I-Thermoplastic polyurethane (TPU)sisixhobo sokusebenza okuphezulu esinokuguqula usetyenziso lwelaphu ukusuka kwimisonto elukiweyo, amalaphu angangeni manzi, kunye namalaphu angalukwanga ukuya kwisikhumba sokwenziwa. I-TPU esebenzayo emininzi iyazinza ngakumbi, ngokuchukumisa okukhululekile, ukuqina okuphezulu, kunye noluhlu lwezinto ezixubileyo kunye nobunzima.
Okokuqala, iimveliso zethu ze-TPU zine-elasticity ephezulu, ukuqina, kunye nokumelana nokunxiba, okuthetha ukuba amalaphu angaphinda asetyenziswe ngaphandle kokuguqulwa. Ukuchasa i-oyile, ukumelana neekhemikhali, kunye nokuchasana kwe-UV kwenza i-TPU ibe yinto yendalo yokuzikhethela kwizicelo zangaphandle.
Ukongeza, ngenxa ye-biocompatibility, ukuphefumla, kunye neempawu zokufunxa ukufuma kwezinto, abanxibi bakhetha ukukhetha amalaphu e-polyurethane (PU) alula ngokuchukumisa kunye nokomileyo.
Impilo yemathiriyeli inokwandiswa kwinto yokuba i-TPU inokuphinda isetyenziswe kwakhona, kunye neenkcukacha ezisuka kwi-soft kakhulu ukuya kunzima kakhulu. Xa kuthelekiswa nezinye iindlela, esi sisisombululo semathiriyeli esinye esizinzileyo. Ikwanesiqinisekiso somxholo we-volatile organic compound (VOC), enokunciphisa izinto ezikhutshwayo eziyingozi.
I-TPU inokulungelelaniswa ukuba ibe neepropati ezithile ezifana nokungangeni kwamanzi okanye ukuchasana kweekhemikhali zoshishino. Ngokuchaneke ngakumbi, le mathiriyeli inokulungelelaniswa ngeendlela ezithile zokusetyenzwa, ukusuka ekulukeni komsonto ukuya ekubumbeni, ukukhutshwa, kunye noshicilelo lwe-3D, ngokwenza oko lula uyilo oluntsonkothileyo kunye nemveliso. Nazi izicelo ezininzi ezigqwesileyo iTPU.
Isicelo: Ukusebenza okuninzi, ukusebenza okuphezuluTPU umsonto
I-TPU inokuveliswa ibe yimisonto ye-filament eyodwa okanye ezimbini, kunye nezisombululo zemichiza zisetyenziswa phantse kuzo zonke iimeko (96%). Ukudaya nge-anhydrous kunokunciphisa impembelelo yokusingqongileyo yeenkqubo zokuvelisa. Ngokwahlukileyo, xa kunyibilika ukusonta, izisombululo azisoloko zisetyenziswa, ke ezi zisombululo zinokukhutshwa okuphantsi okanye akukho VOC. Ukongeza, i-melt spinning inesikhumba esithambileyo.
Isicelo: Ilaphu lelaphu leTPU elingangenwa manzi, lisetyenziselwa izigqubuthelo zelori, iingxowa zebhayisekile, kunye nesikhumba sokwenziwa
I-TPU ayinamanzi kwaye iyaxhathisa ibala. Idityaniswe nobomi bayo obandisiweyo, itekhnoloji yeTPU lolona khetho lufanelekileyo kwizicelo ezinzima ezinje ngamalaphu angangeni manzi elorini, iingxowa zebhayisekile, kunye nesikhumba sokwenziwa. Olunye uncedo olubalulekileyo kukuba i-thermoplastic polyurethane kulula ukuyiphinda isetyenziswe kunezixhobo ezininzi ezikhoyo zamalaphu angangeni manzi.
Akukho zisombululo zekhemikhali ezisetyenziswa kwiinkqubo ze-thermoplastic ezifana nokuqengqeleka okanye i-T-die extrusion ukuqinisekisa ukuncitshiswa okanye ukupheliswa ngokupheleleyo kwee-VOCs. Kwangaxeshanye, akukho mfuneko yokusela amanzi ukuhlamba iikhemikhali ezigqithisileyo, eyinxalenye eqhelekileyo yonyango lwesisombululo.
Isicelo: Ulusu lwe-TPU elomeleleyo kwaye lunokuphinda lusetyenziswe
Ukubonakala kunye nokuvakalelwa kwesikhumba sokwenziwa kunzima ukwahlula kwisikhumba sendalo, kwaye kwangaxeshanye, imveliso inombala ongenamkhawulo kunye nokukhetha kokuthungwa komphezulu, kunye nokuchasana kwe-oyile ye-TPU yendalo, ukuxhathisa igrisi, kunye nokumelana nokunxiba. Ngenxa yokungabikho kwaso nasiphi na isilwanyana esivela kwizinto eziluhlaza, i-TPU yesikhumba yokwenziwa ifanelekile kakhulu kubantu abatya imifuno. Ekupheleni kwesigaba sokusetyenziswa, isikhumba esekwe kwi-PU sinokuphinda sisetyenziswe ngoomatshini.
Isicelo: Ilaphu elingalukwanga
Indawo yokuthengisa ekhethekileyo ye-TPU engalukwanga ilaphu kukuchukunyiswa kwayo okukhululekileyo kunye nokuthambileyo, kunye nokukwazi ukugoba ngokuphindaphindiweyo, ukolula, kunye nokuguquguquka kuluhlu olubanzi lobushushu ngaphandle kokuqhekeka.
Ngokukodwa ifanelekile kwimidlalo kunye nezicelo zempahla yokunxiba, apho imicu ye-elastic inokudityaniswa kwisakhiwo se-mesh esiphefumla kakhulu, okwenza kube lula ukuba umoya ungene kunye nokubila ukuba kukhutshwe.
Inkumbulo yobume inokuthi iyilwe ibe yi-TPU polyester yelaphu elingalukwanga, elinendawo ephantsi yokunyibilika ithetha ukuba inokucinezelwa kushushu kwamanye amalaphu. Iindidi ezahlukeneyo ezinokuphinda zisetyenziswe, zisekwe ngokuyinxenye kwibhayoloji, nezingonakali zingasetyenziswa kwizinto zamalaphu ezingalukwanga.
