Ukuphumelela kwindlela yokuziva i-elastomeric, ukumelana nokugoba, kunye nokusebenza komphezulu olungele ulusu
Njengoko imfuno isanda yeefilimu eziguquguqukayo ezisebenza kakuhle kwizicelo zonyango, zoshishino, kunye nezinxitywayo, abavelisi bafuna izixhobo ezinokubonelela ngomxube ongaqhelekanga weukuthamba okuthambileyo, ukusebenza kwe-drape, ukumelana nokugoba, kunye nokuzinza kokucubungulaKule meko,I-Si-TPV 3100-55A, inkqubo yokuguqula i-thermoplastic esekwe kwi-silicone kunye ne-TPU, ibonisa amandla amakhulu kwizicelo zokukhupha ifilimu eziqhumayo, kuquka neefilimu eziguquguqukayo zezinga lezonyango.
Imfuno Ekhulayo Yeshishini: Ukusuka Kwiifilimu Ezisebenzayo ukuya “Kwii-Soft Elastomeric Experience”
Kuzo zonke izinto ezisetyenziswayo kwezonyango, iifilimu zokukhusela, kunye nokupakishwa okuguquguqukayo kwemizi-mveliso, imakethi itshintshela kwizinto ezingasebenzi nje kuphela ngokoomatshini kodwa neziphuculaamava okusebenzisa umsebenzisi kunye nokuqonda okuchukumisayo.
Iiresini zeTPU eziqhelekileyo ezifana ne-aromatic polyether TPU (umz., ii-80–90 Shore A grades ezifana neenkqubo ze-Irogran kunye ne-Texin) zinika amandla kunye nokuguquguquka, kodwa iiprosesa ziyaqhubeka nokujongana nemida kwi:
Le mingeni ibonakala ngakumbi kwiiifilimu ezibhityileyo ezijikeleze i-3 mil (≈76.2 μm), apho ukuzinza kwezinto kunye nokufana komphezulu kuba nzima ngakumbi ukugcina.
I-Si-TPV 3100-55A kwi-TPU Film Processing
I-Si-TPV 3100-55A ingafakwa kwiIinkqubo zefilimu eziqhushumbisiweyo zeTPU, kuquka iifilimu ezinobukhulu obuqhelekileyo obumalungaIimilimitha ezi-3 (76.2 μm), apho isetyenziselwa ukuphucula iimpawu zokuchukumisa okuthambileyo, ukuqonda kwe-elastomeric, kunye nokuvakala komphezulu ngokubanzi wefilimu yokugqibela.
Kolu luhlu lwefilimu oluncinci, inkqubo yokucubungula iba buthathaka ngakumbi kwindlela yokusabalalisa ngezigaba. Ngamanye amaxesha inokubangela ukubaumphezulu okhanyayo "ofana namabala amancinci" okanye inkangeleko efana namaqhekeza, enxulunyaniswa nokuhlanganiswa kwendawo kweendawo ezityebileyo ze-silicone ngexesha lokwenziwa kwefilimu phantsi kweemeko zokutsalwa okuphezulu.
Endaweni yokuba ngumda wezinto ngokwazo, le ndlela yokuziphatha inxulunyaniswa kakhuluukufana kokusasazwa kunye nokusebenza kakuhle kokucoca ngexesha lesigaba sokudibanisa kunye nokufaka iipellet.
Ukuphucula ukuhambelana komphezulu kunye nokufezekisa ukubonakala kwefilimu efanayo, kucetyiswa ukuba kungenisweIsikrini sokucoca i-mesh esingu-250–300 ngexesha lenkqubo yokudibanisa i-melt kunye ne-pelletizingEli nyathelo linceda ukususa ii-agglomerates ezinkulu ezinokubakho ngaphambi kokuba zikhutshwe, ukuqinisekisa inkqubo yokusasazwa ezinzileyo necociweyo engena kumgca wefilimu.
Ngolu hlengahlengiso, abavelisi banokufikelela kwisiphumo esilungeleleneyo phakathi:
- imbonakalo yomphezulu wefilimu egudileyo nehambelanayo
- ukusebenza okuzinzileyo kwe-elastomeric kunye nokusebenza okuthambileyo
- ukuthembeka okuphuculweyo kokucubungula kwiifilimu ze-TPU ezi-thin-gauge
Ngokubanzi, le ndlela yokwenza ngcono inceda iSi-TPV 3100-55A ukuba isebenze kakuhle kwizicelo zefilimu zeTPU ezincinci, ixhasa zombiniukuphuculwa kokuchukumisa kunye nolawulo lomgangatho womphezulu obonakalayokwiindawo ezifuna kakhulu imveliso yeefilimu.
1. Uvakalelo oluphuculweyo lwe-Elastomeric kunye nokusebenza okuthambileyo kokuchukumisa
Kwizicelo zefilimu eziqhumayo, i-Si-TPV 3100-55A iphucula kakhulu ukuthamba okubonakalayo, okuvumela ukubaukuziphatha kwefilimu efana nerabha, ethambileyoxa kuthelekiswa neefomyula zeTPU eziqhelekileyo.
2. Ukuphucula ukuxhathisa ukuqhekeka kunye nokutsaleka kwe-crease
Le nto iphucula ukuguquguquka kwefilimu kunye nokubuyiselwa kwayo, ivumela iifilimu ukuba zibonise:
Ukusebenza ngcono kwedrape
Ukuncipha kokuqonda ukuqina
Ukumelana nokugoba okuphuculweyo phantsi kokugoba nokuphathwa ngokuphindaphindiweyo
Ezi mpawu zibaluleke kakhulu kwiifilimu zonyango nezokukhusela.
3. Isikhokelo Sokucubungula Uzinzo Lwefilimu Encinci
Ngexesha lovavanyo, kwaqatshelwa ukubaIifilimu ezi-3 mil (≈76.2 μm)inokubonakalisa uvakalelo lokusasazeka phantsi kweemeko ezithile, kuquka ukuhlanganiswa kwe-silicone domain encinci.
Nangona kunjalo, ukulungiswa kobugcisa kubonise ukuba:
Uzinzo luphucuka kakhulu kwiUbukhulu befilimu obuyi-≥5 mil
l Kwiifilimu ezincinci,Ukuhlanganiswa kwesigaba esidibeneyo kubalulekile
Ukusetyenziswa kweUkuhluzwa kwe-mesh ezingama-250–300 ngexesha lokucola i-pelletizinginceda ukunciphisa iziphumo zokuhlanganisana kunye nokuphucula ukufana kokusasazeka
4. Izinto ekufuneka ziqwalaselwe ngokungafihlisi nto
Ngenxa yokubakho kwezigaba ze-silicone ezisasazekileyo, iifilimu ezilungisiweyo ze-Si-TPV zinokuba namavaukunciphisa okuphakathi kokukhanya okubonakalayo, kuxhomekeke kwidosi kunye neemeko zokucubungula.
Kuvavanyo lwefilimu yezonyango, iimfuno zomnkungu osisiseko (umz., ~22% umnkungu kunye ~89% ukucaca ngokwe-ASTM D1003 kwiifilimu ezibhekisayo) zizinto ezibalulekileyo zokulinganisa ukwenziwa ngcono kwefomyula.
Ukubaluleka kweShishini: Ukuvumela "iiFilimu zeTPU eziqhutywa ngamava"
Ityala lovavanyo libonisa umkhwa obanzi wophuhliso lwefilimu yepolymer:
Ubuchule bezinto ezibonakalayo abusekho kuphela kumandla oomatshini—buchazwa ngakumbi ngamava okuchukumisa, ukuphatha intuthuzelo, kunye nokuqonda okungaphezulu.
I-Si-TPV 3100-55A ibonisa indlela iinkqubo ze-silicone-TPU hybrid ezinokuwuvala ngayo lo msantsa ngokuvumela:
- Ukuthamba kwe-Elastomeric ngaphandle kweengxaki ze-silicone ezingamanzi
- Ukucubungula okuzinzileyo kwiinkqubo ze-TPU extrusion
- Uvakalelo lomphezulu oluhlengahlengiswayo ngokulawula idosi
- Ibhalansi ethile yesicelo phakathi kokucaca kunye nentuthuzelo
Ukusetyenziswa kweI-Si-TPV 3100-55A kwiinkqubo zokukhupha iifilimu eziqhumayoigxininisa amandla ayo njengesisombululo sokuguqula i-TPU sesizukulwana esilandelayo kwiifilimu eziguquguqukayo zonyango kunye nezemizi-mveliso.
Ngokudibanisaukusebenza kwe-soft-touch ethathwe kwi-silicone kunye nokuthembeka kwesakhiwo se-TPU, le nto ivumela abavelisi ukuba badlule ngaphaya kweendlela eziqhelekileyo zokutshintshiselana phakathi kokuthamba, ukuqina, kunye nokusebenziseka lula.
Njengoko uvavanyo lwabathengi luqhubeka lusanda kumacandelo eefilimu zonyango kunye nefilimu ezisebenza kakuhle, itekhnoloji ye-Si-TPV iyavela njengesixhobo esibalulekileyo sokwenza okuIinkqubo zefilimu ezithambileyo ze-elastomeric ezinamava omsebenzisi aphuculweyo kunye nokuthembeka kwemizi-mveliso.
