Tsanangudzo
"JADE" Brand Copolyester "CZ-318" giredhi remabhodhoro epolyester machipisi ane yakaderera heavy metal content, yakaderera yeacetaldehyde, yakanaka ruvara kukosha, yakagadzikana viscosity. Iine yakasarudzika nzira yekubikira uye tekinoroji yekugadzira, chigadzirwa chine kujeka kwakanyanya uye chinogona kugutsa zvakakora uye zvakawanda zvakasiyana-siyana zvekugadzirisa zvinodiwa zvemadiki-package emafuta anodyiwa, mabhodhoro emafuta anodyiwa, bhodhoro remafuta anodyiwa, mabhodhoro. yakaderera kugadzirisa tembiricha, yakafara chiyero mukugadzirisa, yakanakisa kujeka, kusimba kwepamusoro uye yakakwirira yakapedzwa chigadzirwa chiyero.
Applications
Inogadzirwa uye inogadzirwa maererano nepamusoro pesimba, kuparadzaniswa, kujeka uye zviri nani kugadzirisa chimiro nezvimwewo zvakakosha kushandisa zvivakwa zvinodikanwa nemabhodhoro ezvinwiwa zvekabhoni, diki-pakeji inodyiwa mafuta mabhodhoro edoro mabhodhoro, mabhodhoro emishonga, kugeza zvizorwa mabhodhoro 、 mhuka-muromo mabhodhoro uye PET mapepa.
Mamiriro ekugadzirisa maitiro
Kuomeswa kunodiwa kusati kwanyungudika kugadzirisa 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.
