Polyester chips CZ-302
Type
"JADE" Brand, Copolyester.
Tsanangudzo
"JADE" Brand Copolyester "CZ-302" bhodhoro regiredhi repolyester machipisi ane yakaderera heavy metal content, yakaderera yeacetaldehyde, yakanaka ruvara kukosha, yakagadzika viscosity. Iine yakasarudzika nzira yekubikira uye tekinoroji yekugadzira yemhando yepamusoro, chigadzirwa chine akanakisa ekugadzirisa maficha, kuderera kwekushisa tembiricha, hupamhi hwekugadzirisa, yakanakisa kujeka uye yakakwirira mukuderera kwechigadzirwa chidiki, mukugadzira chigadzirwa chidiki. Acetaldehyde Ichiri kuchengetedza kuchengeteka uye utsanana, inogona kunyatso chengetedza kuravira kwakasiyana kwakasiyana kwemvura yakacheneswa, mvura ine mineral uye distilled mvura.
Applications
Iwo akakodzera kugadzira mabhodhoro ekurongedza emvura yakachena, chaiyo yemaminerari mvura, yakanyungudutswa mvura, mvura yekunwa, zvinonhuwirira uye zvihwitsi midziyo, bhodhoro remakeup uye PET sheet zvinhu.
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 275-293°C.
