Incazelo yendlela yokubumba umjovo wepulasitiki kanye nenqubo yokukhiqiza isinyathelo ngesinyathelo

Eminyakeni engamashumi amahlanu edlule imboni yezinto zepulasitiki iye yathuthukiswa, ngenani elikhulu, ibusa phezu kwezinto eziyisisekelo, yedlula ngisho nemboni yensimbi. Amapulastiki angenile kuwo wonke amakhaya kungakhathaliseki isimo senhlalo, kuwo wonke amadolobha okuhlanganisa akude kakhulu nasemazweni athuthukile, njengakuwo wonke umnotho. Ukuthuthukiswa kwale mboni kuyamangaza futhi sekuguqule indlela yezwe esiphila kulo.

Inqubo yokubumba umjovo

Izinhlanganisela zepulasitiki zihluke kakhulu komunye nomunye futhi ziboleka ezindleleni ezihlukahlukene zokucubungula. Impahla ngayinye ifaneleka kangcono kwenye yezindlela, nakuba eziningi zingenziwa eziningana zazo. Ezinqubweni eziningi, izinto ezibunjwayo ziyimpushana noma ifomu le-granular, nakuba kwabanye kunomsebenzi wokuqala wokulungisa ngaphambi kokusetshenziswa. Lapho ukushisa kufakwa entweni ye-thermoplastic ukuyincibilikisa, kuthiwa yenziwe ngepulasitiki. Kakade izinto ezincibilikisiwe noma ezishisayo ezenziwe nge-laminated zingenziwa ukuthi zigeleze ngokufaka ingcindezi nokugcwalisa isikhunta lapho impahla iqina futhi ithatha isimo sesikhunta. Le nqubo yaziwa ngokuthi umjovo wokubumba. Umgomo oyisisekelo wokubumba umjovo uhlanganisa le misebenzi emithathu eyisisekelo elandelayo:

1. a) Phakamisa izinga lokushisa lepulasitiki lifike endaweni lapho lingageleza khona ngaphansi kokufakwa kwengcindezi. Lokhu kuvame ukwenziwa ngokufudumeza nokuhlafuna ama-granules aqinile wento ukuze kwakheke ukuncibilika nge-viscosity efanayo kanye nezinga lokushisa. Njengamanje, lokhu kwenziwa ngaphakathi emgqonyeni womshini ngokusebenzisa isikulufu, esihlinzeka ngomsebenzi wemishini (ukungqubuzana) ukuthi kanye nokushisa komgqomo kuncibilike (plasticize) ipulasitiki. Okusho ukuthi, isikulufu sithutha, sixube futhi sifake ipulasitiki izinto zepulasitiki. Lokhu kuboniswa emfanekisweni
2. b) Vumela ukuqina kwento ekubunjweni okuvaliwe. Kulesi sigaba izinto ezincibilikisiwe esezivele zinelayini emgqonyeni womshini zidluliswa (zijovwe) ngokusebenzisa umlomo wombhobho, oxhuma umbhobho eziteshini ezihlukahlukene zesikhunta kuze kube yilapho ufinyelela emigodini lapho uthatha isimo somkhiqizo wokugcina.
3. c) Ukuvula isikhunta ukuze kukhishwe ucezu. Lokhu kwenziwa ngemva kokugcina impahla ngaphansi kwengcindezi ngaphakathi kwesikhunta futhi lapho ukushisa (okwakusetshenziselwa ukwenza ipulasitiki) kukhishwa ukuze kuvunyelwe izinto eziqinile ngendlela oyifunayo.

Ezinqubweni ezihlukahlukene zokubumba, ukuhluka kwezinga lokushisa elincibilikayo noma leplastiki lidlala indima ehlukile kuye ngokuthi i-thermoplastic material noma i-thermofix.

Ukuhlanganiswa kwe- i-thermoplastic izinto zokwakha zenziwa kancane kancane ku-cylinder ye-plasticizing, ngaphansi kwezimo ezilawulwayo. Ukushisa kwangaphandle okunikezwa isilinda se-plasticizing kwengeza ukushisa okukhiqizwa ukungqubuzana kwe-spindle ejikelezayo futhi exuba impahla. Ukulawulwa kwezinga lokushisa ezindaweni ezihlukene zesilinda se-plasticizing kwenziwa ngokusebenzisa ama-thermocouples afakwe ezindaweni ezihlukahlukene endleleni yezinto ezibonakalayo, kusukela ku-hopper kuya ku-nozzle. Ama-thermocouples axhunywe kumathuluzi okulawula okuzenzakalelayo, agcina izinga lokushisa lezoni ngayinye ezingeni elisethiwe. Kodwa-ke, izinga lokushisa langempela lokuncibilika okuzojovwa esikhunjeni lingase lihluke kuleso esirekhodwe ama-thermocouples kungaba kusilinda noma ku-nozzle.

Ngenxa yalesi sizathu, kuyatuseka ukulinganisa ngokuqondile izinga lokushisa lezinto ngokwenza into encane iphume emlonyeni we-insulating plate bese wenza isilinganiso khona lapho. Ukwehluka kwezinga lokushisa esikhunjeni kungakhiqiza izingxenye ezinekhwalithi eguquguqukayo kanye nobukhulu obuhlukahlukene, ukuhlukaniswa ngakunye kwezinga lokushisa elisebenzayo kubangela ukupholisa okusheshayo noma okunensayo kwenqwaba encibilikisiwe ejovwe emgodini wesikhunta. Uma izinga lokushisa lesikhunta lehliswa, ingxenye ebunjiwe iphola ngokushesha futhi lokhu kungakha ukuma okuphawulekayo esakhiweni, ukucindezeleka okukhulu kwangaphakathi, izakhiwo zemishini kanye nokubukeka okungalungile kwendawo.
