I-SILIKE Si-TPV 2150 Series iyi-elastomer esekwe ku-vulcanizate enamandla, ethuthukiswe kusetshenziswa ubuchwepheshe obusezingeni eliphezulu bokuhambisana. Le nqubo ihlakaza irabha ye-silicone ku-SEBS njengezinhlayiya ezinhle, ezisukela kuma-microns angu-1 kuye kwangu-3 ngaphansi kwesibonakhulu. Lezi zinto ezihlukile zihlanganisa amandla, ukuqina, kanye nokumelana nokuhuzuka kwama-thermoplastic elastomer nezinto ezifiselekayo ze-silicone, njengokuthambile, ukuzwakala kwesilika, nokumelana nokukhanya kwe-UV namakhemikhali. Ukwengeza, izinto ze-Si-TPV ziyasebenziseka kabusha futhi zingasetshenziswa kabusha ezinqubweni zokukhiqiza ezingokwesiko.
I-Si-TPV ingasetshenziswa ngokuqondile njengempahla eluhlaza, eklanyelwe ngokukhethekile izinhlelo zokusebenza zokubumba ezithinta kancane kuzinto zikagesi ezigqokekayo, amakesi okuvikela emishini kagesi, izakhi zezimoto, ama-TPE asezingeni eliphezulu, nezimboni zezintambo ze-TPE.
Ngaphandle kokusetshenziswa kwayo okuqondile, i-Si-TPV ingasebenza futhi njengesilungisi se-polymer futhi icubungule isengezo sama-thermoplastic elastomers noma amanye ama-polymer. Ithuthukisa ukunwebeka, ithuthukise ukucutshungulwa, futhi ikhulise izakhiwo ezingaphezulu. Uma ihlanganiswe ne-TPE noma i-TPU, i-Si-TPV ihlinzeka ngobushelelezi bendawo obuhlala isikhathi eside kanye nomuzwa omnandi wokuthinta, kuyilapho ithuthukisa ukumelana nokuklwebheka nokuhuzuka. Yehlisa ubulukhuni ngaphandle kokuthinta kabi izakhiwo zemishini futhi inikeza ukuguga okungcono, ukuphuzi, nokumelana namabala. Ingase futhi idale isiphetho se-matte esifiselekayo ebusweni.
Ngokungafani nezithako ezijwayelekile ze-silicone, i-Si-TPV inikezwa ngefomu le-pellet futhi icutshungulwa njenge-thermoplastic. Ihlakazeka kahle futhi ngokulinganayo kuyo yonke i-polymer matrix, ne-copolymer iboshwa ngokomzimba ku-matrix. Lokhu kususa ukukhathazeka kokufuduka noma izindaba "eziqhakazayo", okwenza i-Si-TPV ibe yisixazululo esisebenzayo nesisha sokuzuza izindawo ezithambile ezinosilika kuma-thermoplastic elastomers noma amanye ama-polymer. futhi ayidingi izinyathelo ezengeziwe zokucubungula noma zokumboza.
Uchungechunge lwe-Si-TPV 2150 lunezici zokuthintwa okuthambile okuvumelana nesikhumba isikhathi eside, ukumelana kahle namabala, akukho plasticizer nesithambile esingeziwe, futhi akukho mvula ngemva kokusetshenziswa isikhathi eside, esisebenza njengesengezo sepulasitiki nesilungisi se-polymer, ikakhulukazi ngokufanelekile. isetshenziselwa ukulungiswa kwe-lastomers ye-thermoplastic ejabulisayo.
Ukuqhathanisa imiphumela ye-Si-TPV Plastic Additive kanye ne-Polymer Modifier ekusebenzeni kwe-TPE
I-Si-TPV isebenza njengesiguquli sokuzizwa esisha kanye nesithasiselo sokucubungula sama-thermoplastic elastomers namanye ama-polymer. Ingahlanganiswa nama-elastomer ahlukahlukene nobunjiniyela noma amapulasitiki ajwayelekile, njenge-TPE, i-TPU, i-SEBS, i-PP, i-PE, i-COPE, i-EVA, i-ABS, ne-PVC. Lezi zixazululo zisiza ukuthuthukisa ukusebenza kahle kokucubungula futhi zithuthukise ukusebenza kokumelana nokuklwebheka nokuhuzuka kwezingxenye eziqediwe.
Inzuzo eyinhloko yemikhiqizo eyenziwe ngezingxube ze-TPE kanye ne-Si-TPV wukwakhiwa kwendawo ethambile-ethambile engena-tacky—ngokunembile umuzwa othintekayo olindelwe abasebenzisi bokugcina ezintweni abavame ukuzithinta noma abazigqokayo. Lesi sici esiyingqayizivele sandisa ububanzi bezinhlelo zokusebenza ezingaba khona ze-TPE elastomer materials kuzo zonke izimboni eziningi. Ngaphezu kwalokho, ukufaka i-Si-TPV njengesilungisi kuthuthukisa ukuguquguquka, ukunwebeka, nokuqina kwezinto ze-elastomer, kuyilapho kwenza inqubo yokukhiqiza ingabizi kakhulu.
Uzabalaza Ukuthuthukisa Ukusebenza Kwe-TPE? Izithasiselo zePlastiki ze-Si-TPV nezilungisi ze-polymer Zihlinzeka Ngempendulo
Isingeniso kuma-TPE
Ama-Thermoplastic elastomers (TPEs) ahlukaniswa ngokwakhiwa kwamakhemikhali, okuhlanganisa i-Thermoplastic Olefins (TPE-O), Styrenic Compounds (TPE-S), Thermoplastic Vulcanizates (TPE-V), Polyurethanes (TPE-U), Copolyesters (COPE), kanye neCopolyamides. (COPA). Nakuba ama-polyurethanes nama-copolyester angase enziwe ngobunjiniyela ngokweqile ukuze busetshenziswe okuthile, izinketho ezingabizi kakhulu njenge-TPE-S ne-TPE-V ngokuvamile zinikeza ukulingana okungcono kwezinhlelo zokusebenza.
Ama-TPE avamile ayingxube ebonakalayo yerabha ne-thermoplastics, kodwa ama-TPE-V ahluka ngokuba nezinhlayiya zenjoloba ezixhumene ngokwengxenye noma ngokugcwele, ezithuthukisa ukusebenza kwazo. Ama-TPE-V afaka amasethi okucindezela aphansi, ukumelana okungcono kwamakhemikhali nokuhuzuka, nokuzinza okuphezulu kwezinga lokushisa, okuwenza alungele ukufaka esikhundleni senjoloba ezimpawini. Ngokuphambene, ama-TPE avamile ahlinzeka ngokuguquguquka okukhulu kokwakheka, amandla aphezulu okuqina, ukunwebeka, nokubabala, okuwenza afanelekele imikhiqizo efana nempahla yabathengi, izinto zikagesi, namadivayisi ezokwelapha. Baphinde bahlangane kahle nama-substrates aqinile njenge-PC, i-ABS, i-HIPS, neNyiloni, enenzuzo ezinhlelweni zokuthinta okuthambile.
Izinselele ngama-TPE
Ama-TPE ahlanganisa ukunwebeka namandla emishini kanye nokucutshungulwa, okuwenza abe nezinto ezihlukahlukene kakhulu. Izici zabo ezinwebekayo, njengesethi yokucindezelwa kanye nokwelula, zivela esigabeni se-elastomer, kuyilapho amandla okuqina nawokudabuka ancike engxenyeni yepulasitiki.
Ama-TPE angacutshungulwa njengama-thermoplastics avamile emazingeni okushisa aphakeme, lapho angena khona esigabeni sokuncibilika, okuvumela ukukhiqizwa okuphumelelayo kusetshenziswa imishini evamile yokucubungula ipulasitiki. Ibanga labo lokushisa elisebenzayo liyaphawuleka, lisuka emazingeni okushisa aphansi kakhulu—eduze nendawo yokushintsha ingilazi yesigaba se-elastomer—kuya emazingeni okushisa aphakeme aseduze nendawo yokuncibilika yesigaba se-thermoplastic—okwenezela ekusebenzisaneni kwezinto ezihlukahlukene.
Kodwa-ke, ngaphandle kwalezi zinzuzo, izinselele ezimbalwa ziyaqhubeka nokwenza ngcono ukusebenza kwama-TPE. Inkinga eyodwa enkulu wubunzima bokulinganisa ukunwebeka namandla emishini. Ukuthuthukisa isakhiwo esisodwa kuvame ukufika ngezindleko zesinye, okwenza kube inselele kubakhiqizi ukuthi bakhe ukwakheka kwe-TPE okugcina ibhalansi engashintshi yezici ezifiswayo. Ukwengeza, ama-TPE asengozini yokulimala endaweni efana nokuklwebheka nokuma, okungaba nomthelela omubi kokubili ukubukeka nokusebenza kwemikhiqizo eyenziwe ngalezi zinto.
