Munzvimbo yemazuva ano yeindasitiri nekutengeserana, maWheels akagadzirwa nezvinhu zvakasiyana-siyana anoshandiswa zvakanyanya mumamiriro akasiyana-siyana nekuda kwehunhu hwawo hwakasiyana. Kubva pamavhiri enylon, mavhiri enylon (MC) akaumbwa. kusvika pamatayi erabha akasimba, mavhiri erabha akapfava. Zvadaro kusvika kumavhiri erabha akaumbwa, mavhiri erabha akaumbwa asingagadzike. pamwe nemavhiri epombi nemavhiri esimbi akaumbwa. Rimwe nerimwe remavhiri aya rakasiyana uye rinogutsa nzvimbo dzakasiyana-siyana dzakaoma dzepasi uye zvinodiwa zvekutakura mutoro. Zvinotevera. Tichataurawo nezvemamwe marudzi akati wandei emavhiri.
Vhiri rePolypropylene, rinozivikanwa sevhiri rePP
Polypropylene ipurasitiki inodziya. Inozivikanwa nekudzivirira kwayo kukuvadzwa, kuramba ngura, kuramba kukweshana, kusaisa mavara, kusasvibisa uye kusakuvadza. Iyi ipurasitiki haina hwema, haina hygroscopic uye inodzivirira zvinhu zvakawanda zvinoparadza. Zvisinei, haina oxidizing agents dzakasimba uye halogenated compounds. Mavhiri epolypropylene akakodzera tembiricha inotangira pa -20°C kusvika +60°C. Zvisinei, kana tembiricha iri pamusoro pe +30°C, kugona kwayo kutakura kunodzikira.
Vhiri rePolyurethane
Polyurethane (TPU) ipurasitiki yepurasitiki. Mavhiri aya ane polypropylene kana nylon core. Polyurethane inopinzwa zvakare kumucheto wekunze kwepakati kuti igadzire vhiri. Mavhiri epolyurethane ane hunhu hwakanaka hwekudzivirira pasi, anonwisa kudedera, haaratidzi mavara, haasvibisi, anochinjika, haakwikwidzi uye haaparadzi ngura nezvinhu zvakawanda zvinokasharara. Pamusoro pezvo. Inodzivirirawo mvura inopisa uye utsi hwemvura pasi pemamwe mamiriro. Kuramba kwayo kutenderera kwakaderera. Yakakodzera pasi rakasiyana-siyana. Mavara anogona kugadzirwa kana akumbirwa. Inosangana nezvinodiwa zvakasiyana. Mavhiri epolyurethane epurasitiki akakodzera tembiricha inotangira pa -45 °C kusvika +90 °C. Zvisinei, kugona kwekutakura mutoro kunoderera patembiricha iri pamusoro pe +35 °C.
Wheel yeElastomer yePolyurethane (CPU) yakakandwa
Ma cast polyurethane elastomers (CPUs) i thermosetting polyurethane elastomers dzinoumbwa ne chemical reaction. Zvinhu zvekutanga zvinosanganisira polyester polyols, diisocyanates uye glycols. Rudzi urwu rwevhiri runoshandisa iron kana aluminium core secore, uye polyurethane inodururwa pamucheto wekunze wecore. Pamusoro pevhiri rinoumbwa nekuoma pakupisa kwakanyanya. Mavhiri e polyurethane akadururwa anodzivirira pasi zvakanyanya, Absorb vibration, non-marking, non-daining, good friction resistance, good elasticity, resistance to corrosion nezvinhu zvakawanda zvinokatyamadza, resistance of UV. Pamusoro pezvo. Ine mwero wepamusoro wekushanda, Low rolling resistance. Inoderedza kupisa kana ichiiswa mu dynamic loads. Ruvara rwayo ruchena. Yakakodzera tembiricha dzinotangira -30°C kusvika +70°C. Kusvika +90°C kwenguva pfupi. patembiricha iri pasi pe -10°C. Kuoma kwayo kunoshanda zvakanaka.
Rimwe vhiri re polyurethane (CPU) rakaumbwa
Mavhiri aya e cast polyurethane (CPU) akavakirwawo pama thermosetting polyurethane elastomers anoumbwa nemakemikari. Akavakirwa pama polyester polyols, diisocyanates uye glycols. Ane hunhu hwekudzivirira pasi, kusaisa mavara, kusasvibisa, kuramba kukweshana, kusimba kwakanaka uye kuramba ngura yezvinhu zvakawanda zvinokasharara. Anodzivirirawo UV. Ane mwero wakaderera wekushanduka-shanduka zvachose. Anodzivirira kutenderedza kwakaderera. Anodzivirira kupisa zvishoma kana aiswa mu dynamic loads. uye anodzivirira hydrolysis. Anonyanya kukodzera kumhanya kwepamusoro kusvika 16km/h. Mavara anogona kugadziriswa kana akumbirwa. Tembiricha yakakodzera iri pakati pe -45°C ne +90°C, ine nguva pfupi yepamusoro ye +90°C.
Vhiri rePolyurethane (PUE) rine furo
Mavhiri epolyurethane ane furo (PUE). Anozivikanwawo se microporous polyurethane. I polymer ye block. Mavhiri aya ane kusimba kwakanaka, hunhu hwayo hwepanyama hunopfuura hwemamwe ma microporous elastomers ane density yakafanana. Mavhiri epolyurethane ane furo ane hunhu hwakanaka hwakadai se low density, huremu hwakareruka, nyore kuchinjika, nyore kuumba, inodzivirira kukanganiswa, acoustic absorption yakanaka, high load bearing, high elasticity, inodzivirira kupeta zvakanaka, low pressure resistance, abrasion resistance, closure resistance uye shock absorption uye buffer. Ane kuoma kwakasiyana-siyana. Kubva ku Shore A10 kusvika ku100, yakakodzera kushandiswa sechinhu che caster.
Zvose. Mavhiri ese aya ane seti yawo. Rimwe nerimwe rine hunhu hwaro maererano nemidziyo, mashandiro uye nzvimbo inoshanda. Pakusarudza mavhiri, tinofanira kugadzira izvi zvichienderana nemamiriro ezvinhu chaiwo ekushandiswa uye zvinodiwa. kuve nechokwadi chekuti vhiri rakakodzera rasarudzwa. Saka, rinoshanda zvakanaka.
