nkhani

Ubwino ndi kuipa kwa awiriwa akufanizidwa motere:

Kuyika manja ndi njira yotseguka yomwe imatenga 65% yagalasi fiberzowonjezeredwa za polyester. Ubwino wake ndi wakuti ali ndi ufulu wambiri pakusintha mawonekedwe a nkhungu, mtengo wa nkhungu ndi wotsika, kusinthasintha kumakhala kolimba, ntchito ya mankhwala imadziwika ndi msika, ndipo ndalama zimakhala zochepa. Kotero ndizoyenera makamaka makampani ang'onoang'ono, komanso mafakitale apanyanja ndi amlengalenga, kumene nthawi zambiri amakhala gawo limodzi lalikulu. Komabe, palinso mndandanda wa mavuto mu ndondomekoyi. Ngati kutulutsa kwa volatile organic compound (VOC) kupitilira muyezo, kumakhudza kwambiri thanzi la ogwira ntchito, ndikosavuta kutaya antchito, pali zoletsa zambiri pazida zovomerezeka, magwiridwe antchito ndi otsika, ndipo utomoni umawonongeka. ndipo amagwiritsidwa ntchito mochuluka, makamaka mankhwala. Ubwino wake ndi wosakhazikika. Gawo lagalasi fiber ndi utomoni, makulidwe a zigawo, mlingo wa kupanga kwa wosanjikiza, ndi kufanana kwa wosanjikiza zonse zimakhudzidwa ndi woyendetsa, ndipo wogwiritsa ntchitoyo akuyenera kukhala ndi luso lamakono, chidziwitso ndi khalidwe.The utomoniZomwe zili muzinthu zoyika manja nthawi zambiri zimakhala pafupifupi 50% -70%. Kutulutsa kwa VOC kwa njira yotsegulira nkhungu kumadutsa 500PPm, ndipo kuphulika kwa styrene kumakhala kokwanira 35% -45% ya ndalama zomwe zimagwiritsidwa ntchito. Malamulo a mayiko osiyanasiyana ndi 50-100PPm. Pakalipano, mayiko ambiri akunja amagwiritsa ntchito cyclopentadiene (DCPD) kapena ma resins otsika a styrene, koma palibe cholowa m'malo mwa styrene ngati monoma.

Fiberglass mat ndondomeko yoyika manja

Utomoni wa vacuumnjira yoyambira ndi njira yotsika mtengo yopangira yomwe idapangidwa zaka 20 zapitazi, makamaka yoyenera kupanga zinthu zazikulu. Ubwino wake ndi motere:

(1) Chogulitsacho chimakhala ndi ntchito zabwino kwambiri komanso zokolola zambiri.Pankhani yofananagalasi la fiberglasszipangizo, mphamvu, kuuma ndi zina thupi katundu vacuum utomoni-anayambitsa zigawo zikuluzikulu akhoza bwino ndi oposa 30% -50% poyerekeza ndi manja anaika zigawo zikuluzikulu (Table 1). Pambuyo pokhazikika, zokolola zimatha kuyandikira 100%.

Table 1Kufananiza magwiridwe antchito a polyester wambagalasi la fiberglass

(2) Ubwino wa mankhwalawa ndi wokhazikika ndipo kubwereza ndikwabwino.Makhalidwe azinthu sakhudzidwa kwambiri ndi ogwira ntchito, ndipo pali kusinthasintha kwakukulu kaya ndi gawo limodzi kapena pakati pa zigawo zikuluzikulu. Ulusi wazinthu zomwe zimapangidwazo zimayikidwa mu nkhungu malinga ndi kuchuluka kwake komwe utomoni usanabayidwe, ndipo zigawozo zimakhala ndi chiŵerengero cha utomoni wokhazikika, nthawi zambiri 30% -45%, kotero kufanana ndi kubwerezabwereza kwa ntchitoyo ndi. zabwino kuposa zopangira zoyika manja. zambiri, ndi zolakwika zochepa.

(3) Ntchito yolimbana ndi kutopa imakhala bwino, yomwe ingachepetse kulemera kwa kapangidwe kake.Chifukwa cha kuchuluka kwa CHIKWANGWANI, porosity yotsika komanso magwiridwe antchito apamwamba, makamaka kuwongolera mphamvu za interlaminar, kukana kutopa kwa mankhwalawa kumakula kwambiri. Pankhani ya mphamvu zomwezo kapena zofunikira zowuma, zinthu zopangidwa ndi ndondomeko ya vacuum induction zingachepetse kulemera kwake.

(4) Wosamalira chilengedwe.Njira yolowetsera utomoni wa vacuum ndi njira yotsekeka ya nkhungu pomwe zinthu zosakhazikika komanso zowononga mpweya wapoizoni zimatsekeredwa muthumba la vacuum. Kungowona kuchuluka kwa ma volatiles kumakhalapo pomwe pampu ya vacuum imatuluka (yosefera) ndipo mbiya ya utomoni imatsegulidwa. Kutulutsa kwa VOC sikudutsa muyezo wa 5PPm. Izi zimathandiziranso kwambiri malo ogwirira ntchito kwa ogwira ntchito, kukhazikika kwa ogwira ntchito, ndikukulitsa kuchuluka kwazinthu zomwe zilipo.

(5) Umphumphu wa mankhwala ndi wabwino.Njira yoyambitsira utomoni wa vacuum imatha kupanga nthiti zolimbitsa, mapangidwe a masangweji ndi zoyika zina nthawi imodzi, zomwe zimapangitsa kukhulupirika kwa chinthucho, kotero kuti zinthu zazikuluzikulu monga ma fan hoods, ziboliboli za sitimayo ndi zida zapamwamba zitha kupangidwa.

(6) Kuchepetsa kugwiritsa ntchito zipangizo ndi ntchito.Pakuyika komweko, kuchuluka kwa utomoni kumachepetsedwa ndi 30%. Zowonongeka pang'ono, kutayika kwa utomoni kumakhala kosakwana 5%. Kuchuluka kwa ntchito, kupulumutsa 50% ya ntchito poyerekeza ndi njira yoyika manja. Makamaka pakupanga ma geometries akulu ndi ovuta a sangweji ndi zida zomangika, ndalama zomwe zimagwiritsidwa ntchito ndi ntchito ndizochulukirapo. Mwachitsanzo, popanga ziwongolero zowongoka m'makampani oyendetsa ndege, mtengo wochepetsera zomangira ndi 365 umachepetsedwa ndi 75% poyerekeza ndi njira yachikhalidwe, kulemera kwa chinthucho kumakhalabe kosasintha, ndipo magwiridwe antchito ndi abwino.

(7) Kulondola kwazinthu ndikwabwino.Kulondola kwapang'onopang'ono (kukhuthala) kwa zinthu zoyambitsira za vacuum resin ndikwabwinoko kuposa kwa zinthu zoyika manja. Pansi pakupanga komweko, makulidwe aukadaulo waukadaulo wa vacuum resin diffusion ndi 2/3 wazinthu zoyika manja. Kupatuka kwa makulidwe azinthu kumakhala pafupifupi ± 10%, pomwe njira yoyika manja nthawi zambiri imakhala ± 20%. Kusalala kwa zinthu zomwe zili pamwambazi ndikwabwino kuposa kuyika kwa manja. Khoma lamkati la chopangidwa ndi hood ya vacuum resin introduction process ndi yosalala, ndipo pamwamba pake mwachilengedwe amapanga wosanjikiza wolemera wa resin, womwe sufuna malaya owonjezera apamwamba. Kuchepetsa ntchito ndi zida zopangira mchenga ndi penti.

Zachidziwikire, njira yoyambira ya vacuum resin ilinso ndi zolakwika zina:

(1) Kukonzekera kumatenga nthawi yaitali ndipo kumakhala kovuta kwambiri.Kuyika koyenera, kuyika kwa media media, machubu opatutsa, kusindikiza kwa vacuum kogwira mtima, ndi zina zambiri. Choncho, kwa mankhwala ang'onoang'ono, nthawi ya ndondomekoyi ndi yotalikirapo kuposa ndondomeko yoyika manja.

(2) Mtengo wopangira ndi wokwera ndipo zinyalala zambiri zimapangidwira.Zida zothandizira monga filimu ya vacuum bag, diversion sing'anga, nsalu yotulutsa ndi chubu chosinthira zonse zimatha kutaya, ndipo zambiri zimatumizidwa kunja, chifukwa chake mtengo wake ndi wapamwamba kuposa njira yoyika manja. Koma chinthu chachikulu, kusiyana kwake kumakhala kochepa. Ndi kumasulira kwa zida zothandizira, kusiyana kwa mtengo uku kukucheperachepera. Kafukufuku wamakono pazinthu zothandizira zomwe zingagwiritsidwe ntchito kangapo ndi njira yachitukuko cha njirayi.

(3) Kupanga njira kumakhala ndi zoopsa zina.Makamaka pazinthu zazikulu komanso zovuta zamapangidwe, kulowetsedwa kwa utomoni kukalephera, mankhwalawa ndi osavuta kuchotsedwa.

Choncho, kufufuza koyambirira kwabwino, kuwongolera kokhazikika kwa ndondomeko ndi njira zothetsera vutoli ndizofunikira kuti zitsimikizidwe kuti ntchitoyi ikuyenda bwino.
