Ukuphotha, okubuye kwaziwe ngokuthi yi-chemical fibre forming, ukukhiqizwa kwemicu yamakhemikhali. Yenziwe ngezinhlanganisela ezithile ze-polymer ibe isixazululo se-colloidal noma incibilike ibe yincibilika yi-spinneret ecindezelwe ngaphandle kwezimbobo ezinhle ukwenza inqubo yemicu yamakhemikhali. Kunezinhlobo ezimbili eziyinhloko zezindlela zokucubungula: ukuphotha kwesixazululo kanye nokuphotha okuncibilika. Kule nqubo, kungase kuphakame izinkinga zokucubungula ezilandelayo:

Ukugeleza kokuncibilika okungazinzile:Ngenxa yokuthi ukugeleza kokuncibilika kuthinteka yizinto eziningi, ezifana ne-melt viscosity, izinga lokushisa, izinga lokugeleza, njll. ezinye izinkinga.

Ukwelula i-fiber engalingani: Ukwelula kuyisinyathelo esibalulekile enqubweni yokuphotha, engakhuphula amandla okuqina kanye ne-tensile modulus yefiber. Kodwa-ke, uma ukunwetshwa kungafani, kuzoholela kububanzi be-fiber engalingani ngisho nokuphuka.

Izinga eliphezulu lokukhubazeka:Enqubweni yokuphotha, ngenxa yobunkimbinkimbi bokuncibilika kanye nokushintsha kwezimo zokucutshungulwa, amaphutha, kanye nemikhiqizo enesici kuvame ukukhiqizwa, njengama-burrs, amakristalu, amabhamuza, njll. Lokhu kulimala nemikhiqizo enesici kuzothinta ukubukeka nokusebenza umkhiqizo, futhi wehlise izinga lomkhiqizo kanye nesivuno.

Ikhwalithi ye-fiber surface engalungile:ikhwalithi ye-fiber surface iyisici esibalulekile esithinta izakhiwo ze-fiber, ezithinta ngokuqondile ukunamathela kanye nomsebenzi ongaphezulu wemicu nezinye izinto. Enqubweni yokuphotha, uma izinga le-fiber surface liphansi, kuzoholela ekwehleni kokusebenza kwefayibha futhi kuthinte ngisho nempilo yesevisi yomkhiqizo.

Ngakho-ke, ohlelweni lokuphotha, kuyadingeka ukuxazulula izinkinga zokucubungula ezingenhla ngokuqhubeka nokwandisa izimo zokucubungula, ukuthuthukisa ukugeleza kwenqubo, ukulawula ikhwalithi, ukwengeza usizo lokucubungula, njll., ukuthuthukisa ikhwalithi nokusebenza kahle kokukhiqiza komkhiqizo. .

I-SILIKE Fluorine-Free PPA: Ukuthuthukisa Ukusebenza Kahle, Ukusimama, kanye Nokuphepha Emisebenzini Yokuphotha >>

SILIKE uchungechunge lwe-PPA olungenayo i-fluorideimikhiqizo ngokupheleleizinsiza zokucubungula ze-PPA ezingena-fluorideithuthukiswe yi-SILIKE, enezinhlobonhlobo zezinhlelo zokusebenza, ezingangena esikhundleni ngokuphelele izinsiza zokucubungula ze-PPA fluoridation, njengesithambiso enqubweni yokuphotha futhi ingadlala indima enhle kakhulu:

Ukuthambisa okuthuthukisiwe: I-SILIKE Fluorine-Free PPA SILIMER 5090inciphisa i-viscosity yokuncibilika futhi ithuthukise ukugeleza kokuncibilika. Lokhu kunomthelela ekukhipheni okubushelelezi kwe-polymer encibilikisiwe emishini yokuphotha futhi kuqinisekisa ukwakheka okufanayo kwefayibha.

Ukuqedwa kokuqhekeka kokuncibilika:Ukwengezwa kweI-SILIKE Fluorine-Free PPA SILIMER 5090inciphisa i-coefficient of friction, inciphisa i-torque, ithuthukise ukuthambisa kwangaphakathi nangaphandle, iqede ngempumelelo ukuphuka kwe-ncibilika, futhi inwebe impilo yesevisi ye-fiber.

Ikhwalithi yendawo ethuthukisiwe: I-SILIKE Fluorine-Free PPA SILIMER 5090ithuthukisa ngempumelelo indawo engaphezulu ye-fiber futhi inciphise ukucindezeleka kwangaphakathi kanye nezinsalela ezincibilikayo, okuholela ekubeni indawo yefayibha ebushelelezi enama-burrs namabala ambalwa.

Ukusetshenziswa kwamandla okuncishisiwe: NgobaSILIKE i-PPA engena-fluorineinganciphisa i-viscosity encibilikayo kanye nokumelana nokungqubuzana, inganciphisa noma iqede ukushona kwekhanda lomshini, yandise isikhathi sokukhiqiza esiqhubekayo, inciphise ukusetshenziswa kwamandla ngesikhathi sokukhipha amandla, futhi ngaleyo ndlela inciphise izindleko zokukhiqiza.

Sekukonke,SILIKE i-PPA masterbatch engenafluorineidlala indima enqubweni yokuphotha ngokuthuthukisa ukuncibilika kwe-ncibilika, ukuqeda ukuphuka kwe-ncibilika, ukunweba imijikelezo yokuhlanza imishini, ukuthuthukisa ikhwalithi ephezulu, kanye nokuthuthukisa ukusebenza kahle kokukhiqiza, ngaleyo ndlela kuthuthukisa inqubo yokuphotha kanye nokwenza ngcono izinga lemicu ekhiqizwayo.

I-SILIKE Fluorine-Free PPAinohlelo olubanzi lwezinhlelo zokusebenza, hhayi nje nge-Spinning kuphela kodwa nezintambo nezintambo, amafilimu, ama-masterbatches, amakhemikhali e-petrochemicals, i-metallocene polypropylene(mPP), i-metallocene polyethylene(mPE), nokunye. Kodwa-ke, izinhlelo zokusebenza ezithile zidinga ukulungiswa futhi zenziwe ngcono ngokuya ngezinto ezahlukahlukene kanye nezidingo zokukhiqiza. Uma unemibuzo nganoma yisiphi isicelo esingenhla, i-SILIKE ijabule kakhulu ukwamukela umbuzo wakho, futhi simagange ukuhlola ezinye izindawo zokufaka isicelo.I-PFAS-free polymer processing aids (PPA)nawe.
