Kodi kusiyana pakati pa ma TPR casters ndi ma rabara casters ndi kotani?

Monga gawo lofunika kwambiri la zida zosiyanasiyana, mipando ndi zida, zipangizo ndi magwiridwe antchito a ma casters zimakhudza kwambiri ubwino ndi magwiridwe antchito a chinthu chonsecho. Pakati pa mitundu yambiri ya ma casters, ma casters a TPR ndi ma casters a rabara a BR ndi zosankha ziwiri zomwe zimafala. Lero tikambirana mwatsatanetsatane kusiyana pakati pa mitundu iwiriyi ya ma casters a BR ndi tpr.

Zipangizo ndi Katundu
Choyamba, ma casters a TPR amapangidwa ndi rabara ya thermoplastic (TPR), yomwe ndi thermoplastic yokhala ndi kusinthasintha kwa rabara, yomwe siifunika kusungunuka ndipo ndi yoteteza chilengedwe, yopanda poizoni, komanso yowala. Chifukwa cha kusinthasintha ndi kukana kwa zinthu za TPR, ma casters a TPR nthawi zambiri amakhala ndi kukana bwino kwa kukanda, mafuta ndi nyengo.
Mosiyana ndi zimenezi, ma BR rabara casters amapangidwa ndi butadiene rabara (BR), rabara yopangidwa ndi polymerization ya butadiene monomers, yomwe kapangidwe kake ka molekyulu kamafanana ndi ka rabara wachilengedwe. BR rabara ili ndi kusinthasintha kwabwino, kukana kukwawa, kukana kuzizira, komanso kukana kusinthasintha.

Kukonza ndi magwiridwe antchito
Kagwiridwe ka ntchito ka zinthu za TPR ndi kabwino kuposa ka rabala, ndipo kangathe kukonzedwa ndi zipangizo wamba zogwiritsira ntchito thermoplastic popanda mankhwala apadera a vulcanization. Izi zimapangitsa kuti ma casters a TPR akhale ogwira ntchito bwino komanso otchipa kupanga.
Komabe, ma casters a rabara a BR amachita bwino kwambiri pakugwira ntchito mosinthasintha, makamaka kutentha kwambiri. Rabara ya BR ili ndi kukana kwabwino kwambiri kwa kukwawa, kukana kubowoka, komanso kukana misozi mosinthasintha, zomwe zimathandiza ma casters a rabara a BR kukhalabe ndi ntchito yabwino m'malo ovuta.

Chitetezo ndi chitetezo cha chilengedwe
Ponena za kuteteza chilengedwe, zinthu za TPR zili ndi ubwino wake: TPR ndi zinthu zosawononga chilengedwe komanso zopanda poizoni zomwe zimagwirizana ndi miyezo ya ROHS, REACH ndi zina zachilengedwe, ndipo zitha kugwiritsidwa ntchito kwambiri pazida zamankhwala, zoseweretsa za ana ndi zina. Mosiyana ndi zimenezi, ngakhale kuti rabara ya BR ndi zinthu zosawononga chilengedwe, ikhoza kuletsedwa ndi malamulo okhudza chilengedwe pazochitika zina.

Posankha ma caster, kuganizira mozama kuyenera kupangidwa kutengera zinthu monga momwe zimagwiritsidwira ntchito, zofunikira pakugwira ntchito, ndi malamulo okhudza chilengedwe. Mwachitsanzo, ma caster a TPR akhoza kukhala chisankho chabwino kwambiri pazochitika zomwe zimafuna kupanga bwino, mtengo wotsika komanso zofunikira pa chilengedwe, pomwe ma caster a rabara a BR angakhale oyenera pazochitika zomwe zimafuna kugwira ntchito bwino komanso kukana kutentha kwambiri.
