Ubwino ndi kuipa kwa ziwirizi zikuyerekezeredwa motere:

Kuyika manja mmwamba ndi njira yotseguka yomwe pakadali pano imayimira 65% yaulusi wagalasiZopangidwa ndi polyester zolimbikitsidwa. Ubwino wake ndi wakuti uli ndi ufulu waukulu pakusintha mawonekedwe a nkhungu, mtengo wa nkhungu ndi wotsika, kusinthasintha kwake ndi kwamphamvu, magwiridwe antchito a chinthucho amadziwika ndi msika, ndipo ndalama zomwe zimayikidwa ndizochepa. Chifukwa chake ndi yoyenera makamaka makampani ang'onoang'ono, komanso mafakitale am'madzi ndi ndege, komwe nthawi zambiri kumakhala gawo lalikulu kamodzi kokha. Komabe, palinso mavuto angapo munjira iyi. Ngati kutulutsa kwa volatile organic compound (VOC) kupitirira muyezo, kumakhudza kwambiri thanzi la ogwira ntchito, n'zosavuta kutaya antchito, pali zoletsa zambiri pazinthu zololedwa, magwiridwe antchito a chinthucho ndi otsika, ndipo utomoni umawonongeka ndikugwiritsidwa ntchito mochuluka, makamaka chinthucho. Ubwino wake ndi wosakhazikika. Chiŵerengero chaulusi wagalasi ndi utomoni, makulidwe a ziwalo, kuchuluka kwa kapangidwe ka gawo, ndi kufanana kwa gawo lonselo zonse zimakhudzidwa ndi wogwiritsa ntchito, ndipo wogwiritsa ntchitoyo amafunika kukhala ndi ukadaulo wabwino, chidziwitso, ndi khalidwe labwino.UtomoniZomwe zili muzinthu zoyikidwa ndi manja nthawi zambiri zimakhala pafupifupi 50%-70%. Kutulutsa kwa VOC kwa njira yotsegulira nkhungu kumaposa 500PPm, ndipo kusinthasintha kwa styrene kumakhala kokwera kufika pa 35%-45% ya kuchuluka komwe kwagwiritsidwa ntchito. Malamulo a mayiko osiyanasiyana ndi 50-100PPm. Pakadali pano, mayiko ambiri akunja amagwiritsa ntchito cyclopentadiene (DCPD) kapena ma resins ena otsika a styrene, koma palibe cholowa m'malo mwa styrene ngati monomer.

Mpando wagalasi njira yokonzekera ndi manja

Utomoni wa vacuumNjira yoyambira ndi njira yopangira yotsika mtengo yomwe idapangidwa m'zaka 20 zapitazi, makamaka yoyenera kupanga zinthu zazikulu. Ubwino wake ndi uwu:

(1) Chogulitsachi chili ndi magwiridwe antchito abwino kwambiri komanso zokolola zambiri.Pankhani yomweyifiberglassZipangizo zopangira, mphamvu, kuuma ndi zinthu zina zakuthupi za zinthu zomwe zimapangidwa ndi utomoni wa vacuum zitha kukwezedwa ndi zoposa 30%-50% poyerekeza ndi zinthu zomwe zimagwiritsidwa ntchito ndi manja (Table 1). Pambuyo poti njira yokhazikika, phindu likhoza kukhala pafupi ndi 100%.

Gome 1Kuyerekeza magwiridwe antchito a polyester wambafiberglass

(2) Ubwino wa chinthucho ndi wokhazikika ndipo chingathe kubwerezedwanso bwino.Ubwino wa chinthucho sukhudzidwa kwambiri ndi ogwiritsa ntchito, ndipo pali kusinthasintha kwakukulu kaya ndi chinthu chomwecho kapena pakati pa zigawo. Kuchuluka kwa ulusi wa chinthucho kwayikidwa mu nkhungu malinga ndi kuchuluka komwe kwatchulidwa utomoni usanalowetsedwe, ndipo zigawozo zimakhala ndi chiŵerengero chofanana cha utomoni, nthawi zambiri 30%-45%, kotero kufanana ndi kubwerezabwereza kwa magwiridwe antchito a chinthucho ndikwabwino kuposa zinthu zomwe zimagwiritsidwa ntchito ndi manja, ndipo zolakwika zochepa.

(3) Kugwira ntchito bwino kwa thupi kumachepa, zomwe zingathandize kuchepetsa kulemera kwa kapangidwe kake.Chifukwa cha kuchuluka kwa ulusi, kuchepa kwa ma porosity komanso magwiridwe antchito apamwamba azinthu, makamaka kukwera kwa mphamvu ya interlaminar, kukana kutopa kwazinthuzo kumawonjezeka kwambiri. Pankhani ya mphamvu zomwezo kapena kuuma, zinthu zopangidwa ndi njira yopangira vacuum zimatha kuchepetsa kulemera kwa kapangidwe kake.

(4) Yosamalira chilengedwe.Njira yothira utomoni wa vacuum ndi njira yotsekedwa ya nkhungu pomwe zinthu zachilengedwe zosasunthika komanso zoipitsa mpweya wapoizoni zimayikidwa mu thumba la vacuum. Zinthu zochepa zokha zomwe zimasinthasintha zimakhalapo pamene pampu ya vacuum imatuluka mpweya (yosefedwa) ndipo mbiya ya utomoni imatsegulidwa. Utsi wa VOC supitirira muyezo wa 5PPm. Izi zimathandizanso kwambiri malo ogwirira ntchito kwa ogwira ntchito, zimakhazikika pantchito, komanso zimakulitsa mitundu yosiyanasiyana ya zipangizo zomwe zilipo.

(5) Ubwino wa zinthu ndi wabwino.Njira yoyambitsira utomoni wa vacuum ikhoza kupanga nthiti zolimbitsa, mapangidwe a masangweji ndi zinthu zina nthawi imodzi, zomwe zimapangitsa kuti zinthuzo zikhale bwino, kotero zinthu zazikulu monga ma fan hood, ma ship hulls ndi superstructures zitha kupangidwa.

(6) Chepetsani kugwiritsa ntchito zipangizo zopangira ndi ntchito.Mu kuyika komweko, kuchuluka kwa utomoni kumachepetsedwa ndi 30%. Zinyalala zochepa, kutayika kwa utomoni kumakhala kochepera 5%. Kugwira ntchito molimbika, kupulumutsa antchito opitilira 50% poyerekeza ndi njira yoyika ndi manja. Makamaka pakuumba ma geometries akuluakulu komanso ovuta a sandwich ndi zida zomangira zolimba, ndalama zomwe zimagwiritsidwa ntchito komanso zosungira antchito zimakhala zazikulu kwambiri. Mwachitsanzo, popanga ma rudders oyima mumakampani opanga ndege, mtengo wochepetsera zomangira ndi 365 umachepetsedwa ndi 75% poyerekeza ndi njira yachikhalidwe, kulemera kwa chinthucho sikunasinthe, ndipo magwiridwe antchito amakhala abwinoko.

(7) Kulondola kwa chinthucho ndi kwabwino.Kulondola kwa kukula kwa zinthu zoyambitsa utomoni wa vacuum kuli bwino kuposa zinthu zokhazikitsa ndi manja. Pansi pa kuyika komweko, makulidwe a zinthu zoyambitsa utomoni wa vacuum ndi 2/3 ya zinthu zokhazikitsa ndi manja. Kupatuka kwa makulidwe a zinthu ndi pafupifupi ± 10%, pomwe njira yokhazikitsa ndi manja nthawi zambiri ndi ± 20%. Kusalala kwa pamwamba pa chinthucho kuli bwino kuposa zinthu zokhazikitsa ndi manja. Khoma lamkati la chinthu chopangira utomoni wa vacuum ndi losalala, ndipo pamwamba pake pamapanga utomoni wochuluka, womwe sufuna utoto wowonjezera. Kuchepa kwa ntchito ndi zipangizo zokonzera ndi kupaka utoto.

Zachidziwikire, njira yoyambira ya vacuum resin yomwe ilipo pano ilinso ndi zofooka zina:

(1) Kukonzekera kumatenga nthawi yayitali ndipo kumakhala kovuta kwambiri.Kuyika bwino zinthu, kuyika zida zosinthira, machubu osinthira, kutseka bwino zinthu zotayira mpweya, ndi zina zotero ndikofunikira. Chifukwa chake, pazinthu zazing'ono, nthawi yokonza zinthu ndi yayitali kuposa njira yoyikamo zinthu ndi manja.

(2) Mtengo wopangira ndi wokwera ndipo zinyalala zambiri zimapangidwa.Zipangizo zothandizira monga filimu ya vacuum bag, diversion medium, release cloth ndi diversion tube zonse ndi zotayidwa, ndipo zambiri mwa izo zimatumizidwa kunja, kotero mtengo wopangira ndi wokwera kuposa njira yokonzera ndi manja. Koma kukula kwa chinthucho, kusiyana kwake kumakhala kochepa. Ndi malo a zipangizo zothandizira, kusiyana kwa mtengo kumeneku kukuchepa kwambiri. Kafukufuku waposachedwa wa zipangizo zothandizira zomwe zingagwiritsidwe ntchito kangapo ndi njira yopititsira patsogolo njirayi.

(3) Kupanga njira kuli ndi zoopsa zina.Makamaka pazinthu zazikulu komanso zovuta kupanga, pamene kulowetsedwa kwa utomoni sikulephera, chinthucho chimakhala chosavuta kutaya.

Choncho, kafukufuku woyambirira wabwino, kuwongolera njira mosamala komanso njira zothanirana ndi vutoli ndizofunikira kuti zitsimikizire kuti njirazi zikuyenda bwino.
