Musiyano uye Hunhu hwe TPU, Rubha uye Silicone
tsananguro
TPU Tsanangudzo:
TPU imhando ye thermoplastic elastomer (TPE), izvo zvinomirira thermoplastic polyurethane elastomer. Inoenderana nemhoteredzo, haina chepfu, uye inogona kushandiswazve. TPU ine yakanakisa kupfeka kusagadzikana, elasticity, uye mafuta kuramba. Kuoma kwayo kunobva pa70A kusvika 98A, uye ruvara rwayo rwekutanga rwuri pachena.
Rubber Tsanangudzo:
Rubber inogona kukamurwa kuita rabha rechisikigo uye rekugadzira rabha zvichienderana neyakagadzirwa zvinhu. Rabha yechisikigo inotorwa kubva mumiti yerabha, ukuwo synthetic rubber inogadzirwa zvine hunyanzvi. Rubber ine marudzi akasiyana uye madhigirii ekuramba kupfeka. Rubber is amorphous polymer yakakwana, inova elastic patembiricha yekamuri uye inogona kuburitsa hombe deformation pasi pesimba diki rekunze. Mushure mekubvisa simba rekunze, rinogona kudzoreredza chimiro chayo chepakutanga.
Silicone Tsanangudzo:
Silicone chinhu chakanyanya kushanda adsorbent zvinhu zvine hushamwari zvakatipoteredza, zvisina chepfu, uye zvisinganhuhwi. Iyo ine yakakwira adsorption performance, haina kunyungudika mumvura, ine yakanaka yekudziya kugadzikana uye kugadzikana kwemakemikari, uye ine yakakwirira mechanical simba.
Kusiyana uye Hunhu:
Kunzwa kwesilicone kwakapfava, uye elasticity yayo haina kunaka senge TPU. Inonzwa inonamira uye iri nyore kukwezva huruva, zvichiita kuti zviome kuchenesa. Kufema kwayo hakuna kusimba se TPU, uye kana yakashandiswa kugadzira makesi efoni uye mamwe emagetsi ekudzivirira zvigadzirwa zvemagetsi, zvinogona kukonzera kuderera kwekupisa kwefoni. Silicone inewo yakashata pakuti kuramba kwayo kubvarura kwakashata uye kusimba kwayo kwakadzikira. Chakanakira chete ndechekuti yakachipa kupfuura TPU. TPU makesi enhare dzemidziyo uye zvivharo zvekudzivirira zvinokunda kushomeka kwemakesi efoni yesilicone, neakanaka kupfeka kuramba, kukwenya kuramba, kukanganisa kwemaitiro, kubatwa nekuvhunduka, uye elasticity. TPU makesi efoni ane yakaoma uye akasununguka kunzwa, usapera foni, usakwezve guruva, uye uri nyore kuchenesa, uchiita kuti ive yakakurumbira pakati pevatengi nevagadziri. Mukuenzanisa nerabha, TPU ine mabhenefiti ari pachena mukuramba kupfeka, simba remuchina, elasticity, uye kusimba kwekudzikira kwakadzika, kunyangwe imwe rabha isingapfeki iine kusakara kurinani. TPU ine yakanaka yakadzika-tembiricha kuramba uye inogona kuramba iine elasticity yakanakisa uye kusimba pa -50 ℃, nepo rabha haigone uye inoita brittle uye nyore kutyora. Parizvino, zvigadzirwa zvakawanda pamusika zvinogadzirwa nerabha kunyanya nekuti yakachipa uye yakaderera-mutengo. Saizvozvo, TPU zvinhu zvinogona kutsiva rabha mukuita kwakawanda. Mune ramangwana, TPU ichave imwe yezvinonyanya kufarirwa zvigadzirwa zvekugadzira.
Ungasiyanisa sei?
Saka, mukugadzira uye kushandiswa, tinosiyanisa sei pakati TPU, rabha, uye silicone? Tinogona kusiyanisa zvinhu zvitatu izvi zvakanaka kuburikidza nekupisa, kunhuwa, kuoma, nezvimwe.
TPU (thermoplastic polyurethane):
Murazvo unopfuta weyero, une kakupenya zvishoma uye zvinoputika; ine kunhuhwirira kwakakosha (kunhuhwirira kweammonia); TPU zvidimbu zvinoonekera, uye zvinogonawo kuenzaniswa nechena kana nhema. Hukukutu hwemhando ndeye 60A ~ 80D.
Rubber (vulcanized type):
Murazvo unopfuta weyero, uye kunhuhwirira kwakakura (kunhuhwirira hydrocarbons, vulcanizing agents, anti-aging agents uye zvimwe zvinowedzera zvinopisa kugadzira); vulcanized rabha zvigadzirwa zvinowanzova zvitema, asiwo mukaka chena kana yero zvigadzirwa; kuoma kwezvinhu zvinowanzoita 50 ~ 80A. Zvigadzirwa zverabha zvine kusimba kwakanyanya.
Silicone:
Murazvo unopfuta wakachena chena, nekunhuhwirira kwakareruka, utsi hushoma, uye zvakasara zvichena upfu; silicone ine mavara akajeka, pamwe chete nezvimwe zvinhu zvisina kusimba zvakasimba; yakakamurwa kuva inorganic uye organic silicone; kuoma chiyero ndeye 10 ~ 90A. Silicone ine yakanakisa tensile kusimba.
