Mapepala apulasitiki a PET ndi omveka bwino, olimba, ndipo amagwiritsidwa ntchito kwambiri popaka, kuwonetsa, ndi makina. Kudziwa mtengo wake kumathandiza kupewa kulipira mopitirira muyeso kapena kusankha mtundu wolakwika.

Mu positi iyi, muphunzira zomwe zimakhudza mitengo ya mapepala a PET, mitundu yofunika, komanso momwe ogulitsa mapepala a ziweto monga HSQY angathandizire.

Kodi pepala la pulasitiki la PET limapangidwa ndi chiyani?

Pepala la pulasitiki la PET limachokera ku chinthu chotchedwa polyethylene terephthalate. Ndi chimodzi mwa zinthu zodziwika bwino za thermoplastic zomwe timaziona tsiku lililonse. Mungazipeze m'mabotolo, m'mabotolo, komanso m'zovala zikagwiritsidwa ntchito ngati polyester. Koma likapangidwa kukhala pepala, limakhala chinthu chowoneka bwino komanso cholimba choyenera kulongedza ndi kugwiritsidwa ntchito m'mafakitale.

Mwachilengedwe, pepala la PET ndi lopepuka koma lolimba. Kuchuluka kwake ndi pafupifupi magalamu 1.38 pa sentimita imodzi, zomwe zimathandiza kuti likhale lolimba popanda kulemera. Pa kutentha, limagwira ntchito kutentha mpaka madigiri 170 Celsius, ngakhale kuti nthawi zambiri limagwiritsidwa ntchito tsiku ndi tsiku. Pamakina, ndi lolimba komanso losasweka, ndichifukwa chake mafakitale ambiri amalisankha m'malo mwa galasi kapena acrylic.

Pepala la PET limaonekeranso bwino momwe limagwirira ntchito likapanikizika. Lili ndi mphamvu yokoka kwambiri, kotero siling'ambika mosavuta pokonza kapena kunyamula. Izi zimapangitsa kuti likhale lothandiza pazinthu monga kupanga mathireyi kapena kusindikiza zophimba zowonekera bwino. Ngakhale likatentha, limakhala lolimba mokwanira kuti lipangidwe mu thermoforming, zomwe zimapangitsa anthu kulipanga kukhala ma paketi, zoyikamo, kapena mabokosi okongoletsera popanda vuto lalikulu.

Chifukwa cha zinthu zimenezi, pepala la PET limawonekera paliponse. Kupaka ndi ntchito yaikulu, makamaka pa chakudya ndi zamagetsi. Ndikofala m'mabokosi owonekera bwino a mawindo, makatoni apulasitiki, ndi mapaketi a ma blister. Thermoforming imagwiritsa ntchito kupanga zinthu monga mathireyi osungiramo zinthu kapena zivindikiro. Posindikiza, imapereka zotsatira zoyera komanso zomveka bwino. Mudzaziwonanso m'mapanelo a magalimoto ndi zizindikiro zotsatsa, komwe mphamvu ndi mawonekedwe zonse ziwiri ndizofunikira.

Kusinthasintha kumeneku ndiko komwe kumapangitsa pepala la pulasitiki la PET kukhala lokondedwa ndi ogulitsa mapepala a ziweto. Amadalira kuti litumikire misika yambiri—kuyambira ogwiritsa ntchito mafakitale mpaka makampani ogulitsa omwe amafunika kulongedza bwino komanso molunjika.

Kodi Mtengo wa Pepala la Pulasitiki la PET Umawerengedwa Bwanji?
