Type
"JADE" Brand , homopolyester.
Tsanangudzo
"JADE" Brand homopolyester "CZ-333" bhodhoro giredhi polyester machipisi ane yakaderera heavy metal content, yakaderera yeacetaldehyde, yakanaka ruvara kukosha, Yakagadzikana viscosity uye yakanaka yekugadzirisa. Iine rakasiyana muitiro resipi uye yepamusoro kugadzirwa michina, chigadzirwa, kana ari thermoformed mu SIPA, SIDEL, ASB etc. okutanga mabhodhoro-kugadzira michina pasi zvakajairika mamiriro, ane yakakwirira tropism mwero, kugadzikana crystallinity uye zvakanaka fluidity ine yakaderera-kusunungura mwero mu iyo bhodhoro rose, yakagadzikana yekushisa kwekudzivirira kwehuwandu uye yakakwirira yakapedzwa chigadzirwa mukugadzira mabhodhoro, inogona kugutsa zvinodiwa zvekuiswa mabhodhoro paanenge 90 ° C uye kudzivirira zvinwiwa kubva pakusvibiswa kana oxidization munguva yekuchengetedza uye kudzivirira deformation yemabhodhoro.
Applications
anonyanya kushandiswa kupisa-kuzadza mabhodhoro maererano nezvinwiwa zvetii, zvinwiwa zvemichero-muto uye zvimwe zvinwiwa zvepakati zvinoda kuve unopisa mubhodhoro rekuita sterilization.
Mamiriro ekugadzirisa maitiro
Kuomesa kunofanirwa kusati kwanyungudutswa kudzivirira resin kubva kuhydrolysis. Mamiriro ekuomeswa akajairika imhepo tembiricha ye165-185 ° C, 4-6 maawa ekugara, tembiricha yedova iri pasi -40 ℃. Kupisa kwakajairika kwembiru kunosvika 285-298°C.
