Polymer kongiri: sezvamunoita, mifananidzo, unhu, kushanda rwokugadzira wongororo

Polymer kongiri - chaiyo chivakwa zvinhu, iro rinoshandiswa senzira bhainda, uyewo nokuda yaitsiva reraimu cements. Mune zvimwe zviitiko, polymer inoshandiswa sechinhu Kuwedzera Portland simende. Iri ichiita mabasa akawanda, hunogara anoumbwa nevazhinji zvinhu yaunganidzwa nokusanganisa siyana chicherwa fillers vane chakaita zvokugadzirwa kana dzinongoitika astringent nevamiririri. Izvi yepamusoro ouinjiniya zvinhu rinoshandiswa mumaindasitiri zhinji, asi ndiyo inonyanya pakuvaka indasitiri.

mhando

Pakuvaka akashandisa mhando nhatu polymer kongiri. Next, tikanyatsoongorora dzavo kugadzirwa ano, kukura uye akafanana kuva pfungwa mukuru polymer kongiri dzavo okunatsiridza.

Polymer kongiri nziyo (kongiri iri polymer-dzakachinjwa)

nekongiri mhando iyi yakaitwa kubva Portland simende zvinhu aine dzakachinjwa polymer akadai acrylic, polyvinyl acetate uye ethylene raive nebutiro acetate. Ane adhesion zvakanaka, matunhu simba flexural uye vakaderera permeability.

Acrylic polymer dzakachinjwa kongiri kunoratidzwa vairamba ruvara, iro ndokusaka ari kudiwa kukuru pakati Vavaki uye ezvivako. makemikari nadzurudzo Its hwakafanana kwakajairika esimende kushanduka. Huwandu polymer kazhinji anoda kubatsira kubva 10 kusvika 20%. Concrete, dzakachinjwa saizvozvi ane yakaderera mwero permeation uye arambe achirema kupfuura yakaisvonaka simende. Zvisinei, kuvimbika kwaro STRUCTURAL kunobva chaizvoizvo pamusoro bhainda pamusoro Portland simende.

kongiri kudzikisirana anogona kutora nguva refu kana ine mukuru arambe achirema uye duku pamusoro nzvimbo. The hama nani namakemikari kutsiga polymer-dzakachinjwa mashoko Portland simende angabvuma nenzira acidic svikiro.

Resin akaiswa mushonga wokuuraya kongiri

A nebwe impregnation nokuda kongiri anowanzoshandurwa chinoitirwa Pakusuma monomer iri pasi arambe achirema hydrated Portland simende, zvichiteverwa nemwaranzi kana chafariz polymerisation tiwedzere. The modular kuchinja kwaiita kongiri kubudikidza 50-100% kupfuura avhareji.

Zvisinei, kuti polymer modulus 10% mukuru kupfuura dzose kongiri. Nokuda kwazvo maitiro aya, pakati muzvizhinji zvaungasarudza kushandisa polymeric kuvaka zvinhu zvinogona ariega kutaurwa kugadzirwa:

• shop;
• mabhiriji;
• pombi;
• uriri usina kukonekita;
• laminate kuvakwa.

Pakusuma muitiro zvemichina kunosanganisira kongiri-nokuomesa kubvisa mwando pachiso, kushandiswa monomers nenzira nhete rukoko jecha, uye ipapo polymerizing kuti monomers uchishandisa kupisa nekubudisa. Naizvozvo, kongiri hukawanika vane yakaderera mvura permeability, Absorção de Água, abrasion kuzvidzivirira uye kazhinji yakakwirira simba. Uyewo, kuvandudza vapfeke nemishonga, kuramba chando uye mwando, anoshandiswa polymeric coatings kuti kongiri, zvidhina, ibwe, uriri, etc.

Polymer

It ane chokuita zvatinosiita kwatiri Portland. Kuvakwa Mabwe akabatana ane polymeric bhainda zvinhu usingabereki ane mvura. Polystyrene, acrylic uye epoxy Inogadzirwa nemasiridzi anobuda mumiti vari monomers ayo zvinowanzoshandiswa kugadzirwa kwaiita kongiri. Sarufa zvakare anoonekwa somunhu polymer. Sarufa kongiri rinoshandiswa kuti zvivako yaida yakakwirira kuramba acidic runyararo. Thermoplastic Polymers asi kazhinji thermosetting nebwe akashandiswa huru zvinoriumba nebwe nokuda kwavo yakakwirira chafariz kugadzikana uye kusimba-siyana makemikari.

Polymeric kongiri rinoumbwa vezvikwata izvo zvinosanganisira silica, Goldstone, girenayiti, reraimu uye humwe unhu zvokuvakisa. The chikwata inofanira kuva hwakanaka uye isina guruva, nemarara uye zvakawandisa unyoro. Kukundikana kutevera izvi zvinodiwa anogona kuderedza chisungo simba pakati polymeric bhainda uye filler.

Kunyanya polymer kongiri

Modern chivakwa zvinhu zvakasiyana kubva ayo vamutangira. Rine zvinotevera unhu:

• High nemishonga makemikari uye zvipenyu runyararo.
• Achienzaniswa simende-kongiri zvigadzirwa, ane zvishoma vakawanda.
• Zvakakwana absorbs ruzha uye vibrations.
• Vyvetrivaemost uye wakanaka UV nemishonga.
• The Absorção de Água.
• Rinogona kuchekwa kushandisa drills uye grinders.
• Inogona kupatsanurwa sezvo yakapwanyika dombo kana akapwanyika kushandiswa sezvo mugwagwa chawo.
• About 4 nguva nesimba kupfuura samende kongiri.
• Good kuputira zvivako uye isimbe.
• Ultra-kumugumo, izvo hwezvekukurukurirana hydraulic chokubuda nyatsoshanda.

kushandiswa

Polymer anogona kushandiswa zvitsva kuvakwa kana gadziridzo zvinhu yekare. namira ehupfumi Its kubvumira kuzoita zvose polymer uye kwakajairika kongiri, simende-chawo. Low permeability uye ngura nemishonga kubvumira kushandiswa kwayo muna swimming madziva, tsvina hurongwa, abudise migero, masero electrolytic nedzimwe nhengo ine mvura kana kungatikanganisa makemikari. Zvakakodzera pakuvaka uye kunaya matsime, nokuda kukwanisa kwayo kurwisa chepfu uye kungatikanganisa mapaipi magasi uye utachiona inowanzobvunzwa kuwanikwa mumvura enyika.

Kusiyana nezvaiitwa kongiri zvivako, izvozvo hakurevi chinhu unhani kana nomoto vazvo akadzivirira PVC. Unogona kuona kushandiswa polymer kongiri mumigwagwa. It rinoshandiswa pakuvaka zvipingamupinyi mumugwagwa, menzira, abudise inoerera, matsime. Uyewo munzira imwe polymer unhani nokuda kongiri inowedzerwa Asphalt mukuvakwa panze nzvimbo, runways nezvimwe zvivako, izvo dziri pachena mhepo uye vanongogara vachisangana nevanhu kwokunze weathering.

Reviews

The polymer kongiri haina nevakawanda vakagamuchirwa nokuda dzakakwirira mari uye zvinetso chokuita netsika mukugadzira michina. Zvisinei, kufambira mberi kuchangobva kwakatungamirira kuti chinokosha zvinoderedza mari, izvo zvinoreva kuti kushandiswa kwaro kuramba zvakajairika. Pasinei nezvose zvakanga zvakamunakira pamusoro kwakajairika kongiri, vane maonero pamusoro yakavigwa kunaka kwezvakatipoteredza zvinhu zvinowanzoitika nokuda mukugadzira kunaka, kushandisa yakaderera-unhu zvinoriumba uye kutyora zvikuru.

Uyewo, mabikirwo kugadzirwa polymer kongiri ane mugove nuances uye zvakavanzika kuti hapana anotsvaka kuzarurira. Uye chokwadi, sezvambotaurwa nokuda wongororo, polymer musika mutengo zvakakwirira zvikuru. Izvi imhaka kuoma kwayo kugadzirwa, uye zvinodhura zvinoriumba, izvo akashandisa kusika nayo.
