Kuisa chisimbiso ihwo huzhinji tekinoroji inodiwa kune ese maindasitiri, kwete chete kuvaka, petrochemical, shipbuilding, michina kugadzira, simba, chekufambisa, kuchengetedza kwezvakatipoteredza uye mamwe maindasitiri haagone kuita pasina chisimbiso tekinoroji Aviation, aerospace uye mamwe maindasitiri ekucheka-kumucheto ane hukama zvakanyanya teknolojia yekuisa chisimbiso.Kuisa chisimbiso tekinoroji inoshandiswa zvakanyanya muminda yakawanda, senge yekuchengetera mvura, yekufambisa uye shanduko yesimba.

Kukosha kwekuisa chisimbiso tekinoroji mhedzisiro yekusavhara chisimbiso yakakomba, mwenje wekudonha, zvichikonzera kutambisa simba uye zviwanikwa, zvinorema zvichaita kuti oparesheni ikundikane, uye kunyange kuburitsa moto, kuputika, kusvibiswa kwezvakatipoteredza uye zvimwe zvinokonzeresa zvinokanganisa kuchengetedzwa kwemunhu. .

Nekuvandudzwa kwesainzi uye tekinoroji, mamiriro ekushanda ekuisa chisimbiso akanyanya kuoma.Sezvo tembiricha, kudzvanywa uye kuora kwemvura yakavharwa kuri kuwedzera zvakanyanya, izvo zvechinyakare zvekuisa chisimbiso zvakadai sekunzwa, hemp, asbestos, putty uye zvichingodaro hazvigone kuzadzisa zvinodiwa zvekushandisa, uye zvishoma nezvishoma zvinotsiviwa nerabha uye zvimwe zvekugadzira zvinhu.

Synthetic zvinhu zvakaita serabha anowanzo macromolecular polymers, umo mapoka anoshanda ane hunhu hwakasiyana (senge chlorine, fluorine, cyano, vinyl, isocyanate, hydroxyl, carboxyl, alkoxy, nezvimwewo) anove anoshanda muchinjiko-kubatanidza mapoinzi.Pasi pechiito checatalyst, kurapa mumiriri, kana tembiricha yakakwira uye nemwaranzi yemagetsi, macromolecule inoshanduka kubva mumutsara dhizaini uye dhizaini chimiro kune spatial network chimiro, maitiro aya anonzi kurapa.Vulcanized rabha kana zvimwe zvinhu zvekugadzira, macromolecules anorasikirwa nekufamba kwepakutanga, inozivikanwa seyepamusoro elastic deformation ye elastomer.

Common Rubber uye zvigadzirwa zvekugadzira ndezvi: natural rabha, styrene-butadiene, neoprene, butadiene rabha, Ethylene propylene rabha, butyl rabha, polyurethane rabha, acrylate rabha, fluorine rabha, silicone rabha uye zvichingodaro.

6 Performance Indexes Yekuona Hunhu hweKuisa Chisimbiso Zvishandiso

1. Tensile Performance

Tensile zvivakwa ndizvo zvakanyanya kukosha zvivakwa zvekuisa chisimbiso, zvinosanganisira kusimba kusimba, kuramba kusimba kushushikana, kureba panguva yekuzorora uye kusingaperi deformation panguva yekuzorora.Kusimba kwesimba ndiko kushushikana kwakanyanya uko muenzaniso wakatambanudzwa kusvika pakutyoka.Constant elongation stress (modulus yekugara kurebesa) ndiko kushushikana kunosvika pakurebesa kwakatarwa.Elongation (elongation) iko kushanduka kwechimwe chienzaniso chinokonzerwa nechisimba chakataurwa.Chiyero chekuwedzera kwekuwedzera kune urefu hwepakutanga chinoshandiswa.Kurebesa panguva yekuzorora ndiko kurebera pakuputika kwemuenzaniso.The tensile permanent deformation ndiyo yakasara deformation pakati pemitsara yekumaka mushure mekutyoka.

2. Kuoma

Kuomarara kweiyo yekuisa chisimbiso kuramba kumanikidzwa kwekunze mukugona, asiwo imwe yeakakosha kuita kwekuisa chisimbiso zvinhu.Kuoma kwezvinhu kunobatana nezvimwe zvinhu kune imwe nhanho.Kunyanya kuoma, kusimba kwesimba, kuderera kwehurefu, zviri nani kupikisa kupfeka, uye zvakanyanya kuderera kwekushisa.

3. Compressibility

Nekuda kweiyo viscoelasticity yezvinhu zverubha, kudzvanywa kunoderera nekufamba kwenguva, izvo zvinoratidza senge compressive kusagadzikana kuzorora, uye haigone kudzoka kune yekutanga chimiro mushure mekubvisa kudzvanywa, kunoratidza sekumanikidza kwekusingaperi deformation.Mukupisa kwepamusoro uye svikiro remafuta ichi chiitiko chinonyatso kuoneka, kuita uku kwakanangana nekusimba kwezvigadzirwa zvekuisa chisimbiso.

4. Low Temperature Performance

Indekisi inoshandiswa kuyera yakadzika tembiricha maitiro echisimbiso cherabha Idzi nzira mbiri dzinotevera dzekuyedza kudzika-tembiricha kuita: 1) yakaderera-tembiricha yekudzoreredza tembiricha: iyo yekuisa chisimbiso yakatambanudzwa kune imwe hurefu, yozogadziriswa, nekukurumidza kutonhora kusvika kune inotonhora tembiricha. pazasi, mushure mekusvika pakuenzanisa, sunungura chidimbu chekuyedza, uye pane imwe mwero yekudziya, rekodha maitiro ekudzosa 10% , 30% , 50% uye 70% kana tembiricha inoratidzwa se TR10, TR30, TR50, TR70.Iyo yezvinhu chiyero ndeye TR10, ine hukama neiyo Brittleness tembiricha yerabha.Kudzika kwetembiricha kuchinjika: Mushure mekunge sampu yave nechando kusvika panguva yakatarwa panguva yakatarwa yakaderera tembiricha, sampu inokotama ichienda mberi neshure zvichienderana nekona yakatsanangurwa kuti iongorore kugona kwekuvharisa kwechisimbiso mushure mekudzokorora chiito chesimba resimba pakudziya kwakaderera.

5. Mafuta Kana Medium Resistance

Pamusoro pekubatana nemafuta-based sealing materials, double esters, silicone oiri, muindasitiri yemakemikari dzimwe nguva inobata acid, Alkali uye imwe corrosive media.Pamusoro pekuora mune iyi midhiya, pakupisa kwakanyanya kuchaitawo kuti kuwedzere uye kuderedza simba, kuderedza kuoma;panguva imwecheteyo, iyo yekuisa chisimbiso plasticizer uye soluble zvinhu zvakaburitswa kunze, zvichiita kuti uremu huderedze, kuderedzwa kwevhoriyamu, zvichikonzera kuvuza.Kazhinji, pane imwe tembiricha, shanduko yeMisa, vhoriyamu, simba, kurebesa uye kuoma mushure mekunyudzwa mukati menguva kwenguva yakati inogona kushandiswa kuongorora kupikisa kwemafuta kana kupikisa kwepakati kwezvinhu zvekuisa chisimbiso.

6. Kuramba Kuchembera

Kuisa chisimbiso zvinhu neokisijeni, ozone, kupisa, chiedza, mvura, mechanical stress zvinotungamirira mukuderera kwekuita, kunozivikanwa sekukwegura kwezvinhu zvekuisa chisimbiso.Kuchembera Resistance (inozivikanwawo semamiriro ekunze kuramba) inogona kushandiswa mushure mekuchembera kwesimba, kurebesa, kuomarara shanduko kuratidza kuti idiki shanduko yekuchinja, zviri nani kuramba kuchembera.

Ongorora: weatherability inoreva nhevedzano yezviitiko zvekuchembera, sekupera, kushanduka kwemavara, kutsemuka, kuita hupfu uye kuderedzwa kwesimba rezvigadzirwa zvepurasitiki nekuda kwesimba remamiriro ekunze akadai sekuvhenekwa kwezuva, kushanduka kwekushisa, mhepo nemvura.Ultraviolet radiation ndechimwe chezvinhu zvakakosha kukurudzira kuchembera kwepurasitiki.
