Melamine Kumangirira Compound Kwa Firiji Chakudya Bokosi
Zopangira zopangira mbale ndizoyeramelamine ufa. Mapangidwe a Melamineamapangidwa ndi melamine ndi formaldehyde ndipo alibe poizoni.Ndi utomoni wa thermosetting.Choncho, melamine akamaumba pawiri akhoza kuumbidwa mu crockery pa kutentha kwambiri.Ichi ndi thermosetting pawiri kuti amapereka mitundu yosiyanasiyana.Gululi lili ndi mawonekedwe apamwamba a zinthu zowumbidwa, momwe kukana kwa mankhwala ndi kutentha kumakhala kwabwino kwambiri.Kuphatikiza apo, kuuma, ukhondo ndi kulimba kwa pamwamba ndi zabwino kwambiri.Imapezeka mu ufa wa melamine ndi mawonekedwe a granular, komanso mitundu yosinthidwa ya melamine ufa wofunidwa ndi makasitomala.
Katundu:
Melamine akamaumba pawiri mu mawonekedwe a ufa amachokera ku melamine-formaldehydeutomoni wolimbitsidwa ndi ma cellulose apamwamba kwambiri komanso kusinthidwanso ndi zochepa zowonjezera zowonjezera, utoto, zowongolera machiritso ndi mafuta.
Ubwino:
1. Kukongola kokongola, mtundu wokhazikika ndi kunyezimira, mitundu yosiyanasiyana, kusankha.
2. Easy fluidity ndi zovuta fluidity kukwaniritsa zosowa akamaumba.
3. Makina abwino amakina, kukana kwamphamvu, osalimba komanso kumaliza bwino.
4. Kutentha kwambiri kwamoto komanso kutentha kwabwino komanso kukana madzi.
5. Zopanda poizoni, zopanda fungo, zimakwaniritsa zofunikira zachitetezo cha chilengedwe ku Europe.
Mapulogalamu:
1. Zakumwa zam'kamwa: monga mbale, makapu, saucers, ladle, spoons, mbale ndi saucers, etc.
2. Zosangalatsa: monga ma dominoes, dayisi, mahjong, chess, ndi zina.
3. Zofunika tsiku ndi tsiku: monga thireyi, mabatani, zinyalala, chivundikiro cha chimbudzi.
Posungira:
Kusungirako pa 25 centigrade kumapereka bata kwa miyezi 6.Pewani chinyezi, litsiro, kuwonongeka kwa ma phukusi, ndi kutentha kwakukulu komwe kumakhudza kayendedwe kazinthu ndi mphamvu yake ya nkhungu.
