Bakeng sa lisebelisoa tsa polyethylene

Joalo ka ha ho tsebahala, ketsahalo ea "letlalo la shaka" hangata e etsahala ha ho fetisoa lithapo le likhoele tsa polyethylene tse sirelelitsoeng kapa tse kentsoeng, haholo-holo ha ho ntšoa polyethylene e tlase-tlase (LLDPE) kapa polyethylene e tlase haholo (ULDPE kapa POE).Lisebelisoa tsa polyethylene tse atolositsoeng (ebang li-peroxide cross-linking kapa silane cross-linking) le tsona ka linako tse ling li ba le ketsahalo ea "letlalo la shaka", ka lebaka la ho se nahane ka mokhoa o lekaneng oa tsamaiso ea lubrication ka mokhoa oa thepa.Tloaelo ea hajoale ea machabeng ke ho kenyelletsa palo ea morao-rao ea li-fluoropolymers foromong, empa litšenyehelo li holimo ebile ts'ebeliso e lekanyelitsoe.

Ka chelete e nyane easilicone e phahameng ea boima ba molek'hule(0.1-0.2%) ho polyethylene kapa polyethylene e amanang le sefapano e ka thibela ka katleho ho hlahisa "letlalo la shaka".Ka nako e ts'oanang, ka phello ea eona ea lubrication, e ka fokotsa ka katleho torque ea extrusion ho thibela koloi e hulang ho emisa ka lebaka la ho tlala.

Silicone e sebelisoang e le setlolo, ka lebaka la tlatsetso e fokolang, e tlameha ho ajoa ka mokhoa o lekanang ka har'a thepa e le hore e sebetse nakong ea ts'ebetso.Ka lebaka la ho se sebetse ha lik'hemik'hale tsa silicone, e ke ke ea itšoara ka lik'hemik'hale ka likarolo tsa foromo.Ho kgothaletswa hore fektheri ea thepa ea thapo e kopane ka mokhoa o ts'oanang oa silicone ka mokhoa oa polasetiki oa granulation ho thusa ho sebelisa fektheri ea cable.

Ka lebaka la ho ba teng ha li-flame retardants tse ngata (phofo ea diminerale) ka lik'hemik'hale tsa cable tsa HFFR, tse etsang hore ho be le viscosity e phahameng le ho phalla ho fokolang nakong ea ts'ebetso;The viscosity e phahameng e etsa hore ho be thata hore enjene e hule nakong ea extrusion, 'me metsi a futsanehileng a etsa hore ho be le sekhomaretsi se senyenyane se hlahisoang nakong ea extrusion.Kahoo, ha fektheri ea cable e ntša lithapo tse se nang halogen, katleho ke 1/2-1/3 feela ea thapo ea polyvinyl chloride.
