Nhanganyaya kuPolyesterKusefa kweFiber
Fiber yepolyester ndeimwe yefiber dzakakosha kwazvo pasi rose, ichiumba musimboti wemaindasitiri akasiyana-siyana kubva kumafashoni kusvika kumachira emaindasitiri. Simba rayo, kugara kwenguva refu, uye kushanda kwayo zvakanaka zvinoita kuti ive sarudzo yepamusoro yemachira, upholstery, makapeti, uye kunyange mashandisirwo ehunyanzvi. Zvisinei, kuwana fiber yepolyester yemhando yepamusoro hakusi kwega. Inoda kudzorwa kwakaringana padanho rega rega rekugadzira, uye chinhu chimwe chinowanzo furatirwa asi chakakosha ndechekutikusefa.
Kusefa kunoshanda semuchengeti wemhando yefaibha. Kubva pakugadzirira zvinhu zvakabikwa kusvika pakunyunguduka kwepolymer, zvinhu zvinosvibisa zvinogona kupinda chero nguva. Kunyangwe tsvina isingaonekwe zvakanaka ine simba rekugadzirisa mashandiro efaibha, zvichikonzera kusimba kusina simba, kudhaya kusina kufanana, kana kumira kugadzira kunodhura nekuda kwekuputsika kwe spin. Midziyo yefaibha yemazuva ano haigone kubhadhara kusashanda zvakanaka kwakadaro, ndosaka kusefa kwepamusoro kwave chinhu chinoshanda.zvinodiwa pakugadzirisa hurongwa.
Nei Kusefa Kwakakosha MuPolyesterKugadzirwa kweFiber
Kuti unzwisise kuti sei kusefa kwakakosha kudaro, fungidzira kugadzirwa kwepolyester secheni. Chinongedzo chimwe nechimwe—zvinhu zvisina kugadzirwa, esterification, polymerization, spinning—chinofanira kusimba kuti cheni ive yakavimbika. Chinongedzo chimwe chete chisina kusimba, senge kusvibiswa kwezvinhu zvisina kugadzirwa kana magels mupolymer yakanyunguduka, chinogona kukanganisa maitiro ese.
Kusefa kunovimbisa:
•Kusachinja-chinja- fibers dzine simba rakafanana, magadzirirwo, uye dhayi inotorwa zvakafanana.
•Kuvimbika- kuzorora kushoma uye nguva shoma yekuzorora.
•Kushanda zvakanaka- nguva refu yekusefa uye kuderedzwa kwekuchengetedzwa kwayo.
•Kuwana purofiti- mabasa akachena anoreva kuderedza marara nemitengo.
Muchidimbu, kusefa hakusi kungobvisa zvidimbu chete; asi ndekwekubvisakugadzirisa kugadzirwa kwesenharaundakuti zvive zvakanaka uye kuti zvinobudirira.
KunzwisisaPolyesterKugadzirwa kweFiber
Kugadzirwa kwefibers dzepolyester kunosanganisira matanho akati wandei akabatana:
1. MbichiKugadzirira Zvinhu:Terephthalic acid (TPA) kana dimethyl terephthalate (DMT) inosanganiswa ne ethylene glycol (EG).
2. Kugadziriswa kwechiedza/Kuchinja maester:Kusangana kwemakemikari kunogadzira ester iri pakati.
3. Kuwanda kwemvura inodziya:Maketeni marefu epolymer anoumba polyethylene terephthalate (PET).
4. Kunyungudutsa Kutenderera:PET yakanyungudutswa inoburitswa kuburikidza nemaspinnerets kuita filaments.
5. Kudhirowa & Kugadzira Magadzirirwo:Fiber dzinotambanudzwa uye dzinogadziriswa kuti dziwane hunhu hwaunoda.
Padanho rega rega, zvinhu zvinosvibisa—zvingava guruva, majeli, kana ma catalyst residues—zvinogona kukanganisa kushanda zvakanaka. Semuenzaniso, ma agglomerates ari muTiO₂ additives anogona kuvharira spinnerets, kana majeli ari mu melt anogona kuderedza simba re fiber. Kusefa kunodzivirira njodzi idzi, zvichiita kuti mutsetse wekugadzira uve wakanyatsonaka uye kubuda kwacho kurambe kuri kwepamusoro.
MbichiKusefa Zvinhu: Kuvaka Nheyo Yakasimba
Danho rekutanga rekuona kuti fiber yakanaka ndeyekusefa zvinhu zvakaita seTPA, EG, catalysts (Sb₂O₃), uye TiO₂ additives. Kana zvikasasefa, izvi zvinounza tunhu tunokonzera matambudziko: mafirita epolymer akavharika, hupenyu hupfupi hwemafirita, uye fiber dzisina kusimba.
Kusefa Munguva yeEsterification
Kugadziriswa kwesimbi inhanho inonetsa apo tsvina inowanzo umbwa. Sezvo TiO₂ slurry nezvimwe zvinowedzera zvichipfuura nemumidziyo ine kumanikidzwa kwakasiyana uye tembiricha, majeli nezvinhu zvinosvibisa zvinogona kuoneka. Kana zvikasadzorwa, zvinokanganisa kunaka kwekunyunguduka uye simba refiber.
Kusefa kwePolymer Yakanyunguduka
Chimwe chezvinhu zvinonyanya kurwadza pakugadzirwa kwepolyester inguva pfupi yekusefa. Mafirita akajairika anovharika nekukurumidza, zvichiita kuti avharwe kakawanda. Kuvharwa kwega kwega kunodhura—kuda kumisa tambo, kudzoreredza fiber, uye kuraswa kwezvinhu zvakabikwa.
Kusefa kwakanaka kwemadziro
Zvigadzirwa
•Mapepa Efirita Akadzama
Zvakagadzirirwa kuoma kusefa zvakanyanya, mafirita aya anoshanda zvakanyanya kune zvinwiwa zvine viscosity yakawanda, zvine huwandu hwakasimba, uye zvakasvibiswa nehutachiona.
•Zvakajairika
Pepa rekusefa rakadzama rine firita yemhando yepamusoro yeAIDS rine kugadzikana kwakanyanya, kushandiswa kwakasiyana-siyana, simba remukati rakakwirira, nyore kushandisa, kutsungirira kwakasimba uye kuchengetedzeka kwakanyanya.
•Mamodule
Mamodule e membrane stack eGreat Wall anogona kunge aine mhando dzakasiyana dzemakadhibhodhi mukati. Kana akabatanidzwa nema membrane stack filters, ari nyore kushandisa, akaparadzaniswa nekunze, uye ane hutsanana uye akachengeteka.
Tekinoroji Yekusefa Kwakanyatsonaka: Tinogadzira mhinduro dzekusefa dzakagadzirirwa maitiro akasiyana kuti tive nechokwadi chekuti tsvina inobviswa uye kuchena kwechigadzirwa.
