Chikwama cha tiyi cha PLA chomwe chimawola mphamvu ya chimanga chosungunuka ndi madzi

Matumba a pepala losefera tiyi nthawi zambiri amakhala ndi zinthu zotsatirazi, zomwe zimatha kusinthidwa malinga ndi zosowa zanu zenizeni.
1. Matumba a tiyi a chimanga ndi ulusi wopangidwa kuchokera ku chimanga, tirigu ndi starch zina ngati zinthu zopangira, zomwe zimasanduka lactic acid mwa kuwiritsa kenako n’kusinthidwa kukhala polymer ndi kupota. Ndi a ulusi womwe umamaliza kuyenda kwachilengedwe ndipo umatha kuwonongeka.
2. Chikwama cha tiyi cha PP chosalukidwa ndi zinthu zopangidwa ndi PP ndi polypropylene, yomwe ndi polima yoyera yoyera kwambiri yopanda poizoni, yopanda fungo, komanso yopanda kukoma ngati mkaka. PP polyester ndi mtundu wa amorphous, malo ake osungunuka ayenera kukhala opitirira 220, ndipo kutentha kwake kuyenera kukhala pafupifupi madigiri 121.
3. Ubwino wa matumba a tiyi a PET osalukidwa ndi PET ngati zinthu zopakira ndi: kukana kutentha kwambiri, kugwiritsa ntchito kutentha kwa nthawi yayitali pa kutentha kwa 120 °C, komanso kukana kutentha kwa 150 °C kwa kanthawi kochepa; kosakhala poizoni, kopanda kukoma, Ukhondo wabwino komanso chitetezo, zitha kugwiritsidwa ntchito mwachindunji popakira chakudya.
4. Zipangizo zosefera Pali njira zambiri zogwiritsira ntchito mapepala osefera m'matumba a tiyi ndi moyo. Pepala losefera la khofi ndi limodzi mwa iwo. Pepala losefera lomwe lili pa thumba la tiyi limapereka kufewa kwambiri komanso mphamvu yonyowa kwambiri. Mapepala ambiri osefera amapangidwa ndi ulusi wa thonje. Chifukwa chakuti zinthu zake zimapangidwa ndi ulusi, pali mabowo ang'onoang'ono ambiri pamwamba pake kuti tinthu tamadzimadzi tidutse, pomwe tinthu tating'onoting'ono tomwe timakula sitingadutse.
5. Chikwama cha tiyi cha pepala Chimodzi mwa zinthu zopangira zomwe zimagwiritsidwa ntchito mu thumba la tiyi la pepala ili ndi abaca, lomwe ndi lopepuka komanso lopyapyala ndipo lili ndi ulusi wautali. Pepala lopangidwa ndi lolimba komanso lokhala ndi mabowo, zomwe zimapangitsa kuti kukoma kwa tiyi kufalikire. Chinthu china chopangira ndi ulusi wa pulasitiki wotseka kutentha womwe umagwira ntchito yotseka thumba la tiyi. Pulasitiki iyi siyamba kusungunuka mpaka itatenthedwa kufika pa 160°C, kotero sikophweka kufalikira m'madzi. Ndikukhulupirira kuti izi zikuthandizani, zikomo.
