Butle-butle-Mofuta o le Mong Screw

Sekurufu se le seng sa butle-butle se entsoe ka tšepe ea 38CrMoAla. Lintho tse tala li bohlokoa haholo bakeng sa ts'ebetso ea "screw", 'me re khetha litšepe tse matla le tse sa senyeheng ho tsoa ho baetsi ba litšepe ba tsebahalang ba Machaena ba fihlelang maemo a naha (GB/T 3077).

Nanhaiya's tgradual-type single screw extruder e arotsoe ka likarolo tse tharo ho latela mosebetsi oa tsona. Botebo ba liphala karolong e 'ngoe le e' ngoe bo fokotseha ka tatellano ntle le liphetoho tse bonahalang tsa tšohanyetso, ho theha sebopeho se boreleli, "butle-butle".

Karolo ea phepelo hangata e nka 20% -30% ea kakaretso ea bolelele ba screw. Karolo ea khatello, karolo e bohareng ea screw, e ikarabella bakeng sa karolo e kholo ka ho fetisisa (40% -50%) mme ke motheo oa sebopeho sa butle-butle. Botebo ba lekolilo bo qala ka boholo ba eona karolong ea ho fepa 'me butle-butle le ka mokhoa o lekanang bo fokotseha ka bolelele ba screw, ho etsa "compression zone."

Karolo ea homogenization e tsoela pele ho kopanya le ho tsitsisa ho qhibiliha, ho netefatsa hore mocheso o ts'oanang o qhibiliha le viscosity. Thepa e ntan'o isoa hloohong ea lefu ka khatello e tsitsitseng le lebelo la phallo, ho netefatsa boleng bo tsitsitseng ba sehlahisoa se extruded.

Libarele tsa mofuta o le mong tsa Nanhaiya tsa butle-butle li bile teng ka R&D le lintlafatso tse ngata 'me joale li kopantsoe le mela ea tlhahiso ea bahlahisi ba fapaneng, ho fihlela ts'ebetso ea maemo a holimo. Re fana ka tiisetso ea lilemo tse 1-2, ho latela tekanyo e khethehileng ea tlatsetso ea thepa. Libarele tsa Nanhaiya li kena ts'ebetsong ea nitriding, ka lesela le teteaneng la 0.8 ~ 2m ea alloy ea nickel-tungsten e tšubuhlellanang libakeng tse tloaelehileng haholo. Sena se eketsa boima ba holim'a barrel ke HRC55 ~ 62, ho matlafatsa khanyetso ea ho apara ka makhetlo a 2-3.

Tekheniki Parameter

Tšobotsi le Tšebeliso

Nanhaiya's single screw extruder ea butle-butle e na le sebopeho sa methati e meraro se nang le likarohano tse hlakileng tsa ts'ebetso. Mekhoa e lumellanang ea ts'ebetso (mocheso, lebelo, le khatello ea morao) e ka fetoloa ka mokhoa o utloahalang, e leng ho etsang hore ts'ebetso e be bonolo haholo ho feta ka li-screws tse khethehileng.

Taolo e Bonolo ea Mocheso: Boemo ba mocheso oa mekhahlelo e meraro bo latela molao-motheo oa "ho eketseha ha gradient". Karolo ea ho fepa e na le mocheso o tlaase ka ho fetisisa (o hlokehang feela ho nolofatsa lintho tse bonahalang, tse kang 50-80 ° C bakeng sa ts'ebetso ea PE), karolo ea compression e ntse e eketseha butle-butle mocheso (ho fihla sebakeng sa ho qhibiliha, joalo ka 160-180 ° C bakeng sa PE), 'me karolo ea homogenization e tsitsitse sebakeng sa ho qhibiliha (joalo ka 180-200 ° C). Litokiso tse rarahaneng tsa mocheso oa lehae ha li hlokehe.

Linear Correlation between Speed ​​and Output: Ka har'a lebelo le utloahalang (hangata 30-150 rpm), tlhahiso e eketseha hoo e ka bang ka ho lekana ka lebelo la sekoti, e leng ho felisang tlhokahalo ea liphetoho khafetsa tsa matšeliso a mokokotlo. Sena se etsa hore e be se loketseng basebelisi ba li-novice mme se thusa tlhahiso e kholo e tsoelang pele le e tsitsitseng (joalo ka lihora tse 24 tsa extrusion e tsoelang pele ea liphaephe le lifilimi).

Tlhokahalo ea khatello e tlase ea mokokotlo: Botebo ba "screw groove" karolong ea homogenization bo lula bo sa fetohe, 'me ho hlokahala feela khatello e tloaelehileng ea mokokotlo ea 3-8 bar ho netefatsa ho tšoana ho qhibilihang. Khatello e feteletseng ea mokokotlo e tla eketsa torque ea screw, ho eketsa tšebeliso ea matla, esita le ho etsa hore ho be le mocheso o feteletseng, 'me "mamello" ea ts'ebetso e phahame.

Thepa ea "screw extruder" ea mofuta oa butle-butle e loketse ho hlahisa lifilimi tsa PE (polyethylene) (joalo ka sephutheloana sa lijo, mekotla ea mabenkele a lisuphamakete, le mekotla e sa keneng ea metsi), tepi ea PP (polypropylene) le filimi ea PVC (polyvinyl chloride). E ka boela ea hlahisa liphaephe tsa drainage tsa PVC, lipeipi tsa metsi tsa PPR, lipeipi tsa khase tsa PE, le profil ea lifensetere tsa polasetiki. E ka boela ea hlahisa likotlolo tsa polasetiki tsa PE, libakete tsa polasetiki tsa PP, trunking ea cable ea PVC, le mabokose a polokelo ea polasetiki. E ka boela ea hlahisa lisebelisoa tsa PE le PP tse tsosolositsoeng hape tsa hlahisa liphaephe tsa PE tse tletseng ho fihla ho 10% calcium carbonate.

Lintlha tsa Sehlahisoa

Mekhoa e tsoetseng pele ea ho futhumatsa, ho sebetsa ka mokhoa o nepahetseng, le lits'ebetso tsa nitriding li netefatsa ts'ebetso e felletseng ea likarolo tsa mantlha.

Libaka tse tlokotsing tsa screw le barrel li matlafatsoa ka lera la nickel-tungsten alloy, ho fihlela lera le teteaneng la 0.8-2.0mm le ho ntlafatsa haholo ho hanyetsa ho apara.
