Ukubonakala okuphezulu kwe-PP umugqa we-extrusion weshidi isetshenziswa kakhulu ukukhiqiza ishidi lokubona okuphezulu le-polypropylene (PP). Ngenxa yokubonakala kwayo okuhle, ukumelana namakhemikhali, ukuqina kanye nokuphindeka kwayo, isetshenziswa kabanzi ekupakisheni ukudla, ekupakisheni izimpahla zezokwelapha, ekuvikelweni kwemikhiqizo kagesi, ezindaweni zokunyathelisa nakwezinye izinkambu.
Okulandelayo umbono jikelele wezingxenye eziyisisekelo kanye nomsebenzi womugqa wokukhiqiza:
Ukulungiselela impahla eluhlaza
Okokuqala, sebenzisa izinhlayiya ze-PP resin ezomile njengezinto zokusetshenziswa. Lezi zinto zokusetshenziswa zidinga ukwelashwa okuqinile kokomisa ukuze kususwe umswakama futhi kugwenywe amabhamuza ngesikhathi sokucubungula, okuzothinta ukucaca kanye nekhwalithi yeshidi.
Umkhiphi
Izinto ezixubile zifakwa ku-extruder enezikulufo ezimbili noma ezinezikulufo ezimbili ngohlelo lokudla. i-extruder incibilikisa izinto ezihlanganisiwe zibe ukuncibilika okufanayo ngokushisa kanye nesigaba sokusika, isigaba sokwenza ipulasitiki, kanye nesigaba sokuhambisa sesikulufu.
Uhlelo lokuhlunga
Ukuze kuqinisekiswe ukucaca kanye nobumsulwa beshidi, ukuncibilika kuzodlula esihlungini esinembile ngemva kokukhipha ukuze kususwe ukungcola okungenzeka, njengezinhlayiya ze-resin ezingancibilikisiwe noma izinto zangaphandle.
Iphampu yemitha
Ukuncibilika okuhlungiwe kungena empompini yokulinganisa. Ngokulawula ngokunembile izinga lokugeleza kokuncibilika nokusebenza kanye nomshini oyinhloko, izinto ezincibilikisiwe zingalethwa ngempumelelo nangokuzinzile kudayi okwakha ishidi, kudlala indima ebalulekile ekulungiseni ukujiya kweshidi.
Isikhunta bese ufe
Ngemva kokuba izinto ze-PP ezincibilikisiwe ziphume ku-extruder, zidlula ku-mold eklanyelwe ngokukhethekile bese zifa ukuze zakhe isimo seshidi elinobukhulu obudingekayo kanye nokuba yisicaba, futhi zilawule ububanzi bomkhiqizo. Kumashidi abonakala kakhulu, ukwakheka kwe-mold kanye ne-die kubaluleke kakhulu, okuqinisekisa ukuthi izinto zigeleza ngokulinganayo futhi akukho mabhamuza akhiqizwayo ukuze kufezwe izidingo eziphezulu zokubonakala.
Uhlelo lokupholisa nokwakha
Ishidi elishisayo elincibilikayo eliphuma ekhanda le-die lidlula esikhumbeni noma ku-die bese lingena ngokushesha ku-calendar ukuze liphole ngokushesha futhi libumbeke ukuze kulungiswe ukujiya nobubanzi be-die. ishidi lokukhiphaIkhalenda ilawula izinga lokushisa le-roller ukuze ipholise amanzi ngombhoshongo wamanzi (noma i-chiller). Njengoba i-PP inokuncipha okukhulu, kumele ipholiswe ngokuphelele ngaphambi kokugoqa ukuze kuqedwe ukucindezeleka kwangaphakathi, ukuze umkhiqizo ukwazi ukufinyelela izinga futhi unganciphi ngemva kokushiywa isikhathi esithile ngemva kokugoqa.
Idivayisi yokudonsa nokusika
Ngemva kokupholisa nokubumba, ishidi lidlula kudivayisi yokusika bese lisikwa ngokosayizi odingekayo. Ububanzi obudingekayo beshidi buyalungiswa bese imiphetho engafaneleki ezinhlangothini zombili iyasikwa. Idivayisi yokudonsa kanye nekhalenda kuxhunywe ngokuvumelana, okungalawula ngempumelelo ukukhiqizwa kweshidi, kulawule isivinini salo kanye nokucindezeleka, futhi kugcine ukufana kwesicaba nokujiya kweshidi.
Isistimu yokuphefumula
Ekugcineni, amashidi asikiwe afakwa esilingini. I-reel ilawulwa yi-servo motor enokucindezeleka okuqhubekayo, okungaqinisekisa ukuhlanzeka kwemiphetho yama-coil. Ukucindezeleka okugoqekayo kwama-coil angaphakathi nangaphandle kuyafana, ngakho-ke ama-coil ngeke aqine ngaphakathi futhi akhululeke ngaphandle, okuyinto elula ukupakisha, ukugcina kanye nokuthuthwa okulandelayo.
Uma ufuna ukwenza ukusika, ukugoqa, ukuphrinta kanye nokupakisha, udinga ukwengeza isilayidi ekugcineni. Enqubweni yokukhiqiza, udinga futhi ukwengeza idivayisi yokulayina ukuze ulayine izinhlangothi ezingaphezulu nezingezansi zeshidi ngaphambi kokulisika (ifilimu ingasikwa ngesandla) ukuvikela ishidi ngesikhathi sokuthuthwa ngaphandle kokulimaza ubuso beshidi.
Kuyo yonke inqubo yokukhiqiza, ukulawulwa kwezinga lokushisa, isilinganiso sezinto ezibonakalayo, ukusebenza kahle kokupholisa kanye nokunemba komshini yizinto ezibalulekile ezithinta ikhwalithi Amashidi e-PP abonisa ukukhanya okuphezuluNgaphezu kwalokho, ukuze kuhlangatshezwane nezidingo ezahlukene zohlelo lokusebenza, umugqa wokukhiqiza ungahlanganiswa nesistimu yokondla eyengeziwe ukuze kufakwe ama-antistatic agents, amafutha okugcoba noma ezinye iziguquli ukuze kuthuthukiswe ukusebenza kweshidi.
Njengoba eseneminyaka ecishe ibe ngu-20 embonini yemishini yokukhipha izinto ezihlakaniphile, ubelokhu ephethe izindima ezibalulekile eJwell Machinery, okuhlanganisa noMphathi Jikelele kanye noSihlalo Ojikelezayo. Kusukela ngo-2024, uphathe izinkampani eziningi ezingaphansi kwakhe, eqhuba ukwanda kwebhizinisi kanye nokuthuthukiswa kwezimboni, ngenkathi ehola ukusungula izinto ezintsha ekukhiqizeni izinto ezihlakaniphile kanye nokukhula komhlaba wonke.
