I-screw extruder iyithuluzi eliyinhloko lokuguqulwa kokwakhiwa nokuhlanganiswa kwepulasitiki. Enqubweni yangempela yokukhiqiza yokuguqulwa kokuhlanganiswa, i-screw extruder isesimweni sokucindezela okuphezulu kakhulu kanye nesimo sokushisa okuphezulu, futhi ihlushwa ukungqubuzana okukhulu kanye namandla okusika.
Ngenxa yendawo ekhethekile yokusebenza,isikulufu sokukhiphaAkuyona ingxabano evamile phakathi kwensimbi nensimbi, kodwa insimbi ne-polymer, ngakho-ke ukuguguleka kobuso besikulufu kuvame ukuba kubi kakhulu.
Ukuguguleka kwezikulufo kwandisa ibanga phakathi kwesikulufo nomgqomo, okuthinta ukucindezelwa kanye nokunqunywa kwesikulufo ezintweni, ngaleyo ndlela kuholele ekwehleni kwekhwalithi yomkhiqizo. Ngakolunye uhlangothi, ukushintshwa njalo kwesikulufo esigugile akugcini nje ngokwandisa izindleko, kodwa futhi kubambezela ishejuli yokukhiqiza, okuholela ekunciphiseni ukusebenza kahle kokukhiqiza.
Isikulufu ngokuvamile sibangelwa ukuguguleka kwesikhathi eside, isikulufu kanye nokususwa kwebhareli kukhulu kakhulu ekukhishweni nasekukhucululweni okuvamile, kodwa kunezibonelo zomonakalo obangelwa ukwakheka okungafanele noma ukusebenza kahle kokucindezeleka kokusebenza kudlula umkhawulo wamandla. Lokhu okulandelayo kulula ukwethula izizathu zokuguguleka kwesikulufu sokukhucululwa.
1. Izinga lokushisa lokucubungula
Uhlobo ngalunye lwepulasitiki lunezinga lokushisa elifanele lokufaka ipulasitiki, futhi izinga lokushisa lokucubungula imigqomo kufanele lilawulwe eduze kwaleli banga lokushisa. Izinhlayiya zepulasitiki ezivela e-hopper zingene emgqonyeni, zizofika kuqala esigabeni sokudla, esigabeni sokudla kuzovela ukungqubuzana okomile ngokungenakugwenywa, lapho la mapulasitiki engashiswa ngokwanele, ukuncibilika okungalingani, kulula ukubangela ukuguguleka kodonga lwangaphakathi lomgqomo kanye nobuso bezikulufo.
Ngokufanayo, esigabeni sokucindezela kanye nesigaba sokuhlanganiswa, uma isimo sokuncibilika kwepulasitiki singahlelekile futhi singalingani, kuzobangela nokuguga okwandisiwe.
2. Ijubane
Ijubane kufanele lilungiswe kahle. Ngenxa yengxenye yepulasitiki ene-ejenti yokuqinisa, njenge-fiber yengilazi, amaminerali noma ezinye izinto zokugcwalisa. Lezi zinto zivame ukukhuhla izinto zensimbi kakhulu kunepulasitiki encibilikisiwe.
Uma ukusetshenziswa kwesivinini esikhulu, ekuthuthukiseni amandla okusika epulasitiki ngesikhathi esifanayo, kulula ukuthuthukisa ukudabuka kwefayibha, ifayibha edabukile iqukethe ukuphela okubukhali, okwenza amandla okuguga akhule kakhulu. Amaminerali angaphili ebusweni bensimbi ashelela ngesivinini esikhulu; umphumela wawo wokuklwebha awuncane. Ngakho-ke isivinini akufanele silungiswe siphezulu kakhulu.
3. Ukuhlukanisa phakathi kwesikulufu nomgqomo
Isikulufu siyajikeleza emgqonyeni bese ukungqubuzana phakathi kwezinto kanye nendawo yokusebenza yesikulufu bese umgqomo uyaphela kancane kancane, ububanzi besikulufu buyancipha kancane kancane, futhi ububanzi bomgodi wangaphakathi womgqomo buyanda kancane kancane. Ngale ndlela, igebe lobubanzi phakathi kwesikulufu nomgqomo liyakhula ngokuguguleka kancane kancane kwalokhu okubili.
Kodwa-ke, ngenxa yokuthi ukumelana kwekhala kanye nepuleti le-shunt phambi komgqomo akukashintshi, kwandisa ukugeleza kokuvuza kwezinto ezikhishwe lapho zihamba phambili, okungukuthi, futhi izinto zandisa umfutho wokugeleza kusukela egebeni lobubanzi kuya esiqondisweni sokudla. Umphumela uba ukwehla kokukhiqizwa kwemishini yepulasitiki. Lesi simo senza isikhathi sokuhlala kwezinto esilindweni sikhuphuke, okuholela ekuboleni kwezinto. Endabeni ye-PVC, ukubola kwegesi ye-hydrogen chloride kuthuthukisa ukugqwala kwesikulufu nomgqomo.
4. Ukubumba izinto ngokungalingani noma okuxutshwe nezinto zangaphandle zensimbi
Ngenxa yokuthi izinto azihlanganiswanga ngepulasitiki ngokulinganayo, noma kukhona into yangaphandle yensimbi exutshwe nezinto, ukuze amandla e-torque okujikeleza kwezikulufo akhuphuke ngokuzumayo, le torque idlula umkhawulo wamandla wesikulufo, ukuze isikulufo siphuke. Lolu uhlobo lomonakalo ongajwayelekile wengozi.
Lokhu okungenhla yizona zizathu ezivame kakhulu zokuguguleka kwezikulufo; Ngiyethemba ukuthi ngokuqukethwe okungenhla kungakusiza ukuthi ube nokuqonda okwengeziwe kanye nokuqonda isikulufo se-extrusion.
Ukunciphisa ukuguguleka kwezikulufo nokwandisa isikhathi sokuphila kwezikulufo kuzonciphisa kakhulu izindleko zokugcinwa kwemishini, kuqinisekise ikhwalithi yemikhiqizo, futhi kulethe izinzuzo eziphezulu kwezomnotho emabhizinisini.
Okuqukethwe
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.
