa, kusukela ezinhlamvu kuya enyameni, kusukela ekufakweni komuntu ngamunye kuya emaphaketheni okuthutha, kusukela ekudleni okuqinile kuya ekudleni okuwuketshezi, izikhwama zepulasitiki seziyingxenye yemboni yokudla. Okungenhla kungamazinga nezindlela zokuhlola izikhwama zepulasitiki ezisetshenziswa ekupakisheni ukudla ukuze kuqinisekiswe ukuphepha kokudla.
