Irabha kunye nepolyurethane zombini zizixhobo eziqhelekileyo zemizi-mveliso, kwaye zombini zizinto ezisisiseko ezisetyenziselwa ukwenza izinto zokunyathela ivili lecaster. Zombini izixhobo zineenzuzo zazo kunye nokungalunganga, kwaye icandelo elilandelayo liphonononga umahluko ngokweenkcukacha, kunye neemeko omele ukhethe kuzo ukuba yeyiphi na into.
Masiqale ngokujonga umahluko obonakalayo phakathi kwerabha kunye nepolyurethane. Irabha yinxalenye engqukuva eyenziwe ngezinto zerabha eziguquguqukayo ngokubanzi kwaye zingatyibiliki. Irabha ihlelwa ikakhulu ngokwerabha yendalo kunye nerabha eyenziweyo, kwaye inokulungiswa ukuze iqine kunye nokumelana nokukrala njengoko kufuneka. I-polyurethane iqinile kwaye iyaxhathisa ngakumbi kwi-abrasion kune-casters yerabha. Iicaster zePolyurethane zihlala zenziwe nge-polyurethane elastomers, ezinobunzima obuphezulu kunye nobunzima.
Okwesibini, i-rubber casters kunye ne-polyurethane casters zenza ngokungafaniyo kwiimeko ezahlukeneyo. Iirubha ezifakwa kwirabha zisebenza kakuhle ngokwemigaqo yokuguquguquka, ukunqanda ukutyibilika kunye nokugqunyelelwa kwesandi, kwaye amaxabiso aphantsi kwaye kulula ukusetyenzwa nokwenziwa. Ke ngoko, i-rubber casters lukhetho olungcono kwiimeko apho kufuneka ukuguquguquka kunye nokufunxa ukothuka, njengezixhobo zonyango, ifenitshala, izixhobo zombane kunye nezixhobo zemidlalo. I-Polyurethane casters, ngakolunye uhlangothi, yenza ngcono ngokumalunga nobunzima, ukuxhathisa i-abrasion, kunye nomthamo wokuthwala umthwalo, ngoko ke bafaneleka ngakumbi kwiimeko zoshishino, ukuvelisa, kunye nokwakhiwa apho ubunzima bufunekayo.
Ezi ntlobo zimbini ze-casters nazo zahlukile malunga nokhuseleko lokusingqongileyo. Iirubber casters zifuna ukusetyenziswa kweekhemikhali kwinkqubo yokuvelisa, ezifana ne-vulcanizing agents kunye ne-accelerators, ezinokungcolisa indalo. I-Polyurethane casters, kwelinye icala, ihambelana nokusingqongileyo njengoko iyinto enokuphinda isetyenziswe kwaye ivelise inkunkuma encinci ngexesha lenkqubo yokuvelisa.
Okokugqibela, ngokwexabiso, ii-rubber casters zinexabiso eliphantsi ngelixa ii-polyurethane casters zibiza kakhulu. Oku kungenxa yokuba izixhobo ze-polyurethane zibiza kakhulu kwaye zinzima kakhulu ukusetyenzwa, ngoko ke ii-polyurethane casters zibiza kakhulu. Iimathiriyeli zerabha, kwelinye icala, azibizi kakhulu kwaye inkqubo yokuvelisa ilula, ngoko ke ii-rubber casters zixabiso eliphantsi.
Ngoko ke, xa ukhetha i-rubber casters kunye ne-polyurethane casters, kufuneka ukhethe njani?
Enyanisweni, zombini zineenzuzo zabo kunye nokungonakali, kwaye ukhetho oluthile kufuneka luxhomekeke kwimeko. Ukuba ufuna i-elasticity, i-anti-slip kunye ne-shock-absorbing features, njengefenitshala, izixhobo zombane kunye nezixhobo zemidlalo, kufuneka ukhethe ii-rubber casters. Ukuba ufuna ii-casters ezinobunzima obukhulu kunye nokuxhathisa i-abrasion, njengakumashishini, ukuvelisa kunye nokwakhiwa, kufuneka ukhethe i-polyurethane casters.
Ngaphandle kwee-rubber casters kunye ne-polyurethane casters, kukho ezinye iintlobo ze-casters ezifana ne-nylon casters kunye ne-PP casters. Uhlobo ngalunye lwe-caster luneenzuzo kunye nokungalunganga kwaye kufuneka lukhethwe ngokweemfuno zangempela. Ukongeza, xa ukhetha ezi casters, kufuneka uhlawule ngakumbi ingqalelo ubukhulu ipleyiti yentsimbi yesibiyeli, izinto ipleyiti yentsimbi, ukuya kumlinganiselo omkhulu, imisela umthamo wokuthwala kunye nokhuseleko casters, akufanele ngoyaba, zama. ukukhetha uhlobo lwensimbi ye-manganese yezinto ze-caster, umgangatho kunye nokuthembeka kwayo kuphezulu kakhulu kunentsimbi eqhelekileyo.
Kakade ke, kufuneka kwakhona ingqalelo ubungakanani casters kunye nofakelo, ukuqinisekisa ufakelo egudileyo, ukuze ukusebenza kwayo eqhelekileyo.
