Kusiyanitsa pakati pa tpr ndi BR rabara mu makampani opangira caster ndizochitika zonse, kwa iwo omwe sanakumanepo ndi intaneti ndizovuta kwambiri kusiyanitsa, lero kuchokera ku chiphunzitsocho pamodzi ndi mlandu, kuti abwenzi awononge kusiyana pakati pawo. tpr ndi BR rabara mozama.
tpr ndiye chidule cha zinthu za Thermo-Plastic-Rubber, titha kuzitcha ngati zida za mphira wa thermoplastic. Ndi thermoplastic zofewa mphira zinthu ndi elasticity popanda vulcanization, ndipo akhoza kukonzedwa mwachindunji ndi kuumbidwa (monga jekeseni akamaumba, extrusion, kuwomba akamaumba, etc.).
1, ntchito kutentha osiyanasiyana -45-90 ℃, kawirikawiri anati tpr zakuthupi zachokera SBS gawo lapansi, katundu wake mankhwala ndi motere: nsangalabwi kukana, kukalamba kukana ambiri, kutentha kukana 70-75 ℃. Ngati mukufuna zida zabwino zokana kutentha kukalamba, mutha kusankha zida zosinthidwa za SEBS.
2, kulimba kwa mphira wa BR ndi kukana kwabwino kwa abrasion, anti-slip and shock absorption performance ndiyabwino kwambiri, zinthu za tpr zofewa komanso zomasuka kukhala zapamwamba kuposa mphira, koma mphamvu zolimba zakuthupi, kukana kutopa komanso makina amakina sizabwino ngati mphira wowombedwa.
3, mawonekedwe a chilengedwe, zinthu za tpr monga mphira wofewa wokonda zachilengedwe, zinthu zazikulu zowopsa monga mapulasitiki phthalates Phthalate, nonylphenol NP, PAHs PAHs kuzindikira, mogwirizana ndi ROHS, REACH, EN71-3, ASTMF963 miyezo yoyesera zachilengedwe.
4, mawonekedwe a kuuma, zinthu za tpr zitha kusinthidwa mu kuuma kwa Shore 5-100 madigiri a kuuma kwake, zida zosinthidwa za SEBS zitha kusinthidwa kukhala kuuma kochepa.
BR rabara ndi zinthu zotanuka kwambiri za polima zokhala ndi mapindikidwe osinthika, zotanuka kutentha kwachipinda, zimatha kutulutsa mapindikidwe akulu mothandizidwa ndi mphamvu yaying'ono yakunja, ndipo zimatha kubwezeretsa chikhalidwe choyambirira pambuyo pochotsa mphamvu yakunja. Mphira ndi wa polima kwathunthu amorphous, galasi kutentha ake kusintha (T g) ndi otsika, molekyulu kulemera nthawi zambiri lalikulu, oposa mazana zikwi.
Onani kusiyana pakati pa ma casters a TPR ndi oponya mphira:
Pali zida zambiri zama gudumu pamwamba pa ma casters, monga ma casters a TPU, PP casters, ma TPR casters, PU casters, TPE casters, casters nayiloni, oponya mphira ndi zina zotero.
1, zoponya mphira za BR ndizofewa komanso zabata kuposa zoponya za TPR.
2, poyerekeza ndi mtengo wake, mphira sungathe kubwezeretsedwanso, TPR ikhoza kubwezeretsedwanso, makina opangira mphira a TPR amawononga ndalama zochepa kuposa zopangira mphira za BR.
4, pakuwona chitetezo cha chilengedwe, TPR ndi chinthu chatsopano chokonda zachilengedwe, mphira wa BR siwokonda zachilengedwe.
