Chiyambi:
Mu dziko la sayansi ya zinthu ndi uinjiniya, nthawi zambiri pamabwera zatsopano zomwe zimalonjeza kusintha mafakitale ndikusintha momwe timayendera kapangidwe ndi kupanga. Chimodzi mwa zinthu zatsopanozi ndi kupanga ndi kugwiritsa ntchito dynamic vulcanizate thermoplastic Silicone-based elastomer (yomwe nthawi zambiri imafupikitsidwa kukhala Si-TPV), chinthu chosinthika chomwe chili ndi kuthekera kosintha TPE, TPU, ndi silicone yachikhalidwe m'magwiritsidwe osiyanasiyana.
Si-TPV imapereka malo okhala ndi silika wapadera komanso osavuta kugwiritsa ntchito pakhungu, kukana dothi bwino, kukana kukanda bwino, kulibe pulasitiki ndi mafuta ofewetsa, kulibe chiopsezo chotuluka magazi / kukana, komanso kusakhala ndi fungo loipa, zomwe zimapangitsa kuti ikhale njira ina yokongola m'malo mwa TPE, TPU, ndi silicone m'njira zambiri, kuyambira pazinthu zogula mpaka ntchito zamafakitale.
Kuti tidziwe nthawi yomwe ma Si-TPV angalowe m'malo mwa TPE, TPU, ndi silicone, tiyenera kuwona momwe amagwirira ntchito, momwe amagwiritsidwira ntchito, komanso zabwino zake. Munkhaniyi, yang'anani kaye Kumvetsetsa Si-TPV ndi TPE!
Kusanthula Koyerekeza kwa TPE ndi Si-TPV
1.TPE (Thermoplastic Elastomers):
Ma TPE ndi gulu la zipangizo zosiyanasiyana zomwe zimaphatikiza makhalidwe a thermoplastics ndi elastomers.
Amadziwika ndi kusinthasintha kwawo, kupirira, komanso kusinthasintha kwawo.
Ma TPE amaphatikizapo mitundu yosiyanasiyana, monga TPE-S (Styrenic), TPE-O (Olefinic), ndi TPE-U (Urethane), iliyonse ili ndi makhalidwe ake osiyana.
2.Si-TPV (dynamic vulcanizate thermoplastic Silicone-based elastomer):
Si-TPV ndi kampani yatsopano pamsika wa elastomer, yophatikiza ubwino wa rabara ya silicone ndi thermoplastics.
Imakhala yolimba kwambiri ku kutentha, kuwala kwa UV, ndi mankhwala, Si-TPV imatha kukonzedwa pogwiritsa ntchito njira zodziwika bwino za thermoplastic monga kupanga jakisoni ndi kutulutsa.
Kodi Si-TPV Alternative TPE ingagwiritsidwe ntchito liti?
1. Ntchito Zotentha Kwambiri
Chimodzi mwa zabwino zazikulu za Si-TPV kuposa ma TPE ambiri ndi kukana kwake kutentha kwambiri. Ma TPE amatha kufewetsa kapena kutaya mphamvu zawo zotanuka kutentha kwambiri, zomwe zimapangitsa kuti asamagwiritsidwe ntchito pamene kutentha kuli kofunika kwambiri. Koma Si-TPV imasunga kusinthasintha kwake komanso umphumphu wake ngakhale kutentha kwambiri, zomwe zimapangitsa kuti ikhale m'malo abwino kwambiri a TPE m'magwiritsidwe ntchito monga zida zamagalimoto, zogwirira zophikira, ndi zida zamafakitale zomwe zimatenthedwa.
2. Kukana Mankhwala
Si-TPV imaonetsa kukana kwambiri mankhwala, mafuta, ndi zosungunulira poyerekeza ndi mitundu yambiri ya TPE. Izi zimapangitsa kuti ikhale chisankho choyenera kugwiritsa ntchito zomwe zimafuna kuwonetsedwa m'malo ovuta a mankhwala, monga zomangira, ma gasket, ndi mapayipi m'zida zopangira mankhwala. TPE sizingapereke mulingo wofanana wa kukana mankhwala m'zochitika zotere.
3. Kulimba ndi Kusinthasintha kwa Nyengo
Mu nyengo yakunja komanso yovuta, Si-TPV imagwira ntchito bwino kuposa TPE pankhani yolimba komanso kuthekera kwa nyengo. Kukana kwa Si-TPV ku kuwala kwa UV ndi nyengo kumapangitsa kuti ikhale chisankho chodalirika chogwiritsidwa ntchito panja, kuphatikizapo zisindikizo ndi ma gaskets pantchito yomanga, ulimi, ndi zida zam'madzi. TPE zitha kuwonongeka kapena kutaya katundu wawo zikakumana ndi dzuwa kwa nthawi yayitali komanso zinthu zachilengedwe.
4. Kugwirizana kwa zamoyo
Pa ntchito zachipatala ndi zaumoyo, kugwirizana kwa zinthu zachilengedwe ndikofunikira. Ngakhale kuti mitundu ina ya TPE imagwirizana ndi zinthu zachilengedwe, Si-TPV imapereka kuphatikiza kwapadera kwa kugwirizana kwa zinthu zachilengedwe komanso kukana kutentha kwambiri, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri cha zinthu monga machubu azachipatala ndi zisindikizo zomwe zimafuna zinthu zonse ziwiri.
5. Kukonzanso ndi Kubwezeretsanso
Kapangidwe ka Si-TPV kokhala ndi kutentha kwa dzuwa kumathandiza kuti zinthu zikonzedwenso mosavuta komanso kubwezeretsedwanso zinthu mosavuta poyerekeza ndi TPE. Mbali imeneyi ikugwirizana ndi zolinga zokhazikika komanso imachepetsa kutayika kwa zinthu, zomwe zimapangitsa Si-TPV kukhala chisankho chokopa opanga omwe akufuna kuchepetsa kuwonongeka kwa chilengedwe.
Mapeto:
Nthawi zonse ndi bwino kufufuza ndikutsimikizira zomwe msika ukupereka pakali pano Si-TPV mukafuna TPE!!
Ngakhale kuti ma TPE akhala akugwiritsidwa ntchito kwambiri m'njira zosiyanasiyana chifukwa cha kusinthasintha kwawo. Komabe, kuonekera kwa Si-TPV kwabweretsa njira ina yabwino, makamaka m'malo omwe kukana kutentha kwambiri, kukana mankhwala, komanso kulimba ndikofunikira kwambiri. Kuphatikiza kwapadera kwa Si-TPV kumapangitsa kuti ikhale mpikisano wamphamvu wolowa m'malo mwa ma TPE m'mafakitale ambiri, kuyambira magalimoto ndi mafakitale mpaka ntchito zachipatala ndi zakunja. Pamene kafukufuku ndi chitukuko cha sayansi ya zinthu zikupitilira kupita patsogolo, udindo wa Si-TPV m'malo mwa ma TPE ukhoza kukula, kupatsa opanga zisankho zambiri kuti akonze zinthu zawo mogwirizana ndi zosowa zawo.
