1. Cov roj hmab ntuj
Ntuj roj hmab yog ib qho yooj yim kom tau plasticity. Cov viscosity tsis tu ncua thiab cov viscosity tsawg tus qauv maleic roj hmab muaj qis qis pib viscosity thiab feem ntau tsis tas yuav tsum tau plasticated. Yog tias Mooney viscosity ntawm lwm hom txheej txheem adhesives tshaj 60, lawv tseem yuav tsum tau molded. Thaum siv cov khoom sib xyaw ua ke rau molding, lub sijhawm yog kwv yees li 3-5 feeb thaum qhov kub siab tshaj 120 ℃. Thaum ntxiv plasticizers lossis plasticizers, nws tuaj yeem txo lub sijhawm plasticizing thiab txhim kho cov nyhuv plasticizing.
2. Styrene-butadiene
Feem ntau hais lus, Mooney viscosity ntawm Styrene-butadiene feem ntau yog nyob nruab nrab ntawm 35-60. Yog li ntawd, Styrene-butadiene kuj xav tau tsis muaj plasticizing. Tab sis qhov tseeb, tom qab plasticizing, dispersibility ntawm compounding tus neeg sawv cev tuaj yeem txhim kho, uas pab txhim kho cov khoom zoo. Tshwj xeeb tshaj yog rau cov khoom siv roj hmab, Styrene-butadiene yog ib qho yooj yim rau ua npuas ncauj tom qab plasticating, thiab cov npuas loj yog uniform.
3. Polybutadiene
Polybutadiene muaj cov khoom txias txias thiab tsis yooj yim los txhim kho cov nyhuv plasticizing. Tam sim no, Mooney viscosity ntawm feem ntau siv Polybutadiene tau raug tswj nyob rau hauv ib qho chaw tsim nyog thaum lub sij hawm polymerization, yog li nws tuaj yeem sib xyaw ncaj qha yam tsis muaj plasticizing.
4. Neoprene
Neoprene feem ntau tsis tas yuav tsum tau plasticized, tab sis vim nws lub siab tawv, nws muaj txiaj ntsig zoo rau kev ua haujlwm. Lub nyias dhau qhov kub yog feem ntau 30 ℃ -40 ℃, uas yooj yim rau lo rau yob yog tias nws siab dhau.
5. Ethylene propylene roj hmab
Vim lub saturated qauv ntawm cov saw tseem ceeb ntawm Ethylene propylene roj hmab, nws yog ib qho nyuaj ua rau molecular cracking los ntawm plasticating. Yog li ntawd, nws yog ib qho tsim nyog los ua ke nws kom muaj qhov haum Mooney viscosity yam tsis tas yuav tsum tau molding.
6. Butyl roj hmab
Butyl roj hmab muaj cov qauv tshuaj ruaj khov thiab muag muag, qhov hnyav molecular me me thiab loj fluidity, yog li cov khoom siv plasticizing tsis zoo. Butyl roj hmab nrog qis Mooney viscosity tuaj yeem sib xyaw ncaj qha yam tsis muaj plasticizing.
7. Nitrile roj hmab
Nitrile roj hmab muaj me me plasticity, siab toughness thiab loj thaum tshav kub kub tsim thaum plasticating. Yog li ntawd, tsis tshua muaj kub, tsis muaj peev xwm thiab segmented plasticating feem ntau yog siv nyob rau hauv qhib zeb kom ua tau zoo. Nitrile roj hmab yuav tsum tsis txhob muab plasticated nyob rau hauv lub tov khoom. Raws li cov roj hmab muag Nitrile muaj qee yam plasticity, nws tuaj yeem sib xyaw ncaj qha yam tsis muaj cov yas refining.
