Sharkskin (narkewar karaya) yana rinjayar ingancin extrusion polymer da inganci. Koyi abubuwan sa, mafita na al'ada, kuma me yasa fluorine da kayan aikin sarrafa polymer kyauta na PFAS kamar SILIKE SILIMER Polymer Processing Aids sune mafita mai dorewa.

Mene ne sharkskin ko surface narke karaya a lokacin extrusion na polymers?

Sharkskin (wanda kuma aka sani da karayar narkewar saman) wani lahani ne na saman da ake gani a lokacin extrusion na polymer narke, inda extrudate ya haifar da m, mai kauri, ko tsage-tsalle mai kama da nau'in fata shark. musamman a cikin matakai kamar busa fim, gyare-gyaren extrusion, da murfin waya.

Yana da siffa da:

M, matte, ko ridged surface a kan extrudate (polymer narke yayin da ya fita da mutu).

Yana kama da nau'in fata shark, wanda shine inda sunan ya fito.

Abubuwan da ke haifar da sharkskin a cikin extrusion polymer

Sharkskin wani nau'i ne na narke karaya, wanda ya haifar da rashin kwanciyar hankali a bangon bangon polymer-die. Lokacin da polymer narke ya fita daga mutuwa, yana samun raguwar matsa lamba da yawa da kuma karuwa mai yawa a cikin sauri.

Idan narke ya tsaya da ƙarfi ga bangon mutu (haɓaka girman girman bango), layin saman yana buɗewa da yawa. Wannan yana haifar da fashewar lokaci-lokaci da yayyage saman narke polymer, wanda ke haifar da ƙirar sharkskin.
