Ibhotile yePlastiki yokungunda yokuvuthela umphanda wamanzi

Ingcaciso yeMveliso

Yonke iplasti yenkwenkwezi iyazingca ngokwakha izixhobo zokubumba ezikumgangatho ophezulu zokuvuthela kwizicelo ezahlukeneyo. Iplastiki yokuvuthela imibhobho yeplastiki yenye yezona mveliso zethu zidumileyo.

Iinkcukacha zeNkqubo

Kukho iindlela ezintathu apho iimveliso zeplastiki ezibunjiweyo zinokuthi ziveliswe: ukubumba i-extrusion blow, ukubumba ukuvuthela ngesitofu, kunye nokubumba ukuvuthela. Zonke ezi nkqubo ziquka amanyathelo ambalwa nje aphambili, ahluka kakhulu kwizigaba zokuqala. Apha ngezantsi, kwiinkcukacha ezithe vetshe, ngamanyathelo okubumba isivuthelo:

1. Inyathelo lokuqala kwinkqubo yokubumba isivuthela ibandakanya ukunyibilika kweplastiki, kwaye emva koko usebenzisa isitofu sokubumba ukwenza i-preform, okanye i-parison.

Icawe liqhekeza leplastiki elimile okwetyhubhu enomngxuma kwelinye icala elivumela umoya ocinezelweyo ukuba udlule.

I-preform, ethambileyo kwaye iyabunjwa, ityhalwa ngenqama yentsimbi kwaye yandiswe kubude obumiselweyo bemveliso.

2. I-parison okanye i-preform iye ibotshelelwe kumgodi wokungunda. Ubume bokugqibela beplastiki ebunjiweyo buxhomekeke kubume bomgodi wokungunda.

3. Uxinzelelo lomoya lwaziswa ngaphakathi kwi-parison nge-blow pin. Uxinzelelo lomoya lubangela ukuba i-parison ikhule njengebhaluni kwaye ithathe ngokupheleleyo imilo yomgodi wokungunda.

4. Imveliso yokugqibela inokupholiswa mhlawumbi ngamanzi abandayo ngokusebenzisa isikhunta, ngokuqhuba, okanye ngokukhupha ulwelo olungahambelaniyo phakathi kwesikhongozeli. Inkqubo yokubumba ithatha imizuzwana embalwa; oomatshini bokubumba ukuvuthela bayakwazi ukuvelisa ukuya kuthi ga kwiikhonteyina ezingama-20,000 ngeyure.

5. Emva kokuba inxalenye yeplastiki ipholile kwaye iqiniswe, isikhunta sivula kwaye sivumele inxalenye ukuba ikhutshwe.
