Ma Silicones ndi gulu losunthika la ma polima omwe amabwera m'njira zosiyanasiyana, omwe amapereka kuthekera kwakukulu kosintha makonda kuti akwaniritse zofunikira zachipatala ndi zakuthambo.Makhalidwe awo amawathandiza kugwira ntchito zosiyanasiyana, monga kusindikiza, kuthira mafuta, ndi kukwaniritsa ntchito zina zambiri.
Kusinthasintha kwa silicone kumabwera chifukwa cha mawonekedwe ake apadera komanso amakina, zomwe zimapangitsa kuti ikhale yamtengo wapatali m'mafakitale osiyanasiyana.Nkhaniyi ifotokoza za Zisanu zomwe wamba komansozothandiza za siliconendi kufufuzamagulu anayi oyambirirazinthu za silikoni.Kuphatikiza apo, tikambirana njira zosiyanasiyana zopangira ndikufotokozera chifukwa chomwe silicone ingakhale chisankho choyenera pazosowa zanu zenizeni.
1.Silicones samachitapo kanthu pamankhwala ndipo amawonetsa kusayenda bwino kwamafuta.
Kuthyola unyolo wa silicon-oxygen mu mamolekyu a silikoni kumafuna mphamvu zambiri.Chifukwa cha kukana kwakukulu kwa mamolekyu a silikoni kuti asinthe, mankhwala ambiri alibe mphamvu zokwanira kuti apangitse kusintha kwamankhwala.Zotsatira zake, silikoni nthawi zambiri imakhala yopanda mphamvu.Zomangira zokhazikika mu silicone ndizomwe zimayambitsa zambiri zabwino zake.
Ma silicones nthawi zambiri amawonetsa kutsika kwamafuta chifukwa cha kapangidwe kake ka maselo, zomwe zimalepheretsa kufalikira kwa kutentha kwapakati pakati pa mamolekyu.Ngakhale malowa atha kukhala opindulitsa pazinthu zina, monga ma oven mitts, zitha kukhala zolepheretsa m'malo ena pomwe kutentha koyenera ndikofunikira.Kuti athane ndi vutoli, zodzaza ndi ma thermally conductive zitha kuphatikizidwa mu kapangidwe ka silicone kuti apititse patsogolo kusamutsa kutentha ndikukwaniritsa zofunikira pakugwiritsa ntchito.
2.Silicone ili ndi kawopsedwe kakang'ono
Silicone nthawi zambiri imawonedwa ngati chinthu chosavulaza thanzi la munthu.Mitundu yonse ya silicone ya chakudya komanso yachipatala yavomerezedwa ndi FDA kuti igwiritsidwe ntchito pokhudzana ndi chakudya komanso kuyika kwanthawi yayitali m'thupi la munthu.Komabe, ndikofunikira kutsatira malangizo a wopanga mukamagwiritsa ntchito zinthu za silicone kuti muwonetsetse chitetezo.
3.Silicone ili ndi kuthekera kwakukulu kothamangitsa madzi
Silicone ili ndi mtundu wapadera womwe umadziwika kuti hydrophobicity, kutanthauza kuti ili ndi mphamvu yothamangitsa madzi.Izi zimatheka chifukwa cha magulu a methyl omwe amamangiriridwa ku tcheni cha silicon-oxygen polymer, chomwe sichikhala polar mwachilengedwe ndipo alibe mgwirizano wa mamolekyu amadzi.Zotsatira zake, mamolekyu amadzi sangathe kufalikira ndikulowa pamwamba pa silikoni, ndipo m'malo mwake, amamangirira ndikugudubuza.Chida chodabwitsachi choletsa madzi, kuphatikiza luso la silikoni kupanga chomata cholimba chokhala ndi malo osiyanasiyana, chimapangitsa kuti zinthu zomata za silikoni zikhale zogwira mtima kwambiri, zokhala ndi zisindikizo zomwe zimatha kupirira kwazaka zambiri.
4.Silicone imatha kukhala ngati insulator ndi conductor wamagetsi.
Rabara ya silicone nthawi zambiri imagwira ntchito ngati insulator chifukwa chosowa ma elekitironi aulere kuti athe kunyamula.Ubwinowu ndiwopindulitsa kwambiri pazogwiritsa ntchito zosiyanasiyana, makamaka zachipatala komwe kutsekemera ndikofunikira.Komabe, silikoni imatha kusinthidwa kuti ipereke magetsi kumlingo wakutiwakuti pakugwiritsa ntchito ngati ma gaskets ndi zishango zokhazikika.Kusintha uku kumaphatikizapo kuphatikizira zodzaza ngati kaboni, siliva, kapena zinthu zina zowongolera muzinthu za silikoni.
5.Silicone ili ndi kukana kwakukulu kwa organic compound solvents
Silicone nthawi zambiri imatha kupirira kukhudzana ndi mankhwala ambiri chifukwa cha mawonekedwe ake osagwira ntchito komanso mphamvu zochepa zapamtunda.Komabe, zinthu zingapo zosankhidwa, makamaka sulfuric ndi hydrofluoric acid, zimatha kuvulaza ma silicones.Ponena za mankhwala opangidwa ndi organic omwe amatha kugwira ntchito ngati sol, ma silicones amatha kuwonongeka pambuyo polumikizana kwanthawi yayitali ndi zinthu monga toluene, mineral spirits, petulo, ndi carbon tetrachloride.
Zothandiza za silicone
Kusinthasintha kwa silicone kumapangitsa kukhala chinthu chofunikira m'mafakitale osiyanasiyana, kuphatikiza:
* Zagalimoto: Kutentha kwambiri kwa silicone ndi kulimba kwake kumapangitsa kuti ikhale chigawo choyenera pakupanga magalimoto.
* Zamlengalenga: Zida za silicone zotchinjiriza komanso kukana kutentha kwambiri zimapangitsa kuti ikhale yofunika kwambiri popanga ndege.
* Zovala: Zovala zopangidwa ndi silika zimapereka chithumwa chokhazikika komanso chosagwira madzi pamalo osiyanasiyana.
* Zomangamanga: Zisindikizo za silicon ndi zomatira zimagwiritsidwa ntchito pomanga kuti zitsimikizire kuti malo olumikizirana mpweya komanso osalowa madzi.
* Chophika: Silicone imalimbana ndi kutentha imapangitsa kuti ikhale yabwino kwambiri popangira zophikira, monga mphasa zophikira ndi ma spatula.
* Mafuta: Mafuta a silikoni amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo injini zamagalimoto, makina opangira mafakitale, ndi zida zapakhomo.
* Zamagetsi: Silicone imakhala yofunikira kwambiri pazida zamagetsi, monga makompyuta, mafoni am'manja, ndi ma TV.
* Kupanga nkhungu: Kusinthasintha komanso kulondola kwa silicone kumapangitsa kuti ikhale chinthu choyenera kupanga zisankho zamitundu yosiyanasiyana, kuphatikiza zida zamankhwala ndi zida zamagalimoto.
* Mankhwala ndi Opaleshoni Yodzikongoletsa: Kugwirizana kwa silicone ndi kusinthasintha kwake kumapangitsa kuti ikhale yofunika kwambiri pakupanga ma implants, ma prosthetics, ndi opareshoni yodzikongoletsa.
* Zoseweretsa ndi zokonda: Kusinthasintha komanso kulimba kwa silicone kumapangitsa kukhala chinthu chodziwika bwino popanga zoseweretsa, masewera, ndi zinthu zina zosangalatsa.
Mitundu Yoyamba ya Silicone
Mitundu inayi yayikulu kapena mitundu yazinthu za silikoni zalembedwa pansipa:
• Room-temperature Vulcanizing (RTV): Ma silicones awa amachiritsa, kapena kuyika, pa kutentha kwa chipinda.Kawirikawiri amagwiritsidwa ntchito kusindikiza ndi kumanga.Mapangidwe a RTV-1 amayamba kuchiritsa nthawi yomweyo akakumana ndi chinyezi mumlengalenga.Ma silicones a RTV-2 amabwera ngati mankhwala awiri osiyana omwe wogwiritsa ntchito mapeto ayenera kuphatikiza kuti ayambe kuchiritsa.Izi zimapangitsa RTV-2 kukhala yosinthika kwambiri pamagwiritsidwe ntchito ngati kuumba ndi zokutira.
• Liquid Silicone Rubber (LSR): LSR ili ndi dongosolo la zigawo ziwiri, ndi zigawo ziwiri zomwe zimagwirizanitsidwa panthawi yogwiritsidwa ntchito.Nthawi zambiri amachiritsidwa pa kutentha kwakukulu, pogwiritsa ntchito chothandizira cha platinamu.Njira zowumba zomwe zimagwiritsidwa ntchito komanso mawonekedwe omaliza a LSR amatha kusinthika kumitundu yambiri yamagwiritsidwe.
• Fluorosilicone Rubber (FSR): Mamolekyu a FSR amakhala ndi mayunitsi obwerezabwereza a silicon-oxygen backbone ndi malo ena ogwirizanitsa omwe amakhala ndi magulu ena a mamolekyu (magulu a methyl ndi fluoroalkyl).Izi zimapatsa zinthuzo kukana bwino kwamafuta ndi mafuta.FSR ndiyotchuka posindikiza mapulogalamu pamayendedwe apandege.
• High-Consistency Rubber (HCR): HCR, yomwe imadziwikanso kuti "raba yochizira kutentha," imakhala ndi unyolo wapamwamba kwambiri wa silicone polima.Zopangira zimatha kukhala ndi ma fillers ndi zowonjezera kuti mupeze mawonekedwe omwe mukufuna.Nthawi zambiri amaperekedwa mu mawonekedwe ochiritsidwa pang'ono, oti "gummy" omwe amakulungidwa mu pepala lochindikala.Ndi yabwino kugwiritsidwa ntchito pazida zina zachipatala, kuphatikiza machubu, mabuloni, ndi mapepala.
Silicone imabwera m'malo osiyanasiyana, kuyambira madzi mpaka olimba.Customer amatha kusintha makonda amtundu wa silicone molingana ndi mawonekedwe azinthu kuti agwirizane ndi zomwe zida zomaliza.
Chidule
Nkhaniyi idawunikiranso za 5 za silikoni, idawunikiranso zamankhwala ake komanso mawonekedwe ake, ndikuwunika mitundu yosiyanasiyana yomwe ingatengedwe mumakampani.
Kuti mudziwe zambiri za silicone,chonde titumizireni.
