Fiberglass ine zvakanakira zvakawanda zvakaita sekusimba kwakanyanya uye huremu hwakareruka, kuramba ngura, kuramba kupisa kwakanyanya, uye kushanda zvakanaka kwekudzivirira magetsi. Ndiyo imwe yezvinhu zvinoshandiswa zvakanyanya. Panguva imwe chete, China ndiyo zvakare inogadzira fiberglass yakawanda pasi rose.
1. Chii chinonzi fiberglass?
Fiberglass chinhu chisina kugadzirwa nesimbi chisina kugadzirwa chine simba rakanaka. Chicherwa chechisikigo chine silica sechigadzirwa chikuru, chichiwedzera simbi chaiyo ine oxide mineral. Mushure mekusanganisa zvakaenzana, inonyungudutswa pakupisa kwakanyanya, uye girazi rakanyungudutswa rinoyerera nepaburi rinobuda. , pasi pesimba rekudhonza nekukurumidza, rinokweverwa uye rinotonhodzwa nekukurumidza uye rinosimba kuita fibers dzakatetepa kwazvo.
Upamhi hwefiberglass monofilament hunotangira pama micron mashoma kusvika kuma micron makumi maviri, izvo zvakaenzana ne 1/20-1/5 yebvudzi. Boka rega rega refiber tambo rinoumbwa nemazana kana kunyange zviuru zve monofilaments.
Hunhu hwekutanga hwe fiberglass:
Chitarisiko chacho chakaita sedenderedzwa rine pamusoro wakatsetseka, chikamu chakaenzana chakaita denderedzwa rakakwana, uye chikamu chakabatana chakatenderera chine simba rakasimba rekutakura mutoro; kuramba kwegasi nemvura kudiki, asi nzvimbo yakatsetseka inoita kuti simba rekubatana kwefiber rive diki, izvo zvisingakodzeri kusanganiswa ne resin; huwandu hwacho hunowanzova 2.50-2.70 g/cm3, zvinonyanya kuenderana nekuumbwa kwegirazi; simba rekudhonza rakakwirira kupfuura mamwe mafiber echisikigo nemafiber ekugadzira; zvinhu zvinoputsika, kureba kwaro pakuputsika kudiki kwazvo; kuramba mvura uye kuramba acid zviri nani, nepo kuramba alkali kwakaderera. Musiyano.
2. Kupatsanurwa kwefaibhagirazi
Kubva pakurongwa kwehurefu, inogona kukamurwa kuita fiberglass inoenderera mberi, fiberglass pfupi (fiberglass yakareba) uye fiberglass refu (LFT).
3. Kushandiswa kwefiberglass
Fiberglass ine simba guru rekudhonza, ine modulus yakakura yekupfava, haibatike, haibatike nemakemikari, haina mvura yakawanda, uye ine mashandiro akanaka ekugadzirisa. , inoshandiswa zvakanyanya muminda yakasiyana-siyana.
Firiji yekunze yakakamurwa kuita zvikamu zvina zvichienderana nekushandiswa kwechigadzirwa: zvinhu zvinosimbisa zvepurasitiki yekusimbisa thermosetting yakasimbiswa, zvinhu zvinosimbisa fiberglass zvethermoplastics, zvinhu zvinosimbisa simende gypsum, zvinhu zvemachira zvefiberglass, izvo zvinhu zvinosimbisa zvinosvika 70-75%, zvinhu zvemachira zvefiberglass zvinosvika 25-30%. Kubva pamaonero ekushomeka kwemvura, zvivakwa zvine 38% (kusanganisira mapaipi, kubvisa munyu mumvura yegungwa, kudziya kwemba uye kudzivirira mvura, kuchengetedza mvura, nezvimwewo), kutakurwa kunoita 27-28% (mayacht, mota, njanji dzinomhanya zvakanyanya, nezvimwewo), uye zvemagetsi zvinoita 17%.
Muchidimbu, minda yekushandisa fiberglass inowanzo sanganisira zvekufambisa, zvekuvaka, indasitiri yemagetsi, indasitiri yemichina, indasitiri yepetrochemical, tsika dzekuzorora uye tekinoroji yekudzivirira nyika.
