Fiber yegirazi ine hunhu hwakanaka uye inoshandiswa zvakanyanya muminda yakawanda. Ichinhu chisina kugadzirwa nesimbi chinogona kutsiva simbi. Nekuda kwekubudirira kwayo, makambani makuru efiber yegirazi ari kutarisa pakutsvaga mashandiro epamusoro uye kugadzirisa mashandiro efiber yegirazi.
1 Tsanangudzo yegirazi faibha
Fiber yegirazi rudzi rwezvinhu zvisiri zvesimbi zvisingasanganisike zvinogona kutsiva simbi uye zvine mashandiro akanaka kwazvo. Inogadzirwa nekukwevera girazi rakanyungudutswa kuita fibers kuburikidza nesimba rekunze. Ine hunhu hwesimba guru, modulus yakakwira uye kurebesa kwakaderera. Kuramba kupisa uye kudzvanywa, thermal expansion coefficient yakakura, high melting point, tembiricha yayo yekunyorovesa inogona kusvika 550~750 ℃, kugadzikana kwakanaka kwemakemikari, haisi nyore kupisa, ine hunhu hwakanaka hwakadai sekudzivirira ngura, uye yakashandiswa zvakanyanya munzvimbo dzakawanda.
2 Hunhu hwegirazi faibha
Nzvimbo yekunyunguduka kwegirazi fiber ndeye 680℃, nzvimbo yekufashaira ndeye 1000℃, uye huwandu hwayo huri 2.4 ~ 2.7g/cm3. Simba rekudhonza ndiro 6.3 kusvika 6.9 g/d muchimiro chakajairwa uye 5.4 kusvika 5.8 g/d muchimiro chekunyorova.Faibha yegirazi ine simba rekudzivirira kupisa uye inodzivirira kupisa kwepamusoro-soro ine simba rakanaka rekudzivirira kupisa, iro rakakodzera kugadzirwa kwezvinhu zvinodzivirira kupisa uye zvisingatsvi.
3 Kuumbwa kwegirazi faibha
Girazi rinoshandiswa mukugadzira machira egirazi rakasiyana negirazi rinoshandiswa mune zvimwe zvigadzirwa zvegirazi. Girazi rinoshandiswa mukugadzira machira egirazi rine zvinhu zvinotevera:
(1)Girazi remagetsi,inozivikanwawo segirazi risina alkali, ndeyegirazi reborosilicate. Pakati pezvinhu zvinoshandiswa pari zvino mukugadzira magirazi, girazi risina alkali ndiro rinonyanya kushandiswa. Girazi risina alkali rine insulation yakanaka uye hunhu hwemakanika, uye rinonyanya kushandiswa kugadzira magirazi e insulation uye magirazi ane simba rakawanda, asi girazi risina alkali harina inorganic acid corrosion, saka harina kukodzera kushandiswa munzvimbo dzine acid. Tine e-glassfiberglass roving, girazi remagetsifiberglass yakarukwa inofamba-famba，uye e-girazimati efibegrlass.
(2)Girazi reC, inozivikanwawo segirazi repakati nepakati realkali. Kana ichienzaniswa negirazi risina alkali, ine simba rekudzivirira makemikari uye ine hunhu husina kunaka hwemagetsi nemakanika. Kuwedzera diboron trichloride mugirazi repakati nepakati realkali kunogona kugadziragirazi fiber pamusoro pemachira,iyo ine hunhu hwekudzivirira ngura. Fibre dzegirazi dzisina boron-medium-alkali dzinonyanya kushandiswa mukugadzira machira ekusefa uye machira ekuputira.
(3)Faibha yegirazi yakasimba kwazvo,Sezvinoratidzwa nezita racho, fiber yegirazi ine simba guru ine hunhu hwesimba guru uye modulus yakakwira. Simba rayo rekudhonza fiber i2800MPa, inova yakakwira ne25% kupfuura fiber yegirazi isina alkali, uye modulus yayo inochinjika i86000MPa, inova yakakwira kupfuura fiber yeE-girazi. Kubuda kwefiber yegirazi ine simba guru hakuna kukwira, pamwe chete nesimba rayo guru uye modulus yakakwira, saka inowanzo shandiswa mumauto, mundege nemitambo nedzimwe nzvimbo, uye hainyanyo shandiswa mune dzimwe nzvimbo.
(4)AR girazi faibha, inozivikanwawo sefayibha yegirazi inodzivirira alkali, ifayibha isingararami. Fayibha yegirazi inodzivirira alkali ine simba rakanaka rekudzivirira alkali uye inogona kudzivirira ngura yezvinhu zvine alkali yakawanda. Ine modulus yakakwira kwazvo uye inodzivirira kukanganiswa, simba rekudhonza uye simba rekukotama. Inewo hunhu hwekusatsva, kuramba chando, kuramba tembiricha nehunyoro, kuramba kutsemuka, kusapinda mvura, kusimba kwepurasitiki uye nyore kugadzira. Zvinhu zvembabvu zvekongiri yakasimbiswa nefayibha yegirazi.
4 Kugadzirira magirazi egirazi
Maitiro ekugadziragirazi faibhaKazhinji kacho kutanga kunyungudutsa zvinhu zvakagadziriswa, wozobva waita mushonga we fiberizing. Kana zvichizogadzirwa kuita semabhora egirazi fiber kana fiberglass rods, mushonga we fiberizing haugone kuitwa zvakananga. Kune maitiro matatu e fibrillation egirazi fibers:
Nzira yekudhirowa: nzira huru ndiyo nzira yekudhirowa nefilament nozzle, ichiteverwa nenzira yekudhirowa netsvimbo yegirazi uye nzira yekudhirowa nemelt drop;
Nzira yeCentrifugal: kupinza madhiramu, kupinza madhisiki edanho uye kupinza madhisiki eporcelain akatwasuka;
Nzira yekufuridza: nzira yekufuridza uye nzira yekufuridza nozzle.
Maitiro akati wandei ari pamusoro apa anogona kushandiswa pamwe chete, akadai sekudhonza nekuburitsa nezvimwewo. Kugadzira mushure mekugadzira kunoitika mushure mekugadzira fiber. Kugadzira mushure mekugadzira fiber yegirazi remachira kwakakamurwa kuita matanho maviri makuru anotevera:
(1) Munguva yekugadzira magirazi, shinda dzegirazi dzinobatanidzwa dzisati dzapinda dzinofanira kuva nehukuru hwakafanana, uye shinda pfupi dzinofanira kupfapfaidzwa nemafuta asati aunganidzwa uye kuputirwa nedhiramu nemaburi.
(2) Kuenderera mberi nekugadzirisa, zvichienderana nemamiriro ezvinhu egirazi pfupi uye pfupigirazi fiber roving pane matanho anotevera:
①Matanho mapfupi ekugadzirisa fiber yegirazi:
②Kugadzira matanho ekugadzira girazi remachira:
