Namwali wamkulu wa namwali, ndi wouma ndikuwuma mpaka 400-ppm chinyezi asanachotse chomera. Kunyamula chinyezi mwachangu kwambiri, imatha kuyamwa pafupifupi 2000 ppm chinyezi cham'mimba ndipo mavuto ambiri omwe amakumana nawo chifukwa chosawuma. Play imayenera kuwuma bwino musanakonzedwe. Chifukwa ndi polymer, kukhalapo kwa chinyezi chochepa kwambiri panthawi yosungunula kumayambitsa kuwonongeka kwa maunyolo ndi kutaya kwa kulemera kwa masentimita. Pulogalamu imafunikira madigiri osiyanasiyana owuma malinga ndi kalasiyo komanso momwe idzagwiritsidwira ntchito. Wochepera 200 ppm ndibwino chifukwa ma viscy amakhala okhazikika komanso otsimikizira kuti ndi abwino.
Monga chiweto, namwali pulasitiki amatumizidwa kale. Ngati sichoncho, plag ikhala yomata komanso yotentha pomwe kutentha kwake kumafika 60 ℃. Iyi ndi kutentha kwa galasi la glass (TG); mfundo yomwe amorphous imayamba kufewetsa. . Ngati Crystallulesp Plaptal Plable Place Wowuma ndipo akuwonetsedwa motentha pamwamba pa 140 f, idzayambitsa zopingasa moopsa. Chifukwa chake, Crystallizer imagwiritsidwa ntchito kuti ilole kusintha kudzera pa TG mukamakhudzidwa.
Kenako pla imafunayani yowuma ndi crystalizele
1.
Mapulogalamu a BorHous ogwiritsidwa ntchito potentha zigawo zigawo m'mafilimu amawuma pa 60 ℃ kwa maola 4. Makulidwe a Crystallory omwe amagwiritsidwa ntchito ku pepala ndi filimuyo amawuma pa 80 ℃ kwa maola 4. Njira zokhala ndi nthawi yayitali kapena kutentha kwambiri ngati chinyezi chazitsulo chimafunikira kuyanika kwambiri, mpaka osakwana 50 ppm.
Kuphatikiza apo, owuma akhirtared amawuma - owuma a IR adawonetsedwa kuti akulira bwino inje. Kugwiritsa ntchito kuwuma (ir). Chifukwa cha kuchuluka kwakukulu kwa mphamvu ndi kuphika pakati ndi kutalika kwake komwe kumagwiritsidwa ntchito, ndalama zamagetsi zimatha kuchepetsedwa kwambiri, komanso kukula kwake.Kuyesedwa koyamba kwawonetsa kuti namwaliyo Indio Bipolyl akhoza kukhala wouma ndipo amorphous Flake adalira ndikuwuma mkati mwa mphindi 15 zokha
Makina owuma a Crystal
1. Ndi kukonza zouma komanso zokutira nthawi
2. Nthawi yowuma ndi 15-20mins (nthawi yowuma imatha kusinthidwa ngati njira ya makasitomala pazinthu zouma)
3. Kutentha kwanyengo kumatha kusintha (kuyambira 0-500 ℃)
4. Chinyezi chomaliza: 30-50ppm
5.
6.Pspace kupulumutsa: mpaka 300%
7.
8. Kuthamanga kuti muyambe
9. Kusintha Kwachangu ndi Kutseka Nthawi
Makonda a Pla (Polylactic acid) magwiridwe ali
Oletsedwa ndi ulusi: Matumba a Tiyi, zovala.
Kuumba jakisoni: Milandu yamitengo.
Zopanga: Ndi mtengo, pmma.
Thermofarm: Clamsals, ma trans cookie, makapu, nyemba za khofi.
Mabowo owumba: mabotolo amadzi (osakhala ndi kaboni), timadziti tomwe timadzitawa, mabowo odzikongoletsa.
