Ekwakhiweni kwephrofayili, i-lubricant esetshenzisiwe ihlukile ngenxa yezinhlelo ezizinzile ezihlukene.Kuhlelo lokuzinzisa usawoti oholayo, i-stearic acid, i-glyceryl stearate ne-polyethylene wax ingakhethwa njengama-lubricant;ohlelweni lokuqiniswa kwenhlanganisela ye-calcium zinc engenabuthi kanye nesistimu yokuqiniswa kwenhlanganisela yomhlaba engavamile, i-stearic acid, i-butyl stearate, upharafini, pe wax kanye ne-calcium stearate ingakhethwa njengamafutha;ku-organic tin formula, i-calcium stearate, upharafini, i-polyethylene wax ene-oxidized ingakhethwa njengama-lubricant.Izici eziyinhloko zokugcoba ezivamile zimi kanje:

(1) I-calcium stearate
Impushana emhlophe, indawo encibilikayo engu-148-155 ℃, ayinabo ubuthi, ukuthambisa okuhle kakhulu nokucutshungulwa, akukho ukungcoliswa kwe-sulfide, esetshenziswa kanye nosawoti omningi oyisisekelo nensipho yomthofu, ingathuthukisa ijubane lejeli, futhi umthamo ngokuvamile ngu-0.1-0.4PHR.
(2) I-polyethylene wax
Impushana emhlophe, indawo yokuthambisa icishe ibe ngu-100-117 ℃.Ngenxa yesisindo sayo samangqamuzana aphakeme uma kuqhathaniswa, indawo ephezulu yokuncibilika kanye nokuntengantenga okuphansi, kuphinda kubonise umphumela wokugcoba osobala ezingeni lokushisa eliphezulu kanye nezinga lokugunda.Ifanele i-PVC eqinile eyodwa kanye ne-twin screw extrusion, ngenani elivamile elingu-0.1-0.5PHR.
(3) I-polyethylene wax eyenziwe nge-oxidized
Impushana emhlophe noma ephuzi noma izinhlayiyana, i-polyethylene ene-oxidized namanje ayihambisani ne-PVC, nakuba iqukethe inani elincane lamaqembu e-polar, kodwa ukusebenza kahle kokugcoba kuphezulu, okungathuthukisa ukugcotshwa phakathi kwe-polymer nensimbi, ukuthuthukisa ukusebenza kahle kwe-extrusion, ukuthuthukisa ukuhlakazwa kwama-colorants, futhi inikeze imikhiqizo ukubonakala okuhle nokucwebezela.Umthamo 0.1-0.5PHR.

(4) I-Stearic acid
Izinhlayiya ezimhlophe noma eziphuzi, indawo encibilikayo engu-70-71 ℃.Ishintsha kancane kancane ku-90-100 ℃.Isetshenziswa njenge-lubricant yangaphandle ekucubunguleni i-PVC eqinile.Inani ngokuvamile lingu-0.2-0.5PHR, futhi linomthelela wokuvimbela ukukala kwe-chromatography, kodwa kulula ukufafaza isithwathwa uma inani likhulu kakhulu.

(5) I-wax kapharafini
Iphuzu lokuncibilika elingu-57-63 ℃, ngaphandle kwamaqembu e-polar, liwuketshezi oluvamile lwangaphandle.Ngenxa yokuncibilika kwayo okuphansi, ukuhwamuka kalula, kanye ne-viscosity encibilikayo ephansi, ingadlala indima yokugcoba ebangeni elincane.Ifanele ukukhishwa ngama-scruder angama-single kanye namawele, ngomthamo ojwayelekile ongu-0.1-0.8PHR.Lo mkhiqizo unokungacaceli kahle futhi kulula ukuwushintsha ube mhlophe.
Eqinisweni, kutholakala ukuthi lapho amafutha amabili noma ngaphezulu esetshenziswa ndawonye, ​​anemiphumela ehlukile kunalapho esetshenziswa yedwa.Ekwakhiweni kwezinto zephrofayili, iningi lazo lixubene.Isistimu yokufanisa nezici zokugcoba ezivamile zifinyezwa ngale ndlela elandelayo:
(1) Calcium stearate – Upharafini (i-polyethylene wax) uhlelo lokuthambisa
Ukusetshenziswa kwe-calcium stearate iyodwa kufomula kungasheshisa ukwenziwa kwepulasitiki, kuthuthukise i-viscosity encibilikayo, kwandise i-torque, futhi kube nomthelela othile wokudiliza.Ukusetshenziswa kukapharafini kukodwa kukhombisa ukubambezeleka kwepulasitiki, i-torque encishisiwe, futhi akukho mphumela wokudiliza.Lapho i-calcium stearate ne-parafini wax (i-polyethylene wax) ixubene ngesilinganiso esithile, ibonisa umphumela omuhle, futhi inani le-torque lezinto lingancishiswa kakhulu.Lokhu kungenxa yokuthi upharafini ungena kuma-molecule e-calcium stearate, uqinise ukuthambisa, ubonise umphumela oqinile we-synergistic, futhi uthuthukise ukuhlakazwa kwe-lubricant.

(2) I-Stearic acid – Upharafini (i-polyethylene wax) uhlelo lokuthambisa
Umshini uyafana naleyo ye-calcium stearate - Upharafini (i-polyethylene wax) uhlelo, olungathuthukisa ukuzinza kokushisa kwefomula, ukunciphisa ukuncipha, ukuthuthukisa uketshezi, futhi kube lula ukudiliza.
(3) I-polyethylene wax ene-oxidized - esters - calcium stearate
Lapho i-polyethylene wax, i-ester ne-calcium stearate isetshenziswa ndawonye, ​​isikhathi seplastiki ngokusobala sinwetshwa ngokwenyuka kwenani le-wax ye-polyethylene, kuyilapho lapho i-polyethylene ene-oxidized wax, i-parafini wax, i-ester ne-calcium stearate isetshenziswa ndawonye, ​​​​isikhathi se-plasticizing siyanda kuqala futhi bese yehla ngokunyuka kwenani le-wax ye-polyethylene ene-oxidized, okubonisa umphumela osobala we-synergistic.
Sengiphetha, lapho ufunda ifomula yephrofayela ye-PVC, kubalulekile ukuqonda hhayi kuphela izici nemisebenzi ye-lubricant ngayinye, kodwa futhi nomphumela we-synergistic phakathi kwabo.Ngaphezu kwalokho, ifomula yephrofayili ye-PVC idinga ukulungiswa futhi ishintshwe ngokuya ngomehluko wemishini yokucubungula nokubunjwa.
