Mu bidukikije bya none by’inganda n’ubucuruzi, Amapine akozwe mu bikoresho bitandukanye akoreshwa cyane mu bihe bitandukanye bitewe n’imiterere yayo yihariye. Kuva ku mapine ya nylon, amapine ya nylon (MC). kugeza ku mapine akomeye ya rubber, amapine ya rubber yoroshye. Hanyuma kugeza ku mapine ya rubber ya sintetike, amapine ya rubber ya sintetike arwanya static. kimwe n’amapine ya pompe n’amapine y’icyuma. Buri pine muri aya ni umwihariko kandi rihaza ibidukikije bitandukanye bigoye ku butaka n’ibisabwa mu gutwara imizigo. Ibikurikira. Tuzavuga kandi ku bundi bwoko bwinshi bw’amapine.
Ipine ya polypropylene, izwi cyane nka PP wheel
Polypropylene ni ibikoresho bya thermoplastic bizwiho kudakora neza, kudakora neza, kudakora neza, kudasiga ibara, kudasiga ibara kandi ntibigire uburozi. Iki gikoresho ntikigira impumuro mbi, ntigikoresha hygroscopic kandi kirwanya ibintu byinshi byangiza. Ariko, ntabwo kirimo ibintu bikomeye bigabanya ubushyuhe n'ibintu bya halogenated. Amapine ya polypropylene akwiriye ubushyuhe buri hagati ya -20°C na +60°C. Ariko, iyo ubushyuhe buri hejuru ya +30°C, ubushobozi bwo gutwara buzagabanuka.
Ipine ya Polyurethane
Polyurethane (TPU) ni polyurethane ikoresha thermoplastic. Izi pine zifite polypropylene cyangwa nylon. Polyurethane ishyirwa ku nkengero z'inyuma z'inyuma kugira ngo ikore isura y'ipine. Izi pine za polyurethane zifite imiterere myiza yo kurinda hasi, zifata umuyaga, ntizigaragaza ibimenyetso, ntizisiga ibara, zirambaraye, ntizishobora kwangirika kandi ntizishobora kwangirika bitewe n'ibintu byinshi bikaze. Byongeye kandi, irwanya amazi ashyushye n'umwuka w'amazi mu bihe bimwe na bimwe. Irwanya kuzunguruka kwayo ni nto. Ikwiriye ahantu henshi ho hasi. Amabara ashobora gukorwa iyo ubisabye. Ihuye n'ibikenewe bitandukanye. Ifite thermoplastic polyurethane monowheels ikwiriye ubushyuhe buri hagati ya -45 °C na +90 °C. Ariko, ubushobozi bwo gutwara imizigo buragabanuka iyo ubushyuhe buri hejuru ya +35 °C.
Uruziga rwa Elastomer rwa Polyurethane (CPU) rwakozwe mu buryo bwa Cast
Elastomer za polyurethane zikozwe mu buryo bwa cast polyurethane (CPUs) ni elastomer za polyurethane zikoreshwa mu buryo bwa thermosetting zikozwe mu buryo bwa chemical reaction. Ibikoresho by'ibanze birimo polyester polyols, diisocyanates na glycols. Ubu bwoko bw'uruziga bukoresha icyuma cyangwa aluminiyumu nk'ishingiro, kandi polyurethane isuka ku nkengero z'inyuma z'ishingiro. Ubuso bw'uruziga bukorwa no gukaraba ku bushyuhe bwinshi. Amapine ya polyurethane asutswe akingira cyane ubutaka, atuma buhindagurika, nta bimenyetso, nta mabara, nta gukurura neza, nta gucika intege neza, arwanya ingese n'ibintu byinshi bikaze, arwanya UV. Byongeye kandi. Afite urwego rwo hejuru rwo gukora neza, nta guhindagurika cyane. Nta gushyuha cyane iyo ashyizwe mu mitwaro ihindagurika. Ibara ni umweru. Ikwiriye ubushyuhe buri hagati ya -30°C na +70°C. Kugeza +90°C mu gihe gito. Ku bushyuhe buri munsi ya -10°C. Uburimbane bwayo bukora neza cyane.
Irindi ruziga rwa polyurethane (CPU) rukozwe mu cyuma gikozwe mu cyuma
Izi pine za polyurethane (CPU) zishingiye kandi kuri elastomer za polyurethane zikoresha thermosetting zikozwe mu buryo bwa chemical reaction. Zubatswe kuri polyole za polyester, diisocyanates na glycols. Zifite imiterere yo kurinda ubutaka, kudashyira ibimenyetso, kudasiga ibara, kudatera friction, flexibility nziza no kurwanya ingese y'ibintu byinshi bikaze. Zirwanya kandi UV. Zifite urwego ruto cyane rwo guhinduka burundu. Zirwanya buhoro. Zitanga ubushyuhe buke iyo zishyizwe mu mitwaro ihindagurika. Kandi zirwanya hydrolysis. Zikwiriye cyane cyane umuvuduko wo hejuru kugeza kuri 16km/h. Amabara ashobora guhindurwa iyo ubisabye. Ingano y'ubushyuhe ikoreshwa iri hagati ya -45°C na +90°C, mu gihe gito ntarengwa kingana na +90°C.
Ipine ya Polyurethane (PUE) ifite ifuro
Amapine ya polyurethane (PUE) afite ifuro. Azwi kandi nka polyurethane ifite imyenge mike. Ni polymeri ifite bloc. Aya mapine arangwa no gukomera neza, imiterere yayo irenze iy'andi mapine afite imyenge mike afite ubucucike bumwe. Amapine ya polyurethane afite ifuro afite imiterere myiza nko kuba afite ubucucike buke, uburemere bworoshye, yoroshye guhindura, yoroshye gushushanya, adashobora gutera, acoustic nziza, umutwaro mwinshi, agorana cyane, agorana neza gupfunyika, agorana hasi, agorana gushwanyagurika, agorana gucika, agorana kurabagirana, agorana imirasire n'agorana. Afite ubwoko bwinshi bw'ubukomere. Kuva ku nkombe ya A10 kugeza ku 100, ni byiza gukoreshwa nk'ibikoresho bya caster.
Muri rusange. Buri ruziga rufite ubwoko bwarwo. Buri rumwe rufite imiterere yarwo mu bijyanye n'ibikoresho, imikorere n'ibidukikije birukwiriye. Mu gihe cyo guhitamo uruziga, tugomba kuruhuza dukurikije uburyo bwihariye bwo gukoresha n'ibyo dukeneye kugira ngo tumenye neza ko uruziga rukwiriye rutoranywa. Bityo, rukora neza.
