txoj moo

Cov ntaub ntawv fiberglass yog kev ua tau zoo ntawm inorganic cov ntaub ntawv tsis yog xim hlau, kub ua rau muaj zog, tab sis qhov tsis zoo yog rab phom, coj tsis zoo yog qhov tsis zoo. Nws yog lub khob iav lossis pov tseg iav ua cov ntaub ntawv rawting ntawm ob peb lub microns rau ntau dua 20 / 20-1 / 5, txhua pob ntawm cov neeg muaj ntau txhiab tus neeg nyob ntawm cov tawv nqaij nyoos.Iav yasFeem ntau yog siv los ua cov khoom siv uas txhawb ntxiv hauv cov khoom siv sib xyaw, cov hluav taws xob cov ntaub ntawv hluav taws xob thiab cov rooj tsav tsheb hluav taws xob thiab lwm yam ntawm kev lag luam hauv tebchaws.
1, cov yam ntxwv ntawm lub cev ntawm fiberglass
Melting point 680 ℃
Kub taw tes 1000 ℃
Ntom ntom 2.4-2.7g / cm³

2, Tshuaj lom neeg muaj pes tsawg leeg
Lub ntsiab lus tseem ceeb yog silica, alumina, borium oxide, sodium alkide tshuab (sodium oxide (sodium oxide) (sodium oxide) Boron-Free Soda-txiv qaub Silicate iav) thiab High Alkali fiberglass (sodium oxide 13% lossis ntau dua, yog dej qab zib-txiv qaub siic). ).

3, cov ntaub ntawv nyoos thiab lawv cov ntawv thov
Fiberglass dua organic fibers, kub, tsis-sib xyaw ua ke, tiv thaiv corrosion, thermal thiab acoustic rwb thaiv tsev, lub zog hluav taws xob siab, zoo hluav taws xob. Tab sis nkig, tsis zoo ua tsis kam. Siv nyob rau hauv kev tsim cov khoom siv txhawb los yog txhawb cov roj hmab, raws li kev txhawb nqa cov yam ntxwv hauv qab no, ua ntej nws cov yam ntxwv tau teev nyob hauv qab no:
(1) lub zog siab tensile lub zog, me elongation (3%).
(2) cov coefficient ntawm elasticity, zoo rigidity.
(3) elongation nyob rau hauv cov kev txwv ntawm elasticity thiab siab tensile lub zog, yog li nqus cov kev cuam tshuam lub zog.
(4) inorganic fiber ntau, tsis muaj kev sib txuas, cov tshuaj tsis zoo.
(5) Kev nqus dej me me.
(6) Cov nplai zoo ruaj khov thiab kub ua kom tsis kam.
(7) Cov txheej txheem zoo, tuaj yeem ua rau hauv strands, bundles, felts, felts thiab lwm cov khoom sib txawv ntawm cov khoom lag luam.
(8) Cov khoom lag luam pob tshab tuaj yeem hloov lub teeb.
(9) Kev loj hlob ntawm cov neeg saib xyuas kev kho deg nrog cov nplaum zoo rau cov khoom xa tuaj.
(10) pheej yig.
(11) Nws tsis yooj yim mus hlawv thiab tuaj yeem ua tau fused rau hauv khob hlaws dai ntawm qhov kub.
Fiberglass raws li daim foos thiab ntev, tuaj yeem muab faib ua cov fiber ntau, tsau-ntev fiber ntau thiab cov ntaub plaub ntses; Raws li cov iav muaj pes tsawg leeg, tuaj yeem faib ua cov tshuaj txhuam tsis zoo, muaj zog, muaj zog, muaj txiaj ntsig zoo ntawm kev tiv thaiv (anti-alkali) fiberglass thiab li ntawd.

4, lub ntsiab raw cov ntaub ntawv rau kev tsim coviav yas
Tam sim no, lub ntsiab raw cov ntaub ntawv rau cov tshuab fiberglass yog Quartz xuab zeb, dolomite, boroms acid, boronese, fluorite, fluorite thiab li ntawd.

5, Txuj Ci Ntau Lawm
Kwv yees muab faib ua ob pawg: ib qho yog ua los ntawm cov iav molten ncaj qha rau hauv cov fibers;
Ib chav kawm ntawm molten iav yog thawj zaug ua los ntawm iav pob lossis pas nrig nrog txoj hauv kev ntawm 20 hli, thiab tom qab ntawd rov qab ua kom sov ua kom zoo nkauj nrog lub cheeb ntawm 3 ~ 80μm.
Los ntawm cov platinum alloy phaj rau cov kev kos duab kev kos duab mus rau rub tawm qhov ntev, lub npe hu ua cov iav txuas ntxiv, feem ntau yog paub ntev li ntev fiber ntau.
Los ntawm cov menyuam lossis cov cua ua los ntawm cov khoom siv tsis sib xws, hu ua tsau-ntev fiberglass, feem ntau yog hu ua luv luv fibers.

6, kev faib tawm fiberglass
Fiberglass raws li cov muaj pes tsawg leeg, xwm thiab siv, muab faib ua ntau qib.
Raws li cov txheej txheem theem kev cai, E-Chav Iav Fiber yog qhov siv ntau tshaj plaws, siv tshuab hluav taws xob rwb thaiv tsev;
S-chav rau cov Fibers tshwj xeeb.
Kev tsim cov fiberglass nrog iav yog txawv ntawm lwm cov khoom lag luam.
Thoob ntiaj teb ua lag luam fiberglass muaj raws li hauv qab no:

(1) e-iav
Kuj tseem hu ua cov iav dawb alkali, yog lub borosilicate iav. Tam sim no yog ib qho ntawm feem ntau cov iav fiber ntau iav muaj pes tsawg leeg, nws qhov tsis zoo siv rau cov roj ntsha li cas rau cov roj ntsha li cas rau cov kua roj ntsha, yog li nws tsis haum rau kev siv hauv cov acidic ib puag ncig.

(2) c-iav
Kuj tseem hu ua nruab nrab alkali iav, uas yog tus cwj pwm los ntawm cov tshuaj lom neeg muaj txiaj ntsig zoo dua li alkali iav iav Nyob rau hauv txawv teb chaws teb chaws, nruab nrab alkali fiberglass tsuas yog siv rau kev tsim cov khoom siv roj fiber ntau (60%), kuj siv cov khoom siv tshuaj ntsuab Ntawm nws tus nqi yog qis dua tus nqi ntawm cov iav khob uas tsis yog alkaline fiber ntau thiab muaj lub zog sib tw.

(3) Lub zog loj
Tsiag ntawv los ntawm lub zog siab thiab cov modulus siab, nws muaj ib qho kev sib zog ntawm lub zog ntawm txoj kev ywj pheej ntawm kev sib tw Daim FRP cov khoom tsim tawm nrog lawv feem ntau siv nyob rau hauv cov tub rog, qhov chaw, cov khoom lag luam baperproof thiab cov khoom siv kis las. Txawm li cas los xij, vim yog tus nqi kim, tam sim no hauv cov haiv neeg tsis tuaj yeem txhawb nqa, lub ntiaj teb kev tsim yog tsuas yog ob peb txhiab tons lossis li ntawd.

(4)Ar fiberglass
Kuj tseem hu ua alkali-resistant fiberglass, alkali-resistant fiberglass tau txhawb nqa (MAAs) pob zeb ua (xis nyob hloov chaw rau cov hlau thiab asbestos zoo tshaj plaws. Alkali-resistant fiberglass yog tus cwj pwm zoo, tuaj yeem tiv thaiv lub zog, nthuav dav dav, yooj yim rau cov qauv muaj zog, yooj yim rau daim ntawv, thiab lwm yam, Alkali-resistant fiberglass yog hom tshiab ntawm kev txhawb nqa cov khoom uas tau siv dav hauv kev ua tau zoo (xis mas) pob zeb. Cov khoom siv ntsuab ntxiv.

(5) Ib khob
Kuj tseem muaj lub npe zoo li iav siab, yog ib qho sodium silicate silicate iav, vim tsis muaj dej tsis kam, tsis tshua siv nyob rau hauv kev tsim cov fiberglass.

(6) e-cr iav
E-Cr G iav yog ib hom kev txhim kho cov iav zoo nkauj hauv Boron-dawb, uas yog siv rau kev tsim cov fiberglass nrog cov kua qaub zoo thiab dej tsis kam. Nws cov dej tsis kam yog 7-8 lub sij hawm zoo tshaj li ntawm alkali-dawb fiberglass, thiab nws cov kua qaub ua kuj tseem zoo tshaj li qhov tshiab tsim rau cov kav dej hauv av thiab tso tsheb hlau luam.

(7) d iav
Kuj tseem hu ua lub iav qis, nws yog siv los tsim cov fibergall fiberglass qis nrog lub zog dielectric zoo.
Ntxiv nrog rau cov lus qhia fiberglass saum toj no, muaj tam sim no tshiabAlkali-dawb fiberglass, nws yog kiag li boron dawb xwb, yog li txo cov pa phem ib puag ncig, tab sis nws cov hluav taws xob rwb thaiv tsev zog thiab cov tshuab siv tau zoo ib yam li cov tsoos e iav.
Kuj tseem muaj ob lub iav muaj pes tsawg leeg ntawm fiberglass, tau raug siv hauv kev tsim cov iav plaub, hauv cov khoom siv fiberglass txhawb ntxiv kuj muaj peev xwm. Ntxiv rau kev ntxiv fluorine-dawb iav fibers, yog tsim rau ib puag ncig cov cai thiab txhim kho alkali-dawb fiberglass.

7. Daim Ntawv Qhia Txog Cov Mickali Hiberglass
Qhov kev xeem yog txoj kev yooj yim los muab cov fiber ntau hauv dej npau npau thiab ua noj ua haus 6-7H, yog tias nws yog cov hmoov av

8. Muaj ob hom ntawm cov txheej txheem ntau lawm
a) ob zaug moulding - txheej txheem crucible;
b) ib zaug molding - Pas dej Kiln ntawm txoj kev kos.
Crucible kos duab txheej txheem, thawj lub siab-kub yaj ntawm iav cov khoom nyoos ua cov iav cov khoom, thiab tom qab ntawd cov duab ceev ua los ntawm cov fiberglass fiberglass. Cov txheej txheem no muaj kev siv hluav taws xob siab, Moulding txheej txheem tsis ruaj khov, muaj lwm yam kev tsis zoo, tau tshem tawm cov iav loj cov tshuab hluav taws xob.

9. RaugIav yasKev ua
Pas dej ua ke ntawm cov ntaub ntawv ntawm chlorite thiab lwm cov ntaub ntawv raw rau hauv cov kab mob iav los ntawm cov phaj txhaws hauv cov fiberglass ntsiab lus. Lub Kiln tuaj yeem txuas nrog ntau pua ntawm cov vaj huam sib luag los ntawm ntau txoj kev hauv kev sib txuas. Cov txheej txheem no yooj yim, muaj zog-txuag, ruaj khov moulding, thiab muaj cov txheej txheem ntawm kev tsim cov fiberglass ua ke rau ntau dua 90% ntawm kev tsim khoom thoob ntiaj teb.
