Izindaba

I-Metallocene polyethylene(mPE) uhlobo lwe-resin ye-polyethylene eyenziwe ngesisekelo sama-catalysts e-metallocene, okuwubuchwepheshe obusha obubaluleke kakhulu embonini ye-polyolefin eminyakeni yamuva nje. Izinhlobo zemikhiqizo zifaka phakathi i-metallocene low density high pressure polyethylene, i-metallocene high density low pressure polyethylene kanye ne-metallocene linear low density polyethylene. I-Metallocene polyethylene isetshenziswe kabanzi enqubweni yokubumba i-co-extrusion blow ngenxa yezakhiwo zayo eziyingqayizivele zomzimba kanye nokusebenza kwayo kokucubungula, futhi ithandwa kakhulu ngamabhizinisi okupakisha nokuphrinta asekhaya nakwamanye amazwe.

Izakhiwo ze-polyethylene ye-metallocene

1. I-polyethylene ye-Metallocene inobude obungcono ngesikhathi sokuphuka kune-polyethylene evamile. I-polyethylene ye-Metallocene inamandla angcono okuthinta ngenxa yesisindo sayo sama-molecule aphezulu kanye nokusabalala kwayo okujiyile kune-polyethylene evamile.

2. Izinga lokushisa eliphansi lokuvala ukushisa kanye namandla aphezulu okuvala ukushisa.

3. Ukucaca okungcono kanye nenani eliphansi lomswakama.

Izicelo zefilimu ye-polyethylene ye-Metallocene

1. Ukupakishwa kokudla

Ifilimu ye-polyethylene ye-Metallocene ingafakwa i-laminate nge-BOPET, i-BOPP, i-BOPA namanye amafilimu, afaneleka kakhulu ekupakisheni ukudla kwenyama, ukudla okulula, ukudla okuqandisiwe neminye imikhiqizo.

2. Ukupakishwa kwemikhiqizo yezolimo

Ifilimu ye-polyethylene ye-metallocene ebunjiwe eyenziwe ngezinqubo ezahlukene zokuvimbela umhwamuko wamanzi inhle, kuyilapho ukungena komoya-mpilo kuphezulu, lesi sici siyenza ifaneleke kakhulu ekupakishweni kwezithelo nemifino emisha. Ngaphezu kwalokho, ifilimu ye-polyethylene ebhujiswe yi-metallocene inezici zamandla aphezulu, ukulwa nokugqwala, ukulwa nokuconsa, ukumelana nokuguga kanye nokubonakala okuhle.

3. Izikhwama ezisindayo

Izikhwama ezisindayo zisetshenziswa kakhulu ekupakisheni izinto zokusetshenziswa zepulasitiki, umanyolo, ukudla, ilayisi kanye nokusanhlamvu. Ukuvela kwe-metallocene polyethylene, izikhwama ezisindayo kungenza ukusebenza kokuvala, ukumelana nomswakama, ukusebenza okungangeni manzi, ukusebenza kokulwa nokuguga kube ngcono kakhulu, uma amazinga okushisa aphezulu engawuthambisi ukuguquguquka, umkhuhlane awuphuli izinzuzo zokuqhekeka.

Ukwengezwa kwama-metallocenes ekucutshungulweni kwefilimu kuthuthukisa amandla okuthamba kanye nekhwalithi yefilimu, kodwa futhi kunezinselele ezithile ekucutshungulweni, njengokuthamba okuphezulu kwama-metallocenes okuthinta ukugeleza kokucubungula kanye nesimo sokuphuka kokuncibilika komkhiqizo enqubweni yokukhipha.

Izizathu zokuqhekeka kwe-metallocene polyethylene encibilikisiwe ekucutshungulweni kwefilimu zingafaka okulandelayo:

1. ukujiya okuphezulu: i-metallocene polyethylene ine-viscosity ephezulu yokuncibilika, okungaholela ekuqhekekeni kokuncibilika ngesikhathi sokukhipha njengoba ukuncibilika kufakwa emandleni aphezulu okucheba njengoba kudlula ku-orifice die.

2. Ukulawulwa kwezinga lokushisa okunganele: Uma izinga lokushisa lenqubo liphezulu kakhulu noma lingalingani, lokhu kungabangela ukuthi izinto zincibilike kakhulu kwezinye izindawo kuyilapho zihlala ziqinile kwezinye, futhi lesi simo sokuncibilika okungalingani singaholela ekuqhekekeni kobuso bokuncibilika.

3. Ukucindezeleka okuncishisiwe: Enqubweni yokukhipha, ukuncibilika kungase kube nokucindezeleka okukhulu kokucheba e-muzzle die, ikakhulukazi uma i-muzzle die ingaklanywanga kahle noma isivinini sokucubungula sishesha kakhulu, lokhu kucindezeleka okuphezulu kokucheba kungaholela ekuqhekekeni kokuncibilika.

4. Izithasiselo noma ama-masterbatches: Izithasiselo noma ama-masterbatches angeziwe ngesikhathi sokucubungula angahlakazeki ngokulinganayo angathinta nezici zokugeleza kokuncibilika, okuholela ekuqhekekeni kokuncibilika.

I-SILIKE PFAS-free PPA SILIMER 9300，Ukuphuka okuncibilikisiwe kwe-metallocene polyethylene

Imikhiqizo yochungechunge lwe-SILIMER iyizinsiza zokucubungula i-polymer ezingenayo i-PFAS (PPAS)ezacwaningwa futhi zathuthukiswa yiChengdu Silike. Lolu chungechunge lwemikhiqizo luyi-Pure modified Copolysiloxane, enezakhiwo ze-polysiloxane kanye nomphumela we-polar weqembu eliguquliwe.

I-SILIMER-9300iyisengezo se-silicone esiqukethe amaqembu asebenzayo e-polar, esisetshenziswa ku-PE, PP kanye neminye imikhiqizo yepulasitiki nerabha, singathuthukisa kakhulu ukucubungula nokukhulula, sinciphise ukwakheka kwe-die futhi sithuthukise izinkinga zokuqhekeka kokuncibilika, ukuze ukunciphisa umkhiqizo kube ngcono.

Ngesikhathi esifanayo,I-SILIMER 9300inesakhiwo esikhethekile, ihambisana kahle ne-matrix resin, ayinamvula, ayinawo umthelela ekubukekeni komkhiqizo kanye nokwelashwa kwendawo. Kunconywa ukuthi ixutshwe ibe yi-masterbatch ethile yokuqukethwe kuqala, bese isetshenziswa kuma-polymer e-polyolefin, ukuyifaka ngokulinganisela kungaba yimpumelelo enkulu.

EngezaI-SILIMER 9300Uma kucatshangelwa inqubo, ukugeleza kokuncibilika, ukucutshungulwa, kanye nokugcotshwa kwe-resin kungathuthuka ngempumelelo kanye nokuqeda ukuqhekeka kokuncibilika, ukumelana okukhulu kokuguguleka, i-coefficient encane yokungqubuzana, ukwandisa umjikelezo wokuhlanza imishini, ukunciphisa isikhathi sokungasebenzi, kanye nokukhishwa okuphezulu kanye nobuso bemikhiqizo obungcono, ukukhetha okuphelele kokufaka esikhundleni se-PPA emsulwa esekelwe ku-fluorine.
