Magawo ogwiritsira ntchito ndi zabwino za kudula kwa laser mu filimu ya PET

Filimu ya PET, yomwe imadziwikanso kuti filimu ya polyester yosatentha kwambiri, imakhala ndi kukana kutentha kwambiri, kukana kuzizira, kukana mafuta komanso kukana mankhwala. Malinga ndi ntchito yake, imatha kugawidwa m'magulu awiri: filimu yowala kwambiri ya PET, filimu yophimba mankhwala, filimu yoteteza kutentha ya PET, filimu yotseka kutentha ya PET, filimu yochepetsa kutentha ya PET, filimu ya PET yopangidwa ndi aluminiyamu, ndi zina zotero. Ili ndi makhalidwe abwino kwambiri, makhalidwe a mankhwala komanso kukhazikika kwa mawonekedwe, kuwonekera bwino komanso kubwezeretsanso, ndipo ingagwiritsidwe ntchito kwambiri pojambula maginito, zinthu zowunikira kuwala, zamagetsi, kutchinjiriza magetsi, mafilimu amafakitale, zokongoletsera ma CD ndi zina. Imatha kupanga filimu yoteteza ya LCD pafoni yam'manja, filimu yoteteza ya LCD TV, mabatani a foni yam'manja, ndi zina zotero.

Mafilimu a PET omwe amagwiritsidwa ntchito nthawi zambiri ndi awa: makampani opanga ma optoelectronic, makampani opanga zamagetsi, makampani opanga mawaya ndi zingwe, makampani opanga zida zamagetsi, makampani osindikizira, makampani opanga pulasitiki, ndi zina zotero. Ponena za ubwino wachuma, monga kuwonekera bwino, chifunga chochepa komanso kuwala kwambiri. Amagwiritsidwa ntchito makamaka pazinthu zapamwamba zopangidwa ndi aluminiyamu. Pambuyo popaka aluminiyamu, imakhala ngati galasi ndipo ili ndi zotsatira zabwino zokongoletsa; ingagwiritsidwenso ntchito pa filimu yotsutsana ndi zinthu zabodza ya laser, ndi zina zotero. Mphamvu yamsika ya filimu ya BOPET yowala kwambiri ndi yayikulu, mtengo wowonjezera ndi wapamwamba, ndipo phindu lazachuma ndi lodziwikiratu.
Ma laser omwe amagwiritsidwa ntchito podula filimu ya PET ndi ma laser a nanosecond solid-state ultraviolet omwe ali ndi kutalika kwa 355nm. Poyerekeza ndi kuwala kobiriwira kwa 1064nm ndi 532nm, 355nm ultraviolet ili ndi mphamvu yayikulu ya photon imodzi, kuchuluka kwa kuyamwa kwa zinthu, kutentha kochepa, ndipo imatha kukwaniritsa kulondola kwakukulu kwa kukonza. Mphepete mwachitsulo ndi yosalala komanso yoyera, ndipo palibe ma burrs kapena m'mphepete pambuyo pokulitsa.
Ubwino wa kudula kwa laser umaonekera makamaka mu:
1. Kudula kolondola kwambiri, msoko wopapatiza wodula, khalidwe labwino, kukonza kozizira, malo ang'onoang'ono okhudzidwa ndi kutentha, komanso malo odulira osalala;
2. Kuthamanga mwachangu, kugwira ntchito bwino kwambiri, komanso kugwira ntchito bwino kwa kupanga;
3. Kugwiritsa ntchito benchi yogwirira ntchito yolumikizana bwino, kukonza njira yogwirira ntchito yokha/yogwiritsira ntchito pamanja, komanso kukonza bwino;
4. Ubwino wa denga lapamwamba, limatha kupeza chizindikiro chabwino kwambiri;
5. Ndi njira yosakhudzana ndi zinthu, yopanda kusintha kwa zinthu, tchipisi topangira zinthu, kuipitsa mafuta, phokoso ndi mavuto ena, ndipo ndi njira yobiriwira komanso yosamalira chilengedwe;
6. Kutha kudula bwino, kumatha kudula chilichonse;
7. Chimango chachitetezo chotsekedwa bwino kuti chiteteze chitetezo cha ogwiritsa ntchito;
8. Makinawa ndi osavuta kugwiritsa ntchito, alibe zinthu zogwiritsidwa ntchito, komanso amagwiritsa ntchito mphamvu zochepa.
