Redispersible latex powder (RDP) inoshandiswa zvakasiyana-siyana uye yakakosha yekuwedzera mumatope ekugadzira iyo inopa mabhenefiti akasiyana siyana anovandudza mashandiro uye kusimba kwedhaka-based materials.Doka musanganiswa wesimende, jecha nemvura zvinowanzoshandiswa mukuvaka kusunga masonry units uye kupa hunhu hwakasiyana kune chivakwa.Iko kuiswa kwe redispersible latex powder mumatope ekugadzirisa kuri kuwedzera kukurumbira nekuda kwekuita kwayo kwakanaka pane zvakasiyana-siyana.
1. Wedzera kunamatira uye kuita kwekubatana:
Kuwedzerwa kwe redispersible latex poda inovandudza zvakanyanya kunamatira kwedhaka kune akasiyana substrates.Uku kunamatira kwakasimudzirwa kwakakosha kuve nechokwadi chekubatana kwakasimba uye kunogara kwenguva refu pakati pedhaka uye masonry unit.Iwo mapolymer particles anoumba firimu rinoshanduka asi rakaomarara kana rakaiswa hydrated, richikurudzira kusangana kuri nani neiyo substrate uye kuderedza njodzi yekubvisa kana delamination.
2. Kuvandudza kuchinjika uye kusagadzikana kwekutsemuka:
Redispersible latex poda inopa kuchinjika kune iyo dhaka matrix, ichiita kuti irambe yakasimba pakutsemuka.Iyo firimu repolymer rakagadzirwa panguva yehydration rinoita sebhiriji rakatsemuka, richibvumira dhaka kuti rigadzirise kufamba kudiki uye kushushikana pasina kukanganisa kutendeseka kwayo.Uku kuchinjika kunonyanya kubatsira munzvimbo dzinowanzo chinja tembiricha uye seismic chiitiko.
3. Kuchengeta mvura uye kushanda zvakanaka:
Iyo yekuchengeta mvura zvivakwa zve redispersible latex poda inobatsira kuwedzera kushanda kwedhaka.Iwo mapolymer particles anonyatso kuchengetedza mamorekuru emvura, kudzivirira kukurumidza kurasikirwa nekunyorova uye kuwedzera nguva yekushandisa.Izvi zvinonyanya kubatsira mumamiriro ekupisa uye akaoma sezvo zvichipa vashandi vekuvaka nguva yakawanda yekubata uye kugadzira dhaka risati ragadzika.
4. Kuwedzera kusimba uye kuramba mamiriro ekunze:
Madhaka ane disperible polymer poda anoratidza kusimba kwakagadziridzwa pasi pemamiriro ekunze asina kunaka.Iyo polymer membrane inoshanda sechidziviriro chinodzivirira, ichideredza kupinda kwemvura uye hukasha hwezvakatipoteredza zvinhu mumatope matrix.Uku kusimbaradzwa kwemamiriro ekunze uku kunoita kuti chivakwa chirambe chakasimba uye kunoderedza zvinodiwa pakugadzirisa.
5. Deredza kupera:
Shrinkage idambudziko rakajairika nedhaka rechinyakare uye rinogona kutungamira mukugadzirwa kwemakatsemuka nekufamba kwenguva.Redispersible latex poda inobatsira kuderedza shrinkage nekusimudzira zvisungo zvekubatanidza zvedhaka matrix.Iyo inochinjika yepolymer firimu inoderedza kushushikana kwemukati, ichideredza mukana wekupwanya kutsemuka uye kuvandudza kushanda kwese kwedhaka.
6. Kuvandudza kuomesa-kunyungudika kwechando:
Madhaka ane redispersible latex poda anoratidza anokwidziridzwa kuramba kutonhora-kunyungudika kutenderera.Iyo polymer membrane inopa chidziviriro chekudzivirira chinobatsira kudzivirira mvura kuti isapinde mumatope.Izvi zvakakosha mumamiriro ekunze anotonhora, uko kuwedzera nekumisikidzwa kwemvura panguva yechando nekunyunguduka kunogona kukonzera kuparara kwedhaka rechinyakare.
7. Kuenderana nemhando dzakasiyana dzekuwedzera:
Redispersible latex powders inowirirana nehuwandu hwakawanda hwezvinowedzera, zvichibvumira kugadzirwa kwemadhaka ane hunyanzvi ane zvimiro.Izvi zvakasiyana-siyana zvinogonesa kugadzirwa kwematokari akakodzera kune chaiwo maapplication, senge madhiri ekumisikidza, madhiri ekuzvimisa kana madhaka akagadzirirwa kushandiswa mune chaiwo mamiriro ezvakatipoteredza.
8. Green Building uye Sustainable Construction:
Iko kushandiswa kweredispersible latex poda mumatope kunopindirana nemaitiro egirinhi ekuvaka uye kuvaka kwakasimba.Iko kuita kwakagadziridzwa uye kusimba kwemapolymer-akagadziridzwa madhaka anobatsira kuwedzera hupenyu hwesevhisi yezvivakwa uye kuderedza kudiwa kwekugadzikiswa nekutsiviwa.Pamusoro pezvo, mamwe anodhindwazve latex poda anogadzirwa achishandisa maitiro ane hushamwari nharaunda uye anogona kunge aine zvakadzokororwa zvemukati.
9. Wedzera kunaka kukwezva:
Iyo yakagadziridzwa kushanda uye kubatanidza zvivakwa zvepolymer-yakagadziridzwa madhaka anobatsira kuwana yakapfava, inowirirana kupera.Izvi zvinonyanya kukosha mumashandisirwo apo kutaridzika kwekunaka kwepasi pevhu kuri kutariswa kwakakosha, senge ruzivo rwekuvaka kana zvidhinha zvakafumurwa.
10. Mhinduro inodhura:
Nepo redispersible latex powders inogona kuwedzera kumutengo wekutanga wekugadzira dhaka, zvikomborero zvenguva refu mukuderedzwa kwekugadzirisa, hupenyu hurefu hwebasa uye kushanda kwakagadziridzwa zvinowanzopfuura mari yekutanga.Iko kudhura-kushanda kwepolymer-yakagadziridzwa dhaka inoita kuti ive inoyevedza sarudzo kune akasiyana mapurojekiti ekuvaka.
Iko kubatanidzwa kwemapolymer anorasika muE poda mumatope ekugadzira kunopa akawanda mabhenefiti ayo anokanganisa mashandiro, kusimba uye huwandu hwese hwezvinhu zvekuvaka.Kubva pakunamira kwakagadziridzwa uye kuchinjika kusvika pakusimudzirwa kwemamiriro ekunze uye nekudzikira shrinkage, mabhenefiti aya anoita kuti madhaka akagadziridzwa epolymer ave sarudzo yakakosha kune dzakasiyana siyana dzekushandisa muindasitiri yekuvaka.Sezvo tekinoroji ichiramba ichifambira mberi, humwe hutsva mukugadzirisazve latex poda maumbirwo anogona kufambisa kuenderera mberi kwekuvandudzwa kwezvinhu zvevhu kuti zvipe mhinduro dzakasimba uye dzepamusoro-soro dzenzvimbo yakavakirwa.
