Mavuto ndi zothetsera zomwe zimayambitsidwa ndi khoma lopyapyala la bumper yagalimoto

Bumper yagalimoto ndi imodzi mwazinthu zazikulu pagalimoto, ili ndi ntchito zitatu zazikulu: chitetezo, magwiridwe antchito ndi zokongoletsera.
Pali njira zitatu zazikuluzikulu zamagalimoto zopepuka zopepuka: zopepuka zakuthupi, kapangidwe kake kakukhathamiritsa komanso kupanga njira zatsopano zopangira.Zinthu zopepuka zopepuka zimatanthawuza kusintha zinthu zoyambira pansi pamikhalidwe ina, monga pulasitiki yachitsulo;mawonekedwe okhathamiritsa opepuka kwambiri amakhala ndi ukadaulo wapakhoma woonda;njira yatsopano yopangira zinthu imakhala ndi thovu laling'ono laling'ono komanso makina othandizira gasi ndi matekinoloje ena atsopano.
Pulasitiki yosankha zinthu zapulasitiki chifukwa cha kuwala, ntchito yabwino, kupanga kosavuta, kukana kwa dzimbiri, kukana kwamphamvu, ufulu wamapangidwe ndi mawonekedwe ena, imagwiritsidwa ntchito kwambiri pamafakitale amagalimoto, komanso kuchuluka kwazinthu zambiri zamagalimoto.Kuchuluka kwa pulasitiki yogwiritsidwa ntchito pagalimoto yakhala imodzi mwa njira zoyezera kukula kwa makampani opanga magalimoto m'dziko.Pakalipano, mayiko otukuka kupanga galimoto yogwiritsira ntchito pulasitiki yafika 200kg, zomwe zimawerengera pafupifupi 20% ya khalidwe la galimotoyo.
Pulasitiki mumakampani amagalimoto aku China ndikugwiritsa ntchito mochedwa, kuchuluka kwa pulasitiki m'magalimoto azachuma ndi 50 ~ 60kg, magalimoto akuluakulu ali ndi 60 ~ 80kg, magalimoto ena amatha kufika 100kg, China popanga magalimoto apakati, galimoto iliyonse yokhala ndi pafupifupi 50kg ya pulasitiki.Galimoto iliyonse imagwiritsa ntchito pulasitiki pa 5 mpaka 10 peresenti ya kulemera kwa galimotoyo.
Zida za bumper nthawi zambiri zimakhala ndi izi: kukana kukhudzidwa bwino, kukana kwanyengo yabwino.Kuthekera kwa penti yabwino, madzi abwino, ntchito yabwino yopangira, mtengo wotsika.Chifukwa chake, zida zamakalasi a PP mosakayikira ndizosankha zabwinoko zotsika mtengo.PP zakuthupi ndi mtundu wa pulasitiki wamba wokhala ndi magwiridwe antchito abwino, koma PP yokha imakhala ndi kutentha kochepa kochepa komanso kukana, osavala kukana, kukalamba kosavuta komanso kusakhazikika bwino, kotero PP yosinthidwa nthawi zambiri imagwiritsidwa ntchito ngati zida zopangira galimoto.Pakadali pano, zida zamagalimoto za polypropylene zapadera nthawi zambiri zimakhala PP ngati chinthu chachikulu, ndikuwonjezera gawo lina la mphira kapena elastomer, zodzaza ndi inorganic, tinthu tating'onoting'ono ta amayi, zowonjezera ndi zida zina zitasakanizidwa ndikukonzedwa.

N'zosavuta kuyambitsa warping deformation, zomwe ndi zotsatira za kumasulidwa kwamkati mkati.Mabampa okhala ndi mipanda yopyapyala amayambitsa kupsinjika kwamkati mu magawo osiyanasiyana a jekeseni.
Nthawi zambiri, zimaphatikizanso kupsinjika kwamalingaliro, kupsinjika kwamatenthedwe komanso kupsinjika kwa nkhungu.Kupanikizika kwapang'onopang'ono ndi kukopa kwamkati komwe kumachitika chifukwa cha ulusi, unyolo wa macromolecular kapena magawo a unyolo mu melt omwe amayang'ana mbali inayake ndipo amayamba chifukwa cha kupumula kosakwanira.Kuzungulira kwake kumakhudzana ndi makulidwe azinthu, kutentha kwasungunuka, kutentha kwa nkhungu, kuthamanga kwa jakisoni, ndi nthawi yosungira mphamvu.Kukwera kwa makulidwe, kutsika kwake komwe kumalowera;kumtunda kwa kutentha kwa sungunuka, kutsika kwa malo, kutsika kwa malo;kukwera kwamphamvu kwa jekeseni, kumakwera kwambiri;Kutalikirapo kwa nthawi yosungirako kupanikizika, ndikokulirapo kwambiri.
Kupsyinjika kwamafuta ndi chifukwa cha kutentha kwa kutentha kwa nkhungu ndi kutentha kwapansi kwa nkhungu, komanso kuzizira kofulumira kwa kusungunuka m'deralo pafupi ndi nkhungu.Kupsyinjika kumasulidwa makamaka chifukwa cha mphamvu zosakwanira ndi kuuma kwa nkhungu, kusinthika kwa zotanuka pansi pa mphamvu ya jekeseni ndi kutulutsa pamwamba, ndi kugawa kosayenera kwa mankhwala osokoneza bongo.Khoma lopyapyala kwambiri lingakhalenso lovuta.Chifukwa chakuti makulidwe a khoma ndi ang'onoang'ono ndipo ali ndi shrinkage yaying'ono, mankhwalawa amamatira mwamphamvu ku nkhungu;kukakamiza kugwira nthawi kulamulira kumakhala kovuta, ndipo makulidwe a khoma laling'ono ndi kulimbikitsa zimawonongeka mosavuta.Kutsegula kwachibadwa kwa nkhungu kumafuna syringe kuti ipereke mphamvu yokwanira yotsegula nkhungu, yomwe iyenera kuthana ndi kukana kutsegula nkhungu.

Pali zopinga zingapo zomwe ziyenera kugonjetsedwa potsegula nkhungu

Choyamba, ndikofunikira kuthana ndi mphamvu yotsegulira mwachindunji.Pamene nkhungu imatsegulidwa, pulasitiki idzakhala ndi mphamvu yomatira yofanana ndi njira yotsegulira, yomwe imakhala chifukwa cha kuzizira kwa zigawo za pulasitiki pamene kuzizira kwa nkhungu sikukwanira, ndipo kufalikira kwamtundu wamtundu sikunapezeke bwino.Kukula kwa mphamvu yomatira iyi kumagwirizana ndi chikhalidwe cha pulasitiki, mawonekedwe apamwamba a nkhungu, malo otsetsereka a nkhungu, ndi zina zotero. core m'zigawo ndondomeko.M'pofunikanso kugonjetsa kukaniza kukangana chifukwa cha kayendedwe ka nkhungu kusuntha template ndi ntchito template.Ndiye m'pofunika kugonjetsa nawo kuthamanga kwa patsekeke, pamene kuthamanga kwa patsekeke sangakhale wofanana ndi mpweya mumlengalenga, ndi kuthamanga mu patsekeke si wofanana ndi kuthamanga kunja.
Kuti athetse mavuto akuluakulu awiriwa, mapangidwe a nkhungu ayenera kukonzedwa moyenera.Sankhani zinthu zoyenera nkhungu kuti muwongolere mphamvu yamatenthedwe a nkhungu ndi kukana.Kupanga koyenera kwa nkhungu ndi kupanga, moyenerera kuonjezera makulidwe a mbale yokankhira ndi mbale yapakatikati, kuwongolera kuuma kwa nkhungu, kuchepetsa kusinthika kwa nkhungu.Limbikitsani kupanga ndi kugwirizanitsa kulondola kwa makina oyambira ndi kayendedwe ka kayendetsedwe kake, kuchepetsa kuuma kwamtundu wamtundu wamtundu, zigawo zapakati ndi ma convex module, ndikuchepetsa mphamvu yotulutsa nkhungu.Ndi mapangidwe apamwamba komanso kufananitsa koyenera, chipangizo cholumikizira nthawi zambiri chimaperekedwa kuti chiteteze kusamutsidwa kwapakatikati ndi kufa.Dongosolo lothira liyenera kupangidwa bwino, ndipo mawonekedwe a njira yoyendetsera ayenera kugwiritsa ntchito kwambiri zigawo zapulasitiki kuchokera kumadera okhuthala kupita kumalo owonda kwambiri panthawi yobaya.Padzafunikanso kukhala ndi madoko okwanira otulutsa mpweya.Pankhani ya jekeseni, kupsinjika kwa mkati mwa zigawo za pulasitiki kuyenera kuchepetsedwa, ndipo liwiro la jekeseni ndi liwiro lozizira liyenera kuchepetsedwa.Kuonjezera kutentha kwa kusungunuka ndi kutentha kwa nkhungu ndikofunikira kuti muchepetse.Kupanikizika koyenera kwa jekeseni, nthawi yosungira mphamvu, ndi nthawi yozizira zimafunikanso.Huangyan Leiao Molding Co., Ltd. ili mumzinda wa Huangyan District mold, Taizhou, chigawo cha Taizhou, chomwe ndi "Tauni yaku China mold".Kampaniyi imagwira ntchito kwambiri pakupanga nkhungu ya jekeseni, ili ndi zaka zambiri za nkhungu, makamaka kupanga ndi kukonza nkhungu ya botolo, nkhungu ya PET, nkhungu ya botolo, mkati mwa galimoto ndi nkhungu yokongoletsera kunja… … nkhungu dongosolo ali ndi mapangidwe ake apadera ndi processing luso, zochokera lingaliro la "Umphumphu kasamalidwe", ndi makasitomala zoweta ndi akunja kukhazikitsa ubale wabwino wa nthawi yaitali mgwirizano, ndikukhulupirira kuti Leiao adzakhala oyenera chikhulupiriro chanu mu cooperative bizinesi.
