The ndondomeko kupanga ndi makhalidwe asanu galasi CHIKWANGWANI

一、Glass fiber kupanga ndondomeko

Fiber glass, Fibra de vidrio compuesta yolimbikitsandi chuma m'malo mwachitsulo.The awiri a monofilament ndi ma microns angapo kwa microns makumi awiri, omwe ndi ofanana ndi 1/20-1/5 wa tsitsi, ndipo aliyense mtolo wa CHIKWANGWANI zingwe wapangidwa mazana kapena masauzande a monofilaments.

Fiberglass preg ili ndi mawonekedwe osayaka, kukana dzimbiri, kutsekereza kutentha, kutsekereza mawu abwino, kulimba kwamphamvu, kutsekemera kwamagetsi, ndi zina zambiri. Ili ndi ntchito zambiri ndipo imagwiritsidwa ntchito kwambiri pomanga, magalimoto, zombo, mankhwala. mapaipi, mayendedwe a njanji, mphamvu yamphepo ndi madera ena Kuyembekeza kogwiritsa ntchito kwakukulu.

Pali mitundu iwiri yopangira magalasi opangira magalasi: kupanga kawiri - njira yojambulira crucible, imodzi yopangira - njira yojambulira dziwe.

Njira yojambula crucible ili ndi njira zambiri.Choyamba, galasi zopangira zimasungunuka mu mipira ya galasi pa kutentha kwakukulu, ndiyeno mipira ya galasi imasungunuka kachiwiri, kenako imakokedwa pa liwiro lalikulu kuti ipange.kuyendayenda.Izi zimakhala ndi zovuta zosiyanasiyana monga kugwiritsa ntchito mphamvu zambiri, kuumba kosakhazikika, komanso kutsika kwa ntchito, ndipo zimathetsedwa ndi opanga magalasi akuluakulu.

Njira yojambulira dziwe lamadzi amasungunula zinthu zopangira monga pyrophyllite mu njira yamagalasi mu uvuni, imachotsa thovu la mpweya ndikulipititsa kumalo otsetsereka podutsa ndimeyi, ndikuchikokera mu chingwe cha galasi pa liwiro lalikulu.Mng'anjoyo imatha kulumikiza mazana a tchire kudzera munjira zingapo kuti apange nthawi imodzi.Njirayi ndi yosavuta, yopulumutsa mphamvu komanso yochepetsera, yokhazikika pakuumba, yogwira ntchito kwambiri komanso yokolola zambiri, ndipo imakhala yabwino pakupanga kwakukulu kokwanira.Yakhala njira yopangira zinthu padziko lonse lapansi.Ma fiberglass quoins opangidwa ndi njirayi amapitilira 90% yazotulutsa padziko lonse lapansi.

二、 Makhalidwe asanu a galasi CHIKWANGWANI

1.Kuteteza ndi kuteteza chilengedwe, kuteteza thanzi la ogwira ntchito

Ulusi wagalasi uli ndi mphamvu zolimba zolimba, zopanda makwinya, zotsutsana ndi vulcanization, zopanda utsi, zopanda halogen, zopanda poizoni, okosijeni wangwiro, zosayaka, komanso zoteteza bwino.Pambuyo kuchiritsa ndi silikoni, chitetezo chake ndi ntchito zachilengedwe zitha kupititsidwa patsogolo.Kuteteza moyenera thanzi la anthu ogwira ntchito ndikuchepetsa kuchitika kwa matenda a ntchito.Mosiyana ndi zinthu za asibesitosi, zimakhala zovulaza kwambiri kwa anthu komanso chilengedwe.

2.Kukana kutentha kwabwino

Pamwamba pafiberglass kutenthetsa kutentha lili ndi "magulu achilengedwe" ndi "zomangamanga".Kapangidwe kapadera kameneka ndi kapangidwe ka mamolekyu kamalola kuti kaphatikize zinthu za organic ndi ntchito ya zinthu zopanda organic.Poyerekeza ndi zida zina za polima, zimadziwikiratu chifukwa cha kukana kwake kutentha kwambiri.Chomangira cha silicon-oksijeni (Si-O) ndicho chomangira chachikulu cha unyolo, ndipo mphamvu yomangira ya CC bond ndi 82.6 kcal / g ndipo mphamvu ya mgwirizano wa Si-O ndi 121 kcal / g mu utomoni wa silikoni, kotero Kukhazikika kwamafuta ndikwambiri, ndipo The Chemical bond of molecules samasweka kapena kusweka pansi pa kutentha kwakukulu (kapena kuwonekera kwa radiation).Silicone sikuti imalimbana ndi kutentha kwakukulu komanso kutentha kochepa, ndipo ingagwiritsidwe ntchito pa kutentha kwakukulu.Sisintha ndi kutentha, kaya ndi mankhwala kapena thupi-makina katundu.

3.Anti-splash, chitetezo chambiri

M'makampani osungunula, kutentha kwa sing'anga mu ng'anjo yamagetsi ndikokwera kwambiri, ndipo ma spatters otentha amapangidwa mosavuta (monga momwe amapangira magetsi).Pambuyo pozizira ndi kulimbitsa, slag amapanga pa chitoliro kapena chingwe, chomwe chimaumitsa mphira pamtunda wakunja wa chitoliro kapena chingwe ndikuyambitsa kuphulika kwa brittle.Kenako, zida zosatetezedwa ndi zingwe zimatha kuwonongeka.Pambuyo ntchito angapo silikoni TACHIMATAmagalasi a fiberglass manja, chitetezo chambiri chikhoza kutheka ndipo kutentha kwapamwamba kwachitsulo chosungunuka, mkuwa ndi aluminiyumu kumatha kupewedwa bwino.kuwaza madzi kupewa kuwonongeka kwa zingwe zozungulira ndi zida.

4. Kutentha kwa kutentha, kupulumutsa mphamvu, anti-radiation

Mu msonkhano wotentha kwambiri, mapaipi ambiri, ma valve kapena zipangizo zimakhala ndi kutentha kwapakati.Kupsa kapena kutaya kutentha kumatha kuchitika ngati sikunaphimbidwe ndi zinthu zoteteza.Fiberglass imakhala ndi kukhazikika kwamafuta kuposa zida zina za polima, ndipo imalimbana ndi ma radiation ndi kutchinjiriza kwamafuta, kuteteza ngozi, kuchepetsa kugwiritsa ntchito mphamvu ndikuletsa kusamutsa kwachindunji kwa kutentha kuchokera pakatikati pa chitoliro kupita kumadera ozungulira.Chilengedwe chimatenthetsa msonkhano, zomwe zimapulumutsa ndalama zoziziritsa.

5.Umboni wonyezimira, wosapaka mafuta, sugwirizana ndi nyengo, utsimikizo woipitsa, umatalikitsa moyo wautumiki wa zida

Ulusi wagalasi uli ndi kukhazikika kwamphamvu kwamankhwala.Silicone sichidzakhudzidwa ndi mafuta, madzi, asidi ndi alkali etc. Pa kutentha kwa 260 ° C, ingagwiritsidwe ntchito kwa nthawi yaitali popanda kukalamba.Moyo wautumiki wa fiberglass yopanda madzim'chilengedwe akhoza kufika zaka makumi angapo.Pankhaniyi, imatha kuteteza mapaipi, zingwe ndi zida kwambiri ndikutalikitsa ntchito yawo.
