Kev xaiv cov khoom siv rau cov menyuam yaus lub tsheb kauj vab yog lub hauv paus tseem ceeb uas txiav txim siab cov khoom lag luam muaj kev nyab xeeb, ua haujlwm ntev, thiab cov neeg siv kev paub. Vim tias cov menyuam yaus lub cev ua haujlwm tseem tsis tau tsim tiav, muaj cov kev cai tshwj xeeb rau lub tsheb sib tsoo cushioning, hnyav load-cov kabmob muaj peev xwm, thiab kev hloov pauv ib puag ncig. Kev xaiv cov khoom siv yuav tsum muaj qhov sib npaug ntawm lub zog, lub teeb yuag, kev tiv thaiv corrosion, thiab ib puag ncig tus phooj ywg, thiab ua kom muaj kev ruaj ntseg los ntawm cov qauv tsim khoom nruj.
Raws li lub hauv paus quab yuam-cov kabmob ntawm tag nrho lub tsheb kauj vab, cov khoom siv ntawm lub thav duab ncaj qha cuam tshuam rau kev nyab xeeb ntawm cov qauv. High- carbon steel, vim nws lub zog zoo thiab tawv, tuaj yeem nqus lub zog thaum caij tsheb, thiab nws cov nqi tswj tau ua rau nws siv dav hauv kev nkag- theem thiab nruab nrab- cov qauv. Rau cov khoom lag luam ua ntej tsim lub teeb yuag, aluminium alloy yog qhov kev xaiv. Its low density and ease of processing can significantly reduce the overall weight of the bicycle while maintaining strength, making it easier for young children to handle. Ntau dua - qauv kawg siv magnesium alloy, uas, ntxiv rau kev txo qhov hnyav ntxiv, kuj muaj kev ua haujlwm poob siab zoo, pab txhawb kev caij tsheb zoo dua. Txawm hais tias cov khoom siv hlau, txhua yam khoom siv yuav tsum tau tiv thaiv kev tiv thaiv corrosion, xws li pickling, phosphating, thiab electrostatic spraying, los tiv thaiv xeb los ntawm ya raws los yog hws, uas tuaj yeem cuam tshuam cov qauv kev ncaj ncees.
Cov khoom yas hauv cov menyuam yaus lub tsheb kauj vab feem ntau yog siv rau kev cob qhia log, mudguards, thiab handlebars. Kev xaiv cov khoom siv yuav tsum sib npaug qhov cuam tshuam nrog kev ua phooj ywg ib puag ncig thiab tsis yog - toxicity. ABS resin, vim nws lub zog muaj zog thiab qhov ruaj khov, yog siv dav hauv cov khoom uas yuav tsum tau ua haujlwm ntev; polypropylene (PP), nrog nws lub teeb yuag thiab zoo toughness, yog tsim rau ua kom yooj yim skid daim hlau thiab hauv ob sab phlu. Txhua cov ntaub ntawv yas yuav tsum ua raws li cov qauv kev nyab xeeb hauv lub tebchaws rau cov khoom siv menyuam yaus, txwv tsis pub siv cov khoom siv phom sij xws li phthalates kom ntseeg tau tias kev sib cuag ntev ntev yuav tsis muaj kev phom sij rau kev noj qab haus huv.
Cov khoom siv roj hmab hauv cov log tsheb thiab cov tuav tuav tuav tau los tiv thaiv - plam thiab poob siab. High-cov qauv zoo ntawm ntuj lossis hluavtaws roj hmab muab kev tuav kom haum thiab elasticity, yoog raws ntau txoj hauv kev, thaum tswj kev ua haujlwm ruaj khov nyob rau hauv ultraviolet hluav taws xob thiab ozone, ncua kev pab cuam lub neej.
Cov ntaub ntawv txheej kuj tseem ceeb heev. Cov menyuam yaus lub tsheb kauj vab feem ntau siv cov hmoov txheej zoo ib puag ncig, uas tsim cov txheej txheej tiv thaiv zoo tom qab kho. Cov txheej no tsis yog tsuas yog hnav- tiv taus thiab khawb- tiv taus tab sis kuj zam kev ua pa ua pa los ntawm cov kuab tshuaj evaporation, ua raws li cov qauv ntawm cov khoom ntsuab rau cov menyuam yaus cov khoom.
Hauv cov ntsiab lus, kev xaiv cov khoom siv rau cov menyuam yaus lub tsheb kauj vab yuav tsum ua qhov tseem ceeb ntawm kev nyab xeeb. Raws li cov menyuam yaus cov yam ntxwv ntawm lub cev thiab kev siv ib puag ncig, kev sib koom ua ke ntawm cov hlau, yas, roj hmab, thiab cov coatings yuav tsum ua kom muaj kev sib npaug ntawm kev ua haujlwm, hnav thiab tswj tau yooj yim, thiab kev noj qab haus huv thiab ib puag ncig tus phooj ywg, muab kev tiv thaiv cov khoom siv txhim khu kev qha rau kev caij tsheb.
