Maitiro ekugadzira uye mashanu maitiro egirazi fiber

一、Girazi faibha kugadzira maitiro

Fibers girazi, inosimbisa Fibra de vidrio compuestauye simbi yokutsiva zvinhu.Iyo dhayamita yemonofilament inoverengeka mamicrons kusvika makumi maviri mamicrons, ayo akaenzana ne1/20-1/5 yebvudzi, uye imwe neimwe bundle ye fiber tambo inoumbwa nemazana kana kunyange zviuru zve monofilaments.

Fiberglass pre preg ine hunhu hwekusapisa, kushota, kupisa kupisa, kuvharidzira kwakanaka kwemazwi, kusimba kwesimba, kunaka kwemagetsi, etc. Iine huwandu hwakawanda hwekushandisa uye inoshandiswa zvakanyanya mukuvaka, mota, zvikepe, kemikari. mapaipi, njanji yekufambisa, simba remhepo uye mamwe minda Broad application tarisiro.

Kune marudzi maviri egirazi fiber kugadzira maitiro: maviri-nguva kuumba - crucible dhizaini nzira, imwe yekugadzira - dziva kiln yekudhirowa nzira.

Iyo crucible yekudhirowa nzira ine akawanda maitiro.Kutanga, iyo girazi raw material inonyungudutswa kuita mabhora egirazi pakupisa kwakanyanya, uyezve mabhora egirazi anonyungudutswa kechipiri, obva adhonzwa nekumhanya kukuru kugadzira.roving.Iyi nzira ine zvipingamupinyi zvakasiyana-siyana zvakadai sekushandiswa kwesimba guru, kusagadzikana kwekuumbwa kwemaitiro, uye kuderera kwekushanda kwevashandi, uye kunobviswa zvakanyanya nevagadziri vegirazi guru.

Iyo dziva kiln yekudhirowa nzira inonyungudutsa mbishi se pyrophyllite mumhinduro yegirazi muchoto, inobvisa mhepo inoputika uye inoiendesa kune ine porous bushing kuburikidza nemupassage, uye inoikwevera mugirazi fiber strand nekumhanya kwakanyanya.Iyo kini inogona kubatanidza mazana emabhushi kuburikidza nematanho akawanda ekugadzira panguva imwe chete.Iyi nzira iri nyore, inochengetedza simba uye inoderedza kushandiswa, yakagadzikana mukuumbwa, yakakwirira-inoshanda uye yakawanda-goho, uye yakanakira kugadzirwa kwakakura kuzere otomatiki.Yakave nzira yepasi rose yekugadzira.Fiberglass quoins inogadzirwa neichi chiitiko inoita inodarika 90% yepasi rose.

二、 Iwo mashanu maitiro egirazi fiber

1.Kuchengetedza uye kuchengetedzwa kwezvakatipoteredza, kuchengetedza hutano hwevashandi

Girazi faibha ine simba rakasimba rekusimba, haina kuunyana, anti-vulcanization, isina utsi, halogen-isina, isina chepfu, yakachena oxygen, isingabatike, uye yakanaka insulating zvivakwa.Mushure mekurapa nesilicone, kuchengetedzwa kwayo uye kushanda kwezvakatipoteredza kunogona kuvandudzwa.Kunyatso chengetedza hutano hwevanhu hwevashandi uye kuderedza kuitika kwezvirwere zvebasa.Kusiyana nezvigadzirwa zveasbestos, zvinokuvadza zvakanyanya kuvanhu uye nharaunda.

2.Excellent temperature resistance

Pamusoro pefiberglass thermal insulation ine zvese "organic groups" uye "inorganic zvimiro".Iyi yakakosha kuumbwa uye chimiro chemolecular inobvumira kuti ibatanidze zvimiro zve organic matter nebasa re inorganic matter.Kuenzaniswa nezvimwe zvinhu zvepolymer, inomira kunze kwekupisa kwayo kwepamusoro.Iyo silicon-oxygen (Si-O) chisungo ndicho chikuru cheni chimiro, uye chisungo chesimba cheCC bond i82.6 kcal / g uye simba rebhondi reSi-O bond i121 kcal / g mu silicone resin, saka kugadzikana kwekupisa kwakakwira, uye Iyo kemikari zvisungo zvemamorekuru hazviputsi kana kuparara pasi pekupisa kwakanyanya (kana kuratidzwa kwemwaranzi).Silicone haingodziviriri kune tembiricha yakakwira asiwo yakaderera tembiricha, uye inogona kushandiswa muhupamhi tembiricha renji.Iyo haichinji nekushisa, kungave mumakemikari kana emuviri-mechanicha zvinhu.

3.Anti-splash, kuchengetedzwa kwakawanda

Muindasitiri yekunyungudutsa, tembiricha yepakati muchoto chemagetsi yakakwira zvakanyanya, uye tembiricha yekupisa inogadzirwa nyore nyore (sezviri muindasitiri yemagetsi welding).Mushure mekutonhora uye kusimba, slag inoumba papombi kana tambo, iyo inoomesa rubber pamucheto wekunze wepombi kana tambo uye inokonzera brittle kuputsika.Zvakare, midziyo isina kudzivirirwa uye tambo dzinogona kukuvadzwa.Mushure mekushandisa akawanda silicone-yakavharwafiberglass sleeves, dziviriro dzakawanda dzekuchengetedza dzinogona kuwanikwa uye tembiricha yakanyunguduka yesimbi yakanyungudutswa, mhangura uye aluminium inogona kudzivirirwa zvinobudirira.splash mvura kudzivirira kukuvara kwetambo dzakatenderedza nemidziyo.

4. Kupisa kupisa, kuchengetedza simba, anti-radiation

Mumusangano wekushisa wepamusoro, mapaipi akawanda, mavharuvhu kana midziyo ine kupisa kwemukati kwakanyanya.Kutsva kana kurasikirwa nekupisa kunogona kuitika kana isina kufukidzwa nezvinhu zvinodzivirira.Fiberglass ine kugadzikana kurinani kwekupisa kupfuura zvimwe zvinhu zvepolymer, uye inopesana nemwaranzi uye kupisa kwekupisa, kudzivirira tsaona, kuderedza kushandiswa kwesimba uye kudzivirira kutamisa kwakananga kwekupisa kubva pakati mupombi kuenda kunzvimbo yakatenderedza.Zvakatipoteredza zvinopisa musangano, izvo zvinochengetedza mari yekutonhora.

5.Moisture-proof, mafuta-proof, weather-proof, kusvibisa-uchapupu, kurebesa hupenyu hwebasa remidziyo.

Girazi fiber ine kugadzikana kwemakemikari yakasimba.Silicone haigoni kuita nemafuta, mvura, asidi uye alkali nezvimwewo. Pakupisa kwe260 ° C, inogona kushandiswa kwenguva yakareba pasina kukwegura.Hupenyu hwesevhisi hwefiberglass isina mvuramunzvimbo yakasikwa inogona kusvika makumi emakore akawanda.Muchiitiko ichi, inogona kuchengetedza mapaipi, tambo uye midziyo kusvika pamwero mukuru uye kuwedzera zvakanyanya kushandiswa kwavo.
