Upfu hwelatex hunonyungudika, hunozivikanwawo seupfu hwepolymer hunonyungudika (RDP), ihupfu hwepolymer hunogadzirwa ne latex inopfapfaidza nemvura. Hunowanzo shandiswa sechinhu chinowedzera muzvinhu zvakasiyana-siyana zvekuvaka, kusanganisira dhaka. Kuwedzera upfu hwelatex hunonyungudika mumadhaka kunopa mabhenefiti akasiyana-siyana, anosanganisira kunamira zviri nani, kuchinjika, kuramba mvura uye kushanda zvakanaka.
A. Hunhu hweupfu hwelatex hunonyungudika zvakare:
1. Kuumbwa kwePolymer:
Upfu hwelatex hunodzokororwa hunowanzo umbwa nemapolymer akasiyana-siyana, akadai sevinyl acetate-ethylene (VAE), vinyl acetate-ethylene carbonate (VeoVa), nezvimwewo. Mapolymer aya anobatsira pakukwanisa kweupfu kupararira mumvura.
2. Saizi yezvikamu:
Hukuru hwehupfu hwelatex hunonyungudika hunokosha pakuparara kwayo uye kushanda kwayo mukushandiswa kwakasiyana-siyana. Hupfu hwakakamurwa zvakanaka hunovimbisa kupararira nyore nyore mumvura kuti hugadzire emulsions dzakagadzikana.
3. Kugona kupararirazve:
Chimwe chezvinhu zvikuru zvine chekuita nehupfu uhwu ndechekuti hunogona kunyungudika zvakare. Kana hukasanganiswa nemvura, hunogadzira emulsion yakasimba yakafanana neyakagadzirwa ne latex, zvichipa mabhenefiti e latex yemvura muchimiro che upfu.
B. Basa reupfu hwelatex hunonyungudika mudura:
1. Kuvandudza kunamira:
Kuwedzerwa kwehupfu hwelatex hunopararira mumatura kunowedzera kunamira kune zvakasiyana-siyana zvepasi, kusanganisira kongiri, masonry uye mataira eceramic. Kunamira uku kuri nani kunobatsira kuvandudza kusimba kwese uye kugara kwenguva refu kwetura.
2. Wedzera kuchinjika:
Matope akagadziriswa neupfu hwelatex hunonyungudika zvakare anoratidza kuchinjika kwakanyanya. Izvi zvinobatsira zvikuru mumamiriro ezvinhu apo substrate inogona kusangana nekufamba kudiki kana kuwedzera kupisa uye kudzikira.
3. Isingapindi mvura:
Upfu hwelatex hunonyungudika hunoita kuti dhaka risanyungudike. Izvi zvakakosha kana dhaka racho rikasangana nemvura kana hunyoro, senge munzvimbo dzinoshandiswa kunze kana munzvimbo dzine hunyoro.
4. Deredza kutsemuka:
Kuchinjika kunoitwa nehupfu hwelatex hunonyungudika kunobatsira kuderedza mukana wekutsemuka kwedhaka. Izvi zvakakosha zvikuru kana zvidimbu zvingakanganisa kunaka kwechimiro.
5. Kugona kugadziriswa kwakawedzerwa:
Matope ane upfu hwelatex hunonyungudika anowanzo ratidza kushanda kwakawedzerwa, zvichiita kuti zvive nyore kubata nekugadzira. Izvi zvinogona kubatsira panguva yekuvaka.
6. Kuenderana nezvimwe zvinowedzera:
Upfu hwelatex hunonyungudika hunoenderana nezvimwe zvinhu zvinoshandiswa mukugadzira simbi. Kuchinja-chinja uku kunoita kuti mashandiro esimbi aenderane nezvinodiwa pabasa.
C. Mabhenefiti ekushandisa upfu hwelatex hunonyungudika mudura:
1. Kuchinja-chinja:
Upfu hwelatex hunonyungudika hunoshandiswa zvakanyanya uye hunogona kushandiswa mumhando dzakasiyana dzemamortar, kusanganisira mamortar e thinset, mamortar ekugadzirisa, uye mamortar asingapindi mvura.
2. Wedzera kugara kwenguva refu:
Matombo akagadziriswa anopa kugara kwenguva refu uye akakodzera kushandiswa kwenguva yakareba uko kwakakosha kuti agare kwenguva refu.
3. Kushanda kwakagadzikana:
Maitiro ekugadzira upfu hwelatex hunonyungudika anodzokororwa anoita kuti pave nekushanda kwakasimba, zvichikonzera mhedzisiro inofungidzirwa mukushandiswa kwemortar.
4. Kubudirira kwemutengo:
Kunyange hazvo mutengo wekutanga weupfu hwelatex hunonyungudika hungave hwakakwira kupfuura zvinowedzerwa zvechinyakare, hunhu hwakawedzerwa hwainoisa mudura hunogona kutungamira mukuchengetedza mari kwenguva refu nekuderedza kudiwa kwekugadzirisa nekugadzirisa.
5. Kufunga nezvezvakatipoteredza:
Upfu hwelatex hunonyungudika hunobva mumvura hune hushamwari kune zvakatipoteredza kupfuura dzimwe nzira dzinoshandiswa muzvinhu zvinonyungudutsa. Hunobatsira mukuvaka kwakasimba.
Upfu hwelatex hunosanganiswazve chinhu chinobatsira zvikuru mukugadzirwa kwemortar, zvichipa mabhenefiti akasiyana-siyana akadai sekuvandudza kunamira, kuchinjika, kuramba mvura uye kudzikira kwekutsemuka. Kushanda kwayo kwakasiyana-siyana uye kuenderana kwayo nezvimwe zvinowedzera kunoita kuti ive sarudzo yekutanga kune akasiyana mashandisirwo ekuvaka. Nekuvandudza hunhu hwemortar, upfu hwelatex hunosanganiswa hunobatsira kuvandudza kugara kwenguva refu uye kushanda kwezvikamu zvekuvaka, zvichiita kuti ive chishandiso chinokosha mumabasa ekuvaka emazuva ano.
