Mitundu Yodziwika ya Glass Fiber Mats ndi Nsalu

Glass Fiber Mats

1.Chopped Strand Mat (CSM)Glass fiber roving(nthawizinanso mosalekeza) amadulidwa mu utali wa 50mm, mwachisawawa koma mofananamo amaikidwa pa lamba wa mesh conveyor. Kenako, emulsion binder imayikidwa, kapena chomangira cha ufa chimathiridwapo fumbi, ndipo zinthuzo zimatenthedwa ndikuchiritsidwa kuti apange mphasa wodulidwa. CSM imagwiritsidwa ntchito makamaka pakuyika manja, kupanga mapanelo mosalekeza, kuumba kofananira, ndi njira za SMC (Sheet Molding Compound). Zofunikira zamtundu wa CSM ndi:

• Kulemera kwa dera lofanana m'lifupi mwake.
• Kugawa yunifolomu ya zingwe zodulidwa pamphasa pamwamba popanda voids lalikulu, ndi kugawa yunifolomu binder.
• Mphamvu zolimba za mphasa zowuma.
• Wabwino resin wetting ndi malowedwe katundu.

2.Continuous Filament Mat (CFM)Magalasi opangidwa ndi magalasi omwe amapangidwa panthawi yojambula kapena osavulazidwa kuchokera m'matumba oyendayenda amayalidwa pansi pazithunzi zisanu ndi zitatu pa lamba wa mauna osasunthika ndikumangirira ndi chomangira cha ufa. Popeza ulusi mu CFM ndi mosalekeza, amapereka chilimbikitso bwino zipangizo gulu kuposa CSM. Amagwiritsidwa ntchito makamaka pakupanga pultrusion, RTM (Resin Transfer Molding), thumba loponderezedwa, ndi njira za GMT (Glass Mat Reinforced Thermoplastics).

3.Surfacing MatZogulitsa za FRP (Fiber Reinforced Plastic) nthawi zambiri zimafunikira utomoni wochuluka wa pamwamba, womwe umatheka pogwiritsa ntchito magalasi apakati a alkali (C-glass) pamwamba pa mphasa. Monga mphasa iyi imapangidwa kuchokera ku C-galasi, imapereka FRP kukana mankhwala, makamaka kukana asidi. Kuonjezera apo, chifukwa cha kuonda kwake komanso kukula kwake kwa ulusi, imatha kuyamwa utomoni wochulukirapo kuti upangire utomoni wochuluka, kuphimba kapangidwe ka zinthu zolimbitsa magalasi (monga kuluka) ndikugwira ntchito ngati kumaliza.

4.Zofunika MatZitha kugawidwa mu Chopped Fiber Needled Mat ndi Continuous Filament Needled Mat.

•  Wodulidwa Fiber Wofunika Matamapangidwa ndi kudula magalasi ulusi wozungulira mu utali wa 50mm, kuwayika iwo mwachisawawa pa gawo lapansi lomwe linayikidwa kale pa lamba wonyamulira, ndiyeno nkumamanga ndi singano zaminga. Singanozo zimakankhira ulusi wodulidwa mu gawo lapansi, ndipo mipiringidzo imabweretsanso ulusi wina, kupanga mawonekedwe atatu. Gawo lapansi lomwe limagwiritsidwa ntchito litha kukhala nsalu yoluka yagalasi kapena ulusi wina. Mtundu woterewu wa mphasa wosanjidwa umakhala ndi mawonekedwe omveka. Zomwe zimagwiritsidwa ntchito kwambiri zimaphatikizapo zida zotenthetsera zotenthetsera ndi zokutira, zida zomangira, ndi zida zosefera. Itha kugwiritsidwanso ntchito popanga FRP, koma FRP yomwe imachokera imakhala ndi mphamvu zochepa komanso kuchuluka kwa ntchito.
•  Ulusi Wosalekeza Wofunika Matamapangidwa mwachisawawa kuponya mosalekeza magalasi ulusi filaments pa mosalekeza mauna lamba ntchito ulusi kufalitsa chipangizo, kenako zisa ndi bolodi singano kupanga mphasa ndi interloven atatu azithunzi-thunzi CHIKWANGWANI dongosolo. Makasi awa amagwiritsidwa ntchito makamaka popanga magalasi opangidwa ndi magalasi opangidwa ndi thermoplastic stampable sheets.

5.Zosokedwa MatUlusi wagalasi wodulidwa kuyambira 50mm mpaka 60cm m'litali ukhoza kusokedwa pamodzi ndi makina osokera kuti apange mphasa wodulidwa wodulidwa kapena mphasa wautali. Yoyambayo imatha kulowa m'malo mwa CSM yomangika m'mapulogalamu ena, ndipo yomalizayo imatha kusintha CFM. Ubwino wawo wamba ndi kusowa kwa zomangira, kupewa kuipitsa panthawi yopanga, kuchita bwino kwa utomoni wa utomoni, komanso kutsika mtengo.

Zovala za Glass Fiber

Zotsatirazi zikuwonetsa mitundu yosiyanasiyana ya nsalu zamagalasi zopangidwa kuchokeragalasi fiber ulusi.

1.Nsalu yagalasiNsalu zamagalasi zomwe zimapangidwa ku China zimagawidwa kukhala zopanda alkali (E-galasi) ndi mitundu yapakatikati ya alkali (C-glass); kupanga zambiri zakunja kumagwiritsa ntchito nsalu yagalasi ya E-GLASS yopanda alkali. Nsalu zamagalasi zimagwiritsidwa ntchito makamaka popanga mitundu yosiyanasiyana yamagetsi yotchinga magetsi, matabwa ozungulira osindikizidwa, matupi agalimoto, akasinja osungira, mabwato, nkhungu, ndi zina. Nsalu zagalasi zapakatikati-alkali zimagwiritsidwa ntchito makamaka popanga nsalu zokutira za pulasitiki komanso ntchito zolimbana ndi dzimbiri. Makhalidwe a nsaluyo amatsimikiziridwa ndi katundu wa ulusi, kachulukidwe ka Warp ndi weft, kapangidwe ka ulusi, ndi mawonekedwe a weave. Kachulukidwe ka ulusi ndi ulusi umatsimikiziridwa ndi kapangidwe ka ulusi ndi kapangidwe ka nsalu. Kuphatikizika kwa kachulukidwe ka ulusi ndi ulusi ndi kapangidwe ka ulusi kumatsimikizira momwe nsaluyo imakhalira, monga kulemera, makulidwe, ndi kusweka mphamvu. Pali mitundu isanu yoluka yoluka: yosalala (yofanana ndi yowomba), twill (nthawi zambiri ± 45 °), satin (yofanana ndi nsalu ya unidirectional), leno (zoluka zazikulu zamagalasi a fiber mesh), ndi matts (ofanana ndi nsalu ya oxford).

2.Glass Fiber TapeAgawika mu tepi yoluka-m'mphepete (m'mphepete mwake) ndi tepi yopanda m'mphepete (m'mphepete mwake). Njira yayikulu yoluka ndi yomveka. Tepi yamagalasi yopanda alkali imagwiritsidwa ntchito popanga zida zamagetsi zomwe zimafunikira mphamvu zambiri komanso zida zabwino za dielectric.

3.Glass Fiber Unidirectional Fabric

•  Unidirectional Warp Fabricndi nsalu ya satin yosweka ya zingwe zinayi kapena nsalu zazitali za satin zoluka ndi ulusi wolimba kwambiri komanso ulusi wabwino kwambiri. Mawonekedwe ake ndi amphamvu kwambiri makamaka panjira yozungulira (0 °).
• PalinsoGlass Fiber Unidirectional Weft Fabric, yomwe imapezeka mumitundu yonse yolukidwa ndi mikwingwirima. Amadziwika ndi ulusi wokhotakhota komanso ulusi wabwino kwambiri, wokhala ndi ulusi wagalasi womwe umalunjika ku ma weft, womwe umapereka mphamvu kwambiri pamayendedwe a weft (90 °).

4.Glass Fiber 3D Fabric (Stereoscopic Fabric)Nsalu za 3D zimagwirizana ndi nsalu za planar. Mapangidwe awo asintha kuchokera ku mbali imodzi ndi ziwiri mpaka zitatu, zomwe zimapatsa zida zophatikizika zomwe zimalimbikitsidwa ndi iwo kukhulupirika kwabwino komanso kufananiza, kuwongolera kwambiri mphamvu yakumeta ubweya wa interlaminar ndi kulekerera kuwonongeka kwa zophatikizika. Anapangidwa kuti akwaniritse zosowa zapadera za gawo lazamlengalenga, ndege, zida, ndi zapamadzi, ndipo ntchito yawo tsopano yakula ndikuphatikiza magalimoto, zamasewera, ndi zida zamankhwala. Pali magulu asanu akuluakulu: nsalu za 3D, zoluka za 3D, nsalu za orthogonal komanso zopanda orthogonal zopanda crimp 3D, nsalu zolukidwa za 3D, ndi mitundu ina ya nsalu za 3D. Mawonekedwe a nsalu za 3D amaphatikizapo block, columnar, tubular, hollow truncated cone, ndi makulidwe osinthika amitundu yosiyanasiyana.

5.Glass Fiber Preform Nsalu (Nsalu Zowoneka)Maonekedwe a nsalu za preform ndi ofanana kwambiri ndi mawonekedwe a chinthu chomwe amapangira kuti azilimbitsa, ndipo ayenera kuluka pamipando yodzipereka. Nsalu zooneka ngati symmetric zikuphatikizapo: zipewa zozungulira, ma cones, zipewa, nsalu zooneka ngati dumbbell, ndi zina zotero. Zowoneka ngati mabokosi ndi mabwato amatha kupangidwanso.

6.Nsalu ya Glass Fiber Core (Nsalu Yosokera Mozama)Nsalu yapakati imakhala ndi zigawo ziwiri zofanana za nsalu zolumikizidwa ndi mizere yolunjika yotalika. Mawonekedwe ake apakati amatha kukhala katatu, amakona anayi, kapena zisa.

7.Nsalu Zolukidwa ndi Glass Fiber Stitch (Knitted Mat kapena Woven Mat)Ndizosiyana ndi nsalu wamba komanso kuchokera kumalingaliro achizolowezi a mat. Nsalu yomangika kwambiri imapangidwa pokuta ulusi umodzi wa ulusi wokhotakhota ndi wosanjikiza umodzi wa ulusi wokhotakhota, ndiyeno kuulumikiza pamodzi kuti apange nsalu. Ubwino wa nsalu zomangika ndi:

• Ikhoza kuonjezera mphamvu yowonjezereka, mphamvu zotsutsana ndi delamination pansi pa zovuta, ndi mphamvu zosinthika za FRP laminates.
• Amachepetsa kulemera kwaZogulitsa za FRP.
• Malo osalala amapangitsa kuti FRP ikhale yosalala.
• Zimathandizira kuyika mmwamba ntchito ndikuwonjezera zokolola zantchito. Izi kulimbikitsa zinthu akhoza m'malo CFM mu pultruded FRP ndi RTM, komanso akhoza m'malo analuka roving mu centrifugal kuponyedwa FRP chitoliro kupanga.
