Sharkskin (melt fracture) cuam tshuam rau polymer extrusion zoo thiab efficiency. Kawm txog nws cov laj thawj, cov kev daws teeb meem ib txwm muaj, thiab vim li cas fluorine thiab PFAS-dawb polymer ua cov khoom siv xws li SILIKE SILIMER Polymer Processing Aids yog lwm txoj hauv kev.

Dab tsi yog sharkskin lossis nto yaj tawg thaum lub sij hawm extrusion ntawm polymers?

Sharkskin (tseem hu ua deg melt fracture) yog qhov tsis xws luag nyob rau hauv lub sij hawm extrusion ntawm polymer melts, qhov twg cov extrudate tsim ib tug ntxhib, wavy, los yog rippled tsos zoo li cov kev ntxhib los mos ntawm shark daim tawv nqaij. tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem xws li zaj duab xis tshuab, extrusion molding, thiab hlau txheej.

Nws yog characterized los ntawm:

Ib qho ntxhib, matte, lossis ridged nto ntawm lub extrudate (lub polymer yaj thaum nws tawm hauv qhov tuag).

Nws zoo li me ntsis zoo li kev ntxhib los mos ntawm daim tawv nqaij shark, uas yog lub npe los ntawm.

Ua rau sharkskin nyob rau hauv polymer extrusion

Sharkskin yog ib daim ntawv ntawm cov pob txha tawg, tshwm sim los ntawm kev tsis sib haum xeeb ntawm cov phab ntsa polymer-tuag. Thaum cov polymer yaj tawm ntawm qhov tuag, nws muaj kev poob siab tam sim ntawd thiab qhov nrawm nrawm.

Yog hais tias cov yaj nplaum nplaum nplaum nplaum rau ntawm phab ntsa tuag (siab phab ntsa shear stress), txheej txheej saum npoo tau ncab ntau dhau.Qhov no ua rau lub sijhawm tawg thiab tawg ntawm cov polymer yaj nto, uas tsim cov qauv sharkskin.

Cov xwm txheej zoo rau Sharkskin

Shear kev ntxhov siab tshaj qhov txwv tsis pub tshaj (feem ntau ~ 0.1-0.3 MPa, nyob ntawm cov polymer).

High extrusion ceev / shear tus nqi.

High-viscosity los yog high-molecular-weight polymers yog cov raug mob, tshwm sim ntau zaus hauv PP thiab linear polymers (xws li, LLDPE,mLLDPE) dua li ntawm cov ceg ntoo polymers.

Kev rau txim rau cov neeg tsim khoom

Tsis zoo ntawm cov yeeb yaj kiab, cov ntawv, lossis cov txheej txheem tsis zoo.

Txo cov khoom siv hluav taws xob (vim qhov tsis xws luag tuaj yeem ua rau muaj kev ntxhov siab).

Teeb meem nrog optical clarity thiab zoo nkauj.

Yuav daws Sharkskin thiab tawg ntawm polymer yaj extrudates li cas?

Tsoos Polymer Additives Solutions & Limitations

Fluoropolymer PPAs tau siv txij li xyoo 1960 los txo cov tawv nqaij tawv. Lawv ua haujlwm los ntawm kev tsiv mus rau qhov chaw tuag thaum lub sij hawm extrusion, txo qis zog saum npoo thiab ua kom yooj yim rau cov ntaub ntawv polymer. Thaum ua tau zoo, PPAs no yog PFAS-raws li, ua rau muaj kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv:

• Kev nyob ruaj hauv av thiab dej

• Bioaccumululation thiab tej zaum yuav cuam tshuam endocrine

• Kev soj ntsuam xyuas thoob ntiaj teb
