Nhanganyaya:
Munyika yezvigadzirwa zvesainzi uye mainjiniya, hutsva hunowanzo buda hunovimbisa kushandura maindasitiri nekugadzirisa zvakare nzira yatinosvika pakugadzira nekugadzira. Imwe hunyanzvi hwakadaro kusimudzira uye kutorwa kwesimba rinoita vulcanizate thermoplastic Silicone-based elastomer (kazhinji yakapfupikiswa kuSi-TPV), chinhu chakasiyana-siyana chine mukana wekutsiva yechinyakare TPE, TPU, uye silicone mumashandisirwo akasiyana siyana.
Si-TPV inopa nzvimbo ine yakasarudzika silky uye ganda-inoshamwaridzika kubata, yakanakisa tsvina yekuunganidza kuramba, nani kukwenya kuramba, haina plasticizer uye inopfavisa mafuta, isina kubuda ropa / inonamira njodzi, uye isina kunhuhwirira, izvo zvinoita kuti ive inoyevedza imwe nzira yeTPE, TPU, uye silicone mune akawanda mamiriro, kubva kune zvigadzirwa zvevatengi kuenda kumaindasitiri mashandisirwo.
Kuti uone kana Si-TPVs inogona kunyatso kutsiva TPE, TPU, uye silicone, isu tinofanirwa kuongorora hunhu hwadzo, maapplication, uye zvakanakira. Muchikamu chino, Tarisa kutanga Kunzwisisa Si-TPV uye TPE!
Kuenzanisa Kuongorora kweTPE & Si-TPV
1.TPE (Thermoplastic Elastomers):
TPEs ikirasi yezvinhu zvakasiyana-siyana zvinosanganisa zvimiro zve thermoplastics uye elastomers.
Ivo vanozivikanwa nekuchinjika kwavo, kusimba, uye nyore kugadzirisa.
TPEs dzinosanganisira akasiyana subtypes, akadai TPE-S (Styrenic), TPE-O (Olefinic), uye TPE-U (Urethane), imwe neimwe iine hunhu hwakasiyana.
2.Si-TPV (yakasimba vulcanizate thermoplastic Silicone-based elastomer):
Si-TPV inopinda mutsva mumusika we elastomer, inosanganisa mabhenefiti esilicone rabha uye thermoplastics.
Iyo inopa yakanakisa kuramba kupisa, UV mwaranzi, uye makemikari, Si-TPV inogona kugadziriswa uchishandisa yakajairwa thermoplastic nzira senge jekiseni kuumba uye extrusion.
Ndirini Inogona Si-TPV Alternative TPE?
1. High-Temperature Applications
Imwe yemabhenefiti ekutanga eSi-TPV pamusoro pemaTPE mazhinji ndeyekupokana kwayo kune tembiricha yepamusoro. MaTPE anogona kupfavisa kana kurasikirwa neayo elastic zvivakwa patembiricha yakakwira, ichidzikamisa kukodzera kwavo kwekushandisa uko kupikisa kupisa kwakakosha. Si-TPV kune rumwe rutivi, inochengetedza kushanduka kwayo uye kutendeseka kunyangwe pakupisa kwakanyanya, zvichiita kuti ive yakanakira kutsiva TPE mumashandisirwo akaita sezvikamu zvemotokari, zvibato zvekubikira, uye zvishandiso zvemaindasitiri zvinopisa.
2. Kemikari Resistance
Si-TPV inoratidza kuramba kwepamusoro kumakemikari, oiri, uye zvinonyungudutsa zvichienzaniswa nemhando dzakawanda dzeTPE. Izvi zvinoita kuti ive sarudzo yakakodzera yezvishandiso zvinoda kuratidzwa kune dzakaomarara makemikari nharaunda, sezvisimbiso, gaskets, uye hoses mumakemikari ekugadzira michina. TPEs inogona kusapa iyo yakafanana nhanho yekupikisa kwemakemikari mumamiriro ezvinhu akadaro.
3. Durability uye Weatherability
Mumamiriro ekunze uye akaomarara ezvakatipoteredza, Si-TPV inokunda TPEs maererano nekusimba uye kugona kwemamiriro ekunze. Kupokana kweSi-TPV kune UV mwaranzi uye mamiriro ekunze anoita kuti ive sarudzo yakavimbika kune zvekunze kunyorera, kusanganisira zvisimbiso uye gaskets mukuvaka, zvekurima, uye zvemugungwa. MaTPE anogona kudzikamisa kana kurasikirwa nemidziyo kana akafumurwa nechiedza chezuva chakareba uye zvakatipoteredza.
4. Biocompatibility
Kune zvekurapa uye zvehutano zvekushandisa, biocompatibility yakakosha. Nepo mamwe maumbirwo eTPE ari biocompatible, Si-TPV inopa yakasarudzika musanganiswa webiocompatibility uye yakasarudzika tembiricha kuramba, zvichiita kuti ive sarudzo inosarudzika yezvikamu zvakaita semachubhu ekurapa uye zvisimbiso zvinoda zvese zvivakwa.
5. Kudzokorora uye Kudzokorora
Si-TPV's thermoplastic nature inobvumira kudzokorora zvakare uye kudzokorora zvichienzaniswa neTPEs. Ichi chikamu chinowirirana nezvinangwa zvekusimudzira uye kuderedza marara, zvichiita kuti Si-TPV ive sarudzo inoyevedza yevagadziri vachivavarira kudzikisa nharaunda yavo.
Mhedziso:
Ingogara iri zano rakanaka kutsvagisa uye kuona yazvino musika unopa chigadzirwa Si-TPV paunenge uchitsvaga TPE !!
Kunyangwe TPEs dzakashandiswa zvakanyanya mumashandisirwo akasiyana siyana nekuda kwekusiyana-siyana kwavo. Nekudaro, kubuda kweSi-TPV kwakaunza imwe inogombedzera imwe nzira, kunyanya mumamiriro ezvinhu apo kupokana kwepamusoro-tembiricha, kuramba kwemakemikari, uye kusimba kwakakosha. Si-TPV yakasarudzika musanganiswa wezvivakwa inoita kuti ive mukwikwidzi akasimba kutsiva TPEs mumaindasitiri akati wandei, kubva kumotokari nemaindasitiri kusvika kune hutano uye zvekunze kunyorera. Sezvo tsvakiridzo nekusimudzira mune zvesainzi zvinhu zvichiramba zvichifambira mberi, basa reSi-TPV mukutsiva TPEs rinogona kuwedzera, richipa vanogadzira sarudzo dzakawanda dzekukwirisa zvigadzirwa zvavo kune zvinodiwa chaizvo.
