Twin screw extruder e sebelisoa haholo bakeng sa phetoho ea 'mele ea li-polymers, hape e ka sebelisoa bakeng sa extrusion ea lihlahisoa tse bōpiloeng. Litšobotsi tsa eona tsa ho iphepa li betere, 'me e na le mesebetsi e betere ea ho tsoaka, ho ntša moea, le ho itlhoekisa ho feta screw extruder e le 'ngoe. Ka ho kopana ha mefuta e fapaneng ea li-screw elements, "twin-screw extruder" e nang le ts'ebetso ea ho ntša metsi e entsoeng ka mokhoa oa li-blocks tsa mohaho e ka sebelisoa likarolong tse latelang.
- Tlhahiso ea masterbatch
Motsoako oa likaroloana tsa polasetiki le li-additives ke master batch. Li-additives li kenyelletsa li-pigment, li-filler le li-additives tse sebetsang. The twin-screw extruder ke lisebelisoa tsa bohlokoa tsa mohala oa tlhahiso ea masterbatch, o sebelisetsoang homogenization, ho hasana le ho kopanya li-additives ka har'a matrix a polymer.
- Phetoho ea ho kopanya
Fana ka ts'ebetso e ntle ka ho fetisisa ea ho kopanya lipakeng tsa matrix le li-additives, li-filler. Fiber ea khalase ke eona ntho ea bohlokoa ka ho fetisisa e matlafatsang, empa likhoele tse ling le tsona li ka kopanngoa le li-polymer carriers. Ka ho eketsa likhoele le ho kopanya le li-polymers, lisebelisoa tse nang le matla a phahameng le ho hanyetsa tšusumetso e matla li ka fumanoa, 'me ka nako e ts'oanang, boima le litšenyehelo li ka fokotsoa.
- Qheketsa
Ka lebaka la ho kopana ha li-screws tse peli, mokhoa oa ho kuta oa thepa sebakeng sa meshing o tsoela pele ho ntlafatsa bokaholimo ba thepa le ho ntlafatsa phello ea ho tima, e le hore "twin-screw extruder" e be le ts'ebetso e ntle ho feta sekoahelo se le seng se khathetseng. extruder. Tshebetso ea ho felloa ke matla.
- Extrusion e tobileng
The twin-screw extruder e ka boela ea kopanya ho kopanya le ho bopa extrusion. Ka ho sebelisa hlooho e khethehileng le thepa e loketseng ea ho theosa le noka, e ka hlahisa lihlahisoa tse felileng ka mokhoa o atlehileng haholoanyane, tse kang lifilimi, lipoleiti, liphaephe, joalo-joalo. Extrusion e tobileng e ka siea mehato ea ho pholisa le ho pelletizing le ho futhumatsa hape le ho qhibiliha, 'me thepa e tlas'a khatello e fokolang ea mocheso le khatello ea ho kuta. Ts'ebetso eohle e ka boloka matla mme foromo e ka fetoloa habonolo.
