Impendulo esheshayo
Vuthela ukubumbainfutha ishubhu lepulasitiki elincibilikisiwe ngokumelene nesikhunta ngemizuzwana ukuya emaminithini. Kubiza kakhulu ekusebenzeni kwamathuluzi futhi iwina ngevolumu.Ukubumba okujikelezayoiwisa impushana yepulasitiki ngaphakathi kwesikhunta esishisayo, esiphenduka kancane. Imijikelezo yayo igijima amashumi emizuzu, kodwa ithuluzi lishibhile futhi izingxenye ziphuma zingenamthungo. Umthamo wonyaka uvamise ukunquma: amanani aphansi athanda isikhunta esishibhile se-rotomolding; imiqulu yokukhiqiza ivuna isivinini sokubumba. Emathangeni, ama-IBC, izinto ezintantayo, kanye nezithiyo, umshini wokubumba owu-250-litre uqhuba izingcezu ezingu-300 ngehora umjikelezo owomile, kuyilapho umjikelezo we-rotomolding wenza ingxenye eyodwa ngesikhathi esifanayo.
Zombili izinqubo zenza izingxenye zepulasitiki ezingenalutho. Okwamathangi, ama-kayak, okuntantayo, nezithiyo, noma yiliphi lingenza umsebenzi. Ngakho ukukhetha kubalulekile, futhi kubiza imali yangempela ukwenza iphutha.
Ama-athikili amaningi ngalesi sihloko avela ezitolo zokubumba ezithanda noma iyiphi inqubo ezithengiswayo. Sakha imishini yokubumba, ngakho-ke sizokusho lokho ngokusobala. Ukugcina lokhu kuwusizo, sengeze isigaba esigcwele sokuthi i-rotomolding iwina nini - ngoba kwesinye isikhathi iyaphumelela.
Nasi isiqhathaniso esiqotho umthengi akudingayo.
Izinqubo ezimbili, umzuzu owodwa ngamunye
Umshini wokubumba ukhipha ishubhu elingenalutho lepulasitiki elincibilikisiwe elibizwa ngokuthi i-parison. Isikhunta sivala ishubhu, umoya usivuthele ezindongeni, futhi ingxenye iyaphola bese iphuma. Umjikelezo ugijima ngemizuzwana ukuze uthole amabhodlela kanye nemizuzu embalwa izingxenye ezinkulu.
Umshini wokubumba ojikelezayo ulayisha impushana yepulasitiki esikhunjeni esingenalutho. Isikhunta sivula izimbazo ezimbili ngaphakathi kuhhavini, futhi impushana encibilikayo imboza ingaphakathi njengesikhumba esingenamthungo. Bese iphola isaphenduka, bese iphuma ingxenye.
Imikhiqizo efanayo, ephambene ne-physics. Umuntu usebenzisa ingcindezi nesivinini. Enye isebenzisa ukushisa, amandla adonsela phansi, nesikhathi.

Umehluko wangempela: ingcindezi nesikhathi
Ukudla okudlela endlini:i-blow molding ithenga isivinini ngengcindezi kanye ne-pricier tooling. I-Rotomolding ithenga amathuluzi ashibhile ngokuhamba kwesikhathi.
Yonke imigqa kulelo thebula ilandela iqiniso elilodwa. Ukubumba i-Blow kwakha ingxenye ngaphansi kwengcindezi, kumcimbi owodwa osheshayo. I-Rotomolding iwenza ngengcindezi ye-ambient, kancane, njengoba impushana incibilika odongeni.
Ingcindezi ichaza izindleko zamathuluzi. Izibungu ezivuthelayo kufanele zimelane namandla okubamba - 800 kuya ku-1800 kN emishinini yethu emikhulu - ngakho-ke zenziwa ngomshini ngensimbi yamathuluzi. I-Rotomolds ibhekana cishe namandla, ngakho-ke i-aluminium eshibhile iyasebenza.
Isikhathi yintengo ye-rotomolding ekhokhayo. Ukushisa isikhunta kuhhavini nokuyipholisa ngenkathi siphenduka kuthatha amashumi emizuzu. Alikho ikhono elifinyeza lokho.
I-volume breakeven: lapho isinqumo senziwa khona
Ukudla okudlela endlini:ngaphansi kwenani le-breakeven, ithuluzi elishibhile le-rotomolding liyawina. Ngaphezu kwalokho, isivinini somjikelezo wokubumba siyawina - futhi igebe liyakhula minyaka yonke okhiqizayo.
Lesi sibalo sixazulula izinqumo eziningi zangempela. I-Rotomolding iqala eshibhile, ngoba isikhunta sibiza ingxenyenamba yesikhunta sokushaywa. Kodwa zonke izingxenye ziphethe umjikelezo ohamba kancane.
Ukubumba i-Blow kuyapheqa lokho. Isikhunta sibiza ngaphezulu ngaphambili. Khona-ke umshini wenza izingxenye ngokushesha okukhulu, ihora ngalinye, ukuphila kohlelo.
Izinombolo zangempela zibonisa igebe. EyethuKGB120E-class umshiniIziqukathi ezingu-250-litre zisebenzisa izingcezu ezingu-300 ngehora umjikelezo owomile. Iseli le-rotomolding elenza ithangi elifanayo liqeda ingxenye eyodwa ngomjikelezo we-ovini nokupholile.
Ngakho umbuzo wangempela awukona ukuthi "yikuphi okushibhile?" Buza ukuthi "kushibhile ngenani lakho lonyaka?" Izingxenye ezingamakhulu ambalwa ngonyaka zivuna i-rotomolding. Izinkulungwane kuya emashumini ezinkulungwane zivuna ukulolongwa ngomkhawulo obanzi.
Indawo ye-crossover: amathangi, ama-kayak, ama-floats, izithiyo
Ukudla okudlela endlini:imikhiqizo abantu abayibiza ngokuthi "izingxenye ze-rotomolding" - amathangi, ama-kayak, izinto ezintantayo, izithiyo - zisebenza ngemishini emikhulu yokubumba i-accumulator ngevolumu.
Izindatshana eziningi zokuqhathanisa ziyeqa le ngxenye. Umndeni wonke wemikhiqizo emikhulu ulingana nezinqubo zombili.
Amathangi amanzi. 1000-litre IBC amabhodlela. Ama-kayak nezikebhe ezincane. Izintanta namabhuya. Izithiyo zomgwaqo. Konke okungenalutho, konke kukhulu, konke kuxhumene ne-rotomolding ngomkhuba - futhi konke kusebenza namuhla emishinini yokubumba.
Lena yimisebenzi yangempela evela ebangeni lethu. Imishini yethu ye-accumulator yenza amathangi amanzi futhiAmabhodlela e-IBC afinyelela ku-1000 amalitha, futhi uchungechunge lwe-KGS lwamasilinda amathathu lufinyelela kuziqukathi ezingu-2000-litre, kanye nezinto ezintantayo, izithiyo, nezingxenye zesigaba se-kayak ku-HDPE ne-HMWHDPE.
Kungani ushintsha lezi zingxenye zisuka ku-roto ziye kuphephetha njengoba ivolumu ikhula? Isikhathi somjikelezo. Lapho ithangi lithengisa emashumini ezinkulungwane ngonyaka, inqubo eyenza ingxenye eyodwa ngomjikelezo we-ovini ayikwazi ukuqhubeka. Ukwengeza izingalo ze-roto kusho ukwengeza ohhavini, indawo yaphansi, namandla ingxenye ngayinye.
Ukuhweba udonga. Ithangi eline-rotomold lisebenza ngaphandle komthungo futhi liwugqinsi ngokulinganayo. Igalelo elibunjiwe liphethe umugqa wokuncisha futhi lithembele kuwoukulawulwa kokuqina kodonga okuhleliweukubeka impahla lapho umthwalo uhlezi. Kwenziwe kahle, ingxenye ebunjwe ngokushaywa ihlangabezana nomsebenzi ofanayo ngesisindo esilula - okusho futhi inhlaka encane ngengxenye ngayinye.
