Redispersible polymer poda (RDP) chiwedzere chakasiyana-siyana chinoshandiswa zvakanyanya mukuvaka nekuvaka zvinhu.Inoita basa rakakosha mukusimudzira kushanda kwezvakasiyana zvigadzirwa nekupa zvakavandudzwa zvivakwa zvakaita sekunamatira, kuchinjika, kuramba kwemvura uye kusimba.Upfu uhu hunonyanya kuyerera hupfu huchena hunoumbwa nepolymer binder, kazhinji kubva pavinyl acetate-ethylene kana mamwe emulsions ecopolymer.
Nhanganyaya kune Redispersible Polymer Powders
Redispersible polymer powders anogadzirwa nekupfapfaidza kuomesa polymer dispersions.Maitiro acho anosanganisira kushandura mvura latex kuita poda inoyerera yakasununguka nekubvisa mvura.Iyo hupfu inoguma inogona kuparadzirwa nyore nyore mumvura kuti iite emulsion yakagadzikana yakafanana neyepakutanga polymer dispersion.Ichi chakasarudzika chivakwa chinoita kuti RDP ive yakakosha yekuwedzera mune akasiyana maapplication.
Zvimiro zveRedispersible Polymer Powders
1. Magadzirirwo emufirimu:
Kana yawedzerwa kumagadzirirwo, RDP inobatsira kuumba inoenderera uye inoshanduka firimu.
Iyo firimu inopa yakanakisa kunamatira kune akasiyana siyana, ichibatsira kuvandudza iyo yakazara simba uye kusimba kwechigadzirwa chekupedzisira.
2. Isingapindi mvura:
Redispersible polymer poda inosimudzira kuramba kwemvura yechinhu, ichiita kuti ive yakakodzera kune ekunze maapplication ayo anoda kuratidzwa nehunyoro.
3. Kuchinjika:
Kuwedzerwa kweRDP kunowedzera kushanduka kwezvinhu, kudzivirira kuputika uye kuve nechokwadi chekugara kwenguva refu pasi pemamiriro ane simba.
4. Kunamatira:
Kuvandudzwa kwekunamatira ndeimwe yemabhenefiti makuru ekushandisa RDP, kusimudzira zvisungo zvakasimba pakati pema substrates akasiyana.
5. Processability:
RDP inopa kushanda kwakanyanya kune kugadzirwa, zvichiita kuti zvive nyore kune vanogadzira uye vavaki kubata nekushandisa izvo zvinhu panguva yekuvaka.
6. Wedzera zvinhu zvemuchina:
Kuwedzeredzwa kweadhispersible polymer poda kunowanzo kuwedzera simba remuchina wezvinhu, nekudaro zvichivandudza kuita kwese.
Zvishandiso zveRedispersible Polymer Powders
1. Tile Adhesives uye Grout:
RDP inowanzoshandiswa mumatairi anonamira kuvandudza kunamatira, kushanduka uye kuramba kwemvura.
Inobatsira kudzivirira kuputika uye inovandudza kusimba kwekuiswa kwako tile.
2. Exterior Insulation uye Finishing Systems (EIFS):
EIFS inobatsira kubva mukuramba kwemvura uye kuchinjika kwakapihwa neRDP, kuve nechokwadi chekuti envelopu yekuvaka inogara kwenguva refu uye inodzivirira mamiriro ekunze.
3.Kuzvimisa-leveling underlayment:
RDP inokwidziridza mashandiro ekuzvigadzika pasi pasi kuti ipe nzvimbo yakatsetseka uye yakasimba kune inotevera kuisirwa pasi.
4. Dope nepurasita:
Madhiri uye mapurasita anoshandisa RDP akavandudza kunamatira, kushanda uye kuramba kune zvakatipoteredza zvinhu, zvichiita kuti ive yakanaka kune dzakasiyana siyana dzekuvaka.
5. Gypsum-based products:
Redispersible polymer poda inowanzowedzerwa kune gypsum-based formulations kuwedzera simba, kunamatira uye kutsemuka kuramba.
6. Waterproof membrane:
Kupokana kwemvura kweRDP kunoita kuti ive chinhu chakakosha chekuvaka ma membranes ekudzivirira mvura.
7. Crack fillers uye majoint compounds:
RDP inobatsira kuvandudza kuchinjika uye kunamatira kweanopwanya mafirita uye majoini makomputa, kuve nechokwadi chekugadzirisa uye kunogara kwenguva refu.
8. Simende zvigadzirwa:
Cement-based products, zvakadai sekugadzirisa dhaka uye grouts, zvinobatsirwa nekuvandudzwa kwekushanda uye kusimba kunopiwa neRDP.
9. Texture coating:
Kusimba uye kuramba kwemamiriro ekunze kwependi yemavara ekunze kunokwidziridzwa kana RDP ichibatanidzwa mukugadzira kwavo.
10. Caulks uye Sealants:
RDP's kuchinjika uye inonamira zvivakwa zvinoita kuti ive yakakosha yekuwedzera mucaulking uye sealant maumbirwo, kuvandudza mashandiro avo nekufamba kwenguva.
Mafungiro Ezvakatipoteredza uye Kudzora
1. Kukanganisa kwezvakatipoteredza:
Redispersible polymer powders anowanzoonekwa seane hushamwari kwezvakatipoteredza nekuti anobatsira kuwedzera hupenyu uye kusimba kwezvinhu, kuderedza kudiwa kwekudzoreredzwa.
2. Regulatory Compliance:
Vagadziri nevashandisi veRDP vanofanirwa kutevedzera mirairo yemuno neyekunze maererano nekushandiswa kwemapolymer muzvinhu zvekuvaka.
mukupedzisa
Redispersible polymer poda akakosha ekuwedzera akawanda muindasitiri yekuvaka.Iyo inosimudzira hunhu hwemhando dzakasiyana-siyana, zvinosanganisira kunamatira, kuchinjika uye kushorwa kwemvura, zvichiita kuti ive chinhu chakakosha mukugadzirwa kweanonamatira, madhaka, machira uye nezvimwe.Iwo akasiyana mashandisirwo eRDP anobatsira kuvaka akasimba, anosimba uye akakwira-kuita zvivakwa.Sezvo tekinoroji iri kuramba ichifambira mberi, basa readhispersible polymer poda rinogona kuwedzera, zvichiwedzera kukanganisa kushandiswa kwezvinhu zvekuvaka uye nzira dzekuvaka.
