Kwicandelo lokwenziwa kweeplastiki, oomatshini be-twin screw pelletizing basebenza njengezinto zobugcisa ezimangalisayo, beguqula iplastiki enyibilikisiweyo ibe zii-pellets ezifanayo ezisebenza njengezakhi zemveliso ezininzi. Ukusuka kwiifilimu zokupakisha ukuya kwizinto zeemoto, ii-twin screw pelletizers zingumqolo wamashishini amaninzi. Esi sikhokelo sibanzi sijonga kwiingxaki zoomatshini be-twin screw pelletizing, sihlola imigaqo yokusebenza kwabo, iingenelo ezizodwa, kunye nokusetyenziswa okwahlukeneyo.
1. Ukuqonda i-Anatomy ye-Twin Screw Pelletizer
Embindini we-pelletizer yee-screw ezimbini kukho izikrufu ezimbini ezijikelezayo, ezilungelelaniswe ukusebenza ngaxeshanye. Ezi zikrufu zigcinwa ngaphakathi kwi-barrel, zihlala zihlulwe kwaye zifudunyezwe ukuqinisekisa ukunyibilika, ukuxubana, kunye nokuchithwa okufanayo kweplastiki.
2. Uhambo lwePlastiki ngeTwin Screw Pelletizer
Iplastiki enyibilikisiweyo, edla ngokutyalwa kwi-extruder ephuma phezulu, ingena kwicandelo lokutya kwi-pelletizer barrel. Njengoko izikrufu zijikeleza, zihambisa izinto ecaleni kwe-barrel, ziyenza ixutywe kakhulu, ifane, kwaye icinezelwe.
3. Ukubumba nokusika iPlastiki enyibilikayo: Amandla eDie Plate
Iplastiki enyibilikisiweyo inyanzeliswa kwipleyiti yedayi eyenzelwe ngokukodwa, inqanaba lokugqibela lenkqubo yokufakelwa kwepellet. Ubume bepleyiti yedayi bumisela imo kunye nobukhulu beepellets, ngokuqhelekileyo ezisilinda okanye ezifana nentambo.
4. Ukuphola kunye nokuQina: Ukuguqula iPlastiki enyibilikisiweyo ibe ziiPellets
Emva kokuphuma kwipleyiti yokudaya, ii-hot pellets zipholiswa ngokukhawuleza, nokuba ngomoya, ngamanzi, okanye ngeendlela zokupholisa nge-vacuum. Oku kupholisa ngokukhawuleza kuyawaqinisa ama-pellets, kuwathintela ekudibaneni.
5. Iingenelo zeeMatshini zePelletizing zeTwin Screw: Ukusebenza kakuhle, ukuSebenza ngeendlela ezahlukeneyo, kunye noMgangatho weMveliso
Oomatshini bokwenza iipelletizing ezizi-screw ezimbini banika indibaniselwano enomtsalane yokusebenza kakuhle, ukuguquguquka, kunye nomgangatho wemveliso, nto leyo eyenza ukuba babe lukhetho olukhethwayo kwiintlobo ngeentlobo zezicelo zokwenza iplastiki:
Amanqanaba aphezulu eMveliso: Iipelletizers ze-Twin screw zinokufumana amazinga aphezulu emveliso xa kuthelekiswa neepelletizers ze-single screw, nto leyo ezenza zilungele imveliso yeplastiki enkulu.
Ukuxuba Okugqwesileyo kunye Nokudibanisa: Izikrufu ezijikelezayo zibonelela ngokuxuba okugqwesileyo kunye nokudibanisa iplastiki enyibilikayo, nto leyo ebangela ukuba iipellets zibe neempawu ezifanayo kunye neziphene ezinciphileyo.
Ukuchithwa kunye nokuVula: Iipelletizers ze-Twin screw zisusa ngokufanelekileyo i-volatiles kunye nokufuma kwi-plastic melt, ziphucula umgangatho we-pellet kunye nokulungiswa kwe-downstream.
Ukuguquguquka kwezinto ezahlukeneyo: Iipelletizers ze-Twin screw zinokusingatha uluhlu olubanzi lwezinto ze-thermoplastic, kubandakanya i-polyethylene, i-polypropylene, i-PVC, kunye neeplastiki zobunjineli.
Iipellets ezikumgangatho ophezulu zeempawu zemveliso eziphuculweyo: Ukuma okufanayo, ubungakanani, kunye neempawu ezifanayo zeplastiki yepelletized enezikrufu ezimbini kunceda ekuphuculeni umgangatho wemveliso kunye nokusebenza kwayo.
6. Iindlela ezahlukeneyo zokusetyenziswa kwee-Twin Screw Pelletizing Machines: Ihlabathi leeMveliso zePlastiki
Oomatshini bokwenza iipelletizing ezinezikrufu ezimbini bafumaneka kakhulu kushishino lweplastiki, bevelisa iipellet ezisisiseko seemveliso ezininzi:
Iifilimu zokuPakisha: Iifilimu zeplastiki zokupakisha ukutya, iziselo, kunye neempahla zabathengi zenziwa kakhulu kusetyenziswa iplastiki enezikrufu ezimbini.
Iipayipi kunye nezinto ezifakelwayo: Iplastiki enezikrufu ezimbini isetyenziswa ekuveliseni iipayipi kunye nezinto ezifakelwayo kwiinkqubo zemibhobho, zokwakha kunye nokunkcenkceshela.
Izinto Ezisetyenziswa Kwizithuthi: Iibhampa, izinto ezisetyenziswa ngaphakathi, kunye nezinye izinto ezisetyenziswa kwiimoto zihlala zenziwe ngeplastiki enee-screw ezimbini.
Impahla: Iifayibha ezenziweyo zempahla, iikhaphethi, kunye nokusetyenziswa kwemizi-mveliso zithathwe kwiplastiki enezikrufu ezimbini.
Izixhobo: Izixhobo zeplastiki ezikwizixhobo zasekhaya, ezifana neekhabhathi kunye namalungu angaphakathi, zihlala zenziwe ngeplastiki enezikrufu ezimbini.
7. Isiphelo: Oomatshini Bokutsala Iipilisi Zezikrufu Ezimbini – Ukuqhuba Ubuchule Kwimveliso Yeplastiki
Oomatshini bokwenza iipelletizing ezizii-screw ezimbini batshintshe ishishini leplastiki, ukusebenza kakuhle kwazo, ukuguquguquka kwazo, kunye nokukwazi ukuvelisa iipellet ezikumgangatho ophezulu nto leyo eyenza ukuba zibe zizixhobo ezibalulekileyo kubavelisi kwihlabathi liphela. Njengoko imfuno yeplastiki iqhubeka ikhula, iipelletizing ezizii-screw ezimbini ziya kuhlala ziphambili kubuchule bokuvelisa izinto ezintsha, ziqhuba inkqubela phambili kwisayensi yezinto eziphathekayo, ubuchwepheshe bokucubungula, kunye neendlela zokuvelisa ezizinzileyo.
