Fiberglass Surface Veil: Nws Ua Dab Tsi thiab Yuav Ua Li Cas Xaiv Qhov Hnyav GSM Rau FRP Projects

Yog tias koj tau raug qhia tias daim ntaub thaiv saum npoo yog "xaiv tau" - lossis, ntawm qhov tod tes, tias nws yuav hloov lub zog ntawm koj lub laminate - ob qho lus hais tsis meej txog qhov txheej nyias nyias no yog rau dab tsi. Daim ntaub thaiv saum npoo fiberglass (kuj muag ua cov ntaub so ntswg saum npoo lossis daim lev saum npoo) yog ib txheej ua haujlwm, tsis yog txheej txhawb zog. Nws ua peb txoj haujlwm tshwj xeeb ntawm qhov chaw ntawm FRP, nws tsis ua haujlwm thauj khoom ntawm daim lev txiav lossis woven roving, thiab kev paub txog txoj haujlwm twg koj xav tau yog qhov qhia rau koj tias qhov hnyav twg thiab cov khoom twg yuav tsum xaj. Phau ntawv qhia no taug kev los ntawm cov haujlwm ntawd, qhov hnyav uas koom nrog, thiab cov lus nug uas yuav tsum teb ua ntej koj tso RFQ.

Fiberglass Surface Veil: Nws Ua Dab Tsi thiab Yuav Ua Li Cas Xaiv Qhov Hnyav Yog

Ib daim ntaub thaiv saum npoo yog ib daim lev uas ua los ntawm cov iav fibers zoo heev - Ruifiber raug kos ntawm 3.5–6 microns - tuav hauv ib lub binder sib zog, hnyav ntawm 20 thiab 90 g / m². Qhov ntawd yog qhov sib dua li cov lev txiav thiab cov khaubncaws sab nraud povtseg hauv qab nws, thiab qhov sib dua ntawd yog qhov taw tes: nws tsis nyob ntawd los ntxiv lub zog, nws nyob ntawd los tswj qhov chaw ntawm koj qhov zoo li cas thiab nws ua li cas. Peb txoj haujlwm npog yuav luag txhua qhov kev siv.

Txoj Haujlwm 1: zais cov qauv txhawb nqa.Cov xov paj loj los ntawm cov txheej hauv qab no feem ntau "luam tawm" ib txheej gel lossis txheej sab saud, tawm hauv cov qauv woven lossis matted me ntsis ntawm qhov chaw tiav. Ib txheej veil saturates nrog resin thiab tsim ib daim nyias nyias, fiber ntau, resin-nplua nuj stratum uas npog qhov texture ntawd, yog li lub ntsej muag tiav nyeem du thiab sib xws. Thaum txoj haujlwm no raug hla lossis daim ntaub thaiv yog sib dua rau cov qauv hauv qab, koj pom nws: cov qauv dab hauv lub tsho gel tom qab xuab zeb lossis weathering.

Txoj Haujlwm 2: txhawb nqa ib qho kev thaiv xeb.Hauv cov thoob dej, cov kav dej thiab cov ntaub, qhov kev tiv thaiv xeb ntawm qhov tsis yog los ntawm daim ntaub thaiv nws tus kheej - nws los ntawm lub kaw lus resin. Qhov uas daim ntaub thaiv ua yog nqa thiab txhawb nqa cov ntaub sab hauv uas muaj cov resin ntau: cov fibers zoo tuav cov resin ntau heev ntawm qhov chaw, ua rau cov txheej txheem tshuaj lom neeg tuab thiab kev ncaj ncees uas nws xav tau. Qhov kev tiv thaiv kev ua tau zoo yog txiav txim siab los ntawm cov resin uas koj ua ke nrog nws. Thaum txoj haujlwm no ua tsis zoo, blistering thiab thaum ntxov liner tawg ntawm lub ntsej muag tshuaj lom neeg yog cov tsos mob ib txwm muaj.

Txoj Haujlwm 3: ua kom ruaj khov ntawm kev tsim khoom.Ntawm cov kab pultrusion thiab hauv kev ua haujlwm molding rov ua dua, daim ntaub thaiv ntawm sab nraud muab cov txheej txheem ib qho chaw sib xws, kwv yees tau qhov chaw ua haujlwm tawm tsam: nws txo cov qauv fibers ntawm cov profiles pultruded, thiab nws ua rau qhov zoo ntawm qhov chaw rov ua dua los ntawm ib pawg mus rau ib pawg es tsis yog nyob ntawm seb tus neeg teb xov tooj kawg tso lub lev li cas. Thaum qhov chaw tsim khoom tsis sib xws, qhov tsos mob yog qhov sib txawv ntawm cov khoom uas tau pwm zoo ib yam.

Nws TSIS UA LI CAS

Ob qho kev piav qhia meej txuag cov neeg yuav khoom cov nyiaj tiag tiag, vim tias ob qho kev nkag siab yuam kev ua rau kev yuav khoom tsis raug.

Nws tsis nqa cov khoom hnyav.Daim ntaub thaiv 30 g/m² tsis muaj dab tsi pab txhawb rau qhov tawv lossis lub zog ntawm daim ntaub laminate; cov qauv los ntawm cov txheej txiav thiab cov ntaub woven. Hauv peb cov npe khoom peb piav qhia txog daim ntaub thaiv saum npoo av ua rau qhov zoo ntawm qhov chaw, kev tiv thaiv xeb thiab kev ruaj khov ntawm qhov tiav lawm - nyeem qhov ntawd ua rau qhov ruaj khov ntawm qhov chaw, tsis yog kev txhawb nqa cov qauv. Yog tias daim ntaub laminate xav tau lub zog, cov lus teb yog CSM ntau dua lossis zoo dua thiab woven roving, tsis yog daim ntaub thaiv hnyav dua. (Yog tias koj tab tom txiav txim siab ntawm cov txheej txheem, saib peb phau ntawv qhia rau chopped strand lev vs woven roving.)

Nws tsis ua rau lub laminate tiv taus tshuaj lom neeg.Qhov no yog qhov feem ntau tshaj plaws uas cog lus tias yuav ua tsis tau zoo. Lub ntaub thaiv txhawb nqa cov txheej txheej uas muaj cov roj hmab ntau uas tiv taus tshuaj lom neeg; qhov tseeb tiv taus koj cov tshuaj tshwj xeeb, ntawm koj qhov kub tshwj xeeb, yog ib qho khoom ntawm lub cev roj hmab thiab kev tsim qauv tag nrho. Lub ntaub thaiv uas tau teev tseg kom raug tseem ua tsis tau zoo yog tias cov roj hmab tom qab nws tsis raug rau cov xov xwm.

Kuj tseem muaj ib rooj plaub raug cai rau kev hla nws. Qhov twg ib lub ntsej muag tsis tau pom, tsis tau so, thiab tsis nqa cov tshuaj lom neeg - sab nraub qaum ntawm lub vaj huam sib luag, lub flange sab hauv, ib lub tav zais - daim ntaub thaiv ntxiv cov nqi khoom siv thiab ib kauj ruam tso yam tsis ntxiv dab tsi uas qhov khoom xav tau. Hom kev ua tsis tiav tsis yog siv daim ntaub thaiv; nws yog siv ib qho los ntawm kev coj ua ntawm cov ntsej muag uas tsis muaj ib qho ntawm nws peb txoj haujlwm siv tau, lossis tshem nws ntawm lub ntsej muag uas ib qho ntawm lawv ua. Tshawb xyuas txhua lub ntsej muag ntawm qhov khoom tawm tsam peb txoj haujlwm saum toj no thiab cia qhov ntawd txiav txim siab.

Daim ntaub thaiv vs cov ntaub pua plag txiav

Vim tias ob qho tib si yog cov lev random-fiber, ob qho tib si tau tsis meej pem. Qhov txawv yog qhov hnyav thiab lub luag haujlwm:

	Daim ntaub thaiv nto	Cov ntaub pua plag txiav
Qhov hnyav	20–90 g/m²	100–900 g/m²
Qhov zoo ntawm cov fiber	zoo heev (3.5–6 μm hauv Ruifiber's series)	cov xov txiav
Lub luag haujlwm	Kev ua haujlwm ntawm qhov chaw: du, txhawb nqa liner, kev ruaj khov ntawm cov txheej txheem	kev faib tawm ntau thiab kev txhawb nqa
Txoj Haujlwm	sab nraud tshaj plaws, feem ntau tawm tsam pwm lossis xov xwm	lub hauv paus ntawm lub laminate

Cov lus qhia: cov neeg muag khoom siv "surface veil", "surface tissue" thiab "surfacing mat" rau tib hom khoom. Piv los ntawm cov qauv thiab qhov hnyav, tsis yog los ntawm lub npe.

Ob yam khoom no yog cov khoom sib ntxiv, tsis yog lwm txoj hauv kev: ib qho txheej tiv thaiv xeb ib txwm muaj ib txheej gel, tom qab ntawd ib daim ntaub thaiv, tom qab ntawdCSMcov plies — daim ntaub thaiv muab qhov ua haujlwm ntawm qhov chaw thaum CSM tsim cov tuab thiab lub zog.

Xaiv qhov hnyav

Ruifiber'sqhov ntau ntawm daim ntaub thaiv qhov chawkhiav ntawm 20 txog 90 g / m², hauv cov koob teeb tsa rau tes tso, filament winding thiab pultrusion. Hauv qhov ntau ntawd, kev coj ua lag luam pawg qhov hnyav los ntawm kev siv zoo li no (qhov no yog kev coj ua ib txwm muaj thoob plaws cov neeg muag khoom, tsis yog Ruifiber-specific datasheet - paub meej tias qhov kev xaiv kawg nrog koj tus neeg muag khoom):

Qhov hnyav	Tus cwj pwm ib txwm muaj	Haum thaum
~20 g/m²	sib dua, yooj yim hloov pauv tshaj plaws	cov pwm nyuaj lossis nruj-curvature qhov twg daim ntaub thaiv yuav tsum ua raws li cov duab
~30 g/m²	band nruab nrab dav dav	feem ntau cov khoom siv pleev kom zoo nkauj thiab cov txheej txheem txheem; qhov pib sib xws
~50 g/m² thiab siab dua	txheej txheej nplua nuj dua	cov ntsej muag thiab cov khoom siv tshuaj lom neeg hnyav dua uas xav tau ib txheej tiv thaiv zoo dua

Peb lub cim qhia thawb koj ib txoj hlua mus rau saum: cov tshuaj lom neeg uas muaj zog heev ntawm lub ntsej muag ua haujlwm, cov qauv txhawb nqa ntxhib hauv qab uas lub ntsej muag sib dua yuav tsis npog, thiab cov chaw tiaj tus lossis qhib qhov twg kev sib haum xeeb tsis tseem ceeb. Ob qho rub koj mus rau hauv qab: cov duab puab thiab cov pwm me me, thiab cov chaw zoo nkauj uas koj xav tau tsawg kawg nkaus ntawm cov fiber ntawm lub ntsej muag.

Ib qho lus qhia tseem ceeb txog kev tuav: qhov hnyav sib dua yog qhov nyuaj heev. Daim ntaub thaiv 20 g/m² yooj yim dua thaum txiav thiab muab tso dua li txheej 50 g/m², yog li cov khw tshiab rau daim ntaub thaiv qee zaum xaj hnyav "kom muaj kev nyab xeeb" thiab tom qab ntawd pom tias txheej hnyav dua nyuaj rau ua kom haum. Yog tias koj pab neeg tab tom tuav cov khoom siv thawj zaug, nws tsim nyog xaj me me ntawm ob qhov hnyav sib ze thiab khiav lawv ntawm lub vaj huam sib luag ua ntej txiav txim siab tag nrho.

Xaiv los ntawm cov txheej txheem: tes tso, winding, pultrusion

Qhov no yog qhov uas cov khoom lag luam ntawm tus neeg muag khoom tseem ceeb dua li daim ntawv qhia txog cov ntaub ntawv dav dav. Ruifiber faib nws daim ntaub thaiv saum npoo ua peb series kom phim peb txoj kev uas feem ntau cov neeg yuav khoom siv:

Cov koob	Ua rau	Dab tsi yog daim ntaub thaiv ua nyob ntawd
Kev tso tes	kev sib cuag molding tawm tsam qhov chaw pwm	ua haujlwm ua daim tawv nqaij hla lub tsho gel, ua kom du thiab tsim lub liner
Kev sib txuas ntawm cov xov hlau	cov khoom cylindrical - cov kav dej, cov tank, cov hlab ntsha	qhwv ua ib feem ntawm cov kab ke liner ntawm qhov chaw xov xwm
Pultrusion	cov qauv txuas ntxiv mus	qhwv ib ncig ntawm qhov profile ua ntej lub pwm; kho kom zoo nkauj rau hauv daim tawv nqaij sab nraud du dua nrog tsawg dua cov fibers uas raug nthuav tawm - feem ntau ntawm cov ces kaum, cov channel, cov pas nrig, cov khoom ntaiv

Ib qho lus qhia txog kev xaiv polyester veil: Ruifiber kuj muaj cov polyester version hauv nws cov kab veil combo stitch lev; cov fiberglass version yog qhov chaw rau cov ntawv thov uas xav tau hluav taws kub dua thiab tiv taus cua sov dua li cov polyester variant. Rau kev yuav khoom ntawm cov ntaub thaiv saum npoo, iav yog lub neej ntawd; nug txog polyester tsuas yog tias koj daim ntawv thov tshwj xeeb hu rau nws.

Yuav tsum paub meej dab tsi ua ntej koj xaj khoom

Ib daim RFQ uas tau txais ib daim ntawv hais txog kev huv si es tsis yog peb zaug ntawm kev piav qhia muaj tsib daim teb:

1. Lub luag haujlwm laminate— lub ntsej muag zoo nkauj, lub txheej tiv thaiv xeb, lub ntsej muag tiv thaiv huab cua, lossis cov txheej txheem stabilizer. Qhov no tsav txhua yam lwm yam.
2. Qhov hnyav thiab dav— piv txwv li 30 g/m², 1,000 mm yob. Muab qhov ntau thiab qhov kev cia siab rau kev kam rau siab es tsis txhob muab ib tus lej xwb yog tias koj hloov tau yooj yim.
3. Kev sib raug zoo ntawm cov ntawv nplaum thiab koj cov resin— cov binder yuav tsum yaj kom raug hauv koj lub cev resin (polyester, vinyl ester, epoxy). Qhia rau tus neeg muag khoom cov resin; hais kom lawv phim cov binder.
4. Txheej Txheem— tes tso, winding lossis pultrusion, yog li koj tau hais cov koob zoo.
5. Kev tshuaj lom neeg ntawm iav thiab kev kuaj kev lees txais— nug seb daim ntaub thaiv no yog kos los ntawm hom iav twg thiab koj tuaj yeem qhia meej txog cov kev ntsuam xyuas twg (qhov hnyav ib cheeb tsam, kev yaj ntawm cov khoom sib txuas).

Cov Lus Nug Feem Ntau

Puas yog daim ntaub thaiv saum npoo av muaj qauv?

Tsis yog. Nws pab txhawb rau qhov ruaj khov thiab zoo ntawm qhov chaw, tab sis lub zog ntawm cov qauv yog los ntawm cov txheej txheem txhawb nqa uas raug txiav thiab xaws hauv cov laminate.
