Chophimba cha Fiberglass Surface: Zimene Chimachita ndi Momwe Mungasankhire Kulemera Koyenera kwa GSM kwa Mapulojekiti a FRP

Ngati munauzidwapo kuti chophimba pamwamba ndi "chosankha" - kapena, kumbali ina, kuti chidzasintha mphamvu ya laminate yanu - mawu onsewa sakugwirizana ndi zomwe gawo lochepa lopanda ulusi ili limachita. Chophimba pamwamba cha fiberglass (chomwe chimagulitsidwanso ngati minofu ya pamwamba kapena mphasa yopangira pamwamba) ndi gawo logwira ntchito, osati gawo lolimbitsa. Chimagwira ntchito zitatu zapadera pamwamba pa gawo la FRP, sichigwira ntchito yonyamula katundu ngati mphasa yodulidwa kapena yoluka, ndipo kudziwa ntchito yomwe mukufuna ndi komwe kumakuuzani kulemera ndi mndandanda wazinthu zomwe muyenera kuyitanitsa. Bukuli limafotokoza ntchito zimenezo, kuchuluka kwa kulemera komwe kumakhudzidwa, ndi mafunso oti muyankhe musanayike RFQ.

Chophimba cha Fiberglass: Zimene Chimachita ndi Momwe Mungasankhire Kulemera Koyenera

Chophimba pamwamba ndi mphasa yopangidwa ndi ulusi wagalasi wabwino kwambiri — Ruifiber imakokedwa pa ma microns 3.5–6 — yosungidwa mu cholumikizira chopepuka, cholemera pakati pa 20 ndi 90 g/m². Chimenecho ndi chopepuka kwambiri kuposa mphasa wodulidwa ndi zigawo zolukidwa pansi pake, ndipo kupepuka kumeneko ndiye mfundo: sikofunikira kuwonjezera mphamvu, koma kulipo kuti kulamulire momwe pamwamba pa gawo lanu limawonekera komanso momwe limagwirira ntchito. Ntchito zitatu zimakhudza pafupifupi ntchito iliyonse.

Ntchito 1: kubisa kapangidwe kake kolimbitsa.Ulusi wopyapyala wochokera m'zigawo zomwe zili pansipa umakonda "kusindikiza" jeli kapena topcoat, ndikusiya mawonekedwe ofooka kapena opindika pamwamba pake. Chinsalu chotchinga chimadzaza ndi utomoni ndikupanga stratum yopyapyala, yokhala ndi utomoni wambiri, yokhala ndi utomoni wambiri yomwe imaphimba kapangidwe kake, kotero nkhope yomalizidwayo imakhala yosalala komanso yogwirizana. Ntchitoyi ikadumphadumpha kapena chophimbacho chili chopepuka kwambiri kuposa kapangidwe kake komwe kali pansi pake, mumachiwona: mawonekedwe amdima mu jeli pambuyo popukuta kapena kupukuta.

Ntchito 2: thandizani chotchinga dzimbiri.Mu matanki, mapaipi ndi zipilala, kukana dzimbiri kwa gawolo sikuchokera ku chophimba chokha - chimachokera ku dongosolo la utomoni. Chomwe chophimbacho chimachita ndikunyamula ndikuthandizira choyika mkati chokhala ndi utomoni wochuluka: ulusi wosalala umakhala ndi gawo lalikulu kwambiri la utomoni pamwamba, zomwe zimapangitsa kuti chotchinga cha mankhwala chikhale cholimba komanso cholimba chomwe chimafunikira. Mbiri yolimba imasankhidwa ndi utomoni womwe mumagwirizanitsa nawo. Ntchitoyi ikachitika molakwika, kutupa ndi kuwonongeka koyambirira kwa choyika pankhope ya mankhwala ndi zizindikiro zodziwika bwino.

Ntchito 3: kukhazikika pakupanga.Pa mizere yopukutira ndi ntchito yobwerezabwereza youmba, chophimba pamwamba pakunja chimapangitsa kuti ntchitoyi ikhale yofanana, yodziwikiratu kuti ingagwire ntchito: imachepetsa ulusi wowonekera pa ma profiles opukutira, ndipo imapangitsa kuti mawonekedwe a pamwamba akhale obwerezabwereza kuchokera pa gulu lina kupita ku lina m'malo modalira momwe wogwiritsa ntchito womaliza adayikira mphasa. Ngati mawonekedwe opangira sakugwirizana, chizindikiro chake ndi kusiyana pakati pa zigawo zomwe zidapangidwa mofanana.

Zimene sichichita

Kufotokozera zinthu ziwiri kumapulumutsa ogula ndalama zenizeni, chifukwa malingaliro onse olakwika amachititsa kuti agule zinthu molakwika.

Sichinyamula katundu womangira.Chophimba cha 30 g/m² sichimathandiza kwenikweni kulimba kapena kulimba kwa laminate; kapangidwe kake kamachokera ku zigawo zodulidwa ndi zolukidwa. Mu mndandanda wathu wazinthu timafotokoza chophimba cha pamwamba ngati chomwe chimapangitsa kuti pamwamba pakhale bwino, chitetezo cha dzimbiri komanso kulimba kwa gawo lomalizidwa - werengani zimenezo ngati chothandizira kulimba kwa pamwamba, osati ngati cholimbitsa kapangidwe kake. Ngati laminate ikufunika mphamvu, yankho lake ndi CSM yokhazikika bwino komanso yolukidwa bwino, osati chophimba cholemera kwambiri. (Ngati mukufuna kusankha pakati pa zigawo za kapangidwe kameneka, onani kalozera wathu wa mphasa yodulidwa ndi yolukidwa.)

Sizimapangitsa laminate kukhala yosagwira mankhwala.Iyi ndi njira yodziwika kwambiri yopezera zinthu zambiri. Chophimbacho chimathandizira utomoni wochuluka komwe kumakhala kukana mankhwala; kukana kwenikweni kwa mankhwala anu, pa kutentha kwanu, ndi chizindikiro cha dongosolo la utomoni ndi kapangidwe kake konse. Chophimba chomwe chatchulidwa bwino chimalephera kugwira ntchito ngati utomoni womwe uli kumbuyo kwake suli bwino pa cholumikizira.

Palinso chifukwa chovomerezeka chodumpha. Pamene nkhope siiwoneka, siipukutidwa, ndipo siinyamula mankhwala aliwonse — kumbuyo kwa gulu, flange yamkati, nthiti yobisika ya kapangidwe kake — chophimbacho chimawonjezera mtengo wa zinthu ndi sitepe yokonzekera popanda kuwonjezera chilichonse chomwe gawolo likufuna. Njira yolephera sikugwiritsa ntchito chophimba; ndikugwiritsa ntchito chimodzi mwachizolowezi pankhope pomwe palibe ntchito zake zitatu zomwe zimagwira ntchito, kapena kusiya pankhope pomwe imodzi mwa izo imagwira ntchito. Yang'anani nkhope iliyonse ya gawolo motsutsana ndi ntchito zitatu zomwe zili pamwambapa ndipo mulole zimenezo zisankhe.

Chophimba motsutsana ndi mphasa yodulidwa

Popeza zonse ziwiri ndi mphasa za ulusi wosasinthika, ziwirizi zimasokonezeka. Kusiyana kwake ndi kulemera ndi ntchito:

	Chophimba pamwamba	Mpando wodulidwa wa chingwe
Kulemera	20–90 g/m²	100–900 g/m²
Kusalala kwa ulusi	zabwino kwambiri (3.5–6 μm mu mndandanda wa Ruifiber)	ulusi wodulidwa
Udindo	ntchito ya pamwamba: kusalala, kuthandizira kwa liner, kukhazikika kwa ndondomeko	kugawa kwakukulu ndi kolimbikitsa
Udindo	nkhope yakunja, nthawi zambiri motsutsana ndi nkhungu kapena media	maziko a laminate

Chidziwitso cha mawu: ogulitsa amagwiritsa ntchito mawu akuti "chophimba pamwamba", "tishu ya pamwamba" ndi "mat yophimba pamwamba" mosasamala pa mtundu womwewo wa chinthu. Yerekezerani ndi kapangidwe ndi kulemera, osati ndi dzina.

Zogulitsa ziwirizi ndi zowonjezera, osati njira zina: choyikapo chachizolowezi cha dzimbiri chimayikapo jeli, kenako chophimba, kenakoCSMplies — chophimbacho chimapereka ntchito pamwamba pomwe CSM imapanga makulidwe ndi mphamvu.

Kusankha kulemera

Ruifiber'schophimba cha pamwambaImagwira ntchito kuyambira 20 mpaka 90 g/m², motsatizana kuti igwiritsidwe ntchito pokonza zinthu ndi manja, kupotoza ulusi ndi kupukutira. Mkati mwa unyinji umenewo, makampani amagwiritsa ntchito zolemera motere (izi ndi zofala pakati pa ogulitsa, osati pepala la deta la Ruifiber - tsimikizirani kusankha komaliza ndi ogulitsa anu):

Chingwe cholemetsa	Munthu wamba	Zimagwirizana pamene
~20 g/m²	wopepuka kwambiri, wogwirizana kwambiri	mawonekedwe ovuta kapena opindika pomwe chophimba chiyenera kutsatira mawonekedwe ake
~30 g/m²	gulu lapakati la ntchito zambiri	malo ambiri okongoletsera ndi ntchito yokhazikika ya liner; poyambira wamba
~50 g/m² ndi kupitirira apo	gawo lokhuthala lokhala ndi utomoni wambiri	nkhope zolemera za mankhwala ndi ziwalo zomwe zimafunikira chitetezo champhamvu kwambiri

Zizindikiro zitatu zimakukwezani mmwamba: mankhwala amphamvu pankhope yogwirira ntchito, kapangidwe kolimba kolimba komwe chophimba chopepuka sichingaphimbe, ndi malo athyathyathya kapena otseguka komwe kusagwirizana sikuli kofunikira. Ziwiri zimakugwetsani pansi: ma radii olimba ndi mawonekedwe a nkhungu, ndi malo okongoletsera komwe mukufuna kuti ulusi ukhale wochepa pankhope.

Chinthu chimodzi chothandiza pakugwira ntchito: zolemera zopepuka ndizosavuta. Chophimba cha 20 g/m² chimang'ambika mosavuta podula ndi kuyika kuposa chophimba cha 50 g/m², kotero nthawi zina amagula zophimba zatsopano kuti zikhale zolemera "kuti zikhale zotetezeka" kenako nkupeza kuti chophimba cholemeracho n'chovuta kuchitsatira. Ngati gulu lanu likugwira ntchito ndi zinthuzo koyamba, ndi bwino kuyitanitsa zolemera ziwiri zoyandikana nazo ndikuziyika pa bolodi loyesera musanachite oda yonse.

Kutola ndi njira: kuyika manja, kupotoza, kupukusa

Apa ndi pomwe mndandanda wazinthu zomwe wogulitsa amagulitsa umakhala wofunika kwambiri kuposa pepala la data wamba. Ruifiber imagawa chophimba chake chapamwamba m'magulu atatu kuti chigwirizane ndi njira zitatu zomwe ogula ambiri amagwiritsa ntchito:

Mndandanda	Yopangidwira	Kodi chophimbacho chikuchita chiyani pamenepo?
Kuyika manja	kukhudzana ndi mawonekedwe a nkhungu	Imagwira ntchito ngati khungu pamwamba pa gel, kusalala kapangidwe kake ndikumanga liner
Kupindika kwa filament	ziwalo zozungulira — mapaipi, matanki, zombo	zimakulungidwa ngati gawo la mzere wozungulira pamwamba pa media-faced
Kusokoneza	ma profiles opitilira	Chozungulira mawonekedwe ake chisanafe; chimachira kukhala khungu losalala lakunja lopanda ulusi wambiri wowonekera - womwe umapezeka kwambiri pa ngodya, njira, ndodo, ndi zigawo za makwerero

Chidziwitso pa njira ya polyester veil: Ruifiber imaperekanso mtundu wa polyester mu mzere wake wosokera wa veil combo; mtundu wa fiberglass umayikidwa kuti ugwiritsidwe ntchito pofuna kuletsa moto kwambiri komanso kukana kutentha kuposa mtundu wa polyester. Pa kugula chophimba chapadera pamwamba, galasi ndiye lokhazikika; funsani za polyester pokhapokha ngati pulogalamu yanu ikufunadi.

Zoyenera kutsimikizira musanayitanitse

RFQ yophimba pamwamba yomwe imapeza mtengo umodzi woyera m'malo mwa magawo atatu ofotokozera ili ndi magawo asanu:

1. Ntchito yopaka utoto— nkhope yokongoletsa, choyikapo dzimbiri, nkhope yowononga, kapena chokhazikitsa njira. Izi zimapangitsa china chilichonse kukhala chokongola.
2. Kulemera ndi m'lifupi— mwachitsanzo 30 g/m², mipukutu ya 1,000 mm. Perekani mtunda ndi chiyembekezo chololera kusiyana ndi nambala imodzi ngati muli ndi mwayi wosinthasintha.
3.Kugwirizana kwa binder ndi utomoni wanu— chomangira chiyenera kusungunuka bwino mu dongosolo lanu la utomoni (poliyesitala, vinilu ester, epoxy). Uzani wogulitsa utomoni; mupempheni kuti agwirizane ndi chomangiracho.
4. Njira— kuyika manja mmwamba, kupotoza kapena kupukusa, kuti mulandire mndandanda woyenera.
5. Kuyesa kwa chemistry yagalasi ndi kuvomereza— funsani mtundu wa galasi lomwe chophimbacho chimachokera komanso mayeso omwe akubwera omwe mungatchule (kulemera pa dera lililonse, kusungunuka kwa binder).
