Kumvetsetsa Zida Zosiyanasiyana za Mafilimu Oteteza Paint Paint

Filimu yoteteza utotondi zopanda colorless ndi mandala, sizimakhudza kukongola kwa mtundu galimoto galimoto, ndipo ali mkulu kuuma ndi kusinthasintha zabwino, ngakhale ntchito makiyi ndi zinthu zina zovuta padziko kukangana mobwerezabwereza sadzasiya kuda.

Lili ndi ntchito yolimbana ndi kuwala kwa ultraviolet ndikuletsa zitsulo zachitsulo kuti zisachite dzimbiri.

Pewani mvula ndi dzimbiri la asidi, tetezani mbali zonse za galimoto kuti zisasevuke ndi kukanda, ndipo pentini penti kuti isachite dzimbiri ndi kukalamba yachikasu. Tsopano pamsika kuti achite mbiri yabwino, opanga mafilimu amagalimoto ali ndi maziko aku US, filimu ya chinjoka, 3M, Weigu, ndi zina zotero, zotsika mtengo, zotsika mtengo.Magulu a PPF, mtundu wakale ndi wodalirika.

Ndiye, kodi filimu yoteteza thupi imatani kuti iteteze thupi? Kodi zinthu zake ndi zotani?

ANGATHE

Polyurethane, kapena polyurethane (Polyurethane), kapena PU, ndi zinthu zomwe zikubwera polima zomwe zimadziwika kuti "pulasitiki wamkulu wachisanu." Mbadwo woyamba wa filimu yoteteza utoto umapangidwa ndi zinthu za PU. Poyamba idagwiritsidwa ntchito m'gulu lankhondo kuteteza ndege, zombo, ndi zina zambiri. Zida za PU, ngakhale kuti zimakhala ndi zomveka, zolimba zamphamvu, zofewa, ndi mphamvu zowonongeka bwino, chifukwa cha kusagwirizana kwa nyengo, mphamvu yofooka yolimbana ndi dzimbiri zamchere, komanso chikasu chosavuta, chinachotsedwa mwamsanga pamsika.

Zithunzi za PVC

Ngakhale kuti PU yachotsedwa pamsika, chidwi cha anthu pa utoto wagalimoto sichinathetse PU, ndipo filimu yachiwiri yoteteza utoto, PVC, yakhalapo. PVC ndi amodzi mwa omwe amapanga zinthu zamapulasitiki padziko lonse lapansi; ndi dzina lonse la polyvinyl chloride, chigawo chachikulu cha polyvinyl chloride. Zida za PVC ndizovuta kwambiri, zimakhala ndi mphamvu zotsutsa, ndipo zimakhala zotsika mtengo. Komabe, chifukwa cha kutambasula ndi kusinthasintha kwa ofooka, sitingathe kuzindikira zotsatira za m'mphepete mwa njira yeniyeni yokwezera. Nthawi yomweyo, moyo wautumiki wa zinthu za PVC ndi waufupi; pakapita nthawi, padzakhala chikasu, kudetsa, kusweka, ndi zina zotero. Ngakhale kuti PVC ili ndi mlingo wina wa kutentha kwa moto, kutentha kwake kumakhala kosauka, ndipo kutentha kwakukulu kumayambitsa kuwonongeka, motero kumasula hydrogen chloride ndi mpweya wina woopsa, kupangitsa thupi la munthu ndi chilengedwe kukhala chovulaza kwambiri.

TPU

Anthu chitetezo cha utoto choyambirira galimoto, komanso kulabadira chitetezo cha chilengedwe; filimu yoteteza utoto wachitatu, TPU, idabadwa; TPU imadziwikanso kuti thermoplastic polyurethane, dzina lonse la ThermoplasticPolyrethanes. TPU imakonzedwa kutengera PU kuti ipereke kukana kuzizira bwino, kukana dothi, kusinthasintha, komanso kudzikumbukira. Nthawi yomweyo, TPU ndi chinthu chokhwima, chokonda zachilengedwe chomwe sichiipitsa chilengedwe. Komabe, mutakhala ndi ubwino wambiri, mtengo wake udzakhala wapamwamba kusiyana ndi mtengo wa mibadwo iwiri yoyambirira ya filimu yoteteza utoto.TPHTPH ndi mankhwala omwe sanatulukepo m'zaka ziwiri zapitazi. Zomwe zimatchedwa TPH zitha kufananizidwa ndi TPU, zomwe zimakhalabe PVC, zomwe zimangowonjezera pulasitiki, kotero kuti zinthu za PVC zimakhala zofewa komanso zomangamanga zimakhala zowongoka kuposa za PVC. Komabe, mapulasitiki amakhalansopo kuti mankhwalawa ayambe kuphulika, ndipo patapita nthawi yaitali, padzakhala kusweka. Kuphatikiza apo, zomatira za zinthu za TPH zimagwa mwachangu, ndikupanga zomatira kapena zomatira zotsalira pamtunda wa utoto, zomwe zimakhudza ntchito yomanga.
