Silicone rabha: Preparation, Properties uye Applications

Silicone rabha achangobva kuva akakurumbira chaizvo zvinhu. Zvemazvirokwazvo isingakuvadzi. Products yaigadzirwa silicone rabha, husingakwanisi makemikari akawanda. Izvi zvinoita kuti zvinhu yakasiyana. Nokuti kupikisa zvinokonzerwa ozone, hydrogen peroxide, acids siyana uye alkalis, chicherwa mafuta, phenols uye alcohols.

mutambo

Sezvo kugadzirwa rabha silicone kupisa nemishonga? It chinoitwa paakarapa wemisanganiswa, murwiyo izvo ane rabha. Sezvo dzimwe zvinoriumba mu Formulations dzakadaro silicas anoshandiswa Somuenzaniso, carbon chena, Aerosil uye zvichingodaro. Mukuwedzera, musanganiswa kazhinji akawedzera zviripo uye dzimwe Excipients. Kazhinji, kuti vulcanization pasi zvinhu zvakadai Organic peroxides.

Mukuita kuti kubudisa silicone elastomer zvinhu kwakadaro kuumbwa, ine zvivako zvakawanda zvinobatsira. Heat nemishonga rabha rakasiyana nemamwe mhando yepamusoro uye upenyu basa refu. Munzvimbo dzakawanda, ehupfumi yakadaro inokosha. Mukuwedzera, silicone rabha inoshandiswa chero tembiricha ezvinhu.

Uyezve, imwe elastomer, iyo yakaumbwa mumakore okurapa nevasori, zviri zvachose vasiri chepfu uye inert kune zvipenyu zvakawanda kwendangariro. Uku kunoita kushandisa mashoko acho zvokurapa, uyewo zvokudya indasitiri.

zvinhu ehupfumi

Products dzakagadzirwa silicone rabha yakaisvonaka kukunda inodzokororwa tembiricha chokupfeka. Izvi zvinhu hazvigoni sterilized kamwe, achishandisa mhepo inopisa kana chiutsi.

Silicone rabha pepa rine pose, akapa vane vakaderera adhesion. Izvi zvinobvumira kuti ose zvinhu kuti mabhanzi kuti rinopfungaira, zvitarisiko uye coatings conveyors.

Pakati unhu silicone rabha vanofanira govera zvayo yakakwirira kuramba acids, alkalis, alcohols, uye asiri toxicity, zvakanaka zvemagetsi kuputira ehupfumi, kuramba operability pa + 400 ° C uye elasticity pa -100 ° C. Izvi zvinobvumira kushandiswa silicone rabha mumamiriro ezvinhu iwayo kuti tsika elastomers havangagoni kumira.

Unhu chisimbiso

Kupisa nemishonga silicone rabha rave rinoparadzirwa ave chisimbiso uye zvimwe zvinhu, uyewo membranes kuti chafariz kwechaunga. Asi handizvo zvose kushandisa mashoko aya. Silicone rabha rinowanzoshandiswa rakavhara unhu nokuda bhaira uye vira zvokushandisa, pagondobwe midziyo, apo pane yakakwirira chafariz mutoro uyewo kupomba hosipaipi. Panyaya iyi, mashoko ari nyore irreplaceable.

Uyewo rinoshandiswa sezvo huru mbishi zvinhu hwokubereka gaskets vanogona kumira zvakasimba chando kana kupisa. Uyewo, silicone rabha chinhu yakanaka zvinhu nokuda kwezvifananidzo zvaAtemisi thermally kugadzikana umbowo vamapoka chisimbiso pamusoro package.

Medicine uye Pharmaceutics

Nemhaka kumhedziso kuchengeteka, uye kwazvo zvemaziso zvivako zviri silicone rabha inoshandiswa mukurapa uye neindasitiri inogadzira mishonga kuumba nemaruva uye utsanana zvigadzirwa. Nekuti mashoko aya ari kugadzirwa pasina kuwedzera plasticizers, stabilizers nezvimwe zvinokuvadza yokuvirisa. Muenzaniso iyi inogona kushanda matoyi evana uye Pacifiers, anodyara, catheters, prostheses, rufimbi Masiki uye zvokurapa Yatanga Kuongorora.

zvigadzirwa zvose akagadzirwa nokupisa nemishonga chikafu giredhi silicone rabha, vakasiyana nevamwe kushaya chero munhuhwi, mukuru Utsanana, vasiri kugarisana pamwe Manyiminya pachena. Uyezve, mashoko haakwanisi kukonzera neutachiona. Product vanorichenesa, anokwanisa dzinga mvura kwete chete, asiwo guruva. Ivo husingakwanisi chafariz kunetseka. Izvi dzinovabvumira kakawanda sterilized with hot hwemvura kana kufashaira mvura.

Other mabhora ose chikumbiro

Silicone rabha inoshandiswa mumaindasitiri kugadzirwa. Uye kuvonga zvose ayo nemamwe ehupfumi. Izvi zvinhu raishandiswa Automotive indasitiri. Ikoko rinoshandiswa sezvo gaskets uye nezvisimbiso hunoita kubatana nevamwe zvikamu. Kunyanya kukosha anopiwa kuti kugona kwavo kutsungirira kugara UV mwaranzi, Anti Ndinoda uye mafuta siyana. Mukuwedzera, gasket inofanira kuva mukuru mwero kusakara nemishonga uye yakakwirira nesimba zvokuimba.

Chinodzivirira uye chinovhara waya elastomers vari zvinowanzoshandiswa zvemagetsi mapurani. Kazhinji, vari kubva ose zvinhu kwete chete nokuda kwezvipfuwo zvinangwa. Zvakagadzirwa silicone rabha netambo, izvo zvinoshandiswa maindasitiri zvokushandisa, midziyo yemagetsi uye yemagetsi, ayo kunoshanda zvakanaka hasha ezvinhu.
