ACM roj hmab molded khoom
1. Kev Taw Qhia Zej Zog
ACM - ROJ HMAB POLYACRYLIC
TSWV YIM
Polyacrylic elastomers, kuj hu ua ACM rubbers, yog cov khoom cua sawv ntawm cov kab mob acrylic. Cov polymers no feem ntau yog npaj los ntawm emulsion los yog rho tawm polymerization. Lub ntsiab rov ua dua yog cov ethyl thiab butyl acrylate los yog ob qho tib si. Ntau lwm cov monomers tuaj yeem suav nrog uas pub rau ntau qhov kev hloov ntawm cov thermophysical thiab mechanical properties. Ntau heev yog qhov sib ntxiv ntawm 5 feem pua 2-chloroethyl vinyl ether.
Kev sib xyaw ntawm cov phom uas muaj kab xaum tawg nrog cov qhabnias ntawm sab nraud tuaj rau hauv chav kawm ntawm cov polymers uas muaj cov tshuaj tiv thaiv kom sov, oxidation thiab hydraulic roj. ACM's kuj muaj kev tiv thaiv zoo rau ozone, thiab weathering uas yog superior rau cov roj hmab nitrile. Txawm li cas los, dej thiab noo noo tsis yog ploj, raws li yog tsis kam rau acids thiab alkalis. Tsis tas li ntawd, cov kev siv qis dua feem ntau tsuas yog siv li ntawm -10 ° C vim muaj qhov kub txias txias thiab cov txheej txheem txeem kom qis.
Cov kev hloov kho ntau hom copolymer tau raug tsim los txhim kho cov khoom ntawm ACM. Cov kev hloov kho muaj xws li lwm cov pob txha caj qaum thiab kev koom tes ntawm pab pawg neeg sib txuam (1-5%) rau tom qab sib tw.
2. Cov ntawv thov :
ACM elastomers feem ntau yog siv qhov chaw xyaw ua haujlwm kom sov thiab roj yog qhov yuav tsum tau ua. Lawv feem ntau yog ib qho zoo tshaj plaws rau cov cua sov uas tsis tshua muaj siab kub hnyiab xws li fluorocarbon polymers (FKM), silicones (VMQ) thiab fluorosilicones (FVMQ) rau cov ntawv thov kub siab (<150 °="">
Cov kev siv roj muaj xws li cov tsheb thauj khoom xws li cov ntaub ntim thiab hoses uas yuav tsum ua rau cov roj kub, roj thiab ntau lwm cov roj tsheb ntau thiab cov dej hydraulic. ACM elastomer kuj pom muaj nyob hauv kev kub ntxhov vim nws cov kev pabcuam zoo heev. Lwm cov ntawv muaj xws li textiles, adhesives, thiab coatings.
Qhov nruab nrab ntawm kev kub ntxhov siab raug ncua yog -10 ° C mus txog 150 ° C (txog li 175 ° C rau qee lub sijhawm).
