Photo ID dosage (g / cm) dcJ / m) 8o. 8097o. 897.5】 8o. 857.549o. 806.09l2oS58.78 foam. Figure 8,[link widoczny dla zalogowanych],9,1 O ~ CaCO increase the amount of embedded views were from the 6 to 8, cell structure becomes better 8 phr,[link widoczny dla zalogowanych], the foam to shape over the previous two regular, uniform size. However, another large amount, (Fig. 11,12) become regular foam, but the uniformity was still good. Look at the corresponding physical properties of the situation. Impact strength with caC0: to increase the amount of the increase; CaCO; the density of foam products have an impact, but more volatile, and later Figure 8 (cacoa6 Forest) Figure 9 (cac 【137) 9 4 poly PCE 1996 prince Yu 1.0 (C.aco8 were field 12 {() | l. poison sacs nearly snapped. This is because Fu c0, promoting the formation of foam to avoid permanent temple used in the experiment is _ Tongue of c at c0. it nine and a good surface to make foam evenly divided just to improve the village shrews Fei impact strength. but too much caco,[link widoczny dla zalogowanych],, strong engine of foam that most of Gou,[link widoczny dla zalogowanych], and even this only from the saturated pore structure l point of view, CaCO. 8 units were more appropriate. 102.3 processing modifier (ACR401) experimental conditions: the amount of change table 6ACR hit 34567 ACR dosage poison (i, m) O.58O.68O.82O.78O.82 ÷ ■ hit apartment cU, m 3.493.727.254.964.79 prince Yu No. 131415ACR PVC resin added to improve melt strength, so that the foaming process, foam walls to withstand the pressure of gas bubbles A, not ruptured large hole. From the figure, see, ACR with 3 phr, more foam and large, this shows that small can not Longzhu bubbles melt strength. small foam bubbles break through the wall of the hole formed by addition of 4 too copies, the big hole reduced, indicating that the role of ACR for PVC modified to increase the melt,[link widoczny dla zalogowanych], but were added to 7 when the figure foam Figure 13ACR3 fishing) prince Yu 14 (ACR4 copies) 4 / PVC 1996 is Kids in 15tAcR7 copies) 2.4 Conclusion (1) stability system, the role of the AC's comprehensive platform, the stability of dosage adjustments to help AC foaming performance improvements. (2) ACR increase the amount of help to form a stable foam structure. (3) the role of small nuclear CaCO successful, can improve the cell structure.
