Makhalidwe a rotational akamaumba ndondomeko

Njira yozungulira yozungulira imadziwikanso kuti kuumba kwa rotary, kuponyera kozungulira.Ndi njira yopangira dzenje ya thermoplastic.
Kumangirira kozungulira ndi njira yopangira zinthu zambiri popanga zida zapulasitiki zopanda kanthu.Njira yozungulira yozungulira imagwiritsa ntchito kutentha ndi kuzungulira pamodzi ndi nkhwangwa ziwiri kuti apange mbali imodzi.Pulasitiki yosungunuka imalowetsedwa mu nkhungu yozungulira, ndipo mphamvu ya centrifugal imakakamiza pulasitiki yosungunuka kumamatira ku khoma lamkati la nkhungu.
Ndiko kuti, ufa kapena phala zinthu jekeseni mu nkhungu poyamba, ndipo zinthu wogawana yokutidwa ndi nkhungu patsekeke ndi kusungunuka ndi mphamvu yokoka ndi centrifugal mphamvu yake mwa kutentha nkhungu ndi kugudubuza ndi mozungulira mu ofukula ndi yopingasa malangizo. , ndiyeno demoulded kupeza dzenje mankhwala pambuyo kuzirala.Chifukwa liwiro lozungulira la kuumba kozungulira silokwera, zidazo ndizosavuta, mankhwalawa amakhala opanda nkhawa yamkati, ndipo sizovuta kufota ndi kugwedezeka.Poyamba, izo zinali makamaka ntchito PVC phala kupanga pulasitiki zidole, mipira mphira, mabotolo ndi mankhwala ena ang'onoang'ono.Posachedwapa, amagwiritsidwanso ntchito kwambiri pazinthu zazikulu.Ma resins omwe amagwiritsidwa ntchito ndi polyamide, polyethylene, modified polystyrene polycarbonate, etc.
Ndizofanana ndi kuponyera kozungulira, koma zomwe zimagwiritsidwa ntchito si zamadzimadzi, koma ufa wouma wouma.Njirayi ndikuyika ufawo mu nkhungu ndikuupangitsa kuti uzungulira kuzungulira nkhwangwa ziwiri zosiyana.Chomeracho chikhoza kupezedwa kuchokera ku nkhungu potenthetsa ndi kusakaniza mofanana pakhoma lamkati la nkhungu, ndiyeno kuziziritsa.
Kumatchedwanso rotary molding kapena rotary molding.Pulasitiki yaufa (monga LLDPE) imawonjezeredwa ku nkhungu yotsekedwa.Nkhungu imatenthedwa pamene ikuzungulira.Pulasitiki imasungunuka ndikumamatira pamwamba pa nkhungu mofanana.Pambuyo nkhungu utakhazikika, pulasitiki dzenje zopangidwa ndi mawonekedwe ofanana ndi nkhungu patsekeke akhoza analandira, monga mabwato, mabokosi, migolo, beseni, zitini, etc. Nthawi zambiri imakhala kudyetsa, nkhungu kusindikiza, Kutentha, kuzirala, demoulding, kuyeretsa nkhungu ndi njira zina zofunika.Njirayi ili ndi ubwino wa shrinkage yaying'ono, kuwongolera kosavuta kwa makulidwe a khoma ndi mtengo wotsika wa nkhungu, koma kutsika kwachangu.

Zofunikira zazikulu za njira yozungulira yozungulira ndi izi:

1.Mtengo wa nkhungu yozungulira ndi yotsika - pazinthu zofanana, mtengo wa nkhungu yozungulira ndi pafupifupi 1 / 3 mpaka 1 / 4 ya kuwombera ndi jekeseni, yomwe ili yoyenera kuumba zinthu zazikulu zapulasitiki.

2.Rotational akamaumba mankhwala m'mphepete mphamvu zabwino - akamaumba rotational akhoza kukwaniritsa mankhwala m'mphepete makulidwe oposa 5 mm, kuthetsa vuto la dzenje mankhwala m'mphepete woonda.

3.Rotational akamaumba akhoza kuika inlays zosiyanasiyana.

4.Mawonekedwe a zinthu zozungulira zozungulira akhoza kukhala ovuta kwambiri, ndipo makulidwe amatha kukhala oposa 5 mm.

5.Rotational akamaumba akhoza kupanga zinthu zotsekedwa kwathunthu.

6.Rotational akamaumba mankhwala akhoza kudzazidwa ndi thovu zipangizo kukwaniritsa kusungunula matenthedwe.

7.Kulemera kwa khoma la zinthu zozungulira zozungulira zimatha kusinthidwa momasuka (kuposa 2mm) popanda kusintha nkhungu.
