Zokhudza makina otulutsira zinthu: Msika wotsatira wa madola trilioni wa zipangizo zopepuka, msika wa zipangizo za EPP ukupitilira kukula

Makina a ExtrusionPolypropylene Yowonjezera (EPP) ndi chinthu choteteza kutentha komanso choteteza kutentha chomwe chili ndi chitetezo cha chilengedwe chopanda poizoni, mphamvu zambiri, kulimba bwino, kutchinjiriza bwino komanso zabwino zina, mitundu ya ntchito yomwe ilipo pano ndi yayikulu kwambiri, m'magalimoto, zomangamanga, zida zapakhomo, ma CD ndi zina zimagwiritsidwa ntchito kwambiri, kufunikira kwa msika ndikokwera.



01 Kodi zinthu za EPP n'chiyani?
Monga chinthu chobiriwira chotetezera kutentha, EPP ikufunika kwambiri popanga mabokosi otengera zinthu; kuwonjezera pa izi, EPP ikufunika kwambiri m'magalimoto chifukwa cha kusawononga poizoni, kukana mafuta, kukana kutentha komanso kukana kugwedezeka, ndipo ingagwiritsidwe ntchito m'mabampala, zophimba dzuwa, mawilo owongolera, mipando yotetezeka ndi madera ena, zomwe zimapangitsa kuti ikhale chinthu chofunikira kwambiri mumakampani opanga magalimoto.
Kutengera njira yopangira thovu ya EPP, EPP ikhoza kugawidwa m'magulu awiri: EPP yosakanikirana, EPP yolumikizidwa ndi EPP yowonjezereka, ndipo EPP yowonjezereka ndiyo njira yopangira chifukwa cha njira yosavuta komanso magwiridwe antchito apamwamba.

Kupanga kwa EPP kuli ndi zopinga zambiri zaukadaulo, ndipo pakadali pano pali mabizinesi ochepa am'nyumba omwe angapange EPP. Kukula kwa kupanga kwapakhomo ndi pafupifupi matani 45,000 pachaka, ndipo mabizinesi oyimira kupanga ndi Shanghai Zhongtong, Wuxi Huitong ndi Suzhou Delong. Padziko lonse lapansi, mphamvu yopanga ya EPP ndi pafupifupi matani 160,000 pachaka, ndipo JSP ndiye kampani yotsogola.

Komabe, mu Marichi 2021, JSP Corporation, kampani yayikulu kwambiri padziko lonse lapansi yogulitsa zinthu zopangira EPP, idachotsa fakitale yake ya Chongqing ku China ndikuchepetsa mphamvu yake yopangira chifukwa cha zotsatira zoyipa za msika wogwiritsa ntchito; mu Seputembala 2022, Hanhua Group, kampani yayikulu kwambiri yogulitsa zinthu zopangira EPP ku South Korea, idalengezanso kuti yachoka pantchito zonse zokhudzana ndi EPP ku China.

Zipangizo za EPP 02 zili ndi ntchito zambiri
Monga thovu lobiriwira komanso lopanda chilengedwe, EPP pakadali pano imagwiritsidwa ntchito kwambiri popaka, zoseweretsa ndi magalimoto, ndipo kufunikira kwakukulu kwa magalimoto.

M'zaka zaposachedwapa, pamene kupanga ndi kugulitsa magalimoto kukupitirira kukwera, kufunikira kwa mapulogalamu a EPP kwakula ndipo makampani akukula mofulumira. Ponena za kupanga, chifukwa cha kuchuluka kwaukadaulo wopanga EPP, pakadali pano pali makampani ochepa opanga ndipo msika uli wokhazikika kwambiri. Ponseponse, ngakhale kuti EPP ili ndi mitundu yosiyanasiyana ya mapulogalamu, malo amsika ndi ochepa, ndipo msika uli wokhazikika kwambiri, kotero pali malo ochepa oti makampani apitirire patsogolo mtsogolo.

Zigawo zamagalimoto za EPP zomwe zimakhala ndi zotsatira zomwezo zonyamula mphamvu kuti zifike pamlingo wofanana ndi wa thovu la polyurethane lopepuka kuposa 40%-50%, pomwe pakati pa bampala yagalimoto, zishango zam'mbali, zoteteza mawondo, mafupa a mipando ndi zina zotero nthawi zambiri zimafunika kuti zikhale ndi mphamvu yabwino komanso zotsutsana ndi kuwomba, komanso zimafuna kulemera kochepa kwa pakati. Izi zimapangitsa thovu la polypropylene kukhala njira ina m'malo mwa thovu la polyurethane mu nsanja yochepetsera mphamvu zamagalimoto.

Kuwonjezera pa kulemera kwake kopepuka, thovu la polypropylene ndi lothandiza kwambiri kuposa thovu la polyethylene ndi polystyrene pamapulatifomu omwe amafunikira kutentha kwakukulu kogwirira ntchito, monga zophimba dzuwa, mapanelo oteteza zida ndi madera omwe kutentha pakati pa zitseko kungakwere.

Koma kuwonjezera pa nsanja zamagetsi ndi zoyamwa kutentha, thovu la polypropylene lilinso ndi kuthekera kotenthetsera kutentha, zomwe zapangitsa kuti pakhale ntchito zambiri zopangira thovu la polypropylene m'malo oimika magalimoto, zitseko, denga la galimoto, zipangizo zothandizira makapeti, mapanelo oteteza mawu, zitseko ndi malo osungira katundu.

Makhalidwe ake abwino opangira kutentha apangitsanso kuti pakhale ntchito zambiri m'zigawo monga mabokosi akuluakulu ndi zoziziritsa kukhosi. Kuphatikiza apo, thovu la polypropylene lingagwiritsidwenso ntchito popanga mawilo oyendetsera, mapanelo amkati mwa zitseko, zoteteza mphamvu, ma cushioning pads, zopumira mutu, mabokosi a zinthu, ma cushion, mapanelo a zida, ndi zina zotero.

Popeza thovu la polypropylene limawonongeka mosavuta kuposa thovu la polystyrene, thovu la polyurethane ndi thovu la polyethylene, n'kosavuta kusintha zinthu zina zonse ndi thovu la polypropylene chifukwa cha kudziwa bwino maboma apadziko lonse lapansi za kuteteza chilengedwe.

Zikuoneka kuti chifukwa cha chitukuko cha thovu la polypropylene, padzakhala chitukuko chochulukirapo pakugwiritsa ntchito kwake m'magalimoto.

03 EPP ikugwiritsidwa ntchito pa nsanja yayikulu komanso yayikulu

Zinthu za IT, zida zamagetsi zolumikizirana, zowonetsera zamakristalo amadzimadzi, ma TV amtundu wa plasma, zida zamagetsi zolondola, zida zolondola ndi zoyezera zonse zikuyamba kulandira EPP ngati zinthu zopakira zambiri.

Njira ina yogwiritsira ntchito kwambiri ndi kuchuluka kwa ntchito zomwe zimagwiritsidwa ntchito m'makampani opanga magalimoto: mabampala a magalimoto, ma cores oteteza mbali ya galimoto, ma cores oteteza zitseko za galimoto, mipando yachitetezo cha akuluakulu, mipando yachitetezo cha ana, ma trunk, malo opumulira manja, ma pads apansi, ma visor a dzuwa, ma dashboard, ndi zina zotero. (malinga ndi ziwerengero: pakadali pano, galimoto iliyonse imafanana ndi pulasitiki ya 100-130kg pogwiritsa ntchito pulasitiki ya EPP ya 4-6kg).

Kuphatikiza apo, EPP ndi chinthu chabwino kwambiri chopangira zinyalala za ndege koma mtengo wake ndi wochepa, zinyalala za ndege za EPP ndi chifukwa chachikulu.

Kugwira ntchito kwa zinthu za Epp kuti zithandizire kugwiritsidwa ntchito kwake m'mbali zonse za moyo, koma mtengo wake ukuchepetsa kukula kwa gawo lake la kugwiritsidwa ntchito, kotero kugwiritsidwa ntchito kwamakono kuli m'mafakitale ena ovuta kwambiri, chifukwa chogwiritsidwa ntchito kwambiri, ukadaulo wopanga zinthu za EPP ukhoza kudikira kuti uwonjezere ndikuchepetsa ndalama pambuyo pozikwaniritsa.

Zipangizo za Epp zitha kusinthidwa m'njira zosiyanasiyana kuti zikwaniritse zosowa za mafakitale osiyanasiyana. Vutoli likhoza kukhala mtengo wokwera, womwe umachepetsa kugwiritsidwa ntchito kwake kwakukulu, koma chifukwa cha kupita patsogolo kwa ukadaulo, akukhulupirira kuti zipangizo za EPP zidzagwiritsidwa ntchito m'mafakitale ambiri, zomwe zidzakhudza kwambiri kuteteza chilengedwe ndi kugwiritsa ntchito zinthu.
