Mashandisirwo akajairika eupfu hwepolymer hunopararira

Upfu hwerabha hunogadzirwa nekupisa kwakanyanya, kumanikidzwa kwakanyanya, kuomesa nepfapfaidzo uye homopolymerization ine mhando dzakasiyana dzeupfu hunowedzera simba, izvo zvinogona kuvandudza kugona kwekubatanidza uye simba rekusunga kwedhaka. , mashandiro akanaka ekukwegura kwekupisa, zvinhu zviri nyore kushandisa, zviri nyore kushandisa, zvinotibvumira kugadzira dhaka rakasanganiswa rakaoma remhando yepamusoro. Mashandisirwo akajairika eupfu hwepolymer hunopararira ndeaya:

Zvinonamira: zvinonamira zvemataira, zvinonamira zvekuvaka uye zvinodzivirira kupisa;

Dura remadziro: dhaka rekunze rekupisa rinopisa, dhaka rekushongedza;

Dura repasi: dhaka rinozvienzanisa, dhaka rekugadzirisa, dhaka risingapindi mvura, mumiririri wehupfu hwakaoma;

Kuputira neupfu: maplaster e lime-simende uye machira akagadziridzwa ne putty powder uye latex powder yemadziro nedenga remukati nekunze;

Chinozadza: tile grout, dhaka rekubatanidza.

Upfu hwelatex hunonyungudika zvakareHaifanirwe kuchengetwa uye kutakurwa nemvura, zvichideredza mari yekufambisa; nguva refu yekuchengetedza, antifreeze, iri nyore kuchengeta; vhoriyamu diki yekurongedza, huremu hwakareruka, nyore kushandisa; Inogona kushandiswa se premix yakagadziriswa ne synthetic resin, uye inongoda kuwedzera mvura kana ishandiswa, izvo zvinodzivirira zvikanganiso pakusanganisa panzvimbo yekuvaka chete, asiwo zvinovandudza kuchengetedzeka kwekubata kwechigadzirwa.

Mumota, chinangwa ndechekuvandudza kusasimba kwemota yechinyakare yesimbi yakadai sekuomarara uye elastic modulus yakakwira, uye kupa simende simbi kuchinjika kuri nani uye simba rekusungana kuti irambe nekunonotsa kugadzirwa kwemota yesimbi yesimbi. Sezvo polymer nemota zvichiumba chimiro chenetwork chinopindirana, firimu repolymer rinogara richigadzirwa mumapores, izvo zvinosimbisa chisungo pakati pema aggregates uye zvinovhara mamwe mapores ari mumota. Nokudaro, mota yakagadziriswa mushure mekuoma ine mashandiro ari nani pane mota yesimbi yesimbi.

Upfu hwepolymer hunopararira hunoparadzirwa mufirimu uye hunoshanda sekusimbisa sechinamira chechipiri; colloid inodzivirira inonyudzwa nesystem yemortar (firimu harizoparadzwe nemvura mushure mekuumbwa kwefirimu, kana "kupararira kwechipiri"); resin yepolymer inogadzira firimu Sechinhu chinosimbisa chinoparadzirwa musystem yese yemortar, nokudaro zvichiwedzera kubatana kwemortar.
