HPMC E 50
I-EipponCellHPMC E 50 I-Hydroxypropyl methylcellulose luhlobo olubalaseleyo lwe-dispersant esetyenziswa kwishishini le-polyvinyl chloride (PVC).Isetyenziswa ngexesha lokunqunyanyiswa kwepolymerization yevinyl chloride ukuze kuncitshiswe ngokufanelekileyo ukunyanzeliswa kobuso phakathi kwevinyl chloride monomer (VCM) kunye namanzi.Oku kuncipha koxinzelelo kunceda ngokufana nangokuzinzileyo ukusasaza i-VCM ngaphakathi kwendawo yamanzi.Ukongezelela, inceda ekukhuseleni ukudibanisa kwamaconsi e-VCM ekuqaleni kwenkqubo ye-polymerization kwaye inqanda ukudibanisa phakathi kweengqungquthela ze-polymer kwinqanaba eliphakathi kunye nelomva.Kwinkqubo yokumiswa kwe-polymerization, i-EipponCellHPMC E 50 i-Hydroxypropyl methylcellulose isebenza ngeenjongo ezimbini zokusabalalisa kunye nokukhusela ukuzinza.

HPMC F 50
I-EipponCellHPMC F 50, i-hydroxypropyl methyl cellulose, isebenza njenge-dispersant kwishishini le-PVC.Kwinkqubo yokumiswa kwepolymerization ye-vinyl chloride, i-dispersants esetyenziswa ngokuqhelekileyo ibandakanya iikhompawundi ze-polymer ezifana ne-polyvinyl alcohol kunye ne-cellulose ether.Xa ziphantsi kokuvuselela, ziququzelela ukubunjwa kwamaconsi kunye nobukhulu obufanelekileyo.Esi sikhundla kubhekiselwa kuso njengesakhono sokusasaza se-disperant.Ukongeza, i-disperant ifakwe kumphezulu we-vinyl chloride monomer droplets, yenza umaleko okhuselayo okhusela ukuhlanganisana kwe-droplet kunye nokuzinzisa.Esi siphumo saziwa njengesakhono sokugcina i-colloid se-dispersant.
