Makristalo oyera kapena ufa woyera wa kristalo, wosungunuka m'madzi, mowa ndi zosungunulira zina zachilengedwe. Yankho lake lamadzi ndi acidic
1,2,3,4-Butanetracarboxylic acid (BTCA) Ndi chinthu chabwino kwambiri chomaliza chosindikizira cholimba (DP) chopanda formaldehyde. Chili ndi zochita zambiri komanso fungo loipa. Nsalu monga thonje ndi silika, zomwe zimapangidwa ndi BTCA, zimatha kukhala ndi mphamvu monga kuletsa kuuma, kukanikiza kosatha komanso kusunga mawonekedwe ake ndipo zimakhala zolimba kwambiri.
BTCA ingagwiritsidwe ntchito pokonzekera zinthu za polyimide. Zinthu zamtunduwu zimakhala ndi mphamvu yabwino kwambiri yolimbana ndi kutentha, asidi, hydrocarbon komanso mphamvu zabwino zotetezera magetsi, ndipo zingagwiritsidwe ntchito pokonzekera zinthu zosiyanasiyana zogwira ntchito za polima, monga zinthu zowunikira kuwala, zinthu za polima zamankhwala komanso zinthu zogwira ntchito za nembanemba ya polima. Ingagwiritsidwe ntchito pokonzekera mphete zotetezera magetsi, zokutira waya ndi zinthu zotetezera magetsi.
Chikwama cha pepala chopangidwa ndi zinthu zosiyanasiyana cha 25kg chopangidwa ndi ku Poland - nsalu ya thonje kapena malinga ndi zomwe kasitomala akufuna.
Malo Osungira:
Sungani pamalo ouma komanso opanda mpweya. Nthawi yake yopuma ndi miyezi 12. Ikhoza kugwiritsidwabe ntchito ngati yatha.
Mayendedwe:
Pewani kutentha kwambiri komanso kupsa ndi dzuwa pamene mukunyamula.
