Yakasiyana-siyana macaster (hardware, fenicha, indasitiri) muhupenyu hwezuva nezuva, senge stroller casters, mikwende casters, maindasitiri masherufu casters, nezvimwewo, anowanzo gadzirwa nerabha, furo EVA, PU nezvimwe zvinhu.Kukunguruka kweruzha pasi kune ruzha.Izvi zvinoita kuti nzanga yagara ine manyawi ive neruzha uye ruzha.
Kuenzaniswa nemakasiti ezuva nezuva, makanda anoshandiswa muindasitiri yezvokurapa haana kunhuhwirira kusingafadzi, uye hapana ruzha kana uchikwesha pamusoro pevhu, iro rinosangana zvizere nezvinodiwa zveindasitiri yezvokurapa.Chii chakavanzika apa?
Zvinoitika kuti macasters ekurapa anoshandisa nharaunda, isina-chepfu uye isina kunhuhwirira thermoplastic elastic TPE/TPU (pfupiso: polyurethane) sechinhu chekunze kweganda recaster.Zvigadzirwa zveTPU zvine simba rakatanhamara rekubereka, kukanganisa kupikisa uye kuita kwekuvhunduka, saka ndiyo yekutanga sarudzo kune yekunze lining yevatambi vekurapa.
Mazhinji ma stroller casters akagadzirwa ne vulcanized rabha kana EVA furo zvinhu, ine kunhuhwirira kwakasimba uye ine hanya nekuchengetedzwa kwezvakatipoteredza uye chengetedzo.Mazhinji maindasitiri macaster uye mabhegi ekutakura anoshandisa PU sechinhu chekutsika.Kunyange zvazvo vane simba rekudzivirira kupfeka, nekuda kwekupikisa kwakanyanya kwepasi, ruzha rwakanyanya panguva yekukunguruka.
Nekudaro, iyo ine hushamwari TPE/TPU zvinhu haiwedzeri phthalate plasticizers, sulfur, DCP uye mamwe ane muchetura cross-linking agents panguva yekugadzira, uye chinhu chisina chepfu zvachose.Zvakare, iyo TPE/TPU thermoplastic elastomer zvinhu ine yakarebesa mamorekuru cheni chimiro, uye friction coefficient inosangana nepasi idiki, uye hapana ruzha kana ichikwesha pasi.Panguva imwecheteyo, iyo yakakosha styrene-butadiene block chimiro cheTPE/TPU zvinhu inova nechokwadi chekuti zvinhu zvine simba rakawanda uye kupfeka kuramba.Chakavanzika che "vane ushamwari hwezvakatipoteredza uye vakanyarara" vateki vezvokurapa vari mune izvi.
Rudzi urwu rwekunyarara caster harushandiswe chete muindasitiri yezvokurapa, asiwo inozivikanwa mune mamwe maresitorendi epamusoro-soro, horo dzekumirira airport nedzimwe nzvimbo.
Nedhizaini yakaitwa nevanhu, kugadzirwa kwakanaka, chimiro chevhiri rakanaka uye hunhu hwakavimbika, SKERI casters yakahwina kufarirwa nezvipatara zvakawanda zvinozivikanwa uye masangano ekurapa.Kubva pakavambwa kambani, makumi emamiriyoni eSKRI casters akashandiswa neanodarika miriyoni imwe masangano ekurapa, achigadzira nzvimbo iri nyore uye yakachengeteka yekushanda kune vazhinji vevashandi vekurapa.Sikri casters yave zvishoma nezvishoma yave yakasarudzika caster mhando yemasangano ekurapa.
