Bhodhoro rakazadzwa-kupisa Giredhi PET Resin
Product Sumo
Kupisa-Yakazadzwa bhodhoro giredhi polyester machipisi akagadzirwa uye akagadzirwa zvakanyanya kune anopisa-kuzadza mabhodhoro zvinoenderana neicho chinwiwa chetii, zvinwiwa zvemichero-muto uye zvimwe zvinwiwa zvepakati zvinoda kuve zvinopisa bhodhoro kuti rizare.
Chigadzirwa chechigadzirwa chine yakaderera inorema simbi yemukati, yakaderera yemukati yeacetaldehyde, yakanaka ruvara kukosha, Yakagadzikana viscosity uye yakanaka yekugadzirisa.Iine rakasiyana muitiro resipi uye yepamusoro kugadzirwa michina, chigadzirwa, kana ari thermoformed muna SIPA, SIDEL, ASB etc. chokutanga mabhodhoro-kugadzira michina pasi zvakajairika mamiriro, ane yakakwirira tropism mwero, kugadzikana crystallinity uye zvakanaka fluidity pamwe yakaderera kushushikana-kusunungura mwero mu bhodhoro rose, kugadzikana kwekushisa kwekushisa kwekugadzirisa uye kupedzwa kwepamusoro kwechigadzirwa mukugadzira mabhodhoro, kunogona kugutsa zvinodiwa zvekuiswa mabhodhoro paanenge 90 ° C uye kudzivirira zvinwiwa kubva pakusvibiswa kana kuti oxidization munguva yekuchengetedza uye kudzivirira deformation yemabhodhoro.

Typical Processing Conditions
Kuomeswa kunodiwa kusati kwanyungudika kugadzirisa kudzivirira resin kubva kuhydrolysis.Mamiriro ekuomeswa akajairika imhepo tembiricha ye165-185 ° C, 4-6 maawa ekugara, tembiricha yedova iri pasi -40 0C.
Kupisa kwakajairika kwembiru kunosvika 285-298°C.
