Mhando Dzakajairwa dzeGirazi Fiber Mats neMicheka

Girazi Fiber Mats

1.Yakachekwa Strand Mat (CSM)Girazi fiber roving(dzimwe nguva zvakare inoenderera mberi roving) inochekwa kuita 50mm kureba, zvisina tsarukano asi zvakafanana yakaiswa pa conveyor mesh bhandi. Emulsion binder inobva yaiswa, kana kuti poda binder inoputirwa pairi, uye zvinhu zvacho zvinopiswa uye zvinoporeswa kuti zvigadzire tambo yakachekwa. CSM inonyanya kushandiswa mukuisa-kumusoro kwemaoko, kuenderera mberi kwekugadzira mapaneru, inofananidzwa nekufa kuumba, uye SMC (Sheet Molding Compound) maitiro. Hunhu hunodiwa kuCSM zvinosanganisira:

• Uniform nzvimbo huremu pahupamhi.
• Kugovera kwakafanana kwetambo dzakachekwa pamusoro pemeti pasina mavhodhi makuru, uye yunifomu binder kugovera.
• Pakati nepakati yakaoma mat simba.
• Yakanakisa resin wetting uye yekupinda zvivakwa.

2.Inoenderera mberi Filament Mat (CFM)Mafilamende egirazi anoenderera mberi akaumbwa panguva yekudhirowa kana kusunungurwa kubva pamapakeji ekutenderera anoiswa pasi mumufananidzo-sere patani painoramba ichifamba mesh bhandi uye inosungirirwa nehupfu binder. Sezvo mafiber ari muCFM achienderera mberi, anopa kusimbiswa kuri nani kune zvakaumbwa zvinhu kupfuura CSM. Iyo inonyanya kushandiswa mu pultrusion, RTM (Resin Transfer Molding), kumanikidza bhegi kuumba, uye GMT (Glass Mat Reinforced Thermoplastics) maitiro.

3.Surfacing MatFRP (Fiber Reinforced Plastic) zvigadzirwa zvinowanzoda resin-rich surface layer, iyo inowanzoitwa nepakati-alkali girazi (C-girazi) pamusoro pemeti. Sezvo iyi meti inogadzirwa kubva kuC-girazi, inopa iyo FRP nemakemikari kuramba, kunyanya acid kuramba. Pamusoro pezvo, nekuda kwehutete hwayo uye dhayamita yefayibha yakatsetseka, inogona kutora resin yakawanda kugadzira resin-yakapfuma dhizaini, inovhara magadzirirwo egirazi fiber reinforcing zvinhu (seyakarukwa roving) uye kushanda seyepamusoro pekupedzisira.

4.Inodiwa MatInogona kuiswa muYakachekwa Fiber Inodiwa Mat uye Inoenderera Filament Inodiwa Mat.

•  Yakachekwa Fiber Inodiwa Matinogadzirwa nekuchekera girazi faibha roving kuita 50mm kureba, kugadzika zvisina tsarukano pane substrate yakamboiswa pabhandi rekutakura, uye wozoishongedza netsono dzine minzwa. Tsono dzinosundira shinda dzakachekwa musubstrate, uye mabhabhu anounzawo mamwe mafiibhi kumusoro, achigadzira chimiro chemativi matatu. Iyo substrate inoshandiswa inogona kuve yakasununguka yakarukwa jira regirazi kana mamwe mafiber. Rudzi urwu rwemeti inodikamwa ine manzwiro-akaita. Kunyanya kushandiswa kwayo kunosanganisira thermal uye acoustic insulation zvinhu, lining zvinhu, uye kusefa zvinhu. Inogona zvakare kushandiswa mukugadzirwa kweFRP, asi iyo inokonzeresa FRP ine yakaderera simba uye shoma application scope.
•  Inoenderera Filament Inodiwa Matinogadzirwa nekukandira zvisina tsarukano magirazi efilaments pabhandi remambure rinoramba richishandiswa uchishandisa shinda yekuparadzira filament, ichiteverwa nekunokora nebhodhi retsono kugadzira meti ine yakarukwa matatu-dimensional fiber chimiro. Iyi mat inonyanya kushandiswa mukugadzirwa kwegirazi fiber yakasimbiswa thermoplastic stampable sheets.

5.Stitched MatFiber dzegirazi dzakachekwa dzinobva pa50mm kusvika 60cm pakureba dzinogona kusonanidzwa pamwe chete nemuchina wekusonesa kuita tambo yakachekwa kana kuti refu fiber mat. Iyo yekutanga inogona kutsiva yechinyakare binder-yakasungwa CSM mune mamwe maapplication, uye iyo yekupedzisira inogona, kusvika pamwero wakati, kutsiva CFM. Zvavanowanzo kanakira kusavapo kwezvisungo, kudzivirira kusvibiswa panguva yekugadzira, yakanaka resin impregnation kuita, uye mutengo wakaderera.

Girazi Fiber Micheka

Zvinotevera zvinosuma machira akasiyana egirazi fiber akarukwa kubvagirazi fiber shinda.

1.Glass MuchekaGirazi jira rinogadzirwa muChina rakakamurwa kuva alkali-isina (E-girazi) uye yepakati-alkali (C-girazi) marudzi; kugadzirwa kwakawanda kwekunze kunoshandisa E-GLASS alkali-isina girazi jira. Girazi jira rinonyanya kushandiswa kugadzira akasiyana emagetsi insulating laminates, akadhindwa ematunhu mabhodhi, mitumbi yemotokari, matangi ekuchengetera, mabhoti, molds, etc. Medium-alkali girazi jira rinonyanya kushandiswa kugadzira epurasitiki-coated packaging machira uye kune corrosion-resistant application. Hunhu hwejira hunotarwa nefiber properties, warp uye weft density, shinda yekugadzira, uye weave pattern. Warp uye weft density inotarirwa neshinda yekugadzira uye weave pattern. Iko kusanganiswa kwewarp uye weft density uye shinda dhizaini inotaridza chimiro chemuviri wejira, sehuremu, ukobvu, uye kuputsa simba. Kune mashanu ekutanga mapeteni ekuruka: yakajeka (yakafanana neyakarukwa roving), twill (kazhinji ± 45 °), satin (yakafanana nemucheka unidirectional), leno (main weave yegirazi fiber mesh), uye matts (akafanana nemucheka weoxford).

2.Girazi Fiber TapeYakakamurwa kuita yakarukwa-kumucheto tepi (selvage edge) uye isiri-yakarukwa-yemupendero tepi (yakaputsika mupendero). Mutsara mukuru wekurukwa wakajeka. Alkali-isina girazi fiber tepi inowanzo shandiswa kugadzira zvigadzirwa zvemagetsi zvinoda simba rakakura uye yakanaka dielectric zvivakwa.

3.Girazi Fiber Unidirectional Fabric

•  Unidirectional Warp Fabricijira rechina rakatyoka resatin kana kuti refu-shaft satin weave jira rakarukwa neshinda dzakakasharara neshinda dzakatsetseka. Hunhu hwayo isimba repamusoro kunyanya munzira yewarp (0 °).
• Kune zvakareGirazi Fiber Unidirectional Weft Fabric, inowanikwa mumhando dzose dziri mbiri dzakarukwa uye dzakarukwa. Iyo inoratidzwa neshinda dzakakasharara uye shinda dzakatsetseka, iine girazi faibha warn dzakatariswa zvakanyanya munzira yeweft, ichipa simba rakakwirira munzira yewe weft (90 °).

4.Girazi Fiber 3D Fabric (Stereoscopic Fabric)Machira e3D ane hukama nemachira akarongwa. Mamiriro avo ekuumbwa akashanduka kubva kune imwe-dimensional uye maviri-dimensional kusvika kune matatu-dimensional, ichipa iyo inoumbwa zvinhu zvakasimbiswa navo kuvimbika kwakanaka uye kuenderana, zvakanyanya kuvandudza iyo interlaminar shear simba uye kurwisa-kukuvadza kushivirira kweanosanganisa. Iwo akagadziridzwa kuti asangane nezvinodiwa zvakakosha zveaerospace, zvendege, zvombo, uye zvemugungwa, uye kushanda kwavo kwawedzera kusanganisa mota, zvinhu zvemitambo, uye zvekurapa. Kune zvikamu zvishanu zvikuru: machira akarukwa e3D, akarukwa machira e3D, orthogonal uye asiri-orthogonal asiri-crimp 3D machira, 3D akarukwa machira, uye mamwe marudzi emachira e3D. Maumbirwo emachira e3D anosanganisira block, columnar, tubular, hollow truncated cone, uye kusiyanisa-ukobvu husina kujairika muchinjiko-zvikamu.

5.Glass Fiber Preform Fabric (Mucheka Wakaumbwa)Chimiro chemicheka yepreform yakafanana nechimiro chechigadzirwa chavanoda kusimbisa, uye vanofanirwa kurukwa pazvirukwa zvakatsaurirwa. Machira ane symmetrical shaped anosanganisira: spherical caps, makoni, heti, machira akaita sedumbbell, etc. Asymmetrical shapes semabhokisi uye zvikepe zvezvikepe zvinogonawo kugadzirwa.

6.Girazi Fiber Core Fabric (Kuburikidza-Kukobvu Kusona Mucheka)Core jira rine maviri anoenderana akaturikidzana ejira akabatanidzwa nelongitudinal vertical strips. Chimiro chayo chemuchinjiko chinogona kuva chetriangular, rectangular, kana muzinga weuchi.

7.Girazi Fiber Stitch-Bonded Fab (Knitted Mat kana Woven Mat)Yakasiyana nemachira akajairika uye kubva kune yakajairika pfungwa yemat. Mucheka wakakoshwa wakanyanya kusona unoumbwa nekufukidza rumwe rutivi rweshinda yewarp nerumwe rutivi rweshinda, wobva waabatanidza pamwechete kuita jira. Zvakanakira zvemicheka-yakasungwa machira anosanganisira:

• Inogona kuwedzera iyo yekupedzisira kusimba simba, anti-delamination simba pasi pekunetseka, uye kuchinjika simba reFRP laminates.
• Inoderedza huremu hweFRP zvigadzirwa.
• Iyo yakadzikama inoita kuti iyo FRP pamusoro iite zvakanaka.
• Inorerutsa basa rekuisa-kumusoro kwemaoko uye inovandudza basa revashandi. Izvi zvinosimbisa zvinhu zvinogona kutsiva CFM mune pultruded FRP uye RTM, uye inogona zvakare kutsiva yakarukwa roving mu centrifugal kukandira FRP pombi kugadzirwa.
