Okokuqala, khetha isixhobo sokufudumeza esichanekileyo
Ukususa iplastiki egxininiswe kwisikrufu ngomlilo okanye ukuqhotsa yeyona ndlela iqhelekileyo nesebenzayo kwiiyunithi zokusetyenzwa kweplastiki, kodwa ilangatye le-acetylene akufuneki lisetyenziswe ukucoca isikrufu.
Indlela echanekileyo nesebenzayo: sebenzisa i-blowtorch ngokukhawuleza emva kokuba isikrufu sisetyenziselwa ukucoca.Ngenxa yokuba i-screw inobushushu ngexesha lokucubungula, ukuhanjiswa kobushushu be-screw kusafana.
Okwesibini, khetha i-arhente yokucoca efanelekileyo
Kukho iintlobo ezininzi zezicoci ze-screw (izinto zokucoca izikrufu) kwimarike, uninzi lwazo zibiza kakhulu kwaye zineziphumo ezahlukeneyo.Iinkampani zokulungisa iplastiki zinokusebenzisa iirasi ezahlukeneyo ukwenza izinto zokucoca izikrufu ngokweemeko zazo zokuvelisa.
Okwesithathu, khetha indlela yokucoca echanekileyo
Isinyathelo sokuqala sokucoca i-screw kukucima ukufaka ukutya, oko kukuthi, ukuvala i-port yokutya ephantsi kwe-hopper;Emva koko unciphise isantya se-screw ukuya kwi-15-25r / min kwaye ugcine esi santya kude kube yi-melted flow phambi kwe-die stop flowing.Ubushushu bazo zonke iindawo zokufudumeza zombhobho kufuneka zibekwe kwi-200 ° C.Ngokukhawuleza ukuba umgqomo ufikelele kulo bushushu, ukucoca kuqala.
Ngokuxhomekeke kwinkqubo ye-extrusion (ukufa kunokufuneka kususwe ukunciphisa umngcipheko woxinzelelo olugqithisileyo ekupheleni kwe-extruder), ukucocwa kufuneka kwenziwe ngumntu omnye: umqhubi ubona isantya se-screw kunye ne-torque kwipaneli yokulawula, ngelixa uqwalasela uxinzelelo lwe-extrusion ukuqinisekisa ukuba uxinzelelo lwenkqubo aluphezulu kakhulu.Ngethuba lenkqubo yonke, isantya se-screw kufuneka sigcinwe ngaphakathi kwe-20r / min.Kwizicelo ezinoxinzelelo oluphantsi uyafa, musa ukususa ukufa kokucoca kwindawo yokuqala.Xa i-extrusion iguqulwa ngokupheleleyo kwi-resin yokucoca ukuya kwi-resin yokucoca, ukufa kumisiwe kwaye kususwe, kwaye i-screw iphinda iqaliswe (ngaphakathi kwe-10r / min) ukuvumela ukuba i-resin yokucoca intsalela iphume.
Okwesine, khetha izixhobo ezifanelekileyo zokucoca
Izixhobo ezifanelekileyo kunye nezinto zokucoca kufuneka zibandakanye: iiglavu ezikwazi ukumelana nobushushu, iiglavu, i-copper scrapers, iibrashi zobhedu, i-copper wire mesh, i-stearic acid, i-drills yombane, i-barrel rula, i-cotton cloth.
Nje ukuba i-resin yokucoca iyeke ukuphuma, isikrufu sinokurhoxiswa kwisixhobo.Kwizikrufu ezinenkqubo yokupholisa, susa umgca wombhobho kunye noqhagamshelo lwe-swivel phambi kokuba uqalise isixhobo sokukrazula isikrufu, esinokudityaniswa kwibhokisi yegiya.Sebenzisa isixhobo sokukrazula isikrufu ukutyhala isikrufu ngaphambili, siveze indawo yezikrufu ezi-4-5 zokucoca.
I-resin yokucoca kwi-screw inokucocwa nge-scraper yobhedu kunye ne-brush yobhedu.Emva kokuba i-resin yokucoca kwi-screw eveziweyo ihlanjululwe, isixhobo siya kutyhalelwa phambili i-4-5 screws usebenzisa i-screw extraction device kwaye uqhubeke nokucoca.Oku kwaphinda kwaphindwa kwaye ekugqibeleni uninzi lwesikrufu satyhalelwa ngaphandle komphanda.
Emva kokuba ininzi ye-resin yokucoca isusiwe, fafaza i-stearic acid kwi-screw;Emva koko sebenzisa i-mesh yocingo lobhedu ukususa intsalela eseleyo, kwaye emva kokuba isikrufu sonke sigudiswe yi-mesh yocingo lobhedu, sebenzisa ilaphu lomqhaphu ukosula okokugqibela.Ukuba isikrufu sidinga ukugcinwa, umaleko wegrisi kufuneka usetyenziswe kumphezulu ukukhusela umhlwa.
Ukucoca umbhobho kulula kakhulu kunokucoca isikrufu, kodwa kubaluleke kakhulu.
1. Xa ulungiselela ukucoca umgqomo, ubushushu bombhobho bubekwe kwakhona kwi-200 ° C;
2. Krwela ibhrashi yentsimbi engqukuva kumbhobho wokubhobhoza kunye ne-drill yombane kwizixhobo zokucoca, uze usongele ibrashi yentsimbi ngemesh yocingo lobhedu;
3. Ngaphambi kokufaka isixhobo sokucoca kwi-barrel, ufafaze i-stearic acid kwi-barrel, okanye ufefe i-stearic acid kwi-copper wire mesh yesixhobo sokucoca;
4. Emva kokuba i-mesh yocingo yobhedu ingene kwi-barrel, qalisa i-drill yombane ukuyijikeleza, kwaye iyenze ngokwenziwa ukuba ihambe ngasemva naphambili de kube le ntshukumo yangaphambili nasemva ingabikho ukuchasana;
5. Emva kokuba i-mesh yocingo yobhedu ikhutshwe kwi-barrel, sebenzisa i-cotton cloth ye-cotton ukuze usule ngasemva nangaphambili kwi-barrel ukuze ususe nayiphi na i-resin yokucoca okanye i-fatty acid eseleyo;Emva kokusula okunjalo emva nangaphandle, ukucocwa kombhobho kugqityiwe.I-screw ecocekileyo kunye ne-barrel ilungele imveliso elandelayo!
