Intshayelelo: Xa sithatha ibhotile yeshampu eqhelekileyo, kuya kubakho uphawu lwePET ezantsi kwebhotile, oko kuthetha ukuba le mveliso yibhotile yePET. Iibhotile zePET zisetyenziswa kakhulu kushishino lokuhlamba nokunyamekela kwaye zinomthamo omkhulu. Kweli nqaku, sizazisa kakhulu ibhotile yePET njengesitya seplastiki.
Iibhotile zePET zizikhongozeli zeplastiki ezenziwe ngePETizinto zeplastikingokusebenzisa inyathelo elinye okanye amanyathelo amabini. Iplastiki yePET ineempawu zobunzima obulula, ukukhanya okuphezulu, ukumelana neempembelelo kwaye kulula ukuphula.
Inkqubo yokuvelisa
1. Qonda i-preform
I-preform yimveliso ebunjiweyo ngenaliti. Njengemveliso ephakathi egqityiweyo yokubumba i-biaxial stretch blowing elandelayo, i-bottleneck ye-preform igqityiwe ngexesha lesigaba sokubumba inaliti, kwaye ubungakanani bayo abuyi kutshintsha ngexesha lokufudumeza kunye nokusolula/ukuvuthela. Ubungakanani, ubunzima, kunye nobukhulu bodonga lwe-preform zizinto ekufuneka siziqwalasele xa sivuthela iibhotile.
A. Ulwakhiwo lwe-embryo yebhotile
B. Ukubumba umbungu webhotile
2. Ukubumba iibhotile zePET
Indlela yenyathelo elinye
Inkqubo yokujova, ukolula kunye nokuvuthela kumatshini omnye ibizwa ngokuba yindlela yenyathelo elinye. Indlela yenyathelo elinye kukwenza ukolula kunye nokuvuthela emva kokuba i-preform ipholile emva kokubumba ngenaliti. Iingenelo zayo eziphambili kukonga umbane, ukusebenza okuphezulu, ukungasebenzi ngezandla kunye nokunciphisa ungcoliseko.
Indlela enamanyathelo amabini
Indlela enamanyathelo amabini yahlula ukujova kunye nokolula kunye nokuvuthela, kwaye iyenza kumatshini amabini ngamaxesha ahlukeneyo, okwaziwa ngokuba yinkqubo yokolula kunye nokuvuthela ngenaliti. Inyathelo lokuqala kukusebenzisa umatshini wokubumba ngenaliti ukufaka i-preform. Inyathelo lesibini kukuphinda ufudumale i-preform yobushushu begumbi uze uyolule kwaye uyivuthele kwibhotile. Inzuzo yendlela enamanyathelo amabini kukuthenga i-preform yokubumba ngentambo. Inokunciphisa utyalo-mali (italente kunye nezixhobo). Umthamo we-preform umncinci kakhulu kunowebhotile, olungele ukuthuthwa kunye nokugcinwa. I-preform eveliswa ngexesha lokungabikho kwexesha inokuvuthela kwibhotile ngexesha lonyaka eliphezulu.
3. Inkqubo yokubumba iibhotile zePET
1. Izinto zePET:
I-PET, i-polyethylene terephthalate, ebizwa ngokuba yi-polyester. Igama lesiNgesi yiPolyethylene Terephthalate, eveliswa yi-polymerization reaction (condensation) yezinto ezimbini zekhemikhali: i-terephthalic acid i-PTA (terephthalic acid) kunye ne-ethylene glycol EG (ethylicglycol).
2. Ulwazi oluqhelekileyo malunga nomlomo webhotile
Umlomo webhotile uneedayamitha ze-Ф18, Ф20, Ф22, Ф24, Ф28, Ф33 (ezihambelana nobukhulu be-T bomlomo webhotile), kwaye iinkcukacha zomsonto zihlala zahlulwe zibe: 400, 410, 415 (ezihambelana nenani lokujika komsonto). Ngokubanzi, i-400 yijika lomsonto eli-1, i-410 yijika lomsonto eli-1.5, kwaye i-415 yijika lomsonto eli-2 eliphezulu.
3. Umzimba webhotile
Iibhotile zePP kunye nePE ikakhulu zinemibala eqinileyo, iPETG, iPET, iPVC ikakhulu zibonakala ngokucacileyo, okanye zinemibala kwaye ziyabonakala, zinombono wokukhanya, kwaye imibala eqinileyo ayisetyenziswa rhoqo. Iibhotile zePET nazo zinokutshizwa. Kukho indawo engqukuva ezantsi kwebhotile ebunjiweyo. Ikhanya ngakumbi xa kukhanya. Kukho umgca wokubopha ezantsi kwebhotile efakwe umoya.
4. Ukuthelekisa
Iimveliso eziphambili ezihambelana neebhotile zokuvuthela ziiplagi zangaphakathi (ezisetyenziswa kakhulu kwizixhobo zePP kunye nePE), iicap zangaphandle (ezisetyenziswa kakhulu kwiPP, ABS kunye ne-acrylic, ezikwasetyenziswa ngombane, kunye ne-aluminium efakwe ngombane, ezisetyenziswa kakhulu kwi-spray toner), isiciko sentloko yepompo (esetyenziswa kakhulu kwi-essence kunye ne-lotion), iicap ezidadayo, ii-flip caps (ii-flip caps kunye neecap ezidadayo zisetyenziswa kakhulu kwimigca yamakhemikhali yemihla ngemihla ehamba kakhulu), njl.
Isicelo
Iibhotile zePET zisetyenziswa kakhulu kwishishini lezinto zokuthambisa,
ikakhulu kwishishini lokuhlamba nokunyamekela,
kuquka ishampu, iibhotile zejeli zeshawa, itoner, iibhotile zokususa izimonyo, njl.
zonke zivuthukile.
Izinto ekufuneka ziqwalaselwe xa uthenga
1. I-PET yenye yezinto ezifumanekayo kwiibhotile zokuvuthela. Kukwakho neebhotile zokuvuthela ze-PE (ezithambileyo, ezinemibala eqinileyo, ezibumba kube kanye), iibhotile zokuvuthela ze-PP (eziqinileyo, ezimibala eqinileyo, ezibumba kube kanye), iibhotile zokuvuthela ze-PETG (ezicacileyo ngakumbi kune-PET, kodwa azisetyenziswa rhoqo eTshayina, zibiza kakhulu, zichitha imali eninzi, zibumba kube kanye, izinto ezingaphinde zisetyenziswe), iibhotile zokuvuthela ze-PVC (eziqinileyo, ezingangcolisiyo okusingqongileyo, ezingacacanga kangako kune-PET, kodwa zikhanya ngakumbi kune-PP kunye ne-PE)
2. Izixhobo ezinenyathelo elinye zibiza kakhulu, izixhobo ezinenyathelo ezimbini zibiza kancinci
3. Ii-PET bottle molds zibiza kancinci.
