Iintlobo zeemveliso ezinokuveliswa ngumatshini wokubumba ovuthelayo

Oomatshini bokubumba bavuthela baguqula ukuveliswa kwezinto zemihla ngemihla. Udibana nendalo yabo yonke imihla, ukusuka kwiibhotile zeplastiki kunye nezikhongozeli ukuya kwiindawo zeemoto kunye nezinto zokudlala. Aba matshini bagqwesa ekwenzeni iimveliso ezinemilo eyahlukeneyo kunye nobukhulu. Ukuguquguquka kwabo kuvumela ukwenza izinto ezinjengeejagi zobisi, iibhotile zeshampu, kunye nezixhobo zebala lokudlala. Imarike yokubumba ifuthe lehlabathi, ixabisaI-78 yeebhiliyoni zeerandingo 2019, iyaqhubeka ikhula, ibalaselisa imfuno yaba matshini eziguquguqukayo. Ngezinto ezifana ne-polyethylene, i-polypropylene, kunye ne-polyethylene terephthalate, oomatshini bokubumba abavuthela bavelisa iimveliso ezizinzileyo kunye nezikhaphukhaphu ezihlangabezana neemfuno ezahlukeneyo.

Iintlobo zeeNkqubo zokuBumba iBlow

Oomatshini bokubumba bavuthela banika iinkqubo ezahlukeneyo zokwenza uluhlu olubanzi lweemveliso. Inkqubo nganye ineempawu ezizodwa kunye nokusetyenziswa, okwenza ukuba zilungele iintlobo ezahlukeneyo zeemveliso.

Extrusion Vuthela Ukubumba

Ukubumba i-Extrusion blow yindlela eyaziwayo yokuvelisa izinto zeplastiki ezingenanto. Le nkqubo ibandakanya ukunyibilika kweplastiki ize iyenze ibe ngumbhobho, owaziwa ngokuba yicawa. I-parison ivuthelwa ngaphakathi komngundo ukuze ithathe ubume obufunekayo.

Imizekelo yeeMveliso

Unokufumana i-extrusion blow molding esetyenziselwa ukudala izinto zemihla ngemihla. Iimveliso eziqhelekileyo ziquka iibhotile zeplastiki, iingqayi, kunye nezikhongozeli. Le ndlela ikwavelisa iimilo ezinzima ngakumbi njengeebhotile zeoyile yemoto kunye nezixhobo zebala lokudlala.

Inkqubo Overview

Kwi-extrusion blow blowing, umatshini ukhupha ityhubhu yeplastiki etyhidiweyo. Umngundo uyawuvala umbhobho, uze umoya uwuvuthele ukuze uvumelane nokumila kwawo. Xa sele ipholile, ukungunda kuyavuleka, kwaye imveliso egqityiweyo iyakhutshwa. Le nkqubo ivumela ukuveliswa kwezinto ezinobukhulu obahlukeneyo kunye noyilo oluntsonkothileyo.

Isitofu Ukubumba Ukuvuthela

I-injection blow blowing idibanisa izinto zokubumba inaliti kunye nokubunjwa kokuvuthela. Ilungele ukuvelisa izikhongozeli ezincinci, ezichanekileyo ezinomphezulu ogqwesileyo.

Imizekelo yeeMveliso

Le nkqubo isoloko isetyenziselwa ukwenza iibhotile ezincinci, ezifana nezo zamayeza kunye nezithambiso. Unokuyibona kwakhona kwimveliso yeengqayi kunye nezinye izitya ezincinci.

Inkqubo Overview

Inkqubo iqala ngokutofa iplastiki etyhidiweyo kwimold preform. I-preform igqithiselwa kwi-blow mold, apho ifakwe khona ukuze yenze imveliso yokugqibela. I-injection blow blowing iqinisekisa ukuchaneka okuphezulu kunye nokungaguquguquki, iyenza ilungele iimveliso ezifuna ukunyamezelana okuqinileyo.

UkuBumba iBlow yolula

Ukubumba i-Stretch blow yinkqubo enamanyathelo amabini eyenza iimveliso eziqinileyo nezikhaphukhaphu. Isebenza ngokukodwa ekuveliseni iibhotile ezicacileyo kunye namandla.

Imizekelo yeeMveliso

Uya kufumana i-stretch blow molding esetyenziselwa ukwenza iibhotile ze-PET, ezifana nezo zamanzi kunye neziselo ezibandayo. Le nkqubo ikwasetyenziselwa ukuvelisa izikhongozeli ezifuna ukumelana nempembelelo ephezulu.

Inkqubo Overview

Inkqubo iqala ngokudala i-preform usebenzisa isitofu sokubumba. I-preform iphinda ifudunyezwe kwaye yolulwe zombini i-axially kunye ne-radially kwi-mold yokuvuthela. Oku kolula kulungelelanisa amakhonkco e-polymer, ukwandisa amandla kunye nokucaca kwemveliso yokugqibela. Ukubumba isivuthelo esolula kuyathandwa ngenxa yokukwazi ukuvelisa izikhongozeli ezomeleleyo nezibukekayo.

Izinto ezisetyenziswa kwiBlow Molding

Oomatshini bokubumba baxhomekeke kwizinto ezahlukeneyo ukuvelisa iimveliso ezihlala ixesha elide kunye neziguquguqukayo. Ukuqonda ezi mathiriyeli kukunceda ukhethe eyona ifanelekileyo kwiimfuno zakho ezithile.

Izinto eziqhelekileyo

Polyethylene (PE)

I-Polyethylene yinto esetyenziswa ngokubanzi ekubumbeni ukuvuthela. Uhlala uyibona kwiimveliso ezifana neejagi zobisi kunye neebhotile zokucoca. Ukuguquguquka kwayo kunye nokuqina kwayo kuyenza ilungele ukwenza izikhongozeli ezifuna ukumelana neempembelelo.

Iipolypropylene (PP)

I-Polypropylene inika ukuchasana kweekhemikhali okugqwesileyo. Uyifumana kwiimveliso ezifana neendawo zemoto kunye nezikhongozeli zokutya. Ukukwazi kwayo ukugcina imilo phantsi koxinzelelo kwenza kube yinto ekhethwayo kwizinto ezifuna ingqibelelo yesakhiwo.

Polyethylene Terephthalate (PET)

I-PET yaziwa ngokucaca kunye nokomelela kwayo. Udibana nayo kwiibhotile zesiselo kunye nokupakishwa kokutya. Ubume bayo obukhaphukhaphu kunye nokusebenziseka kwakhona kwenza ukuba ibe lukhetho lokusingqongileyo kwizicelo ezininzi.
