ZINTHU ZOSAVUTA POLYESTER AMATIPATSA ZINTHU:
Zina zazikulu za unsaturated polyester resins ndi monga: Zamadzimadzi, mu ntchito yawo:
● Kuchepa kwa mzere wochepa.
● Kunyowa kwabwino kwa ulusi ndi ma charger.
● Kulumikiza kozizira powonjezera chowumitsa.
● Kuchepetsa zotsatira za sagging mu ofukula stratification (thixotropic katundu).
Zolimba, pambuyo polumikizana:
● Kupepuka kwapadera.
● Kusasunthika.
● Kutsekereza magetsi kwabwino.
● Kukhazikika kwa dimensional motsutsana ndi kusintha kwa kutentha.
● Kuchuluka kwamphamvu / kulemera kuposa chitsulo.
● Kusamva mankhwala.
● Kumaliza kwapamwamba kwambiri.
● Kupewa madzi.
● Kusamva kuvala komanso kutentha kwambiri.
● Kukana kwa makina abwino.
NTCHITO ZA POLYESTER ZOSAVUTA ZONSE:
Ntchito za unsaturated polyester resin ndizosiyanasiyana.Utomoni wa polyester umayimira chimodzi mwazinthu zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana.Zofunikira kwambiri, komanso zomwe zafotokozedwa pamwambapa, ndi:
● Zinthu zophatikizika.
● Utoto wamatabwa.
● Makapu a laminated, malata, nthiti.
● Chovala cha gel pamabwato, magalimoto ndi mabafa.
● Zopaka utoto, zodzaza, zomangira, zomangira ndi zoyikapo mankhwala.
● Zida zophatikizika zozimitsa zokha.
● Quartz, marble ndi simenti yopangira.
