Uhlalutyo olupheleleyo lweI-TPU PelletUbulukhuni: Iiparameter, Izicelo kunye namanyathelo okuphepha okusetyenziswa
I-TPU (i-Thermoplastic Polyurethane), njengesixhobo se-elastomer esisebenza kakuhle, ubulukhuni beepellets zayo yiparameter ephambili emisela ukusebenza kwesixhobo kunye neemeko zokusetyenziswa kwaso. Uluhlu lobulukhuni beepellets zeTPU lubanzi kakhulu, luhlala luqala kwi-60A ethambileyo kakhulu ukuya kwi-70D elukhuni kakhulu, kwaye amanqanaba obulukhuni ahlukeneyo ahambelana neempawu zomzimba ezahlukeneyo ngokupheleleyo.Okukhona ubulukhuni buphezulu, kokukhona ukuqina kunye nokumelana nokuguquguquka kwezinto, kodwa ukuguquguquka kunye nokuguquguquka kuya kuncipha ngokufanelekileyo; ngokuchaseneyo, i-TPU enobunzima obuphantsi igxila ngakumbi ekuthambekeni nasekubuyiseleni i-elastic.
Ngokuphathelele ukulinganisa ubulukhuni, ii-durometers zeShore zisetyenziswa kakhulu kushishino lokuvavanya. Phakathi kwazo, ii-durometers zeShore A zifanelekile kuluhlu lobunzima obuphakathi nobuphantsi be-60A-95A, ngelixa ii-durometers zeShore D zisetyenziswa kakhulu kwi-TPU enobunzima obuphezulu ngaphezu kwe-95A. Landela ngokungqongqo iinkqubo eziqhelekileyo xa ulinganisa: okokuqala, faka ii-pellets ze-TPU kwiziqwenga zovavanyo ezithe tyaba ezinobukhulu obungaphantsi kwe-6mm, uqinisekise ukuba umphezulu awunaziphene ezifana namaqamza kunye nemikrwelo; emva koko vumela iziqwenga zovavanyo zime kwindawo enobushushu obuyi-23℃±2℃ kunye nokufuma okulinganiselweyo kwe-50%±5% iiyure ezingama-24. Emva kokuba iziqwenga zovavanyo zizinzile, cinezela i-indenter ye-durometer ngokuthe nkqo kumphezulu wesiqwenga sovavanyo, uyigcine imizuzwana emi-3 uze ufunde ixabiso. Kwiqela ngalinye leesampuli, linganisa ubuncinci amanqaku ama-5 kwaye uthathe umyinge ukunciphisa iimpazamo.
Yantai Linghua New Material CO.,LTD.inomgca opheleleyo wemveliso ogubungela iimfuno zobunzima obahlukeneyo. Iipellets zeTPU zobunzima obahlukeneyo zinezahlulo ezicacileyo zomsebenzi kwiindawo zokusetyenziswa:
- Ngaphantsi kwe-60A (ethambile kakhulu)Ngenxa yokuchukumisa kwazo okugqwesileyo kunye nokuthamba kwazo, zihlala zisetyenziswa kwiimveliso ezineemfuno eziphezulu kakhulu zokuthamba ezifana neethoyi zabantwana, iibhola zokubamba ezixinanisiweyo, kunye nee-insole linings;
- 60A-70A (ethambileyo): Ukulinganisela ukuguquguquka kunye nokumelana nokuguguleka, yinto efanelekileyo kwiintsika zezihlangu zemidlalo, iiringi zokuvala ezingangeni manzi, iityhubhu zokufaka kunye nezinye iimveliso;
- 70A-80A (ethambileyo phakathi): Ngokusebenza okulinganayo okubanzi, isetyenziswa kakhulu kwiimeko ezifana neesheath zekhebula, izigqubuthelo zamavili okuqhuba eemoto, kunye neetourniquets zonyango;
- 80A-95A (phakathi-nzima ukuya koluqinileyo): Ukulinganisela ubulukhuni kunye nokuqina, ifanelekile kwizinto ezifuna amandla athile okuxhasa afana neerola zeprinta, amaqhosha okulawula umdlalo, kunye neekheyisi zefowuni ephathwayo;
- Ngaphezulu kwe-95A (eqinile kakhulu): Ngenxa yokuba inamandla aphezulu kwaye ixhathisa impembelelo, iye yaba yeyona nto ikhethwayo kwiigiya zoshishino, izikhuselo zoomatshini, kunye nee-shock pads zezixhobo ezinzima.
Xa usebenzisaIipellets zeTPU,la manqaku alandelayo kufuneka aqatshelwe:
- Ukuhambelana kweekhemikhali: I-TPU inovelwano kwizinyibilikisi ze-polar (ezifana notywala, i-acetone) kunye nee-asidi ezinamandla kunye ne-alkalis. Ukudibana nazo kunokubangela ukudumba okanye ukuqhekeka ngokulula, ngoko ke kufuneka kuthintelwe kwiindawo ezinjalo;
- Ulawulo lobushushu: Ubushushu bokusetyenziswa ixesha elide akufuneki budlule kwi-80℃. Ubushushu obuphezulu buya kukhawulezisa ukuguga kwezinto. Ukuba zisetyenziswa kwiimeko zobushushu obuphezulu, kufuneka kusetyenziswe izongezo ezimelana nobushushu;
- Iimeko zokugcina: Le nto icocekile kakhulu kwaye kufuneka igcinwe kwindawo evaliweyo, eyomileyo nengena umoya enomswakama olawulwa yi-40%-60%. Ngaphambi kokuba isetyenziswe, kufuneka yomiswe kwi-oven engama-80℃ iiyure ezi-4-6 ukuthintela amaqamza ngexesha lokucubungula;
- Ukulungiswa kokulungiswa: I-TPU yobunzima obahlukeneyo kufuneka ihambelane neeparamitha ezithile zenkqubo. Umzekelo, i-TPU eqinileyo kakhulu kufuneka yonyuse ubushushu bebharele ukuya kwi-210-230℃ ngexesha lokubumba ngenaliti, ngelixa i-TPU ethambileyo kufuneka inciphise uxinzelelo ukuze iphephe ukukhanya.
