1. Ukuhlolisisa
Imitjhini yokwenza i-vacuum ziinsetjenziswa eziqakathekileko zokukhiqiza ezisetjenziselwa ukwenza iingcenye zeplastiki. Imitjhini le isetjenziswa khulu eembonini ezihlukahlukeneko.
2. Umthetho Wokusebenza
Emqoka, imitjhini yokwakha nge-vacuum ye-pvc isebenza ngokufuthumeza iphepha lepulasitiki eliphaphathekileko bekube kulapho sele lithambile. Iphepha leplastiki libekwa phezu kwesikhunta nofana ifomu, bese kusetjenziswa i-vacuum ukudonsa umoya phakathi kwephepha nesikhunta. Lokhu kwenza bona iplastiki ivumelane nejamo lesikhunta, okwenza bona kube nomkhiqizo opheleleko.
2.1 Ukusebenzisa izinto ezihlukahlukeneko kanye neenzuzo
Enye yeenzuzo eziqakathekileko imitjhini yokwenza i-vacuum ezenzakalelako yindlela abasebenza ngayo ngeendlela ezinengi. Zingasetjenziswa ngezinto ezinengi zeplastiki, okufaka hlangana i-high-impact polystyrene (HIPS), ama-acrylic, kanye ne-polyethylene terephthalate (PET). Phezu kwalokho, zingasetjenziselwa ukwenza iingcenye namalunga wobukhulu obuhlukahlukeneko, kusukela eencenyeni ezincani neziyinkimbinkimbi ukuya ezakhiweni ezinkulu, eziyinkimbinkimbi.
Okhunye okuhle kwemitjhini emikhulu yokwenza i-vacuum yindleko yayo ephasi begodu kulula ukuyisebenzisa. Nayiqathaniswa neminye imihlobo yemitjhini yokukhiqiza, imitjhini yokwenza i-vacuum ivamise ukuthengeka begodu itlhoga ukubandulwa okuncani nobungcweti ukobana isebenze kuhle. Lokhu kwenza bona babe yindlela ekhangako emabhizinisini amancani namabhizinisi aqalako afuna ukukhiqiza iingcenye zeplastiki ngaphakathi.
2.2 Ubudisi nokutjhuguluka
Imitjhini yokwakha isitja ingenza amajamo ahlangahlangeneko nemiklamo engaba budisi nofana engeze yenzeka ngezinye iindlela zokukhiqiza. Ngokutjhisa iphepha leplastiki begodu usebenzise i-vacuum ukuyibumba phezu kwesikhunta nofana ifomu, umtjhini ungakha iingcenye ezinemininingwana ehlukileko namakhontu.
Ukwenza iingcenye ezisezingeni eliphezulu, kuqakathekile ukusebenzisa ukuhlanganiswa kwemisho emide nemifitjhani, kanye nezakhiwo zemisho ezihlukahlukeneko nokukhetha kwamagama. Indlela le yenza ummongo onamandla nothakazelisako odosa amehlo womfundi begodu unikela ilwazi eliqakathekileko.
3. Isiphetho
Ekuphetheni, imitjhini yokwenza i-blister vacuum yingcenye eqakathekileko yokukhiqiza kwesimanjemanje. Ngokusebenzisa iinkambisolawulo zokutjhisa ne-vacuum, imitjhini le ingenza amalunga weplastiki namalunga wobukhulu obuhlukahlukeneko nobudisi. Ukusetjenziswa kwazo, ukubhadela, nokusetjenziswa lula kwenza bona zibe yindlela ehle khulu emabhizinisini wawo woke amasayizi, begodu ukusetjenziswa kwazo akunamkhawulo.
