Chifukwa chiyani zida zapulasitiki sizingasinthidwe ndi ultrasonically?

Pulasitiki ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri popanga mafakitale amakono.Komabe, chifukwa chapadera katundu, mitundu yosiyanasiyana ya pulasitiki zipangizo zosiyanasiyana kuyenerera kwa akupanga processing.

Choyamba, tiyenera kumvetsa chimene akupanga processing ndi.Akupanga processing amagwiritsa akupanga mphamvu kwaiye ndi mkulu-pafupipafupi kugwedera kunjenjemera zakuthupi mamolekyu padziko workpiece, kupanga izo ofewa ndi oyenda, potero kukwaniritsa cholinga processing.Tekinolojeyi ili ndi ubwino wapamwamba kwambiri, wolondola, wosawononga komanso kuteteza chilengedwe, choncho wakhala akugwiritsidwa ntchito kwambiri popanga mafakitale.

Komabe, zosiyanasiyana nyimbo ndi katundu wa pulasitiki zipangizo zimakhudza awo kuyenerera kwa akupanga processing.Mwachitsanzo, polyethylene (PE) ndi polypropylene (PP), mapulasitiki awiri omwe amagwiritsidwa ntchito kwambiri, ndi abwino kwa akupanga processing.Chifukwa chakuti mamolekyu awo ndi osavuta kumva, palibe magulu odziŵika bwino a mamolekyu olumikizana ndi magulu a mankhwala.Makhalidwe amenewa amalola akupanga mafunde mosavuta kudutsa pulasitiki padziko ndi chifukwa kugwedezeka kwa zinthu mamolekyu, potero kukwaniritsa cholinga processing.

Komabe, zipangizo zina polima monga polyimide (PI), polycarbonate (PC) ndi polyamide (PA) si oyenera akupanga processing.Izi zili choncho chifukwa mamolekyu a zinthuzi ndi ovuta kwambiri, akuwonetsa magulu apamwamba a ma molekyulu ogwirizanitsa ndi magulu a mankhwala a polar.Akupanga mafunde adzalephereka mu zipangizozi, kupanga kukhala kovuta chifukwa kugwedera ndi otaya mamolekyu zakuthupi, kupanga kukhala zosatheka kukwaniritsa processing zolinga.

Komanso, ena apadera mitundu ya zipangizo pulasitiki monga okhwima polyvinyl kolorayidi (PVC) ndi polystyrene (PS) si oyenera akupanga processing.Izi zili choncho chifukwa mamolekyu awo ndi osalimba ndipo sangathe kupirira kugwedezeka kwamphamvu kwamphamvu komwe kumapangidwa ndi mafunde akupanga, omwe angapangitse kuti zinthuzo ziwonongeke kapena kusweka.
Mwachidule, mitundu yosiyanasiyana ya pulasitiki zipangizo zosiyana kusinthika kwa akupanga processing.Posankha njira yoyenera yopangira, mapangidwe ndi katundu wa zinthuzo ziyenera kuganiziridwa kuti zitsimikizidwe kuti ntchitoyo ikukwaniritsidwa bwino.
