Mohato ka Mohato oa Polymer Extrusion process

Ho fepa lintho tse entsoeng ka polymer

Ts'ebetso ea extrusion e qala ka ho fepa thepa e tala ea polymer ka har'a hopper ea phepelo. Hopper e netefatsa ho ajoa le ho thibela li-blockages, tse thusang ho boloka ts'ebetso e tsitsitseng. Sekoti se ka hare ho barrel se qala ho potoloha, se hula li-pellets tsa polymer kapa phofo pele. Moralo oa screw, ho kenyeletsoa karo-karolelano ea bophara le bolelele ho isa ho bophara, e phetha karolo ea bohlokoa mabapi le hore na thepa e tsamaea hantle hakae. Sistimi ea taolo e lumella basebelisi ho fetola lebelo la screw le sekhahla sa phepelo, se thusang ho lokisa ts'ebetso bakeng sa lipolima tse fapaneng.

• Li-feed hoppers li etselitsoe ho thibela li-clog le ho netefatsa phepo e bonolo.
• Sekoti se fetisa, se hatella, 'me se qala ho futhumatsa polymer.
• Taolo ea mocheso ka har'a barrel e thusa ho ntlafatsa ts'ebetso ea ho qhibiliha.

Lithuto tsa pele li bonts'itse hore ho laola lebelo la screw le mocheso ho ama ka kotloloho tsela eo polymer e fepang le ho qhibiliha ka eona. Li-extruder tsa morao-rao tsa laboratori li sebelisa litsamaiso tse tsoetseng pele ho boloka phepelo e sebetsa hantle ebile e tsitsitse.

Ho qhibiliha le Plasticizing

Ha polymer e ntse e tsamaea ka har'a moqomo, e kena libakeng tse futhumetseng. Mocheso sebakeng se seng le se seng o eketseha butle-butle, o etsa hore polymer e be bonolo le ho qhibiliha. Ho potoloha ha screw le mocheso oa moqomo li sebetsa 'moho ho etsa polasetiki, ho e fetola boima bo tšoanang ba ho qhibiliha. Li-sensor tse behiloeng haufi le moqomo li lekola mocheso le khatello ho netefatsa hore polymer e qhibiliha ka har'a sebaka sa eona se nepahetseng sa ts'ebetso.

Taolo e nepahetseng ea mocheso le khatello e thusa ho thibela ho senyeha le ho netefatsa ho qhibiliha ho tsitsitseng. Tlhokomelo ea nako ea 'nete e nang le li-sensor tse tsoetseng pele le mekhoa ea spectroscopy e fana ka data e tsoelang pele, e lumellang bafuputsi ho fetola maemo ha ho hlokahala.

Ho kopanya le ho fetisa

Hang ha e qhibilihisoa, polymer e tlameha ho tsoakoa ka botlalo ho netefatsa hore e tšoana. Moralo oa screw, ho kenyelletsa likarolo tse kang litšitiso kapa libaka tse kopanyang, o thusa ho kopanya thepa le ho tlosa likhechana tse setseng tse tiileng. Ha screw e ntse e potoloha, e sutumelletsa polima e entsoeng ka ho qhibilihisoa ka pele, e e fetisetsa ho dae.
