"Njira yozungulira filament" ndi njira yodziwika bwino yopangira zinthu zomwe zimagwiritsidwa ntchito popanga zinthu zozungulira, monga mapaipi, matanki, ndi machubu, pogwiritsa ntchito zipangizo zophatikizika. Pachifukwa ichi, "kuzungulira fiberglass" kumatanthauza mitolo ya ulusi wosapindika wa fiberglass womwe umagwiritsidwa ntchito pozungulira filament.
Kukonzekera: Kuyenda kwa fiberglass kumakonzedwa poimasula kuchokera ku spools. Kuyendako kumatsogozedwa kudzera mu bafa ya resin, komwe imadzazidwa ndi utomoni wosankhidwa (monga epoxy, polyester, kapena vinylester).
Kupindika: Kupindika komwe kumayikidwa m'thupi kumakulungidwa pa mandrel yozungulira mwanjira yokonzedweratu. Kapangidwe ka kupindika (monga kupindika kozungulira kapena kuzungulira) ndi ngodya yopindika zimasankhidwa kutengera mawonekedwe omwe amafunidwa a chinthu chomaliza.
Kukonza: Kukonza utomoni ukatha, utomoni umafunika kukonzedwa kuti ukhale wolimba komanso wolimba. Izi zitha kuchitika kutentha kwa chipinda kapena mu uvuni, kutengera njira yogwiritsira ntchito utomoni.
Kutulutsidwa: Pambuyo pochira, kapangidwe ka bala kamachotsedwa pa mandrel, zomwe zimapangitsa kuti kapangidwe kake kakhale kozungulira komanso kopanda kanthu.
Kumaliza: Chogulitsa chomaliza chingapitirire ndi njira zina monga kudula, kuboola, kapena kupaka utoto, kutengera momwe chikugwiritsidwira ntchito.
Njira yokhotakhota ya filament pogwiritsa ntchito fiberglass roving imapereka maubwino angapo:
Mphamvu Yaikulu: Chifukwa cha ulusi wopitirira komanso kuthekera kowatsogolera mbali zomwe mukufuna, chinthu chomaliza chimakhala ndi mphamvu zambiri mbali zimenezo.
Kusintha Kosinthika: Kapangidwe kake kozungulira ndi mawonekedwe a ulusi zitha kukonzedwa kuti zikwaniritse zofunikira zinazake zamphamvu ndi kuuma.
Yotsika mtengo: Pakupanga kwakukulu, kupotoza ulusi kungakhale kotsika mtengo poyerekeza ndi njira zina zopangira zinthu zophatikizika.
Kusinthasintha: Zinthu zosiyanasiyana zokhala ndi kukula ndi mawonekedwe osiyanasiyana zimatha kupangidwa.
Kuzungulira kwa fiberglass ndikofunikira kwambiri pakupanga ulusi, zomwe zimapangitsa kuti zinthu zopangidwa ndi ulusi zikhale zolimba, zosinthasintha, komanso zotsika mtengo.
Wogwiritsa ntchito fiberglass woyendayenda mu chitoliro cha FRP
Zipangizo Zolimbikitsira: Ulusi wagalasi ndiye chinthu cholimbikitsira chomwe chimagwiritsidwa ntchito kwambiri m'mapaipi a FRP. Chimapatsa mapaipi mphamvu ndi kulimba kofunikira.
Kukana Kudzimbidwa: Poyerekeza ndi zipangizo zina zambiri, mapaipi a FRP ali ndi kukana dzimbiri kwambiri, makamaka chifukwa cha kapangidwe kake kolimba ndi ulusi wagalasi. Izi zimapangitsa mapaipi a FRP kukhala oyenera kwambiri mafakitale a mankhwala, mafuta, ndi gasi, komwe dzimbiri ndi vuto lalikulu.
Mbali Yopepuka: Mapaipi a FRP olimbikitsidwa ndi ulusi wagalasi ndi opepuka kwambiri kuposa mapaipi achitsulo kapena achitsulo achikhalidwe, zomwe zimapangitsa kuti kuyika ndi kunyamula zikhale zosavuta kwambiri.
Kukana Kuvala: Mapaipi a FRP ali ndi kukana kuvala bwino, zomwe zimapangitsa kuti akhale othandiza kwambiri ponyamula madzi okhala ndi mchenga, dothi, kapena zinthu zina zonyamulira.
Makhalidwe Oteteza Kutenthedwa: Mapaipi a FRP ali ndi makhalidwe abwino oteteza kutenthedwa, zomwe zimapangitsa kuti akhale chisankho chabwino kwambiri pamagetsi ndi kulumikizana.
Mbali Yachuma: Ngakhale mtengo woyamba wa mapaipi a FRP ukhoza kukhala wokwera kuposa zipangizo zina zachikhalidwe, nthawi yawo yayitali, kusakonza pang'ono, komanso kukonza kungapangitse kuti akhale otsika mtengo kwambiri pankhani ya ndalama zonse za moyo wawo.
Kusinthasintha kwa Kapangidwe: Mapaipi a FRP amatha kusinthidwa kuti akwaniritse zofunikira pa ntchito zinazake, kaya ndi kukula kwake, kutalika kwake, kapena makulidwe ake.
Mwachidule, kugwiritsa ntchito ulusi wagalasi m'mapaipi a FRP kumapatsa mafakitale ambiri njira yotsika mtengo, yolimba, komanso yothandiza.
Chifukwa chiyani fiberglass ikuyendayenda mu chitoliro cha FRP
Mphamvu ndi Kulimba: Kuyenda ndi fiberglass kumapatsa mapaipi a FRP mphamvu yolimba komanso yolimba, kuonetsetsa kuti mapaipiwo akusunga mawonekedwe awo komanso kapangidwe kake pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito.
Kulimbitsa Mbali: Kuzungulira kwa fiberglass kumatha kuyikidwa mbali ina kuti kupereke mphamvu yowonjezera mbali zinazake. Izi zimathandiza kuti mapaipi a FRP asinthidwe malinga ndi zosowa za ntchito inayake.
Makhalidwe Abwino Onyowetsa: Kuyenda ndi fiberglass kumakhala ndi makhalidwe abwino onyowetsa ndi ma resin, zomwe zimapangitsa kuti utomoniwo ulowetse bwino utomoniwo panthawi yopanga, zomwe zimapangitsa kuti utomoniwo ukhale wolimba kwambiri.
Kugwiritsa Ntchito Ndalama Moyenera: Poyerekeza ndi zipangizo zina zolimbikitsira, kuyendayenda kwa fiberglass ndi chisankho chotsika mtengo, chomwe chimapereka magwiridwe antchito ofunikira popanda kuwonjezera ndalama zambiri.
Kukana Kudzimbiritsa: Kudzizungulira kwa fiberglass sikudzimbiritsa, zomwe zimathandiza kuti mapaipi a FRP agwire bwino ntchito m'malo osiyanasiyana owononga.
Njira Yopangira: Kugwiritsa ntchito fiberglass roving kumathandiza kuti ntchito yopanga mapaipi a FRP ikhale yosavuta, chifukwa roving imatha kuzunguliridwa mosavuta ndi nkhungu ndikupanga utomoni pamodzi ndi utomoni.
Khalidwe Lopepuka: Kuyenda ndi fiberglass kumapereka mphamvu yofunikira pa mapaipi a FRP pomwe kumasungabe mawonekedwe opepuka, zomwe zimapangitsa kuti kuyika ndi kunyamula zikhale zosavuta.
Mwachidule, kugwiritsa ntchito fiberglass roving mu mapaipi a FRP kumachitika chifukwa cha zabwino zake zosiyanasiyana, kuphatikizapo mphamvu, kulimba, kukana dzimbiri, komanso kugwiritsa ntchito ndalama moyenera.
Njira yopitira patsogolo ya ulusi ndi yakuti gulu lachitsulo limayenda mozungulira ndi mozungulira. Njira yopitira patsogolo ya Fiberglass, kuphatikiza, kuphatikiza mchenga ndi kuyeretsa ndi zina zotero zimamalizidwa popita patsogolo pakati pa mandrel kumapeto kwa chinthucho ndipo chimadulidwa kutalika komwe chapemphedwa.
