Makasitomala ambiri anena kuti TPU yowonekera bwino imakhala yowonekera bwino ikapangidwa koyamba, n’chifukwa chiyani imakhala yosawonekera bwino pakatha tsiku limodzi ndipo imawoneka ngati mpunga patatha masiku angapo? Ndipotu, TPU ili ndi vuto lachilengedwe, lomwe ndi lakuti pang’onopang’ono imasanduka yachikasu pakapita nthawi. TPU imayamwa chinyezi kuchokera mumlengalenga ndikukhala yoyera, kapena izi zimachitika chifukwa cha kusamuka kwa zowonjezera zomwe zimawonjezedwa panthawi yokonza. Chifukwa chachikulu ndichakuti mafutawo ndi osawonekera bwino, ndipo chikasu ndi chizindikiro cha TPU.
TPU ndi utomoni wachikasu, ndipo MDI mu ISO imasintha kukhala yachikasu ikawotchedwa ndi UV, zomwe zikusonyeza kuti chikasu cha TPU ndi chizindikiro. Chifukwa chake, tiyenera kuchedwetsa nthawi yachikasu ya TPU. Ndiye tingapewe bwanji TPU kuti isasinthe?
Njira 1: Pewani
1. Sankhani kupanga zinthu zakuda, zachikasu, kapena zakuda poyamba popanga zinthu zatsopano. Ngakhale zinthu za TPU izi zitasanduka zachikasu, mawonekedwe ake sangawonekere, kotero mwachibadwa palibe vuto la chikasu.
2. Pewani kukhudzana ndi dzuwa mwachindunji ndi PU. Malo osungira PU ayenera kukhala ozizira komanso opumira mpweya, ndipo PU ikhoza kukulungidwa m'matumba apulasitiki ndikuyikidwa pamalo opanda kuwala kwa dzuwa.
3. Pewani kuipitsidwa mukamagwiritsa ntchito pamanja. Zinthu zambiri za PU zimaipitsidwa panthawi yosankha kapena kupulumutsa, zomwe zimapangitsa kuti zikhale zachikasu monga thukuta la anthu ndi zinthu zosungunulira zachilengedwe. Chifukwa chake, zinthu za PU ziyenera kuyang'anitsitsa kwambiri ukhondo wa thupi lokhudzana ndi thupi ndikuchepetsa njira yosankha momwe zingathere.
Njira 2: Kuwonjezera zosakaniza
1. Sankhani mwachindunji zipangizo za TPU zomwe zikugwirizana ndi zofunikira za kukana kwa UV.
2. Onjezani mankhwala oletsa chikasu. Kuti muwonjezere mphamvu ya PU yoletsa chikasu, nthawi zambiri pamafunika kuwonjezera mankhwala apadera oletsa chikasu ku zinthu zopangira. Komabe, mankhwala oletsa chikasu ndi okwera mtengo, ndipo tiyeneranso kuganizira za ubwino wawo wazachuma tikamawagwiritsa ntchito. Mwachitsanzo, thupi lathu lakuda silikhudzidwa ndi chikasu, kotero tingagwiritse ntchito zinthu zopangira zotsika mtengo zosaletsa chikasu popanda mankhwala oletsa chikasu. Popeza mankhwala oletsa chikasu ndi chinthu chowonjezera chomwe chimawonjezeredwa ku gawo A, timafunika kusakaniza tikasakaniza kuti tipeze kufalikira kofanana komanso zotsatira za chikasu, apo ayi chikasu chapafupi chingachitike.
3. Kupopera utoto wachikasu wokana kupopera. Nthawi zambiri pamakhala mitundu iwiri ya kupopera utoto, umodzi umakhala wopopera utoto ndi wina wokana kupopera utoto. Kupopera utoto wachikasu wokana kupopera utoto kumapanga gawo loteteza pamwamba pa zinthu zomalizidwa ndi PU, kupewa kuipitsa ndi chikasu chomwe chimachitika chifukwa cha kukhudzana kwa khungu la PU ndi mlengalenga. Mtundu uwu umagwiritsidwa ntchito kwambiri pakadali pano.
Njira 3: Kusintha zinthu
TPU yambiri ndi TPU yonunkhira bwino, yomwe ili ndi mphete za benzene ndipo imatha kuyamwa mosavuta kuwala kwa ultraviolet ndikuyambitsa chikasu. Ichi ndiye chifukwa chachikulu cha zinthu za TPU kukhala zachikasu. Chifukwa chake, anthu omwe ali mumakampaniwa amaona kuti TPU imakhala ndi anti-ultraviolet, anti-yellowing, anti-aging komanso anti-ultraviolet. Opanga TPU ambiri apanga TPU yatsopano ya aliphatic kuti athetse vutoli. Mamolekyu a Aliphatic TPU alibe mphete za benzene ndipo amakhala ndi photositability yabwino, samasintha kukhala achikasu.
Zachidziwikire, TPU ya aliphatic ilinso ndi zovuta zake masiku ano:
1. Kuuma kwake ndi kopapatiza, nthawi zambiri pakati pa 80A-95a
2. Njira yogwiritsira ntchito ndi yosamala kwambiri komanso yosavuta kugwiritsa ntchito
3. Kusowa kwa kuwonekera bwino, kungapangitse kuwonekera bwino kwa 1-2mm yokha. Chogulitsa chokhuthala chikuwoneka ngati chifunga pang'ono
