Kodi pepala la mphira la silicone ndi chiyani?
Pepala la mphira la silicone ndi mphira wopangidwa kuchokera ku silikoni, polima wopangidwa ndi mayunitsi a siloxane. Ili ndi kukana kwambiri kutentha ndi nyengo, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo ma gaskets, seal, insulation, ndi mbale zosindikizira. Labala ya silicone imapezeka m'mitundu iwiri: pepala lolimba la mphira la silikoni ndi pepala la mphira lamadzimadzi. Rabara yolimba ya silikoni ndiyofala kwambiri ndipo imagwiritsidwa ntchito pazifukwa wamba. Rabara ya silikoni yamadzimadzi imagwiritsidwa ntchito nthawi zambiri pazachipatala chifukwa imakhala yosinthika komanso imakhalabe ndi mawonekedwe ake kuposa mphira wolimba wa silikoni. Mapepala a mphira a silicone amapezeka mumitundu yosiyanasiyana, kuphatikizapo yoyera ndi yakuda. Kuphatikiza pa utoto, pepala la mphira la silicone limabweranso m'makalasi osiyanasiyana. Mtundu wa zinthu zomwe zimagwiritsidwa ntchito popanga pepala la mphira la silikoni zimatsimikizira mtundu wake.
Kodi pepala la mphira la silicone limagwiritsidwa ntchito bwanji?
Pepala la mphira la silicone ndi mphira wopangidwa ndi silicon ndi mpweya. Itha kugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza zida zamagalimoto, zida zamankhwala, komanso kutchinjiriza magetsi. Imakhala ndi kukhazikika kwamafuta ambiri komanso kukana ozoni ndi zinthu zina zanyengo. Imakhalanso ndi magetsi abwino ndipo ingagwiritsidwe ntchito kumalo otsika kwambiri. Imalimbana bwino ndi nyengo ndi ozoni, imalimbananso ndi mankhwala ambiri, mafuta, ndi mafuta. Silicone mu rabara ya silikoni imatha kupirira kutentha mpaka 400 ° C. Rabara ya silicone ndi mphira wopangidwa ndi polymerization wa osakaniza a silicone opanda ma monomers. Chosakanizacho chikhoza kukhala chamadzimadzi kapena cholimba, ndipo mawonekedwe ambiri amakhala phala ndi ufa. Rabara ya silicone imapangidwa ndi polymerization ya osakaniza a monomers, monga trimethylsiloxysilicate ndi dimethylpolysiloxane. The chifukwa kupanga mphira ndi viscous madzi (nthawi zambiri mu phala mawonekedwe) kapena olimba, nthawi zambiri granules.
Ubwino wa pepala la mphira la silicone
Chipepala cha mphira cha silicone ndi mtundu wa zinthu za polima zomwe zimakhala ndi thupi komanso mankhwala. Imakhala ndi kukana bwino kutentha kwambiri, kutentha pang'ono, ozoni ndi nyengo. Ilinso ndi kutchinjiriza kwamagetsi kwabwino komanso kuchepa kwamoto, chakudya chotetezeka, chowongolera, chosagwira mafuta, chosavuta kudula. Silicone mphira pepala chimagwiritsidwa ntchito mu ndege, zamlengalenga, zamagetsi, zitsulo, makina, mayendedwe ndi mafakitale ena. Pepala la mphira la silicone limagwiritsidwanso ntchito m'makampani amagetsi ndipo lili ndi ntchito zambiri. Imagwiritsidwa ntchito pazida zosiyanasiyana zamagetsi monga zowonetsera pagulu lathyathyathya, ma board ozungulira osindikizidwa, zoteteza ma surge, zingwe ndi ma waya, ma casing a zida zamagetsi. Chipepala cha mphira cha silicone chimagwiritsidwanso ntchito m'mafakitale osiyanasiyana monga zomangamanga, magalimoto, mapaipi, magetsi ndi zamagetsi. Pepala la mphira la silicone lili ndi ntchito zambiri pantchito yomanga komwe imagwiritsidwa ntchito popanga mapaipi ndi machubu. Mapepala a mphira a silicone akhoza kukhala amitundu yosiyanasiyana, monga wakuda ndi woyera, wachikasu, wobiriwira, wofiira ndi wabuluu. Mapepala a mphira a silicone angakhalenso oyera kapena omveka bwino. Pepala la mphira la silicone ndi pepala lopangidwa ndi mphira lomwe limapangidwa ndi silikoni, polima wopangidwa ndi s-Si-Rings. Nkhaniyi ili ndi coefficient yochepa ya kukangana ndi kukana bwino kutentha kwambiri. Ilinso yopanda poizoni komanso yopanda mphamvu, yomwe imapangitsa kuti ikhale yabwino pakugwiritsa ntchito chakudya.
Zoyipa za pepala la mphira la silicone
Pepala la mphira la silicone ndi pepala lopangidwa ndi mphira lomwe limapangidwa ndi silikoni, polima yopangidwa ndi silicon ndi mpweya. Zili ndi ubwino wambiri kuposa zipangizo zina, koma pali zovuta zina zogwiritsira ntchito mapepala a mphira a silicone.
Choyipa chimodzi chogwiritsa ntchito mphira wa silicone ndi mtengo wake. Zovala za mphira za silicone zimatha kuwirikiza kawiri kuposa mitundu ina ya rabala.
Chachiwiri n’chakuti chikhoza kukhala chophwanyika ndipo chikhoza kung’ambika ngati sichigwiridwa bwino kapena kugwetsedwa. Ndipo chomaliza ndi chakuti mapepala a mphira a silicone sagonjetsedwa ndi kutentha ndi mankhwala, koma akhoza kuonongeka mosavuta ndi abrasion ndi zokopa pamwamba.
athu wopanga silikoni mphira mankhwala opanga ali ndi mapepala otsekedwa a mphira wa silicone, Tsegulani mapepala a mphira a silicone, insulation silicone mphira mapepala, mapepala apamwamba a mphira a siliconendipo thermally conductive silikoni mphira mphasa, mapepala opangira mphira a silicone opangira magetsi, extrusion silikoni mphira mankhwala, kudula kukula kwa mphira wa silicone. Ngati muli ndi mafunso kapena zosowa, chonde titumizireni kwaulere.
