Nekufambira mberi kuri kuita tekinoroji yekugadzira machira, fiber itsva dzakawanda dzava zvinhu zvekugadzira machira. Nhasi, ndichakuudzai zvakanyanya nezve tekinoroji yekuziva fiber yepolyester yakadzokororwa.
Zvinonzwisisika kuti munguva yakapfuura, nekuda kwekushaikwa kwenzira dzekuongorora uye kusakwanisa kwemasangano ekuyedza kuburitsa mishumo yemhando, mabhizinesi aisakwanisa kunakidzwa nemitemo yenyika yakakodzera, uye panguva imwe chete zvakakonzera kuvhiringidzika pakunyorwa kwezvimwe zvigadzirwa zvepolyester.
Chii chinonzi fiber yepolyester (PET) inoshandiswazve?
Kureva kuti, zvinhu zvemachira zvepolyester (PET) polymer uye zvepolyester (PET) zvinodzokororwazve uye zvinogadziriswa kuita polyethylene terephthalate fiber.
Mumashoko evanhuwo zvavo, fiber yepolyester yakadzokororwa (inozonzi polyester yakadzokororwa) inoreva polyester yakadzokororwa (yakadai semabhodhoro, furo, sirika, marara, machira, nezvimwewo) inogadzirwa nenzira dzekudzokorodza. Fiber yeEster.
Nheyo yeKuzivikanwa
Zvichibva pamusiyano mukuru uripo pakati pekugadzirisa polyester yakadzokororwa uye virgin polyester, izvo zvinoguma nehunhu hwakasiyana, sampuro inogadziriswa zvichienderana nemamiriro akatarwa uye inoedzwa pa chromatograph yemvura inoshanda zvakanyanya. Zvichienderana nemusiyano uripo munzvimbo yepamusoro yesampuro pasi penguva dzakasiyana dzekuchengetedza, Kuti uwane chinangwa chekuzivikanwa kwemhando yepamusoro.
Danho rekuzivikanwa
1. Methanolysis
2. Kubvisa Kuzvimba
3. Kuonekwa kwechromatography yemvura inoshanda zvakanyanya
Zvinwiwa zvinoshandiswa muchikamu 1 ne2 zviri pamusoro apa zvinoongororwa kuti zvionekwe nechiedza chemhando yepamusoro chechromatography.
4. Kugadziriswa kwedata uye kuzivikanwa kwaro
Polyester yakadzokororwa inokonzera shanduko muhuwandu uye kupararira kwe macromolecular heterogeneous chain links uye oligomers panguva yekugadzirira, izvo zvinogona kushandiswa sehwaro hwekuzivikanwa kwe polyester yakadzokororwa uye virgin polyester.
Ruzivo rwenzvimbo chaiyo ine kukwirira uye hunhu hwepamusoro hwayo zvinoratidzwa mutafura iri pazasi.

Tarisa kune ramangwana
Nekuwedzera kwekushandiswa kwepolyester uye kuziva kwevanhu nezvekuchengetedzwa kwezvakatipoteredza, kutarisisa kuri kuramba kuchiwedzerwa pakudzokororwa kwemarara epolyester. Kushandiswa kwemarara epolyester kugadzira fiber yepolyester yakadzokororwa kunogona kuderedza mitengo, kuderedza kushandiswa kwemafuta, uye kuvandudza mabhenefiti ehupfumi, izvo zvakakosha zvikuru mukusimudzira indasitiri yefiber yemakemikari.
Panguva imwe chete, nekuwedzera kwehuwandu hwepolyester yakadzokororwa, nyaya yekutsiva polyester yakadzokororwa uye virgin polyester yave kukwezva kutariswa kwakawanda kubva kuindasitiri. Kuwanda kwemitengo yezvinhu zviviri izvi kunoratidzawo hukama hwakanaka, uye kuonekwa kwemusiyano uripo pakati pezviviri izvi Tekinoroji iri kuwedzera kutariswa.
