Zipangizo Zapamwamba za TPU za Mafilimu a TPU Otulutsa

Mafotokozedwe ndi Ntchito ZamakampaniZipangizo zopangira za TPUMafilimu amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha magwiridwe antchito awo abwino kwambiri. Izi ndi zomwe zafotokozedwa mwatsatanetsatane m'Chingerezi: 1. Chidziwitso Choyambira TPU ndi chidule cha thermoplastic polyurethane, chomwe chimadziwikanso kuti thermoplastic polyurethane elastomer. Zipangizo zopangira TPU za mafilimu nthawi zambiri zimapangidwa popolisha zinthu zitatu zazikulu: polyols, diisocyanates, ndi chain extenders. Polyols amapereka gawo lofewa la TPU, ndikulipatsa kusinthasintha ndi kusinthasintha. Diisocyanates amachita ndi polyols kuti apange gawo lolimba, zomwe zimathandiza kulimba kwa TPU. Zowonjezera unyolo zimagwiritsidwa ntchito kuwonjezera kulemera kwa mamolekyulu ndikukweza mawonekedwe a makina a TPU. 2. Njira Yopangira Mafilimu a TPU amapangidwa kuchokera ku zinthu za TPU granular kudzera munjira monga calendering, casting, blowing, ndi covering. Pakati pawo, njira yosungunula ndi extrusion ndi njira yodziwika bwino. Choyamba, polyurethane imasakanizidwa ndi zowonjezera zosiyanasiyana, monga plasticizers kuti iwonjezere kusinthasintha, stabilizers kuti iwonjezere kutentha ndi kukana kuwala, ndi pigments kuti ipange utoto. Kenako, imatenthedwa ndi kusungunuka, ndipo pamapeto pake imakakamizidwa kudzera mu die kuti ipange filimu yopitilira, yomwe imaziziritsidwa ndikuzunguliridwa kukhala mpukutu. Njira yozizira ndi yofunika kwambiri chifukwa imakhudza kupangika kwa mamolekyu a TPU, motero zimakhudza mawonekedwe omaliza a filimuyo. 3. Makhalidwe Abwino 3.1 Kapangidwe Kathupi Makanema a TPU ali ndi kusinthasintha kwabwino komanso kusinthasintha, ndipo amatha kutambasulidwa ndikusinthidwa mpaka pamlingo winawake, ndipo amatha kubwerera ku mawonekedwe awo oyambirira popanda kusintha, komwe kuli koyenera pazochitika zomwe zimafuna kupindika ndi kupindika pafupipafupi. Mwachitsanzo, popanga zamagetsi osinthasintha, makanema a TPU amatha kutsagana ndi malo opindika a zida. Nthawi yomweyo, ilinso ndi mphamvu yayikulu yolimba komanso mphamvu yolimbana ndi kung'ambika, zomwe zimatha kukana kukhudzidwa ndi kuwonongeka kwakunja. Izi zimapangitsa makanema a TPU kukhala oyenera kugwiritsidwa ntchito mu ma CD oteteza, komwe amafunika kupirira kugwiridwa molakwika. 3.2 Kapangidwe Kamankhwala Makanema a TPU ali ndi kukana bwino kwa mankhwala, ndipo amalekerera ma acid wamba, alkalis, solvents, ndi zina zotero, ndipo samakhala osavuta kuwononga. Makamaka, kukana kwa hydrolysis kwa mafilimu a polyether - mtundu wa TPU kumawalola kuti azigwira ntchito bwino m'malo okhala ndi madzi ambiri. Izi zimapangitsa kuti akhale abwino kugwiritsa ntchito monga zophimba pansi pa madzi ndi nembanemba zosalowa madzi. 3.3 Kukana NyengoMakanema a TPUamatha kusunga magwiridwe antchito okhazikika m'malo osiyanasiyana otentha. Sizosavuta kukhala zolimba komanso zofooka m'malo otentha kwambiri, komanso sizisavuta kufewa ndi kusinthasintha m'malo otentha kwambiri. Alinso ndi mphamvu zina zopewera kuwala kwa ultraviolet, ndipo sizivuta kukalamba ndi kuzimiririka mukamayang'ana kuwala kwa nthawi yayitali. Izi zimapangitsa mafilimu a TPU kukhala oyenera kugwiritsidwa ntchito panja, monga zokongoletsa zakunja zamagalimoto ndi zophimba mipando yakunja. 4. Njira Zazikulu Zokonzera Njira zazikulu zokonzeraMakanema a TPUkuphatikiza kuumba, kuumba, ndi kuumba. Kupyolera mu kuumba, mafilimu a TPU okhala ndi makulidwe ndi m'lifupi osiyanasiyana amatha kupangidwa mwa kudzaza chubu chosungunuka cha TPU. Kuumba kumaphatikizapo kutsanulira mawonekedwe a TPU amadzimadzi pamalo osalala ndikulola kuti aume. Kuumba kumagwiritsa ntchito ma rollers kuti akanikizire ndi kupanga TPU kukhala filimu ya makulidwe omwe mukufuna. Njirazi zimatha kupanga mafilimu a TPU okhala ndi makulidwe, m'lifupi, ndi mitundu yosiyanasiyana kuti akwaniritse zosowa za mitundu yosiyanasiyana yogwiritsira ntchito. Mwachitsanzo, mafilimu a TPU owonda komanso owonekera nthawi zambiri amagwiritsidwa ntchito popaka, pomwe mafilimu okhuthala komanso amitundu angagwiritsidwe ntchito pokongoletsa. 5. Magawo Ogwiritsira Ntchito Mafilimu a TPU amatha kuwonjezeredwa ndi nsalu zosiyanasiyana kuti apange nsalu zapamwamba za nsapato zokhala ndi ntchito zosalowa madzi komanso zopumira, kapena nsalu zokongoletsera, zomwe zimagwiritsidwa ntchito kwambiri mu zovala wamba, zovala zoteteza dzuwa, zovala zamkati, zovala zamvula, zotchingira mphepo, malaya a T, zovala zamasewera ndi nsalu zina. Mu zamankhwala,Makanema a TPUamagwiritsidwa ntchito pazinthu monga zophimba mabala ndi zophimba zida zachipatala chifukwa chakuti zimagwirizana ndi chilengedwe. Kuphatikiza apo, TPU yagwiritsidwanso ntchito kwambiri pazinthu zopangira nsapato, zoseweretsa zopumira mpweya, zida zamasewera, zida za mipando yamagalimoto, maambulera, masutukesi, zikwama zam'manja ndi zina. Mwachitsanzo, pazinthu zamasewera, makanema a TPU amagwiritsidwa ntchito popanga mapepala oteteza ndi zogwirira, zomwe zimapangitsa kuti zikhale zotonthoza komanso zolimba.
