Izindawo Ezisetshenziswa Ngazo i-Film Blowing Machines: Ukuvula Izinguqulo Ze-Filimu PP Kuzo Zonke Izisindo
Indlela yokudonsa ifilimu isigaba somncedo indlela yokudonsa ifilimu ibalulekile kakhulu ekuphatheni kwamandla, lapho ifilimu ye-PP inombolo, inkabi, nokuthulaswa komthelelo okuncane kakhulu, kepha kungcono. Lezi zixhobo zikhiqa iziphiwo ezincane, ezibonakala kakhulu, ezifakelwa kuziphiwo ezincane—njengezipaki zezithelo, izipaki zezitshalo, nezibhodlela zezimpendulo zokucasha—lapho ubonakaliswa kweziphiwo kusiza abathengi ukuthenga. Futhi, zikhiqa iziphiwo ezinkulu, ezinobukhona obubi, ezifakelwa kuziphiwo ezikhulu: izibhodlela ezihleli (ukulungiselela ukungafuni kwezimali noma izintanga) nezibhodlela zokuthunyelwa (ukulungiselela ukugayaza ngokuhamba). Ngokulungiselela ubude bezifilimu nobude bezifilimu, le zixhobo zihlala zihambisana nezibhodlela eziphansi kakhulu nezibhodlela ezikhulu, zihambisana nezidingo ezahlukene zezinhlekeleli zokubhodlela.
U indlu yesithembu iqhathaniswa kakhulu ezimbeni zokuthutha kwamafilmu asebenzisa i-PP ukuze akhwe amafilmu ezigulwa enempilo. I-PP inemithombo yayo ye-UV nezama-aging (uma isetshenziswa ngezidingo) eyaziwayo, futhi kuyisisekelo esihle kumafilmu okubambela—lo mfundo usabela umlaba, uphazanya izimpande, kanye nokugcina umlaza, okunikeza ukukhula okuphakeme komthambo njengezithelo nezithelo. Lezi zimbi zakhelisa futhi amafilmu okufaka phansi kwegumbami, angathintwanga ngokuthi kusetyenziswe izidingo ezingaphazamisi umlaza (okubalulekile ekugcineni ukuthutha kwezibonakude) kanye namagugu athuthakala ukuqinisekisa ukusebenza kahle emasikweni afudume (isb. izindiza ezikhulu noma ubomi obujulile). Kumaqashi namaqashini amagugu, lezi zimbi ziqinisekisa ukulethana okuphelele kwamafilmu aphathekayo angcwalisa izidingo zokusebenza kahle kwegunya elisha.
Izimbi zokuthutha kwamafilmu asebenzisa i-PP zihlalisela futhi kwezigulwa zomphakathi nokuziphatha kwezimali zosizo . Kulomndeni, bakhokha izivumelwano ze-PP—ezisetshenziswa ukufaka izihlathi, i-aluminum profiles, nezinhlelo zezinhlelo (isb. izinkomba ze-circuit) ukuze kugodwe ukuthakatha, umoya, noma ukuchitha ngexesha lokugcina nokuthutha. Iziphazamiso zabo ezikhathazekayo (engazingeki zishiyela into) zibangela ukuthi zibe yinto ethandwayo kubakhokhi. Ngemisebenzi yethu yehluko, izimakhini zakhokha izivumelwano ezizinxibelelanayo ze-PP zezinto ezingashintshanga njengezihlathi, izicabha zokugquma, nezibhag thinta-thinta—ezinto ezenza imfundo eyiqiniso, enobukhona obupheleleyo. Zingakha futhi izivumelwano ezinezimo (isb. ezimbi noma ezineziphazamiso) zezinyathelo, njengekushumayela kwezinkunkuma noma izilabeli zesampula, zibanze ubunconyi bawo ngaphandle kwemisebenzi yazo.
