Kusiyana pakati pa ma caster a rabara a BR ndi ma caster a TPR

Kusiyana pakati pa rabara ya tpr ndi BR mumakampani opanga zinthu zopanga zinthu zosiyanasiyana ndi kwakukulu, kwa iwo omwe sanalumikizane ndi netiweki, n'kovuta kwambiri kusiyanitsa, lero kuchokera ku chiphunzitso chophatikizidwa ndi nkhaniyi, kuti abwenzi afotokoze mozama kusiyana pakati pa rabara ya tpr ndi BR.

tpr ndi chidule cha zinthu za Thermo-Plastic-Rubber, titha kuzitcha kuti zinthu za thermoplastic rabara. Ndi zinthu za thermoplastic zofewa za rabara zomwe zimakhala zotanuka popanda vulcanization, ndipo zimatha kukonzedwa ndikupangidwa mwachindunji (monga jekeseni, extrusion, blow molding, ndi zina zotero).

1, kugwiritsa ntchito kutentha kwa -45-90 ℃, nthawi zambiri zinthu za tpr zimachokera ku gawo lapansi la SBS, ndipo katundu wake wa mankhwala ndi awa: kukana kwa marble, kukana ukalamba, kukana kutentha kwa 70-75 ℃. Ngati mukufuna zinthu zabwino zokana ukalamba, mutha kusankha zinthu zoyambira za SEBS zomwe zasinthidwa.

2, Kulimba kwa rabara ya BR komanso kukana kukwawa, kukana kutsetsereka ndi kugwedezeka ndikwabwino kwambiri, zinthu za tpr ndizofewa komanso zomasuka kuposa rabara, koma mphamvu yokoka, kukana kutopa komanso mphamvu zamakanika sizofanana ndi rabara yovunda.

3, makhalidwe a chilengedwe, tpr zipangizo monga mphira wofewa wochezeka ndi chilengedwe, zinthu zoopsa zazikulu monga plasticizers phthalates Phthalate, nonylphenol NP, PAHs Kuzindikira PAHs, mogwirizana ndi miyezo yoyesera chitetezo cha chilengedwe ya ROHS, REACH, EN71-3, ASTMF963.

4, makhalidwe a kuuma, zinthu za tpr zitha kusinthidwa mu kuuma kwa gombe madigiri 5-100 a kuuma kwake, zinthu zosinthidwa zochokera ku SEBS zitha kusinthidwa kukhala kuuma kotsika.

Rabala ya BR ndi chinthu cholimba kwambiri cha polima chokhala ndi kusintha kosinthika, cholimba kutentha kwa chipinda, chingapangitse kusintha kwakukulu pogwiritsa ntchito mphamvu yaying'ono yakunja, ndipo chingabwezeretse momwe chinalili poyamba mutachotsa mphamvu yakunja. Rabala ndi ya polima yopanda mawonekedwe, kutentha kwake kwagalasi (T g) ndi kochepa, kulemera kwa mamolekyu nthawi zambiri kumakhala kwakukulu kwambiri, kuposa mazana zikwi.

Onani kusiyana pakati pa ma caster a TPR ndi ma caster a rabara:

Pali zinthu zambiri zopangira pamwamba pa mawilo a ma casters, monga ma casters a TPU, ma casters a PP, ma casters a TPR, ma casters a PU, ma casters a TPE, ma casters a nayiloni, ma casters a rabara ndi zina zotero.

1, ma casters a rabara a BR ndi ofewa komanso opanda phokoso kuposa ma casters a TPR.

2, poyerekeza ndi mtengo, mphira sungabwezeretsedwe, TPR ikhoza kubwezeretsedwedwanso, TPR casters ndi yotsika mtengo kuposa BR rabara casters.

4, poganizira za kuteteza chilengedwe, TPR ndi chinthu chatsopano choteteza chilengedwe, mphira wa BR siwoteteza chilengedwe.
