Xa sithatha ibhotile yeshampu esetyenziswa rhoqo, kuya kubakho uphawu lwePET ezantsi kwebhotile, oko kuthetha ukuba le mveliso yibhotile yePET. Iibhotile zePET zisetyenziswa kakhulu kwishishini lokuhlamba nokunyamekela, ikakhulu zinomthamo omkhulu.
一, Inkcazelo yeMveliso
Iibhotile ze-PET zenziwe ngeIplastiki yePETkwaye zicutshungulwa ngeenkqubo zenyathelo elinye okanye ezimbini ukuze kufunyanwe izikhongozeli zeplastiki.
Iplastiki yePET ineempawu zobunzima obulula, ukukhanya okuphezulu, ukumelana neempembelelo kwaye akulula ukuphula.
二、Inkqubo yokwenziwa
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.
Ulwakhiwo lwangaphambili
Ukubumba kwangaphambili

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
Le ndlela inamanyathelo amabini yahlula ukubumba ngenaliti kunye nokusonga kwaye iyenza kwiimashini ezimbini ngamaxesha ahlukeneyo. Ikwabizwa ngokuba yinkqubo yokubumba ngenaliti. Inyathelo lokuqala kukusebenzisa umatshini wokubumba ngenaliti ukufaka i-preform. Inyathelo lesibini kukuphinda ufudumale i-preform kubushushu begumbi kwaye uyivuthele kwibhotile. Inzuzo yendlela enamanyathelo amabini kukuba i-preform inokuthengwa ukuze ivuthele. Inokunciphisa utyalo-mali (italente kunye nezixhobo). Umthamo we-preform umncinci kakhulu kunowebhotile, okulungele ukuthuthwa kunye nokugcinwa. I-preform eveliswa ngexesha lokungabikho kwexesha ingavuthelwa kwibhotile ngexesha lonyaka eliphezulu.

Izinto kunye nesakhiwo
1. Izinto zePET
I-PET, i-polyethylene terephthalate, ebizwa ngokuba yi-polyester. Igama lesiNgesi yiPolyethylene Terephthalate, eveliswa yi-polymerization reaction (condensation) yezinto ezimbini zekhemikhali eluhlaza, i-terephthalic acid 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, izinto zePETG, PET, PVC zihlala zicacile, okanye zinombala ocacileyo, zinombono wokukhanya, kwaye imibala eqinileyo ayisetyenziswa rhoqo. Iibhotile zePET nazo zinokutshizwa. Kukho ichaphaza elijijekileyo ezantsi kwebhotile ebunjiweyo. Ikhanya ngakumbi xa kukhanya. Kukho umgca wokubopha ezantsi kwebhotile ebunjiweyo.
4. Izixhobo ezixhasayo
Izixhobo eziphambili zokuxhasa iibhotile 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 kwii-toner zokutshiza), ii-pump head zangaphandle (ezisetyenziswa kakhulu kwi-essences kunye ne-lotions), ii-floating caps, ii-flip caps (ii-flip caps kunye nee-floating caps zisetyenziswa kakhulu kwimigca yamakhemikhali yemihla ngemihla ehamba kakhulu), njl.
Izicelo zeShishini
Iibhotile zePET zisetyenziswa kakhulu kwishishini lezinto zokuthambisa, ikakhulu kwishishini lokucoca, kuquka ishampu, iibhotile zejeli yeshawa, itoner, iibhotile zokususa izimonyo, njl.njl., zonke ezivuthelwayo kwaye zenziwe.
五、Izinto ekufuneka uziqwalasele xa uthenga
1. Iibhotile zokuvuthela zingenziwa ngezinto, i-PET yenye yazo, 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 ngcono kune-PP kunye ne-PE)
2. Izixhobo zenyathelo elinye zibiza kakhulu, izixhobo zenyathelo ezimbini zibiza kancinci
3. Ibhotile yePETii-molds zibiza kancinci.
4. Iingxaki ezisemgangathweni eziqhelekileyo kunye nezisombululo, jonga ividiyo
