Abathengi abaninzi baye baxela ukuba i-TPU ecacileyo kakhulu iyabonakala xa yenziwe okokuqala, kutheni ingabonakali emva kosuku kwaye ibonakale ifana nombala werayisi emva kweentsuku ezimbalwa? Enyanisweni, i-TPU inesiphene sendalo, esikukuba ijika ibe mthubi kancinci kancinci ngokuhamba kwexesha. I-TPU ifunxa umswakama emoyeni ize ibe mhlophe, okanye oku kungenxa yokufuduka kwezongezo ezongeziweyo ngexesha lokucubungula. Isizathu esiphambili kukuba i-lubricant ayibonakali, kwaye ukuba mthubi luphawu lwe-TPU.
I-TPU yi-resin etyheli, kwaye i-MDI kwi-ISO iya kuba tyheli phantsi kokukhanya kwe-UV, nto leyo ebonisa ukuba i-TPU yetyheli yimpawu. Ke ngoko, kufuneka silibazise ixesha lokuba tyheli kwe-TPU. Ngoko ke singayithintela njani i-TPU ekubeni ibe tyheli?
Indlela 1: Kuphephe
1. Khetha ukuphuhlisa iimveliso ezimnyama, ezimthubi, okanye ezimnyama kwinqanaba lokuqala lokuvelisa iimveliso ezintsha. Nokuba ezi mveliso zeTPU zijika zibe mthubi, imbonakalo yazo ayinakubonwa, ngoko ke ngokwemvelo akukho ngxaki yokuba tyheli.
2. Kuphephe ukuvezwa elangeni ngqo kwi-PU. Indawo yokugcina i-PU kufuneka ipholile kwaye ingene umoya, kwaye i-PU ingasongelwa kwiingxowa zeplastiki ize ibekwe kwindawo engenakuvezwa elangeni.
3. Kuphephe ukungcoliswa ngexesha lokusebenza ngesandla. Iimveliso ezininzi ze-PU zingcoliswa ngexesha lenkqubo yokuhluza okanye yokucoca, nto leyo ebangela ukuba zibe tyheli njengokubila komntu kunye nezinyibilikisi zendalo. Ke ngoko, iimveliso ze-PU kufuneka ziqwalasele ngokukodwa ukucoceka komzimba odibanayo kwaye zinciphise inkqubo yokuhluza kangangoko kunokwenzeka.
Indlela yesi-2: Ukongeza izithako
1. Khetha ngokuthe ngqo izinto zeTPU ezihlangabezana neemfuno zokuxhathisa i-UV.
2. Yongeza ii-arhente ezichasene nokutyheli. Ukuze kuphuculwe amandla okutyheli kweemveliso ze-PU, kudla ngokuba yimfuneko ukongeza i-arhente ekhethekileyo yokulwa nokutyheli kwizinto eziluhlaza. Nangona kunjalo, ii-arhente ezichasene nokutyheli zibiza kakhulu, kwaye kufuneka siqwalasele neenzuzo zazo zoqoqosho xa sizisebenzisa. Umzekelo, umzimba wethu omnyama awunangxaki nokutyheli, ngoko ke singasebenzisa izinto eziluhlaza ezingabizi kakhulu ngaphandle kwee-arhente ezichasene nokutyheli. Njengoko ii-arhente ezichasene nokutyheli zizinto ezongeziweyo kwi-component A, sifuna ukuxutywa xa kuxutywa ukuze kufezekiswe usasazo olufanayo kunye nesiphumo sokuchasana nokutyheli, kungenjalo ukutyheli kwendawo kunokwenzeka.
3. Ipeyinti etyheli enganyangekiyo. Ngokwesiqhelo kukho iindlela ezimbini zokutshiza ipeyinti, enye ikwi-mold spray kwaye enye ingaphandle kwe-mold spray. Ukutshiza ipeyinti etyheli enganyangekiyo kuya kwenza umaleko okhuselayo kumphezulu weemveliso ezigqityiweyo ze-PU, kuthintelwe ungcoliseko kunye nokutyheli okubangelwa kukudibana kolusu lwe-PU nomoya-moya. Olu hlobo lusetyenziswa kakhulu okwangoku.
Indlela 3: Ukutshintshwa kwezinto
Uninzi lwe-TPU yi-TPU enevumba elimnandi, equlethe imisesane ye-benzene kwaye inokufunxa ukukhanya kwe-ultraviolet kwaye ibangele ukuba tyheli. Esi sesona sizathu siphambili sokuba iimveliso ze-TPU zibe tyheli. Ke ngoko, abantu abakwishishini bajonga i-anti ultraviolet, anti tyheli, anti-aging kunye ne-anti ultraviolet ye-TPU njengengcamango efanayo. Abavelisi abaninzi be-TPU baphuhlise i-TPU entsha ye-aliphatic ukusombulula le ngxaki. Iimolekyuli ze-Aliphatic TPU azinazo imisesane ye-benzene kwaye zinokuzinza okuhle kwe-photostability, azize zijike zibe tyheli.
Ewe, i-TPU ye-aliphatic ikwanazo neengxaki zayo namhlanje:
1. Uluhlu lobunzima luncinci kakhulu, ngokubanzi luphakathi kwe-80A-95a
2. Inkqubo yokucubungula icwangciswe kakuhle kwaye kulula ukuyicubungula
3. Ukungabikho kokubonakala, kunokufikelela kuphela kukukhanya kwe-1-2mm. Imveliso etyebileyo ibukeka inenkungu kancinci
