Paura rapa polymer ka taea te whakamarara anōKo ngā hua he paura wairewa-anō, e wehea ana ki ngā copolymers ethylene/vinyl acetate, ngā copolymers vinyl acetate/tertiary ethylene carbonate, ngā copolymers waikawa acrylic, me ētahi atu, me te waipiro polyvinyl hei colloid tiaki. Nā te kaha here teitei me ngā āhuatanga ahurei o ngā paura polymer wairewa.
Mā te tāpiri i te paura pūmua marara ki te moata whakakī hononga ka pai ake tōna piripono me tōna ngāwari.
Me pai te piri o te moata honohono ki te rauemi turanga e piri ai ahakoa he angiangi rawa te paninga. Ko ngā moata sima kāore i whakarerekētia, kāore e pai te piri mena kāore i te rongoatia te turanga i mua.
Mā te tāpiri i te paura rapa ka taea te whakamarara anō ka whakapai ake i te piri. Mā te ātete saponification o te paura rapa ka taea te whakamarara anō ka taea te whakahaere i te nui o te piri o te moata i muri i te pa atu ki te wai me te huka. Ka taea te whiwhi i te polymer ātete-saponification mā te whakakotahi i te vinyl acetate me ētahi atu monomers e tika ana. Mā te whakamahi i te ethylene hei comonomer kore-saponifiable ki te hanga paura rapa ka taea te whakamarara anō kei roto i te ethylene ka taea te whakatutuki i ngā whakaritenga katoa mō ngā paura rapa e pā ana ki te ātete koroheketanga me te ātete hydrolysis.
