Amakhasimende amaningi abike ukuthi i-TPU ebonakala kalula iyabonakala uma yenziwa okokuqala, kungani iba nombala ofana nowelayisi ngemva kwezinsuku ezimbalwa? Eqinisweni, i-TPU inesici semvelo, okuwukuthi iphenduka kancane kancane ibe phuzi ngokuhamba kwesikhathi. I-TPU imunca umswakama emoyeni bese iba mhlophe, noma lokhu kungenxa yokufuduka kwezithasiselo ezingeziwe ngesikhathi sokucubungula. Isizathu esiyinhloko ukuthi i-lubricant ayibonakali, kanti ukuba phuzi kuyisici se-TPU.
I-TPU iyi-resin ephuzi, futhi i-MDI ku-ISO izophenduka ibe phuzi ngaphansi kokukhanya kwe-UV, okubonisa ukuthi i-TPU iphuzi iyisici. Ngakho-ke, sidinga ukulibazisa isikhathi se-TPU sokuba phuzi. Ngakho-ke singayivimbela kanjani i-TPU ekubeni phuzi?
Indlela 1: Gwema
1. Khetha ukuthuthukisa imikhiqizo emnyama, ephuzi, noma enombala omnyama esigabeni sokuqala sokuthuthukisa imikhiqizo emisha. Ngisho noma le mikhiqizo ye-TPU iphenduka iphuzi, ukubukeka kwayo akubonakali, ngakho-ke ngokwemvelo akukho nkinga yokuphuzi.
2. Gwema ukuchayeka elangeni ngqo ku-PU. Indawo yokugcina i-PU kufanele ipholile futhi ingeniswe umoya, futhi i-PU ingasongwa ngezikhwama zepulasitiki bese ibekwa endaweni engenakukhanya kwelanga.
3. Gwema ukungcola ngesikhathi sokusebenza ngesandla. Imikhiqizo eminingi ye-PU ingcolisiwe ngesikhathi senqubo yokuhlunga noma yokusindisa, okuholela ekuphuzeni okufana nokujuluka komuntu kanye nezinyibilikisi eziphilayo. Ngakho-ke, imikhiqizo ye-PU kufanele inake kakhulu ukuhlanzeka komzimba wokuthintana futhi inciphise inqubo yokuhlunga ngangokunokwenzeka.
Indlela 2: Ukwengeza izithako
1. Khetha ngqo izinto ze-TPU ezihlangabezana nezimfuneko zokumelana ne-UV.
2. Faka ama-anti-yellowing agents. Ukuze kuthuthukiswe ikhono lokulwa nokuphuzi kwemikhiqizo ye-PU, kuvame ukudingeka ukwengeza i-anti-yellowing agent ekhethekile ezintweni zokusetshenziswa. Kodwa-ke, ama-anti-yellowing agents ayabiza, futhi kufanele sicabangele nezinzuzo zawo zomnotho lapho siwasebenzisa. Isibonelo, umzimba wethu omnyama awuzweli ekuphuzini, ngakho-ke singasebenzisa izinto zokusetshenziswa ezingabizi kakhulu ezingalwi nokuphuzi ngaphandle kwama-anti-yellowing agents. Njengoba ama-anti-yellowing agents eyisithasiselo sezinto zokusetshenziswa ezingeziwe engxenyeni A, sidinga ukuxuba lapho sixuba ukuze sifinyelele ukusatshalaliswa okufanayo kanye nomphumela wokulwa nokuphuzi, ngaphandle kwalokho ukuphuzi kwendawo kungase kwenzeke.
3. Futha upende ophuzi omelana nokushisa. Ngokuvamile kunezinhlobo ezimbili zokufutha ngopende, enye isekufutheni ngesikhunta kanti enye ingaphandle kokufuthanisela ngesikhunta. Ukufutha ngopende ophuzi omelana nokushisa kuzokwakha ungqimba oluvikelayo ebusweni bemikhiqizo eqediwe ye-PU, kugweme ukungcola kanye nokuphuzi okubangelwa ukuthintana kwesikhumba se-PU nomoya. Lolu hlobo lusetshenziswa kabanzi njengamanje.
Indlela 3: Ukufakwa esikhundleni kwezinto
Iningi le-TPU yi-TPU enephunga elimnandi, equkethe izindandatho ze-benzene futhi ingamunca kalula ukukhanya kwe-ultraviolet futhi ibangele ukuphuzi. Lesi yisizathu esiyisisekelo sokwephuzi kwemikhiqizo ye-TPU. Ngakho-ke, abantu embonini babheka i-anti ultraviolet, anti yellowing, anti-aging kanye ne-anti ultraviolet ye-TPU njengomqondo ofanayo. Abakhiqizi abaningi be-TPU bathuthukise i-TPU entsha ye-aliphatic ukuxazulula le nkinga. Ama-molecule e-Aliphatic TPU awaqukethe izindandatho ze-benzene futhi anokuqina okuhle kwe-photostability, awalokothi aphenduke aphuzi.
Vele, i-TPU ye-aliphatic nayo inezinkinga zayo namuhla:
1. Ububanzi bobulukhuni buncane kakhulu, ngokuvamile buphakathi kuka-80A-95a
2. Inqubo yokucubungula icocekile kakhulu futhi kulula ukuyicubungula
3. Ukuntuleka kokubonakala, kungafinyelela kuphela ukucaca okungu-1-2mm. Umkhiqizo ojiyile ubukeka unenkungu kancane
