Yintoni umatshini wokubumba iBlow

Ukubumba nge-blow yindlela yokwenzaukwenza iimveliso ezingenantongokusebenzisa uxinzelelo lwegesi ukuze kuvuthuze kwaye kuvuthuze iimbumba ezishushu ezinyibilikileyo ezivalekileyo kwisikhunta. Ukubumba okungenanto kukukhupha kwisikhunta kwaye kubeke isithuba esingenanto se-thermoplastic esisekwimeko yokuthamba kwisikhunta sokubumba. Emva koko ngokusebenzisa umoya ocinezelweyo, kusetyenziswa uxinzelelo lomoya ukuguqula isithuba esingenanto ecaleni komngxuma wokudaya, ngaloo ndlela kuvuthuza kube ziimveliso ezingenanto zentamo emfutshane.

Ukubumba okungenanto yeyona ndlela ibalulekileyo yokwenza iimveliso zeplastiki ezingenamntu.Phantse zonke ii-thermoplastics zingasetyenziselwa ukubumba izinto ezingenanto, ezifana ne-polyethylene, i-PVC, i-polypropylene, i-polystyrene, i-linear polyester, i-polycarbonate, i-polyamide, i-cellulose acetate kunye ne-poly acid formaldehyde resin, njl.

Ngale teknoloji yokubumba, ayinakukwazi kuphelavelisa ncinci ivolumuiibhotile zeemililitha ezininzi, kodwa zikwanayovelisaamawaka eelithaumthamo omkhuluiibhareli kunye neetanki zamanzi okugcina amanzi, kunye neebhola ezidadayo, iitanki zepetroli zeemoto kunye neekayak.

Zeziphi iimpawu ekufuneka zibe nazo iimveliso zokubumba ngomphunga?

1.Ukumelana nokuqhekeka koxinzelelo lwendalo: njengesikhongozeli, inamandla okuthintela ukuqhekeka xa idibana ne-surfactant;

2.Ukuqina komoya (ukumelana nokungangeni komoya): ibhekisa kwiimpawu ezithintela ukusasazeka ngaphandle kweoksijini, ikharbon diokside, initrogen kunye nomphunga wamanzi.

3.Ukumelana nomothuko: ukuze kukhuselwe iimpahla ezikwisikhongozeli, iimveliso kufuneka zibe nokumelana neempembelelo ezingenakwahlulwa ukusuka kubude bemitha enye.

4. Ukongeza, kukho ukumelana namayeza, ukumelana nokungashukumi, ukuqina kunye nokumelana nokuphuma kwamanzi.

Zithini iingenelo zokubumba nge-blow molding?

1. Isakhiwo esinomngxuma, esinodonga oluphindwe kabini sinokufunxa kwaye sisuse amandla ombane;

2. Uyilo oluguquguqukayo, olunemisebenzi ephezulu kunye neendleko zemveliso eziphantsi;

3. Itekhnoloji yokucubungula ingatshintsha ubukhulu be-embryo;

4. Ngethuba lokucubungula, ubukhulu bemveliso bunokutshintshwa ngokuthanda ngaphandle kokuphucula ukungunda;

5. Ukubumba ngoxinzelelo oluphantsi (uxinzelelo lwangaphakathi lwesikhunta luncinci kakhulu kunolo lokubumba ngenaliti), ukuze kuphuculwe uzinzo olunemilinganiselo, ukumelana nokugqwala kweekhemikhali kunye nokusebenza kobushushu obuphezulu;

6.Ukwahluka kwendibano: isikrufu sokuzicofa, i-die insert, i-fastener yokwandisa i-rivet;

7.Isikhunta esilula, iindleko eziphantsi kunye nomjikelo omfutshane wokucubungula;

8. Isampuli yokubumba enexabiso eliphantsi ingaveliswa ngokukhawuleza.

Ukubumba nge-blow yinkqubo yokuvelisa apho kwakhiwa khona iindawo zeplastiki ezingenanto: Ikwasetyenziselwa ukwenza iibhotile zeglasi. Ngokubanzi, kukho iintlobo ezintathu eziphambili zokubumba nge-blow:ukubumba i-extrusion blow molding, ukubumba i-injection blow molding, kunye nokubumba i-injection stretch blow molding.

Iimbonakalo:

Ukusebenza okuzinzileyonge-PLC ephucukileyo.

.Ukudlulisa iifomu zangaphambili ngokuzenzekelayokunye nomthuthi.

.Ukungena okunamandlakunye nokusasazwa kobushushu okuhle nokukhawulezileyo ngokuvumela iibhotile zijikeleze zodwa kwaye zijikeleze kwiireyile ngaxeshanye kwi-infrared preheater.

.Ukulungiswa okuphezuluukwenza i-preheater ikwazi ukufudumeza ii-preforms ngokweemilo ngokulungelelanisa ityhubhu yokukhanya kunye nobude bebhodi ebonakalisayo kwindawo yokufudumeza kwangaphambili, kunye nobushushu obungapheliyo kwi-preheater ngesixhobo se-thermostatic esizenzekelayo.

.Ukhuseleko oluphezulungesixhobo sokhuseleko esizitshixa ngokuzenzekelayo kwisenzo ngasinye soomatshini, nto leyo eya kwenza iinkqubo zibe kwimeko yokhuseleko xa kukho ukuphazamiseka kwenkqubo ethile.

Ngokusisisekoukubumba ngesibethoyiplastiki engenanto kwaye yenze isikhongozeli esidibanisa la macandelo. Ifumaneka ngeemilo nobukhulu obahlukeneyo. Ukubumba nge-blow kunye nokubumba nge-injection zezinye zeendlela ezisetyenziswa kakhulu kwaye zisetyenziswa kakhulu kule ndlela.velisa iindawo zeplastiki ezikumgangatho ophezulu ngexabiso eliphantsingoko ke le yindlela entle nengabizi kakhulu. Ukubumba ngokufutha yindlela endala esetyenziselwa ukwenza izinto ezingenanto. Kwi-Blow molding kukho izinto ezininzi ezibandakanyekayo ezifana "uhlobo lweplastiki, isantya, isantya, ubushushu.Umoya ngomnye wemiba ebalulekileyo kwaye udlala indima ebalulekileyo ekubumbeni ngebhombu. Umoya utyhalelwa kwibhombu ukuze uyandise kwaye uyinike imo oyifunayo. Inkqubo yokubumba ngebhombu ilula kakhulu, isetyenziswa kakhulu kwaye ibandakanya oomatshini abaxabisa kancinci, ukwenza iibhotile zeplastiki kusetyenziswa le nkqubo kubiza kakhulu xa kuthelekiswa nokubumba ngenaliti. Kwibhombu, ukubumba ngebhombu akufuneki ukuze kwenziwe ukubumba ngebhombu ngokuchanekileyo okuphezulu.

Ukubumba nge-blow – yinkqubo yokuvelisa ekhethekileyo apho kwakheka khona iinxalenye zeplastiki ezingenamngxuma kwaye zinokudityaniswa.

Aumatshini wokubumba ngesibethoisetyenziswa kakhulu kwimveliso yeziselo zorhwebo. Umatshini wokubumba ibhotile yeplastiki udala ngokweresiphi, umzekelo ucacisa amandla ebhotile ekufuneka yenziwe. Lo matshini unezibumba, umlawuli we-logic onokucwangciswa, kunye nezixhobo zoomatshini neze-elektroniki.
