Koj puas to taub qhov thermal zog ntawm fiberglass?

Kev ua tau zoo ntawmfiberglassyog tsim los ntawm nws cov tshuaj muaj pes tsawg leeg, txheej txheem ntau lawm, txheej txheem kev kho cua sov, thiab cov neeg ua hauj lwm impregnation. Ntawm ntau yam khoom tseem ceeb, nws qhov kev ua tau zoo thermal ua rau nws sawv hauv qhov chaw xws li siab - rwb thaiv tsev kub thiab kev nyab xeeb hluav taws, dhau los ua cov khoom siv tsis tseem ceeb.

 

Core Thermal Performance Yam ntxwv:

 

1. Zoo heev thermal rwb thaiv tsev (Low Thermal Conductivity)

 

Cov iav fiber ntau muaj thermal conductivity tsawg heev. Ntawm chav tsev kub (kwv yees li 25 degree), nws cov thermal conductivity yog kwv yees li 0.027 W / (m·K).

Tus nqi no qis dua li cov khoom siv hlau feem ntau (piv txwv li, steel kwv yees li 50 W / (m·K), aluminium kwv yees li 237 W / (m·K)), thiab kuj tseem qis dua ntau cov khoom siv hauv tsev thiab cov khoom siv (piv txwv li, qhob kwv yees li 1.7 W / (m·K), ntoo kwv yees li 0.1-0.2 W / (m·K)).

Qhov no tsis tshua muaj thermal conductivity txhais tau hais tias iav fiber ntau tuaj yeem cuam tshuam cov cua sov hloov mus, ua rau nws ua tau zoo -cov khoom siv thermal rwb thaiv tsev.

Temperature Influence: Thaum lub thermal conductivity ntawm iav fiber ntau nce me ntsis nrog nce ambient kub, nws qhov tseem ceeb uas tsis muaj thermal conductivity yog khaws cia nyob rau hauv ib tug ncaj dav kub ntau yam, ua rau nws haum rau rwb thaiv tsev nyob rau hauv nruab nrab mus rau kub kub.

 

2. Zoo heev High -Tub Kub Resistance thiab Non{2}}combustibility

 

Muab piv rau cov organic fibers (xws li paj rwb, ntaub plaub, polyester, nylon, aramid, thiab lwm yam), iav fiber ntau ua rau muaj kev kub ntxhov heev.

 

Nws softening kub yog siab li 550℃- 750℃. Qhov no txhais tau hais tias hauv qab no qhov kub thiab txias ntau yam, iav fiber ntau tswj lub zog txaus thiab morphological stability yam tsis muaj softening lossis deforming.

 

Qhov txiaj ntsig tseem ceeb: Tsis yog -combustible. Cov iav fiber ntau yog cov khoom siv tsis muaj zog silicate uas tsis kub hnyiab ntawm qhov kub thiab tsis tso pa phem. Cov yam ntxwv no ua rau nws zoo tagnrho rau cov ntawv thov kev nyab xeeb hluav taws (xws li rwb thaiv tsev tiv thaiv hluav taws hauv cov tsev, cov pam hluav taws kub, cov ntaub thaiv hluav taws, thiab siab -kub yeeb nkab cladding).

 

3. Thermal Shrinkage thiab nws qhov cuam tshuam rau cov khoom sib xyaw

 

Txawm hais tias cov khoom siv ntawm cov iav fiber ntau nws tus kheej tsis hloov pauv thaum rhuab ntawm qhov kub thiab txias qis dua nws qhov muag muag, thermal shrinkage tshwm sim.

 

Composite Interface Risks: Qhov kev coj tus cwj pwm thermal shrinkage no yog qhov tseem ceeb rau cov resin-raws li cov khoom sib xyaw (fiberglass reinforced plastics) reinforced fiberglass. Yog tias qhov sib txuas ntawm cov iav fiber ntau thiab cov resin matrix tsis zoo (piv txwv li, kev xaiv tus neeg saib xyuas tsis tsim nyog lossis cov txheej txheem tsis sib xws uas ua rau tsis zoo sib txuas), thaum lub sij hawm rov ua cua sov thiab cua txias (kev sib tw thermal):

 

Cov fiber ntau thiab resin deform txawv vim lawv txawv coefficients ntawm thermal expansion/contraction.

 

Lub interface tsis zoo tsis tuaj yeem hloov kev ntxhov siab lossis kev sib koom ua ke deformation.

 

Qhov no tuaj yeem ua rau qhov sib txawv ntawm kev sib cais (kev sib cais) ntawm cov fiber ntau thiab cov resin matrix.

 

Qhov tshwm sim: Interfacial debonding ua rau tsis muaj zog rau kev ncaj ncees ntawm cov khoom sib xyaw, dhau los ua cov ntsiab lus ntawm kev ntxhov siab thiab tawg qhov chaw pib, ua rau muaj kev poob qis hauv cov khoom siv zog (tshwj xeeb tshaj yog interlaminar shear zog thiab qaug zog), cuam tshuam rau nws lub sij hawm ntev - kev cia siab thiab durability.

 

Daim Ntawv Thov: Kev daws teeb meem rau siab -Tsub thiab Thermal rwb thaiv tsev xav tau

 

Raws li cov lus hais saum toj no cov khoom siv thermal, iav fiber ntau tau siv dav hauv:

 

Lub Tsev Thermal rwb thaiv tsev: iav ntaub plaub, rwb thaiv tsev xav tau / boards, siv rau phab ntsa, ru tsev, thiab cov yeeb nkab rwb thaiv tsev, txuag hluav taws xob thiab txo kev noj.

Industrial High-Tsub Rwb thaiv tsev: Rwb thaiv tsev txheej rau siab-kub kilns, pipelines, thiab khoom siv; thermal rwb thaiv tsev system; txuag hluav taws xob.

 

Kev Nyab Xeeb Hluav Taws Xob: Cov khoom siv hluav taws kub tsis muaj qhov rooj, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov pam hluav taws kub, cov txheej rwb thaiv tsev rau cov hluav taws kub, thiab cov hluav taws kub hnyiab.

Aerospace thiab Kev Thauj Mus Los: Cov rwb thaiv tsev thermal, suab rwb thaiv tsev, thiab cov khoom siv hluav taws xob rau lub dav hlau, nkoj, thiab siab - tsheb ciav hlau ceev.

Cov Khoom Siv Hauv Tsev: Cov khoom siv rwb thaiv tsev thermal rau siab - cov khoom siv kub xws li qhov cub, grills, thiab tshuab ziab khaub ncaws.

 

Cov ntsiab lus: Cov iav fiber ntau, nrog rau nws cov thermal conductivity tsawg heev (zoo rwb thaiv tsev), ultra- kub softening, thiab tsis yog -combustibility (zoo heev - kub tsis kam thiab hluav taws kev nyab xeeb), tau tsim nws cov tub ntxhais txoj hauj lwm nyob rau hauv siab - kub rwb thaiv tsev thiab fireproofing. Txawm li cas los xij, nws cov yam ntxwv ntawm lub hauv paus cua sov shrinkage kuj tseem ceeb rau peb tias kev ua kom muaj kev sib raug zoo ntawm cov fibers thiab cov resin yog qhov tseem ceeb hauv kev siv cov khoom siv sib xyaw (tshwj xeeb yog cov uas raug thermal cycling). Txhim kho qhov kev sib txuas los ntawm kev ua kom zoo tshaj plaws impregnating tus neeg sawv cev formulations (tshwj xeeb tshaj yog coupling agents) thiab cov txheej txheem tswj yog qhov tseem ceeb rau kev siv tag nrho cov nyhuv ntawm iav fiber ntau thiab ua kom lub sij hawm ntev - kev ua tau zoo ntawm cov khoom sib xyaw ua ke nyob rau hauv thermal tej yam kev mob.
