Cov Kauj Ruam Ua Haujlwm:
- Ua ntej sib tov tag nrho cov khoom sib npaug.
- Siv lub tshuab extruder twin-screw yaj thiab pelletize, yaj-blend.
- Tswj qhov kub ntawm extrusion ntawm 180–220 ° C.
Cov yam ntxwv:
- Muaj hluav taws kub heev nrog kev thauj khoom tsawg.
- Tej zaum yuav tso tawm cov pa roj lom thaum lub sijhawm hlawv.
- Haum rau cov ntawv thov nrog cov kev cai ib puag ncig qis.
III. Cov Tshuaj PP Masterbatch Uas Tsis Muaj Halogen Uas Tiv Thaiv Tau Hluav Taws
Cov tshuaj retardants uas tsis muaj halogen (piv txwv li, phosphorus-, nitrogen-based, lossis inorganic hydroxides) yog cov phooj ywg zoo rau ib puag ncig tab sis xav tau cov khoom thauj ntau dua.
Piv txwv kev tsim qauv:
- Cov roj hmab nqa khoom (PP): 30–40%
- Cov tshuaj retardant uas muaj phosphorus (piv txwv li, ammonium polyphosphate APP lossis liab phosphorus): 20–30%
- Cov tshuaj retardant uas muaj nitrogen (piv txwv li, melamine cyanurate MCA): 10–15%
- Magnesium hydroxide los yog txhuas hydroxide: 20–30%
- Cov tshuaj yaj tawm (piv txwv li, polyethylene wax): 2–3%
- Cov roj nplua nyeem (piv txwv li, zinc stearate): 1–2%
- Tshuaj tua kab mob (piv txwv li, 1010 lossis 168): 0.5–1%
Cov Kauj Ruam Ua Haujlwm:
- Ua ntej sib tov tag nrho cov khoom sib npaug.
- Siv lub tshuab extruder twin-screw yaj thiab pelletize, yaj-blend.
- Tswj qhov kub ntawm extrusion ntawm 180–210 ° C.
Cov yam ntxwv:
- Eco-friendly, tsis muaj cov pa roj lom thaum lub sijhawm combustion.
- Kev ntxiv ntau ntxiv yuav ua rau cov khoom siv kho tshuab puas tsuaj.
- Haum rau cov ntawv thov nrog cov qauv ib puag ncig nruj.
IV. Cov Kev Xav Tseem Ceeb hauv Kev Tsim Qauv
- Kev xaiv hluav taws kubXaiv cov halogenated lossis halogen-free raws li qhov yuav tsum tau ua kom tsis txhob muaj hluav taws thiab cov cai ib puag ncig.
- Kev sib raug zoo ntawm cov khoom siv thauj khoomYuav tsum sib xws nrog lub hauv paus PP kom tiv thaiv kev tawg.
- Kev tawg tawm: Cov tshuaj dispersants thiab cov roj nplua nyeem ua kom muaj kev faib tawm ntawm cov tshuaj retardants sib npaug.
- Kub ua tiavTsis txhob kub dhau kom tiv thaiv kev lwj.
- Cov khoom siv kho tshuab: Cov khoom siv ntxiv ntau dhau yuav ua rau kev ua haujlwm tsis zoo; xav txog cov tshuaj ua kom tawv (piv txwv li, POE lossis EPDM).
V. Cov Ntawv Thov Ib Txwm Muaj
- Cov tshuaj halogenated masterbatchCov tsev siv hluav taws xob, cov xov hlau/cables.
- Cov tshuaj masterbatch uas tsis muaj halogen: Cov khoom siv sab hauv tsheb, cov ntaub ntawv tsim kho, cov khoom ua si rau menyuam yaus.
VI. Cov Lus Qhia Txog Kev Txhim Kho
- Txhim kho qhov hluav taws kubUa ke ntau yam tshuaj retardants (piv txwv li, phosphorus-nitrogen synergy).
- Txhim kho cov khoom siv kho tshuabNtxiv cov khoom ua kom tawv (piv txwv li, POE/EPDM).
- Txo nqi: Ua kom cov piv ntawm cov tshuaj retardant zoo dua thiab xaiv cov ntaub ntawv uas pheej yig dua.
Los ntawm kev tsim cov qauv tsim thiab kev tsim cov txheej txheem, PP cov tshuaj tua hluav taws masterbatches tuaj yeem ua tau raws li ntau yam kev xav tau ntawm daim ntawv thov.
Vim yog cov kev cai ib puag ncig thiab cov khoom tsis txaus ntawm antimony trioxide, cov neeg siv khoom ntau zuj zus siv cov tshuaj halogen-free phosphorus-nitrogen flame retardants rau PP masterbatches. Piv txwv li,TF-241tuaj yeem siv ncaj qha rau cov khoom PP thiab cov masterbatches, ua tiav cov teebmeem char-forming thiab intumescent yam tsis muaj cov khoom ntxiv. Txhawm rau kom zoo dua cov khoom siv kho tshuab, pom zoo kom siv cov plasticizers thiab cov neeg sawv cev sib txuas kom txaus.
