Fiberglass - Tus Hero Unsung Qab Cov Hlau Skeleton Ntawm Engineering Plastics

Feem ntau siv fiberglass hauv kev hloov kho plastics kev lag luam tuaj yeem faib los ntawm kev sib xyaw thiab daim ntawv:

 

Classification los ntawm Chemical Composition:

* **Alkali- DawbFiberglass(E Fiberglass): ** Alkali cov ntsiab lus<1%, balanced insulation, strength, and water resistance; highest production volume; used in wind turbine blades, PCBs, and plastic modification.

* ** Nruab nrab-Alkali iav Fiber (C iav Fiber):** Alkali ntsiab lus 6%-12%, zoo acid kuj, tsis muaj zog rwb thaiv tsev, tsis muaj nqi; siv rau tshuaj tiv thaiv corrosion thiab asphalt waterproofing.

 

Kev faib tawm los ntawm Daim Ntawv Thov:

* ** Nruam Untwisted Long Glass Fiber: ** Cov iav fibers tau kos rau hauv cov pob khoom thiab lub qhov txhab rau hauv cov yob siv rau hauv kev ua textile thiab kev txhim kho cov qauv.

* ** Txiav-Tawm iav Fiber:** iav fiber ntau yob uas txiav luv luv tom qab kho deg; ntau yam loj rau kev hloov kho yas thiab kev txhawb zog.

* ** Flat iav Fiber:** Muaj ntau yam tshwj xeeb; iav fibers nrog tus ntoo khaub lig elliptical -section tswj thaum lub sij hawm kos duab; muaj nyob rau hauv ntev thiab txiav -tawm daim ntawv. Nws nthuav tawm cov kev ua haujlwm tshwj xeeb hauv kev siv.

 

Yuav Ua Li Cas Fiberglass Tsim "Steel thiab Iron Bones" ntawm Plastics

 

Qhov laj thawj tseem ceeb vim li cas fiberglass yog tus khub zoo tshaj plaws rau cov yas yas hauv nws lub peev xwm los them rau qhov kev ua haujlwm tsis zoo ntawm cov yas yas los ntawm kev sib koom ua ke "fiber-" cov nyhuv thiab cohesive quab yuam hloov.

 

Mechanical Strengthening: Zoo li ntxiv "steel tuav" rau cov yas, lub zog tensile tuaj yeem nce los ntawm 20% mus rau 100%, thiab cuam tshuam rau qhov hnyav tuaj yeem ncav cuag qib hlau;

Deformation Resistance: Nws inhibits resin shrinkage, ua rau cov khoom tsis tshua muaj kev cuam tshuam rau hauv qhov kub thiab txias, nrog cov nqi shrinkage tswj kom tsawg kawg yog 0.15%;

Kev Ntsuas Tus Nqi: Piv rau cov khoom siv hluav taws xob ntshiab, fiber ntau- cov khoom siv ntxiv tuaj yeem ua tiav cov kev ua haujlwm siab ntawm tus nqi qis. Piv txwv li, siv fiberglass PA ntev los hloov cov hlau hauv cov khoom siv tsheb txo qhov hnyav los ntawm 50% thaum txo cov nqi los ntawm 30%.

 

Dab tsi yog qhov txawv ntawm ntau hom Fiberglass hauv Plastics?

 

Txawm li cas los xij, ntau hom fiberglass ua rau muaj qhov sib txawv loj heev rau cov yas. Xaiv hom zoo tuaj yeem ua ob npaug ntawm cov khoom ua haujlwm; xaiv qhov tsis ncaj ncees lawm yuav ua rau muaj teeb meem xws li raug fiberglass thiab yooj yim tawg. Feem ntau siv iav fibers feem ntau muaj peb hom: iav fibers ntev, iav fibers luv, thiab iav fibers. Lawv txawv heev nyob rau hauv morphology, kev ua tau zoo, kev ua, thiab daim ntawv thov scenarios.

 

Ntev iav fibers ua zoo li "khoom steel tuav," ua ib qho kev sib txuas txuas ntxiv hauv cov resin, zoo hloov kev ntxhov siab. Qhov no yog vim li cas lawv lub zog cuam tshuam yog 50% mus rau 100% siab dua li ntawm cov iav luv luv.

Cov iav luv luv ua zoo li "pob zeb crushed," uniformly dispersed tab sis nrog ntev ntev, haum rau daim ntaub ntawv uas yuav tsum tau siab isotropy.

Pav ca iav fibers ua zoo li "nyias steel ntawv," nrog ib tug tuab ntawm 3-10 μm thiab ib tug dav ntawm 50-200 μm, tso cai rau ib tug 3-5 lub sij hawm loj kev sib cuag cheeb tsam nrog cov resin piv rau puag ncig iav fibers, uas ua rau ib tug ho txhim khu kev qha nto.

Cov yam ntxwv tshwm sim

① Flat iav Fiber puv nrog PC

Vim nws tiaj tus, ribbon-zoo li cov qauv, thaj chaw sib cuag nrog PC resin yog 3-5 npaug loj dua li cov iav fibers ntawm tib qhov hnyav, uas ua rau muaj kev hloov pauv ntawm fiber ntau-resin interface. Ua ke nrog qhov tsawg ntawm qhov roughness ua tiav los ntawm kev kos duab tshwj xeeb, qhov no ua rau lub ntsej muag siab dua ( ntsuas ntawm 60℃kaum sab xis).

 

② Short Iav Fiber Filled PC: Qhov luv thiab sib cais fibers ua rau lub teeb tawg yooj yim dua. Txawm li cas los xij, qhov sib cuam tshuam ntawm puag ncig tus ntoo khaub lig- seem fiber ntau thiab cov resin tseem muaj qhov cuam tshuam me ntsis, ua rau gloss theem qis dua li cov iav fiber ntau, feem ntau ntawm 70 thiab 80. Cov nyhuv fiber ntau qhov chaw xav tau ntau dua ntawm cov txheej txheem molding.

 

③ Ntev iav Fiber Filled PC: Ntev fibers (6-}12mm) zoo li sib sau ua ke thaum lub sij hawm ua, thiab cov fiber-resin interface muaj me me me me vim "skeleton effect," ua rau diffuse reflection ntawm lub teeb nyob rau hauv cov cheeb tsam no. Cov qib gloss tsuas yog 50-60, ua rau lub ntsej muag me ntsis, ua rau nws tsim nyog rau cov khoom siv xws li engineering machinery vaj tse.

Mechanical Properties:

Qhov ntev ntawm cov iav fiber ntau hauv cov yas, cov ntsiab lus sib txuas ntau dua ntawm cov iav fiber ntau thiab cov resin, ua rau lub zog zoo dua. Cov iav fiber ntau ntev tuaj yeem suav hais tias yog qhov tsis sib haum xeeb "lub zog sib tw". Cov ntaub ntawv qhia tau hais tias, ntawm tib cov ntsiab lus, lub zog tensile ntawm ntev iav fiber reinforced PA yog 20% ​​-30% siab dua li cov iav fiber ntau luv, thiab qhov cuam tshuam rau lub zog yog 50% -60% siab dua, ua rau nws tshwj xeeb tshaj yog haum rau cov kev ntxhov siab mus sij hawm ntev xws li automotive bumpers thiab motor fan blades.

 

Luv iav fibers ua tau zoo hauv "sib npaug." Thaum lub zog me ntsis tsis muaj zog, lawv pom cov isotropy zoo, ua rau muaj qhov sib txawv me me ntawm cov lus qhia sib txawv, ua rau lawv haum rau precision qhov chaw xws li lub zog thiab cov khoom sib txuas.

 

Flat iav fibers, ntawm qhov tod tes, muab me ntsis txhim kho "sab toughness." Siv cov iav ca fibers los txhawb cov silicone copolymer PC hauv cov xov tooj ntawm tes, txhim kho kev poob qis los ntawm 40% thiab zam qhov tsis xws luag ntawm "pob iav fibers."

Dimensional Stability Performance

Ntev iav fibers '"skeleton nyhuv" zoo tuav cov resin nyob rau hauv qhov chaw, ua tiav ib tug shrinkage tus nqi qis li 0.15% nyob rau hauv cov kev taw qhia ntws. Txawm li cas los xij, qhov sib txawv ntawm qhov sib txawv ntsug yog qhov tseem ceeb, ua rau loj - thaj chaw tiaj tiaj tiaj ua rau muaj kev sib tsoo.

Cov iav luv luv shrinks ntau uniformly, ua rau lawv haum rau me me mus rau nruab nrab - qhov loj me.

Flat iav fibers, nrog rau lawv cov qauv tiaj tus, muaj kev txwv ntau dua nyob rau hauv - dav hlau shrinkage, ua rau lawv qhov kev xaiv zoo tshaj plaws rau tsheb sab hauv vaj huam sib luag.

 

Daim Ntawv Thov Tsim Nyog: Muab Txoj Cai Fiber rau hauv Qhov Chaw Zoo

 

Tsis muaj qhov zoo tshaj plaws iav fiber ntau, tsuas yog xaiv txoj cai xwb. Cia peb saib ntawm "qhov tseem ceeb sib ntaus sib tua" ntawm cov iav fiber ntau sib txawv.

 

Ntev iav Fiber: "Tus Thawj Coj" ntawm Kev Lag Luam hnyav Rau cov khoom uas xav tau ntev - lub sij hawm cuam tshuam thiab thauj khoom tsis kam, xws li tsheb chassis brackets, kev tsim tshuab vaj tse, thiab caij ski binding, iav fiber ntau yog qhov kev xaiv zoo tshaj plaws. Verton's ntev iav fiber ntau cable txhawb nqa nyob rau hauv corrosion-dawb rau kaum xyoo nyob rau hauv underground ib puag ncig, kiag li daws cov xeb teeb meem ntawm hlau txhawb.

 

Luv iav fiber ntau: "tus huab tais ntawm tus nqi-kev ua tau zoo" hauv cov khoom siv niaj hnub. Rau tus nqi- qhov tseem ceeb tseem ceeb hauv cov khoom muaj zog xws li lub tshuab ntxhua khaub ncaws, lub tshuab cua txias compressor brackets, thiab cov khoom siv hluav taws xob, cov iav fiber ntau luv luv yog qhov zoo kawg nkaus.

 

Flat iav fiber ntau: Kev sib xyaw ua kom zoo nkauj thiab kev ua tau zoo. Rau cov khoom uas yuav tsum tau muaj kev poob siab thiab kev zoo nkauj, xws li cov xov tooj ntawm tes, lub laptop A- sab, thiab cov tsheb sab hauv vaj huam sib luag, cov iav fiber ntau ua tiav daim iav- zoo li nto thaum tuav lub zog txaus txawm tias phab ntsa tuab ntawm tsuas yog 0.8 hli.
