Ngenkqubela phambili eqhubekayo yetekhnoloji yemveliso yelaphu, ngakumbi nangakumbi iintsinga ezintsha ziye zaba yimathiriyeli ekrwada yamalaphu.Namhlanje, ndiza kukwazisa ikakhulu kwitekhnoloji yokuchonga yefiber yepolyester esetyenzisiweyo.
Kuyaqondwa ukuba kwixesha elidlulileyo, ngenxa yokungabikho kweendlela zokuhlola kunye nokungakwazi kwee-arhente zokuvavanya ukukhupha iingxelo ezisemgangathweni, amashishini awakwazi ukunandipha imigaqo-nkqubo yesizwe echaphazelekayo, kwaye kwangaxeshanye kubangele ukudideka ekubhalweni kwezinye iimveliso zepolyester.
Yintoni i-polyester (PET) fiber?
Oko kukuthi, inkunkuma ye-polyester (i-PET) ye-polymer kunye nenkunkuma ye-polyester (i-PET) yempahla ye-textile iphinda isetyenziswe kwaye iqhutywe kwi-polyethylene terephthalate fiber.
Ngokwabantu abaqhelekileyo, i-polyester fiber esetyenzisiweyo (eyaziwa apha njenge-polyester esetyenzisiweyo) ibhekiselele kwipolyester esetyenzisiweyo (efana neeflakes zebhotile, ugwebu, inkunkuma yesilika, i-pulp yenkunkuma, inkunkuma yamalaphu, njl.njl.) eyenziwe ngeenkqubo zokurisayikilishwa.I-Ester fiber.
Umgaqo wokuchongwa
Ngokusekelwe kumahluko obalulekileyo phakathi kwenkqubo yokucubungula i-polyester esetyenzisiweyo kunye ne-polyester enyulu, ekhokelela kwiimpawu ezahlukeneyo, isampuli iqhutywe ngokwemiqathango echaziweyo kwaye ivavanywe kwi-chromatograph yolwelo oluphezulu.Ngokomahluko kwincopho yendawo yesampulu phantsi kwamaxesha ahlukeneyo okugcinwa , Ukufezekisa injongo yokuchongwa komgangatho.
Inyathelo lokuchonga
1. IMethanolysis
2. Ukudumba-Ukutsalwa
3. Ukusebenza okuphezulu kwechromatography yolwelo
Ulwelo lonyango olusetyenzwe apha ngasentla kwe-1 kunye ne-2 ngokulandelelanayo luxhomekeke ekusebenzeni okuphezulu kolwelo lwekromatografi.
4. Ukusetyenzwa kwedatha kunye nokuchongwa
I-polyester esetyenzisiweyo iya kubangela utshintsho kumxholo kunye nokuhanjiswa kwe-macromolecular heterogeneous chain links kunye ne-oligomers ngexesha lenkqubo yokulungiselela, enokusetyenziswa njengesiseko sokuchongwa kwe-polyester ehlaziyiweyo kunye ne-virgin polyester.
Incopho yendawo ethile kunye nolwazi oluyincopho yophawu lubonisiwe kwitheyibhile engezantsi.

Khangela kwikamva
Ngokunyuka kokusetyenziswa kwe-polyester kunye nokuqonda kwabantu ngokukhuselwa kwendalo, ingqwalasela engakumbi ihlawulwa ekuhlaziyweni kwenkunkuma ye-polyester.Ukusetyenziswa kwenkunkuma yepolyester ukuvelisa ifayibha yepolyester esetyenzisiweyo kunokunciphisa iindleko, ukunciphisa ukusetyenziswa kweoli, kunye nokuphucula izibonelelo zoqoqosho, ezibaluleke kakhulu kuphuhliso oluzinzileyo lweshishini lemichiza yefiber.
Kwangaxeshanye, ngokunyuka kwenani le-polyester esetyenzisiweyo, umba wokutshintshwa kwe-polyester esetyenzisiweyo kunye ne-virgin polyester uye watsala ingqalelo ngakumbi nangakumbi kwishishini.Ixabiso lentengo yezi zimbini likwabonisa ulungelelwaniso oluthile olulungileyo, kwaye ukufumanisa umahluko phakathi kwezi zimbini iTekhnoloji ifumana ingqalelo ngakumbi nangakumbi.
