2. Tsib Txheej Txheem Xaiv Tsa
① Carrier Resin Compatibility
Homopolymer PP puag → Siv homopolymer PP cab kuj masterbatch
Copolymer PP puag → Siv copolymer PP cab kuj masterbatch
Cov khoom siv tsis sib xws ua rau muaj qhov tsis xws luag, xim xim, thiab txo cov khoom siv kho tshuab
② Melt Flow Index (MFI) Matching
MFI ntawm masterbatch yuav tsum ntau dua los yog sib npaug rau hauv paus cob MFI, los yog nyob rau hauv ± 5 g / 10min
Txhaj tshuaj molding: puag resin MFI 10 ~ 30, masterbatch MFI Ntau dua lossis sib npaug rau 20 pom zoo
Fiber spinning: puag ncig MFI 25 ~ 40, masterbatch MFI Ntau dua lossis sib npaug rau 35 pom zoo
③ Pigment Thaum tshav kub kub Resistance
PP ua haujlwm kub: 200 ~ 260℃- pigments yuav tsum nyob ruaj khov
Organic pigments: xaiv cov qib uas muaj cua sov ua haujlwm siab dua lossis sib npaug ntawm 260℃(xws li PR 254, PB 15: 3)
Zam tsis txhob qis- cua sov-kuj azo pigments - nquag hloov xim lossis los ntshav
④ Dispersion Quality
Thov Lim Siab Tus Nqi (DF Tus Nqi) cov ntawv ceeb toom los ntawm cov neeg muag khoom
Qib fiber ntau: DF Tsawg dua lossis sib npaug ntawm 0.3 MPa·cm² / g
Qib zaj duab xis / txhaj tshuaj: DF Tsawg dua lossis sib npaug ntawm 0.6 MPa·cm² / g
⑤ Migration Resistance & Huab cua ceev
Lub teeb- cov khoom xim muaj xim yuav tsum tau kuaj kev tsiv teb tsaws (kev sib cuag thiab hnyav tsiv teb tsaws)
Cov khoom siv sab nraum zoov: huab cua ceev ntau dua lossis sib npaug rau Qib 4 (ib ISO 105-B02)
Kev sib cuag zaub mov: daim ntawv pov thawj kev ua raws cai (FDA, EFSA, GB 9685)

4. Cov lus nug uas nquag nug
Q: Xim me ntsis ntawm kev txhaj tshuaj molded qhov chaw. Ua rau?
Feem ntau tsis zoo masterbatch dispersion. Kev daws: ① Ua kom rov qab siab (5 ~ 10 MPa); ② tsa qhov kub thiab txias los ntawm 10 ~ 15 degree; ③ Hloov mus rau masterbatch nrog kev ua haujlwm zoo dua.
Q: Cov xim tseem ceeb sib txawv ntawm cov khoom siv. Yuav tswj li cas?
Thov batch-los ntawm-batch xim txawv daim ntawv qhia (ΔE tus nqi). Kev lees paub tus qauv: ΔE Tsawg dua lossis sib npaug rau 1.0. Saib xyuas tus neeg xa khoom zoo ib yam, qauv, thiab kev yuav khoom batch.
Q: Cov khoom ua nkig tom qab ntxiv masterbatch. Vim li cas?
Tej yam ua tau: ① Cov khoom thauj khoom tsis sib xws; ② Kev thauj khoom ntau dhau; ③ Cov tshuaj dispersants tsis sib xws lossis siv quav ciab. Txo kev thauj khoom thiab hloov mus rau cov cab kuj sib xws.
Q: Dawb PP khoom tig daj. Ua rau?
① TiO₂ qib tsis raug - siv Rutile-hom (R- qib) TiO₂; ② Ua haujlwm kub dhau ua rau PP thermal degradation; ③ Fluorescent whitening agents uas tsis muaj cua sov tsis txaus.
