Kev ua tau zoo thiab qhov tshwm sim zoo xav tau ntawm Fiberglass

Qhov kawg khoom ntawmfiberglassyog qhov tshwm sim los ntawm kev sib xyaw ua ke ntawm nws qhov sib xyaw ua ke, cov txheej txheem tsim khoom, kev kho cua sov, thiab cov txheej txheem txheej txheej sizing. Txhawm rau ua kom tau raws li daim ntawv thov kev thov hauv ntau qhov chaw xws li cov khoom siv sib xyaw ua ke, hluav taws xob rwb thaiv tsev, thiab kev pom kev lag luam, fiberglass yuav tsum muaj cov kev ua tau zoo thiab cov qauv zoo.

Core Performance Influencing Factors

Lub hauv paus ntsiab lus: Cov tshuaj muaj pes tsawg leeg ntawm fiberglass (piv txwv li, alkali-dawb E-fiberglass, nruab nrab-alkali C-fiberglass, siab-lub zog S-fiberglass) yog qhov tseem ceeb rau kev txiav txim siab nws cov ntsiab lus tseem ceeb xws li cov khoom siv hluav taws xob, hluav taws xob, hluav taws xob, hluav taws xob thiab hluav taws xob. tsis kam.

Txheej Txheem Shaping: Cov txheej txheem tsim khoom (piv txwv li, tank furnace drawing lossis crucible drawing) ncaj qha cuam tshuam rau fiber ntau txoj kab uas hla uniformity, tus naj npawb ntawm qhov tsis xws luag, thiab microstructure.

Kev Tiv Thaiv Thaum Kub Kub: Cov txheej txheem kho cua sov (xws li, cov fiber ntau ziab, cov khoom siv hluav taws xob tom ntej) tuaj yeem tshem tawm cov dej noo thiab cov kev ntxhov siab, thiab tuaj yeem hloov cov kev ua ntawm fiber ntau.

Lub luag hauj lwm ntawm sizing tus neeg sawv cev: tus neeg sawv cev sizing tsis tsuas yog muab kev tiv thaiv (lubrication, bundling, antistatic), tab sis tseem ceeb tshaj, nws cov Cheebtsam (tshwj xeeb tshaj yog coupling agents) txiav txim lub interfacial bonding kev ua tau zoo ntawm fiber thiab resin matrix, yog li cuam tshuam rau qhov kawg mechanical zog, durability, thiab ib puag ncig tsis kam ntawm cov khoom sib xyaw.

Qhov tseem ceeb ntawm kev ua tau zoo thiab qhov tshwm sim zoo yuav tsum tau ua

1. Cov yam ntxwv tshwm sim:

Surface Morphology: Tsis zoo li cov organic fibers nrog sib sib zog nqus wrinkles (xws li paj rwb, linen, thiab polyester), fiberglass monofilaments feem ntau pom ib tug du, cylindrical nto. Qhov saum npoo du no yog tus yam ntxwv ntawm kev ua haujlwm siab - nrawm nrawm.

Hla -sectional Shape: Hauv lub tshuab ntsuas qhov ntsuas, tus ntoo khaub lig- seem ntawm fiberglass feem ntau tshwm ua lub voj voog tiav. Txawm li cas los xij, nws tsim nyog sau cia tias kuj tseem muaj fiberglass ntau yam nrog cov ntoo khaub lig tsis sib xws - ntu; cov irregularly zoo li tus fibers yog tej zaum tsim los txhim kho cov neeg kho tshuab kev sib raug zoo nrog cov resin.

Zuag qhia tag nrho cov tsos: Cov nqaij nyoos los yog cov xov paj yuav tsum muaj xim zoo ib yam thiab tsis muaj qhov pom tseeb, roj, fuzz, lossis tawg filaments.

2. Density (Specific Gravity): fiberglass has a significantly higher density than common organic fibers (such as polyester fiber approximately 1.38 g/cm³, and polypropylene fiber approximately 0.91 g/cm³).

Txawm li cas los xij, piv rau cov hlau fibers (xws li steel fiber ntau kwv yees li 7.8 g / cm³), fiberglass yog qhov sib dua.

Nws qhov ntom ntom feem ntau yog li ntawm 2.4 txog 2.7 g / cm³, zoo ib yam li qhov ntom ntawm txhuas (kwv yees li 2.7 g / cm³). Qhov nruab nrab ntom ntom no ua rau nws muaj txiaj ntsig zoo hauv cov khoom siv sib xyaw uas xav tau lub teeb yuag thiab lub zog siab (xws li aerospace, tsheb, thiab kev siv dej hiav txwv).

Yog li ntawd, qhov yuav tsum tau ua kom pom tseeb ntawm cov iav fiberglass (lub tog raj kheej du, feem ntau nrog cov hlaws zoo kawg nkaus - ntu, huv si thiab zoo ib yam) thiab nws qhov ntom ntom (2.4-2.7 g / cm³) yog qhov tseem ceeb rau nws siv los ua cov khoom lag luam muaj txiaj ntsig zoo, cuam tshuam ncaj qha rau nws cov kev ua tau zoo, kev sib xyaw ua ke, thiab kev ua kom zoo dua qub. Cov ntsuas no, nrog rau kev sib xyaw ua ke, kev ua haujlwm, kev kho cua sov, thiab cov neeg ua haujlwm impregnating, ua kom tiav cov txheej txheem rau kev ntsuas qhov zoo ntawm fiberglass.
