Peb lub tuam txhab tau tsim nyob rau xyoo 2007 thiab tau cog lus rau kev tshawb fawb thiab kev tsim kho, tsim khoom, thiab muag khoom ntawm polyurethane txij thaum nws tsim. Cov khoom tseem ceeb uas tsim muaj xws li polyurethane log, polyurethane sieves, polyurethane cua kav, polyurethane boards, thiab lwm yam khoom. Tom qab ze li ntawm 20 xyoo ntawm txoj kev loj hlob, peb muaj ib pab pawg neeg muaj zog, pab neeg tsim khoom, thiab pab pawg muag khoom. Peb muaj cov cuab yeej siv ntau lawm thiab cov cuab yeej kuaj xyuas kom ntseeg tau tias qhov kev xav tau zoo ntawm txhua qhov txuas hauv cov txheej txheem ntawm polyurethane kho ntawm aluminium core log. Koj tuaj yeem tuaj xyuas lub Hoobkas txhua lub sijhawm.
Vim li cas cov txheej txheem ntawm polyurethane tread ntawm aluminium core log ntau "xav tau"?
Cov laj thawj tseem ceeb nyob hauv cov khoom siv ntawm aluminium thiab qhov siab dua qhov xav tau thaum lub sijhawm tsim khoom:
1.Higher thermal expansion thiab thermal conductivity - Txhuas muaj coefficient ntawm thermal expansion ntau dua cam khwb cia hlau thiab conducts tshav kub sai. Thaum lub sij hawm polyurethane casting (uas feem ntau tshwm sim ntawm qhov kub siab), yog tias qhov kub sib txawv ntawm cov pwm thiab cov tub ntxhais aluminium tsis nruj tswj, cov tub ntxhais aluminium yog qhov ua rau me me thermal distortion. Qhov no tuaj yeem ua rau muaj qhov tsis raug ntawm qhov khoom kawg. Tsis tas li ntawd, kev tswj qhov kub thiab txias tsis zoo tuaj yeem ua rau cov cua nkag los yog cov pa hauv pwm, ua rau muaj npuas nyob rau hauv txheej polyurethane.
2.Ntau qhov kev npaj ua kom nruj dua - Txhawm rau ua kom muaj kev ruaj ntseg adhesion, aluminium cores xav tau kev kho kom zoo dua thiab zoo ib yam, xws li precision blasting, tsim kom muaj qhov zoo tshaj plaws roughness rau kev sib txuas. Qhov no yog qhov tseem ceeb tshaj rau cov hlau cam khwb cia, qhov chaw tseem ceeb yog tshem tawm cov roj, xeb, thiab ua tiav cov roughness.
3.Kev cia siab ntau dua ntawm kev sib txuas tshuaj - Txhuas thiab polyurethane ib txwm tsim cov tshuaj tiv thaiv muaj zog dua, yog li cov txheej txheem qhia txog kev ua kom cov tshuaj adhesion los ntawm kev tu kom huv, blasting, thiab kev siv cov primers tshwj xeeb lossis cov nplaum. Nyob rau hauv sib piv, cam khwb cia hlau cores feem ntau nyob ntawm seb mechanical interlocking nta (xws li, qhov los yog grooves) raws li ib tug thaub qab los tiv thaiv delamination nyob rau hauv heev loads, ua rau cov tshuaj sib tov yuav tsum me ntsis tseem ceeb heev.
4.Tighter txheej txheem tswj - Aluminium core ntau lawm xav tau ntau yam pwm kub tswj, zoo pwm tsim (tshwj xeeb tshaj yog rau venting), thiab ntau sophisticated cua sov tshuab los tiv thaiv ob qho tib si deformation thiab npuas tsim. Cov cam khwb cia hlau cores, los ntawm kev sib piv, yog ua tiav siv cov khoom siv thiab cov txheej txheem ntau dua, nrog tsawg dua qhov tshwj xeeb.
Nyob rau hauv luv luv, thaum polyurethane tread ntawm aluminium core log thiab cam khwb cia hlau tub ntxhais PU log cia siab rau adhesion, aluminium cores xav kom nruj thermal thiab nto txheej txheem tswj kom paub meej cov khoom zoo thiab qhov ntev stability, ua rau lawv cov ntau lawm ho "finicky" dua li cov cam khwb cia hlau cores.
