Irabha kunye ne-polyurethane zombini zizinto eziqhelekileyo zoshishino, kwaye zombini zizinto ezisisiseko ezisetyenziselwa ukwenza izinto ze-caster wheel tread. Zombini ezi zinto zineengenelo kunye neengxaki zazo, kwaye eli candelo lilandelayo lihlola umahluko ngokweenkcukacha, kunye neemeko apho kufuneka ukhethe ukuba zeziphi izinto.
Masiqale ngokujonga umahluko okhoyo phakathi kwerabha kunye ne-polyurethane. Irabha yinxalenye engqukuva eyenziwe ngezinto zerabha eziguquguqukayo kwaye ezingatyibilikiyo. Irabha ikakhulu yahlulwe yaba yirabha yendalo kunye nerabha yokwenziwa, kwaye inokulungiswa ukuze ihambelane nobunzima kunye nokumelana nokukrazuka njengoko kufuneka. I-Polyurethane ngokubanzi iqinile kwaye imelana nokukrazuka ngakumbi kunee-casters zerabha. Ii-casters ze-polyurethane zihlala zenziwe ngee-elastomers ze-polyurethane, ezinobunzima kunye nobunzima obuphezulu.
Okwesibini, ii-rubber casters kunye nee-polyurethane casters zisebenza ngokwahlukileyo kwiimeko ezahlukeneyo. Ii-rubber casters zisebenza kakuhle ngokubhekiselele ekuguquguqukeni, ekuthinteleni ukutyibilika kunye nokuthintela isandi, kwaye zibiza kancinci kwaye kulula ukuzicubungula nokukwenza. Ke ngoko, ii-rubber casters zikhetho olungcono kwiimeko apho kufuneka ukuguquguquka kunye nokufunxwa komothuko, njengakwizixhobo zonyango, ifenitshala, izixhobo ze-elektroniki kunye nezixhobo zemidlalo. Ii-polyurethane casters, kwelinye icala, zisebenza ngcono ngokubhekiselele kubulukhuni, ukumelana nokukruquka, kunye nomthamo wokuthwala umthwalo, ngoko ke zifanelekile ngakumbi kwiimeko zoshishino, zokuvelisa, kunye nezokwakha apho kufuneka ukuthwala ubunzima.
Iindidi ezimbini zee-casters zahlukile ngokubhekiselele kukhuseleko lokusingqongileyo. Ii-casters zerabha zifuna ukusetyenziswa kweekhemikhali kwinkqubo yokuvelisa, ezifana nee-vulcanizing agents kunye nee-accelerators, ezinokungcolisa okusingqongileyo. Ii-casters ze-polyurethane, kwelinye icala, zinobuhlobo nokusingqongileyo ngakumbi kuba zizinto ezinokuphinda zisetyenziswe kwaye zivelisa inkunkuma encinci ngexesha lenkqubo yokuvelisa.
Okokugqibela, ngokwexabiso, ii-casters zerabha zibiza kancinci ngelixa ii-polyurethane casters zibiza kakhulu. Oku kungenxa yokuba izinto ze-polyurethane zibiza kakhulu kwaye kunzima ukuzicubungula, ngoko ke ii-polyurethane casters zibiza kakhulu. Izinto zerabha, kwelinye icala, zibiza kancinci kwaye inkqubo yokwenziwa ilula, ngoko ke ii-casters zerabha zibiza kancinci.
Ngoko ke, xa ukhetha ii-casters zerabha kunye nee-polyurethane casters, ufanele ukhethe njani?
Enyanisweni, zombini zinezibonelelo kunye neengxaki zazo, kwaye ukhetho oluthile kufuneka luxhomekeke kwimeko. Ukuba ufuna izinto ezithambileyo, ezingatyibilikiyo kunye neempawu zokufunxa ukutshaqeka, ezifana nefenitshala, izixhobo ze-elektroniki kunye nezixhobo zemidlalo, kufuneka ukhethe ii-casters zerabha. Ukuba ufuna ii-casters ezinobunzima obukhulu kunye nokumelana nokukrala, njengakwishishini, kwimveliso nasekwakhiweni, kufuneka ukhethe ii-casters ze-polyurethane.
Ngaphandle kwee-casters zerabha kunye nee-polyurethane casters, kukho ezinye iintlobo zee-casters ezifana nee-casters ze-nylon kunye nee-PP casters. Uhlobo ngalunye lwe-caster luneengenelo kunye neengxaki zalo kwaye kufuneka lukhethwe ngokweemfuno zokwenyani. Ukongeza, xa ukhetha ezi casters, kufuneka unikele ingqalelo engakumbi kubukhulu bepleyiti yentsimbi yebracket, izinto zepleyiti yentsimbi, ngokubanzi, zimisela amandla okuthwala kunye nokhuseleko lwee-casters, akufuneki zinganakwa, zama ukukhetha uhlobo lwentsimbi ye-manganese ye-caster, umgangatho kunye nokuthembeka kwayo kuphezulu kakhulu kunentsimbi eqhelekileyo.
Kakade ke, kufuneka sinikele ingqalelo kubungakanani bee-casters kunye nofakelo, ukuqinisekisa ukufakwa okugudileyo, ukuze ukusebenza kwayo kube ngokwesiqhelo.
