Zipangizo za nsalu zapamwamba za TPU mndandanda wa TPU

Polyurethane ya Thermoplastic (TPU)ndi nsalu yogwira ntchito bwino kwambiri yomwe ingasinthe momwe nsalu zimagwiritsidwira ntchito kuyambira ulusi wolukidwa, nsalu zosalowa madzi, ndi nsalu zosalukidwa mpaka chikopa chopangidwa. TPU yogwira ntchito zambiri imakhala yolimba, yokhala ndi kukhudza komasuka, kulimba kwambiri, komanso mawonekedwe ndi kuuma kosiyanasiyana.

Choyamba, zinthu zathu zamtundu wa TPU zimakhala ndi kusinthasintha kwakukulu, kulimba, komanso kusakalamba, zomwe zikutanthauza kuti nsalu zitha kugwiritsidwanso ntchito popanda kusintha. Kukana mafuta, kukana mankhwala, komanso kukana UV zimapangitsanso TPU kukhala chinthu chachilengedwe chomwe chimasankhidwa kugwiritsidwa ntchito panja.

Kuphatikiza apo, chifukwa cha kugwirizana kwa zinthu, kupuma bwino, komanso kuyamwa chinyezi kwa nsaluyo, ovala amakonda kusankha nsalu zopepuka za polyurethane (PU) zokhala ndi kukhudza bwino komanso kouma.

Thanzi la zinthu lingathenso kuwonjezeredwa mpaka kufika podziwa kuti TPU ikhoza kubwezeretsedwanso kwathunthu, ndipo zinthuzo zimayambira pa zofewa kwambiri mpaka zolimba kwambiri. Poyerekeza ndi njira zina, iyi ndi njira yokhazikika ya chinthu chimodzi. Ilinso ndi zinthu zovomerezeka zotsika volitable organic compound (VOC), zomwe zingachepetse mpweya woipa.

TPU ikhoza kusinthidwa kuti ikhale ndi zinthu zinazake monga kuletsa madzi kulowa kapena kukana mankhwala m'mafakitale. Mwachidule, zinthuzi zitha kusinthidwa pogwiritsa ntchito njira zinazake zokonzera, kuyambira kuluka ulusi mpaka kupanga, kutulutsa, ndi kusindikiza kwa 3D, potero kupangitsa kuti mapangidwe ndi kupanga zikhale zosavuta. Nazi njira zingapo zomwe TPU imagwirira ntchito bwino.

Ntchito: Yogwira ntchito zambiri, yogwira ntchito kwambiriUlusi wa TPU
TPU ikhoza kupangidwa kukhala ulusi wa ulusi umodzi kapena iwiri, ndipo njira zamankhwala zimagwiritsidwa ntchito pafupifupi nthawi zonse (96%). Kupaka utoto wa anhydrous kungachepetse kuwononga chilengedwe kwa njira zopangira. Mosiyana ndi zimenezi, pamene kusungunuka kwa madzi, njirazi nthawi zambiri sizigwiritsidwa ntchito, kotero njirazi zimakhala ndi mpweya wochepa wa VOC kapena palibe. Kuphatikiza apo, kusungunuka kwa madzi kumakhala ndi khungu lofewa kwambiri.

Kugwiritsa Ntchito: Nsalu ya TPU yosalowa madzi, yogwiritsidwa ntchito popangira zophimba magalimoto, matumba a njinga, ndi chikopa chopangidwa
TPU yosalowa madzi komanso yosadetsedwa ndi madontho. Pogwiritsidwa ntchito ndi nthawi yake yayitali, ukadaulo wa TPU ndi chisankho chabwino kwambiri pakugwiritsa ntchito zinthu zolemera monga nsalu zosalowa madzi zamagalimoto, matumba a njinga, ndi chikopa chopangidwa. Phindu limodzi lofunika ndilakuti polyurethane ya thermoplastic ndi yosavuta kuigwiritsanso ntchito kuposa nsalu zambiri zosalowa madzi zomwe zilipo.

Palibe mankhwala omwe amagwiritsidwa ntchito mu njira zotenthetsera monga kupukuta kapena kutulutsa kwa T-die kuti zitsimikizire kuchepetsa kapena kuchotsa kwathunthu ma VOC. Nthawi yomweyo, palibe chifukwa chomwa madzi kuti muchotse mankhwala ochulukirapo, omwe ndi gawo lodziwika bwino la mankhwala.

Ntchito: Chikopa chopangidwa cha TPU cholimba komanso chobwezerezedwanso
Maonekedwe ndi kamvekedwe ka chikopa chopangidwa n'kovuta kusiyanitsa ndi chikopa chachilengedwe, ndipo nthawi yomweyo, chinthucho chili ndi mitundu ndi mawonekedwe osatha, komanso kukana mafuta a TPU, kukana mafuta, komanso kukana kuvala. Chifukwa cha kusakhalapo kwa zinthu zopangira zopangidwa ndi nyama, chikopa chopangidwa ndi TPU ndi choyenera kwambiri kwa anthu osadya nyama. Pamapeto pa gawo logwiritsidwa ntchito, chikopa chopangidwa ndi PU chikhoza kubwezeretsedwanso ndi makina.

Ntchito: Nsalu yosalukidwa
Chinthu chapadera chomwe chimagulitsidwa ndi nsalu ya TPU yosalukidwa ndi kukhudza kwake kosavuta komanso kofewa, komanso kuthekera kopindika, kutambasula, ndi kusinthasintha mobwerezabwereza pa kutentha kwakukulu popanda kusweka.

Ndi yoyenera kwambiri pa zovala zamasewera ndi zovala wamba, komwe ulusi wotambalala ungaphatikizidwe mu kapangidwe ka maukonde opumira bwino, zomwe zimapangitsa kuti mpweya ulowe mosavuta komanso kuti thukuta lituluke mosavuta.

Chokumbukira mawonekedwe chingapangidwenso kukhala nsalu ya TPU polyester yosalukidwa, yomwe kutentha kwake kochepa kumatanthauza kuti imatha kutenthedwa pa nsalu zina. Zipangizo zosiyanasiyana zobwezerezedwanso, zozikidwa pang'ono pa bio, komanso zosasinthika zingagwiritsidwe ntchito pa nsalu zosalukidwa.
