6 izinhlobo zepulasitiki ziyafa, uyazazi zonke?

Isikhathi sokufunda esilinganiselwe:Imizuzu emi-4, imizuzwana eyi-8

Ukusetshenziswa kwepulasitiki kuyakhula, futhi nenani lemikhiqizo yepulasitiki liyakhuphuka.Kodwa-ke, ukuklama nokukhiqizwa kwemikhiqizo yepulasitiki kuyinkimbinkimbi kakhulu, futhi ipulasitiki ehlukene iyafa kufanele isetshenziswe ngokusekelwe ezicini zemikhiqizo yepulasitiki ehlukene.Izinsizakalo zokubumba umjovo we-Prolean zinikeza enye indlela eyongayo nethembekile.Onjiniyela bethu banesipiliyoni seminyaka eminingi embonini yokubumba umjovo,xhumana nathi namuhlaukuthola isilinganiso samahhala.

Ipulasitiki yokufaiyithuluzi lokukhiqiza imikhiqizo yepulasitiki.Ekubunjweni komjovo, ifa liyaboshelwa emshinini wokubumba umjovo, ipulasitiki encibilikisiwe ijova emgodini wokubumba futhi ipholiswe futhi imise umgodi, bese kuhlukaniswa ukufa okungaphezulu nokuphansi, bese umkhiqizo ukhishwa emgodini ngokusebenzisa imbobo. i-ejector system bese ishiya idayizi, futhi ekugcineni idayi iyavalwa futhi ngomjovo olandelayo.

Umshini Wokubumba Umjovo, Umthombo ovela ku:wilimedia

Isikhunta sokujova

Kuwuhlobo oluvame kakhulu lwethuluzi lokubumba elisetshenziswa ekukhiqizeni izingxenye ze-thermoplastic.Imishini ehambisanayo yokucubungula yokubumba umjovo umshini wokubumba umjovo.Ipulasitiki iqala ukushiswa futhi inyibilike emgqonyeni oshisayo womshini wokubumba umjovo, bese iphushwa yisikulufa noma i-plunger yomshini wokubumba umjovo, ngomshini wokubumba umjovo womshini kanye nohlelo lokuthulula lwesikhunta emgodini wokubumba, ipulasitiki ipholile futhi iqiniswe, futhi umkhiqizo ukhishwa esikhunjini.Isakhiwo sawo ngokuvamile siquketheizingxenye zokubumba, uhlelo lokuthulula, izingxenye eziqondisayo, indlela yokuphusha, isistimu yokulawula izinga lokushisa, isistimu yokukhipha umoya, izingxenye ezisekelayo nezinye izingxenye, futhi ukukhiqizwa kwenziwa ngensimbi yesikhunta sepulasitiki.Indlela yokucubungula umjovo ngokuvamile isebenza kuphela ekukhiqizeni imikhiqizo yemikhiqizo ye-thermoplastic.

Inkambu yohlelo lokusebenza: imikhiqizo yepulasitiki ekhiqizwa inqubo yokubumba umjovo ibanzi kakhulu, kusukela ezidingweni zansuku zonke kuya kuzo zonke izinhlobo zezinto zikagesi eziyinkimbinkimbi, izingxenye zezimoto, njll. zonke zakhiwe ngokubunjwa komjovo, kuyindlela yokucubungula esetshenziswa kakhulu ekukhiqizeni imikhiqizo yepulasitiki.

Vuthela Isikhunta

Vuthela isikhunta

Izinto ezisetshenziswayo ezihambisana nokubumba i-blow ngokuvamile zibizwa ngokuthi umshini wokubumba i-plastic blow, futhi ukubunjwa kwe-blow kusebenza kuphela ekukhiqizeni izinhlobo zemikhiqizo ye-thermoplastic.

Inkambu yohlelo lokusebenza:njengamabhodlela eziphuzo, imikhiqizo yansuku zonke yamakhemikhali, nezinye izinhlobo zeziqukathi zokupakisha

I-Extrusion Blow

I-extruder yepulasitiki

Imishini yokukhiqiza iyi-extruder yepulasitiki, isimiso sayo esiwukuncibilikisa ipulasitiki eqinile ngaphansi kwezimo zokushisisa nokujikeleza kwesikulufa se-extruder kanye nokucindezela, ukuyifakela ipulasitiki, nokwenza imikhiqizo yepulasitiki eqhubekayo ene-cross-section efana nokuma komlomo. fa ngokusebenzisa ukuma ethize umlomo die.Izinto zayo zokukhiqiza ikakhulukazi zihlanganisa insimbi ye-carbon structural, amathuluzi e-alloy, njll.

Inkambu yohlelo lokusebenza:Uhlobo lwesikhunta esisetshenziselwa ukubumba nokukhiqiza imikhiqizo yepulasitiki emile eqhubekayo, ebizwa nangokuthi inhloko yomshini wokubumba i-extrusion, esetshenziswa kabanzi ekucubunguleni amapayipi, imigoqo, ama-monofilaments, amapuleti, amafilimu, izintambo zocingo kanye nezintambo, amaphrofayili, njll.

I-Blister Mold

I-extrusion yefilimu eshaywayo iyafa

Kuwuhlobo lwesikhunta esisebenzisa ishidi lepulasitiki noma ipuleti njengempahla eluhlaza ukubumba imikhiqizo yepulasitiki elula.Umgomo wawo ukusebenzisa indlela yokwembuleka kwe-vacuum noma indlela yokwenza umoya ocindezelwe ukwenza ipuleti lepulasitiki noma ishidi ligxiliswe kusikhunta se-concave noma isikhunta se-convex, esimweni sokushisa nokuthambisa ukuguqulwa nokunamathisela emgodini wesikhunta ukuze uthole imikhiqizo yokubumba edingekayo.Ingcindezi yesikhunta se-blister iphansi, ngakho-ke izinto zokubumba zenziwe kakhulu nge-aluminium ekhonjiwe noma impahla engeyona eyensimbi, futhi isakhiwo silula.

Inkambu yohlelo lokusebenza:esetshenziswa kakhulu ekukhiqizeni ezinye izidingo zansuku zonke, ukudla, amathoyizi, neminye imikhiqizo yokupakisha.

Isikhunta sokucindezela

Compression Molding Rubber Process

Imishini ye-Compression mold ingumshini wokubumba wokucindezelwa.Indlela yokubumba yokucindezela isekelwe ezicini zepulasitiki, isikhunta sishiswa ekushiseni kokubumba (ngokuvamile ku-103 ° 108 °), bese i-powder yokubumba elinganiselwe ifakwa emgodini wokubumba kanye negumbi lokugcwalisa.Lapho isikhunta sivaliwe, ipulasitiki iyathamba futhi ibe ne-viscous ngaphansi kokushisa okuphezulu nokucindezela, bese yelashwa futhi ifakwe esimweni somkhiqizo oyifunayo ngemva kwesikhathi esithile.

Izinkambu zohlelo lokusebenza: Isikhunta somjovo wokucindezela sisetshenziswa kakhulu ekuhlanganiseni izingxenye zikagesi.Izinto ezisetshenziswa ekwenziweni kwesikhunta sokucindezela ziyafana nalezo ezisetshenziswa ekubunjweni komjovo.

Isikhunta se-polystyrene esinwetshwe kakhulu

Kuyisikhunta esisebenzisa impahla eluhlaza ye-EPS (impahla yobuhlalu eyakhiwe nge-polystyrene ne-ejenti efuthayo) ukubumba izinto zokupakisha zegwebu lezimo ezihlukahlukene ezifunwayo.

Isimiso siwukuthi i-EPS ingabunjwa ngesitimu esibunjeni.Izinto ezisetshenziswa ekwenzeni isikhunta esinjalo ziyi-aluminium ephonsiwe, insimbi engagqwali, ithusi, njll.

Inkambu yohlelo lokusebenza:ikakhulukazi esetshenziselwa ukukhiqiza imikhiqizo yezimboni yokupakisha imikhiqizo.

Ubungcweti namandla ka-Prolean kusiza izinkampani zikhiqize izingxenye ezibunjwe ngomjovo wepulasitiki eziyinkimbinkimbi kakhulu ngokunemba okungajwayelekile.Sinikezela ngezinsizakalo ezithuthukisiwe zokubumba umjovo wepulasitiki njengokubunjwa kwezithombe eziningi kanye nokubunjwa ngokweqile kwemiklamo eyinkimbinkimbi yesikhunta.Vele ulayishe eyakhoAmafayela e-CADfuthi uthole ukucaphuna kwamahhala okusheshayo kanye nokubonisana kumasevisi ahlobene.
