TPU Mlandu Wafoni: Ubwino ndi Kuipa

Ogwiritsa ntchito ambiri adzakonzekeretsa mafoni awo ndi "chovala" (chovala chafoni), chomwe chingachepetse kwambiri kuwonongeka ngati kutayidwa mwangozi. Palinso mitundu yambiri ya zida zama foni awa, monga silikoni, pulasitiki, utomoni, TPU, Ndi zina zotero.

Kodi TPU foni yapangidwa ndi chiyani?

Thermoplastic polyurethane elastomer (TPU), yomwe imadziwikanso kuti mphira wa polyurethane, ndi mtundu wazinthu zotanuka polima zomwe zimakhala ndi magulu ambiri a amino acid ester (-NHCOO-) mu unyolo wa maselo. Ndizinthu zapulasitiki zomwe zimatha kufewetsa mobwerezabwereza kapena kusintha pa kutentha kwina, pamene zimatha kusunga mawonekedwe ake ndikugwira ntchito yothandizira ndi kuteteza kutentha kwapakati. Amagwiritsidwa ntchito kwambiri pazinthu za nsapato, zomatira, mapaipi, mafilimu, zikopa zopangira, mawaya ndi zingwe, ma dashboards, milandu ya foni, mabandeji azachipatala, ndi zina zambiri.

Ndi kuwonjezera kwa TPU ntchito zakuthupi, zida zamasewera ndi nsapato zimakonda kwambiri TPU mankhwala, makamaka UV zosagwira ndi mandala zipangizo. Chifukwa chake, TPU zida zili ndi kuthekera kwakukulu kwachitukuko m'munda wa zinthu zamasewera ndi nsapato zamasewera.

Is TPU foni yolimba kapena yofewa?

TPU foni yam'manja ndi yofewa, koma yolimba pang'ono kuposa silikoni, ndipo imakhala yolimba kwambiri.

TPU ndi chipika copolymer, ndipo kuchuluka kwa zigawo zolimba ndi zofewa zimatsimikizira ntchito ya TPU. Gawo lolimba limakhala ndi mphamvu yapadera pa modulus, kuuma, ndi kugwetsa mphamvu, pamene gawo lofewa limakhudza makamaka kusungunuka ndi kutentha kochepa kwa mankhwala. TPU ali ndi kusinthasintha kwabwino kwambiri komanso kulimba mtima, ndipo amatha kuchoka ku zofewa kwambiri mpaka zolimba kwambiri, kuchokera ku kusinthasintha kwabwino mpaka kulimba kwambiri, kapena kuchokera ku mitundu ya hydrophilic yomwe imatha kuyamwa madzi kupita ku mitundu ya hydrophobic yomwe imathamangitsa madzi. Imasunga kusungunuka kwakukulu mkati mwa kuuma kosiyanasiyana (Shore A10-D75), ndipo imakhala ndi mphamvu yonyamula katundu kuposa ma elastomer ena pa kuuma komweko.

nditero TPU foni yam'manja imakhala yachikasu?

Inde, mukagula foni yowoneka bwino kapena yopepuka ngati yoyera, imatha kukhala yachikasu pakadutsa miyezi itatu kapena inayi. Komabe, ngati amangotembenukira chikasu ndipo sakhala chifunga kapena zomata, zikutanthauza kuti khalidwe la TPU foni yomwe mudagula ikadali yabwino. Kutentha kwa TPU foni mlandu okhudzana ndi kusankha zipangizo. Ntchito yoletsa kukalamba ya ma saturated hydrocarbons ndiyabwino kuposa yamafuta onunkhira. Kuphatikiza apo, kuwonjezera ma antioxidants ndi zowonjezera zolimbana ndi UV zimatha kusintha vuto la chikasu.

Ubwino ndi kuipa kwa TPU foni ya foni

Phindu lalikulu kwambiri la TPU zakuthupi ndi kusinthasintha kwake kwabwino, komwe kumatha kupunduka mosavuta. Chifukwa chake, ma foni opangidwa ndi nkhaniyi ali ndi magwiridwe antchito abwino, amatha kupewa kugwa, ndipo ndi osavuta kuyiyika ndikuchotsa. Kuphatikiza apo, TPU zakuthupi zitha kugwiritsa ntchito ukadaulo wa micro-matte kuteteza bwino zala ndikuwonetsetsa ukhondo wa foni. TPU elastomer ndi zinthu pakati mphira ndi pulasitiki. Lili ndi ntchito za kukana mafuta, kukana madzi, komanso kukana mildew. TPU Zogulitsa zimakhala ndi mphamvu yabwino yonyamula katundu, kukana kukhudzidwa, komanso kugwira ntchito modzidzimutsa. TPU ndi gulu pulasitiki, ndipo mankhwala amapangidwa ndi jekeseni akamaumba ndondomeko. Akatenthetsa ndi kusungunula njere za pulasitiki za mpunga, amabayidwa mu nkhungu ya pulasitiki ndi mbiya kuti apange mankhwala.

Ubwino: kukana kwambiri kuvala, mphamvu zambiri, kukana kuzizira kwambiri, kukana mafuta, kukana madzi, kukana mildew, komanso kusinthasintha kwabwino.

Zoipa: zosavuta kupunduka ndikutembenukira chikasu.
