Bhodhoro remvura Giredhi PET Resin (PET)
Product Sumo
Bhodhoro remvura giredhi repolyester machipisi akakodzera kugadzira mabhodhoro ekurongedza emvura yakachena, chaiyo yemaminerari mvura, yakadirwa mvura, mvura yekunwa, zvinonhuwirira uye zvihwitsi midziyo, bhodhoro remakeup uye PET sheet zvinhu nezvimwe.
Chigadzirwa chechigadzirwa chine yakaderera inorema simbi yemukati, yakaderera yemukati yeacetaldehyde, yakanaka kunaka 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.
