Inkqubo yokubumba izinto zokupakisha zeplastiki kwishishini lezinto zokuthambisa yahlulwe kakhulu ibe ziindidi ezimbini: ukubumba ngenaliti kunye nokubumba ngebhombu.
Ukubumba ngenaliti
Iyintoni inkqubo yokubumba ngenaliti?
Ukubumba ngenaliti yinkqubo yokufudumeza nokwenza iplastiki ibe yiplastiki (ukufudumeza nokunyibilikisa ibe lulwelo, iplastiki), uze ufake uxinzelelo ukuze uyifake kwindawo evaliweyo yesikhunta, uyivumele ukuba iphole kwaye iqine kwisikhunta, ukuze kuveliswe imveliso enobume obufanayo nesikhunta. Ifanelekile ukuvelisa ngobuninzi iindawo ezineemilo ezintsonkothileyo.
Iimpawu zenkqubo yokubumba ngenaliti:
1. Isantya semveliso esikhawulezayo, ukusebenza kakuhle, inqanaba eliphezulu lokusebenza ngokuzenzekelayo
2. Imveliso inobunono obuphezulu, kwaye impazamo yokubonakala incinci kakhulu
3. Uyakwazi ukuvelisa iindawo ezineemilo ezintsonkothileyo
4. Ixabiso eliphezulu lokubumba
Uninzi lwethuibhotile engenamoya, ibhotile yeloshini enodonga oluphindwe kabiniziveliswa ngenkqubo yokujova.
Ukubumba ngesandi
Iimpawu zenkqubo yokubumba ngesibetho:
Ukuthatha izifundo kwinkqubo yendabuko yokuvuthela iglasi, ukubumba ngebhombu kusebenzisa umoya ocinezelweyo onoxinzelelo oluthile ukuze kuvuthe kwaye kupholise i-preform (umzimba weplastiki oneetyhubhu ezigqityiweyo) kwi-mold ibe yinkqubo yokubumba iimveliso ezingenanto. Ifanelekile kwimveliso enkulu yezikhongozeli zeplastiki ezingenazinto.
Zithini iimpawu zenkqubo yokubumba nge-blow?
1. Indlela elula yokuvelisa, ukusebenza kakuhle kwemveliso kunye nokwenza izinto ngokuzenzekelayo
2. Ukuchaneka okuphantsi kobukhulu
3. Kukho imiqathango ethile kwimilo yemveliso
4. Ixabiso eliphantsi lokubumba
Ngokweendlela ezahlukeneyo zokuvelisa kunye neenkqubo, ukubumba ngombhobho kunokwahlulwahlulwa kube ziintlobo ezintathu: ukuvuthela ngombhobho, ukuvuthela ngombhobho, kunye nokuvuthela ngombhobho ngombhobho.
Eyokuqala kukucinezela nokuvuthela. Njengoko igama lisitsho, ukuvuthela okuphumayo kunamanyathelo amabini amakhulu: ukuvuthela kunye nokubumba okuphumayo.
Inyathelo lokuqala kukukhupha ukuvalwa kwe-parison-mold.Isixhobo sokukhupha siyaqhubeka nokuxinana ukuze senze i-parison engenanto.Xa i-parison ikhutshiwe ukuya kubude obumiselweyo, umphezulu we-parison uyanqunyulwa ukuya kubude obufanelekileyo kwinxalenye enye, kwaye ii-molds ezikumacala asekhohlo nasekunene ziyavalwa.
Inyathelo lesibini, ukufakelwa komoya - ukucheba.Umoya ocinezelweyo ufakwa kwi-preform nge-mandrel ukuze uvuthe.I-parison inamathela ngokusondeleyo eludongeni lwangaphakathi lwe-mold ukuze iphole kwaye imile, kwaye imveliso isuswa kwi-mold, kwaye kwenziwa ukusika okwesibini.Ixabiso lezixhobo zokukhupha nokukhupha umoya kunye neenkuni liphantsi kakhulu, kwaye neendleko zemveliso nazo ziphantsi kakhulu.
Nangona kunjalo, ukukhazimla kwenzeka ngexesha lenkqubo yokuvelisa, kwaye umlomo kunye nomzantsi webhotile kufuneka zichetywe ngoomatshini okanye ngesandla, kwaye ngamanye amaxesha umlomo webhotile kufuneka ucocwe kwaye uchetywe.
Iibhotile zeplastiki ezibunjiweyo ezenziwe nge-extrusion-blow zinomgca wokuhlukana (i-linear protrusion) ezantsi, kwaye umlomo webhotile urhabaxa kwaye awugudi, ngoko ke ezinye zinomngcipheko wokuvuza kolwelo. Ezi bhotile zihlala zenziwe ngezinto ze-PE kwaye zisetyenziswa kwizinto zokuthambisa ezifana neebhotile ze-foam, ii-lotions zomzimba, ii-shampoo kunye nee-conditioner.
Uhlobo lwesibini kukuvuthela ngenaliti, olunezinyathelo ezimbini ezibalulekileyo: ukubumba ngenaliti.
Inyathelo 1: Lungisa ukuvalwa kwe-injection-mold.
Sebenzisa inkqubo yokubumba ngenaliti ukuvelisa i-parison esezantsi, kwaye ikhonsoli ijikeleza nge-120° ukuya kwikhonkco lokubumba nge-blow.
Isikhunta siyavalwa, kwaye umoya ocinezelweyo ungeniswa kwi-parison nge-mandrel pores ukuze kufakwe isikhunta.
Inyathelo lesi-2: Lungisa ukupholisa nokunciphisa ukuhla kwamandla emali.
Emva kokuba imveliso ebunjiweyo inyangiwe ngokupheleleyo kwaye ibunjiwe, ikhonsoli ijikeleza i-120° ukuze ihambise imveliso. Akukho mfuneko yokunciphisa okwesibini, ngoko ke umgangatho wokwenza izinto ngokuzenzekelayo kunye nokusebenza kakuhle kwemveliso kuphezulu. Ngenxa yokuba ibhotile ivuthelwe kwi-parison ebunjiweyo ngenaliti, umlomo webhotile uthe tyaba kwaye ibhotile ineempawu zokutywina ezingcono, ezifana ne-Uthotho lweebhotile ezivuthuzayo zeTB07.
Uhlobo lwesithathu kukutsala amanqaku nokuvuthela. Lwahlulwe lwaba ngamanyathelo amathathu: ukubumba i-injection-stretching-blow molding.
Ngokungafaniyo nohlobo lokuvuthela ngenaliti olujikajikayo, ukuvuthela ngenaliti yindlela yokuvelisa umgca wokuhlanganisa.
Inyathelo 1: Lungisa ukuvalwa kwe-injection-mold
Faka i-preform eyenziwe ngenaliti kwi-blow mold
Faka intonga yokwelula uze uvale isikhunta ngasekhohlo nasekunene
Inyathelo lesi-2: Ukuzolula-Ukuvuthela-Ukuphola kunye nokususa i-oulding
Intonga yokulula yoluliwe ngobude, ngelixa umoya ufakwa ngentonga yokulula ukuze yolulwe ecaleni.
Ukupholisa nokubumba, ukususa nokukhupha imveliso
Ukufutha ngomjovo yeyona ndlela iphezulu yomgangatho, ukuchaneka kunye nexabiso eliphantsi kwinkqubo yokubumba ngomjovo.
Okwangoku, kukho iindlela ezimbini zemveliso kwinkqubo yokuvuthela ukolula inaliti, ezibizwa ngokuba: indlela yenyathelo elinye kunye nendlela yenyathelo ezimbini. Ukubumba ngenaliti kunye nokubumba ngebhombu kugqitywa kunye ngendlela yenyathelo elinye, kwaye amanyathelo amabini agqitywa ngokuzimeleyo njengendlela yenyathelo ezimbini.
Xa kuthelekiswa nendlela enamanyathelo amabini, indlela enenyathelo elinye igqitywa kwizixhobo ezinenyathelo elinye ukusuka kwizinto eziluhlaza ukuya kwimveliso egqityiweyo. Inkqubo yemveliso ilula kwaye akukho kufudumeza okwesibini okuvunyelweyo, ngoko ke ukusetyenziswa kwamandla kuphantsi.
Le ndlela inamanyathelo amabini ifuna ukujova kwangaphambili, ize emva koko isetyenzwe okwesibini kumatshini wokubumba ngokuvuthela. Ukubumba ngokuvuthela kufuna ukufudunyezwa kwesibini kwe-preform epholileyo, ngoko ke ukusetyenziswa kwamandla kuphezulu.
