Iindaba - I-Si‑TPV Modifier Yomeleza Ukumelana Nokunxitywa KweTPU Kwizinto Ezinxitywayo Ezihlala Ixesha Elide NeziThambileyo

I-TPU Wearable Device Elastomer, Izinto zeBand zeWotshi ezithambileyo njengesikhumba, Izinto ze-Elektroniki ezinxitywayo

Ukuphucula ukuxhathisa ukunxitywa kweTPU: Izisombululo zezinto ezinxitywayo, iintambo, kunye nezinye iimveliso ezigqityiweyo

Kwimarike yanamhlanje ekhuphisanayo, i-thermoplastic polyurethane (TPU) isetyenziswa kakhulu kwizicelo ezifuna amandla ezifana neejakethi zekhebula zabathengi, iibhanti zemizi-mveliso, ii-escalator handrails, iibhendi zezixhobo ezinokunxitywa, kunye nezinye izinto eziguquguqukayo. Ezi meko zokusetyenziswa azifuni kuphela iimpawu zoomatshini nezomeleleyo kodwa zikwafuna nokumelana nokukrazuka okungaqhelekanga kwaye, kwiimeko ezininzi, i-coefficient echaziweyo yokukrazuka.

Sekunjalo uninzi lwee-OEM kunye nee-compounders zifumanisa ukuba nee-TPU zeprimiyamu zinokonakaliswa ngumphezulu, ukuguguleka kokungqubana, ukuziphatha kokunamathela nokutyibilika, okanye ukusilela kwangethuba phantsi kweemeko zokugoba ngebhayisikile.

Kwiinjineli kunye namaqela oyilo, umbuzo ophambili uba ngulo:Singaluphucula njani ukuqina kweTPU ngaphandle kokuphazamisa ukuthamba, ukugqitywa kokubonakalayo, okanye ukuqhubekeka kokusebenza?

Izisombululo Zemveli kunye Nemida Yazo

Kwiminyaka edlulileyo, ii-compounders ziye zajongana neengxaki zokuguguleka kweTPU ngeendlela ezintathu eziphambili:
• Izongezo zokuthambisa okanye ezichasene nokungqubana — umz., i-PTFE, i-molybdenum disulfide, okanye iinkqubo ezisekwe kwi-wax ezinciphisa ukungqubana komphezulu kodwa ezinokufuduka okanye zichaphazele ukuvakala komphezulu.
• Izizalisi eziqinileyo ezingagugiyo — umz., amasuntswana e-ceramic okanye ii-glass beads, ezinokuphucula ukumelana nokuguguleka kodwa zihlala zonyusa ubulukhuni okanye zinciphise ukuguquguquka.
• Iinkqubo ze-micro-crosslinking okanye ze-reactive — ezijolise ekuvaleleni isakhiwo kwaye zixhathise ukuguquka komphezulu, kodwa zihlala ziphazamisa ukuphinda kusetyenziswe okanye ukwenza kube nzima ukujova/ukubumba ngaphezulu.

Indlela nganye kwezi ineenzuzo, kuquka ukufuduka ngokuhamba kwexesha, ukuqhakaza komphezulu, ukulahleka kokuthamba, ukunciphisa ukugqitywa kobuhle/ukuchukumisa ulusu, okanye iingxaki zokucubungula. Njengoko usetyenziso lusiya lusanda ukuya kwizinto ezinxitywayo, iintambo, kunye neeprofayili ezincinci eziguquguqukayo, kukho imfuno ekhulayo yesixhobo sokuguqula esigcina ukuguquguquka, umgangatho womphezulu, kunye nokusebenza kokunxitywa kwexesha elide.

Ukwazisa iindlela ezintsha nezisebenzayo zokunganxibi kwi-TPU Compounders

Inkqubela yakutshanje kwi-elastomers ezisekelwe kwi-thermoplastic silicone ezisebenzisa i-dynamic vulcanized thermoplastic(i-Si‑TPV) inika isisombululo esisisigxina sokumelana nokuguguleka kwe-TPU, ukoyisa imida yeendlela zemveli.

Le Thermoplastic Elastomer esekelwe kwisilicone yenziwe ngetekhnoloji ekhethekileyo ehambelanayo ukunceda irabha yesilicone isasazeke kwiTPU ngokulinganayo njengamasuntswana e-1 ~ 3 micron phantsi kwemicroscope. Le nto ikhethekileyo idibanisa amandla, ukuqina, kunye nokumelana nokurhawuzelelwa kwayo nayiphi na i-thermoplastic elastomer kunye neempawu ezinqwenelekayo zesilicone: ukuthamba, ukuvakala kwesilika, ukukhanya kwe-UV, kunye nokumelana neekhemikhali, ezinokuphinda zisetyenziswe kwaye zisetyenziswe kwakhona kwiinkqubo zemveli zokuvelisa.

Ngokongeza isixa esifanelekileyo seIsiguquli se-Si‑TPV 3100-55AKwii-thermoplastic polyurethane (TPU) elastomers, ii-compounders zinokufikelela ekuchaseni okuphuculweyo kokurhawuzelelwa, uzinzo oluphuculweyo loomatshini phantsi koxinzelelo olujikelezayo, kunye nokugqitywa okuthambileyo okuchukumisayo okunobuhlobo nolusu okunesiphumo esithambileyo—konke oku ngaphandle kweengxaki eziqhele ukunxulunyaniswa nee-lubricants, ii-hard fillers, okanye iinkqubo zokudibanisa, ezifana nokufuduka ngokuhamba kwexesha, ukuqhakaza komphezulu, ukulahleka kokuthamba, okanye ukuncipha kweempawu zobuhle kunye nokuchukumisa ulusu.

Ngokwengxelo yabathengi, uvavanyo lwangaphakathi lubonisa ukwehla kokulahlekelwa kukuguguleka malunga ne-30–75% kunye nokuphuculwa kokumelana nokuguguleka kwe-2–3× xa kuthelekiswa neekhompawundi zeTPU eziqhelekileyo phantsi kweemeko zovavanyo lwenkampani—okungaphezulu kakhulu kokusebenza kweeTPU eziqhelekileyo ezingagugulekiyo kwimarike.

Indlela i-Si‑TPV Eyinika Ngayo Ukumelana Nokunxitywa Okungapheliyo kwi-TPU？

Iindlela eziphambili zokuguqula umphezulu we-Si‑TPV ukuphucula ukuqina kwe-TPU kunye nokusebenza kwe-Tactile

Ngokusebenzisa itekhnoloji yokuhambelana ekhethekileyo kunye ne-dynamic vulcanization, ii-particles zerabha ze-silicone (1–3 μm) zisasazeka ngokulinganayo ngaphakathi kwi-TPU matrix, zenze imo eyahlukileyo "yesiqithi solwandle". Ezi particles zinkulu ngobukhulu be-micron zenza ii-micro-protrusions kumphezulu we-TPU, zivelisa imvakalelo yokuchukumisa ethambileyo, egudileyo, nenobuhlobo nolusu.

Olu lwakhiwo ludibanisa amandla oomatshini kunye nokuguquguquka kweTPU kunye neempawu eziphambili zokuchukumisa zerabha ye-silicone, ngelixa kuqinisekiswa ukuba amasuntswana e-silicone ahlala esasazwa ngokulinganayo nangokuzinzileyo ngaphakathi kwe-matrix.

Amasuntswana erabha e-silicone athambileyo ngokwemvelo, asebenza njengeenxalenye ezithambileyo ze-thermoplastic elastomer, nto leyo enciphisa ubulukhuni be-TPU. Oku kususa imfuneko yee-plasticizers zangaphandle, kuthintela imiba yokufuduka kweoyile kumthombo kwaye kuxhasa ukuthembeka komphezulu ixesha elide ngelixa kuxhathisa ukunamathela komphezulu.

I-Si‑TPV iqulethe umlinganiselo omkhulu werabha ye-silicone edibeneyo enee-crosslinked enamandla aphantsi omphezulu, nto leyo enciphisa i-coefficient of friction kunye ne-abrasion yezinto ezidityanisiweyo.

Ngenxa yokuba irabha ye-silicone edibeneyo ayishukumi ngaphakathi kwi-TPU matrix kubushushu begumbi, ukumelana nokuguguleka okubangelwa yiyo kuhlala kuhleli kwaye kuyafana, ngaphakathi nangaphandle.

Ngokungafaniyo nezinto zokuthambisa ezifana nee-linear siloxanes okanye ii-waxes, eziphelelwa ngamandla xa umaleko wazo wokuthambisa uphela, i-Si‑TPV inika ukumelana nokuguguleka okuhlala ixesha elide.

Iingcebiso Ezisebenzayo Zokusebenzisa: Xuba i-Si‑TPV kwi-TPU yakho esisiseko ngedosi elawulwayo (umz., indawo yokuqala eqhelekileyo ye-5–10 wt%. Gcina iimeko zokucubungula ezifana nezenkqubo yakho ye-TPU ukuqinisekisa ukusasazeka okuhle.

Ukuba ungumntu odibanisa izinto ezidityanisiweyo okanye i-OEM ejongene nemingeni yokuguguleka kweTPU—njengokudinwa yi-cable flex, ukurhawuzelelwa komphezulu kunye nokunamathela kwiimpahla ezinxitywayo, okanye usetyenziso oluthambileyo olugobileyo—Izinto zokuchukumisa ezithambileyo nezithambileyo ezithambileyo nezinobuhlobo nolusu ixesha elideinokukunceda:

• Yenza ukuba ukuguguleka kube yinto engapheliyo

• Gcina ukugqitywa okuthambileyo, okunobuhlobo nolusu okuchukumisayo okunesiphumo esithambileyo

• Ukusebenziseka lula
