PU ua npuas ncauj log siv polyurethane ua npuas ncauj ua cov khoom siv log tsheb thiab tau siv dav hauv tsheb thauj khoom, tsheb thauj khoom, tsheb trolleys, khoom siv logistics, thiab lwm yam kev tuav tes. Tsis zoo li cov pa pneumatic thiab cov khoom siv roj hmab, PU ua npuas lub log cia siab rau cov qauv ntawm cov cellular ntawm polyurethane ua npuas ncauj los muab kev txhawb nqa thiab cushioning. Qhov no tso cai rau lawv los ua ke qhov hnyav qis nrog kev ua haujlwm ruaj khov thiab kev poob siab.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub log PU ua npuas ncauj yog ua raws li tus cwj pwm elastic ntawm nws cov khoom siv ntawm tes. Thaum muaj kev thauj khoom, lub log yog compressed ntawm cov khoom siv thiab hauv pem teb. Cov npuas dej muaj ib lub network ntawm cov hlwb me me uas deform nyob rau hauv siab, tso cai rau lub zog thov kom muab faib thoob plaws hauv lub log. Thaum lub load raug txo, cov khoom yuav maj mam rov qab mus rau nws cov qauv qub, muab kev txhawb nqa elastic txuas ntxiv thaum lub sijhawm ua haujlwm.
Thaum cov cuab yeej txav mus, qhov chaw sib cuag ntawm lub log thiab hauv pem teb raug tswj kom deformation. Thaum lub log hla dhau cov pob qij txha hauv pem teb, cov teeb meem me me, lossis qhov me me ntawm qhov tsis sib xws, cov polyurethane ua npuas dej muaj peev xwm nqus tau ib feem ntawm qhov cuam tshuam los ntawm deformation. Qhov no pab txo cov kev co xa mus rau cov khoom siv thiab nws cov load, ua rau kom smoother zog piv nrog rau ib co nruj log designs.
Rolling cwj pwm yog lwm qhov tseem ceeb ntawm lub log kev ua haujlwm. Raws li tus neeg teb xov tooj thawb cov khoom siv, lub log tig ib ncig ntawm nws lub qag thaum lub PU npuas tread tseem nyob rau hauv kev sib cuag nrog hauv pem teb. Material density, hardness, wheel diameter, and tire construction all influence rolling resistance. Los ntawm kev ua kom zoo dua cov yam ntxwv no, cov tuam txhab tsim khoom tuaj yeem ua tiav qhov tsim nyog sib npaug ntawm lub peev xwm thauj khoom, maneuverability, cushioning, thiab yooj yim ntawm kev txav.
PU ua npuas ncauj log kuj muaj kev tiv thaiv zoo rau kev sib tsoo- cuam tshuam txog kev ua tsis tiav thiab cov kev xav tau nyiaj txiag niaj hnub. Vim hais tias lub log tsis nyob ntawm cov pa cua chamber, nws tsis tas yuav muaj kev nce nqi thiab tsis tuaj yeem poob nws cov yam ntxwv ntawm kev txhawb nqa yooj yim vim yog lub tiaj tus - teeb meem log tsheb. Qhov no ua rau PU ua npuas ncauj log yog qhov kev xaiv zoo rau warehouses, factories, tis centres, thiab lwm qhov chaw uas cov cuab yeej txav tau ntau zaus.
Zuag qhia tag nrho, PU ua npuas ncauj log ua haujlwm los ntawm elastic deformation, thauj khoom faib, thiab cov yam ntxwv zoo ntawm polyurethane ua npuas ncauj. Factors such as foam density, hardness, wheel diameter, tire construction, and wheel-center design all influence the final performance. Ua raws li cov yam ntxwv no rau daim ntawv thov tuaj yeem muab qhov sib npaug ntawm kev txhawb nqa, cushioning, hnav tsis kam, thiab maneuverability, ua PU ua npuas ncauj log yog ib qho kev daws teeb meem rau cov khoom siv tuav.
