Patinoona zvigadzirwa zvakagadzirwa nefiberglass, tinowanzo cherechedza chitarisiko chadzo uye mashandisirwo adzo, asi kashoma kufunga nezve: Chii chiri mukati meshinda iyi nhema kana chena? Ndiwo chaiwo magadzirirwo madiki aya asingaonekwe anopa fiberglass hunhu hwayo hwakasiyana, hwakadai sekusimba kwakanyanya, kuramba kupisa kwakanyanya, uye kuramba ngura. Nhasi, tichaongorora "nyika yemukati" yefiberglass kuti tiburitse zvakavanzika zvechimiro chayo.
Nheyo yeMicroscopic: "Kurongeka Kusina Kurongeka" paAtomic Level
Kubva pamaonero eatomu, chinhu chikuru che fiberglass isilicon dioxide (inowanzova 50%-70% nehuremu), nezvimwe zvinhu zvakaita secalcium oxide, magnesium oxide, uye aluminium oxide zvichiwedzerwa kugadzirisa hunhu hwayo. Kurongeka kwemaatomu aya kunosarudza hunhu hwe fiberglass.
Kusiyana ne "kurongeka kwenguva refu" kwemaatomu muzvinhu zvekristaro (zvakadai sesimbi kana makristaro equartz), kurongeka kwemaatomu mufiberglass kunoratidza"kurongeka kwenguva pfupi, kusagadzikana kwenguva refu."Zvichitaurwa zviri nyore, munzvimbo yemunharaunda (iri mukati memaatomu mashoma), atomu yega yega yesilicon inobatana nemaatomu mana eokisijeni, zvichiita piramidhi."silica tetrahedron"chimiro. Kurongeka uku kwenzvimbo kwakarongwa. Zvisinei, pamwero mukuru, idzi silica tetrahedra hadziumbi lattice inodzokororwa nguva dzose semukristaro. Pane kudaro, dzakabatana zvisina kurongeka uye dzakarongwa nenzira isina kurongeka, zvakafanana nemurwi wemabhurukwa ekuvaka akaunganidzwa zvisina kurongeka, achigadzira chimiro chegirazi chisina chimiro.
Chimiro ichi chisina chimiro ndechimwe chezvinhu zvikuru zvakasiyana pakatifiberglassnegirazi rakajairika. Munguva yekutonhodza girazi rakajairika, maatomu ane nguva yakakwana yekuumba makristaro madiki, akarongwa munharaunda, izvo zvinoita kuti anyanye kuputsika. Kusiyana neizvi, fiberglass inogadzirwa nekutambanudza nekutonhodza girazi rakanyungudutswa nekukurumidza. Maatomu haana nguva yekuzvironga zvakarongeka uye "anoomeswa nechando" mumamiriro aya asina kurongeka, asina chimiro. Izvi zvinoderedza zvikanganiso pamiganhu yekristaro, zvichibvumira fiber kuchengetedza hunhu hwegirazi uku ichiwana kusimba kuri nani uye simba rekudhonza.
Maumbirwo eMonofilament: Chinhu Chinofanana Kubva ku "Ganda" Kuenda ku "Mukati"
Fiberglass yatinoona inoumbwa nezvinhu zvakawandamonofilaments, asi monofilament yega yega iyuniti yakakwana yekuvaka pachayo. Monofilament inowanzova nedhayamita ye5-20 micrometers (inenge 1/5 kusvika 1/2 dhayamita yebvudzi remunhu). Maumbirwo ayo akafanana."Chimiro chakasimba che cylindrical"pasina kuumbwa kwakajeka. Zvisinei, kubva pamaonero ekugoverwa kwezvikamu zvisingaonekwi nemaikorosikopu, pane musiyano mudiki we "ganda-pakati".
Munguva yekudhirowa, sezvo girazi rakanyungudutswa richiburitswa kubva mumaburi madiki espinneret, pamusoro payo painotonhora nekukurumidza kana yabata mhepo, zvichiita kuti pave nechinhu chakatetepa."Ganda"rukoko (runenge 0.1-0.5 micrometers ukobvu). Rukoko urwu rweganda runotonhora nekukurumidza kupfuura mukati"Musimboti."Nekuda kweizvozvo, huwandu hwesilicon dioxide muganda hwakakwira zvishoma pane huri pakati peganda, uye kurongeka kwemaatomu kwakasimba uye kusina kukwana. Musiyano uyu mudiki mukugadzirwa uye maumbirwo unoita kuti pamusoro pemonofilament pave nesimba mukuoma uye kuramba ngura kupfuura pakati peganda. Zvinoderedzawo mukana wekutsemuka kwenzvimbo - kutadza kwezvinhu kunowanzotanga nekusakwana kwenzvimbo, uye ganda iri rakakora rinoshanda se "goko" rinodzivirira monofilament.
