Tsanangudzo
"JADE" Brand Copolyester "CZ-318" bhodhoro giredhi polyester machipisi ane yakaderera heavy metal content, yakaderera yeacetaldehyde, yakanaka ruvara kukosha, yakagadzikana viscosity.Iine yakasarudzika nzira yekubikira uye tekinoroji yekugadzira yepamberi, chigadzirwa chine kujeka kwakanakisa uye chinogona kugutsa zvakakora uye akawanda marudzi ekugadzirisa zvinodiwa zvemabhodhoro emafuta anodyiwa, mabhodhoro edoro, mabhodhoro emishonga nemashiti, ane zvimiro zvekushisa kwakadzika, zvakafara. chiyero mukugadzirisa, kujeka kwakanakisa, kusimba kwepamusoro uye yakakwirira yakapedzwa chigadzirwa.
Applications
Inogadzirwa uye inogadzirwa maererano nepamusoro pesimba, kuparadzaniswa, kujeka uye zviri nani kugadzirisa chimiro nezvimwe zvakakosha kushandisa zvivakwa zvinodiwa nemabhodhoro ezvinwiwa zvekabhoni, mabhodhoro emafuta anodyiwa mabhodhoro edoro, mabhodhoro emishonga, mabhodhoro ekugezesa zvizorwa, mabhodhoro emusango. uye PET mapepa.
Mamiriro ekugadzirisa maitiro
Kuomesa kunofanirwa kusati kwanyungudutswa kudzivirira resin kubva kuhydrolysis.Mamiriro ekuomeswa akajairika imhepo tembiricha ye160-180 ° C, 4-6 maawa ekugara, tembiricha yedova iri pasi -40 ℃.Yakajairika mbiya tembiricha inenge 275-295°C.
