Mukuongorora mhando dzakasiyana dzemavhiri eurethane, tinofanira kutaura nezvehunhu hwawo hwakasiyana uye mamiriro ekushandiswa kwawo. Polyurethane sechinhu chinoshanda zvakanaka. Iine hunhu hwayo hwepanyama uye hwemakemikari. Inobata chinzvimbo chakakosha mumunda wekugadzira mavhiri.
Kutanga. Ngatitarisei mavhiri e polyurethane (TPU). Mavhiri aya ane polypropylene kana nylon core. Kuburikidza ne secondary injection molding technology, A polyurethane wheel surface inoumbwa pamucheto wekunze we core. Mavhiri eTPU haana chete hunhu hwekudzivirira pasi, anonwisa kudedera, haaratidzi uye haana mavara. Anewo simba rakanaka rekukweshana nekuora. Anokwanisa kutenderera zviri nyore panzvimbo dzakasiyana-siyana. Pamusoro pezvo. Ruvara rwayo runogona kugadziriswa zvichienderana nezvinodiwa. Inoenderana nezvinodiwa zvezviitiko zvakasiyana. Zvisinei. Zvakakosha kuziva kuti munzvimbo inopisa. Kukwanisa kwekutakura kwevhiri reTPU kuchaderedzwa.
Danho rinotevera nderekudira vhiri re elastomer re polyurethane (CPU). Mavhiri aya ane musimboti wesimbi kana aluminium semusimboti. Ma elastomer e polyurethane anogadzirisa kupisa anoumbwa nemakemikari. Anogadzira pamusoro pevhiri mushure mekuoma pakupisa kwakanyanya. Mavhiri eCPU ane zvakanakira zvakafanana zvekudzivirira pasi, kusaisa nyora uye kusasvibisa. Anodzivirirawo UV uye haakwikwidzani, zvichiita kuti ive yakakodzera kushandiswa kunoda kunyaradzwa kwakanyanya. Zvisinei. Haapindi mumvura inopisa, utsi hwemvura, nezvimwewo… Saka kungwarira kunodiwa pakushandisa munzvimbo dzakatarwa.
Ngatitaurei nezverimwe vhiri re polyurethane (CPU). Mavhiri aya akavakirwawo pa thermoset polyurethane elastomers dzakaumbwa nemakemikari. Ane mabhenefiti akafanana neevhiri reCPU ratsanangurwa pamusoro apa, semuenzaniso, kudzivirira pasi, kudzivirira kukweshana, nezvimwewo. Zvinokosha zvikuru. Rine mwero wakaderera wekushanduka-shanduka kwechigarire, resistance yakaderera yekutenderera. Rinokwanisa kutsungirira mitoro inoshanduka nekumhanya kwakanyanya. Rakanakira kushandiswa mumamiriro ekumhanya kukuru.
Chekupedzisira. Ngatitarisei vhiri repolyurethane (PUE) rine furo. Nechimiro charo chakasiyana che microporous, vhiri iri rine hunhu hwakadai sehuremu hushoma, huremu hwakareruka uye nyore kuchinja. Rine hunhu hwakasiyana-siyana hwakanaka senge mutoro wakakwira, kuchinjika kwakanyanya uye kuramba kupetwa. Hunhu uhwu hwemavhiri ePUE hunoita kuti ave sarudzo yakanaka yezvinhu zve casters. Ingave yakanaka uye inonyudza simba kana kuti inodzikisa vibration uye inonamira. Ose anogona kuratidza mabhenefiti awo akasiyana.
Zvose. Mavhiri ePolyurethane, ane mashandiro awo akanaka uye mhando dzakasiyana dzemavhiri, anoshandiswa zvakanyanya muminda yakasiyana-siyana. Kubva kumavhiri eTPU anodzivirira pasi uye anotora kuvhunduka. Kusvika kuUV nekuramba kukweshana kwevhiri reCPU. Kuwedzera kune huremu hushoma uye huremu hwakareruka hwevhiri rePUE. Rudzi rwega rwega rwevhiri repolyurethane runoita basa rakakosha mumunda waro. Kusarudza vhiri reurethane rakakodzera zvaunoda. Hazvingowedzeri kushanda zvakanaka chete. Zvinopawo ruzivo rwakasununguka uye rwakachengeteka.
