suma:
Self-leveling kongiri (SLC) imhando yakakosha yekongiri yakagadzirirwa kuyerera uye kupararira zviri nyore pamusoro penzvimbo, ichigadzira nzvimbo yakati sandara, yakatsetseka pasina kudiwa kwekunyanyisa kutsetseka kana kupedzisa. Rudzi urwu rwekongiri runowanzoshandiswa mukuisa pasi pasi apo nzvimbo yakatsetseka uye yunifomu yakakosha. Kuwedzeredzwa kweadhispersible polymer poda (RDP) kune yega-yepamusoro kongiri yave tsika yakajairika muindasitiri yekuvaka nekuda kwekuwanda kwayo.
Chii chinonzi RDP?
Redispersible polymer poda (RDP) icopolymer poda ye ethylene uye vinyl acetate. Inowanzo kugadzirwa nekupfapfaidza kuomesa vinyl acetate-ethylene copolymer emulsion. Iyo hupfu inogona kuparadzirwa mumvura kuti iite emulsions yakagadzikana, ichibvumira kuti ishandiswe sebhainda mune zvakasiyana-siyana zvekuvaka, kusanganisira self-leveling concrete.
Zvakanakira zveRDP mune yega-leveling kongiri:
Kuvandudza kuchinjika uye kusimba:
RDP inokwidziridza kuchinjika kwekongiri yekuzvimisikidza, ichiita kuti isarambe kutsemuka. Izvi zvinonyanya kukosha mumashandisirwo apo iyo kongiri yepamusoro inogona kunge iri pasi pekufamba kana kushushikana.
Wedzera adhesion:
Izvo zvinosungirirwa zvekongiri yekuzvimiririra zvakakosha pakuita kwayo. RDP inovandudza kusungirirwa kwekongiri kune akasiyana ma substrates, kuve nechokwadi chisungo chakasimba uye chinogara kwenguva refu.
Deredza kunyura kwemvura:
RDP inogona kuderedza kunyura kwemvura kwekongiri yekuzvimiririra, ichiita kuti isarambe kukuvara kwemvura uye nekuvandudza kusimba kwayo kwenguva refu.
Kuvandudza machinability:
Kuwedzerwa kweRDP kunowedzera kushanda kwekongiri yekuzvimisa, zvichiita kuti zvive nyore kusanganisa, kudira uye kupedza. Izvi zvakagadziridzwa kushanda zvinobatsira kuwana nzvimbo yakatsetseka, inowirirana.
Inodzorwa kuseta nguva:
RDP inogona kugadzirwa kudzora nguva yekumisikidza yekongiri yekuzvimiririra. Izvi zvinobatsira pamapurojekiti ekuvaka anoda nguva chaiyo yekumisikidza kuti uwane mhedzisiro.
Crack resistance:
Kushandisa RDP mu-self-leveling kongiri kunobatsira kuderedza mukana wekutsemuka kuumba panguva uye mushure mekurapa. Izvi zvinonyanya kubatsira munzvimbo dzakanyanya-kushushikana.
Zvakasiyana-siyana:
Self-leveling kongiri neRDP inogona kushandiswa mumhando dzakasiyana dzekushandisa, kusanganisira dzekugara, dzekutengesa uye dzeindasitiri. Kusarudzika kwayo kunoita kuti ive sarudzo yakakurumbira yemapurojekiti epasi.
Economic uye inoshanda:
RDP inodhura-inoshanda kana ichienzaniswa nezvimwe zvekuwedzera. Kushanda kwayo mukusimudzira kushanda kwekongiri yekuzvimisa kunobatsira mukudhura kwese kwezvirongwa zvekuvaka.
Kushandiswa kweRDP mune yega-leveling kongiri:
Mixing process:
RDP inowanzowedzerwa panguva yekusanganiswa kwekongiri yekuzvimiririra. Inosanganiswa nezvimwe zvakaoma zvinosanganisa sement, aggregates uye zvimwe zvinowedzera, uye ipapo mvura inowedzerwa kuti iite homogeneous uye inoshanda musanganiswa.
dose:
Huwandu hweRDP hunoshandiswa hunogona kusiyana zvichienderana nezvinodiwa zvepurojekiti uye zvimiro zvinodikanwa zvekongiri yekuzvimiririra. Vagadziri vanowanzopa inokurudzirwa dosage nhungamiro zvichienderana nerudzi rweRDP inoshandiswa uye mashandisirwo.
kugarisana:
Izvo zvakakosha kuve nechokwadi chekuti RDP yakasarudzwa inoenderana nezvimwe zvinongedzo zvega-leveling kongiri musanganiswa. Nyaya dzekuenderana dzinogona kukanganisa mashandiro uye maficha echigadzirwa chekupedzisira.
mukupedzisa:
Muchidimbu, kushandiswa kwehupfu hwepolymer hupfu (RDP) mukongiri yekuzvimisa-yega kunopa akawanda mabhenefiti, kubva pakuvandudza kuchinjika uye kunamira kune yakawedzera kushanda uye kuramba kutsemuka. Iko kushandiswa kweRDP kwave tsika yakajairika muindasitiri yekuvaka, kunyanya mumapurojekiti epasi apo nhanho uye yakasimba nzvimbo yakakosha. Sezvo tekinoroji ichienderera mberi, kuenderera mberi nekutsvagisa uye kusimudzira mumunda wezvekuwedzera kongiri kunogona kutungamira kune mamwe magadzirirwo ekugadzirisa kuita kwakaringana kwezvivakwa zvekuvaka.
