Polyester chips CZ-302
Type
"JADE" Brand, Copolyester.
Tsanangudzo
"JADE" Brand Copolyester "CZ-302" bhodhoro giredhi polyester machipisi ane yakaderera heavy metal content, yakaderera yemukati acetaldehyde, yakanaka ruvara kukosha, yakagadzikana viscosity.Iine yakasarudzika nzira yekubikira uye yepamberi yekugadzira tekinoroji, chigadzirwa chine yakanakisa kugadzirisa maficha, yakadzika yekushisa tembiricha, yakafara scope mukugadzirisa, yakanakisa kujeka uye yakakwirira muyero yechigadzirwa.Mukugadzira mabhodhoro, chigadzirwa chine kuderera kudiki uye kuderera kweacetaldehyde.Kunyange ichivimbisa kuchengeteka uye hutsanana, inogona kunyatso chengetedza kuravira kwakasiyana kwemvura yakacheneswa, mvura yemamineral uye mvura yakasvibiswa.
Applications
Iwo akakodzera kugadzira mabhodhoro ekurongedza emvura yakachena, chaiyo yemaminerari mvura, yakanyungudutswa mvura, mvura yekunwa, inonhuwira uye zvihwitsi midziyo, bhodhoro remakeup uye PET sheet zvinhu.
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 275-293°C.
