Khethollo ea li-RDP e ipapisitse le lintlha tse 'maloa, ho kenyelletsa le sebopeho sa lik'hemik'hale, mokhoa oa polymerization, le thepa ea ho qetela ea sehlahisoa. Sehloohong sena, re tla tšohla karohano ea li-RDP ho latela sebopeho sa tsona sa lik'hemik'hale.

1. Vinyl Acetate Ethylene (VAE) RDPs

VAE RDPs ke mofuta o sebelisoang haholo oa li-RDP. Li entsoe ka copolymerizing vinyl acetate (VA) le ethylene (E) ka pel'a li-monomers tse ling tse kang acrylate kapa methacrylate. Likahare tsa VA ho copolymer li fapana lipakeng tsa 30% le 80%, ho latela ts'ebeliso e reriloeng. Li-RDP tsa VAE li tsebahala ka thepa ea tsona e ntle ea sekhomaretsi, ho tenyetseha habonolo, le ho hanyetsa metsi. Li sebelisoa ka tloaelo ho li-adhesives tsa lithaele, lijase tsa skim le li-putty tsa lebota.

2. Acrylic RDPs

Acrylic RDPs li entsoe ka copolymerizing acrylic esters le monomers tse ling tse kang vinyl acetate, ethylene, kapa styrene. Li-ester tsa acrylic tse sebelisoang ho copolymer e ka ba methyl methacrylate (MMA), butyl acrylate (BA), kapa motsoako oa bobeli. Thepa ea li-RDP tsa acrylic e ipapisitse le karo-karolelano ea li-monomers tse sebelisitsoeng ts'ebetsong ea copolymerization. Li-Acrylic RDPs li na le khanyetso e ntle ea boemo ba leholimo, 'me hangata li sebelisoa ka har'a masela a ka ntle, masela a thibelang metsi le lilae tsa samente.

3. Styrene Butadiene (SB) RDPs

SB RDPs li entsoe ka copolymerizing styrene le butadiene ka pel'a monomers tse ling tse kang acrylate kapa methacrylate. Likahare tsa styrene ho copolymer li fapana pakeng tsa 20% le 50%, ho itšetlehile ka kopo e reriloeng. Li-RDP tsa SB li na le thepa e ntle ea sekhomaretsi, 'me hangata li sebelisoa ho likhomaretsi tsa lithaele, seretse le li-grouts.

4. Vinyl Acetate (VA) RDPs

Li-RDP tsa VA li entsoe ka homopolymerizing vinyl acetate monomers. Li na le litaba tse phahameng tsa vinyl acetate, ho tloha ho 90% ho isa ho 100%. Li-RDP tsa VA li na le thepa e ntle ea sekhomaretsi, 'me hangata li sebelisoa ho likhomaretsi tsa lithaele, li-bonding agents, le lirafshoa tsa samente.

5. Ethylene Vinyl Chloride (EVC) RDPs

Li-RDP tsa EVC li entsoe ka copolymerizing ethylene le vinyl chloride ka pel'a li-monomers tse ling tse kang acrylate kapa methacrylate. Likahare tsa vinyl chloride ka har'a copolymer li fapana pakeng tsa 5% le 30%, ho latela ts'ebeliso e reriloeng. Li-RDP tsa EVC li na le ho hanyetsa metsi hantle le ho khomarela hantle ho li-substrates tse fapaneng. Li sebelisoa ka tloaelo ho li-adhesives tsa lithaele, lijase tsa skim le li-putty tsa lebota.

Qetellong, li-RDP ke mofuta oa bohlokoa oa phofo ea copolymer e sebelisoang haholo lits'ebetsong tse fapaneng tsa kaho. Ho hlophisoa ha li-RDP ho ipapisitse le lintlha tse 'maloa, ho kenyeletsoa sebopeho sa lik'hemik'hale, mokhoa oa polymerization, le thepa ea ho qetela ea sehlahisoa. Lik'hemik'hale tsa li-RDP li ka aroloa ho Vinyl Acetate Ethylene (VAE) RDPs, Acrylic RDPs, Styrene Butadiene (SB) RDPs, Vinyl Acetate (VA) RDPs, le Ethylene Vinyl Chloride (EVC) RDPs. Mofuta o mong le o mong oa RDP o na le thepa ea ona e ikhethang e etsang hore e lokele lits'ebetso tse ikhethileng.
