Chomera cha Hyundai Motor Company cha Ulsan chidzagwiritsa ntchito foam ya BASF ya Elastoflex polyurethane popanga mipando yamagalimoto.Foam yotanuka kwambiri ya polyurethane iyi imakhala ndi VOC yotsika ndipo imagwiritsidwa ntchito makamaka popanga mipando yamagalimoto ndi zopumira.Poyerekeza ndi thovu lachikhalidwe,Elastoflex imapangitsa chitonthozo, kusungunuka komanso katundu wonyamula mipando ndi zopumira.Pofuna kukwaniritsa malamulo okhwima kwambiri oletsa kutulutsa mpweya, BASF yakonzanso njira zopangira ma polyether polyols.Ma polyether polyols amagwiritsidwa ntchito popanga thovu la Elastoflex polyurethane, lomwe limagwiritsidwa ntchito popangamipando yapamwamba.Kapangidwe kameneka kamathandizira BASF kupanga ma polyether polyols apadera otsika mtengo, magwiridwe antchito apamwamba komanso kutsika kwa VOC.M'mayeso opangidwa ndi bungwe loyesa kwambiri padziko lonse lapansi la SGSKorea, Elastoflex idachepetsa mpweya wa acetaldehyde ndi formaldehyde ndi 30%, kuthandiza kukonza mpweya wabwino wamgalimoto komanso thanzi la oyendetsa magalimoto.Mayesero am'munda awonetsanso kuti mawonekedwe a polyurethane omwe angopangidwa kumene ali ndi mphamvu zoyenda bwino komanso kutsika kwachilema kwa zinthu, zomwe zimapangitsa kuti mzere wopanga ukhale wabwino.
Zida zatsopano zili ndi ubwino wamphamvu.Popanga magalimoto, mipando yamagalimoto imakhala pamalo akulu, omwe amatsimikizira mwachindunji kuchuluka kwa zida zomwe zimagwiritsidwa ntchito.Magalimoto amakhudza pang'onopang'ono moyo wa anthu ndikupangitsa kuyenda kwa anthu kukhala kosavuta.Mipando yamagalimoto yachikhalidwe nthawi zambiri imakhala yachikopa, ndipo ambiri amapangidwa ndi siponji ndi zinthu zina, zomwe zilibe chitonthozo.Masiku ano, mapulasitiki a thovu a polyurethane osinthika Monga chimodzi mwazinthu zopangira mipando yamagalimoto, ndi apamwamba kwambiri komanso otsika mtengo, ndipo pang'onopang'ono amagwiritsidwa ntchito ndi opanga kupanga magalimoto ambiri.“Polyurethane thovu ndi mtundu wa zinthu zatsopano zofewa komanso zotanuka.Lili ndi pores ambiri, kachulukidwe chokha, kulimba mtima bwino, mayamwidwe phokoso, mpweya, zabwino matenthedwe kutchinjiriza ndi zina.Amagwiritsidwa ntchito m'mbali zonse za moyo.opanga ambiri kusankha High-elastic polyurethane thovu ntchito ngati chuma mipando galimoto, ndi ntchito za nkhaniyi pang'onopang'ono amavomerezedwa ndi anthu.
Thestatic chitonthozo champando wamagalimotoamatanthauza ngati ubale wofananira pakati pa mpando wagalimoto ndi thupi la munthu ukhoza kupangitsa ogwiritsa ntchito kukhala omasuka.Chitonthozo chokhazikika cha mpando chikugwirizana ndi magawo a kukula, chithandizo chapamwamba ndi makhalidwe osinthika a mpando.Zomwe zimapangidwira pampando nthawi zambiri zimakhala za thovu zokhala ndi kusungunuka kwambiri komanso kutsika kochepa, zomwe zingalepheretse zinthuzo kuti zisawotchedwe.Masiku ano, boma la China lili ndi zofunikira kwambiri pazida zamagalimoto, zomwe zimafuna kuti mtengo woyaka kwambiri ukhale ≤70mm/min.Malamulo oterowo amawonjezera chitetezo cha galimoto yokha, ndipo chithovu chosinthika cha polyurethane ndi muyezo woyaka uwu chimagwiritsidwa ntchito.Kuchita zishalo kumawonekeranso pang'onopang'ono m'munda wa masomphenya a opanga.Kukana kuvala kwa thovu losinthika la polyurethane kumagwiritsidwa ntchito ngati zopangira mipando yamagalimoto.Kusalimba kwazinthu zambiri zamapulasitiki kumapangitsa kuti zikhale zosatheka kugwiritsa ntchito kwa nthawi yayitali, koma thovu losinthika la polyurethane limakana kuvala bwino.Ili ndi mphamvu zolimba zolimba komanso kukana misozi, zomwe zimapangitsa kukhala ndi magwiridwe antchito apamwamba.Poyerekeza ndi mipando ya galimoto yachikhalidwe, mtengo wake ndi wotsika, nthawi yogwiritsira ntchito ndi yaitali, ndipo pulasitiki yake ndi yolimba.okondedwa ndi opanga.
Kukula kwamakampani opanga thovu a polyurethane sikungasiyanitsidwe ndikusintha kwamphamvu yopanga.Monga chimodzi mwazinthu zisanu ndi chimodzi zazikulu zopangira padziko lapansi zomwe zimakopa chidwi kwambiri, kukula kwa mafakitale a thovu a polyurethane kwakula kwambiri m'zaka zaposachedwa.Malinga ndi "2016-2022 China Polyurethane Industry Market Trend Forecast and Trend Forecast Research Report" yotulutsidwa ndi Booz Data: kutulutsa kwapadziko lonse kwa zinthu za polyurethane kwadutsa matani 21 miliyoni, omwe machitidwe a thovu ndi zinthu zopanda thovu zimatengera theka lililonse. ya dziko, ndipo kukula kwake kwakukulu kumakonzedwa kuti zisawonongeke.Mchitidwe wa kachulukidwe kake ndi wodziwikiratu Popanga, makampani a polyurethane, monga mafakitale ambiri amankhwala, ali ndi chizolowezi chodziwikiratu chakukula komanso kukula.Pamene luso la kupanga polyurethane likukulirakulira, malonda akukhala otchuka kwambiri ndipo minda yogwiritsira ntchito ikupitirira kukula, opanga apeza kuti kuti apitirize kukhala ndi phindu linalake, ayenera kukhala ndi chuma china cha scale. mabizinesi atsopano akukulirakulira, ndipo mphamvu zopanga zikuchulukiranso mwachangu.Kuvomereza kwa ogula sikukudziwikabe, ndipo pali zambiri zoti ziwongoleredwe.Monga tafotokozera pamwambapa, thovu la polyurethane lapamwamba kwambiri ndi mtundu watsopano wa zinthu, ndipo anthu sanayambebe kumvetsa mozama za makhalidwe ake, kotero sipanakhalepo chidziwitso chachikulu cha msika.Chifukwa chakuti galimotoyo ndi yogwirizana kwambiri ndi miyoyo ya anthu itagulidwa, ndipo chifukwa cha mtengo wake wokwera, mabanja ambiri sangalowe m’malo mwa galimotoyo kwa nthawi yaitali ataigula.Kuwunika mawonekedwe ake osiyanasiyana, mpando wopangidwa ndi thovu la polyurethane wosinthika pang'onopang'ono ukhala chimodzi mwazinthu zomwe anthu amaziganizira.
Poyerekeza ndi mipando yachikhalidwe, mipando yopangidwa ndi thovu yatsopano yosinthika ya polyurethane imakhala ndi zokayikitsa zambiri.Choncho, sichinakhale chinthu choyenera kukhala nacho m'maganizo a ogula.Choyamba, zochita za mankhwala a "polyurethane thovu" palokha.Pambuyo pa chithovu chosinthika cha polyurethane chimapangidwa kukhala mpando wa galimoto, chifukwa cha kuwala kwa dzuwa kwa nthawi yaitali, mpweya wa galimoto umakhala wokwera kwambiri, ndipo kutentha mkati mwa galimotoyo kudzakhala kokwera kwambiri.Kuchita ndi kutulutsa mpweya wapoizoni kungawononge kwambiri chitetezo cha moyo wa madalaivala.Malinga ndi zotsatira za kafukufuku wofunikira, kuchuluka kwa siloxane kumalowetsamo zinthu zambiri zamagalimoto zomwe zamalizidwa panthawi yopanga, ndipo zida zake sizingatulutse mwachindunji zinthu zapoizoni, koma munjira ina ya volatilization, siloxane imamwazika pang'onopang'ono mu thovu losinthika la polyurethane. mpando wagalimoto, kumapangitsa kusinthasintha kwa thovu losinthika la polyurethane, ndikupanga mpweya wapoizoni.Chifukwa chake, ndikofunikira kukonza izi mwachangu ndikuchepetsa ntchito yake. Kuphatikiza apo, malinga ndi zofunikira za ergonomic, mpando wagalimoto uyenera kupangidwa ngati chinthu chokhala ndi malo opindika, omwe ndi ovuta kukwaniritsa chifukwa cha thovu lamtundu wa bokosi. ndondomeko ya "polyurethane thovu".Choncho, kokha akamaumba thobvu ndondomeko angagwiritsidwe ntchito panopa., pamlingo wina wake amaletsa kukula kwa "high elastic polyurethane thovu".Monga tonse tikudziwira, m'chilimwe, dzuwa limawalira mwachindunji mkati mwa galimoto.Chifukwa cha kusindikizidwa bwino kwa galimotoyo, zidzachititsa kutentha kwambiri m'galimoto.Ngati chithovucho ndi chapoizoni, kutentha kwakukulu ndi kutsekemera kwa mpweya mkati mwa galimoto kumayambitsa poizoni wa anthu omwe ali m'galimoto.Pa nthawi yomweyi, ngati chithovucho chili ndi zinthu zambiri zamoyo, ngati chimasungunuka ndi kutentha kutentha kwambiri, zinthu zambiri zamoyo zimagwedezeka pa galasi pamwamba pa galimoto, zomwe zidzakhudza kwambiri masomphenya a dalaivala ndi chifukwa. ngozi zapamsewu.Choncho, kumvetsetsa bwino ntchito ya mtundu uwu wa thovu kumafunika , Ndi njira iyi yokha yomwe nkhaniyi ingagwiritsidwe ntchito bwino, kuvomerezedwa pang'onopang'ono ndi madalaivala ndikuvomerezedwa ndi ogula ambiri.Malinga ndi chidziwitso cha ogula ndi maphunziro ndi ndemanga zoipa, pali njira yotalikirapo kuti thovu la polyurethane lapamwamba kwambiri likhale lokhazikika pamipando yamagalimoto amtsogolo.
Koma m'kupita kwa nthawi, ngakhale thovu lapamwamba la polyurethane lokha lili ndi zolakwika zina, ubwino wake ndi wofunika kwambiri.Ndikukhulupirira kuti posachedwapa, ndi kusintha kwa msinkhu wa sayansi ndi luso la anthu, zofooka za thovu la polyurethane zosinthika zidzagonjetsedwa Kamodzi, luso la kupanga magalimoto ndi chitetezo cha galimoto zakhala zikuyenda bwino.Pokhapokha pamene thovu lolimba la polyurethane lidzakhala ndi mwayi wokhala pamipando yamtsogolo yamagalimoto.
