Chochitika chochititsa chidwi chinapeza kuti zolumikizira zambiri zamtundu wa lalanje, zomwe zimagwiritsidwa ntchito m'magalimoto kwakanthawi, chipolopolo cha pulasitiki chidawoneka chowoneka bwino, ndipo chodabwitsa ichi sichosiyana, osati banja la chodabwitsacho, makamaka galimoto yamalonda.
Makasitomala ena adandifunsa ngati izi zimakhudza kugwiritsa ntchito kwawo. Kodi pali ngozi iliyonse? Kodi zimakhudza moyo wautumiki?
Musanayankhe funsoli, lembani mafunso angapo kuti mupeze yankho:
1. Chifukwa chiyani kuli kofunikira kugwiritsa ntchito mtundu wa lalanje pazolumikizira zamagetsi apamwamba? Kodi ndizotheka kuti musagwiritse ntchito?
2. Kodi cholumikizira nthawi zambiri chimakhala chipolopolo chapulasitiki chamtundu wanji? Kodi mtundu wa lalanje umachokera kuti?
3. Chifukwa cha kugwiritsa ntchito zochitika zapadera,? Kodi pali vuto lililonse ndikugwiritsa ntchito nthawi yayitali?
4. Kodi zimenezi zimatichititsa kuganizira chiyani ndipo tiyenera kuganizira chiyani?
Chifukwa chiyani zolumikizira ma voltage okwera amafunika kugwiritsa ntchito mtundu wa lalanje? Kodi sitingachigwiritse ntchito?
Kugwiritsiridwa ntchito kwa lalanje monga chenjezo lamtundu wamagetsi apamwamba kumaonedwa kuti ndi "zochitika zapadziko lonse", mwachitsanzo, US National Electrical Code (NEC) yatenga lalanje ngati mtundu wofunikira pazingwe zamagetsi apamwamba; kuyambira kumapeto kwa zaka za m'ma 90 pamene HEVs adadziwika pang'onopang'ono ku EVs, lalanje lakhala likugwiritsidwa ntchito ngati chizindikiro chamtundu wochenjeza za ma xEV, chomwe chimagwiritsidwa ntchito kutanthauza mawaya apamwamba kwambiri ndi zolumikizira.zingwe zamphamvu kwambiri komanso zolumikizira; kachitidwe kameneka kamene kamayang'ana kachidziwitso kamene kamasonyeza kuti ndi zigawo ziti zamagulu amphamvu kwambiri zomwe siziyenera kukhudzidwa popanda maphunziro oyenerera a chitetezo ndi zida zodzitetezera.
Kodi magetsi okwera magalimoto ndi chiyani? "Gawo la magalimoto" "high voltage concept" nthawi zambiri ndi "voltage class" B "molingana ndi tanthauzo la ISO 6469-3, nthawi zambiri imakhala ndi magetsi opangira> 60 V ndi ≤ 1500 V DC kapena 30 V ndi ≤ 1000 V AC. . > 30 V ndi ≤ 1000 V AC, malinga ndi muyezo "Zingwe zamabasi zothamanga kwambiri zomwe sizili m'nyumbamo ziyenera kudziwika ndi chivundikiro cha "lalanje" Basi, pamenepa, imatanthawuza msonkhano, yomwe ilinso ndi zolumikizira;
Pankhani ya mfundo zolumikizira, kaya ndi miyezo yayikulu ya OEM, kapena Europe idathetsedwa "miyezo ya LV" kapena miyezo yofananira ya USCAR, (LV215 216 USCAR20 SAE1742, etc.) yanena kuti cholumikizira cholumikizira chamtundu walalanje nambala yamakhadi amtundu imafotokoza zofunikira za RAL 2003, 2008 ndi 2011; yomwe RAL 2003 ndiyo yowala kwambiri, RAL 2011 imakhala yofiira komanso yakuda, ndipo RAL 2008 ili pakati. Zofunikira zimatanthauzidwa ngati RAL 2003, 2008, ndi 2011; yomwe RAL 2003 ndiyo yowala kwambiri, RAL 2011 imakhala yofiira komanso yakuda kwambiri, ndi RAL 2008 pakati pa ziwirizi, pamene lalanje imayenera kukwaniritsa mtundu wa zaka zoposa 10 popanda kusintha.
Kotero mtundu wa lalanje ndilo lamulo lofunikira la msewu, ngati lapangidwa ndi zitsulo, nthawi zambiri liyeneranso kulembedwa m'dera lodziwikiratu la chizindikiro cha chenjezo lapamwamba kwambiri, kotero simungakhale lalanje? Nthawi zambiri ayi, chifukwa malamulo okhudzana ndi chitetezo akhoza kukanidwa.
Ndi zinthu ziti zomwe zimagwiritsidwa ntchito polumikizira ndi zipolopolo zapulasitiki? Kodi mtundu wa lalanje umachokera kuti?
Zipolopolo zolumikizira nthawi zambiri zimapangidwa ndi zinthu za polyurethane, zomwe zimagwiritsidwa ntchito kwambiri PA66 PBT, etc., zipolopolo za pulasitiki zimafunika kukwaniritsa zofunikira za kutsekemera kwa dongosolo, ndipo nthawi yomweyo ziyenera kukhala ndi makhalidwe enaake, monga mphamvu zokwanira, kukana misozi. , kulimba, etc., komanso ayenera kukhala ndi makhalidwe a lawi retardant, kotero ambiri CTI mtengo ali zofunika zapadera, kawirikawiri, opanga adzagwiritsa ntchito zipangizo nayiloni kuonjezera zoyenera Kawirikawiri, opanga adzagwiritsa ntchito nayiloni zinthu ndi galasi ulusi woyenera monga ake. zinthu, monga PA66+30%GF_V0 kapena PBT.
Mtundu wa lalanje nthawi zambiri umapangidwa m'njira ziwiri, imodzi ndi tinthu tating'onoting'ono ta pulasitiki toyera, kuphatikiza pang'ono pang'ono pophatikizika ufa, nthawi zambiri ndi mtundu wanthawi zonse, mtundu womaliza umakhala wokhazikika, ndipo mtengo wofananira nawo ndi wokwera, opanga zinthu zonse ayenera kukwaniritsa zofunikira zofananira zamtundu wamtundu, monga BASF, Celanese ndi zina zotero.
Chifukwa chogwiritsa ntchito zochitika zapadera,? Kodi pali zovuta zilizonse ndi mapulogalamu a nthawi yayitali?
Vuto kumayambiriro kwa nkhani lili mu batire bokosi kunja, poyera, malo poyera ndi kuwala kwa dzuwa chaka chonse, ndi pafupi gudumu, inertia gudumu la zowononga dzimbiri kuponyedwa mmwamba peresenti inayake Ufumuyo zinthu, zochokera pa izi, choyamba, kuthekera kwa whitening ndi kwakukulu chifukwa cha nthawi yayitali yotentha ndi kutentha kwa dzuwa, kufulumizitsa liwiro la ukalamba wake, womwe umatsogolera kuyera, ndipo nthawi yomweyo, UV ndi kuwala kwina kudzayambitsidwa ndi zimachitikira mankhwala ndi zinthu pamwamba, chifukwa inapita patsogolo zinthu whitening. Panthawi imodzimodziyo, kuwala kwa ultraviolet ndi kuwala kwina kumapangitsanso kuti zinthu ziwonongeke, zomwe zimapangitsa kuti zinthu ziwonongeke komanso kuyera, kuwonjezera pakuwonekera komanso pafupi ndi galimotoyo zidzachititsa kuti ziwonongeke ndi asidi. - munali zoipitsa, zomwe zidzachititsa kuti inapita patsogolo kuwonongeka kwa zinthu mamolekyu mu asidi mothandizidwa ndi mankhwala anachita whitening.
Ponseponse, kuyera kwa zinthuzo kumatanthauza kuti pali chiwopsezo cha "embrittlement" ndi "kuwonongeka kwa zinthu zamagetsi", zomwe zingakhudze moyo wake wautumiki ndikuwonjezera mwayi wa kulephera kwazinthu poyerekeza ndi zolumikizira wamba, monga kusweka pambuyo pakukhudzidwa ndi zinthu zachilendo, monga miyala. Poyerekeza ndi zolumikizira wamba, pali mwayi wochuluka wa kulephera kwazinthu, monga kukhala wosavuta kusweka pambuyo pa kukhudzidwa kwa miyala ndi zinthu zina zakunja, kukhala ndi vuto losauka likamanyowa, komanso kukhala wosavuta kuwonongeka.
Kuti atipangitse kuganiza za zomwe tiyenera kuziganizira?
Kuchokera pamalingaliro akukula kwa zolumikizira zamphamvu kwambiri, zolumikizira zofikira ku miniaturization, kuphatikiza (zida zosavuta kuphatikiza zolumikizirana ndi magetsi) zopepuka (zophatikizika kwambiri, kukula kochepa, makulidwe owonda, ndi zina zambiri), izi ndizomwe zimapangidwira kafukufuku waukadaulo ndi zopambana zimayika patsogolo zofunikira; mwachitsanzo, malo olumikizirana osagwirizana ndi abrasion (zida zokutira, kusankha gawo lapansi, ndi kafukufuku wina) ndi zina zotero.
