1. Isihluzo kunye nombhobho odibeneyo
Ukungcola kweplastiki kunokususwa ngesihluzo sombhobho owandisiweyo, oko kukuthi, ukunyibilika kunye neplastiki ihamba ngomjelo, ohlukaniswe kwindawo encinci ngokufaka.Ezi zicucu kunye nezikhewu zinokususa ukungcola kwaye ziphucule ukuxutywa kweeplastiki.Ke ngoko, umxube omiselweyo unokusetyenziselwa ukufikelela kwisiphumo esingcono sokuxuba.Ezi zixhobo zinokufakwa phakathi kwe-cylinder ye-injection kunye ne-injection nozzle yokwahlula kunye nokuxuba iglue etyhidiweyo.Uninzi lwazo lwenza ukunyibilika kuhambe kumjelo wensimbi engenasici.
2. Ukudinwa
Ezinye iiplastiki kufuneka zifakwe umoya kumbhobho wokutofa ngexesha lokutofa ukuze irhasi ibaleke.Kwiimeko ezininzi, ezi gesi zingumoya kuphela, kodwa zinokuba ngamanzi okanye i-molekyuli enye yeegesi ezikhutshwe ngokunyibilika.Ukuba ezi gesi azikwazi ukukhutshwa, ziya kunyanzeliswa yi-glue enyibilikayo kwaye zifakwe kwi-mold, eya kwanda kwaye yenze ama-bubbles kwimveliso.Ukukhupha irhasi ngaphambi kokuba ifike kwi-nozzle okanye kwi-mold, nciphisa okanye unciphise i-diameter ye-screw root ukuze ucinezele ukunyibilika kwi-cylinder ye-injection.
Apha, irhasi inokukhutshwa kwimingxuma okanye imingxuma kwi-injection cylinder.Emva koko, ububanzi bengcambu ye-screw buyanda, kwaye i-glue enyibilikayo ene-volatiles isusiwe isetyenziswe kwi-nozzle.Oomatshini bokubumba ngesitofu abaxhotyiswe ngesi sixhobo babizwa ngokuba ngoomatshini bokubumba inaliti yokukhupha.Ngaphezulu komatshini wokubumba inaliti yokukhupha, kufuneka kubekho isitshisi esinamandla kunye nesixhobo sokukhupha umsi esilungileyo sokususa iigesi ezinokuba yingozi.
3. Khangela ivalve
Kungakhathaliseki ukuba luhlobo luni lwe-screw olusetyenzisiweyo, inqaku layo lihlala lixhotyiswe ngevalve yokumisa.Ukuze uthintele iplastiki ukuba ingaphumi kumbhobho, isixhobo sokunciphisa uxinzelelo (intambo ebuyela umva) okanye umbhobho okhethekileyo uya kufakwa.Kwimeko yokusebenzisa i-anti-abortion supply kunye nokuthengisa, kufuneka ihlolwe rhoqo, kuba yinxalenye ebalulekileyo ye-cylinder yokudubula.Okwangoku, i-nozzle yohlobo lokutshintsha ayisetyenziswanga ngokubanzi, kuba kulula ukuvuza iplastiki kunye nokubola kwisixhobo.Okwangoku, uhlobo ngalunye lweplastiki lunoluhlu lweentlobo ezifanelekileyo zemibhobho yokudubula.
4. Isantya sokujikeleza se-screw
Isantya sokujikeleza se-screw sichaphazela kakhulu ukuzinza kwenkqubo yokubumba inaliti kunye nobushushu obusebenza kwiplastiki.Okukhona i-screw ijikeleza ngokukhawuleza, iqondo lokushisa liphezulu.Xa i-screw ijikeleza ngesantya esiphezulu, i-friction (shear) amandla adluliselwe kwiplastiki iphucula ukusebenza kakuhle kweplastiki, kodwa kwandisa ukungalingani kweqondo lokushisa elinyibilikayo.Ngenxa yokubaluleka kwesantya somphezulu we-screw, isantya sokujikeleza somatshini omkhulu wokubumba wenaliti kufuneka sibe ngaphantsi kwalowo womatshini wokubumba owenziwe ngenaliti encinci, kuba ubushushu be-chear obuveliswa sisikrufu esikhulu buphezulu kakhulu kunolo lomatshini wokubumba. isikrufu esincinci kwisantya esifanayo sokujikeleza.Ngenxa yeeplastiki ezahlukeneyo, isantya sokujikeleza isikhonkwane sikwahlukile.
5. Uqikelelo lwamandla okwenza iplastiki
Ukugqiba ukuba umgangatho wemveliso unokugcinwa kuyo yonke inkqubo yokuvelisa, ifomyula elula ehambelana nemveliso kunye nomthamo weplastiki ingasetyenziswa ngolu hlobo lulandelayo: T = (iitoliti iyonke yokuvuthela gx3600) ÷ (isixa seplastiki sokubumba umatshini wokubumba kg / hx1000 ) t lixesha elincinane lomjikelo.Ukuba ixesha lomjikelo lokungunda lingaphantsi kwe-t, umatshini wokubumba inaliti awukwazi ukwenza iplastiki ngokupheleleyo ukufezekisa i-viscosity efanayo yokunyibilika, ngoko ke iindawo zokubumba inaliti zihlala zineenxa.Ngokukodwa, xa isitofu sibumba iimveliso ezinodonga olucekeceke okanye oluchanekileyo, isixa sokutofa kunye nesixa seplastiki kufuneka sihambelane.
6. Bala ixesha lokugcinwa kunye nokubaluleka
Njengesiqhelo, ixesha lokuhlala leplastiki ethile kumatshini othile wokubumba inaliti kufuneka ibalwe.Ngokukodwa xa umatshini omkhulu wokubumba wenaliti usebenzisa inani elincinci lokutofa, iplastiki kulula ukubola, engabonakali ngokuqwalasela.Ukuba ixesha lokugcinwa lifutshane, iplastiki ayiyi kuba yiplastiki ngokufanayo;Ipropathi yeplastiki iya kubola ngokunyuka kwexesha lokugcinwa.
Ngoko ke, ixesha lokugcinwa kufuneka ligcinwe lifana.Iindlela: ukuqinisekisa ukuba igalelo leplastiki kumatshini wokubumba umjovo unokwakheka okuzinzile, ubungakanani obuhambelanayo kunye nokuma.Ukuba kukho nakuphi na ukungaqhelekanga okanye ilahleko kwiindawo zomatshini wokubumba inaliti, xela kwisebe lolondolozo.
7. Ubushushu bomngundo
Ngalo lonke ixesha khangela ukuba umatshini wokubumba unaliti usetwe kwaye uyasebenza kubushushu obuchazwe kwiphepha lerekhodi.Oku kubaluleke kakhulu.Kuba iqondo lobushushu liya kuchaphazela ukugqiba komphezulu kunye nesivuno seendawo ezibunjiweyo zenaliti.Onke amaxabiso alinganisiweyo kufuneka abhalwe kwaye umatshini wokubumba inaliti uhlolwe ngexesha elichaziweyo.
