Chii chinonzi pet? -Kunyatsoongorora kwePolyethyle terephthalate
Pet, kana Polyethlene Terephthalate, chinhu chePolymer chinoshandiswa zvakanyanya muindasitiri yemakemikari. Munyaya ino, isu tichapa ongororo yakadzama yedudziro yechipfu, nzvimbo dzayo dzekushandisa, maitiro ekugadzira nezvakanakira, kuti vape vaverengi nekunzwisisa kwakazara kwezvinhu zvakakosha.
Tsanangudzo uye zvakakosha zvivakwa zvePET
Chii chinonzi pet? Chemical, pet inonzi Thermer Polymer yakaumbwa nePolymerisation yeTerephthaal Acid uye ethylene glycol manhamba akanyanya kuita sesimba rakanyanya, kupisa. Izvi zvivakwa zvinoita kuti chipfuke chechikwaniriso chezvisarudzo mune zvakawanda zvekushandisa zviitiko, kunyanya muchikamu chekutakura.
Nzvimbo huru dzekushandisa dzePET
Pet inoshandiswa mune dzakasiyana siyana dzekushandisa, kutarisa pane mbiri huru nzvimbo: kurongedza zvinhu uye kugadzira fiber kugadzira. Muindasitiri wekutakura Zvipfeko zvakagadzirwa kubva kuPolyester machira zvakaoma-kupfeka, zviri nyore kugeza uye nekukurumidza kuoma, zvichiita kuti ive yakakodzera kupfeka kwemazuva ese.
Maitiro ekugadzira peturu
Kunzwisisa kuti chii chinodawo chipfuyo zvakare kutarisa maitiro ayo ekugadzira, ayo anoitwa nenzira mbiri huru: imwe-nhanho (yakananga estation) uye maviri-nhanho (ester exchange). Mune imwe-nhanho maitiro, terephthaal acid inoitwa zvakananga neEtlelane Glycolane yekugadzira peturu, uye chigadzirwa chekupedzisira chinoda kuiswa munzvimbo dzinotevera, sekuparadza, kurova-kuumba, kana jekiseni-kuumbwa, kuitira kuti ugadzire chigadzirwa chakaumbwa.
Zvakanakira uye kusimba kwechipfu
Chii chinonzi pet? Kubva pane yakagadzirirwa maonero, zvakanakira mhuka peturu ndedzekuita kwayo kwakanaka. Zvigadzirwa zvePeturu zvinogona kudzoreredzwa kuburikidza nePyrolysis, dzimwe nzira dzekudzora kusvibiswa kwezvakatipoteredza, uye simba repamusoro-siyana uye zvivakwa zvinoremerwa zvinozvipa mukana mukudzora kushandiswa kwemidziyo uye kwekufambisa. Aya maitiro anoita chipfuyo chimwe chezvinhu zvakakosha zvegirinhi zvinhu muindasitiri yazvino.
Mhedziso
Kupfupisa, chii chipfuyo? Iyo yakakwira-polymer polymer zvinhu zvine huwandu hwepanyama.Pepa hunoita basa rakakosha Kunyangwe iri muchirongwa chekutakura muhupenyu hwezuva nezuva Naizvozvo, kunzwisisa kwakadzama kwei peturu kwakakosha kuti unzwisise maitiro emakemikikiti emazuva ano.
