Chiyambi chaPolyesterKusefa kwa Ulusi
Ulusi wa polyester ndi umodzi mwa ulusi wofunika kwambiri padziko lonse lapansi, womwe umapanga maziko a mafakitale kuyambira mafashoni mpaka nsalu zamafakitale. Mphamvu yake, kulimba kwake, komanso kugwiritsa ntchito bwino ndalama zake zimapangitsa kuti ikhale chisankho chabwino kwambiri pa nsalu, mipando, makapeti, komanso ntchito zaukadaulo. Komabe, kupeza ulusi wa polyester wapamwamba kwambiri sikophweka. Imafuna kuwongolera kolondola pagawo lililonse lopanga, ndipo chinthu chimodzi chomwe nthawi zambiri chimanyalanyazidwa koma chofunikira kwambiri ndi ichikusefa.
Kusefa kumagwira ntchito ngati choteteza cha ulusi wabwino. Kuyambira kukonzekera zopangira mpaka kutulutsa kwa polima wosungunuka, zinthu zodetsa zimatha kulowa nthawi iliyonse. Ngakhale zinthu zodetsa zazing'ono kwambiri zimakhala ndi mphamvu yowononga magwiridwe antchito a ulusi, zomwe zimapangitsa kuti mphamvu yolimba ikhale yofooka, utoto wosafanana, kapena kuyimitsa kupanga kokwera mtengo chifukwa cha kusweka kwa spin. Zomera zamakono za ulusi sizingakwanitse kukwanitsa izi, ndichifukwa chake kusefa kwapamwamba kwakhala njira yabwino kwambiri.kufunikira kwa njira.
Chifukwa Chake Kusefa Ndikofunikira muPolyesterKupanga Ulusi
Kuti mumvetse chifukwa chake kusefa kuli kofunika kwambiri, ganizirani za kupanga polyester ngati unyolo. Chingwe chilichonse—chopangira zinthu zopangira, esterification, polymerization, spinning—chiyenera kukhala cholimba kuti unyolo ukhale wodalirika. Chingwe chimodzi chofooka, monga kuipitsidwa kwa zinthu zopangira kapena ma gel mu polymer yosungunuka, chingasokoneze njira yonse.
Kusefa kumatsimikizira:
•Kusasinthasintha- ulusi uli ndi mphamvu yofanana, kapangidwe kake, komanso umatenga utoto mofanana.
•Kudalirika- kuchepetsa nthawi yopuma komanso nthawi yochepa yopuma.
•Kuchita bwino- nthawi yayitali yogwiritsira ntchito fyuluta komanso kuchepetsa kukonza.
•Phindu- ntchito zoyeretsa zimachepetsa zinyalala ndi ndalama zomwe zimagwiritsidwa ntchito.
Mwachidule, kusefa sikutanthauza kungochotsa tinthu tating'onoting'ono; koma ndi nkhani yakukonza bwino ntchito yonse yopangidwachilengedwechifukwa cha ubwino ndi magwiridwe antchito.
KumvetsetsaPolyesterKupanga Ulusi
Kupanga ulusi wa polyester kumaphatikizapo magawo angapo ogwirizana:
1. YaiwisiKukonzekera Zinthu:Terephthalic acid (TPA) kapena dimethyl terephthalate (DMT) imaphatikizidwa ndi ethylene glycol (EG).
2. Kuyezetsa magazi/Kusintha kwa ma ester:Kuchitapo kanthu kwa mankhwala kumapanga ester yapakati.
3. Kuchuluka kwa madzi m'thupi:Maunyolo aatali a polima amapanga polyethylene terephthalate (PET).
4. Kusungunula Kuzungulira:PET yosungunuka imatulutsidwa kudzera mu spinnerets kukhala ulusi.
5. Kujambula ndi Kukongoletsa:Ulusi umatambasulidwa ndi kupangidwa kuti ukwaniritse zomwe mukufuna.
Pa gawo lililonse, zinthu zodetsa—kaya fumbi, ma gels, kapena zotsalira za catalyst—zingathe kuwononga magwiridwe antchito. Mwachitsanzo, ma agglomerates mu zowonjezera za TiO₂ amatha kuletsa ma spinnerets, kapena ma gels omwe ali mu kusungunuka amatha kufooketsa mphamvu ya ulusi. Kusefa kumaletsa zoopsa izi, kusunga mzere wopanga bwino komanso kutulutsa kwake kumakhala kokwera mtengo nthawi zonse.
YaiwisiKusefa Zinthu: Kumanga Maziko Olimba
Gawo loyamba pakutsimikizira kuti ulusi ndi wabwino ndikusefa zinthu zopangira monga TPA, EG, zowonjezera za catalysts (Sb₂O₃), ndi TiO₂. Ngati sizikusefedwa, izi zimayambitsa tinthu tating'onoting'ono ndi ma agglomerations omwe amayambitsa mavuto pambuyo pake: zosefera za polima zotsekeka, nthawi yochepa yozungulira, ndi ulusi wofooka.
Kusefa Panthawi Yoyezera
Kuyezera ndi gawo lovuta kwambiri pomwe zinthu zodetsa nthawi zambiri zimakhalapo. Pamene TiO₂ slurry ndi zowonjezera zina zimadutsa m'mitsempha yokhala ndi kupsinjika ndi kutentha kosiyanasiyana, ma gels ndi zinthu zodetsa zolimba zimatha kuwoneka. Ngati siziyang'aniridwa, zimawononga ubwino wa kusungunuka ndi mphamvu ya ulusi.
Kusefera kwa Polima Yosungunuka
Chimodzi mwa zinthu zovuta kwambiri popanga polyester ndi nthawi yochepa yogwiritsira ntchito zosefera. Zosefera zachizolowezi zimatsekeka mwachangu, zomwe zimapangitsa kuti zitsekedwe pafupipafupi. Kutseka kulikonse kumakhala kokwera mtengo—kumafuna kuyimitsa kwa mzere, kutsekereza ulusi, komanso kuwononga zinthu zopangira.
