Koj paub ntau npaum li cas txog cov khoom ntawm fiberglass daim ntaub?

1. Lub cev thiab cov cuab yeej cuab tam

1. Siab zog
Fiberglass ntaubmuaj lub zog tensile siab heev, tshaj cov hlau hlau ntawm tib tus ntoo khaub lig-sectional cheeb tsam. Qhov no yog nws cov yam ntxwv tseem ceeb raws li cov khoom siv txhawb zog, txhim kho lub zog ntawm cov khoom siv sib xyaw.

2. Lub teeb yuag
Qhov ntom ntawm iav fiber ntau yog kwv yees li 2.5-2.7 g / cm³, qis dua li cov hlau. Qhov no tso cai rau cov khoom sib xyaw kom muaj lub zog siab thaum lub teeb yuag, nthuav tawm lub zog tshwj xeeb (lub zog / ntom).

3. Zoo Dimensional Stability
Nrog rau qhov qis coefficient ntawm thermal expansion, nws cov duab thiab qhov loj me hloov me me txawm tias nyob rau hauv qhov kub hloov pauv loj, tsis zoo li cov hlau uas muaj cov thermal expansion thiab contraction tseem ceeb.

4. Tsawg Creep
Nyob rau hauv tas li ntawd load, nws tsis yooj yim undergo qeeb, mus tas li deformation (creep), tswj nws cov duab thiab kev ua tau zoo nyob rau lub sij hawm ntev.

5. Tsis yog-combustible
Cov iav fiber ntau yog cov khoom siv tsis zoo, tiv taus qhov kub thiab txias, tsis yog -combustible, thiab ua tau raws li Class A cov qauv hluav taws kub, pom cov hluav taws zoo heev- cov khoom retardant.

 

2. Cov khoom siv tshuaj

1. Zoo heev Corrosion Resistance: Exhibits zoo heev corrosion kuj rau feem ntau cov tshuaj, tsis pwm, thiab yog resistant rau acids thiab alkalis (tshwj tsis yog hydrofluoric acid thiab kub concentrated phosphoric acid). Cov yam ntxwv no ua rau nws zoo tagnrho rau kev tsim cov tso tsheb hlau luam, kav dej, chimneys, thiab lwm yam, hauv kev lag luam tshuaj.

2. Pwm thiab Kab Tiv Thaiv: Ua los ntawm iav, nws tsis muab cov khoom noj rau pwm, kab mob, los yog kab, yog li nws yuav tsis pwm, rot, los yog kab mob.

 

3. Cov khoom siv hluav taws xob thiab cua sov

1. Cov rwb thaiv tsev zoo heev: Muaj cov khoom siv hluav taws xob zoo heev, ua rau nws yog cov khoom siv zoo tshaj plaws rau kev tsim ntau yam hluav taws xob insulating Cheebtsam (xws li Circuit Court board substrate - FR4).

2. Zoo thermal rwb thaiv tsev: muaj cov thermal conductivity tsawg, ua rau nws yog ib qho zoo heev thermal rwb thaiv tsev cov ntaub ntawv, feem ntau siv nyob rau hauv lub tsev rwb thaiv tsev, industrial cov khoom rwb thaiv tsev, thiab lwm yam.

3. Kub Kub Resistance: Nyob ntawm cov iav muaj pes tsawg leeg, nws qhov muag muag feem ntau yog siab tshaj 600 degree. Qee cov qauv tshwj xeeb (xws li siab -silica fiber ntaub) tuaj yeem ua haujlwm tsis tu ncua ntawm qhov kub siab tshaj 1000℃.

 

4. Kev ua haujlwm zoo

1. High Designability: Mechanical zog thiab resin impregnation tuaj yeem raug tsim los ntawm kev xaiv cov xov paj sib txawv, weaves (dawb weave, twill weave, satin weave, thiab lwm yam) thiab thicknesses kom tau raws li qhov xav tau ntawm ntau yam khoom.

2. Zoo Lamination Properties: Cov kev ntxhib los mos mos tso cai rau cov lamination yooj yim raws li cov duab puab, tsim rau cov khoom tsim nrog ntau yam duab, xws li nkoj hulls thiab cov khoom siv tsheb.

 

5. Qhov tsis zoo (Cons)

1. Brittleness thiab Poor Abrasion Resistance: Cov iav fiber ntau nws tus kheej muaj qhov tsis zoo bending yooj thiab nws nquag tawg tom qab rov folding. Cov txheej txheej saum npoo feem ntau yuav tsum tau tiv thaiv cov fibers thiab txhim kho daim ntawv cog lus nrog cov resin.

2. Tsis zoo Abrasion Resistance: Surface fibers tau yooj yim puas los ntawm kev sib txhuam.

3. Cov tawv nqaij khaus: Kev sib cuag nrog cov iav fiber ntau tuaj yeem ua rau khaus thiab ua xua; Cov cuab yeej tiv thaiv (cov hnab looj tes, qhov ncauj qhov ntswg, ntev- khaub ncaws hnav) yuav tsum tau ua thaum tuav.

 

Cov cheeb tsam tseem ceeb ntawm daim ntawv thov

 

1. Hluav taws xob thiab hluav taws xob: Substrate rau Printed Circuit Boards (PCBs).

2. Aerospace: Siab-kawg cov khoom siv rau cov khoom siv dav hlau, cov qauv satellite, thiab lwm yam.

3. Kev thauj mus los: Lub cev tsheb, cov tsheb thauj khoom, lub nkoj nkoj, nkoj nkoj, cov roj teeb pob casings rau cov tsheb tshiab, thiab lwm yam.

4. Cov Khoom Siv Hauv Tsev: Cov pob zeb ua kom muaj zog (GRC), cov ntaub ntawv tsis muaj dej, cov ntaub ntawv rwb thaiv tsev, cov ntawv vov tsev, thiab lwm yam.

5. Kev Ua Si thiab Leisure: nuv ntses pas nrig, ntaus golf, hneev thiab xub, caij ski, kaus mom hlau, thiab lwm yam.

6. Muaj Kev Tiv Thaiv Corrosion: Corrosion-cov ntaub ntawv tiv thaiv rau cov kav dej, lub tank cia, chimneys, thiab cov tshuaj txhuam hniav.

7. Cua fais fab tiam: Cov khoom siv tseem ceeb rau cov cua turbine hniav.
