Intshayelelo: Xa sithatha ibhotile ye-shampoo eqhelekileyo, kuya kuba ne-PET logo phantsi kwebhotile, oku kuthetha ukuba le mveliso yibhotile ye-PET. Iibhotile ze-PET zisetyenziswa kakhulu kwishishini lokuvasa kunye nokukhathalela kwaye ubukhulu becala bunomthamo omkhulu. Kweli nqaku, sazisa ikakhulu ibhotile ye-PET njengesitya seplastiki.
Iibhotile ze-PET zizikhongozeli zeplastiki ezenziwe ngePETizinto zeplastikingenyathelo elinye okanye amanyathelo amabini. Iplastiki ye-PET ineempawu zobunzima bokukhanya, ukukhanya okuphezulu, ukuchasana kwempembelelo kwaye akukho lula ukuphuka.
Inkqubo yokuvelisa
1. Qonda i-preform
I-preform yimveliso eyenziwe ngenaliti. Njengomgangatho ophakathi ogqityiweyo wemveliso yokubumba i-biaxial stretch blow blown, i-bottleneck ye-preform igqityiwe ngexesha lenqanaba lokubumba, kwaye ubungakanani bayo abuyi kutshintsha ngexesha lokufudumala kunye nokwelula / ukuvuthela. Ubungakanani, ubunzima, kunye nobukhulu bodonga lwe-preform zizinto ekufuneka sizithathele ingqalelo xa sivuthela iibhotile.

B. Ukubumba ibhotile ye-embryo
2. Ukubumba ibhotile ye-PET
Indlela yenyathelo elinye
Inkqubo yokugqiba inaliti, ukunweba kunye nokuvuthela kumatshini omnye kuthiwa yinyathelo elinye. Indlela yenyathelo elinye kukwenza ukolula nokuvuthela emva kokuba i-preform ipholile emva kokubumba inaliti. Iinzuzo zayo eziphambili kukugcina amandla, imveliso ephezulu, akukho msebenzi wezandla kunye nokunciphisa ukungcola.
Indlela enamanyathelo amabini
Indlela enamanyathelo amabini yohlula inaliti kunye nokuzolula nokuvuthela, kwaye izenze koomatshini ababini ngamaxesha ahlukeneyo, okwakwaziwa ngokuba yinkqubo yokuzolula inaliti kunye nokuvuthela. Inyathelo lokuqala kukusebenzisa umatshini wokubumba inaliti ukutofa i-preform. Isinyathelo sesibini kukubuyisela i-preform yeqondo lokushisa kunye nokwelula kwaye uvuthele kwibhotile. Inzuzo yendlela yamanyathelo amabini kukuthenga i-preform yokubumba ukuvuthela. Inokunciphisa utyalo-mali (italente kunye nezixhobo). Umthamo we-preform uncinci kakhulu kunebhotile, ekulungele ukuthutha kunye nokugcinwa. I-preform eveliswe kwi-off-season inokuvuthelwa kwibhotile kwixesha eliphakamileyo.
3. Inkqubo yokubumba ibhotile ye-PET
1. PET imathiriyeli:
I-PET, i-polyethylene terephthalate, ebizwa ngokuba yi-polyester. Igama lesiNgesi yi-Polyethylene Terephthalate, eveliswa yi-polymerization reaction (i-condensation) yezinto ezimbini zemichiza ekrwada: i-terephthalic acid PTA (i-terephthalic acid) kunye ne-ethylene glycol EG (ethylicglycol).
2. Ulwazi oluqhelekileyo malunga nomlomo webhotile
Umlomo webhotile uneediameters ze Ф18, Ф20, Ф22, Ф24, Ф28, Ф33 (ehambelana nobukhulu be-T bomlomo webhotile), kwaye inkcazo yentambo idla ngokwahlulwa ibe: 400, 410, 415 (ehambelana nenani ujika umsonto). Ngokuqhelekileyo, i-400 ngu-1 umsonto ojikayo, u-410 ngu-1.5 ojika umsonto, kwaye u-415 ngu-2 ojika umsonto ophezulu.
3. Umzimba webhotile
Iibhotile ze-PP kunye ne-PE ubukhulu becala ziyimibala eyomeleleyo, i-PETG, i-PET, i-PVC ibonakala ngokucacileyo, okanye inemibala kunye ne-transparent, kunye nemvakalelo yokuguquguquka, kunye nemibala eqinile ayifane isetyenziswe. Iibhotile ze-PET nazo zinokutshizwa. Kukho indawo yeconvex emazantsi ebhotile ebunjiweyo. Kukhanya ngakumbi phantsi kokukhanya. Kukho umgca wokubopha emazantsi ebhotile efakwe ibhotile.
4. Ukuthelekisa
Iimveliso eziphambili ezihambelanayo kwiibhotile ezivuthelayo ziiplagi zangaphakathi (eziqhelekileyo zisetyenziselwa izinto zePP kunye ne-PE), ii-caps zangaphandle (eziqhelekileyo zisetyenziselwa i-PP, i-ABS kunye ne-acrylic, i-electroplated, kunye ne-electroplated aluminiyam, esetyenziselwa kakhulu ukutshiza i-toner), i-pump ikhava yentloko. (esidla ngokusetyenziswa kwi-essence kunye nelotion), iikepusi ezidadayo, ii-flip caps (ii-flip caps neecaps ezidadayo zisetyenziswa ubukhulu becala kwimigca emikhulu yekhemikhali yemihla ngemihla), njl.njl.
Isicelo
Iibhotile ze-PET zisetyenziswa kakhulu kwishishini lezithambiso,
ubukhulu becala kwishishini lokuvasa nokukhathalela,
kubandakanya ishampoo, iibhotile zejeli yeshawari, itoner, iibhotile zokususa izimonyo, njl.
zonke zivuthelwe.
Iingqwalasela zokuthenga
1. I-PET yenye kuphela yezinto ezikhoyo kwiibhotile zokuvuthela. Kukwakho neebhotile ze-PE (ezithambileyo, ezinemibala eyomeleleyo, ukwakheka kwexesha elinye), iibhotile zokuvuthela zePP (ziqina, imibala eyomeleleyo, ibunjwa okwexesha elinye), iibhotile zokuvuthela ze-PETG (ukukhanya okungcono kune-PET, kodwa hayi ngokuqhelekileyo. isetyenziswe e-China, ixabiso eliphezulu, inkunkuma ephezulu, i-time-time forming, i-non-recyclable-bottles, iibhotile ze-PVC (ezinzima, azikho indalo, zingaphantsi kwe-PET, kodwa zikhanya ngakumbi kune-PP kunye ne-PE)
2. Isixhobo esinenyathelo elinye siyabiza, izixhobo ezinamanyathelo amabini azibizi kakhulu
3. Iimbumba zeebhotile ze-PET zinexabiso eliphantsi.
