Ka tlase, re tla nka metsotso e 3 ho u ruta mokhoa oa ho khetholla melemo le mathata a thepa e meraro ea mantlha ea nylon, polyurethane le rabara, ho fana ka litlhahiso tsa ho reka tse thehiloeng tikolohong.
1. Kakaretso ea Boitsebiso
1). Nailone (PA)
• Mantsoe a bohlokoa: E thata, E boima, E lerata
• Likarolo: Ho thatafala ho hoholo, bokgoni bo botle ba ho jara mojaro, empa lerata le leholo la ho bilika; e hanela ho tsofala empa ha e "bonolo". Kamora ho sututsa le ho hula nako e telele e ka nna ya ngoatha fatshe la lehong kapa bokahodimo ba letsopa.
• Papiso e bonahalang: Jwalo ka mabili a koloi e seng tseleng, e ka jara meroalo e boima empa e duma haholo.
2). Polyurethane (PU)
• Mantsoe a bohlokoa: E tenyetsehang, E khutsitseng, E tenyetsehang
• Likarolo: Ho tenyetseha pakeng tsa polasetiki le rabara, lerata le tlase, ho hanela oli le hydrolysis. E loketse li-workshop tse se nang lerōle, lilaboratori, lipetlele le libaka tse ling tse nang le litlhoko tse tiileng; e mosa fatše, ha e siee matheba a matšo.
• Papiso e bonahalang: Joalo ka karolo e bohareng ea sneaker e nang le mosamo, e tsitsitse ebile e khutsitse.
3). Rabara (NR/SBR)
• Mantsoe a bohlokoa: E bonolo, E tšoarang, E theko e tlaase
• Likarolo: Ka tlhaho ha e thelle ka ho tshwara ka matla, ha e thelle ha e sututsa meroalo e boima; e monya meroalo e kentsweng kahare, e kgutsitse ebile e theko e tlase. Mathata a kenyeletsa ho tsofala ha e pepesehetse letsatsi nako e telele le ho fetoha ha meroalo e boima.
• Papiso e bonahalang: Joalo ka mabili a khutsitseng a koloi ea lelapa, e hloka ho sutumelloa "ka khutso" 'me e qoba ho imeloa ka nako e telele.

3. Monemoniki oa ho Reka oa Mehato e Meraro
1. Hlahloba fatše: Bakeng sa fatše le li-ceramic tsa lepolanka, o ka khetha PU kapa rabara; bakeng sa fatše tsa samente kapa tsa tšepe, nylon e loketse.
2. Mamela tikoloho: Bakeng sa liofisi le lipetlele tse hlokang "lerata le se nang letho", ho hlokahala ho qoba nylon.
3. Bekha mojaro: Bokgoni ba mojaro o le mong wa caster ≥ (boima bohle ba disebediswa ÷ 3), o siyang sebaka se lekaneng sa polokeho.
Kakaretso polelong e le 'ngoe
Mejaro e boima e se nang lerata—khetha nylon; batla khutso le bohloeki—khetha polyurethane; batla ho boloka chelete empa u khutse—khetha rabara. Bapisa thepa le boemo, 'me li-caster li ke ke tsa hlola li e-ba khetho e thata.
