Ndi maubwino ati a filimu yamasewera?

Kanema kanema(I.e. Polyethylene Terephthalate filimu) ndi zinthu zolimbitsa thupi kwambiri. Ndi magwiridwe ake abwino kwambiri, amakhala osewera ozungulira "m'minda, amagwiritsa ntchito zamagetsi, ndi zomanga. Mphamvu zake zapadera sizingakwaniritse zofunikira zoyambira ntchito, komanso zimakulitsa mosalekeza ntchito yake pantchito yaukadaulo, ndikukhala ndi zinthu zofunikira m'mafakitale amakono.

Katundu wabwino kwambiri, mphamvu zonse ndi kulimba

Mphamvu ya filimu ya petfile ndi nthawi 3-5 nthawi ya filimu ya polyethylenene. Imatha kupirira mphamvu zazikulu zosavuta. M'munda wamasamba, umatha kukana kudzitukuka komanso kupembekana ndi kunyamula. Nthawi yomweyo, imakhala ndi kulimba kwambiri, ndi gawo limodzi ndi 100% -300%. Sizovuta kusweka pambuyo polunjika kapena kuwerama. Ndizoyenera makamaka pamawonekedwe omwe amafunikira kuwomba mobwerezabwereza, monga momwe mafilimu amagwiritsira ntchito buku limakwera ndi zingwe zokutira pazitsulo zamagetsi. "Mphamvu yolimba koma yosasunthika koma yosasunthika imathandizira kuti ikhale bwino kwambiri pakusintha zinthu za cellophane ndi filimu ya PVC.

Kukhazikika kwamphamvu kwa mankhwala, kusinthika ku malo ovuta

Filimu filimuyi imakhala ndi mankhwala osokoneza bongo azachilengedwe, kukana mwamphamvu kwa asidi, alkalis, okhazikika, etc. Imakhala ndi madzi oletsa kutentha ndipo amatha kukhalabe ndi magwiridwe antchito a -70 ℃ mpaka 150 ℃. Itha kugwiritsidwa ntchito modekha pazomera za kutentha monga kuthirira kwa chakudya cha chakudya. Kuphatikiza apo, kanema wa pet sikophweka kuyamwa madzi, ndi kuyamwa kwamadzi kwa 0,1% yokha. Itha kukhalabe ndi bata yachilengedwe kwambiri ndikupewa makwinya, kuwonongeka ndi mavuto ena, omwe ndikofunikira kuti akwaniritse zigawo zamagetsi.

Kuchita bwino kwambiri kwamisonkhano, kukwaniritsa zofunika kwambiri

Kuwala kowalaKanema kanemaimatha kufikira zoposa 90%, ndipo tsitsi limakhala lochepera 2%. Itha kuwonetsa bwino maonekedwe a zinthu zoyikidwa ndipo zimagwiritsidwa ntchito kwambiri pazakudya za pawindo ndi mphatso. Filimuyanema yojambulidwa bwino imathanso ndi ntchito zabwino kwambiri, monga filimu yowala imatha kuwonjezera zowoneka bwino za LCD, ndipo filimu yolunjika imagawidwa mopepuka zida zowonetsera monga mafoni am'manja ndi ma TV. Poyerekeza ndi galasi, kanema wa pet amalemera 1/5 yokha yagalasi yomweyo ndipo sikophweka kusiya. Ili ndi zabwino zambiri pazochitika zomwe zimafuna zopepuka ndikulimbana (monga kuwonetsa magalimoto).

Kusintha kwamphamvu komanso malo akulu opangira ntchito

Kanema wa pet amatha kusinthidwa kudzera mu njira zosiyanasiyana kuti mupindule ndi zinthu zosiyanasiyana. Mukakuta, tepi yomata ya pet itha kupezeka, yomwe imagwiritsidwa ntchito kwambiri kukonza zinthu zamagetsi; Kanema wa petfinid wopangidwa atatha kupatuka kwambiri ndi mawonekedwe otetezedwa komanso osachiritsa, ndipo nthawi zambiri amagwiritsidwa ntchito ponyamula chakudya monga khofi ndi khofi yomwe imafunikira kuti ichotsedwe kuwunika; Phunziro la zoweta ndi moto wowotchera zowonjezeredwa amatha kukwaniritsa zofunikira zamoto pomanga ndi minda yamagalimoto. Kuphatikiza apo, filimu ya zinyama ndizosavuta kusindikiza, zimapangitsa kuti inki yolimba ikhale yosindikiza, ndipo imagwira ntchito bwino m'magawo a zilembo ndi zokongoletsera.

Kusamala pakati pa kutetezedwa kwa chilengedwe ndi ntchito zachuma, mogwirizana ndi chitukuko chokhazikika

Filimu filimuyi ndi zinthu zobwezerezedwanso, zomwe zitha kusinthidwa kukhala zopangidwa ndi ziweto zobwezerezedwa mwakuthupi kapena zamankhwala kuti muchepetse zinyalala. Poyerekeza ndi filimu ya PVC yopanda degrad Pankhani ya mtengo, filimu ya pet ili ndi phindu lalikulu ndi mtengo wake ndi wotsika kuposa wa ntchentche ya nylon, aluminium zojambulazo ndi zinthu zina zikagwiritsidwa ntchito m'matumba. Itha kuwongolera bwino ndalama za kampaniyo pomwe mukuwonetsetsa.

Kuchokera pazakudya zomata zam'manja, makanema osokoneza bongo azogulitsa zamagetsi, mpaka makanema ophulika mu gawo lomanga ndi makanema okongoletsera mu malonda agalimoto,Kanema kanemaZikupitilizabe kulowa maulumikizidwe osiyanasiyana okhala ndi maubwino ake okwanira a "mphamvu zazikulu, kuwonekera kwakukulu, kosavuta komanso kusintha kwakukulu". Ndi kukweza kwa ukadaulo wofuna ukadaulo wofuna kutetezedwa ndi ukadaulo wosinthira, filimu yamasewera idzawonetsa mtengo wake m'minda yayitali kwambiri ndikukhala mtundu wa zinthu zobiriwira komanso zolimbitsa thupi.
