Cov tuam txhab tuam txhab tau paub txog qhov kom zoo dua ntawm kev tso cov ntaub qhwv: Sijhawm txuag thiab zoo. Hauv txoj kev hwm no lawv tuaj yeem siv rau ntau txoj haujlwm. Lawv tuaj yeem pom nyob hauv cov ntaub thaiv npog hauv qab, qhov rooj-linings, headliners raws li zoo li lub suab nqus ua npuas ncauj. Automotive cov khoom muag txuag lub sijhawm thaum chaw tsim khoom nrog nteg clims thiab tau ruaj khov rau lawv cov feem. Muab ob daim ntawv tsaj muag rau kev kho vaj tse- thiab lub suab nqus tau nruab nrog cov ntaub qhwv.
Puas yog koj tab tom nrhiav rau lub clim uas tseem tuaj yeem ua haujlwm hauv tshav kub khaus? Los yog cov khawb av uas yog dej tsis kam? Koj puas xav tau cov ntawv sau uas ua rau txhua hnub ua haujlwm yooj yim? Los yog cov khawb av uas ua kom zoo dua koj cov txheej txheem ntau lawm? Koj puas xav kom muaj kev sib tw ntawm decomposable ntuj fibers lossis ntev ntev kawg-tech fiber ntau? Los yog? Los yog?
Peb tuaj yeem tsim kev ua ke ua ke zoo meej rau koj daim ntawv thov.
Automotive: Kev txhawb nqa rau lub suab nqus cov ntsiab lus
Cov tsheb tuam txhab siv lub suab nqus cov khoom kom muaj cov suab nrov txo ntawm lawv cov tsheb. Cov ntsiab no feem ntau yog ua los ntawm hnyav foamed plastics / polyurethane (pur) nyuaj ua npuas, bitumen lossis cov khoom sib xyaw.
Lawv feem ntau tau sib sau ua ke lossis thov rau hauv cov chaw uas cia tsuas yog ib qho kev tsim kho tsis tshua muaj, xws li hauv qab hood / bonnet lossis hauv qab headliner. Qee qhov chaw no tsuas yog nkag tau rau hauv cov txheej txheem mounting (piv txwv ntawm vaj huam sib luag ntawm lub rooj zaum thiab lub qhov rai iav dov / cua muag). Vam khom los ntawm cov qib zoo ntawm lub tsheb, cov ntsiab lus nqus lub suab kuj tseem siv:
- Hauv a-, c-, thiab (hauv chaw nres tsheb wagons / combi vans) d-ncej
- Hauv cov pob tw npog / khau raj
- Hauv cov chaw sab hauv ntawm wings / Fenders
- Hauv kev cais ntawm Dashboard thiab cav Bay / compartment (pem hauv ntej cav) lossis nruab nrab ntawm (rov qab) rooj thiab nram qab
- Ntawm cov ntaub pua plag thiab chassis
- Ntawm kis tau qhov
Xav tau cov kev phiv los ntawm cov suab yuav nqus cov suab yog qhov damping ntawm lub tsheb lub cev deeg thiab yog kev cais tawm tsam kub thiab txias. Qhov no ua rau lub suab rwb thaiv tsev moulding tseem nyob hauv lub cev thiab caravans.
Rau ib daim ntawv siab tshaj plaws ruaj khov thiab kev nqus dej tsis muaj kev xav tau cov qauv kev ua haujlwm. Automotive - engineers cia siab rau nteg cov khawb av kom ua kom lub suab tiv thaiv kev tiv thaiv kev tiv thaiv kev cuam tshuam:
- Deformation
- Shear rog
- Swb / hloov tawm ntawm txoj haujlwm
- Kev khi
- Kev sib txhuam / puas
- Yam muaj
Kev txhawb nqa rau cov txee tom qab, Headliners, kev tiv thaiv kev cuam tshuam
Muab cov khawb av kuj tseem siv los txhawb cov headiners thiab rhawv nraub qaum. Ntawm no yog qhia ntau txog kev nce daim ntawv ruaj khov thiab tergional rigidity. Lwm thaj chaw ntawm daim ntawv thov yog cov neeg cuam tshuam tiv thaiv mats los tiv thaiv cov qhov rooj tsheb hauv qhov chaw nqaim.
Dab tsi yog pw scrims?
Muab cov khawb av yog lub teeb yuag lub teeb ua los ntawm cov xov paj / cov ntaub ntawv uas txawv uas txawv ntawm cov ntaub zoo li:
- Cov xov tsis pw xoob thiab hauv qab ib leeg. Nrog rau "binder" lawv yog glued nyob tas li ntawm lawv cov ntsiab lus sib cuag.
- Xov khiav Diagonally / multi-axial nyob rau hauv6 txog 10 cov lus qhiaCov. Yog li lawv nqus ua haujlwm ua haujlwm ntau dua zoo dua.
- Lawv hloov tau yooj yim dua thiab ib txhij ntau dua ruaj khov.
- Lawv cov txheej txheem siab dua thaum lub zog ua lub zog tso cai rau cov kab mob hnyav thiab qhov hnyav qis dua ib thaj chaw.
- Koj tuaj yeem ua ntau txoj kev xaiv ntawm cov ntaub ntawv, muab txiaj ntsig ntawm lawv cov yam ntxwv tshwj xeeb.
- Cov xov ntawm Scrim tuaj yeem nruab nrog cov neeg coob coob tuaj yeem txhawb nqa cov ntaub ntawv tshwj xeeb ntawm cov khoom kawg.
Kev haum rau cov txheej txheem ntau lawm
Txhua thib ob ntawm lub tsheb cov txheej txheem siv nyiaj. Nrog nteg clims cov neeg muab khoom ntawm kev lag luam hauv tsheb txuag kom txuag tau lub sijhawm hauv kev sib dhos ntawm lawv cov khoom. Koj muaj 3 txoj kev xaiv los ua peb cov khaubncaws sab nraud povtseg:
- Raws li txheej hauv multi-txheej cov khoom lag luam
- Gluing ntawm cov chaw sib chwv (piv txwv li lub cev panels)
- Raws li ib qho keeb ntawm ob-lub ntsej muag nplaum nplaum
Peb cov khoom siv tso cov khawb hauv coiled dav - ntawm kev thov kom muaj sijhawm xwb. Nrog lawv qhov zoo heev cuttability thiab punchability lawv pab kom lub siab tsim kom zoo thiab kev ua haujlwm siab. Yog li lawv tsim nyog rau kev ua cov kev ua haujlwm ua haujlwm zoo li rau automated xuas nrig ntaus cov kab.
