Chidziwitso Chokwanira cha Wotsegulira

Pokonza ndikugwiritsa ntchito mafilimu apulasitiki, kupititsa patsogolo katundu wa utomoni kapena zinthu zina zamafilimu sizikukwaniritsa zofunikira zaukadaulo wawo wopangira, ndikofunikira kuwonjezera zowonjezera zapulasitiki zomwe zingasinthe mawonekedwe awo kuti asinthe magwiridwe antchito amtunduwu. mankhwala. Monga chimodzi mwazofunikira zowonjezera filimu yowombedwa, m'munsimu muli tsatanetsatane wa pulasitiki wothandizira. Pali atatu omwe amagwiritsidwa ntchito poterera poterera anti-blocking agents: oleic amide, erucamide, silicon dioxide; Kuphatikiza pazowonjezera, pali ma masterbatches ogwira ntchito monga ma masterbatches otseguka ndi ma masterbatches osalala.

1.Woterera
Kuonjezera chosakaniza chosalala kuti filimuyi ikhale ngati kuwonjezera madzi pakati pa zidutswa ziwiri za galasi, kupanga filimu yapulasitiki yosavuta kusuntha zigawo ziwirizo koma zovuta kuzilekanitsa.

2.Kutsegula pakamwa
Kuwonjezera chotsegulira kapena masterbatch ku filimuyo monga kugwiritsa ntchito sandpaper kuti ikhale pamwamba pakati pa zidutswa ziwiri za galasi, kuti zikhale zosavuta kupatutsa zigawo ziwiri za filimuyo, koma zimakhala zovuta kusuntha.

3.Open masterbatch
Zomwe zimapangidwa ndi silika (inorganic)

4.Smooth masterbatch
Zosakaniza: amides (organic). Onjezani amide ndi anti-blocking agent ku masterbatch kuti mupange 20 ~ 30%.

5.Kusankha kwa wotsegulira
Mu masterbatch yosalala yotseguka, kusankha kwa amide ndi silika ndikofunikira kwambiri. Ubwino wa amide ndi wosagwirizana, zomwe zimapangitsa kuti pakhale mphamvu ya masterbatch pa nembanemba nthawi ndi nthawi, monga kukoma kwakukulu, mawanga akuda ndi zina zotero, zomwe zimayambitsidwa ndi zonyansa zambiri komanso zonyansa zamafuta a nyama. Posankha, ziyenera kutsimikiziridwa molingana ndi kuyesa kwa ntchito ndi kugwiritsa ntchito amide. Kusankhidwa kwa silika ndikofunika kwambiri, ndipo kuyenera kuganiziridwa kuchokera kuzinthu zambiri monga kukula kwa tinthu, malo enieni, madzi, chithandizo chapamwamba, ndi zina zotero, zomwe zimakhudza kwambiri kupanga masterbatch ndi ndondomeko yotulutsa filimu.
