Zvinhu uye zvinhu zvakanaka zve rubber-bitumen mastics
Mastic, yakagadzirirwa pahwaro hwerabha uye bhitumini, chinhu chimwe-chinoputira, chinova chipingamupinyi chisingakundiki kune unyoro. Iyo inoumba chitubu chinopfuurira umo, pasinei nekushanduka kwekushisa kwekunze, hurumende yakagadzikana yekushisa inochengetedzwa, iyo inononoka zvikuru maitiro ekuora uye kuora kwezvinhu zvesimbi.
Rubber-bitumen mastics ndeyeboka rezvinonzi "inotonhora" mastics, iyo inoshandiswa kune dzakavharwa zvikamu zvemotokari mushure mekutanga kupisa, asi pamhepo yekupisa (kupisa kunongotarisirwa kuderedza zvishoma viscosity yekuumbwa, kuti zvive nyore. yekushanda nayo). Mukuwedzera, chimwe nechimwe chezvikamu chinoita mabasa anonyatsotsanangurwa. Rubha inowedzera elasticity ye mastic uye kuramba kwayo kupeta panguva yekurova kana kuvhunduka, uye bhitumini inobatsira kuhydrophobicity ye mastic uye kuramba kwayo kunzvimbo dzine hutsinye hwemakemikari (asidi nemaalkali).
Sezvo chero bituminous base zera nekufamba kwenguva uye inorasikirwa nekusimba kwayo, mapolymeric makomisheni anowedzerwa kune mastic, iyo inowedzera kupfava. Izvi zvinodikanwa kuti ushandise BPM series rubber-bhitumen mastics gore rose.
Maitiro ekushanda kwezvinyorwa zviri kutariswa:
| Mastic brand | Kunyorova tembiricha, ° С | Elongation plasticity, mm | Kurebesa kwehukama pakutanga kwekuputika,% | Tembiricha yekushandisa, ° С |
| BPM-3 | 50 | 3 ... 5 | 60 | 10 ... 30 |
| BPM-4 | 60 | 4 ... 8 | 100 | 5 ... 30 |
Mastic BPM-3
Mastic BPM-3Kana yakashandiswa kune simbi yemotokari, iyo yakagadzirwa inoita mabasa anotevera:
- Inodzivirira simbi kubva pakuora.
- Inoderedza ruzha mukamba.
- Inoita mechanical kudzivirira kwepasi kubva kune dzakasiyana-siyana munyu, dombo rakapwanyika, matombo.
- Inobatsira kuderedza vibrations.
Kuvapo kwerabha yakanaka mukuumbwa kunovimbisa kukwana kwakaringana kwejasi, iro rinochengetwa kunyangwe pakadzika tembiricha (kusvika -15 ... -200NE).
Zvinyorwa zveAluminosilicate zvinounzwa mukuumbwa kweBPM-3 mastic, kuvapo kwayo kunodzivirira nhengo dzekunze dzemuviri kubva kumitoro ine simba. Panguva imwecheteyo, mechanical wear resistance inovandudzwa. Iyo bituminous chikamu inobatsira mukuenderera kwakakodzera kwekuputira uye inoderedza nzvimbo yemahara nzvimbo.
Mastic inopfuta, saka inokurudzirwa kushanda nayo munzvimbo dzine mhepo inofefetera, kure nenzvimbo dzemoto wakavhurika. Usati washandisa mastic inopisa mubhati remvura kana muimba inodziya. Iyo yakagadzirwa yakagadzirira kushandiswa kana iri homogeneous viscous sticky mass yeruvara rutema.
Mastic BPM-4
BPM-4 inzira yakavandudzwa yeBPM-3 mastic. Kunyanya, kune zvikamu zvinowedzera modulus ye elasticity yezvinhu, iyo ine simba rakanaka pakugara kwekuputira.
Mukuwedzera, BPM-4 rubber-bitumen mastic inoratidzwa ne:
- Kuvapo kweamine-ine petroleum oiri, iyo inopa imwe yekuwedzera anti-corrosion effect inogara kwenguva yakareba.
- Kuwedzera elasticity yenzvimbo yakarapwa, iyo inonyanya kukosha kumotokari dzinoshandiswa mumigwagwa yakaipa.
- Kuwedzera kushamwaridzana kwezvakatipoteredza panguva yekushandiswa, sezvo isina zvinhu zvinogumbura hurongwa hwekufema.
Izvo zvakasara zvekushanda parameters zvinoenderana nekugona kweBPM-3 mastic.
Kugadzirwa kwerabha-bhitumen mastics mamakisi BPM-3 uye BPM-4 inoitwa maererano nehunyanzvi zvinodiwa zveGOST 30693-2000.
User Reviews
Yakawanda wongororo inoratidza zvinotevera maficha ekushandiswa kwemhando idzi dzemastics:
- Iko kudiwa kwekushandisa zvitete, kubva mumamiriro ekutanga (kunyangwe mushure mekunyorovesa kwekupisa) zvakaoma kushandisa mastics, kunyanya pazvimiro zvine dhizaini yakaoma. Gasoline Kalosh, parafini, toluene inokurudzirwa semakomponi ekuderedza. Zvisinei, huwandu hwese hutete hunofanira kudarika 15% yepakutanga mastic volume.
- Dzimwe wongororo dzinocherechedza chokwadi chekuchembera kwemuviri wejasi rakabatwa neBPM-3, iyo varidzi vemotokari vari kunetsekana nayo nekuunza mapurasitiki mune mastic. Mune chinzvimbo ichi, unogona kushandisa yakasefa injini oiri.
- Inofananidzwa neBPM-3, BPM-4 mastic inogona kushandiswa mune imwe nhanho, asi isati yasvika inokurudzirwa kunyatsochenesa uye kubvisa pasi, pamwe nekushandisa phosphate-containing primer.
- Kusiyana nezvimwe zvigadzirwa zvakafanana - semuenzaniso, Kordon anticorrosive - Nizhny Novgorod mastics haitseki pane yakaderera ambient tembiricha.
Vashandisi vanofungawo "kushamwaridzana" kwezvose zviri zviviri sechinhu chakanaka, chinobvumira kushandiswa kwemamwe mabhureki ezvigadzirwa zvakafanana.
