Kodi mumadziwa bwanji za pulasitiki?

Kodi mumadziwa bwanji za pulasitiki? Kuyamba kwa njira zochizira pulasitiki wamba.

Nkhani yomaliza idayambitsa njira zinayi zopangira mapulasitiki, ndipo lero tipitiliza kuwafotokozera. Chonde nditsatireni ndikuwerenga limodzi.

(5) Kuwomba Kuwomba.

Kuwomba ndi njira yopangira zinthu zapulasitiki zopanda kanthu. Imagwiritsa ntchito mphamvu ya mpweya kuti iphulike chotsekedwa mu nkhungu kukhala chinthu chopanda kanthu.

(6) Kalendala.

Calender ndiye gawo lomaliza pakumaliza kwa zikopa zolemera. Zimagwiritsa ntchito pulasitiki ya ulusi pansi pa kusakaniza kutentha kuti igulitse pamwamba pa nsalu yathyathyathya kapena kutulutsa mizere yofanana yozungulira kuti ikhale yonyezimira. Zinthuzo zikadyetsedwa, zimatenthedwa ndikusungunuka, kenako zimapangidwa kukhala mapepala kapena zingwe, zomwe zimakhazikika ndikukulungidwa. Zomwe zimagwiritsidwa ntchito kwambiri ndi polyvinyl chloride.

(7) Kugwa.

Pansi pa zochita za njira zitatu m'goli compressive kupsyinjika, akusowekapo ndi extruded ku dzenje kapena kusiyana nkhungu kuchepetsa m'dera mtanda ndi kuonjezera kutalika, ndi kukhala processing njira ya chofunika mankhwala otchedwa extrusion. Kukonzekera kwa billet kumatchedwa pultrusion.

(8) Kupanga Vacuum.

Kupanga vacuum nthawi zambiri kumatchedwa blister. Mfundo yaikulu ndi yakuti pepala la pulasitiki lathyathyathya limatenthedwa ndi kufewetsa, kenako limalowetsedwa ndi vacuum pamwamba pa nkhungu, ndikupanga pambuyo pozizira. Amagwiritsidwa ntchito kwambiri muzowunikira zamapulasitiki zamapulasitiki, zokongoletsera zotsatsa ndi mafakitale ena.

(9) Kumangirira Kozungulira.

Kupanga mpukutu kumadziwikanso kuti kuponyera kozungulira. Zinthu zapulasitiki zimawonjezeredwa ku nkhungu, zomwe zimatenthedwa pozizungulira pa nkhwangwa ziwiri zowongoka. Mwa njira imeneyi, zinthu pulasitiki mu nkhungu pang'onopang'ono ndi uniformly amamatira padziko lonse nkhungu patsekeke pansi zochita za mphamvu yokoka ndi kutentha mphamvu. Ndiye, akamaumba kwa mawonekedwe chofunika, ndiyeno pambuyo yozizira kutsirizitsa demoulding, potsiriza kupeza mankhwala.

Pamwambapa ndi zili zonse za pulasitiki processing luso, chonde pitirizani kulabadira.
