2. Kusarudzwa kwezvinhu zvakajairika kusimbisa zvinhu zvakasiyana kune yavo zvakanakira uye zvakashata maererano nemimwe yemakemikari kurwisa, tembiricha kuramba uye manhamba ekuzvidzivirira.
Izvi zvinotevera zvakati wandei zvakajairika chisimbiso zvinhu uye zvavanoshandisa mune yakasimba acid uye alkali nharaunda:
2.1 Fluoroelastomer (FKM / Viton) Fluoroelastomer (FKM) chinhu cheRabha chine yepamusoro yemakemikari kuramba Simba rayo riri kuramba richipikisana nemhemberi dzakakwirira, pamwe nekuita kwayo kwakanaka mumafuta, mafuta uye akawanda organic sol sol. Nekudaro, viton isinganyanyokira kushoma kune zvigadziko zvakasimba (semuenzaniso, sodium hydroxide, potasasum hydroxide), saka hazvikurudzirwe kushandiswa munzvimbo dzakasimba dzeAlkaline.
Zvakanakira: Kuramba kwakanaka kune yakasimba acids uye yakanyanya kupisa kupisa.
Zvinokuvadza: Murombo kuramba kune yakasimba Alkali, mutengo wakakwira.
Nzvimbo Inoshanda: Yakasimba acid nharaunda, kunyanya mune yakanyanya tembiricha inodiwa.
2.2 Perfluoroelastomer (Ffkm / Perfluoroelastomer) Perfluoroelastomer (Ffkm) ndeimwe yeElasomer Zvigadzirwa neiyo yepamusoro yepamusoro yemakemikari. Izvo zvinodzivirira kune ese marudzi ese eAcids, Alkalis, solvents uye mamwe makemikari, uye anoramba akagadzikana pakupisa kwakanyanya. Izvi zvinyorwa zvinochengeta zvivakwa zvayo zvekurara kwenguva yakareba, kunyangwe mumamiriro ezvinhu akanyanyisa, uye "pamusoro peiyo" mutsara "pakati pekuiswa kwemidziyo muindasitiri yemakemikari.
Zvakanakira: Kuramba kwemakemikari kwakanaka, kupisa kwakanyanya, kwakakodzera kumamiriro ezvinhu ekushanda zvakanyanya.
Zvinokuvadza: mutengo wakanyanya wakanyanya, hauna kukodzera nekuda kwekushanda kwakakura-chiyero mumidziyo inodhura.
Nzvimbo Inoshanda: yakasimba acid, Alkali, yakanyanya tembiricha uye yakanyanya kuora nharaunda.
2.3 PolytetraFluorohlene (PTFE / TEFLON) PolytetraFluorohlene (PTFE) ine yakanyanya kukwira kemikari kugadzikana uye kurwisa kurwisa, uye kusanzwisisika kune chero acid, alkali kana solvent. Kuwedzera kune izvi, PTFE inokwanisa kutsungirira zvakanyanya kupisa kwakanyanya uye saka inoshandiswa zvakanyanya mune yakasimba acid uye alkali nharaunda. Yayo chete dhizaini ndeyevarombo yayo, iyo inoda kusanganiswa nevamwe velastomers kuti uwane mhedzisiro iri nani yekuenzanisa.
Zvakanakira: Komani anoramba, akanyanya kupisa anopesana, akakodzera kune anenge ese anenge ese anokanganisa nharaunda.
Zvinokuvadza: Murombo Elasticity, ingangoda kushandiswa pamwe chete nezvimwe zvinhu.
Nzvimbo Inoshanda: Yakasimba acid, yakasimba Alkali, solvent uye yakakwira tembiricha mamiriro.
2.4 ethylene proylene Rubber (Epdm) Etylelene Rubber (Epdm) anoita zvakanaka mune yakasimba alkaline nharaunda, uye yakakodzera zvakanyanya kune zvinoshandiswa mukusangana neAlkaline mhinduro. Zvakare, EPDM ine kuramba kwakanaka kumhinduro dze acidic pane zvimwe zvekuvhunduka. Nekudaro, iyo isinganyanye kuramba kune chirairo chemaminerari uye organic sol sol, saka haina kukurudzirwa kuti zvikumbiro zvinosanganisira mafuta.
Zvakanakira: Kuita kwakanaka kwazvo muAlkaline nharaunda, zvine mwero mutengo.
Zvinokuvadza: kwete kuramba mafuta uye organic sol sol.
Nzvimbo Inoshanda: Yakasimba alkaline nharaunda, yakakodzera kune yakaderera uye yepakati yekushongedza acidic nharaunda.
2,5 chloroprene rubha (cr / neoprene) chloroprene rugara ine imwe nhanho yekurwisa, uye inoita zvakanaka mune yepakati-simba acid uye alkali mhinduro. Iyo inodarika mu ocidation uye ozone kuramba uye isingadhuri, ichiita kuti iite kuti ishandiswe mukushandisa mafambiro okushanda kweutorwa haasi akanyanya kukwirira.
Zvakanakira: ozone kuramba, oxidation kuramba, mutengo wakaderera.
Zvinokuvadza: Kwete yakakodzera kune yakasimba acid uye alkali nharaunda.
Nzvimbo yakakodzera
3. Inoshanda mashandiro ekushandisa kwekusarudza kwezvinhu mune zvinoshanda zvinoshandiswa, zvinhu zvinotevera zvinofanirwa kutariswa kana uchisarudza chisimbiso:
Kemical Resistance : Sarudza mhando huru dzemakemikari (Acids, alkalis kana solvent) uye zvavakatarisana nenzvimbo kuti ive nemakemikari ekuramba kwezvinhu zvakasarudzwa.
Tembiricha yekudziya: tembiricha tembiricha chinhu chakakosha, kunyanya mumamiriro ezvinhu epamusoro apo iyo yekudzikisira iyo kugadzikana kwezvinhu zvakakosha.
Mashini ekushushikana: semuenzaniso kushushikana (semuenzaniso kudzvinyirira, shear, etc.) izvo zvinogona kugadzirwa panguva yekushanda kwemidziyo inoda kusarudzwa kwechinhu chine huwandu hwakaringana uye simba.
Zvekare zvezvikwereti: Kana mutengo unonzwa, unogona kushandisa zvinhu zvakakwirira zvakadai seFFKM munzvimbo dzakarongeka, uchisarudza zvinhu zvinodhura senge EPDM munzvimbo dzakawanda dzakadzama.
. Fluorine Rubber, Perfluoroether Rubber, PolytetraFluoroothery neErtylene Rubber uye zvimwe zvinhu zvakaringana, kusarudzwa kwenzvimbo kunoda kuenderana nemakemikari zvivakwa, tembiricha, kushushikana, kushushikana uye zvinhu zvinodhura. Kune nharaunda dzakanyanyisa, pfe uye pfe uye ptfe zvakanakira, nepo mune inodhura-inotyisa kana isingasviki yekunyorera, EPDM uye neoprene akakodzera dzimwe nzira dzakakodzera.
