Redispersible Polymer Powder (RDP) inoita basa rakakosha muzvigadzirwa zvemazuva ano zvekuvaka, kunyanya mumakomisheni ekuzvimiririra. Aya makomisheni, akakosha pakugadzirira akatsetseka uye kunyange ma substrates, anobatsirwa zvakanyanya kubva mukubatanidzwa kweRDP.
Kuumbwa uye Zvivakwa zveRDP
RDP inotorwa kubva kumapolymers akadai sevinyl acetate, ethylene, uye acrylics. Iyo nzira inosanganisira kupfapfaidza-kuomesa emulsion yemvura kuti igadzire poda inogona kupararira zvakare mumvura, ichigadzira emulsion yakagadzikana. Yakakosha zvimiro zveRDP zvinosanganisira kugona kwayo kuvandudza kunamatira, kuchinjika, uye kuramba kwemvura mune zvekuvaka.
Kemikari Inoumbwa: Kazhinji, maRDPs anobva pane vinyl acetate-ethylene (VAE) copolymers. Aya mapolymer anozivikanwa nekuyerekana kwawo pakati pekuchinjika uye simba, achiita kuti ave akakodzera kune akasiyana ekuvaka ekushandisa.
Zvenyama Zvivakwa: RDP inowanzoita seyakanaka, chena hupfu. Kana yakasanganiswa nemvura, inoumba latex inogona kuwedzera zvimiro zvesamende musanganiswa. Uku kugona kudzoka kune yayo yekutanga emulsion fomu yakakosha pakuita kwayo mumakomisheni ekuzvimiririra.
Basa reRDP muSelf-Leveling Compounds
Kuzvimisikidza komisheni simende misanganiswa yakagadzirirwa kugadzira yakatsetseka uye nhanho nzvimbo pasina basa rakawanda. Kusanganisirwa kweRDP mumisanganiswa iyi kunounza akati wandei ekuwedzera:
Kuwedzera Kuyerera uye Kushanda: RDP inovandudza rheology yemusanganiswa, kuve nechokwadi chekuyerera kuri nani uye kupararira. Ichi chivakwa chakakosha kuti uwane nhanho yepamusoro nekuita kushoma. Iyo polymer particles inoderedza kukweshera kwemukati mukati memusanganiswa, ichibvumira kuti iyerere zviri nyore pamusoro pe substrate.
Enhanced Adhesion: Rimwe rematanho ekutanga eRDP ndere kusimudzira kunamatira kweiyo-yega-yepamusoro komisheni kune akasiyana substrates. Izvi zvinonyanya kukosha pakuona kuti musanganiswa unoumba chisungo chakasimba nehuriri huripo, ingave kongiri, huni, kana zvimwe zvinhu. Iwo mapolymer particles anopinda mukati me substrate pamusoro, achivandudza iyo mechaniki inopindirana uye makemikari bonding.
Flexibility uye Crack Resistance: Iko kuchinjika kunopihwa neRDP kunobatsira mukugadzika substrate mafambiro uye nekuwedzera kwemafuta, nekudaro kuderedza mukana wekupwanya. Uku kuchinjika kunonyanya kubatsira munzvimbo dziri pasi pekuchinja kwekushisa kana kufamba kudiki, kuve nechokwadi chekusimba kwenzvimbo yakasimudzwa.
Kuchengetedzwa Kwemvura: RDP inovandudza kuchengetedza kwemvura zvivakwa zvega-leveling compound. Izvi zvakakosha mukudzivirira kurasikirwa kwemvura nekukurumidza izvo zvinogona kutungamira mukushaikwa kwemvura yesimende, zvichikonzera kusasimba uye brittle nzvimbo. Kuchengetedzwa kwemvura kwakakwenenzverwa kunovimbisa kuti simende inopora nemazvo, kuwana simba rakakwana nekusimba.
Mechanical Strength: Kuvapo kweRDP kunosimudzira iyo yakazara mechanic zvimiro zveiyo yega-leveling kombi. Izvi zvinosanganisira kuvandudzwa kwekusimba uye kumanikidza simba, izvo zvakakosha pahupenyu hurefu uye kuvimbika kweiyo mhinduro yepasi. Iyo polymer firimu inoumbwa mukati me matrix inoita senge inosimbisa mumiriri, inogovera zvinonetsa uye inosimudzira kuvimbika kwechimiro.
Nzira Yekuita
Kubudirira kweRDP mumakomisheni ekuzvimiririra kunogona kunzwisiswa kuburikidza nemaitiro ayo ekuita:
Kugadzira Firimu: Pamusoro pe hydration uye nekuomeswa, zvimedu zveRDP zvinobatana kuti zvigadzire inoenderera polymer firimu mukati me simentitious matrix. Firimu iri rinoita sebhainda rinochinjika uye rakasimba rinobata matrix pamwechete, richisimbisa kubatana kwese.
Particle Packing: RDP inovandudza kurongedza density yezvimedu mune yekuzvimiririra komboni. Izvi zvinotungamira kune yakawedzera compact uye dense microstructure, kuderedza porosity uye kuwedzera simba.
Interfacial Bonding: Iyo polymer cheni dzeRDP dzinodyidzana nesement hydration zvigadzirwa, kuvandudza kubatanidzwa kwemukati pakati pemasevhisi esimende uye aggregate zvimedu. Ichi chisungo chakakwidziridzwa chinobatsira kuita zvirinani mechanic kuita uye kusimba.
Applications uye Benefits
Iko kubatanidzwa kweRDP mune yega-leveling makomisheni inowana mashandisirwo mumamiriro akasiyana siyana:
Mapurojekiti ekugadziridza: RDP-yakakwenenzverwa yekuzvimisikidza makomisheni yakanakira kugadzirisa yekare uye isina kuenzana pasi. Ivo vanopa inokurumidza uye inoshanda mhinduro yekuwana yakatsetseka uye nhanho yepamusoro yakakodzera kunotevera kuisirwa pasi.
Indasitiri Flooring: Muzvigadziro zvemaindasitiri uko pasi pari pasi pemitoro inorema uye traffic, iyo yakawedzerwa simba uye kusimba kunopihwa neRDP kunonyanya kubatsira.
Residence Flooring: Yezvishandiso zvekugara, RDP inova nechokwadi chenzvimbo yakatsetseka, isina kutsemuka inokwanisa kugarisa marudzi akasiyana ekufukidzira pasi, kusanganisira mataira, makapeti, uye pasi pemapuranga.
Underlayments for Radiant Heating: RDP-modified self-leveling makomisheni anowanzo shandiswa sepasi pekuisa inopenya yekudziya masisitimu. Kugona kwavo kuumba nzvimbo yakatsetseka uye nhanho inovimbisa kugovera kupisa kwakanaka uye kunoderedza njodzi yekukuvadzwa kwezvinhu zvekupisa.
Zvezvakatipoteredza uye Zveupfumi
Sustainability: RDP inogona kubatsira mukugadzirisa maitiro ekuvaka. Iko kukwidziridzwa kuita kwemakomisheni ekuzvimiririra kunoreva kuti zvinhu zvishoma zvinodikanwa kuti uwane iyo inodiwa yemhando yepamusoro, kuderedza kushandiswa kwezvinhu zvese. Pamusoro pezvo, iyo yakagadziridzwa kusimba kweRDP-yakakwidziridzwa pasi kunogona kutungamira kune hurefu hwehupenyu, kuderedza kudiwa kwekugadziriswa nguva nenguva uye kutsiva.
Kubudirira Kwemari: Nepo RDP inogona kuwedzera kumutengo wekutanga wekuzvimiririra makomisheni, mabhenefiti enguva refu anowanzo kupfuura mari yekutanga. Kuita kwakagadziridzwa, kuderedzwa kwemitengo yevashandi nekuda kwekushandisa kuri nyore, uye hupenyu hurefu hwekugadzirisa pasi kunopa zvakakosha zvehupfumi zvakanakira.
Redispersible Polymer Powder chinhu chakakosha chekuwedzera mu-self-leveling makomisheni, ichipa akawanda mabhenefiti anosimudzira mashandiro uye kusimba kwezvigadziriso zvepasi. Kugona kwayo kugadzirisa kuyerera, kunamatira, kuchinjika, uye simba remuchina kunoita kuti ive yakakosha mune zvese zvekugara uye zvemaindasitiri zvikumbiro. Nekunzwisisa kuumbwa, magadzirirwo, uye mabhenefiti eRDP, nyanzvi dzekuvaka dzinogona kuonga zvirinani basa rayo mukugadzira inoshanda uye inogara kwenguva refu yekuzvimisa makomisheni. Sezvo indasitiri yekuvaka iri kuramba ichishanduka, kukosha kwezvinhu zvepamusoro-soro seRDP zvinongowedzera, kutyaira hunyanzvi uye kusimba mukuvaka maitiro.
