Kugwiritsa ntchito mphamvu ya ulusi wagalasi mu ulimi

Kwa zaka zambiri, kulimbitsa zitsulo kwakhala chinthu chofunikira kwambiri pa ntchito yomanga. Komabe, zambiri zenizeni za uinjiniya zikusonyeza kuti ngati kapangidwe ka konkriti kolimba sikapangidwa bwino kapena malo omwe ali pamalopo ndi ovuta, kulimba ndi magwiridwe antchito a kulimbitsa zitsulo kudzakhudzidwa. Akatswiri ambiri aku China ndi akunja atsimikiza kuti kugwiritsa ntchitocholimbitsa chagalasi cha fiber chophatikizikaKubwezeretsa zitsulo m'malo mwa zitsulo m'magawo enaake ndi njira yothandiza yothetsera vutoli. Kulimbitsa zitsulo pogwiritsa ntchito fiber yagalasi ndi mtundu watsopano wa zinthu zopangidwa ndi pultrusion ndi mankhwala apadera pamwamba, pogwiritsa ntchito ulusi wagalasi ngati zolimbitsa, epoxy resin ngati zinthu zopangira matrix, komanso kuphatikiza zinthu zothandizira zoyenera (monga ma monomers olumikizirana, oyambitsa, othamangitsa, othandizira kusintha, oletsa moto, zoletsa polymerization, zodzaza, utoto, ndi zina zotero).

1. Makhalidwe a Kulimbitsa kwa Ulusi wa Galasi

(1) Mphamvu Yolimba Kwambiri: Mphamvu yolimba ya kulimbitsa ulusi wagalasi ndi yapamwamba kuposa mphamvu yachitsulo wamba, yoposa mphamvu ya kulimbitsa chitsulo chamtundu womwewo ndi 20%, komanso imakhala ndi kukana kutopa kwabwino.

(2) Yopepuka: Kulemera kwa kulimbitsa ulusi wagalasi ndi gawo limodzi mwa magawo anayi okha a kulimbitsa kwachitsulo komweko, ndi kuchulukana pakati pa 1.5 ndi 1.9 (g/cm3). (3) Kulimbana ndi dzimbiri mwamphamvu: Kulimbana ndi dzimbiri kuchokera ku ma acid, alkali, ndi mankhwala ena; kumalimbana ndi kukokoloka kwa ma ayoni a chloride ndi pH yochepa, makamaka kukana kwambiri kwa mankhwala a carbon ndi mankhwala a chlorine.

(3) Kugwirizana kwamphamvu kwa zinthu: Kuchuluka kwa kutentha kwa konkriti yolimbikitsidwa ndi ulusi wagalasi kumakhala kofanana ndi kwa simenti kuposa kwa chitsulo, zomwe zimapangitsa kuti konkriti yolimbikitsidwa ndi ulusi wagalasi ikhale yogwirizana kwambiri ndi konkriti.

(4) Kusinthasintha kwakukulu kwa kapangidwe: Konkire yolimbikitsidwa ndi ulusi wagalasi ili ndi modulus yokhazikika komanso miyeso yokhazikika pansi pa kutentha. Ikhoza kupindika ndikupangidwa kukhala mawonekedwe aliwonse, ili ndi magwiridwe antchito abwino otetezeka, siigwira ntchito yoyendetsa magetsi, siigwiritsa ntchito magetsi, siigwira moto, komanso siigwira ntchito mosasunthika. Ndi kusintha kwa njira, sipanga ma spark ikagundana ndi zitsulo.

(6) Kulowa kwamphamvu kwa maginito: Konkire yolimbikitsidwa ndi ulusi wagalasi ndi chinthu chopanda maginito, zomwe zimapangitsa kuti pasakhale kufunikira kwa njira yochotsera maginito mu konkire yopanda maginito kapena yamagetsi.

(7) Kapangidwe koyenera: Konkire yolimbikitsidwa ndi ulusi wagalasi ikhoza kupangidwa m'zigawo zosiyanasiyana zokhazikika komanso zosakhazikika zokhala ndi magawo osiyanasiyana komanso kutalika kosiyanasiyana malinga ndi zofunikira za ogwiritsa ntchito. Kumangirira pamalopo kungachitike pogwiritsa ntchito zingwe zomangira zosagwiritsa ntchito chitsulo, zomwe zimapangitsa kuti ntchitoyo ikhale yosavuta.

Kulimbitsa kwa fiberglass composite kumalimbana ndi dzimbiri kwambiri, makamaka chifukwa kumapirira kwambiri njira za pH ndi zinthu zowononga. Kaya m'malo omwe ali ndi mvula kapena m'malo omwe ali ndi chinyezi, kulimbitsa kwa fiberglass composite kumalimbana ndi dzimbiri bwino muulimi ndipo nthawi zambiri kumakhala ndi nthawi yayitali kuposa kulimbitsa kwachitsulo chachikhalidwe.

2. Kugwiritsa Ntchito Fiberglass Composite Reinforcement mu Ulimi

(1) Mipanda yolimbana ndi kuba yakhala ikugwiritsidwa ntchito kwambiri paulimi kwa nthawi yayitali. Mipanda yachikhalidwe imagwiritsa ntchito zolimbitsa zitsulo ngati ndodo zothandizira, koma kugwiritsidwa ntchito panja kwa nthawi yayitali kumabweretsa dzimbiri ndi kulephera kwa zolimbitsa zitsulo. Kukana kwamphamvu kwa fiberglass composite resistance kumapangitsa kuti ikhale yoyenera kwambiri m'malo mwa zolimbitsa zitsulo ngati ndodo zothandizira.

(2) Kupereka chithandizo pa mitengo ikakula n'kofunika kwambiri. Ndodo zothandizira zachikhalidwe zimapangidwa makamaka ndi matabwa ndi chitsulo, koma dzimbiri ndi ukalamba zimachitika zikagwiritsidwa ntchito kwa nthawi yayitali, zomwe zimapangitsa kuti ndodo zothandizira zisagwire ntchito bwino nyengo ikavuta.Kulimbitsa kwa fiberglass compositeSikuti ndi yopepuka komanso yolimba kwambiri komanso imateteza dzimbiri bwino, zomwe zimapangitsa kuti ikhale chinthu choyenera kwambiri m'malo mwa ndodo zothandizira zamatabwa ndi zitsulo.

(3) Mafelemu othandizira nyumba zosungiramo zomera zaulimi nthawi zambiri amapangidwa ndi matabwa ndi chitsulo. Chifukwa cha kutentha kwambiri ndi chinyezi cha chilengedwe, mafelemu othandizira opangidwa ndi matabwa ndi chitsulo amakalamba ndi kuzizira, zomwe zimaika pangozi chitetezo. Kulimbitsa kwa fiberglass kungapangidwe ndikupanga mafelemu othandizira amitundu yosiyanasiyana ndi zofunikira malinga ndi zofunikira pakugwiritsa ntchito. Kutha kuyikidwa mwachindunji pamalopo, ndi kopepuka, komanso kosavuta kumanga; chinthucho chokha sichimalimbana ndi dzimbiri komanso sichikalamba. Poganizira chitetezo komanso ndalama zochepa, kulimbitsa kwa fiberglass composite ndikofunikira kwambiri ngati kapangidwe kothandizira kutentha.

(4) Pakukula kwa zipatso ndi ndiwo zamasamba, mafelemu othandizira ndi ofunikira kuti akule bwino. Mafelemu othandizira achikhalidwe amapangidwa makamaka ndi matabwa ndi chitsulo, koma chifukwa cha mphamvu zawo zochepa, amatha kukalamba ndi dzimbiri m'malo ozizira. Zipatso ndi ndiwo zamasamba zikakhwima ndikufika kulemera kwina, mafelemu othandizira amatha kugwa. Fiberglass composite reinforcement ili ndi mawonekedwe opepuka, olimba kwambiri, komanso osadzimbidwa, zomwe zimapangitsa kuti ikhale yoyenera kwambiri kusintha matabwa ndi chitsulo ngati mafelemu othandizira zipatso ndi ndiwo zamasamba.

3. MapetoChopangidwa ndi magalasi a fiberglassKulimbitsa kumaphatikiza mphamvu zabwino kwambiri zamakina, zakuthupi, komanso zamakemikolo za epoxy resin ndi fiberglass, ndipo zimagwiritsidwa ntchito kwambiri kuthetsa vuto la dzimbiri la chitsulo m'malo apadera ogwiritsidwa ntchito. Kutsika mtengo kwake, kapangidwe kake kosavuta, komanso kukana dzimbiri kwapangitsa kuti pang'onopang'ono ilowe m'malo mwa chitsulo ndikukhala ndi malo m'munda waulimi, zomwe zimagwira ntchito yofunika kwambiri pakukula kwa chuma cha dziko.
