Mkhalidwe Wogwiritsira Ntchito ndi Chiyembekezo cha Ukadaulo Wa Foaming mu Automobile Wiring Harness

M'zaka zaposachedwa, bizinesi yamagalimoto yaku China yakula mwachangu, ndipo polyurethane, imodzi mwazinthu zopangira polima, imagwiritsidwa ntchito mochulukira m'zigawo zamagalimoto.

M'zinthu zamagalimoto zopangira ma wiring, ntchito yayikulu ya groove yowongolera ma waya ndikuwonetsetsa kuti ma waya amatetezedwa bwino ndikukhazikika ku thupi mumalo ang'onoang'ono komanso osasinthika agalimoto.M'malo omwe kutentha kumakhala kocheperako, monga malo okwera anthu, gwiritsani ntchito pulasitiki yolemera kwambiri ngati chiwongolero cha zingwe.M'madera ovuta monga kutentha kwakukulu ndi kugwedezeka, monga zipinda za injini, zipangizo zokhala ndi kutentha kwakukulu, monga galasi fiber reinforced nayiloni, ziyenera kusankhidwa.
Ma waya amtundu wa injini amatetezedwa ndi machubu a malata, ndipo ma waya omwe amamalizidwa ndi mapangidwe awa ali ndi mawonekedwe otsika mtengo, osavuta komanso osinthika.Komabe, mphamvu yolimbana ndi dzimbiri komanso kuwononga waya yomalizidwa ndi yoperewera, makamaka fumbi, mafuta, ndi zina zotero zimatha kulowa mosavuta muzitsulo za waya.
Chingwe chawaya chomalizidwa ndi kuumba thovu la polyurethane chili ndi chitsogozo chabwino ndipo ndichosavuta kuyika.Wogwira ntchitoyo amangofunika kutsatira njira yopangira ndi njira atatenga waya, ndipo akhoza kuikidwa mu sitepe imodzi, ndipo sikophweka kulakwitsa.Chingwe cholumikizira mawaya opangidwa ndi polyurethane chili ndi mawonekedwe ambiri apamwamba kuposa ma waya wamba, monga kukana mafuta, kukana fumbi lamphamvu, ndipo palibe phokoso pambuyo poyika ma waya, ndipo amatha kupangidwa mosiyanasiyana mosiyanasiyana malinga ndi malo athupi.

Komabe, chifukwa mawaya opangira ma waya opangidwa ndi nkhaniyi amafunikira ndalama zambiri pazida zokhazikika koyambirira, opanga ma waya ambiri sanatengere njira iyi, komanso magalimoto ochepa apamwamba monga Mercedes-Benz ndi Audi ma wiring harnesses. amagwiritsidwa ntchito.Komabe, pamene kuchuluka kwa dongosololi ndi kwakukulu komanso kosasunthika, ngati mtengo wapakati ndi kukhazikika kwabwino ziyenera kuwerengedwa, ndiye kuti mtundu uwu wa waya uli ndi mwayi wopikisana nawo.

Outlook
Poyerekeza ndi chikhalidwe jekeseni akamaumba ndondomeko, RIM polyurethane zipangizo ndi njira ndi ubwino wa otsika mphamvu mowa, kulemera kuwala, njira yosavuta, otsika nkhungu ndi kupanga ndalama, etc. Magalimoto amakono apangidwa kuti akwaniritse zofunikira za chitonthozo chapamwamba, ndipo ntchito zawo zikukhala zambiri ndi zovuta.Zigawo zambiri ziyenera kukhala mumlengalenga, kotero kuti malo otsala a waya amakhala ochepa komanso osakhazikika.Mitundu ya jekeseni yachikhalidwe imakhala yoletsedwa kwambiri pankhaniyi, pomwe mawonekedwe a nkhungu ya polyurethane amakhala osinthika.
Reinforced Reaction Injection Molding (RRIM) ndi mtundu watsopano waukadaulo wopangira jakisoni womwe umapanga zinthu zokhala ndi makina abwinoko poyika zodzaza ndi ma fiber monga ulusi wagalasi mu nkhungu yoyaka moto.
Kugwiritsa ntchito zida za polyurethane zomwe zilipo komanso zida zogwirira ntchito zofufuzira paukadaulo wa polyurethane zitha kukulitsa njira zopangira zinthu ndikuwongolera magwiridwe antchito.M'tsogolomu, ukadaulo uyenera kuyambitsidwa mozama kwambiri popanga ma wiring harness grooves owongolera magalimoto.Pamapeto pake zimathandizira mabizinesi kukwaniritsa cholinga chochepetsera ndalama ndikukweza mpikisano wamsika.
