M'moyo wathu watsiku ndi tsiku, ma casters ndi chowonjezera chofala, chomwe chimagwiritsidwa ntchito kwambiri mumipando yosiyanasiyana, zida ndi zida. Pakati pawo, PP casters ndi TPR casters ndi mitundu iwiri wamba. Nkhaniyi iwonetsa kusiyana pakati pa otulutsa PP ndi otulutsa TPR mwatsatanetsatane.
I. Kusiyana kwa Zinthu
Makasitomala a PP amapangidwa makamaka ndi zinthu za polypropylene, pomwe ma caster a TPR amapangidwa ndi zinthu za mphira wa thermoplastic. Chikhalidwe ndi makhalidwe a zipangizo ziwirizi ndizosiyana kwambiri.
Polypropylene (PP): Polypropylene ndi thermoplastic ya thermoplastic, yokhala ndi kukana kwambiri komanso kukana kwamankhwala, komanso yosavuta kuyipanga.PP zotulutsa nthawi zambiri zimakhala zolimba komanso zolimba, zoyenera nthawi zina zomwe zimafuna mphamvu zambiri.
Thermoplastic rabara (TPR): labala la thermoplastic ndi mtundu wa thermoplastic wokhala ndi kusungunuka kwa rabala, kusinthasintha kwabwino komanso kukana kuvala, ma caster a TPR nthawi zambiri amakhala ndi mawonekedwe ofewa, oyenera nthawi zomwe zimafunikira kukhazikika komanso chete.
Chachiwiri, mawonekedwe a ntchito
Kukaniza kwa Abrasion: Kukana kwa abrasion kwa ma casters a TPR ndi apamwamba kuposa a PP casters chifukwa ali ndi malo ofewa omwe amasintha bwino pansi.
Kukana kwamphamvu: Ngakhale ma casters a PP ali ndi kukana kwabwinoko, nthawi zina, ma casters a TPR amatha kukhala ndi kukana kwakukulu.
Processability: PP casters ndi osavuta kukonza ndipo akhoza kupangidwa jekeseni pa kutentha kwambiri. Makasitomala a TPR sasinthidwa ndipo nthawi zambiri amafuna kugwiritsa ntchito jekeseni wachiwiri.
Mtengo: Nthawi zambiri, ma casters a TPR ndi okwera mtengo kuposa ma PP casters chifukwa chazovuta kwambiri kupanga.
Kugwiritsa ntchito
PP casters: oyenera nthawi imene amafuna mkulu katundu kunyamula ndi mkulu kuvala kukana, monga katundu katundu, maalumali, etc.
TPR casters: oyenera kufunika kusinthasintha kwabwino, kukana kwamphamvu, kukana kuvala, monga zida zamankhwala, zida za labotale.
