Thermoforming mankhwala amapangidwa pamaziko a mapepala, amene anamaliza ndi extruder. Pulasitiki ndi kuumbidwa mu yunifolomu kusungunula ndi dongosolo extrusion, ndi njira imeneyi kuthamanga anamanga ndi wononga mosalekeza extruder mutu.

Ngati mapasa-screw extruder agawidwa m'magulu awiri ofunikira a "extrusion" ndi "transmission", ndiye "extrusion part" ndi gawo lofunikira la "kuwonetsetsa khalidwe", ndipo "gawo lotumizira" ndilo gawo lofunikira la "kupititsa patsogolo ntchito" ndi "kuonetsetsa kuti khalidwe labwino".

Colour Masterbatch, yomwe imadziwikanso kuti colorants, ndi mtundu watsopano wamitundu yapadera yopangira zinthu za polima, yomwe imadziwikanso kuti kukonzekera kwa pigment.

Chiyambireni kutulukira kwa mapasa-screw extruder, wakhala akugwiritsidwa ntchito kwambiri m'munda wa kusinthidwa pulasitiki, ndipo ndi zida pachimake m'munda wa kusinthidwa. Fakitale iliyonse yosinthira imasamalira bwino ma twin-screw extruder, koma pantchito ya tsiku ndi tsiku, ndizosapeweka ...

Zida zopangidwa ndi matabwa ndi pulasitiki zofupikitsidwa monga WPC zimapangidwa ndi ulusi wochepa kwambiri monga utuchi, tchipisi tamatabwa, nsungwi, mankhusu ampunga, mphodza, zipolopolo za chiponde, udzu wa thonje, ndi zina zotero. Amasakanizidwa ndi gawo lina lazinthu zoyambira pulasitiki pogwiritsa ntchito mfundo za chemistry ya polima komanso mawonekedwe a kudzaza pulasitiki ndikusintha. Pambuyo pokonza mwapadera, amasinthidwa ndikupangidwa kukhala chinthu chofunikira chosinthika komanso chosinthika chokhala ndi zinthu zambiri komanso mawonekedwe osiyanasiyana. Zida za WPC zili ndi mawonekedwe asanu:

Pulasitiki extruder ndi wamba pulasitiki makina ndi zipangizo. Pa ntchito ya tsiku ndi tsiku extruder, zolakwa zosiyanasiyana zikhoza kuchitika mu extruder, amene amakhudza yachibadwa kupanga makina pulasitiki. Zotsatirazi ndizomwe zimayambitsa ndi njira zothetsera extrude ...

The meshing co rotating twin screw extruder yomwe timagwiritsa ntchito popanga ili ndi magawo asanu ndi limodzi ofunika: kutentha pamwamba, kuthamanga kwambiri, kutayika kwa viscosity, kusakaniza index.
