HPMC E 50
EipponCellHPMC E 50 Hydroxypropyl methylcellulose yog ib hom tseem ceeb ntawm dispersant siv hauv kev lag luam polyvinyl chloride (PVC).Nws yog siv thaum lub sij hawm ncua kev kawm ntawv polymerization ntawm vinyl chloride kom zoo txo qhov kev sib tshuam ntawm vinyl chloride monomer (VCM) thiab dej.Qhov kev txo qis hauv qhov nro no yuav pab ua kom sib npaug thiab ruaj khov ntawm VCM hauv cov dej nruab nrab.Tsis tas li ntawd, nws pab tiv thaiv kev sib koom ua ke ntawm VCM cov tee dej thaum pib ntawm cov txheej txheem polymerization thiab inhibits coalescence ntawm polymer hais nyob rau hauv nruab nrab thiab tom qab theem.Nyob rau hauv lub ncua kev kawm ntawv polymerization system, EipponCellHPMC E 50 Hydroxypropyl methylcellulose pab ib tug dual lub hom phiaj ntawm dispersion thiab stability tiv thaiv.

HPMC F 50
EipponCellHPMC F 50, hydroxypropyl methyl cellulose, ua haujlwm raws li cov khoom tawg hauv PVC kev lag luam.Nyob rau hauv cov txheej txheem ncua kev kawm ntawv polymerization ntawm vinyl chloride, feem ntau siv dispersants muaj xws li polymer tebchaw xws li polyvinyl cawv thiab cellulose ether.Thaum raug nplawm, lawv pab txhawb kev tsim cov tee dej nrog qhov ntau thiab tsawg.Lub peev xwm no yog hu ua lub peev xwm ntawm cov dispersing.Tsis tas li ntawd, cov dispersant yog adsorbed rau saum npoo ntawm vinyl chloride monomer droplets, tsim ib txheej tiv thaiv uas tiv thaiv cov tee aggregation thiab stabilizes lawv.Cov nyhuv no yog hu ua colloid retention peev xwm ntawm dispersant.
