Kodi glass fiber reinforced plastic ndi chiyani?
Mapulasitiki opangidwa ndi fiber fiber ndi mitundu yosiyanasiyana yazinthu zophatikizika zomwe zimakhala ndi zinthu zosiyanasiyana komanso ntchito zambiri.Ndizinthu zatsopano zogwirira ntchito zopangidwa ndi utomoni wopangira ndifiberglass kompositi zinthu kudzera munjira yophatikizika.
Makhalidwe a mapulasitiki opangidwa ndi galasi fiber:
(1）Kukana bwino kwa dzimbiri: FRP ndi chinthu chabwino chosachita dzimbiri.Ili ndi kukana bwino kwa mlengalenga;madzi ndi ambiri woipa wa asidi ndi zamchere;mchere, mafuta osiyanasiyana ndi zosungunulira, ndipo wakhala ankagwiritsa ntchito mankhwala odana ndi dzimbiri.mbali zonse.Akulowa m'malo mwa chitsulo cha carbon;chitsulo chosapanga dzimbiri;matabwa;zitsulo zopanda chitsulo ndi zipangizo zina.
(2) Kulemera kopepuka ndi mphamvu yayikulu: Kachulukidwe wachibale wa FRP uli pakati pa 1.5 ndi 2.0, womwe ndi 1/4 mpaka 1/5 wa chitsulo cha kaboni, koma mphamvu yamakomedwe ili pafupi kapena kuposa kuposa ya kaboni. chitsulo, ndi mphamvu tingayerekeze ndi apamwamba kalasi aloyi zitsulo., amagwiritsidwa ntchito kwambiri muzamlengalenga;zotengera zothamanga kwambiri ndi zinthu zina zomwe zimafunikira kuchepetsa kulemera kwawo.
(3) Mphamvu zabwino zamagetsi: FRP ndi chinthu chabwino kwambiri chotchingira, chomwe chimagwiritsidwa ntchito popanga zotchingira, ndipo chimatha kukhalabe ndi magwiridwe antchito abwino pama frequency apamwamba.
(4) Kuchita bwino kwamafuta: FRP ili ndi mphamvu zochepa zamagetsi, 1.25 ~ 1.67KJ kutentha kwapakati, 1/100 ~ 1/1000 yokha yachitsulo ndi chinthu chabwino kwambiri chotetezera kutentha.Oyenera kuteteza kutentha ndi kukana kwa ablation pansi pazikhalidwe zotentha kwambiri.
(5) Kuchita bwino kwa ndondomekoyi: ndondomeko yowumba imatha kusankhidwa molingana ndi mawonekedwe a mankhwala, ndipo ndondomekoyi ndi yosavuta ndipo ikhoza kupangidwa nthawi imodzi.
(6) Mapangidwe abwino: zida zitha kusankhidwa mokwanira malinga ndi zosowa kuti zikwaniritse zofunikira zantchito ndi kapangidwe kazinthu.
(7) Low elastic modulus: The elastic modulus ya FRP ndi 2 nthawi zazikulu kuposa zamatabwa koma 10 nthawi yaying'ono kuposa yachitsulo, choncho nthawi zambiri amamva kuti kulimba sikukwanira mu kapangidwe ka mankhwala ndipo kumakhala kosavuta.Njira yothetsera vutoli ikhoza kupangidwa kukhala chipolopolo chopyapyala;kamangidwe ka masangweji amathanso kupangidwa mwa mawonekedwe a ulusi wokwera wa modulus kapena nthiti zolimbitsa.
(8) Kusasunthika kwa kutentha kwa nthawi yayitali: Nthawi zambiri, FRP singagwiritsidwe ntchito kwa nthawi yaitali pa kutentha kwakukulu, ndipo mphamvu ya FRP ya polyester resin-purpose resin idzachepa kwambiri ikakhala pamwamba pa madigiri 50.
(9) Kukalamba chodabwitsa: pansi pa zochita za cheza ultraviolet;mphepo, mchenga, mvula ndi matalala;media media;kupsinjika kwamakina, etc., ndikosavuta kuyambitsa kuwonongeka kwa magwiridwe antchito.
(10) Mphamvu yakumeta ubweya wa interlaminar: Mphamvu yometa ubweya wa interlaminar imatengedwa ndi utomoni, motero imakhala yotsika.Kumata kwa interlayer kumatha kusinthidwa posankha njira, pogwiritsa ntchito cholumikizira, ndi zina zambiri, ndikuyesera kupewa kumeta ubweya wamkati panthawi yopanga mankhwala.
Ubwino wa mapulasitiki olimbitsa magalasi:
Kutentha kosamva kutentha kwa mapulasitiki olimbikitsidwa ndi fiber fiber ndi apamwamba kwambiri kuposa opanda ulusi wagalasi, makamaka mapulasitiki a nayiloni.
Mapulasitiki opangidwa ndi zitsulo zamagalasi amakhala ndi kuchepa kochepa komanso kulimba kwambiri.
The galasi CHIKWANGWANI analimbitsa pulasitiki si nkhawa mng'alu, ndi kukana zotsatira zafemoglas fibra de vidrio pulasitiki ndi yabwino kwambiri
Mphamvu ya mapulasitiki opangidwa ndi magalasi opangidwa ndi fiber ndi apamwamba, monga: mphamvu yokhazikika, mphamvu yopondereza, mphamvu yopindika, zonse ndizokwera kwambiri.
Chifukwa chowonjezera zowonjezera zina,mchere wa fibermapulasitiki olimbikitsidwa achepetsa kwambiri kuyaka kwa mapulasitiki olimba agalasi, ndipo zida zambiri sizingayatsidwe, chifukwa chake ndizinthu zoletsa moto.
Kuipa kwa mapulasitiki opangidwa ndi galasi fiber:
Chifukwa chowonjezera chandi glassfiber, pulasitiki yolimba yagalasi yakhala yosaoneka bwino, ndipo imaonekera musanawonjezere ulusi wagalasi.
Pulasitiki yolimbitsa magalasi apulasitiki imakhala yolimba komanso yowonjezereka kuposa pulasitiki yopanda galasi;
Chifukwa cha kuwonjezeredwa kwa galasi la galasi, kusungunuka kwa kusungunuka kwa zipangizo zonse kumawonjezeka, madzi amadzimadzi amakhala osauka, ndipo mphamvu ya jekeseni imakhala yochuluka kwambiri kuposa yopanda galasi.Pakuumba kwa jakisoni wamba, kutentha kwa jakisoni kwa mapulasitiki onse olimbikitsidwa kumakhala kopitilira apo osawonjezera ulusi wagalasi.Ulusi wagalasi udakwezedwa kale ndi 10 ℃-30 ℃.
Chifukwa cha kuwonjezera kwa galasi CHIKWANGWANI ndi zina, hygroscopic katundu wadaw fiberglass mapulasitiki olimbikitsidwa amawonjezedwa kwambiri.Mapulasitiki apachiyambi omwe samamwa madzi nawonso amatha kuyamwa.Choncho, ayenera zouma pa jekeseni akamaumba.
Pa jekeseni akamaumba ndondomeko ya galasi CHIKWANGWANI analimbitsa pulasitiki, galasi CHIKWANGWANI angalowe padziko mankhwala pulasitiki, kupanga pamwamba pa mankhwala kwambiri akhakula ndi zamaanga.Kuti akwaniritse mawonekedwe apamwamba, makina otenthetsera nkhungu amagwiritsidwa ntchito kutenthetsa nkhungu panthawi yopangira jekeseni, kuti polima pulasitiki ilowe pamwamba pa mankhwala, koma mawonekedwe a pulasitiki oyera sangathe kukwaniritsidwa.
Pambuyo kulimbikitsa ulusi wagalasi,ndi glass fiberglass ndi chinthu chokhala ndi kuuma kwakukulu.Chowonjezeracho chikatenthedwa pa kutentha kwakukulu, ndi mpweya wowononga kwambiri, womwe umapangitsa kuti pakhale kuwonongeka kwakukulu ndi kuwonongeka kwa screw ndi jekeseni wa makina opangira jekeseni.Choncho, zinthu zamtunduwu zimagwiritsidwa ntchito popanga.Mukamagwiritsa ntchito makina opangira jekeseni ndi jekeseni, samalani ndi mankhwala odana ndi dzimbiri komanso kuuma kwapamwamba kwa zida.
Kulimbikitsa mphamvu ya galasi ulusi pa nayiloni
Nylon, yomwe imadziwikanso kuti polyamide, ndi chinthu chopangidwa ndi zinthu zambiri, chomwe chimagwiritsidwa ntchito munsalu, kulongedza, mbali zamakina ndi magawo ena.
Monga pulasitiki yauinjiniya, PA66 ili ndi magulu ambiri a hydrophilic amide, omwe amalepheretsa ntchito yake.Amagwiritsidwa ntchito kwambiri m'makampani kuti asinthe pogwiritsa ntchito copolymerization, kuphatikiza kulimba, komanso kulimbikitsa.
Glass fiber reinforcement ndi njira yomwe imagwiritsidwa ntchito kwambiri.Itha kupititsa patsogolo kukana, mphamvu, kuuma komanso kukhazikika kwa nayiloni.
Ulusi wagalasi umapangidwa ndi pyrophyllite, mchenga wa quartz, miyala yamchere ndi mchere wina kudzera pamoto wotentha kwambiri, kujambula waya, mafunde, kuluka ndi njira zina, ndipo m'mimba mwake monofilament ndi pafupifupi ma microns ochepa.
Mfundo yolimbitsa magalasi: Pali njira zitatu zopangira mphamvu ya utomoni: kusweka kwa ulusi, kutulutsa utomoni, ndi kusweka kwa utomoni.Pamene utali wa ulusi ukuwonjezeka, ulusi wokoka umadya mphamvu zambiri, zomwe zimapindulitsa pakusintha kwamphamvu kwamphamvu.
PA66 / galasi CHIKWANGWANI gulu zinthu ndi otsika mayamwidwe madzi, mkulu enieni mphamvu ndi kukana mankhwala, ndipo mankhwala ake ndi zabwino mayamwidwe kukana chinyezi, kukhazikika dimensional, mphamvu mkulu, kuuma, ndi ntchito processing, choncho chimagwiritsidwa ntchito mu njanji, makina, magalimoto. , zida zamagetsi ndi magawo ena.
Kutalika kwazinthu zotanuka modulus CHIKWANGWANI galasiNthawi zambiri amagwiritsidwa ntchito kulimbitsa nayiloni ndi pafupifupi 3mm mpaka 12mm.Pamene utali wa fiber ukuchulukirachulukira, zotsatira zake pakulimbitsa zinthu zimawonjezeka.Ndibwino kuti mufike 12 mm.
Nthawi zambiri, kutalika kwafiberglass filamentndi 12mm, ndi kutalika kwakeakanadulidwa galasi CHIKWANGWANIndi 3mm.Poyerekeza ndi ulusi wamagalasi afupiafupi, chochititsa chidwi cha kulimbitsa magalasi aatali ndikuti mphamvu yake imachulukitsidwa kawiri.Kuphatikiza apo, magalasi aatali opangidwa ndi nayiloni opangidwa ndi zida za nayiloni ali ndi zabwino zamphamvu kwambiri, kukhazikika kwakukulu, kulimba kwamphamvu kwambiri, kukana kutentha kwakanthawi kochepa komanso kukana kutopa bwino, ndipo amatha kukhalabe ndi zida zamakina abwino pakutentha kwambiri komanso kutentha kwambiri., yomwe ingagwiritsidwe ntchito ngati zomangira m'malo mwachitsulo.
