PLA Chimanga Wowuma Biodegradable Tiyi Chikwama Chosefera Papepala Chikwama Chokhala Ndi Chingwe Chathonje

Matumba a mapepala a tiyi nthawi zambiri amakhala ndi zinthu zotsatirazi, zomwe zimatha kusinthidwa malinga ndi zosowa zanu zenizeni.
1. Matumba a tiyi wa chimanga ndi ulusi wopangidwa kuchokera ku chimanga, tirigu ndi zowuma zina monga zopangira, zomwe zimasandulika kukhala lactic acid ndi kupesa kenako ndi polymerized ndi kupota. Ndi ya ulusi womwe umamaliza kufalikira kwachilengedwe komanso uli ndi biodegradability.
2. Thumba la tiyi la PP losalukidwa ndi zinthu za pp ndi polypropylene, yomwe ndi polima yopanda poizoni, yopanda fungo, yopanda kukoma yamkaka yoyera kwambiri. PP polyester ndi mtundu wa amorphous, malo ake osungunuka ayenera kukhala pamwamba pa 220, ndipo kutentha kwake kwa kutentha kuyenera kukhala pafupifupi madigiri 121.
3. Ubwino wa matumba a tiyi a PET osalukidwa ndi PET monga zida zonyamulira ndi: kukana kwambiri kutentha kwambiri komanso kutsika, kugwiritsa ntchito nthawi yayitali kutentha kwa 120 ° C, komanso kukana kutentha kwa 150 ° C kwakanthawi kochepa- kugwiritsa ntchito nthawi; sanali poizoni, zoipa, Ukhondo wabwino ndi chitetezo, angagwiritsidwe ntchito mwachindunji ma CD chakudya.
4. Zosefera za pepala Pali ntchito zambiri za pepala losefera m'matumba a tiyi ndi moyo. Pepala losefera khofi ndi amodzi mwa iwo. Pepala la fyuluta pamtunda wakunja wa thumba la tiyi limapereka kufewa kwakukulu ndi mphamvu yonyowa kwambiri. Mapepala ambiri a fyuluta amapangidwa ndi ulusi wa thonje. Chifukwa chakuti zinthu zake n’zopangidwa ndi ulusi, pamwamba pake pamakhala timabowo ting’onoting’ono tosawerengeka kuti tinthu tamadzi timene tidutse, pamene tinthu tating’ono tokulirapo sitingathe kudutsamo.
5. Chikwama cha tiyi cha mapepala Chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito mu thumba la tiyi la pepalali ndi abaca, yopepuka komanso yopyapyala komanso yokhala ndi ulusi wautali. Pepala lopangidwa ndi lolimba komanso lopindika, zomwe zimapanga mikhalidwe yoyenera kufalitsa kukoma kwa tiyi. Chinthu chinanso ndi pulasitiki yotsekera kutentha yomwe imagwira ntchito kusindikiza thumba la tiyi. Pulasitiki imeneyi siyamba kusungunuka mpaka itatenthedwa kufika 160°C, choncho sikophweka kumwazikana m’madzi. Ndikukhulupirira kuti zikuthandizani, zikomo.
