Redispersible polymer poda (RDP) yedhaka simende

Redispersible polymer poda (RDP) ivhu rinonyungudika nemvura rinogona kushandiswa kuvandudza zvinhu zvedhaka nesimende.RDP inogadzirwa ne polymerizing vinyl acetate uye ethylene mune aqueous emulsion.Iyo yakaguma emulsion yakabva yapfapfaidzwa yakaomeswa kuita hupfu hunoyerera mahara.

RDP inoshandiswa mumhando dzakasiyana dzedhaka uye simende zvigadzirwa zvinosanganisira:

tile adhesive

self leveling mortar

Putty powder

crack filler

Insulation mortar

Cement-based plaster

Cementitious Coatings

RDP inovandudza mashandiro ematope nemasimende ne:

kuwedzera kuchengetwa kwemvura

Vandudza kushanda

kuwedzera kusimba simba

kuwedzera simba rekukotama

kuderedza shrinkage

kuwedzera kudzivirira kwemvura

kuwedzera moto kuramba

Maitiro ekugadzira eRDP ndeaya anotevera:

Vinyl acetate uye ethylene akaiswa polymer mune aqueous emulsion.

Iyo emulsion inopfapfaidzwa yakaomeswa kuita hupfu hunoyerera mahara.

Hupfu hunobva hwaputirwa uye hwotumirwa kumutengi.

Heano zvimwe zvakakosha zvinokanganisa RDP mhando:

Mhando yepolymer inoshandiswa

polymer molecular uremu

polymer concentration

Hupfu particle size

kuvapo kwetsvina

RDP chigadzirwa chakasiyana-siyana chinogona kushandiswa kuvandudza mashandiro emhando dzakasiyana siyana dzedhaka uye simende zvigadzirwa.Nekunzwisisa maitiro ekugadzira uye zvinhu zvakakosha zvinokanganisa kunaka, vagadziri vanogona kugadzira maRDP anosangana nezvinodiwa nevatengi.

Heano mamwe mabhenefiti ekushandisa RDP mudhaka uye simende zvigadzirwa:

RDP inobatsira kuderedza huwandu hwemvura inodiwa mudhaka uye simende misanganiswa.Izvi zvinogona kutungamirira kukuchengetedza mari uye zvikomborero zvakatipoteredza.

RDP inobatsira kuvandudza kushanda kwedhaka uye simende musanganiswa.Izvi zvinogona kuita kuti kushandisa chigadzirwa kuve nyore uye kunogona kuderedza njodzi yekukanganisa.

RDP inobatsira kuwedzera kusimba uye kusimba kwedhaka uye simende zvigadzirwa.Izvi zvinowedzera hupenyu hwechigadzirwa uye zvinoderedza kudiwa kwekugadzirisa.

Pakazere, RDP chishandiso chakakosha chinogona kushandiswa kuvandudza mashandiro edhaka uye simende zvigadzirwa.Nekunzwisisa mabhenefiti eRDP uye zvinhu zvinokanganisa hunhu hwayo, vagadziri vanogona kuita sarudzo dzine ruzivo nezve mashandisiro echigadzirwa kuvandudza zvigadzirwa nemaitiro avo.
