Amabhulogi

Qala ukuxazulula inkinga ngokurekhoda i-alamu, imodi yokusebenza nendawo yomshini yamanje. Qhathanisa amanani asethiwe nempendulo yangempela, bese uhlola okokufaka okufanelekile, okukhiphayo nezimo ezivumelayo. Setha kabusha kuphela ngemva kokuqonda imbangela futhi indawo iphephile.

Isilawuli se-parison siyashintsha i-die-gap ngomjikelezo we-extrusion. Iphrofayili kufanele ihambisane nengxenye yejiyomethri, ukuziphatha kwe-resin, ubude be-parison, isikhathi sokushaywa, i-tooling zero ne-span, futhi—emshinini wokuhlanganisa—indawo ye-accumulator. Shintsha okuguquguqukayo okukodwa ngesikhathi futhi uqinisekise ingxenye ebunjiwe.

Umshini wokubumba umshini wamakhemikhali wokuhlanganisa izigubhu uwumshini wokuhlanganisa we-accumulator osayizi wezigubhu ezingamalitha angama-200 kuye kwangama-220. I-accumulator ikhipha i-parison esindayo ngokushesha, ngaphambi kokuba amandla adonsela phansi ayikhiphe esimweni. Konke okunye mayelana nomshini kukhona ukuze usebenze umzuzwana owodwa: ukuhlolwa kokudonsa.

Umshini wokubumba wenza imikhiqizo yepulasitiki engenalutho - amabhodlela, amathini amajeri, izigubhu, amathangi, amathangi kaphethiloli, izithiyo - ngokuncibilikisa inhlaka, iyenze ibe isimo esithambile, bese uyifutha ngomoya ngaphakathi kwesikhunta. Lona umhlahlandlela womkhiqizi: indlela umshini osebenza ngayo, izinhlobo ozoziqhathanisa, izingxenye ezinquma ngempela ikhwalithi, okukhiphayo kanye nezibalo zezindleko, nokuthi ungakhetha kanjani okulungile. Isebenzisa iminyaka engu-20+ yokwakha le mishini, ngakho ukuhweba lapha yikhona okunquma izindleko nekhwalithi kulayini wangempela.

Umshini wokubumba we-jerry ungavuthela (futhi umshini wokubumba i-spelled blow) usebenzisa i-extrusion blow molding ukwakha amathini angenalutho e-HDPE ne-PP - amathini kawoyela, iziqukathi zamakhemikhali, izithwali zamanzi namathini aqoqwayo - kusukela cishe ku-1 L kuya ku-30 ​​L. Lo mhlahlandlela uhlanganisa ukucushwa komshini, indlela yokubala okukhiphayo kwangempela, izindleko zokusebenza, izinto zokwakha, ukusetha okuzenzakalelayo kanye nendlela yokukhetha ukusetha okulungile.

Umshini wokubumba ipulasitiki ukhiqiza imikhiqizo yepulasitiki engenalutho ngokufudumeza i-resin, iyenze ibe ishubhu elithambile noma i-preform, ifake umoya ocindezelwe ngaphakathi kwesikhunta, bese uyipholisa engxenyeni eqediwe - amabhodlela, ama-jerry can, izigubhu neziqukathi zezimboni. Izinhlobo eziyinhloko i-extrusion, umjovo kanye ne-injection stretch blow blow molding.
