Chiyambi:
M'dziko la sayansi ya zida ndi uinjiniya, zatsopano nthawi zambiri zimatuluka zomwe zimalonjeza kusintha mafakitale ndikukonzanso momwe timayendera mamangidwe ndi kupanga.Chimodzi mwazinthu zatsopanozi ndikupanga ndi kutengera vulcanizate thermoplastic Silicone-based elastomer (yofupikitsidwa kukhala Si-TPV), chinthu chosunthika chomwe chili ndi kuthekera kolowa m'malo mwa TPE, TPU, ndi silikoni yachikhalidwe m'magwiritsidwe osiyanasiyana.
Si-TPV imapereka mawonekedwe owoneka bwino komanso owoneka bwino pakhungu, kukana bwino kusonkhanitsa zinyalala, kukana kukanda bwino, ilibe pulasitiki ndi mafuta ofewetsa, osataya magazi / chiwopsezo chomata, komanso osanunkhiza, zomwe zimapangitsa kuti ikhale njira yowoneka bwino. TPE, TPU, ndi silikoni m'mawonekedwe ambiri, kuchokera kuzinthu zogula mpaka kumafakitale.
Kuti tidziwe nthawi yomwe Si-TPVs ingalowe m'malo mwa TPE, TPU, ndi silikoni, tiyenera kuyang'ana zomwe zili, ntchito, ndi ubwino wake.M'nkhaniyi, Yang'anani poyamba Kumvetsetsa Si-TPV ndi TPE!
Kuwunika Koyerekeza kwa TPE & Si-TPV
1.TPE (Thermoplastic Elastomers):
Ma TPE ndi gulu lazinthu zosunthika zomwe zimaphatikiza zinthu za thermoplastics ndi elastomers.
Amadziwika ndi kusinthasintha kwawo, kulimba mtima, komanso kumasuka pokonza.
TPEs zikuphatikizapo subtypes zosiyanasiyana, monga TPE-S (Styrenic), TPE-O (Olefinic), ndi TPE-U (Urethane), aliyense ndi katundu osiyana.
2.Si-TPV ( dynamic vulcanizate thermoplastic Silicone-based elastomer ):
Si-TPV ndiwolowa kumene mumsika wa elastomer, kuphatikiza zabwino za mphira wa silicone ndi thermoplastics.
Imapereka kukana kwambiri kutentha, kuwala kwa UV, ndi mankhwala, Si-TPV imatha kukonzedwa pogwiritsa ntchito njira zodziwika bwino za thermoplastic monga kuumba jekeseni ndi kutulutsa.
Kodi Si-TPV Alternative TPE Ingathe Liti?
1. Mapulogalamu Otentha Kwambiri
Chimodzi mwazabwino zazikulu za Si-TPV kuposa ma TPE ambiri ndikukana kwake kutentha kwambiri.Ma TPE amatha kufewetsa kapena kutaya mphamvu zawo zotanuka pakutentha kokwera, ndikuchepetsa kukwanira kwawo pakugwiritsa ntchito pomwe kutentha kuli kofunikira.Si-TPV kumbali ina, imasunga kusinthasintha kwake komanso kukhulupirika kwake ngakhale kutentha kwambiri, kupangitsa kuti ikhale yabwino m'malo mwa TPE muzogwiritsa ntchito ngati zida zamagalimoto, zogwirira zophikira, ndi zida zamafakitale zomwe zimatenthedwa.
2. Kukana kwa Chemical
Si-TPV imawonetsa kukana kwakukulu kwa mankhwala, mafuta, ndi zosungunulira poyerekeza ndi mitundu yambiri ya TPE.Izi zimapangitsa kukhala chisankho choyenera pazogwiritsa ntchito zomwe zimafunikira kukhudzidwa ndi malo ovuta amankhwala, monga zisindikizo, ma gaskets, ndi ma hoses mu zida zopangira mankhwala.Ma TPE sangapereke mulingo womwewo wa kukana kwa mankhwala muzochitika zotere.
3. Kukhalitsa ndi Weatherability
M'malo akunja komanso ovuta zachilengedwe, Si-TPV imachita bwino kuposa ma TPE potengera kulimba komanso kuthekera kwanyengo.Kukana kwa Si-TPV ku radiation ya UV ndi nyengo kumapangitsa kukhala chisankho chodalirika pazogwiritsa ntchito zakunja, kuphatikiza zisindikizo ndi ma gaskets pomanga, ulimi, ndi zida zam'madzi.Ma TPE amatha kunyozetsa kapena kutaya katundu wawo akakhala ndi kuwala kwa dzuwa kwa nthawi yayitali komanso zachilengedwe.
4. Biocompatibility
Pazofunsira zamankhwala ndi zaumoyo, biocompatibility ndiyofunikira.Ngakhale mapangidwe ena a TPE ndi ogwirizana ndi biocompatible, Si-TPV imapereka kuphatikiza kwapadera kwa biocompatibility ndi kukana kutentha kwapadera, kupangitsa kukhala chisankho chokondedwa pazinthu monga machubu azachipatala ndi zosindikizira zomwe zimafunikira zonse ziwiri.
5. Kukonzanso ndi Kubwezeretsanso
Si-TPV's thermoplastic nature imalola kukonzanso kosavuta ndikubwezeretsanso poyerekeza ndi ma TPE.Izi zimagwirizana ndi zolinga zokhazikika ndikuchepetsa zinyalala zakuthupi, kupangitsa Si-TPV kukhala chisankho chokongola kwa opanga omwe akufuna kuchepetsa malo awo achilengedwe.
Pomaliza:
Ndibwino nthawi zonse kufufuza ndikutsimikizira zomwe msika ukupereka Si-TPV mukafuna TPE!!
Ngakhale ma TPE akhala akugwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana chifukwa cha kusinthasintha kwawo.Komabe, kutuluka kwa Si-TPV kwabweretsa njira ina yolimbikitsira, makamaka m'malo omwe kukana kutentha kwambiri, kukana kwamankhwala, komanso kulimba ndikofunikira.Kuphatikizika kwapadera kwa Si-TPV kumapangitsa kuti pakhale mpikisano wamphamvu wolowa m'malo mwa TPE m'mafakitale ambiri, kuyambira zamagalimoto ndi mafakitale kupita ku zaumoyo ndi ntchito zakunja.Pamene kafukufuku ndi chitukuko mu sayansi ya zinthu zikupitilirabe, ntchito ya Si-TPV m'malo mwa ma TPE ikuyenera kukulirakulira, kupatsa opanga zisankho zambiri kuti akwaniritse zosowa zawo.
