Muhurongwa hwemazuva ano hwezvinhu zvekuvaka, putty powder inoshanda sechinhu chakakosha pakuyera madziro uye kupedzisa pamusoro. Kushanda kwayo kunokanganisa zvakananga kunaka uye kugara kwenguva refu kwependi kana kupedzisa kunotevera. Kusapinda mumvura chiratidzo chikuru chehunhu hweputty. Putty yechinyakare inowanzo shandiswa pazvinhu zvisingasanganisike (senge lime lime, double fly ash, uye simende). Zvisinei, nekuda kwekuoma kwayo uye kusanamatira zvakanaka, inoputsika nyore nyore kana yasangana nemvura, zvichiita kuti zviome kusangana nezvinodiwa zvekushandisa kwenguva refu pamadziro emukati nekunze. Nekushandisaupfu hwepolymer hunonyungudika (RDP), kushanda kwese kweputty, kunyanya kudzivirira kwayo mvura, kwavandudzika zvikuru.
1. Hunhu Hwekutanga hweRDP
RDP imulsion yakaomeswa nespray inoshandurwa kuita upfu hwakasimba hunonyungudika. Kana yasangana nemvura, inosanganisa zvakare uye inodzoreredza hunhu hwepakutanga hwemulsion. Inonyanya kugadzirwa nepolymer resin ine mamorekuru akawanda, colloid inodzivirira, uye zvinowedzerwa. Nekuda kwehunhu hwayo hwakanaka hwekugadzira firimu, kuchinjika, uye kunamira, inoshandiswa zvakanyanya mukuvaka zvinhu zvakaita sedry-mix mortar, tile adhesive, uye putty powder.
2. Zvikonzero zvePutty Kusakwanisa Kuramba Mvura
Zvinhu zvisina kugadzirwa zvinopfava: Putty ye lime-lime kana putty ye cement inova nemavanga mushure mekunyorova, zvichikonzera kuti chimiro chisashande zvakanaka uye kupinda kwemvura nyore nyore.
Kusanamatira Zvakakwana: Kubatana pakati peputty nemadziro epasi nependi kwakashata, zvichiita kuti ive nyore kuzvimba nekudonha munzvimbo dzine hunyoro kana dziri pasi pemvura.
Kupinda-pinda kwakanyanya: Upfu hweputty hwechinyakare hune hunhu husina kunaka uye ma capillaries akawanda, zvichiita kuti zvive nyore kuti mvura ipinde uye iite kuti ipwanyike.
Saka, kuvimba chete nezvinobatanidza zvinhu zvisingararami hazvigone kuvimbisa kuti putty icharamba ichidzivirira mvura kwenguva refu. Kugadziriswa nemapolymers akadai seRDP kunodiwa.
3. Maitiro ekuvandudza kweRDP kweKusapindirana kwePutty neMvura
3.1. Mhedzisiro Yekugadzira Mafirimu
Mushure mekunge RDP yapararira mumvura muputty, inoumba firimu repolymer rinoenderera mberi panguva yekuoma, richifukidza zvakaenzana zvidimbu zvisina organic. Izvi zvinoderedza zvakanyanya kupinza kwemukati meputty, nokudaro zvichideredza kupinda kwemvura.
3.2. Kunamira Kwakawedzerwa
Firimu repolymer rinopinda muma micropores e base layer, zvichiita kuti pave ne "physical anchoring + chemical bonding" mbiri. Izvi zvinosimbisa kubatana pakati pe putty ne substrate, zvichidzivirira kuti isadonhe kunyangwe munzvimbo dzine hunyoro.
3.3. Kuchinjika Kwakavandudzwa uye Kuramba Kutsemuka
Putty inowanzotsemuka nekuda kwekuoma kana kuchinja-chinja kwekushisa nehunyoro, uye kuputika kunova nzira huru yekupinda kwehunyoro. RDP inopa kuchinjika kwakanaka uye kuwedzera kweputty, ichibvisa kushushikana uye ichideredza kuumbwa kwemapuranga, zvichiita kuti mvura isarambe ichinaya.
3.4. Kugona Kwakavandudzwa Kwekudzivirira Kupoda
Putty yechinyakare ye lime-lime inopfava nyore kana yaiswa mumvura. Zvisinei, skeleton ye polymer inoumbwa neRDP muputty inowedzera kugadzikana kwechimiro chayo, ichidzivirira hupfu hunokonzerwa nekukukurwa kwemvura.
4. Mhedzisiro yeRDP muPutty Inodzivirira Mvura
Kudzivirira Mvura Kwakavandudzwa Zvikuru: Ongororo dzakaratidza kuti putty ine huwandu hwakakodzera hweRDP inochengetedza kusimba kwepamusoro mushure memaawa makumi maviri nemana yekunyudzwa mumvura, pasina matumbu kana kusvuuka kunoonekwa. Kushanda Kwakavandudzwa: RDP inoita kuti putty irambe yakanyorova uye igare yakachengetwa, zvichiita kuti ishandiswe zviri nyore uye ive nyore kushandisa.
Kushandiswa Kwakakura: Putty yakasanganiswa neRDP haingokodzeri chete munzvimbo dzakaoma dzemukati asiwo munzvimbo dzine hunyoro dzakadai sekicheni, dzimba dzekugezera, nedzimba dzepasi, uye kunyange putty yekunze yemadziro.
Hupenyu Hwenguva Yakareba: Putty isingapindi mvura inodzivirira kukurwa kwehunyoro kwenguva refu, ichisimbisa kugara kwenguva refu kwesystem yekupedzisa madziro uye ichideredza mari yekugadzirisa inotevera.
5. Kurudziro yeRDP Dosage uye Ratio
Chiyero chinokurudzirwa cheRDP mumafomura eputty chinowanzova 3%-5% (zvichienderana nehuremu hweputty powder). Huwandu hwacho hunofanira kugadziriswa zvichienderana nerudzi rweputty, hunhu hwesubstrate, uye nzvimbo yekushandisa:
Putty yemukati memadziro yakajairika: Inenge 3% yakakwana kusangana nezvinodiwa zvekudzivirira mvura;
Putty yekicheni neyekugezera: 4%-5% inokurudzirwa kuwedzera kusimba kwemvura uye kunamira;
Putty yekunze inodzivirira mamiriro ekunze: Chiyero chinogona kuwedzerwa zvakakodzera kuti ive nechokwadi chekuti mvura haikanganisi kudonha kwevhu uye kuchinja-chinja kwekushisa nehunyoro. Zvakakosha kuziva kuti RDP inodhura zvishoma, uye kuwedzera yakawandisa kunogona kukanganisa hupfumi uye kunogona kuderedza kuomarara kweputty. Saka, kugadzirisa kunofanirwa kufungwa nenzira yakaringana yekushanda uye mutengo.
RDPine basa risingatsivike mukuvandudza kuramba mvura kweputty. Nekugadzira firimu, kuwedzera kunamira, uye kuvandudza kuchinjika uye kuramba kutsemuka, RDP inogadzirisa zvinobudirira dambudziko rekuti putty yechinyakare inopwanyika uye inodonha kana yaiswa mumvura. Izvi zvinobvumira putty kuti isangane nezvinodiwa zvekushongedza madziro emukati chete asiwo kuchengetedza kugadzikana munzvimbo dzine hunyoro nedzekunze. Kushandiswa kwakakodzera kweRDP hakungogadzirisi kuramba mvura uye hupenyu hwebasa reputty chete asiwo kunokurudzira kugadzirwa kwezvinhu zvekushongedza zvekuvaka zvinoshanda zvakanyanya uye zvinogara kwenguva refu.
