Mankhwala a mndandanda wa Si-TPV
Zogulitsa za mndandanda wa Si-TPV zatulutsidwa ndi ma elastomer okhala ndi thermoplastic Silicone okhala ndi mphamvu ya vulcanizate ndi SILIKE,
Si-TPV ndi elastomer yapamwamba kwambiri ya thermoplastic vulcanizate thermoplastic silicone, yomwe imadziwikanso kuti silicone thermoplastic elastomer, yopangidwa ndi Chengdu SILIKE Technology Co., Ltd. Ili ndi tinthu ta rabara ta silicone tosungunuka bwino, kuyambira 1-3um, tomwe timafalikira mofanana mu resin ya thermoplastic kuti tipange kapangidwe kapadera ka chilumba. Mu kapangidwe kameneka, resin ya thermoplastic imagwira ntchito ngati gawo lopitilira, pomwe rabara ya silicone imagwira ntchito ngati gawo lofalikira. Si-TPV imagwira ntchito bwino kwambiri poyerekeza ndi rabara wamba wa thermoplastic vulcanized (TPV) ndipo nthawi zambiri imatchedwa 'Super TPV.'
Pakadali pano ndi chimodzi mwa zinthu zapadera komanso zatsopano padziko lonse lapansi zomwe siziwononga chilengedwe, ndipo zimatha kubweretsa zabwino kwa makasitomala kapena opanga zinthu monga kukhudza khungu, kukana kuvala, kukana kukanda, ndi zina zabwino zopikisana nazo.
Kuphatikiza kwa Si-TPV kwa makhalidwe ndi ubwino wa mphamvu, kulimba, ndi kukana kukwawa kwa elastomer iliyonse ya thermoplastic yokhala ndi makhalidwe abwino a mphira wa silicone wolumikizidwa bwino: kufewa, kumva ngati silika, kukana kuwala kwa UV ndi mankhwala, komanso kukongola kwapadera, koma mosiyana ndi ma vulcanizates achikhalidwe a thermoplastic, amatha kubwezeretsedwanso ndikugwiritsidwanso ntchito popanga zinthu.
Si-TPV yathu ili ndi zinthu zotsatirazi
≫Kukhudza khungu kwa nthawi yayitali komanso kofewa, sikufuna njira zina zowonjezera zokonzera kapena zophimba;
≫Chepetsani kuyamwa kwa fumbi, kumva kosagwedezeka komwe kumalimbana ndi dothi, kopanda pulasitiki ndi mafuta ofewetsa, kopanda mvula, kopanda fungo;
≫Ufulu umapaka utoto wokhazikika ndipo umapereka utoto wokhazikika, ngakhale utakhudzidwa ndi thukuta, mafuta, kuwala kwa UV, ndi kukwawa;
≫Yodzisunga yokha ku pulasitiki yolimba kuti ilole njira zapadera zopangira zinthu zambiri, zomangira mosavuta ku polycarbonate, ABS, PC/ABS, TPU, PA6, ndi zina zofanana ndi zimenezi, zopanda zomatira, komanso kuthekera kopanga zinthu zambiri;
≫Zingapangidwe pogwiritsa ntchito njira zodziwika bwino zopangira thermoplastic, pogwiritsa ntchito jekeseni/extrusion. Zoyenera kugwiritsidwa ntchito popangira jekeseni ya co-extrusion kapena jekeseni yamitundu iwiri. Zimagwirizana bwino ndi zomwe mukufuna ndipo zimapezeka ndi matte kapena gloss finishes;
≫Kukonza kwachiwiri kumatha kujambula mitundu yonse ya mapangidwe, ndikusindikiza pazenera, kusindikiza ma pad, ndikupaka utoto wopopera.
Kugwiritsa ntchito
Ma elastomer onse a Si-TPV amapereka mawonekedwe apadera obiriwira, otetezeka komanso osavuta kugwiritsa ntchito pogwira ndi manja, kuyambira ku Shore A 25 mpaka 90, olimba mtima, komanso ofewa kuposa ma elastomer a thermoplastic, zomwe zimapangitsa kuti akhale zinthu zabwino kwambiri zotetezera chilengedwe kuti ziwonjezere kukana kwa madontho, chitonthozo, komanso kukwanira kwa zida zamagetsi za 3C, zida zovalidwa, zida zamasewera, zinthu za ana aang'ono, zinthu za akuluakulu, zoseweretsa, zovala, zikwama zowonjezera, ndi nsapato, ndi zinthu zina zogulira.
Kuphatikiza apo, Si-TPV ngati chosinthira cha TPE ndi TPU, chomwe chingawonjezedwe ku TPE ndi TPU compounds kuti chiwongolere kusalala ndi kumva kukhudza, ndikuchepetsa kuuma popanda kuwononga mphamvu zamakanika, kukana ukalamba, kukana chikasu, ndi kukana banga.
