Kunyangwe zvese zviri zviviri silicone ndiro nerabha ndiro zvine kumwe elasticity uye yekuisa chisimbiso zvivakwa, pane misiyano yakakura mukuita kwavo, iyo inonyanya kukonzerwa neyakasiyana chimiro chemakemikari uye zvakakosha zvinhu.
Heino yakakosha kuenzanisa kwekuita:
Temperature Resistance: Silicone Sheets: Yakanyanya kusimba. Mashizha aya anochengetedza-kugadzikana kwenguva yakareba patembiricha yakawanda kubva-60 madhigirii kusvika +230 madhigirii, aine-kushivirira kwenguva pfupi kusvika pa250℃kana 300 degree. Izvi zvinoita kuti dzive dzakanakira-nzvimbo dzekupisa dzakaita sehovhoni, matireyi ekubikira, magaba akavharwa nekupisa, mapedhi ekudzivirira kupisa, uye masingi ekudziya emagetsi. Rubber Sheets: Yakaganhurirwa mukuita. Matembiricha chaiwo anoenderana nerudzi rwerabha: Natural Rubber: -50 dhigirii kusvika +70 dhigirii (inodzikisira patembiricha yepamusoro uye inoita brittle pakudziya kwakaderera). Styrene Butadiene Rubber (SBR): -40 dhigirii kusvika +100 dhigirii. Nitrile Rubber (NBR): -30 dhigirii kusvika +120 dhigirii (yakanakisa kuramba mafuta). Ethylene Propylene Diene Monomer (EPDM) Rubber: -50 dhigirii kusvika +150 dhigirii (mamiriro ekunze akanaka uye ozone kuramba). Fluororubber: -20 dhigirii kusvika +200 dhigirii kana kupfuura (kupisa kwakasarudzika uye makemikari kuramba, kunyange achidhura).
Chemical Kugadzikana uye Kuchembera Resistance:Silicone Sheets: Inoratidza kupikisa kwakasiyana kune oxygen, ozone, uye ultraviolet mwaranzi. Vanoratidza kuramba kuchembera kunoshamisa, kuchengetedza kuchinjika pasina kuomesa, kutsemuka, kana kurasikirwa kwekusimba kunyangwe mushure mekushandisa kwenguva refu, kazhinji vachipa hupenyu hurefu hwesevhisi. Mashizha aya anoratidza kushivirira zvakanaka kune zvinonyungudutsa zvinonyungudutsa (zvakadai sedoro, ketoni, nemamwe maasidhi), asi anoratidza kusamira zvakanaka kune-zvinonyungudutsa zvinonyungudutsa (eg, aliphatic hydrocarbons, aromatic hydrocarbons, petroleum{{5}based oils) nemaasidhi akasimba/alkali, zvingangokonzera kuzvimba kana kuora. Rubber Sheets: Kuchembera kuramba kunosiyana nemhando yezvinhu. Natural rabha uye styrene-butadiene rabha (SBR) inonzwa kuozone nemwaranzi yeUV, inoita kuputika nekuchembera. EPDM uye fluororubber inoratidza kukwirira kwemamiriro ekunze kuramba. Misiyano Yakakosha muChemical Resistance: Nitrile Rubber: Mafuta anosarudzika{11}}anodzivirirwa (petroleum{12}based oils, aliphatic hydrocarbons). Fluororubber: Yakanyanya makemikari kuramba (inopikisa mafuta, acids, alkalis, solvents). Natural Rubber: Inopikisa kune isina simba acids / alkalis asi kwete mafuta / zvinonyungudutsa. EPDM: Inoshingirira kumvura, chipfunga, maasidhi asina simba/alkali, uye zvinonyungudutsa mupolar, asi kwete mafuta kana zvinonyungudutsa zvehydrocarbon.
Panyaya yekupikisa kwemakemikari, marudzi ese ane maonero akasiyana uye anofanirwa kusarudzwa zvichibva pane chaiyo yekusangana midhiya.
Zvenyama uye zvemagetsi zvivakwa: Silicone rabha mapepa: Mechanical simba (tensile uye kubvarura simba) kazhinji yakaderera pane akawanda rubber. Nepo vachiratidza kunyoroka, kuita kwavo kwechigarire deformation kunogona kusaenderana nemamwe marubha epamusoro (kunyanya pasi pekudzvanywa kwe tembiricha-yakareba). Ivo vanoratidza yakanakisa kudzoreredza kusimba uye vanochengeta yakanaka kuchinjika pakudziya kwakaderera. Mashizha eRubber: Kazhinji anoratidza simba repamusoro remagetsi (kunyanya kusimba uye kubvarura simba). Permanent compression deformation performance inosiyana nemhando uye magadzirirwo, aine mamwe marubha (eg, EPDM) anoita zvakanaka. Recovery resilience kazhinji inogutsa. Kudzikira-kusanduka kwe tembiricha kunoenderana nerudzi rwezvinhu (semuenzaniso, rabha remusikirwo rinoita zvirinani kana tembiricha yakaderera ukuwo nitrile rabha ichiomesa mumamiriro ekutonhora).
Electrical Insulation:Silicone Sheets: Iva neakanakisa emagetsi ekudzivirira zvivakwa ane yakakwirira resistivity uye dielectric simba, inochengetedza kugadzikana pane dzakasiyana siyana tembiricha uye ma frequency. Inoshandiswa zvakanyanya mumagetsi uye magetsi ekuisa insulation application. Rubber Sheets: Kazhinji anoratidza zvakanaka magetsi ekudzivirira (kunyanya EPDM), asi angasaenderana nekuchena uye kugadzikana kwesilicone. Mamwe marabha (semuenzaniso, conductive rubber ane kabhoni dema) anogona kugadzirwa kuitira conductivity kana antistatic properties. Mhedziso: Silicone inotaridza kunaka kwepamusoro mu-kupedza magetsi ekuvharisa (kunyanya munzvimbo dzakakwirira-nepamusoro-nzvimbo dzenguva zhinji). Biocompatibility uye Isiri{{10}chepfu Masikirwo: Silicone Sheets: Anoratidza kukwirira kwechimiro chemuviri uye kugarisana kunoshamisa. Inogadzirwa zviri nyore kuita zvigadzirwa zvinoenderana neChikafu Giredhi (FDA, LFGB) uye Medical Giredhi (USP Kirasi VI) zviyero. Haina hwema uye utachiona{13}}hushingirira. Rubber Sheets: Siyana zvakanyanya mu biocompatibility. Natural rubber inogona kukonzera allergies. Kuti uwane certification yeChikafu Giredhi kana Medical Grade, kusarudzwa kwakasimba kwezvinhu nezvinowedzerwa (vulcanizing agents, accelerators, anti{17}}anti age agents, etc.) zvinodiwa. Izvi zvinowedzera zvinotakura njodzi dzekufambisa dzakakwirira zvichienzaniswa nesilicone, inogona kuburitsa hwema hwerabha.
Gasi permeability: Silicone sheets: Zvishandiso izvi zvinoratidza kupinza kwakanyanya kumagasi (semuenzaniso, mweya) uye mhute yemvura. Nepo ichi chivakwa chinobatsira kune mamwe maapplication (semuenzaniso, mapedhi anofema, machira ekufema membrane), zvinogona kuratidza kusakosha mukusunga zvikumbiro. Mashizha eRubber: Kazhinji ane gasi rakaderera permeability, kunyanya butyl rabha, rinoshanda sechinhu chakanakisa chisina mhepo.
Mhedziso: Rubber kazhinji iri nani pakugadzira zvisimbiso zvisingapindi mhepo uye zvisina mvura. Unhu hwepamusoro: Silicone plate: Iyo yepamusoro ndeye hydrophobic (kuvenga mvura), haibatike nyore kune zvakawanda zvinhu, zviri nyore kuchenesa. Rubber plate: Mamiriro epamusoro anosiyana zvichienderana nerudzi uye fomula, mamwe anogona kunamira.
Mutengo: Silicone ndiro: inodhura. Mutengo wezvigadzirwa uye mutengo wekugadzira unowanzo kukwira pane zvakajairika rabha. Rubber plate: yakawanda yemitengo. Natural rabha, SBR, NBR uye mamwe anowanzo shandiswa rabha mutengo wakaderera. Special rabha (senge fluororubber, silicone rabha pachayo) mutengo wakakwira.
Sarudzo yezvekupedzisira inofanirwa kutariswa nekushandisa-zvakananga zvinodiwa zvinosanganisira tembiricha yekushanda, kubata nechemical media, mechanical load, chikafu-giredhi/medical-giredhi inoenderana, mhepo inodiwa, uye kunetsa kwebhajeti.
Ese ari maviri silicone uye rabha imwe neimwe inoratidza isingadzokerike mabhenefiti muminda yavo
