Ngokunxuseneyo UkuJikelezisa iTwin Screw Extruder

Uyilo lwewele umva{0}}isikrufu silula. Ngenxa yezikrufu ezibini ezijikelezayo kumacala achaseneyo kwaye zineendawo zokunxibelelana ezimbalwa phakathi kwazo, iimfuno ezichanekileyo zokulingana phakathi kwezikrufu ziphantsi. Kwi-counter rotating twin-screw extruder, uthutho lwemathiriyeli luyafana nemowudi yokufuduka elungileyo kwimpompo yegiya. Uphawu lwale extruder yisantya esiphantsi sokujikeleza, esinciphisa ubushushu obuveliswa kukucheba kunye nokunciphisa umngcipheko wokubola kwezinto. Ke ngoko, ineemfuno ezisezantsi zozinzo lwe-thermal yezixhobo kwaye ilungele ngakumbi ukubunjwa kunye nokusetyenzwa kwezixhobo ezibuthathaka zobushushu ezifana nePVC.

I-twin screw extruder ejikelezileyo echaseneyo inobuchule obuphezulu bokuhambisa, ukukhupha okungcono kunye neziphumo zokunyibilika. Nangona ukusasazwa kwayo kunye nokusebenza kokuxuba kungaphantsi kancinci, kunokumisela ngcono uxinzelelo lwentloko oluzinzileyo, iyenze ibe lolona khetho lufanelekileyo lokukhutshwa ngokuthe ngqo kweemveliso. Ukongeza, inkqubo ye-plasticization ye-granulation yangaphambili inokushiywa kwaye i-PVC powder inokucutshungulwa ngokuthe ngqo ukunciphisa iindleko zemveliso.
Ngokwemveli, iwele le-anisotropic conical -screw extruder isetyenziswa ikakhulu ukukhupha i-polyvinyl chloride (PVC) iimveliso. Nangona kunjalo, kwiminyaka yakutshanje, ezinye izenzo zasekhaya zibonise ukuba i-anisotropic conical twin{2}}i-screw extruder ingasetyenziswa ngempumelelo kwi-extrusion ye-polyolefin (efana ne-polyethylene, i-PE) imibhobho. Eyona nto ikhuthazayo yokusebenzisa iwele le-anisotropic conical -isikrufu esikhuphayo sokukhupha imibhobho yepololefin kukugcina amandla kunye nokunciphisa iindleko.

Umzekelo, i-65mm ye-conical twin edayamitha eyi-65mm{1}}ye-screw extruder ene-screw spacing ye-132um inamandla okuqhuba injini angama-37kW kuphela, ngelixa i-75mm okanye i-80mm esinye isikruru se-extruder sikholisa ukuba namandla okuqhuba angekho ngaphantsi kwe-90kW. Oku kuthetha ukuba, kwimveliso efanayo okanye efanayo, i-counter ejikelezayo ye-conical twin{8}}i-screw extruder inokubonelela ngokusebenza kakuhle kwamandla.
Kubalulekile ukuqaphela ukuba ngenxa yeyantlukwano ebalulekileyo kwiimpawu zokuhamba phakathi kwe-polyolefin enyibilikayo kunye ne-polyvinyl chloride enyibilikayo, xa usebenzisa i-anisotropic conical twin eyilwe ekuqaleni{0}}i-screw extruder ye-PVC ukuya kwi-extrusion yombhobho we-polyolefin, uyilo lwe-screw kufuneka luhlengahlengiswe ukuqinisekisa ukusetyenzwa okusebenzayo kwemathiriyeli ye-pololefin, kunye nokuguqulwa okuhambelanayo kunye nokuguqulwa kwee-extrus.

I-co rotating twin-i-screw extruder, ngenxa yeempawu zayo ezilungiselelwe kakhulu kunye nomxholo ophezulu weteknoloji, iyilwe ngokuchaneka okukhulu kunye nobunzima; Ngokuphathelele ukugcinwa, ixesha elininzi kunye nomgudu kufuneka kutyalwe kulawulo oluhle. Icala elichaseneyo newele{2}}i-screw extruder iphumelele inkoliseko yabanye abasebenzisi ngoyilo lwayo olucocekileyo nolucacileyo, ngakumbi kwiimeko zesicelo ezisukela uzinzo kunye nokuthembeka.
I-opposite ejikelezayo ye-screw extruder sisixhobo esikhethekileyo esilungele ukubunjwa kwe-extrusion ye-PVC ezahlukeneyo zomgubo. Ixhotyiswe ngoomatshini abahlukeneyo kunye noomatshini abancedisayo, inokuvelisa iintlobo ezahlukeneyo zemibhobho yeplastiki yePVC, iiprofayili, iipleyiti, amashiti, imivalo kunye neepelisi.
 

Iifayile ezishisayo: i-twin screw extruder emeleneyo ejongene necala elijikelezileyo, iTshayina idibane necala elijikelezayo elijikelezayo abavelisi be-extruder, ababoneleli, umzi-mveliso
