Makasitomala ambiri anena kuti TPU yowonekera kwambiri imawonekera ikapangidwa koyamba, chifukwa chiyani imakhala yosamveka pakadutsa tsiku ndikuwoneka ngati mtundu wa mpunga patatha masiku angapo? M'malo mwake, TPU ili ndi vuto lachilengedwe, lomwe limasanduka lachikasu pakapita nthawi. TPU imatenga chinyezi kuchokera mumlengalenga ndikusandulika kukhala oyera, kapena izi zimachitika chifukwa cha kusamuka kwa zowonjezera zomwe zimawonjezeredwa pakukonza. Chifukwa chachikulu ndi chakuti mafuta ndi opaque, ndi chikasu ndi khalidwe la TPU.
TPU ndi utomoni wachikasu, ndipo MDI mu ISO imasanduka yachikasu pansi pa kuwala kwa UV, kusonyeza kuti TPU chikasu ndi katundu. Chifukwa chake, tiyenera kuchedwetsa nthawi yachikasu ya TPU. Ndiye mungaletse bwanji TPU kuti ikhale yachikasu?
Njira 1: Pewani
1. Sankhani kupanga zinthu zakuda, zachikasu, kapena zakuda poyambira kupanga zatsopano. Ngakhale zinthu za TPU izi zitakhala zachikasu, mawonekedwe awo sangawoneke, kotero mwachilengedwe palibe vuto lachikasu.
2. Pewani kukhudzana ndi dzuwa mwachindunji ku PU. Malo osungiramo PU ayenera kukhala ozizira komanso mpweya wabwino, ndipo PU ikhoza kukulungidwa m'matumba apulasitiki ndikuyika pamalo opanda dzuwa.
3. Pewani kuipitsidwa pa ntchito yamanja. Zinthu zambiri za PU zimayipitsidwa panthawi yakusanja kapena kupulumutsa, zomwe zimapangitsa kuti zikhale zachikasu monga thukuta la munthu ndi zosungunulira za organic. Chifukwa chake, zinthu za PU ziyenera kusamala kwambiri zaukhondo wamagulu olumikizana nawo ndikuchepetsa kusanja momwe mungathere.
Njira 2: Kuwonjezera zosakaniza
1. Mwachindunji sankhani zipangizo za TPU zomwe zimakwaniritsa zofunikira za UV.
2. Onjezani anti yellowing agents. Pofuna kupititsa patsogolo luso la anti yellowing la zinthu za PU, nthawi zambiri zimakhala zofunikira kuwonjezera zida zapadera za anti yellowing pazopangira. Komabe, anti yellowing agents ndi okwera mtengo, ndipo tiyenera kuganiziranso ubwino wawo pazachuma tikamagwiritsa ntchito. Mwachitsanzo, thupi lathu lakuda silikhudzidwa ndi chikasu, choncho titha kugwiritsa ntchito zipangizo zotsika mtengo zopanda anti yellowing popanda anti yellowing agents. Monga anti yellowing agents ndi zowonjezera zowonjezera zomwe zimawonjezeredwa ku chigawo A, timafunika kusonkhezera tikasakaniza kuti tikwaniritse kugawa kofanana ndi zotsatira zotsutsana ndi chikasu, apo ayi chikasu chaderalo chikhoza kuchitika.
3. Thirani utoto wachikasu wosamva. Nthawi zambiri pamakhala mitundu iwiri ya kupopera utoto, imodzi ndi kupopera mbewu mankhwalawa ndi nkhungu. Kupopera mbewu mankhwalawa kwa utoto wosamva zachikasu kumapanga gawo loteteza pamwamba pa zinthu zomalizidwa ndi PU, kupewa kuipitsidwa ndi chikasu chifukwa cholumikizana pakati pa khungu la PU ndi mlengalenga. Fomu iyi imagwiritsidwa ntchito kwambiri pakadali pano.
Njira 3: Kusintha zinthu
TPU yambiri ndi yonunkhira ya TPU, yomwe imakhala ndi mphete za benzene ndipo imatha kuyamwa mosavuta kuwala kwa ultraviolet ndikupangitsa chikasu. Ichi ndiye chifukwa chachikulu chopangira chikasu chazinthu za TPU. Chifukwa chake, anthu ogulitsa amawona anti ultraviolet, anti yellowing, anti-aging ndi anti ultraviolet ya TPU ngati lingaliro lomwelo. Opanga ambiri a TPU apanga TPU yatsopano ya aliphatic kuti athetse vutoli. Mamolekyu a Aliphatic TPU alibe mphete za benzene ndipo amakhala ndi photostability, osasinthika achikasu
Zachidziwikire, aliphatic TPU ilinso ndi zovuta zake masiku ano:
1. Mtundu wa kuuma ndi wopapatiza, nthawi zambiri pakati pa 80A-95a
2. The processing ndondomeko ndi mosamala kwambiri ndi yosavuta pokonza
3. Kupanda kuwonekera, kumatha kukwaniritsa kuwonekera kwa 1-2mm. Chopangidwa chokhuthala chikuwoneka ngati chifunga
