Kutengera njira yopangira,zotchinga madziZingagawidwe m'magulu awiri: zotchingira madzi zozungulira ndi zotchingira madzi zozungulira. Ponena za kalembedwe, zotchingira madzi zitha kugawidwanso m'magulu asanu: zotchingira madzi zozungulira, zotchingira madzi zokhala ndi mabowo awiri, zotchingira madzi zokhala ndi mabowo atatu, zotchingira madzi zozungulira, zotchingira madzi zazitali, ndi zotchingira madzi zozungulira. Kutengera ndi njira yopangira ndi kalembedwe, zotchingira madzi zitha kugawidwa makamaka m'zotchingira madzi zozungulira ndi zotchingira madzi zozungulira, ndipo mitundu yawo imasiyana.
Kusiyana pakati pa Rotomolding ndi Blow Molding Water Filled Barriers
Zotchinga zamadzi zopangidwa ndi rotomoldedAmapangidwa pogwiritsa ntchito njira yozungulira ndipo amapangidwa kuchokera ku pulasitiki ya polyethylene (PE) yomwe imalowetsedwa kunja. Ali ndi mitundu yowala komanso yolimba. Koma zotchingira madzi zopangidwa ndi mpweya, zimagwiritsa ntchito njira yosiyana. Zonsezi pamodzi zimatchedwa zotchingira madzi zapulasitiki zoyendera ndipo zimapezeka pamsika.
Kusiyana kwa Zinthu Zopangira: Zotchingira madzi zopangidwa ndi rotamoldous zimapangidwa ndi zinthu zopangidwa ndi PE zomwe sizili zogulitsidwa kunja konse, pomwe zotchingira madzi zopangidwa ndi rotamoldous ...
Kusiyana kwa Kulemera: Zotchinga zamadzi zopangidwa ndi roto-molded zimakhala zolemera kwambiri kuposa zomwe zimapangidwa ndi blow-molded, ndipo zimalemera kuposa gawo limodzi mwa magawo atatu. Mukamagula, ganizirani kulemera kwa chinthucho ndi mtundu wake.
Kusiyana kwa Kukhuthala kwa Khoma: Kukhuthala kwa mkati mwa khoma la zotchingira madzi zopangidwa ndi roto nthawi zambiri kumakhala pakati pa 4-5mm, pomwe kwa zotchingira madzi zopangidwa ndi blow-mold ndi 2-3mm yokha. Izi sizimangokhudza kulemera ndi mtengo wa zinthu zopangira zotchingira madzi zopangidwa ndi blow-mold, komanso chofunika kwambiri, zimachepetsa kukana kwawo kugwedezeka.
Moyo Wotumikira: Pansi pa mikhalidwe yofanana yachilengedwe, zotchingira madzi zopangidwa ndi roto nthawi zambiri zimakhala zaka zoposa zitatu, pomwe zotchingira madzi zopangidwa ndi roto zimatha kukhala miyezi itatu kapena isanu yokha zisanasinthe, kusweka, kapena kutuluka madzi. Chifukwa chake, kuchokera pamalingaliro anthawi yayitali, zotchingira madzi zopangidwa ndi roto zimapereka phindu lalikulu pamtengo.
Kuumba kwa Roto kumadziwikanso kuti rotational molding kapena rotational casting. Kuumba kwa Rotomolding ndi njira yopangira hollow-molding thermoplastics. Chida chopangidwa ndi ufa kapena chopangidwa ndi ufa chimalowetsedwa mu nkhungu. Nkhunguyo imatenthedwa ndikuzunguliridwa molunjika komanso mopingasa, zomwe zimathandiza kuti zinthuzo zizitha kudzaza bwino dzenje la nkhungu ndikusungunuka chifukwa cha mphamvu yokoka ndi mphamvu ya centrifugal. Pambuyo pozizira, chinthucho chimachotsedwa kuti chikhale chopanda kanthu. Chifukwa liwiro lozungulira la rotomolding ndi lochepa, chinthucho sichimapanikizika ndipo sichimakhudzidwa ndi kusintha, kusweka, ndi zolakwika zina. Pamwamba pa chinthucho ndi lathyathyathya, losalala, komanso lowala bwino.
Kuumba blow molding ndi njira yopangira zigawo zopanda kanthu za thermoplastic. Njira youmba blow molding ili ndi magawo asanu: 1. Kutulutsa pulasitiki preform (chubu cha pulasitiki chopanda kanthu); 2. Kutseka ma flaps a nkhungu pamwamba pa preform, kumamatira nkhungu, ndikudula preform; 3. Kudzaza preform pakhoma lozizira la nkhungu, kusintha kutsegula ndikusunga kupanikizika panthawi yozizira; kutsegula nkhungu ndikuchotsa gawo lophulika; 5. Kudula flash kuti apange chinthu chomalizidwa. Mitundu yosiyanasiyana ya thermoplastics imagwiritsidwa ntchito poumba blow molding. Zipangizo zopangira zimapangidwa kuti zikwaniritse zofunikira zogwirira ntchito komanso magwiridwe antchito a chinthu chopangidwa blow-mold. Zipangizo zopangira blow-mold-grade ndi zambiri, ndipo polyethylene, polypropylene, polyvinyl chloride, ndi thermoplastic polyester ndizomwe zimagwiritsidwa ntchito kwambiri. Zobwezerezedwanso, zochotsedwa, kapena zophwanyidwanso zimatha kusakanikirana.
Magawo aukadaulo a Zotchinga Madzi
Kulemera Kodzazidwa: 250kg/500kg
Mphamvu Yokoka: 16.445MPa
Mphamvu Yokhudza Mphamvu: 20kJ/cm²
Kutalika pa nthawi yopuma: 264%
Malangizo Okhazikitsa ndi Kugwiritsa Ntchito
1. Yopangidwa kuchokera ku polyethylene yolunjika (PE) yochokera kunja, yosamalira chilengedwe, ndi yolimba komanso yobwezerezedwanso.
2. Yokongola, yosatha, komanso yosavuta kugwiritsa ntchito pamodzi, imapereka chenjezo lalikulu komanso imachepetsa chiopsezo cha ngozi.
3. Mitundu yowala imapereka chizindikiro chomveka bwino cha njira ndipo imakongoletsa misewu kapena mizinda.
4. Popeza zili ndi dzenje komanso madzi, zimapereka mphamvu zotetezera, zimathandiza kunyamula mphamvu zambiri komanso kuchepetsa kuwonongeka kwa magalimoto ndi antchito.
5. Yopangidwa kuti ikhale yolimba komanso yokhazikika.
6. Yosavuta komanso yachangu: anthu awiri akhoza kuyiyika ndikuchotsa, kuchotsa kufunikira kwa crane, ndikusunga ndalama zoyendera.
7. Amagwiritsidwa ntchito popewera ndi kuteteza anthu m'malo odzaza anthu, zomwe zimachepetsa kupezeka kwa apolisi.
8. Kuteteza malo a misewu popanda kufunikira kumangidwa kwa misewu.
9. Ikhoza kuyikidwa m'mizere yowongoka kapena yokhota kuti ikhale yosinthasintha komanso yosavuta kugwiritsa ntchito.
10. Yoyenera kugwiritsidwa ntchito pamsewu uliwonse, pamalo olumikizirana magalimoto, malo oimika magalimoto, mapulojekiti omanga, komanso m'malo omwe anthu ambiri kapena ang'onoang'ono amasonkhana, zomwe zimagawa misewu bwino.
