Pulasitiki extrusion process ndi njira yowongoka yomwe imaphatikizapo kusungunula mikanda ya utomoni (yaiwisi ya thermostat), kuyisefa ndikuyipanga kukhala mawonekedwe operekedwa.Chophimba chozungulira chimathandizira kukankhira pansi mbiya yotenthedwa mpaka kutentha komwe kumaperekedwa.Pulasitiki wosungunula amadutsa m'chiboliboli kuti apatse chinthu chomaliza mawonekedwe ake.Kusefa kumapereka mankhwala omaliza ndi kusinthasintha kofanana.Pano pali kulongosola kwachangu kwa ndondomeko yonse.

Gawo 1:

Njirayi imayamba ndikubweretsa zinthu zapulasitiki zosaphika monga ma granules ndi ma pellets mu hopper ndikudyetsa mu extruder.Zojambulajambula kapena zowonjezera zimawonjezedwa ngati zopangira zilibe.Sirafu yozungulira imathandizira kuyenda kwa utomoni waiwisi kudzera muchipinda chotenthetsera cha cylindrical.

Zopangira za hopper zimadutsa pa mmero wa chakudya kupita ku sikona yokulirapo mkati mwa mbiya yopingasa.

Gawo 3:

Zida zosiyanasiyana zimakhala ndi katundu wosiyana, kuphatikizapo kutentha kosungunuka.Pamene utomoni waiwisi umadutsa m'chipinda chotentha, umatenthedwa ndi kutentha kwake komwe kumasungunuka, kuyambira 400 mpaka 530 madigiri Fahrenheit.Utoto umasakanizidwa bwino ndi nthawi yomwe imafika kumapeto kwa screw.

Utoto usanadutse mufa kuti upange mawonekedwe a chinthu chomaliza, umadutsa pazenera lolimbikitsidwa ndi mbale yosweka.Chophimbacho chimachotsa zowonongeka kapena zosagwirizana zomwe zingakhale mu pulasitiki yosungunuka.Utotowu tsopano wakonzeka kufa chifukwa umalowetsedwa m'bowo kuti uzizizira komanso kuumitsa.Kusamba m'madzi kapena zoziziritsa kuziziritsa zimathandizira kuziziritsa.

Gawo 5:

Njira yotulutsira mbiri ya pulasitiki iyenera kukhala m'njira yoti utomoni umayenda bwino komanso molingana m'magawo angapo.Ubwino wa mankhwala omaliza umadalira kugwirizana kwa ndondomeko yonse.

Zida Zopangira Zopangira Pulasitiki Extrusion
Zopangira pulasitiki zosiyanasiyana zimatha kutenthedwa ndikupangidwa kukhala mbiri yopitilira.Makampani amagwiritsa ntchito zipangizo zosiyanasiyana, kuphatikizapo polycarbonate, PVC, zipangizo zobwezerezedwanso, nayiloni ndi polypropylene (PP).
