Tepi yefirimu yepolyester inogadzirwa nezvinonamira zvinonzwa kudzvanywa (senge zvinonamira zveacrylate) pafirimu yepolyester (PET film) sechinhu chekutanga. Inogona kushandiswa pamidziyo yemagetsi yemidziyo yekutonhodza, mafiriji ekutengeserana, nezvimwewo. Muna 2025, huwandu hwekutengesa kwetepi yefirimu yepolyester hwakawedzera nekuwedzera kwehuwandu hwemidziyo inotumirwa kunze kwenyika nevagadziri, zvichiita 80% yezvinodiwa pagore.
Ndezvipi zvinhu chaizvo zvirimo?
Nekuda kwehunhu hwayo hwakadai sekudzivirira kupisa, kuputira, uye kunamira kwakasimba, tepi yefirimu yepolyester ine mamiriro akasiyana-siyana ekushandiswa mukugadzirwa nekushandiswa kwemafiriji:
(1) Kugadzirisa Zvikamu
Munguva yekubatanidza firiji, inogona kushandiswa kugadzirisa zvinhu zvemukati zvakaita sewaya nemapaipi (senge mapaipi emvura inobuda mufiriji) kudzivirira kuti zvisafambe nekuda kwekuzunguzika panguva yekutakura kana kushandisa.
(2) Dziviriro yekudzivirira kupisa
Zvinhu zvemagetsi (zvakaita sefiriji thermostats uye mota dzinobatanidza waya) zvinoda kugadziriswa kwekudzivirira kupisa. Kushanda kwe polyester film tape kudzivirira njodzi dzekubuda kwemagetsi kana kudonha kwemagetsi.
(3) Rubatsiro rweKuvhara
Pakuisa zvisimbiso zvemasuo kana kusungirira muviri wefiriji, zvinogona kubatsira mukuwedzera kushanda kwekuvhara, kuderedza kubuda kwemhepo inotonhora, uye kuvandudza kushanda kwefiriji mufiriji.
(4) Kudzivirirwa Pamusoro
Munguva yekugadzira, pazvikamu zvinokwenywa zviri nyore zvakaita sefiriji negirazi, kufukidza netepi yefirimu yepolyester kunogona kudzivirira kusakara panguva yekugadzirisa kana kubata, uye tepi inogona kubvarurwa mushure mekuiswa.
Hunhu hwayo hwekusapisa zvakanyanya (hwakakodzera nzvimbo inodziya zvakanyanya mukati mefiriji) uye kusapisa hunyoro (kuti ikwanise kurarama nehutsi hwemvura hwakapfava mukati mefiriji) zvinoita kuti ikwanise kushanda zvakanaka, zvichiita kuti firiji igare yakachengeteka uye kwenguva refu.
Ndeapi marudzi akajairika?
(1) PET10
Inoshandisa firimu repolyester rine ukobvu hwepasi hwe0.036mm, ukobvu hwese hwe0.056mm, simba rekubvisa ganda re ≥ 1.5N/25MM, uye tembiricha yekushanda ye – 10℃ ~ 80℃.
(2) PETB
PETB inoshandisa guruu rerabha, rine simba rekusvuuka re ≥ 3.5N/25MM. Tembiricha yayo yebasa yakafanana neyePET10, ine misiyano midiki.
(3) PET500L
Ukobvu hwePET500L hwehwaro i0.033mm. Zvikamu zvayo zvikuru ipolyester film nemafuta-based glue. Simba reganda i ≥ 4N/25MM, uye tembiricha inodiwa i 0℃ ~ + 40℃.
Ndezvipi zviitiko zvekushandisa?
Pamidziyo yemagetsi yakajairika, kusanganisira mafiriji madiki, makabati madiki ezvinwiwa, makabati eice cream, makabati emakeke, uye makabati etafura - girazi repamusoro - mhepo yemusuwo - maketeni, zvikamu zvemukati zvese zvinoshandisa tepi yepolyester film. Pakushandisa, zvinodikanwa kushanda zvakanyatsoenderana nemirairo.
Mutengo wetepi yefirimu yepolyester ndiyo yakaderera. Inogona kutengwa yakawanda kubva kumugadziri. Zvakakosha kutarisa kana inokodzera uye kana ine rezinesi rekuchengetedza kugadzirwa kwayo. Ehe, kusarudza ine zita rechiratidzo kwaizova nani.
