Kuwotcha tsitsi ndi njira imodzi yokhakupanga zinthu zopanda pakendi mpweya kuthamanga kuwomba ndi kutupa otentha Sungunulani mazira otsekedwa mu nkhungu.The dzenje nkhonya akamaumba ndi extrude ku extruder ndi kuika tubular thermoplastic akusowekapo amene akadali kufewetsa boma mu akamaumba nkhungu. Kenako kupyolera wothinikizidwa mpweya, ntchito mpweya kuthamanga kwa deform akusowekapo pamodzi kufa patsekeke, motero kuwomba mu khosi lalifupi dzenje mankhwala.
Hollow blowing molding ndiye ukadaulo wofunikira kwambiri popanga zinthu zapulasitiki zopanda kanthu.Pafupifupi thermoplastics onse angagwiritsidwe ntchito akamaumba dzenje kuwomba, monga polyethylene, PVC, polypropylene, polystyrene, liniya poliyesitala, polycarbonate, polyamide, mapadi acetate ndi poly acid formaldehyde utomoni, etc.
Ndi luso akamaumba, izo sizingakhoze kokhapanga yaying'ono kuchulukamabotolo angapo milliliters, komanso akhozapangazikwi za malita achachikulu - voliyumumigolo ndi matanki osungira madzi, komanso mipira yoyandama, matanki amafuta amgalimoto ndi kayak.
Kodi zopangira zowombeza ziyenera kukhala ndi zotani?
1.Environmental stress akulimbana kukana: monga chidebe, amatha kuteteza kusweka akakumana ndi surfactant;
2.Kuthina kwa mpweya (kukana permeability): kutanthauza zinthu zomwe zimalepheretsa kufalikira kwa mpweya, mpweya woipa, nayitrogeni ndi nthunzi wamadzi.
3.Kukana kugwedezeka: Pofuna kuteteza katundu m'chidebecho, zinthuzo ziyenera kukhala ndi mphamvu zowonongeka zomwe sizingawonongeke kuchokera kutalika kwa mita imodzi.
4.Kuphatikiza apo, pali kukana kwa mankhwala, kukana kwa static, kulimba ndi kukana extrusion.
Ubwino wowombeza ndi wotani?
1.Hollow, kapangidwe ka mipanda iwiri imatha kuyamwa ndikuchotsa mphamvu zomwe zimakhudzidwa;
2.Flexible design, yokhala ndi ntchito zambiri komanso mtengo wotsika mtengo;
3.The luso processing akhoza kusintha makulidwe a mluza;
4.During processing, makulidwe a mankhwala akhoza kusinthidwa mwakufuna popanda kusintha nkhungu;
5.Kuponderezedwa kwapansi (kupanikizika kwa mkati mwa nkhungu kumakhala kochepa kwambiri kusiyana ndi jekeseni wa jekeseni), kuti apititse patsogolo kukhazikika kwa dimensional, kukana kwa corrosion kwa mankhwala ndi kutentha kwakukulu;
Kusiyanasiyana kwa 6.Assembly: zomangira zodzikongoletsera, zoikamo kufa, zomangira zowonjezera za rivet;
7.Simple nkhungu, mtengo wotsika ndi yochepa processing mkombero;
8.Chitsanzo cha nkhungu chokhala ndi mtengo wotsika chingapangidwe mwamsanga.
Blow molding ndi njira yopangira momwe mapulasitiki opanda kanthu amapangidwira: Amagwiritsidwanso ntchito popanga mabotolo agalasi.Kawirikawiri, pali mitundu itatu ikuluikulu ya kuwombera:extrusion kuwomba akamaumba, jekeseni kuwomba akamaumba, ndi jekeseni kutambasula kuwomba akamaumba.
Mawonekedwe:
.Ntchito yokhazikikandi advanced PLC.
.Kutumiza preforms basindi conveyor.
.Kulowa mwamphamvundi kugawa bwino komanso mwachangu kwa kutentha polola kuti mabotolo azizungulira okha ndikuzungulira njanji nthawi imodzi mu chotenthetsera cha infrared.
.Kusintha kwakukulukupangitsa kuti chotenthetsera chizitenthetseratu ma preforms mu mawonekedwe posintha chubu chowunikira komanso kutalika kwa bolodi yowunikira m'malo otentha, komanso kutentha kwamuyaya mu preheat yokhala ndi zida zodziwikiratu za thermostatic.
.Kutetezedwa kwakukulundi zida zodzitsekera zodzitchinjiriza pamakina aliwonse, zomwe zingapangitse kuti njirazo zisinthe kukhala chitetezo pakagwa njira inayake.
Kwenikwenikuwombera mphutsindi gawo la pulasitiki lopangira dzenje ndikupanga chidebe cholumikizira mbali izi.Imapezeka m'mawonekedwe ndi makulidwe ambiri.Kuwomba ndi jekeseni ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri ndipo zimagwiritsidwa ntchito kwambiri ndi njira iyipanga zida zapulasitiki zapamwamba pamtengo wocheperakokotero iyi ndi njira yotsika mtengo kwambiri.Kuwomba ndi njira yakale yomwe imagwiritsidwa ntchito popanga zinthu zopanda kanthu.Pakuumba kwa Blow zinthu zambiri zimakhudzidwa monga "mtundu wa pulasitiki, liwiro, liwiro, kutentha.Mpweya ndi chimodzi mwazinthu zofunika kwambiri ndipo umagwira ntchito yofunika kwambiri popanga kuwomba.Mpweya umakankhidwira mu nkhungu kuti ukulitse ndikuupatsa mawonekedwe omwe akufuna.Njira yopangira kuwombera ndiyosavuta, imagwiritsidwa ntchito kwambiri ndipo imaphatikizapo makina otsika mtengo, kupanga mabotolo apulasitiki pogwiritsa ntchito njirayi ndi yotsika mtengo kwambiri poyerekeza ndi jekeseni.Popanga nkhungu sikufunika kuti apange nkhungu yolondola kwambiri.
Kubowoleza - ndi njira yodziwikiratu yopangira zomwe zida zapulasitiki zopanda kanthu zimapangidwira ndipo zimatha kulumikizidwa palimodzi.
Amakina opangira magetsiamagwiritsidwa ntchito kwambiri popanga zakumwa zamalonda.Makina opangira nkhonya amapanga botolo la pulasitiki molingana ndi Chinsinsi, mwachitsanzo kufotokoza kuchuluka kwa botolo lomwe lingapangidwe.Makinawa amakhala ndi nkhungu, zowongolera zowongolera, komanso zida zamakina ndi zamagetsi.
