Cov iav iav yog ntau yam thiab siv tau cov khoom siv rov ua dua tshiab uas tshwj xeeb rau cov neeg siv khoom xav tau. Los ntawm cov khoom siv ntawm kab lus no, koj yuav kawm paub tias nws yog dab tsi, nws yog dab tsi, nws siv nyob qhov twg thiab nws txawv li cas ntawm cov iav fiberglass.

Nws yog dab tsi thiab nws txawv li cas ntawm fiberglass?

Cov iav iav - ib daim ntawv ntawm cov iav fiberglass (sib npaug faib cov fiberglass xov) 5 cm lossis ntev dua, txuas nrog cov nplaum puag. Nws yog cov khoom siv dawb (uas tsim nyog rau tha xim), nws tau sib xws nrog polyester, epoxy, vinyl ester resin. Nws yog ntau yam kev ua haujlwm, eco-phooj ywg, ruaj khov, hnyav, tsis muaj dej, tiv tshav kub. Iav lev - txhawb cov khoom yas . Nws muaj peev xwm ua txhua yam tsim nyog, haum rau kev ua cov tshuab. Nws cov khoom yog vim nws cov qauv thiab muaj pes tsawg leeg. Cov khoom siv no tiv taus kab mob, kis kab mob fungal, pwm, nws cov iav hauv xov yog yoog raws. Tus so ntawm cov yas yog muab los ntawm cov qauv ntawm lub lev.

Cov iav fiberglass tuaj yeem ua rau lub qhov txhab thiab cua tuaj yeem nyem tawm ntawm nws . Nws tau tsim hauv yob 125 cm dav. Tus nqi ntawm cov khoom yog nyob ntawm nws qhov ntom thiab hom, yog li nws txawv ntawm 200 txog 900 rubles rau ib lub ntsuas ntsuas. Txawm li cas los xij, nws kuj tuaj yeem nyob ntawm qhov hnyav.

Cov iav iav txawv ntawm fiberglass hauv cov qauv . Fiberglass yog cov ntaub ntawm cov xov sib txuas, nws tau los ntawm kev xaws. Cov iav iav yog cov ntaub fiberglass, cov fibers uas tsis cuam tshuam nrog, tab sis txuas nrog los ntawm polymer matrix. Qee lub sij hawm nws muaj cov qauv ntawm cov zom ua ntu ntu sib txawv. Cov qauv ntawm cov txheej txheem txuas ntxiv ntawm fiberglass tau xaj.

Qhov sib txawv ntawm cov ntaub ntawv nyob hauv hom kev thov thiab tus lej txheej . Cov ntaub iav tau hloov kho ua ntej siv (piv txwv li, ua kom tsis huv nrog epoxy resin). Fiberglass lev tau npaj txhij siv. Nws tuaj yeem suav nrog ntau txheej, thaum fiberglass tsuas muaj 1 txheej.

Daim ntawv tso tawm kuj txawv. Fiberglass yog ib hom yob cov khoom siv . Fiberglass mats tsis yog muag nkaus xwb hauv yob, tab sis kuj yog hauv daim ntawv ntawm cov tuab sib txawv thiab tuab. Cov iav fiber ntau yog tuab thiab tawv dua.

Hais txog cov yam ntxwv ntawm lub cev thiab lub cev, nws zoo dua li fiberglass. Nws yog siv los teev cov tuab thiab lub zog ntawm lub hauv paus ntawm cov khoom.

Kev siv tshuab ntau lawm

Kev tsim cov iav fiberglass muaj ntau txoj hauv kev. Cov iav xov tau muab tso rau ntawm lub tshuab thauj khoom, tom qab ntawd lub cuab yeej tau qhib, thiab thaum lub sijhawm txav mus los ib lub thawv ntawv polymer tau txuas ntxiv siv rau lawv . Tom qab ntawd, cov fiber ntau xa mus rau qhov cub kom qhuav. Tom qab ntawd nws yog dov. Cov viscosity ntawm cov kua polymer siv thaum siv rau cov fibers yog li 40 mPa * s. Hom polymer yog lub luag haujlwm rau kev ncaj ncees ntawm lub lev. Yog li ntawd, nws tau xaiv ntau dua rau hauv kev suav nrog cov tshuaj sib xyaw ntawm cov khoom yas, nws lub zog yuav tsum tau nce los ntawm iav lev.

Qhov kev xaiv ntau tshaj plaws ntawm phau ntawv polymer yog txiav txim siab polyester cob … Nws tau sib xyaw ua ke hauv cov kua ua kom nrawm thiab cov tshuaj tiv thaiv. Tom qab lawv pib polymerization.

Yog tias txoj haujlwm siv epoxy cob , ua ntej npaj cov kua nplaum hauv qhov sib npaug. Tom qab ntawd daim iav lev tau sib txuas rau cov kua nplaum. Qhov hnyav tau sib xyaw zoo, tom qab uas nws tau muab tso rau hauv daim ntawv tshwj xeeb thiab sab laug kom tawv rau ob peb teev. Txog thaum daim lev qhuav, nws yuav tsum tsis txhob kov. Siv txhuam txhuam los yog cov menyuam kom tshem cov npuas. Hauv kev ua haujlwm nws yog qhov zoo dua los siv hnab looj tes phais: lawv pheej yig thiab haum zoo ntawm tes.

Saib

Cov iav iav sib txawv hauv cov hom xov paj uas siv, uas tau txaws thiab cov khoom siv tseem ceeb. Qhov sib txawv ntawm lawv yog vim tus qauv. Fibers ntawm hom thib ob yog softer thiab ntau ywj, txhoov - nyuab dua thiab tawv dua. Cov ntaub pua plag fiberglass zoo yog tsim los ntawm cov khoom siv zoo ib puag ncig . Nws yog refractory, npaj tau yooj yim nrog cov resins thiab siv zog tso cov pa cua thaum ua. Nyob ntawm qhov sib xyaw ua ke thiab ntom ntom, iav mats tau muab faib ua 3 hom. Txhua hom tsiaj nws muaj nws tus yam ntxwv.

Emulsion

Emulsion-type glass mats yog ua los ntawm cov iav sib txuas ua ke ntev txog 5 cm ntev, uas muaj alkali. Lawv tau ua ke nrog cov emulsion binder polymer. Kev ntom ntom sib txawv hauv qhov ntau ntawm 250-900 g / m2, lawv tau siv rau phau ntawv thiab kaw cov khoom lag luam fiberglass. Cov khoom tsim nrog cov khoom siv no ruaj khov, tiv taus cov khoom puas, tshuaj lom neeg thiab huab cua . Emulsion iav mats tau yooj yim draped, muaj qib siab ntawm adhesion, yooj yim siv, ntub sai thiab soaking. Tau tshaj polyester resins.

Hmoov

Hmoov iav fiber ntau mats yog tsim los ntawm E hom iav fibers (nrog cov ntsiab lus alkali tsawg). Thaum tsim khoom, lawv raug txiav, txiav thiab lo nrog cov hmoov nplua nuj. Hauv kev sib piv nrog cov lus sib piv yav dhau los, cov hmoov iav lev muaj cov qauv xoob thiab tsis yooj yim dua. Nws qhov ntom kuj tseem tsawg dua (nws txawv ntawm 100 txog 600 g / m2).

Vim yog cov txheej txheem nruj dua, cov hmoov hmoov tsawg dua thiab tsis ntxig rau hauv paus . Hauv kev ua haujlwm nrog nws, cov txheej txheem ntawm nias, nqus nqus dej, RMT thev naus laus zis tau siv. Nws yog qhov tsim nyog rau kev ua haujlwm nrog cov khoom lag luam loj ntawm cov duab yooj yim, hom du thiab pob tshab.

Ntev-fiber ntau

Cov lev no yog tus yam ntxwv ntawm nws txoj kev sib tshuam E (E-CR). Lawv tau teeb tsa hauv txheej, txuas nrog cov nplaum polymer. Qhov ntom ntawm cov khoom siv no tuaj yeem sib txawv ntawm 100 txog 900 g / m2. Nws tau siv hauv cov txheej txheem uas tawg vim xeb tsis suav nrog . Cov khoom txhawb ntxiv nrog nws yog ruaj khov rau cov neeg kho tshuab kev nyuaj siab.

Nws siv qhov twg?

Cov iav iav muaj ntau yam kev siv. Piv txwv li, rau nws lub hom phiaj kev tsim khoom, nws tau yuav los ua kom tuab dua. Thiab tseem nws tau siv hauv kev tsim kho txoj kev, tsev thiab vaj tsev ntawm ntau hom, hauv kev tsim nkoj thiab kev tsim kho tshuab. Nws muaj feem xyuam rau kev tsim khoom ntawm lub tsheb, piv txwv li, nrog nws txoj kev pab, ntu ntu sab hauv, lub qhov rooj thiab lub qhov rooj tau hloov kho tshiab. Qhov uas siv tau nyob ntawm qhov ntom ntom iav mats . Emulsion thiab hmoov hom khoom uas muaj qhov ntom ntawm 300, 450, 600, 900 g rau 1 sq. m tau siv hauv kev tsim cov ntim, cov kav dej, cov khoom hauv tsheb, nrog rau lwm yam khoom siv fiberglass.

Cov khoom sib xws nrog qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntaws (100, 150 g rau 1 sq. M) tau siv hauv kev tsim cov txheej txheem, txheej txheej sab hauv ntawm cov iav fiberglass ntim, cov kav dej, cov khoom siv kho kom zoo nkauj sab hauv . Piv txwv ntawm cov khoom lag luam uas siv iav mats yog lub nkoj, cov dej khov dej khov, cov kav dej, cov kav dej, cov npog, cov ntaub thaiv. Lawv tau siv los ua suab rwb thaiv tsev hauv cov mufflers thiab ua cov khoom siv rwb thaiv tsev cua sov.

Nrog cov cua sov sib npaug sib npaug nrog cov cua sov pom zoo, lawv siv sijhawm tsawg dua 2 zaug. Ib qho ntxiv, iav lev yog siv rau cov rooj sib tham, raws li kev txhawb nqa thaum nchuav hauv av. Lawv txhawb cov toj roob hauv pes, txhawb cov asphalt sib xyaw ua ke, ua cov ntim cov khib nyiab, tiv thaiv kev ua phem rooj zaum, tsev cog khoom thiab laj kab hauv av, yacht hulls los ntawm nws. Nws tsis nyuaj ua haujlwm nrog cov khoom siv.

Yuav khaws cia li cas?

Nws yog qhov tsim nyog los khaws iav mats hauv daim ntawv kaw hauv qhov chaw qhuav thiab txias. Yob tau ntim rau hauv hnab yas, ntxiv rau lawv tau ntim rau hauv cov thawv ntawv thawv. Cov thawv tau khaws cia ntsug lossis kab rov tav, nyob ntawm qhov loj me. Nws tau tso cai muab cov khoom me me rau ntawm cov loj.

Chav nyob uas cov iav mats tau khaws cia yuav tsum muaj cua nkag tau zoo . Koj tuaj yeem tshem cov khoom ntawm lub ntim tam sim ua ntej siv. Hauv qhov no, kua yuav tsum tsis pub tso rau hauv cov khoom. Thaum khaws cia hauv chav ntub, cov khoom poob nws qhov muaj txiaj ntsig.

Yog tias khaws cia kom zoo, cov iav fiberglass tuaj yeem khaws tau ntau xyoo.
