Ndi Zida Ziti Zapulasitiki Zomwe Zili Zoyenera Pamakina Ang'onoang'ono a Multi-station Thermoforming?
PVC, PET, PS, monga zopangira, kusintha nkhungu pamakina amodzi kupanga lids, chimakwirira, thireyi, mbale, mabokosi, chakudya ndi trays zamankhwala, etc.
Polyvinyl chloride (PVC)
Polyvinyl kolorayidi, yofupikitsidwa monga PVC, ndi polima wopangidwa ndi ufulu kwakukulu mapolima polymerization wa vinilu kolorayidi monoma pansi zochita za intiators monga peroxides ndi mankhwala azo, kapena kudzera kuwala ndi kutentha kukhudzana. Zimawoneka ngati ufa woyera, wopanda poizoni komanso wopanda fungo, wokhala ndi kulemera kwa molekyulu kuyambira 50,000 mpaka 110,000 (ya PVC yoyera yopangidwa ndi mafakitale). Kachulukidwe wake wachibale ndi 1.35-1.45, kusonyeza mayamwidwe otsika madzi ndi mpweya permeability (yoyera PVC). Simasungunuka m'madzi, petulo, mowa, kapena vinyl chloride, koma imatha kusungunuka mu ma ketones, esters, ndi chlorinated hydrocarbon solvents. Polyvinyl chloride (PVC) imadzitamandira mwamphamvu kukana kwamankhwala ndipo ndi insulator yabwino yamagetsi; komabe, sizovuta kwambiri. Ndikofunikira kudziwa kuti zinthuzi sizikhazikika zikakumana ndi mpweya komanso kutentha, zomwe zimapangitsa kuti ziwonongeke.
Powonjezera zosintha zamphamvu ndi zokhazikika za malata ku PVC, kutsatiridwa ndi kusakaniza, kupanga pulasitiki, ndi kuwerengera, mapepala owonekera amapangidwa. Kupyolera mu thermoforming, imatha kupangidwa kukhala zotengera zowoneka bwino zokhala ndi mipanda yopyapyala kapena kugwiritsidwa ntchito ngati vacuum-formaging, yomwe imakhala ngati zopangira zabwino kwambiri komanso zokongoletsera.
mudzapeza PVC ponseponse chifukwa ndi yosagwira moto ndipo imagwira bwino kutentha. Yang'anani mwachangu: ngakhale imayima mwamphamvu motsutsana ndi mankhwala ambiri ndipo ndi insulator yabwino kwambiri yamagetsi, imatha kukhala yolimba ndipo sichimakhudza kwambiri. Zimakhudzidwanso ndi kukhudzidwa kwa nthawi yayitali ndi okosijeni ndi kutentha kwakukulu, zomwe zingapangitse kuti ziwonongeke.
Polyethylene Terephthalate (PET)
PET ndiye kavalo wamkulu wa mapulasitiki omveka bwino, olimba. Ngati mudakhalapo ndi botolo la soda kapena chidebe choyera cha chakudya, mumadziwa zomwe PET imamva: yoyera, yonyezimira, komanso yolimba. Ndizinthu zomwe zimapambana kwambiri pakuyika.
Izi ndi zomwe zimapangitsa kuti zikhale zothandiza kwambiri:
Mphamvu & Kumveka Bwino: Ndi yamphamvu modabwitsa komanso yosasunthika—yosamva mphamvu kuwirikiza ka 3 mpaka 5 kuposa mafilimu ena apulasitiki—ndipo imapinda popanda kufooka. Kuphatikiza apo, imakhala yowoneka bwino mwachilengedwe yokhala ndi gloss yokongola yomwe imapangitsa kuti zinthu ziziwoneka bwino.
Chotchinga Chachikulu: Imagwira ntchito yabwino kwambiri yosunga mpweya, chinyezi, ndi kununkhiza, chifukwa chake imapangitsa kuti chakudya chanu chikhale chatsopano komanso kuti soda yanu ikhale yosalala.
Yolimba & Yotetezeka: Imatha kutentha kuchokera ku -70 ° C mpaka 65 ° C osataya mphamvu zake. Imalimbananso ndi mafuta ndi mafuta, ndipo ndi yopanda poizoni komanso yotetezeka ku chakudya.
Kuteteza: Kumatchinga kuwala kwa ultraviolet, kuteteza zomwe zili mkati kuti zisawonongeke ndi dzuwa.
Polystyrene (PS)
Polystyrene imadziwika bwino m'njira ziwiri: pulasitiki yolimba, yowoneka bwino (monga ma CD) kapena ngati kutchinjiriza kwa thovu (Styrofoam™). Ndi chinthu chopepuka komanso chosunthika chomwe chimayamikiridwa chifukwa chomveka bwino komanso mphamvu zotchinjiriza.
Polystyrene ndi yopanda mtundu komanso yowoneka bwino, imavomereza mosavuta mtundu, ndipo imakhala ndi kachulukidwe kakang'ono koyerekeza ndi polypropylene (PP) ndi polyethylene (PE). Imawonetsa mphamvu zamagetsi zamagetsi, makamaka mawonekedwe apamwamba kwambiri, achiwiri pambuyo pa PTFE ndi PPO. Kuonjezera apo, kukhazikika kwake kwa kuwala ndi kwachiwiri kwa polymethyl methacrylate (PMMA), pamene kukana kwake kwa radiation ndikwamphamvu kwambiri pakati pa mapulasitiki onse. Chofunikira kwambiri cha polystyrene ndi kukhazikika kwake kwamafuta komanso kusuntha panthawi yosungunuka, zomwe zimapangitsa kuti zikhale zosavuta kuzikonza komanso zoyenera kupanga zambiri. Imawonetsa kutsika kwapang'onopang'ono komanso kukhazikika kwabwino kwazinthu zopangidwa.
Kuti muwone momwe zinthuzi zingapangidwire bwino kuti zikhale zomaliza, tikukupemphani kuti mudzakumane ndi Makina athu Ang'onoang'ono Opangira ma Thermoforming Machine . Ndi njira yaying'ono, yotsika mtengo kuti muyambitse mwachangu mzere wanu wopanga bwino.
Katswiri wopanga makina opangira kutentha.
