Isikhunta Sebhodlela Lepulasitiki Lokuvuthela Umgqomo Wamanzi

Incazelo Yomkhiqizo

I-All star plast iyaziqhenya ngokwakha amathuluzi esikhunta sekhwalithi ephezulu yezinhlelo zokusebenza ezahlukahlukene. Isikhunta sepulasitiki semiphongolo singenye yemikhiqizo yethu ethandwa kakhulu.

Imininingwane Yenqubo

Kunezindlela ezintathu lapho imikhiqizo yepulasitiki ebunjiwe ingakhiqizwa: i-extrusion blow molding, i-injection blow blowing, kanye ne-stretch blow molding. Zonke lezi zinqubo ziqukethe izinyathelo ezimbalwa eziyinhloko, ezihluka kakhulu ezigabeni zokuqala. Ngezansi, ngokuningiliziwe, izinyathelo zokubumba i-blow:

1. Isinyathelo sokuqala enqubweni yokubumba igalelo sihlanganisa ukuncibilika kwepulasitiki, bese usebenzisa ukubumba komjovo ukulenza libe i-preform, noma i-parson.

Isonto ucezu lwepulasitiki olumise okweshubhu elinembobo engxenyeni eyodwa evumela umoya ocindezelwe ukuba udlule.

I-preform, ethambile futhi ebumbayo, iphushwa inqama yensimbi futhi inwetshwe ekuphakameni okunqunyiwe komkhiqizo.

2. I-parison noma i-preform ibe isiboshelwa emgodini wesikhunta. Ukuma kokugcina kwepulasitiki ebunjiwe kuncike ekumeni kwesikhunta.

3. Umfutho womoya ungeniswa ngaphakathi kwesonto ngephini lokushaywa. Umfutho womoya ubangela i-parison ukuthi inwebe njengebhaluni futhi ithathe ngokugcwele ukuma kwesikhunta.

4. Umkhiqizo wokugcina ungapholiswa ngokugeleza kwamanzi abandayo ngesikhunta, ngokuqhutshwa, noma ngokuhwamulisa uketshezi olungaguquki esitsheni. Inqubo yokubumba igalelo ithatha imizuzwana embalwa; imishini yokubumba i-blow iyakwazi ukukhiqiza iziqukathi ezingafika ku-20,000 ngehora.

5. Uma ingxenye yepulasitiki isipholile futhi iqinile, isikhunta siyavuleka futhi sivumele ingxenye ukuba ikhishwe.
