HDPE / LDPE blending foaming khoom, nws cov ntaub ntawv raw khoom, thiab suav los ntawm qhov hnyav,
Tag nrho cov naj npawb ntawm HDPE thiab LDPE 100 qhov chaw
Txuas tus neeg sawv cev 0.5 ntu
Ac whipping agent 3-10 feem
Zinc oxide 1-2 ntu
Stearic acid 0.5 feem
Antioxidant 1010 0.1 ntu
Mineral muab tub lim 3-15 ntu,
Qhov twg, qhov hnyav piv ntawm HDPE thiab LDPE yog 10: 90-90: 10,
Nyob rau hauv qhov no, lub melt flow rate (MFR) ntawm HDPE xaiv yog nyob nruab nrab ntawm 3-6g / 10min, thiab melt flow rate (MFR) ntawm LDPE yog nyob nruab nrab ntawm 2-3g / 10min;
Raws li qhov xav tau: kev sib txuas tus neeg sawv cev raug xaiv los ntawm dicumyl peroxide DCP lossis benzoyl peroxide BPO;
Raws li qhov xav tau: cov pob zeb hauv av tau xaiv los ntawm calcium carbonate lossis mica hmoov.
Tam sim no invention kuj muaj ib hom kev npaj ntawm saum toj no-hais HDPE / LDPE blending foaming khoom, pob zeb ua hauj lwm yog:
Los ntawm proportioning ntawm txhua raw khoom,
(1) los ntawm granulation ntawm HDPE thiab LDPE blending extrusion, qhuav, tau txais cov khoom siv hauv paus,
Raws li qhov xav tau: siv ntxaib ntsia hlau extruder, nqa tawm mus rau HDPE thiab LDPE, zoo sib xyaw nyhuv, tuaj yeem extrude tsis tu ncua, cov zis loj heev;
(2) lub hauv paus-cov ntaub ntawv tau txais nyob rau hauv cov kauj ruam (1) yog plasticated nyob rau hauv zeb, plasticates nyob rau hauv cov txheej txheem, nyob rau hauv lub hauv paus-cov ntaub ntawv, ntxiv auxiliary tus neeg sawv cev, tom qab auxiliary neeg sawv cev sib tov nrog rau hauv paus-cov ntaub ntawv, compound ntsiav tshuaj yog muab tshem tawm, flattens thaum kub,
