Tikatenga botolo la shampoo lomwe limagwiritsidwa ntchito kwambiri, padzakhala chizindikiro cha PET pansi pa botolo, zomwe zikutanthauza kuti mankhwalawa ndi botolo la PET. Mabotolo a PET amagwiritsidwa ntchito kwambiri pochapa ndi kusamalira, makamaka pamlingo waukulu.
一、Tanthauzo la Katundu
Mabotolo a PET amapangidwaPET pulasitikindipo amakonzedwa kudzera munjira imodzi kapena ziwiri kuti apeze zotengera zapulasitiki.
Pulasitiki ya PET ili ndi mawonekedwe a kulemera kopepuka, kuwonekera kwambiri, kukana kwamphamvu komanso kosavuta kuthyoka.
二、 Njira yopanga
1. Kumvetsetsa preform
Preform ndi mankhwala opangidwa ndi jekeseni. Monga chinthu chapakatikati chomaliza chopangira biaxial chowongoka chowongoleredwa, botolo la preform lamalizidwa panthawi yopangira jakisoni, ndipo kukula kwake sikungasinthe pakuwotcha ndi kutambasula / kuwomba. Kukula, kulemera, ndi makulidwe a khoma la preform ndi zinthu zomwe tiyenera kuziganizira kwambiri tikamawombera mabotolo.
Mapangidwe a preform
Preform akamaumba
2. Kupanga botolo la PET
Njira imodzi
Njira yomaliza jekeseni, kutambasula ndi kuwomba mu makina amodzi imatchedwa njira imodzi. Njira imodzi ndikuchita kutambasula ndi kuwomba pambuyo pozizira preform pambuyo poumba jekeseni. Ubwino wake waukulu ndikupulumutsa mphamvu, zokolola zambiri, palibe ntchito yamanja komanso kuchepetsedwa kwa kuipitsa.
Njira ziwiri
Njira ziwirizi zimalekanitsa jekeseni ndikuwomba kuwombera ndikuzipanga pamakina awiri nthawi zosiyanasiyana. Imatchedwanso jekeseni kutambasula kuwomba ndondomeko akamaumba. Chinthu choyamba ndikugwiritsa ntchito makina opangira jekeseni kuti mulowetse preform. Gawo lachiwiri ndikutenthetsanso preform kutentha kwachipinda ndikutambasulira mu botolo. Ubwino wa njira ziwirizi ndikuti preform ikhoza kugulidwa kuti ipangitse kuwomba. Itha kuchepetsa ndalama (talente ndi zida). Voliyumu ya preform ndi yaying'ono kwambiri kuposa ya botolo, yomwe ndi yabwino mayendedwe ndi kusungidwa. Preform yomwe imapangidwa mu nyengo yopuma imatha kuwomberedwa mu botolo munyengo yam'mwamba.
3. PET botolo akamaumba ndondomeko
三、Zinthu ndi kapangidwe
1. PET zinthu
PET, polyethylene terephthalate, yotchedwa polyester. Dzina lachingerezi ndi Polyethylene Terephthalate, lomwe limapangidwa ndi polymerization reaction (condensation) ya zida ziwiri zamankhwala, terephthalic acid PTA (terephthalic acid) ndi ethylene glycol EG (ethylicglycol).
2. Chidziwitso chodziwika bwino pakamwa pa botolo
Pakamwa pa botolo ili ndi ma diameter a Ф18, Ф20, Ф22, Ф24, Ф28, Ф33 (mogwirizana ndi kukula kwa T kwa pakamwa pa botolo), ndipo maulusi amatha kugawidwa mu: 400, 410, 415 (mogwirizana ndi chiwerengero cha ulusi wozungulira). Nthawi zambiri, 400 ndi 1 ulusi wokhota, 410 ndi 1.5 ulusi wokhota, ndipo 415 ndi 2 ulusi wokhota kwambiri.
3. Thupi la botolo
Mabotolo a PP ndi PE nthawi zambiri amakhala amitundu yolimba, PETG, PET, zida za PVC nthawi zambiri zimakhala zowonekera, kapena zowoneka bwino, zowoneka bwino, ndipo mitundu yolimba siyigwiritsidwa ntchito kawirikawiri. Mabotolo a PET amathanso kupopera. Pali kadontho kowoneka pansi pa botolo lowumbidwa ndi kuwomba. Kuwala kwambiri pansi pa kuwala. Pali mzere womangira pansi pa botolo lobayidwa ndi nkhonya.
4. Zothandizira zothandizira
Zida zazikulu zothandizira mabotolo owombera ndi mapulagi amkati (omwe amagwiritsidwa ntchito kwambiri pazida za PP ndi PE), zipewa zakunja (zomwe zimagwiritsidwa ntchito kwambiri pa PP, ABS ndi acrylic, komanso electroplated, ndi aluminiyamu ya electroplated, yomwe imagwiritsidwa ntchito kwambiri popopera toner), mutu wapampu wakunja. zophimba (zomwe zimagwiritsidwa ntchito nthawi zambiri ngati mafuta odzola), zipewa zoyandama, zotchingira (zophimba ndi zipewa zoyandama zimagwiritsidwa ntchito kwambiri popanga mizere yayikulu yamankhwala tsiku lililonse), ndi zina.
四、Mapulogalamu amakampani
Mabotolo a PET amagwiritsidwa ntchito kwambiri pamakampani opanga zodzoladzola, makamaka m'makampani otsuka, kuphatikiza shampu, mabotolo a gel osamba, toner, mabotolo ochotsa zodzoladzola, ndi zina zotere, zomwe zimawombedwa ndikupangidwa.
五, Zolinga zogula
1. Mabotolo owombera amatha kupangidwa ndi zipangizo, PET ndi imodzi mwa izo, palinso mabotolo otsekemera a PE (ofewa, mitundu yolimba kwambiri, kupanga nthawi imodzi), mabotolo owombera PP (olimba, mitundu yolimba kwambiri, kupanga nthawi imodzi. ), PETG kuwomba mabotolo (mawonekedwe bwino kuposa PET, koma osati ambiri ntchito ku China, kukwera mtengo, zinyalala mkulu, nthawi imodzi kupanga, zinthu sanali recyclable), mabotolo PVC kuwomba (zolimba, osati zachilengedwe, zochepa mandala kuposa PET, koma kuwala bwino kuposa PP ndi PE)
2. Zida za sitepe imodzi ndizokwera mtengo, magawo awiri ndi otsika mtengo
3. PET botolonkhungu ndi zotchipa.
4. Mavuto odziwika bwino ndi mayankho, onani kanema
