Ha ho etsoa profil, lubricant e sebelisitsoeng e fapane ka lebaka la litsamaiso tse fapaneng tse tsitsitseng.Lenaneong la ho tsitsisa letsoai le etellang pele, acid ea stearic, glyceryl stearate le boka ba polyethylene e ka khethoa e le mafura;tsamaisong ea botsitso ea zinki e se nang chefo le sistimi e sa tloaelehang ea motsoako oa lefatše, asiti ea stearic, butyl stearate, parafine, boka ba boka le calcium stearate e ka khethoa e le mafura;ka foromo ea organic tin, calcium stearate, parafine, boka ba polyethylene e oxidized e ka khethoa e le mafura.Lintho tse ka sehloohong tsa lubricant tse tloaelehileng ke tse latelang:
(1) Calcium stearate
Phofo e tšoeu, ntlha e qhibilihisang 148-155 ℃, e se nang chefo, e nang le lubricity e babatsehang le ts'ebetso, ha ho na tšilafalo ea sulfide, e sebelisoang hammoho le letsoai la lead le sesepa sa loto, e ka ntlafatsa lebelo la gel, 'me tekanyo ea kakaretso ke 0.1-0.4PHR.
(2) Polyethylene boka
Phofo e tšoeu, ntlha e nolofatsang e ka bang 100-117 ℃.Ka lebaka la boima ba eona ba limolek'hule tse batlang li le holimo, sebaka se phahameng sa ho qhibiliha le ho feto-fetoha ha maemo ho tlase, e boetse e bonts'a phello e hlakileng ea ho tlotsa ka mocheso o phahameng le sekhahla sa ho kuta.E loketse PVC e thata ea single le twin screw extrusion, e nang le palo e tloaelehileng ea 0.1-0.5PHR.
(3) Oxidized polyethylene boka
Phofo e tšoeu kapa e mosehla kapa karoloana, boka ba polyethylene e nang le oxidized e ntse e sa lumellane le PVC, le hoja e na le lihlopha tse nyenyane tsa polar, empa katleho ea lubrication e phahame, e ka ntlafatsang lubrication pakeng tsa polymer le tšepe, ho ntlafatsa katleho ea extrusion, ho ntlafatsa ho hasana ha li-colorants, le ho fana ka lihlahisoa pepeneneng le ho benya.Tekanyetso 0.1-0.5PHR.
(4) Asiti ea Stearic
Likaroloana tse tšoeu kapa tse mosehla, ntlha e qhibilihang ke 70-71 ℃.E fetoha butle butle ho 90-100 ℃.E sebelisoa e le setlolo sa kantle ha ho sebetsoa PVC e thata.Chelete ka kakaretso ke 0.2-0.5PHR, 'me e na le phello ea ho thibela chromatography scaling, empa ho bonolo ho fafatsa serame haeba chelete e ngata haholo.
(5) boka ba parafine
Melting point 57-63 ℃, ntle le lihlopha tsa polar, ke setlolo se tloaelehileng sa kantle.Ka lebaka la boemo ba eona bo tlase ba ho qhibiliha, mouoane habonolo, le viscosity e tlase ea ho qhibiliha, e ka bapala karolo ea ho tlotsa sebakeng se moqotetsane.E loketse ho extrusion ka li-scruders tse le 'ngoe le tse mafahla, ka tekanyo e akaretsang ea 0.1-0.8PHR.Sehlahisoa sena se na le ponahalo e fokolang 'me se bonolo ho fetoha tšoeu.
Ha e le hantle, ho fumanoa hore ha litlolo tse peli kapa ho feta li sebelisoa hammoho, li na le liphello tse fapaneng ho feta ha li sebelisoa li le mong.Ha ho etsoa lisebelisoa tsa profil, boholo ba tsona li tsoakane.Sistimi e ts'oanang le litšoaneleho tsa mafura a tloaelehileng li akaretsoa ka tsela e latelang:
(1) Calcium stearate - Parafine (polyethylene wax) tsamaiso ea lubrication
Tšebeliso ea calcium stearate feela ka foromo e ka potlakisa polasetiki, ea ntlafatsa viscosity e qhibilihisitsoeng, ea eketsa torque, 'me ea ba le phello e itseng ea ho senya.Tšebeliso ea parafine feela e bonts'a polasetiki e liehileng, torque e fokotsehileng, 'me ha ho na phello e senyang.Ha calcium stearate le boka ba parafine (polyethylene boka) li kopantsoe ka tekanyo e itseng, e bontša phello e ntle, 'me boleng ba torque ea thepa bo ka fokotseha haholo.Sena ke hobane parafine e kenella ka har'a limolek'hule tsa calcium stearate, e matlafatsa lubrication, e bonts'a phello e matla ea synergistic, le ho ntlafatsa ho hasana ha lubricant.
(2) Stearic acid - Parafine (polyethylene boka) tsamaiso ea ho tlotsa
Mochine ona o tšoana le oa calcium stearate - Parafine (polyethylene wax) tsamaiso, e ka ntlafatsang botsitso ba mocheso oa foromo, ho fokotsa ho fokotseha, ho ntlafatsa metsi, le ho nolofatsa ho senya.
(3) Oxidized polyethylene boka - esters - calcium stearate
Ha boka ba boka ba polyethylene, ester le calcium stearate li sebelisoa hammoho, nako ea polasetiki ho hlakile hore e lelefalitsoe ka ho eketseha ha boka ba boka ba polyethylene, ha boka ba boka ba polyethylene, boka ba parafine, ester le calcium stearate li sebelisoa hammoho, nako ea polasetiki e eketseha pele. e ntan'o fokotseha ka keketseho ea boka ba boka ba polyethylene e oxidized, e bontšang phello e hlakileng ea synergistic.
Qetellong, ha u ithuta foromo ea profil ea PVC, ha ua lokela ho utloisisa feela litšobotsi le mesebetsi ea setlolo se seng le se seng, empa hape le phello ea synergistic pakeng tsa bona.Ntle le moo, foromo ea profil ea PVC e hloka ho lokisoa le ho fetoloa ho latela phapang ea lisebelisoa tsa ho sebetsa le hlobo.
