Musiyano pakati pePP casters uye TPR casters

Muhupenyu hwedu hwezuva nezuva, casters chinhu chakajairika, chinoshandiswa zvakanyanya mune dzakasiyana fenicha, maturusi nemidziyo. Pakati pavo, PP casters uye TPR casters marudzi maviri akajairika. Ichi chinyorwa chichasuma musiyano pakati pePP casters uye TPR casters zvakadzama.

I. Misiyano Yezvinhu
PP macaster anonyanya kugadzirwa ne polypropylene zvinhu, nepo TPR macaster anogadzirwa ne thermoplastic rubber zvinhu. Hunhu uye maitiro ezviviri izvi zvakasiyana zvakanyanya.

Polypropylene (PP): Polypropylene is semi-crystalline thermoplastic, ine high impact resistance uye chemical resistance, uye iri nyore kugadzirisa.PP macaster anowanzo kuve nekuoma kwakanyanya uye simba, akakodzera kune dzimwe nguva dzinoda hukuru hwekuremerwa.
Thermoplastic rabha (TPR): thermoplastic rabha imhando ye thermoplastic ine rubber elasticity, yakanaka kuchinjika uye kupfeka kuramba, TPR casters kazhinji ine yakapfava magadzirirwo, akakodzera kune zviitiko zvinoda cushioning uye kunyarara.

Chechipiri, maitiro ekuita
Abrasion Resistance: The abrasion resistance yeTPR casters yakakwirira kune iyo yePP casters nokuti ine nzvimbo yakapfava inogadzirisa zvirinani pasi.
Impact kuramba: Kunyangwe maPP casters aine zvirinani kukanganisa kuramba, mune dzimwe nguva, TPR casters inogona kuve nepamusoro pesimba kuramba.
Processability: PP casters ari nyore kugadzirisa uye anogona kuumbwa jekiseni pakupisa kwakanyanya. TPR casters haigadzirike uye kazhinji inoda kushandiswa kwechipiri jekiseni molding.
Mutengo: Kazhinji, TPR casters inodhura kupfuura PP casters nekuda kweiyo yakanyanya kuoma kugadzirwa maitiro.

Application
PP casters: inokodzera zviitiko zvinoda yakakura kutakura mutoro uye yakakwirira kupfeka kuramba, senge inorema midziyo, masherufu, nezvimwe.
TPR casters: inokodzera kudiwa kwekuchinjika kwakanaka, yakanaka kukanganisa kuramba, kupfeka kuramba, senge michina yekurapa, midziyo yemurabhoritari.
