Kayendetsedwe ka Ntchito ndi Chitukuko cha Zida Zapulasitiki Pamagalimoto Atsopano Amagetsi

Pakalipano, pansi pa mfundo yaikulu yachitukuko yapadziko lonse lapansi yotsindika njira ya "carbon double", kupulumutsa, kubiriwira ndi kubwezeretsanso kwakhala njira yachitukuko ya zipangizo zatsopano zamagalimoto ndi matekinoloje atsopano, ndipo zopepuka, zobiriwira ndi zobwezeretsanso zakhala chitukuko chachikulu cha magalimoto atsopano. zipangizo.Motsogozedwa ndi kuchuluka kwa magalimoto opepuka, zida zapulasitiki zakhala zikugwiritsidwa ntchito kwambiri pantchito yamagalimoto chifukwa chakuchepetsa kwawo kulemera kwawo.Kaya ndi mbali zokongoletsa kunja kwa galimotoyo, zokongoletsa mkati mwazitsulo monga chida, chitseko, chida chothandizira, chivundikiro cha bokosi la glove, mpando, mbale yoyang'anira kumbuyo, kapena ntchito ndi mawonekedwe, mutha kuwona mthunzi wa pulasitiki paliponse.Makamaka pakali pano, magalimoto amphamvu atsopano akhala akuwongolera kwambiri pakusintha ndi chitukuko cha makampani opanga magalimoto padziko lonse lapansi.Kupepuka kwa magalimoto atsopano amphamvu ndikofunikira kwambiri kuposa magalimoto achikhalidwe.Kukula kwa zida zapulasitiki kwakulitsidwa kukhala chipolopolo chatsopano cha batri yamagetsi ndi zida zina.Nthawi yomweyo, kuwotcha kwamoto, kuteteza zachilengedwe, kukana zikande, gloss kwambiri, kukana dzimbiri ndi ntchito zina zamapulasitiki zamagalimoto zimadzetsanso zovuta.

Kugwiritsa ntchito zida zingapo zamapulasitiki zomwe zimagwiritsidwa ntchito pamagalimoto

PA

Polyamide PA imadziwika kuti Nylon.Zabwino kwambiri zamakina, zolimba, zopondereza komanso kukana kuvala.PA6, PA66, wowonjezera moto woyaka moto PA6 amagwiritsidwa ntchito mu injini zamagalimoto ndi zida zotumphukira za injini, chivundikiro cha injini, chivundikiro cha injini yochepetsera, chivundikiro chamutu cha silinda, fyuluta yamafuta, chopukuta, radiator grille, ndi zina zambiri.

PA66

PA66 idapezedwa ndi polycondensation ya adipic acid ndi hexandiamine pamlingo wa molar wa 1: 1.Adipic acid nthawi zambiri amapangidwa ndi hydrogenation wa benzene koyera ndi okosijeni ndi nitric acid.PA66 imatha kukhalabe ndi mphamvu zolimba komanso kuuma pa kutentha kwakukulu;PA66 ili ndi mphamvu zamakina apamwamba, kukana kupsinjika kwabwino, ndipo ndi nayiloni yabwino kwambiri yokana kuvala;PA66 kudzikonda lubricating kwambiri, chachiwiri kwa PTFE ndi polyformaldehyde;PA66 ili ndi katundu wabwino wotentha ndipo ndi chinthu chozimitsa chokha, koma kuyamwa kwake m'madzi ndi kwakukulu, kotero kukhazikika kwake kumakhala kosauka.

PA6+GF30

PA6 GF30 ndi zotsatira za kusinthidwa kwa PA6.PA6 GF30 imawonjezera zinthu zakuthupi powonjezera ulusi wagalasi.Ulusi wagalasi womwewo uli ndi kukana kutentha, kukana moto, kukana dzimbiri, kutsekereza kutentha, kulimba kwamphamvu kwambiri komanso kutsekemera kwamagetsi kwabwino.Pambuyo kulimbikitsidwa ndi galasi CHIKWANGWANI, PA6 GF30 mankhwala akhoza kukwaniritsa zofunikira pa ntchito mafakitale ndi tsiku ndi tsiku, ndipo ali ndi makhalidwe a mphamvu kwambiri, kukana kutentha, kukana zotsatira ndi kukhazikika dimensional.

PMMA+ASA

PMMA, yomwe imadziwika kuti "plexiglass".Imakhala ndi ma transmittance abwino, makina amakina komanso kukana kukalamba komanso kukana nyengo.Koma brittleness yake ndi yokwera, yosavuta kusweka, kukana kwake ndikovuta.

ASA, yofanana ndi mawonekedwe a ABS, imagwiritsa ntchito mphira wa acrylic wopanda zomangira ziwiri m'malo mwa mphira wa butadiene mu ABS.Imasinthasintha kwambiri, imalimbana bwino ndi nyengo, komanso imalimbana bwino ndi dzimbiri.Koma pamwamba kuuma kwake si mkulu, zikande kukana, kuvala kukana si zabwino.

ABS

ABS ndi acrylonitrile - butadiene - styrene copolymer, ndi zosunthika kwambiri thermoplastic zomangamanga pulasitiki, kukana kwake, kukana kutentha, otsika kutentha kukana, kukana mankhwala ndi katundu kwambiri magetsi, komanso ali processing zosavuta ndi mankhwala kukhazikika bwino kukula, pamwamba gloss, makamaka ntchito galimoto zoziziritsa mpweya tuyere, lophimba, mbali zida mozungulira, amaundana chitetezo mbale, zogwirira chitseko, bulaketi, gudumu chivundikirocho, chonyezimira nyumba, chotetezera chitetezo chogwirira, etc.

PC/ABS aloyi

PC/ABS (P acrylonitrile – butadiene – styrene copolymer alloy) : ubwino wa PC ndi wovuta komanso wovuta, choyipa ndi kupsinjika maganizo, kukhuthala;Ubwino wa ABS ndi wabwino fluidity, koma otsika pamwamba kuuma;Mwanjira iyi, zinthu zosakanikirana za P / ABS zimasunga zabwino zonse ziwiri;PC/ABS ili ndi kuuma kwapamwamba kwambiri, kulimba kwambiri komanso kulimba, komanso kukana kupsinjika kwakukulu;Zochita zake zamakina zili pakati.PC / ABS alloy mu dashboard yamagalimoto, chogwirira chitseko, bulaketi, chiwongolero chowongolera, mbale yokongoletsera, zida zowongolera mpweya, chivundikiro chagalimoto, chipolopolo chowonetsera, nyali ya mchira ndi malo ena ambiri amagwiritsidwa ntchito.

Kukula kwamtsogolo kwa mapulasitiki agalimoto

Kuchulukitsa kwa ogula pamagalimoto osagwiritsa ntchito mafuta, olimba komanso opepuka kudzalimbikitsa kufunikira kwa mapulasitiki mumsika wamagalimoto.Mwa mapulasitiki omwe amagwiritsidwa ntchito m'galimoto, kugwiritsa ntchito mapulasitiki wamba (monga PP, PE, PVC, ABS, ndi zina zotero) kumakhala pafupifupi 60%, pomwe kuchuluka kwa mapulasitiki auinjiniya (monga PA, PC, PBT, etc.) ) amawerengera pafupifupi 18%.Chifukwa chake, pamagalimoto amakono, kaya ndi zokongoletsera zamkati, zokongoletsera zakunja, kapena mawonekedwe agalimoto, magawo ambiri ayamba kugwiritsa ntchito zida zapulasitiki m'malo mwa zitsulo, ndiko kuti, gawo lagalimoto la "pulasitiki m'malo mwake. zachitsulo” zomwe zikuchitika.
