Kodi pali kusiyana kotani pakati pa ma casters a TPR ndi oponya mphira?

Monga chigawo chofunikira cha zipangizo zosiyanasiyana, mipando ndi zipangizo, zinthu ndi ntchito za casters zimakhudza kwambiri ubwino ndi ntchito ya mankhwala onse. Mwa mitundu yambiri ya ma casters, ma casters a TPR ndi ma BR rabara casters ndi zisankho ziwiri zofala. Lero padzakhala kufananitsa mwatsatanetsatane kusiyana pakati pa mitundu iwiriyi ya BR vs. tpr casters.

Zida ndi Katundu
Choyamba, ma casters a TPR amapangidwa ndi mphira wa thermoplastic (TPR), chinthu cha thermoplastic chokhala ndi elasticity ya rabara, chomwe sichiyenera kutenthedwa ndipo chimakhala chogwirizana ndi chilengedwe, chosakhala ndi poizoni, komanso chamitundu yowala. Chifukwa cha kulimba komanso kukana kwa abrasion kwa zinthu za TPR, ma casters a TPR nthawi zambiri amakhala ndi ma abrasion abwino, mafuta ndi nyengo.
Mosiyana, mphira wa BR amapangidwa kuchokera ku mphira wa butadiene (BR), mphira wopangidwa kuchokera ku polymerization ya butadiene monomers, yomwe mamolekyu ake amafanana ndi mphira wachilengedwe. mphira wa BR uli ndi kukhuthala kwabwino, kukana kwa abrasion, kukana kuzizira, komanso flex resistance.

Processing ndi ntchito
Magwiridwe azinthu za TPR ndizabwinoko kuposa mphira, ndipo amatha kusinthidwa ndi zida wamba zopangira thermoplastic popanda chithandizo chapadera cha vulcanization. Izi zimapangitsa kuti ma casters a TPR agwire bwino ntchito komanso otsika mtengo kupanga.
Komabe, makina opangira mphira a BR amapambana pakuchita bwino kwambiri, makamaka pa kutentha kwakukulu. Labala ya BR imakhala ndi kukana kwambiri kwa abrasion, kukana kuphulika, komanso kukana misozi yamphamvu, yomwe imalola oponya mphira a BR kukhalabe ndi ntchito yabwino m'malo ovuta.

Chitetezo ndi chitetezo cha chilengedwe
Pankhani yachitetezo cha chilengedwe, zinthu za TPR zili ndi mwayi: TPR ndi zinthu zoteteza zachilengedwe komanso zopanda poizoni zomwe zimagwirizana ndi ROHS, REACH ndi miyezo ina yachilengedwe, ndipo zitha kugwiritsidwa ntchito kwambiri pazida zamankhwala, zoseweretsa za ana ndi magawo ena. Mosiyana ndi izi, ngakhale mphira wa BR ndiwothandizanso ndi chilengedwe, ukhoza kukhala woletsedwa ndi malamulo a chilengedwe pazantchito zina.

Posankha ma casters, kuganizira mozama kuyenera kukhazikitsidwa pazifukwa monga zochitika zinazake zogwiritsira ntchito, zofunikira zogwirira ntchito ndi malamulo a chilengedwe. Mwachitsanzo, ma casters a TPR akhoza kukhala chisankho chabwino pazochitika zomwe zimafuna zokolola zambiri, zotsika mtengo komanso zofunikira za chilengedwe, pamene BR rabara ya BR ikhoza kukhala yoyenera kwambiri pazochitika zogwiritsira ntchito zomwe zimafuna kuchitapo kanthu kwakukulu ndi kukana kutentha kwakukulu.
