Chiyambi: Tikatenga botolo la shampoo wamba, padzakhala chizindikiro cha PET pansi pa botolo, zomwe zikutanthauza kuti mankhwalawa ndi botolo la PET. Mabotolo a PET amagwiritsidwa ntchito makamaka pamakampani ochapa ndi kusamalira ndipo amakhala ndi mphamvu zazikulu. M'nkhaniyi, timayambitsa kwambiri botolo la PET ngati chidebe chapulasitiki.
Mabotolo a PET ndi matumba apulasitiki opangidwa kuchokera ku PETzinthu zapulasitikikupyolera mu ndondomeko imodzi kapena ziwiri. Pulasitiki ya PET ili ndi mawonekedwe a kulemera kopepuka, kuwonekera kwambiri, kukana kwamphamvu komanso kosavuta kuthyoka.
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.
A. Botolo la mluza
B. Kuumba mluza wa botolo
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 ndi kutambasula ndi kuwomba, ndikuzichita pa makina awiri nthawi zosiyanasiyana, zomwe zimadziwikanso kuti jekeseni wotambasula ndi kuwomba. Chinthu choyamba ndikugwiritsa ntchito makina opangira jekeseni kuti mulowetse preform. Gawo lachiwiri ndikubwezeretsanso kutentha kwa chipinda ndikutambasula ndikuwuphulitsa mu botolo. Ubwino wa njira ziwirizi ndikugula preform ya 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
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, PVC nthawi zambiri imakhala yowonekera, kapena yamitundu ndi yowonekera, yowoneka bwino, ndipo mitundu yolimba siyigwiritsidwa ntchito kawirikawiri. Mabotolo a PET amathanso kupopera. Pansi pa botolo lopangidwa ndi nkhonya pali malo opindika. Kuwala kwambiri pansi pa kuwala. Pali mzere womangirira pansi pa botolo lobayidwa ndi nkhonya.
4. Kufananiza
Zopangira zazikulu zofananira zamabotolo 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 tona), chivundikiro chamutu cha mpope (omwe amagwiritsidwa ntchito ngati mafuta odzola), zipewa zoyandama, zipewa (zotchinga ndi zipewa zoyandama zimagwiritsidwa ntchito kwambiri pamizere yayikulu yamankhwala tsiku lililonse), ndi zina.
Kugwiritsa ntchito
Mabotolo a PET amagwiritsidwa ntchito kwambiri pamakampani opanga zodzoladzola,
makamaka m'makampani ochapira ndi kusamalira,
kuphatikiza shampoo, mabotolo a gel osambira, tona, mabotolo ochotsa zodzoladzola, ndi zina.
zonse zikuwombedwa.
Kuganizira za kugula
1. PET ndi imodzi yokha mwa zipangizo zomwe zilipo kwa mabotolo owombera. Palinso mabotolo a PE (ofewa, mitundu yolimba kwambiri, nthawi imodzi), mabotolo a PP (olimba, mitundu yolimba kwambiri, kupanga nthawi imodzi), mabotolo a PETG (mawonekedwe bwino kuposa PET, koma osati kawirikawiri). amagwiritsidwa ntchito ku China, mtengo wapamwamba, zinyalala zambiri, kupanga nthawi imodzi, zinthu zosasinthika), mabotolo owombera a PVC (ovuta, osakonda zachilengedwe, osawoneka bwino kuposa PET, koma owala kuposa PP ndi PE)
2. Zida za sitepe imodzi ndizokwera mtengo, zida ziwiri ndizotsika mtengo
3. PET botolo nkhungu ndi zotsika mtengo.
