I-SILIKE Si-TPV 2150 Series yi-elastomer eguquguqukayo ye-silicone esekelwe kwi-vulcanizate, ephuhliswe ngokusebenzisa iteknoloji ehambelanayo. Le nkqubo isasaza irabha ye-silicone kwi-SEBS njengamasuntswana amahle, ukusuka kwi-1 ukuya kwi-3 microns phantsi kwe-microscope. Ezi zixhobo zodwa zidibanisa amandla, ukuqina, kunye nokuxhathisa kwe-abrasion ye-thermoplastic elastomers kunye neempawu ezinqwenelekayo ze-silicone, ezifana nokuthamba, ukuvakala kwesilika, kunye nokumelana nokukhanya kwe-UV kunye neekhemikhali. Ukongeza, izinto ze-Si-TPV ziyaphinda zisetyenziswe kwaye zingaphinda zisetyenziswe kwiinkqubo zokwenziwa kwemveli.
I-Si-TPV ingasetyenziselwa ngokuthe ngqo njengento ekrwada, eyenzelwe ngokukodwa ukusetyenziswa kwe-soft-touch over-molding kwi-electronics wearable, iimeko zokukhusela izixhobo zombane, izixhobo zemoto, ii-TPE eziphezulu, kunye namashishini ocingo lwe-TPE.
Ngaphaya kokusetyenziswa kwayo ngokuthe ngqo, i-Si-TPV inokuphinda isebenze njenge-polymer modifier kunye nenkqubo yokongeza i-elastomers ye-thermoplastic okanye ezinye iipolymers. Yongeza i-elasticity, iphucula ukusetyenzwa, kwaye yongeza iimpawu zomphezulu. Xa idityaniswe ne-TPE okanye i-TPU, i-Si-TPV ibonelela ngokugudiswa komphezulu okuhlala ixesha elide kunye nemvakalelo emnandi ye-tactile, ngelixa ikwaphucula umkrwelo kunye nokuxhathisa kwe-abrasion. Inciphisa ubulukhuni ngaphandle kokuchaphazela kakubi iipropati zoomatshini kwaye inika ukuguga okungcono, ukutyheli, kunye nokuchasana kwamabala. Inokwenza kwakhona ukugqitywa kwe-matte enqwenelekayo kumphezulu.
Ngokungafaniyo nezongezo ze-silicone eziqhelekileyo, i-Si-TPV inikezelwa kwifom ye-pellet kwaye iqhutywe njenge-thermoplastic. Isasaza kakuhle kwaye ngokulinganayo kuyo yonke i-polymer matrix, kunye ne-copolymer ibotshelelwa ngokwasemzimbeni kwi-matrix. Oku kuphelisa inkxalabo yokufuduka okanye "ukuqhakaza" imiba, ukwenza i-Si-TPV ibe sisisombululo esisebenzayo nesiyilayo sokuphumeza imiphezulu ethambileyo esilika kwi-thermoplastic elastomers okanye ezinye iipolymers. kwaye ayifuni ukuqhubekeka okongeziweyo okanye amanyathelo okwambathisa.
Uchungechunge lwe-Si-TPV 2150 luneempawu zexesha elide ezihambelana nolusu oluthambileyo, ukuchasana kakuhle kwamabala, akukho plasticizer kunye nesithambiso esongeziweyo, kwaye akukho mvula emva kokusetyenziswa kwexesha elide, esebenza njengeplasitiki kunye ne-polymer modifier, ngokukodwa ngokufanelekileyo. isetyenziselwa ukulungiselela i-silika emnandi yokuziva thermoplastic elastomers.
Ukuthelekisa iimpembelelo zeSi-TPV Plastic Additive kunye nePolymer Modifier kwi-TPE Performance
I-Si-TPV isebenza njengesiguquli sokuziva esidala kunye nesongezo sokusetyenzwa kwee-elastomer ze-thermoplastic kunye nezinye iipholima. Inokudityaniswa neelastomers ezahlukeneyo kunye nobunjineli okanye iiplastiki jikelele, ezifana TPE, TPU, SEBS, PP, PE, COPE, EVA, ABS, kunye PVC. Ezi zisombululo zinceda ekuphuculeni ukusebenza kakuhle kunye nokuphucula ukusebenza komkrwelo kunye ne-abrasion yamacandelo agqityiweyo.
Inzuzo ephambili yeemveliso ezenziwe nge-TPE kunye nee-Si-TPV ezixubeneyo kukuyilwa komphezulu othambileyo wesilika ongeyo-tacky-kanye amava abambekayo alindelwe ngabasebenzisi kwizinto abasoloko bezibamba okanye bezinxiba. Olu phawu lukhethekileyo lwandisa uluhlu lwezicelo ezinokuthi zibe kho kwimathiriyeli ye-TPE elastomer kuwo wonke amashishini amaninzi. Ngaphezu koko, ukubandakanya i-Si-TPV njengesilungisi kuphucula ukuguquguquka, ukuqina, kunye nokuqina kwemathiriyeli ye-elastomer, ngelixa ukwenza inkqubo yokuvelisa ingabizi kakhulu.
Uyasokola ukunyusa ukusebenza kwe-TPE? I-Si-TPV Izongezo zePlastiki kunye nezilungisi ze-polymer zibonelela ngeMpendulo
Intshayelelo kwii-TPEs
I-Thermoplastic elastomers (i-TPEs) ihlelwa ngokubunjwa kweekhemikhali, kubandakanywa i-Thermoplastic Olefins (TPE-O), i-Styrenic Compounds (TPE-S), i-Thermoplastic Vulcanizates (TPE-V), i-Polyurethanes (TPE-U), i-Copolyesters (COPE), kunye ne-Copolyamides (COPA). Ngelixa i-polyurethanes kunye ne-copolyesters zinokuthi zenziwe ngobunjineli obungaphezulu kwezinye izinto, iinketho ezingabizi kakhulu njenge-TPE-S kunye ne-TPE-V zihlala zibonelela ngokulunge ngakumbi kwizicelo.
Ii-TPE eziqhelekileyo ziyingxube yerubha kunye ne-thermoplastics, kodwa i-TPE-Vs iyahluka ngokuba namasuntswana erabha adityaniswe ngokuyinxenye okanye ngokupheleleyo, aphucula ukusebenza kwawo. I-TPE-Vs ibonisa iiseti zoxinzelelo oluphantsi, ukuxhathisa okungcono kweekhemikhali kunye nokukrazula, kunye nozinzo oluphezulu lobushushu, nto leyo eyenza ibe yinto efanelekileyo yokutshintsha irabha kwitywina. Ngokwahlukileyo, ii-TPE eziqhelekileyo zibonelela ngokuguquguquka okukhulu, ukomelela okuphezulu, ukuqina, kunye nombala, ukubenza bafanelekele iimveliso ezifana nempahla yabathengi, i-electronics, kunye nezixhobo zonyango. Bazibophelela kakuhle kwii-substrates eziqinileyo njenge-PC, i-ABS, i-HIPS, kunye neNylon, eluncedo kwizicelo zokuchukumisa okuthambileyo.
Imingeni ngeeTPEs
Ii-TPE zidibanisa ukuqina kunye namandla oomatshini kunye nokuqhubekeka, kuzenza ziguquguquke kakhulu. Iimpawu zabo ezinwebekayo, ezifana neseti yoxinzelelo kunye nobude, zivela kwisigaba se-elastomer, ngelixa amandla okuqina kunye nokukrazula kuxhomekeke kwinxalenye yeplastiki.
Ii-TPE zinokucutshungulwa njengesiqhelo se-thermoplastics kumaqondo obushushu aphakamileyo, apho zingena kwisigaba sokunyibilika, sivumela ukuveliswa okusebenzayo kusetyenziswa izixhobo ezisemgangathweni zokusetyenzwa kweplastiki. Uluhlu lwabo lobushushu bokusebenza lukwaphawuleka, ukusuka kumaqondo obushushu aphantsi kakhulu-kufutshane nendawo yokutshintsha kweglasi yesigaba se-elastomer-ukuya kumaqondo obushushu aphezulu asondele kwindawo yokunyibilika yenqanaba le-thermoplastic-eyongeza ukuguquguquka kwabo.
Nangona kunjalo, ngaphandle kwezi nzuzo, imiceli mngeni emininzi iyaqhubeka ekwandiseni ukusebenza kwee-TPEs. Omnye umba ophambili bubunzima bokulinganisa ukuqina kunye namandla omatshini. Ukuphucula ipropathi enye kudla ngokubakho ngexabiso lenye, nto leyo eyenza kube nzima kubavelisi ukuphuhlisa imixube yeTPE egcina ibhalansi engaguqukiyo yeempawu ezinqwenelekayo. Ukongeza, ii-TPE zisesichengeni sokonakala komphezulu onjengemikrwelo kunye nokutshatyalaliswa, okunokuthi kube nefuthe elibi kwinkangeleko kunye nokusebenza kweemveliso ezenziwe kwezi mathiriyeli.
