Izindaba

I-Sharkskin (i-melt fracture) ithinta ikhwalithi ye-polymer extrusion nokusebenza kahle. Funda izimbangela zayo, izixazululo zendabuko, nokuthi kungani izinsiza zokucubungula i-fluorine ne-PFAS-free polymer njenge-SILIKE SILIMER Polymer Processing Aids kungenye indlela eqhubekayo.

Iyini i-sharkskin noma i-surface melt fracture ngesikhathi sokukhishwa kwama-polymers?

I-Sharkskin (ephinde yaziwe ngokuthi i-surface melt fracture) iphutha elibonakalayo ngesikhathi kukhishwa i-polymer encibilikayo, lapho i-extrudate iba nokubukeka okumaholoholo, okumagagasi, noma okunyakazayo okufana nokuthungwa kwesikhumba sikashaka. ikakhulukazi ezinqubweni ezifana nokuvunguza kwefilimu, ukubunjwa kwe-extrusion, nokunamathela ngocingo.

Ibonakala ngokuthi:

Indawo emangelengele, e-matte, noma egobile ku-extrudate (i-polymer iyancibilika njengoba iphuma kufa).

Ngandlela-thile ibukeka njengesikhumba sikashaka, okuyilapho igama livela khona.

Izimbangela ze-sharkskin ku-polymer extrusion

I-Sharkskin iwuhlobo lokuqhekeka kwencibilika, okubangelwa ukuntengantenga kwesixhumi esibonakalayo sodonga lwe-polymer-die. Lapho i-polymer encibilika iphuma ekufeni, ithola ukwehla okungazelelwe kwengcindezi kanye nokwanda okukhulu kwesivinini.

Uma ukuncibilika kunamathela ngokuqinile odongeni lokufa (ukucindezeleka okuphezulu kwe-shear odongeni), ungqimba olungaphezulu lunwetshwa kakhulu.Lokhu kuholela ekuqhumeni ngezikhathi ezithile nokuklebhuka kwe-polymer melt surface, okwenza iphethini ye-sharkskin.

Izimo Ezijwayelekile ze-Sharkskin

Ingcindezi ye-shear ngaphezu komkhawulo obalulekile (ngokuvamile ~ 0.1–0.3 MPa, kuye nge-polymer).

Isivinini esikhulu sokukhipha/ishear.

I-high-viscosity noma ama-polymers anesisindo esiphezulu se-molecular asengozini kakhulu, avela kaningi ku-PP nama-polymers aqondile (isb, i-LLDPE,mLLDPE) kunakuma-polymers anegatsha.

Imiphumela Yabakhiqizi

Izinga eliphezulu eliphansi lamafilimu, amashidi, noma okokunamathela.

Izakhiwo ezincishisiwe zemishini (ngoba amaphutha angaba izigxili zokucindezeleka).

Izinkinga ngokucaca okubonakalayo kanye nobuhle.

Ungawaxazulula kanjani ama-Sharkskin kanye nokuqhekeka kwama-polymer melt extrudates?

Traditional Polymer Additives Solutions & Limitations

Ama-PPA e-Fluoropolymer asetshenziswe kusukela ngeminyaka yawo-1960 ukunciphisa isikhumba sikashaka. Basebenza ngokuthuthela endaweni efayo ngesikhathi sokukhipha, behlisa amandla angaphezulu kanye nokwenza lula ukushelela kwe-polymer. Nakuba esebenza kahle, lawa ma-PPA asekelwe ku-PFAS, aphakamisa ukukhathazeka kwemvelo nempilo:

• Ukuphikelela emhlabathini nasemanzini

• Ukuqongelela kwezinto eziphilayo kanye nokuphazamiseka okungenzeka kwe-endocrine

• Ukuhlolwa kokulawula emhlabeni wonke

Ukunyuka Kwezinsiza Zokucubungula I-Polymer Engenayo I-PFAS: Ikusasa Lezixazululo Eziqhubekayo Ze-Extrusion

I-SILIKE SILIMER PFAS-Free PPA Solutions for Smarter, Greener Extrusion

Uchungechunge lwe-SILIMER luhlanganisa uhla oluphelele lweIzinsiza zokucubungula ze-polymer zamahhala ze-PFAS (ama-PPAs) yakhelwe izidingo zesimanje zokukhiqiza:

• 100% izithasiselo zamahhala ze-PFAS

•Ama-masterbatches angenayo i-fluorine

• Ama-PPA ahlanzekile angenayo i-fluorine

• Izithasiselo zamahhala ze-PTFE

Lezi zixazululo zenzelwe ukukhulisa ukusebenza kahle kokucubungula ngenkathi kuqedwa ubungozi obuhlobene ne-PFAS.

 Ama-PPA angenawo ama-SILIKE SILIMER PFAS ahambisana nezinhlobonhlobo zama-polymers kanye nezinqubo ze-extrusion, athuthukisa ukucubungula ku:

• Ama-Polyolefin namareyini e-polyolefin agaywe kabusha

• Amafilimu aphephuliwe, alingisi, nawezendlalelo eziningi

• I-Fiber ne-monofilament extrusion

•Ikhebula nepayipi extrusion

•I-Masterbatch kanye nezicelo ezihlanganisayo

Kungakhathaliseki ukuthi ikhiqiza amafilimu, amapayipi, izintambo, noma amafayibha, ama-SILIMER PPA asiza abakhiqizi ukuba bathole ukucubungula okushelelayo, izindawo ezingcono, kanye nokusebenza okuthuthukisiwe.

Uyazi ukuthi iyiphi i-PPA yamahhala ye-PFAS ekhethwa ngabakhiqizi be-polymer?
