Maviri - ruvara chena uye orenji yevana yekudzidzira basketball pu isiri - kutsvedza uye kupfeka - kuramba basketball

Ndeupi musiyano pakati pePu uye rabha:
1. Zvishandiso zvakasiyana
Rubber Basketballs akagadzirwa neRabha; Pu basketballs akagadzirwa neganda rekugadzira.
2. Nzvimbo dzakasiyana
Zvikuru
3. Kunzwa kwakasiyana kwekushandiswa
Rubber basketballs anonzwa zvakaoma; Pu basketballs akagadzirwa neganda rekugadzira, iro rakanyatsogadzikana maererano nekukasira uye kunzwa.
4. Mitengo Yakasiyana
Rubber Basketballs idzo dzakachipa uye dzakakodzera kuvana nevaraidzo; Pu basketballs idzo dzinodhura uye dzakakodzera kune vanotanga uye basketball vanofarira.
5. Dhigirii dzakasiyana dzekupfeka kurwisa
Rubber Basketballs ine yakasimba elasticity uye haina kunyanya kuomarara kana yakazara yakazara yakazara, uye nzvimbo dzadzo dzisiri nyore kukuvara (pano rinoreva kudzora kwemvura); Pu basketballs ane chete elasticity yakanaka uye yakaoma kana yakanyarara yakakwana, uye pamusoro penzvimbo dziri nyore kana dzakanyorova.
Zvakanakira Pu Basketball uye Rubber Basketball:
Kupfeka kupokana kwe pu basketball kunowanzoverengeka kune nguva nenguva iyo yeyakajairika yerabha yerabha. Pu zvinyorwa zvinonyanya kushandiswa muhupenyu chaihwo uye kune zvakatipoteredza hushamwari. Kuita kwayo mune zvese zvikamu zviri pedyo kana zviri nani pane ganda rechokwadi.
Ph ganda rinowanzo kureva kune microfiber dehwe. Iro zita rizere reCheese Forther Leather ndeye "microfiber yakasimbiswa yeganda". Iyo ine yakanyanya kunaka kupfeka kupokana, kudzivirirwa kwakanakisa uye kukwezva kupokana, kwakapfava uye kugadzikana, kunokanganisa uye kwakasarudzika uye parizvino kutsigirwa nekuchengetedza kwezvakatipoteredza.
Rubber Basketball ine yakakwira elasticity uye yakaderera elastic modulus. Iyo inowanzove ine yakakura learform deformation pakati 1 ne9.8mpa. Kureba kunogona kuve kwakakwirira kunge 1000%. Iyo ichiri inoratidza humbowo uye inogona kushandiswa mune dzakasiyana siyana dzekupisa (- inoramba iri elastic mukati memhando makumi mashanu kusvika zana nemakumi mashanu.
Iyo viscoellasity yebhasibha basketball. Rubber ndeye viscoelastic muviri. Nekuda kwekuvapo kwemauto pakati pamashomolecules, rubber inokanganiswa nemasimba ekunze. Kana deformation ikaitika, inokanganiswa nemamiriro ezvinhu senge nguva uye tembiricha, uye kuratidzira pachena kusagadzikana kwekuzorora uye creep zviitiko.
