      2. Iindawo ezahlukeneyo
      Inkulu - Iziganeko zebhasikiti yebhasikiti zonke zichaza ukusetyenziswa kweebhasikithi ezenziwe ngezinto ze-PU, ukuze kuvumeleke iimbaleki zenza ngcono, ngelixa iibhola ze-ruber zizinto zokuzonwabisa zemihla ngemihla.
      3. Imvakalelo eyahlukileyo yokusebenzisa
      Iibhasikithi zerabha ziziva zilukhuni; Ii-pubotchballs zenziwe ngesikhumba sokwenziwa, ezikhululekile kakhulu ngokwendlela ye-elasticity kwaye ivakale.
      4. Amaxabiso ahlukeneyo
      Iibhasikithi zerabha zixabiso eliphantsi kwaye zilungele abantwana kunye nokuzonwabisa; Iibhasikithi zebhasikithi zibiza kakhulu kwaye zilungele abaqalayo kunye nenzondelelo yebhasikiti.
      5. Iidigri ezahlukeneyo zokunganyangeki
      Iibhasikithi zerabha zine-elasticity kwaye azinzima kakhulu xa ziyinto epheleleyo, kwaye umphezulu wazo wonakaliswa ngokulula (apha apha ubhekisa ekubonakaleni kwamanzi); I-PU Basketballs inee-elasticys nje ezifanelekileyo kwaye zinzima xa i-inveres, kunye nomphezulu ocothayo xa uphuma.
      Izibonelelo ze-pubosketball nebhola yerabha:
      Ukuxhathisa i-pusketball ihlala ininzi kakhulu ukuya kumaxesha amaninzi eneerabha eziqhelekileyo. Izinto ze-PU zisetyenziswa ngokubanzi kubomi benene kwaye zinobuhlobo bokusingqongileyo. Ukusebenza kwayo kuyo yonke imiba kufutshane okanye kubhetele kunesikhumba sokwenyani.
      Isikhumba se-puse ngokubanzi ibhekisa kwisikhumba se microfiber. Igama elipheleleyo le-microfiber ulusu yi "microfiber yobisi". Inxibe kakhulu ukunyangwa, ukunyangwa okugqwesileyo kunye nokungaxhathisi okugqwesileyo, ithambile kwaye ukhululekile, ixhaswe ngokupheleleyo kukhuseleko lwendalo.
      I-Braberball yebhola yerabha ine-elaistity ephezulu kunye ne-elastic ephantsi. Ngokuqhelekileyo inesiphene esikhulu se-slongngetion phakathi kwe-1 ne-9.8MPA. I-elongition inokuba phezulu njenge-1000%. Ibibonisa iimpawu ezifumanekayo kwaye zinokusetyenziswa kuluhlu olubanzi lwamaqondo obushushu (- ihlala ilandelana ngaphakathi kuluhlu lwama-50 ukuya kwi-150 ℃).
      I-viscoelity yebhasikithi yerabha. Irabha ngumzimba we-viscoelastic. Ngenxa yobukho bemikhosi phakathi kweMacromolecules, irabha ichaphazelekile yimikhosi yangaphandle. Xa ukuvela kwenzeke, kuyachaphazeleka ziimeko ezinjengexesha kunye nobushushu, kunye nokubonisa ukuphumla ocacileyo kunye ne-cenomena.
