Munzvimbo yakakura yezvinhu zvinogadzirwa nesimbi, TPU, TPE neTPR pane zvinhu zvitatu zvakakwezva vanhu vakawanda. Chimwe nechimwe chine hunhu hwakasiyana hwekushanda uye chakakodzera kushandiswa kwakasiyana. Kune vanotenga zvinhu zvinogadzirwa nesimbi, zvakakosha kunzwisisa hunhu uye huwandu hwekushandiswa kwezvinhu izvi.
Zvinhu zveTPU Caster
Zvinhu zveTPU (thermoplastic polyurethane) zvinozivikanwa nekudzivirira kwayo kukwesha, kudzivirira mafuta, kutwasuka kwakanyanya uye kutakura mutoro. Izvi zvinoita kuti TPU caster compound ishandiswe zvakanyanya mumavhiri ekutakura zvinhu nemacaster mumaindasitiri mazhinji. Kudzivirira kwayo kukwesha kwakanyanya zvinoreva kuti inogona kuchengetedza kushanda kwayo kwakasimba kwenguva yakareba, zvichideredza kuora kwekushanda nekuda kwekusakara uye kuwanda kwekutsiva. Pamusoro pezvo, zvinhu zveTPU zvinoita ruzha pakushanda, asi izvi zvinoratidza kutakura kwayo mutoro kwakanaka uye kugadzikana. Zvisinei, zvinofanira kucherechedzwa kuti TPU haidziviriri hydrolysis, saka kusangana nemvura kwenguva refu kunofanira kudzivirirwa panguva yekushandiswa nekuchengetedzwa.
Zvinhu zveTPE caster
TPE (thermoplastic elastomer) caster compound inosanganisa kusimba kwakanyanya, simba uye kusimba kwerabha nehunhu hwejekiseni. Izvi zvinoita kuti TPE casters ive nyore uye inoshanda mukugadzirwa kwayo. Pamusoro pezvo, TPE casters dzine hushamwari kune nharaunda uye hadzina chepfu, dzine ruvara rwakanaka, kubata zvinyoro nyoro, kuramba mamiriro ekunze, kuramba kuneta uye kuramba tembiricha. Hunhu uhu hunoita kuti TPE caster material ishandiswe zvakanyanya mumaindasitiri akadai semavhiri ekutakura zvinhu nemavhiri etrolley. Kuramba kwayo kutsvedza, kusimba kwayo uye kubatwa nekuvhunduka kunoita kuti TPE caster material ishande zvakanaka kana ikabatwa nezvinhu zvinorema uye zvinorova. Panguva imwe chete, ruzha rwakaderera rweTPE caster material inoita kuti ive chinhu chinofarirwa pakutsvaga nzvimbo yakanyarara. Pamusoro pezvo, TPE caster material inogonawo kuputirwa nekusungirirwa nePP, PE, PC, PS, ABS nezvimwe zvinhu zvepasi, zvichiwedzera nzvimbo dzayo dzekushandisa.
Zvinhu zveTPR Caster
TPR (thermoplastic rabha) caster compound inogona kuonekwa semhando yeTPE (mumunda we polystyrene elastomer) neimwe nzira. Yakavakirwa paSBS uye ine elasticity iri nani pane TPE, asi hainyanyi kusimba pane TPE; zvisinei, TPR caster compound ine simba rakanaka rekudzivirira abrasion, elasticity, uye shock-absorption, zvichiita kuti ive yakakodzera kushandiswa senge heavy-duty casters iyo inosangana nematambudziko anorema. Pamusoro pezvo, TPR caster compound haina mari yakawanda pane TPE, zvichiita kuti ive nehupfumi. Kufanana neTPE, TPR caster material inogonawo kuumbwa nemapurasitiki akaoma akadai sePA nePP, zvichiwedzera kuchinjika kwayo pakushandiswa.
Pfupisa
Zvishandiso zveTPU, TPE neTPR zvine hunhu hwazvo uye mashandisirwo azvo. TPU inozivikanwa nekudzivirira kwayo kukuru kwekukwesha, kudzivirira mafuta uye hunhu hwekutakura mutoro; TPE inofarirwa nekuda kwekukwesha kwayo kwakanyanya, simba rayo guru uye kugona kwayo kugadzira jekiseni; TPR ine nzvimbo mumunda wezvishandiso zvinorema nekuda kwekukwesha kwayo kwakanyanya uye mutengo wayo wakaderera. Pakusarudza zvinhu izvi zvechishandiso, tinofanira kutonga zvichienderana nemamiriro chaiwo ekushandiswa uye zvinodiwa kuti tive nechokwadi chekuti zvinhu zvasarudzwa zvinogona kusangana nezvatinoda.
