Tikatenga botolo la shampu lomwe limagwiritsidwa ntchito kwambiri, pansi pa botolo padzakhala chizindikiro cha PET, zomwe zikutanthauza kuti mankhwalawa ndi botolo la PET. Mabotolo a PET amagwiritsidwa ntchito kwambiri mumakampani ochapira ndi kusamalira, makamaka okhala ndi mphamvu zambiri.
Tanthauzo la Zamalonda
Mabotolo a PET amapangidwa ndiPulasitiki ya PETndipo amakonzedwa kudzera mu njira imodzi kapena ziwiri kuti apeze zotengera zapulasitiki.
Pulasitiki ya PET ili ndi mawonekedwe opepuka, owonekera bwino, osagwirizana ndi kugwedezeka komanso osavuta kuswa.
Njira zopangira
1. Kumvetsetsa preform
Choyambirira ndi chinthu chopangidwa ndi jakisoni. Monga chinthu chomalizidwa pang'ono cha biaxial stretch blowing, bottleneck ya preform yamalizidwa panthawi yopangira jakisoni, ndipo kukula kwake sikudzasintha panthawi yotenthetsera ndi kutambasula/kuwomba. Kukula, kulemera, ndi makulidwe a khoma la preform ndi zinthu zomwe tiyenera kuziganizira kwambiri tikamawomba mabotolo.
Kapangidwe ka preform
Kukonzekera koyambirira
2. Kuumba mabotolo a PET
Njira imodzi
Njira yomaliza jakisoni, kutambasula ndi kupukusa mu makina amodzi imatchedwa njira imodzi. Njira imodzi ndi kuchita kutambasula ndi kupukusa pambuyo poti preform yazizidwa pambuyo popanga jakisoni. Ubwino wake waukulu ndi kusunga mphamvu, kugwira ntchito bwino, kusagwira ntchito ndi manja komanso kuchepetsa kuipitsa.
Njira ya magawo awiri
Njira ya magawo awiri imalekanitsa kupangira jakisoni ndi kukanda ndi kukanda ndipo imachita izi pamakina awiri nthawi zosiyanasiyana. Imatchedwanso njira yopangira jakisoni. Gawo loyamba ndikugwiritsa ntchito makina opangira jakisoni kuti mupange jakisoni. Gawo lachiwiri ndikutenthetsanso preform kutentha kwa chipinda ndikukanda ndi kukanda mu botolo. Ubwino wa njira ya magawo awiri ndikuti preform ikhoza kugulidwa kuti ipangidwe jakisoni. Imatha kuchepetsa ndalama (talente ndi zida). Kuchuluka kwa preform ndi kochepa kwambiri kuposa kwa botolo, komwe ndikosavuta kunyamula ndi kusungira. Preform yopangidwa nthawi ya tchuthi imatha kukanda mu botolo nthawi yachilimwe.
3. Njira yopangira mabotolo a PET
三、Zinthu ndi kapangidwe kake
1. Zinthu za PET
PET, polyethylene terephthalate, yotchedwa polyester. Dzina la Chingerezi ndi Polyethylene Terephthalate, lomwe limapangidwa ndi polymerization reaction (condensation) ya zinthu ziwiri zopangira mankhwala, terephthalic acid PTA (terephthalic acid) ndi ethylene glycol EG (ethylicglycol).
2. Chidziwitso chodziwika bwino chokhudza botolo la mkamwa
Mlomo wa botolo uli ndi mainchesi a Ф18, Ф20, Ф22, Ф24, Ф28, Ф33 (ofanana ndi kukula kwa T kwa mlomo wa botolo), ndipo kufotokozera kwa ulusi nthawi zambiri kumatha kugawidwa m'magulu awa: 400, 410, 415 (ofanana ndi chiwerengero cha kutembenuka kwa ulusi). Kawirikawiri, 400 ndi kutembenuka kwa ulusi umodzi, 410 ndi kutembenuka kwa ulusi 1.5, ndipo 415 ndi kutembenuka kwa ulusi kawiri.
3. Botolo lokhala ndi thupi
Mabotolo a PP ndi PE nthawi zambiri amakhala ndi mitundu yolimba, zinthu za PETG, PET, PVC nthawi zambiri zimakhala zowonekera bwino, kapena zowonekera bwino, zokhala ndi mawonekedwe owoneka bwino, ndipo mitundu yolimba imagwiritsidwa ntchito kawirikawiri. Mabotolo a PET amathanso kupopedwa. Pali kadontho kozungulira pansi pa botolo lopangidwa ndi blow-mold. Limakhala lowala kwambiri pansi pa kuwala. Pali mzere wolumikizira pansi pa botolo lolowetsedwa ndi blow-mold.
4. Zowonjezera zothandizira
Zipangizo zazikulu zothandizira mabotolo opukutira ndi mapulagi amkati (omwe amagwiritsidwa ntchito kwambiri pazinthu za PP ndi PE), zipewa zakunja (zomwe zimagwiritsidwa ntchito kwambiri pa PP, ABS ndi acrylic, komanso zopakidwa ndi electroplated, ndi aluminiyamu yopakidwa ndi electroplated, zomwe zimagwiritsidwa ntchito kwambiri pa ma toners opopera), zophimba zakunja za mutu wa pampu (zomwe zimagwiritsidwa ntchito kwambiri pa zinthu zodzola ndi mafuta odzola), zipewa zoyandama, zipewa zoyatsira (zipewa zoyatsira ndi zipewa zoyandama zimagwiritsidwa ntchito kwambiri pazingwe zamagetsi zatsiku ndi tsiku), ndi zina zotero.
Mapulogalamu a Makampani
Mabotolo a PET amagwiritsidwa ntchito kwambiri mumakampani opanga zodzoladzola, makamaka mumakampani oyeretsa, kuphatikizapo shampu, mabotolo a shawa, toner, mabotolo ochotsera zodzoladzola, ndi zina zotero, zomwe zonse zimapangidwa ndi kupopedwa ndi kupangidwa.
Zoganizira Zogula
1. Mabotolo opukutira amatha kupangidwa ndi zinthu, PET ndi imodzi mwa izo, palinso mabotolo opukutira a PE (ofewa, mitundu yolimba, kupanga kamodzi), mabotolo opukutira a PP (olimba, mitundu yolimba, kupanga kamodzi), mabotolo opukutira a PETG (owonekera bwino kuposa PET, koma sagwiritsidwa ntchito kawirikawiri ku China, okwera mtengo, zinyalala zambiri, kupanga kamodzi, zinthu zosagwiritsidwanso ntchito), mabotolo opukutira a PVC (olimba, osawononga chilengedwe, osawonekera bwino kuposa PET, koma owala bwino kuposa PP ndi PE)
2. Zipangizo zoyendera sitepe imodzi ndi zodula, zoyendera sitepe ziwiri ndi zotsika mtengo
3. Botolo la PETnkhungu ndi zotsika mtengo.
4. Mavuto ndi mayankho abwino omwe amapezeka kawirikawiri, onani kanemayo
