Redispersible poda VAE
Re-dispersible polymer poda zvigadzirwa chinhu chakakosha hunyanzvi munzvimbo yekuvaka uye maindasitiri ekushandisa, achipa mhinduro dzakasiyana siyana nekuda kwezvakasiyana zvivakwa uye kugona. Mapoda aya anonyanya kunyungudika mumvura uye anogona kuiswa mumhando dzakasiyana-siyana zvichienderana nemakemikari adzo, kusanganisira ethylene/vinyl acetate copolymers, vinyl acetate/ethylene terephthalate copolymers, uye acrylic acid copolymers. Mhando yega yega yecopolymer inopa hunhu hwakasiyana hunoenderana nehuwandu hwekushandisa mumaindasitiri akasiyana, kubva kune zvinonamira kusvika kune machira, nekudaro kuwedzera mukana wekushandisa mune zvakasiyana zvekuvaka. Izvi zvakasiyana-siyana zvakakosha mukusangana nekuwedzera kuri kuda kwezvinhu zvepamberi izvo zvinogonesa kuvandudzwa kwekuita uye kusimba mune zvigadzirwa zvemazuva ese.
Maitiro ekugadzira ezve-dispersible polymer poda anosanganisira nzira dzekupfapfaidza-kuomesa, izvo zvinotungamira mukuumbwa kwehupfu hwakatsetseka hunyoro hunobatsira pakubata nekugadzirisa. Zvakakosha, idzi poda dzinodzivirirwa nepolyvinyl doro panguva yekugadzirwa, kuve nechokwadi kuti vanochengetedza kuvimbika kwavo kusvika vagadzirira kuparadzirwa zvakare. Kana idzi poda dzinoparadzirwa patsva dzakasangana nemvura, dzinoratidza kugona kwakasiyana-siyana kukurumidza kudzoka kumvura, zvichiita kuti zvive nyore kushandisa mukushandisa kwakasiyana. Hunhu uhwu hunonyanya kukosha munzvimbo dzinokosha kushanda nesimba, sezvo zvichibvumira makondirakiti nenyanzvi dzeindasitiri kushanda zvisina musono nezvinhu pasina nguva yekumirira yekusanganisa kana activation.
Iwo mashandisirwo akasiyana-siyana e-re-dispersible polymer powders anowedzerwazve nehukuru hwavo hwekuita hunhu. Yavo yakakwirira yekunamira kugona inoita kuti ive yakakodzera kushandiswa mukunamira kwekuvaka, matani anonamira, uye akasiyana ekubatanidza maejenti, achipa yakasimba, yakavimbika kubatana mune zvekuvaka. Pamusoro pezvo, iyo yekuzvarwa yemvura kuramba kweaya mapolymer poda inopa dziviriro kubva mukunyorova kupinza, izvo zvakakosha pakuchengetedza hupenyu hurefu uye kusimba kwezvivakwa. Iyo yekupisa yekudzivirira zvivakwa inobatsirawo mukushanda kwesimba muzvivakwa, zvichiita kuti ive sarudzo yakakurumbira pakati pevagadziri uye mainjiniya anotarisana neyakagadziriswa dhizaini mhinduro. Sezvo maindasitiri arikuramba achitsvaga zvinhu zvitsva zvekuvandudza kunaka kwechigadzirwa uye kuita, basa reaparadzikazve polima hupfu hunogona kukura zvakanyanya, zvichiratidza kukosha kwazvo mune zvese zvazvino uye mune ramangwana mashandisiro.
