Silikoni mphira: Kukonzekera, katundu ndi Mapulogalamu

Silikoni mphira zaposachedwapa kukhala chuma wotchuka kwambiri. Kulibe vuto lililonse mwamtheradi. Zamgululi zopangidwa kuchokera mphira silikoni, ndi kugonjetsedwa ndi mankhwala ambiri. Izi zimapangitsa nkhani yapadera. Chifukwa amatha kulimbana zotsatira za Mpweya umene, hydrogen peroxide, zidulo zosiyanasiyana ndi alkalis, mchere mafuta, phenols ndi alcohols.

phwando

Monga chopangidwa mphira silikoni kutentha zosagwira? Linapangidwa ndi kuchiritsa zosakaniza, zikuchokera amene ali mphira a. Monga zigawo zina formulations ngati silicas ntchito Mwachitsanzo, woyera mpweya, Aerosil ndi zina zotero. Komanso, osakaniza nthawi zambiri anawonjezera sayansi ndi zina excipients. Nthawi zambiri, vulcanization phunziro zinthu monga peroxides organic.

Mu ndondomeko yopangira chotero silikoni elastomer zinthu aumbike, amene ali katundu ambiri opindulitsa. Kutentha zosagwira mphira ndi osiyana ndi mitundu ina ya mkulu khalidwe ndi moyo wautali utumiki. M'madera ambiri, katundu ngati ili yofunika kwambiri. Komanso, silikoni mphira ntchito pafupifupi zinthu aliyense kutentha.

Kuwonjezera apo, elastomer, amene anapanga pa nthumwi akuchiritsa, izo mwamtheradi si poizoni ndi inert kuti njira zambiri kwachilengedwenso. khalidwe Ichi chizathandiza ntchito mfundo za mankhwala, komanso makampani chakudya.

katundu zakuthupi

Zamgululi zopangidwa silikoni mphira chabwino kupirira mobwerezabwereza kutentha kukhudzana. Nkhanizi sangathe chosawilitsidwa kamodzi, pogwiritsa ntchito mpweya otentha kapena nthunzi.

Silikoni mphira pepala ali pamwamba, malinga ndi guluu wolimba otsika. Zimenezi zimathandiza kuti mitundu yonse ya zinthu kuti masikono chifukwa anagubuduza, akalumikidzidwa ndi zokutira conveyors.

Makhalidwe a mphira silikoni ayenera kuonetsetsa kukana ake okwezeka zidulo, alkalis, alcohols, ndipo sanali kawopsedwe, katundu wabwino kutchinjiriza magetsi, kukhalabe operability pa + 400 ° C ndi elasticity pa -100 ° C. Ichi chizathandiza ntchito mphira silikoni m'zochitika anthu kuti elastomers mwambo chabe sungakhale.

chisindikizo khalidwe

The kutentha zosagwira silikoni mphira wakhala ofalitsidwa monga kusindikiza ndi zinthu zina, komanso zimagwira ntchito zosiyanasiyana chifukwa cha khamu matenthedwe. Koma si ntchito zonse za nkhaniyi. Silikoni mphira kawirikawiri amagwiritsidwa ntchito kusindikiza khalidwe kwa kukatentha ndi ng'anjo zida, zitsulo za zipangizo, pamene pali mkulu matenthedwe katundu komanso ikukoka payipi. Pankhaniyi, nkhani imangokhala irreplaceable.

Ndiponso ntchito monga chuma chachikulu yaiwisi yopangira gaskets kuti amatha kupirira chisanu chaukali kapena kutentha. Komanso, silikoni mphira ndi nkhani yabwino kupanga maziko thermally khola kwa mayunitsi a kusindikiza phukusi la.

Medicine ndi Pharmaceutics

Ndiyamika chitetezo mtheradi, ndipo kwambiri katundu makina a mphira silikoni ntchito mankhwala ndi malonda mankhwala kulenga nurseries ndi mankhwala ukhondo. Chifukwa nkhaniyi amapangidwa popanda Kuwonjezera plasticizers, stabilizers ndi zina zina zoipa. Chitsanzo pa nkhaniyi atha kutumikira ngati zidole ana ndi pacifiers, amadzala, catheters, ziwalo, mankhwala ochititsa masks ndi probes zachipatala.

Zonsezi ndi opangidwa silikoni mphira kutentha zosagwira chakudya kalasi, wosiyana zina kupanda zofukiza uliwonse, mkulu ukhondo, thupi ngakhale ndi chilungamo kuwala. Komanso, nkhani ndi kungoti amalephera chifukwa thupi lawo siligwirizana. Mankhwala aisadza, amatha kubweza osati madzi, komanso fumbi. Iwo kugonjetsedwa ndi nkhawa matenthedwe. Zimenezi zimawathandiza mobwerezabwereza chosawilitsidwa ndi nthunzi otentha kapena madzi otentha.

muzochitika zina za ntchito

Silikoni mphira ntchito mafakitale. Ndipo mathokozo onse katundu yake yapadera. Nkhanizi zinali kugwiritsidwa ntchito ku makampani magalimoto. Pamenepo ntchito ngati gaskets ndi zisindikizo moti kugwirizana kupeza mbali. zofunika kwambiri wapatsidwa ndi luso kupirira kukhudzana UV cheza, odana ndi amaundana ndi mafuta zosiyanasiyana. Komanso, gasket ayenera mlingo mkulu wa avale kukana ndi mkulu mawotchi mphamvu.

Chimateteza ndi chingwe elastomers ankagwiritsa ntchito zomangamanga magetsi. Monga ulamuliro, iwo anapangidwa kuchokera mitundu yonse ya mankhwala osati zolinga za m'banja. Zopangidwa silikoni zingwe labala, amene ntchito zipangizo mafakitale, zipangizo zamagetsi ndi zipangizo mphamvu ntchito mu malo mwachilungamo aukali.
