Raws li cov khoom siv hauv tsev uas sib koom ua ke kev noj qab haus huv thiab kev hloov pauv ntawm qhov chaw, kev tshawb fawb ntawm cov khoom siv hauv lub rooj zaum zaws ncaj qha txiav txim siab cov khoom thauj khoom- bearing stability, neeg siv kev nplij siab, thiab ntev -lub sij hawm durability. Thaum lub sij hawm tsim thiab tsim cov txheej txheem, cov khoom sib txawv yuav tsum tau xaiv cov ntaub ntawv tsim nyog raws li lawv qhov chaw ua haujlwm kom ua tiav kev ua kom zoo tshaj plaws ntawm kev txhawb nqa tshuab, kev paub txog tactile, thiab kev tiv thaiv ib puag ncig.
Cov khoom siv tseem ceeb yog qhov tseem ceeb ntawm kev txiav txim siab lub zog ntawm lub rooj zaum folding. Tam sim no, cov kev xaiv tseem ceeb suav nrog aluminium alloy thiab siab - zog engineering plastics. Aluminium alloy thav duab paub txog lawv lub teeb yuag, tiv thaiv corrosion, thiab muaj zog deformation tsis kam, tswj cov duab ruaj khov thaum rov folding thiab unfolding, thiab txo qhov hnyav piv rau cov tsoos steel thav duab, yooj yim tuav thiab khaws cia. Qee cov qauv siab- kawg siv aerospace-qib aluminium-magnesium alloy, uas txhim kho qhov tawv tawv los ntawm kev kho cua sov, ntsuas qhov hnyav thiab siab load-cov kabmob muaj peev xwm. Engineering yas thav duab, ntawm qhov tod tes, ua tiav kev sib koom ua ke ntawm cov txheej txheem nyuaj siv cov txheej txheem txhaj tshuaj molding, muaj cov rwb thaiv tsev zoo thiab huab cua tsis kam, nrog cov nqi tswj tau ntau dua, ua rau lawv tsim nyog rau kev lag luam rhiab rau qhov hnyav thiab tus nqi.
Cov ntaub ntawv tiv tauj yog qhov tseem ceeb rau tus neeg siv kev paub txog kev tactile thiab kev nyab xeeb kev noj qab haus huv. Common fabrics include high-density breathable mesh, skin-friendly synthetic leather, and antibacterial coated fabrics. Breathable mesh yog tsim los ntawm kev sib xyaw ntawm polyester lossis nylon fibers, nrog cov pores sib npaug ntawm cov fibers, txo hws buildup thiab ua kom tus neeg hnav kom qhuav thaum lub sijhawm sib cuag. Synthetic tawv siv cov txheej txheem polyurethane los simulate kev ntxhib los mos ntawm cov tawv tiag tiag, sib txuas softness thiab yooj yim tu; qhov saum npoo tuaj yeem kho tau los tiv thaiv stains, txo cov txij nkawm txhua hnub. Rau cov pej xeem los yog sib koom ib puag ncig, cov tshuaj tua kab mob coated fabrics siv nyiaj ions los yog quaternary ammonium ntsev antibacterial agents tsau rau ntawm fiber ntau los tiv thaiv kab mob loj hlob thiab txhim kho kev nyiam huv.
Filling thiab cushioning cov ntaub ntawv feem ntau yog siv rau hauv lub rooj zaum, backrest, thiab armrests los txhim kho kev haum thiab kev poob siab. High-elastic polyurethane ua npuas ncauj tswj nws txoj kev txhawb nqa rau lub sijhawm ntev vim nws txoj kev ua haujlwm zoo thiab tsis tshua muaj compression; Qee cov khoom siv sib xyaw ua ke ntawm kev nco ua npuas ncauj thiab gel hais. Cov pwm qub rau lub cev kub los faib cov ntsiab lus siab, thaum lub sijhawm tom kawg siv cov theem hloov pauv cov khoom cua sov kom muab qhov txias txias rau lub caij ntuj sov.
Rau lub folding hinges thiab connectors, hnav-resistant reinforced engineering yas los yog stainless hlau shafts feem ntau yog siv los xyuas kom meej smoothness thiab stability thaum lub sij hawm siab - siv zaus thiab tiv thaiv xeb los ntawm kev cuam tshuam lub neej. Zuag qhia tag nrho, kev xaiv cov khoom siv rau cov rooj zaum folding yuav tsum ua kom muaj kev sib npaug ntawm lub zog, kev nplij siab, ua haujlwm ntev, thiab kev phooj ywg ib puag ncig. Cov nyhuv synergistic ntawm cov ntaub ntawv sib txawv tsis tsuas yog ua rau lub cev lub zog ntawm cov khoom, tab sis kuj muab kev tiv thaiv txhim khu kev qha rau ntau hom kev siv scenarios.
