Chiyambi: Tikatenga botolo la shampu wamba, 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 ndipo nthawi zambiri amakhala ndi zinthu zambiri. M'nkhaniyi, tikuwonetsa makamaka botolo la PET ngati chidebe cha pulasitiki.
Mabotolo a PET ndi zotengera zapulasitiki zopangidwa kuchokera ku PETzinthu zapulasitikikudzera mu njira imodzi kapena ziwiri zokonzera. PET pulasitiki ili ndi kulemera kopepuka, kuwonekera bwino, kukana kugwedezeka komanso kosavuta 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.
A. Kapangidwe ka botolo la mluza
B. Kuumba botolo la mluza
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 jakisoni ndi kutambasula ndi kupukusa, ndipo imachita izi pamakina awiri nthawi zosiyanasiyana, zomwe zimadziwikanso kuti njira yotambasula ndi kupukusa jekeseni. Gawo loyamba ndikugwiritsa ntchito makina opangira jekeseni kuti mupukusa jekeseni. Gawo lachiwiri ndikutenthetsanso kutentha kwa chipinda ndikupukusa ndikupukusa mu botolo. Ubwino wa njira ya magawo awiri ndikugula preform yopangira blow molding. 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 kupukusa jekeseni mu botolo nthawi yachilimwe.
3. Njira yopangira mabotolo a PET
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, PETG, PET, PVC nthawi zambiri amakhala owonekera bwino, kapena amitundu yosiyanasiyana komanso owonekera bwino, okhala ndi mawonekedwe owoneka bwino, ndipo mitundu yolimba imagwiritsidwa ntchito kawirikawiri. Mabotolo a PET amathanso kupopedwa. Pali malo ozungulira pansi pa botolo lopangidwa ndi blow-mold. Limakhala lowala kwambiri pansi pa kuwala. Pali mzere wolumikizira pansi pa botolo lolowetsedwa ndi blow-mold.
4. Kufananiza
Zinthu zazikulu zomwe zimagwirizana ndi 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, zomwe zimagwiritsidwanso ntchito pa electroplated, ndi aluminiyamu yopangidwa ndi electroplated, zomwe zimagwiritsidwa ntchito kwambiri popopera toner), chivundikiro cha mutu wa pampu (chomwe chimagwiritsidwa ntchito kwambiri popaka essence ndi lotion), zipewa zoyandama, zipewa zoyatsira (zipewa zoyatsira ndi zipewa zoyandama zimagwiritsidwa ntchito kwambiri popaka mankhwala akuluakulu tsiku lililonse), ndi zina zotero.
Kugwiritsa ntchito
Mabotolo a PET amagwiritsidwa ntchito kwambiri mumakampani opanga zodzoladzola,
makamaka mu makampani ochapira ndi osamalira,
kuphatikizapo shampu, mabotolo a shawa, toner, mabotolo ochotsera zodzoladzola, ndi zina zotero.
onse aphulika.
Zoganizira zogula
1. PET ndi chimodzi mwa zinthu zomwe zikupezeka pa mabotolo opukutira. 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 kuposa PP ndi PE)
2. Zipangizo zoyendera sitepe imodzi ndi zodula, zida zoyendera sitepe ziwiri ndi zotsika mtengo
3. Mabotolo a PET ndi otsika mtengo.
