Ukubumba kwepulasitiki kuyindlela yobunjiniyela obubandakanya izinqubo ezahlukahlukene zokuguqula ipulasitiki libe yimikhiqizo yepulasitiki. Le ndatshana izokwethula kwinqubo yokubumba yokubumba kokubumba , ukukhishwa, nokushaya ngamandla. Imininingwane imi ngalendlela elandelayo:
Ukubumba komjovo
Ukuhlolisisa umjovo, umgomo ukwengeza izinto zokwengeza ze-granular noma ze-powdery ku-hopper yomshini wokujova, okuqukethwe okuvuthiwe kuyashukunyiswa uguqulwe ku-isikulufa noma ipiston yomshini wokujova, kungena ku-caversity. uhlelo lokuthulula lwe-nozzle kanye nesibumba. , lukhuni futhi lubumba emgodini womuntu. Izici ezithinta ikhwalithi yokubumba komjovo: ingcindezi yomjovo, isikhathi somlingiswa, izinga lokushisa lomjovo.
Inzuzo:
1. Umjikelezo omfishane wokubumba, ukusebenza kahle kokukhiqiza okuphezulu kanye nokuzenzakalela okulula
2, angakha izingxenye zepulasitiki ezinobukhulu obuyinkimbinkimbi, ubukhulu obunembile, kanye nokufakwa kwensimbi noma okungeyona insimbi
3, ikhwalithi yomkhiqizo iqinile
4, uhla olubanzi lokuzivumelanisa nezimo
Okubi:
1, intengo yemishini yokujova iphakeme
2, Isakhiwo Sokwenziwa Komjolo siyinkimbinkimbi
3. Izindleko eziphezulu zokukhiqiza, umjikelezo wokukhiqiza omude, futhi azilungele ukukhiqizwa kwezingxenye zepulasitiki ku-batch eyodwa encane
Isicelo:
Emikhiqizweni yezimboni, imikhiqizo ebunjiwe yokujova ifaka: Izitsha zasekhishini, izindlu zemishini kagesi, amathoyizi nemidlalo, imikhiqizo ehlukahlukene embonini yezimoto, kanye nezingxenye zeminye imikhiqizo eminingi.
Ukukhishwa
I-ExtRONSION: Yaziwa nangokuthi isikhulo sokukhishwa, ikakhulukazi ekubumbeni kwama-thermoplastics, futhi futhi kufanelekile ukwakheka kwe-thermosetting kanye ne-plastitis eqinisiwe nge-fluidity engcono. Inqubo yokubumba isebenzisa isikulufa esijikelezayo ukukhipha impahla efudumele futhi encibilikisiwe ye-thermoplastic kusuka ekhanda lomshini elinesiqalo esiyisiqalo, bese libunjwe yithuluzi elikhudlwana, bese libulwa futhi liqinile futhi liqinile yilobugoli ukuthola isigaba esifunekayo. umkhiqizo.
Inqubo Izici:
1. Izindleko eziphansi zemishini;
2, ukusebenza kulula, inqubo kulula ukuyilawula, futhi kulula ukubona ukukhiqizwa okuzenzakalelayo okuzayo;
3, ukusebenza kahle kokukhiqiza okuphezulu; Ikhwalithi yomkhiqizo iyunifomu futhi icwecwe;
4. Ngokushintsha okufa kwekhanda lomshini, kungakha imikhiqizo noma imikhiqizo eqediwe yezimo ezahlukahlukene zezigaba.
Isicelo:
Emkhakheni wokwakheka komkhiqizo, ukubumba kokukhishwa kwe-Expression kunamandla aqinile. Imikhiqizo ye-ExtRonsion ifaka i-tubing, ifilimu, ibha, i-monofilay, ibhande eliphansi, inetha, isitsha, iwindi, i-monofilament, i-monofilamement kanye namanye amaphrofayili.
Ukushaya ukubumba
Ukubumba okushayayo: Izinto ezibunjiwe ze-thermoplastic ezibunjiwe ezikhishwe ku-extwiched zifakwe isikhunta, bese kuthi umoya ushaywa ungena ezintweni eziluhlaza, futhi impahla ebiwe ekhanyayo yandiswa yingcindezi yomoya ukuze iboshelwe ebusweni bodonga lwe-capity yohlobo, futhi ekugcineni sehlile. Indlela yokuphulukisa kwisimo somkhiqizo oyifunayo. Ukubumba okushaya kuhlukaniswe ngezinhlobo ezimbili: ukushaya ifilimu nokuqhuma okuyize:
Ukushaya ifilimu:
Ukubumba amafilimu okubumba ukuveza ipulasitiki elibunjiwe kusuka kushubhu elithambile eliyindilinga e-ancuper ye-extrar die, ngenkathi kushaya umoya ocindezelwe emgodini wangaphakathi we-tube emfishane . Ifilimu enkulu ye-tubular ethathwa ngemuva kokupholisa.
Ukubumba Okushayiwe kwe-Hollow:
Ukubumba okukhohlakala okuyisisekelo kuyindlela yesibili yokubumba lapho i-parison efana nerabha evaliwe kwi-cavetha yokubumba ikhuphuke emkhiqizweni ongenalutho ngokusebenzisa umfutho wegesi, futhi kuyindlela yokukhiqiza umkhiqizo wepulasitiki ongenalutho. Ukubumba okuqhakaza okuyize kunezindlela ezahlukahlukene zokukhiqiza zamaphayiphu, njengokuqhakaza kwe-extrusion ukubumba, ukushelela kokushisa okubumba, futhi ukwelula ukubumba okushayayo.
1) Ukuqhakaza kwe-Extrusion Ukubumba: Ukuqunjelwa kokuqhakaza kokuqalisa ukukhipha i-tubular parison nge-extuder, i-sandwid
2) Ukuqunjelwa kokushibilika: I-parison esetshenzisiwe yatholakala ngokubumba komjovo. I-parison ishiywe kwi-mandrel yesikhunta, futhi ngemuva kokuba isikhunta sivaliwe yi-blow isikhunta, umoya ocindezelwe wethulwa kusuka ekubumbeni okuyisisekelo ukwengeza i-parison, nangemva kokuphola, umkhiqizo utholakele ngemuva kokuduma.
3) Yelula ukubumba okuvuthayo: I-parison eshiyelwe emazingeni okushisa we-Breating ibekwa ekubumbeni okuvuthayo, elunwe lonke ngenduku yokwelula, futhi yelule kakhulu futhi ifakwe umoya ocindezelwe ukuze uthole umkhiqizo. indlela.
Inzuzo:
Umkhiqizo unobukhulu bodonga olufanayo, ukubekezelela isisindo okuncane, ukucubungula okuncane okuthunyelwe kanye nokona okuncane kwemfucuza; Ilungele ukukhiqiza imikhiqizo emihle emincane ngosayizi omkhulu we-batch.
Isicelo:
Ukuqhuma kwamafilimu kusetshenziselwa ikakhulukazi ukwenza isikhunta esincanyana seplasitiki; Ukubumba okuqhakaza okungekho okusetshenziselwa ikakhulukazi ukwenza imikhiqizo yepulasitiki engenalutho.
