1. Waya wachitsulo
Pofuna kuonetsetsa kuti chingwecho chingathe kupirira kugwedezeka kokwanira kwa axial pakuyika ndi kugwiritsa ntchito, chingwecho chiyenera kukhala ndi zinthu zomwe zingathe kunyamula katundu, zitsulo, zopanda zitsulo, pogwiritsa ntchito waya wachitsulo wapamwamba kwambiri ngati gawo lolimbikitsa, kotero kuti chingwechi chimakhala ndi kukana kupanikizika kwambiri, kukana mphamvu, waya wachitsulo amagwiritsidwanso ntchito pa chingwe pakati pa sheath yamkati ndi mchimake wakunja wa zida. Malinga ndi okhutira mpweya akhoza kugawidwa mu mkulu mpweya zitsulo waya ndi otsika mpweya zitsulo waya.
(1) Waya wachitsulo wapamwamba wa carbon
Mkulu mpweya zitsulo waya zitsulo ayenera kukwaniritsa zofunika luso la GB699 apamwamba mpweya zitsulo, zili sulfure ndi phosphorous ndi za 0,03%, malinga ndi zosiyanasiyana padziko mankhwala akhoza kugawidwa mu kanasonkhezereka zitsulo waya ndi phosphating zitsulo waya. Waya wazitsulo wazitsulo umafuna kuti nthaka isanjike ikhale yofanana, yosalala, yokhazikika, pamwamba pa waya wachitsulo ayenera kukhala woyera, wopanda mafuta, madzi, opanda banga; Phosphating wosanjikiza wa waya phosphating ayenera kukhala yunifolomu ndi yowala, ndipo pamwamba pa waya ayenera kukhala opanda mafuta, madzi, dzimbiri mawanga ndi mikwingwirima. Chifukwa kuchuluka kwa kusinthika kwa haidrojeni ndikochepa, kugwiritsa ntchito waya wachitsulo wa phosphating ndikofala kwambiri tsopano.
(2) Waya wachitsulo wochepa wa carbon
Low mpweya zitsulo waya zambiri ntchito zida zida chingwe, pamwamba pa waya zitsulo ayenera yokutidwa ndi yunifolomu ndi mosalekeza nthaka wosanjikiza, nthaka wosanjikiza sayenera ming`alu, zolembera, pambuyo mapiringidzo mayeso, pasakhale anabala zala akhoza kufufuta. kukhumudwa, kukhumudwa ndi kukhumudwa.
2. Chingwe chachitsulo
Ndi chitukuko cha chingwe ku chiwerengero chachikulu chapachimake, kulemera kwa chingwe kumawonjezeka, ndipo kupanikizika komwe kulimbikitsidwa kumafunikanso kumawonjezeka. Pofuna kupititsa patsogolo mphamvu ya chingwe cha kuwala kuti athe kunyamula katundu ndi kukana kupsinjika kwa axial komwe kungapangidwe mu kuika ndi kugwiritsa ntchito chingwe cha kuwala, chingwe chachitsulo monga gawo lolimbikitsa la chingwe cha kuwala ndiloyenera kwambiri, ndipo ali ndi kusinthasintha kwina. Chingwe chachitsulo chimapangidwa ndi zingwe zingapo zachitsulo chopotoka, malinga ndi kapangidwe kagawo kangagawike mu 1 × 3,1 × 7,1 × 19 mitundu itatu. Kulimbitsa chingwe nthawi zambiri kumagwiritsa ntchito chingwe chachitsulo cha 1 × 7, chingwe chachitsulo molingana ndi mphamvu yokhazikika imagawidwa mu: 175, 1270, 1370, 1470 ndi 1570MPa magiredi asanu, zotanuka modulus ya chingwe chachitsulo ziyenera kukhala zazikulu kuposa 180GPa. Chitsulo chomwe chimagwiritsidwa ntchito ngati chingwe chachitsulo chiyenera kukwaniritsa zofunikira za GB699 "Technical Conditions for high quality carbon steel structure", ndipo pamwamba pa waya wazitsulo zomwe zimagwiritsidwa ntchito popanga zitsulo ziyenera kukhala zokutidwa ndi yunifolomu ndi wosanjikiza wa zinki, ndipo pamenepo. sayenera mawanga, ming'alu ndi malo opanda zinki plating. M'mimba mwake ndi mtunda wa waya wa strand ndi yunifolomu, ndipo sayenera kukhala yotayirira pambuyo podulidwa, ndipo waya wachitsulo wa waya wa strand ayenera kugwirizanitsidwa kwambiri, popanda crisscross, fracture ndi kupindika.
3.Mtengo wa FRP
FRP ndiye chidule cha chilembo choyamba cha pulasitiki yolimba yachingerezi, yomwe ndi zinthu zopanda zitsulo zosalala komanso zowoneka bwino zakunja zomwe zimapezedwa pokutira pamwamba pa zingwe zingapo za utomoni wagalasi ndi utomoni wochiritsa, ndipo imasewera kulimbikitsa. udindo mu chingwe cha kuwala. Popeza FRP ndi zinthu zopanda zitsulo, ili ndi ubwino wotsatirawu poyerekeza ndi kulimbitsa zitsulo: (1) Zida zopanda zitsulo sizimakhudzidwa ndi magetsi, ndipo chingwe cha kuwala ndi choyenera kumadera a mphezi; (2) FRP sipanga ma electrochemical reaction ndi chinyezi, sichitulutsa mpweya woyipa ndi zinthu zina, ndipo ndi yoyenera kumadera amvula, otentha komanso amvula; (3) sichimapanga kulowetsedwa kwamakono, ikhoza kukhazikitsidwa pamzere wapamwamba wamagetsi; (4) FRP ili ndi mawonekedwe a kulemera kopepuka, komwe kumatha kuchepetsa kwambiri kulemera kwa chingwe. FRP pamwamba iyenera kukhala yosalala, yosakhala yozungulira iyenera kukhala yaying'ono, m'mimba mwake iyenera kukhala yofanana, ndipo pasakhale mgwirizano muutali wamba wa disc.
4. Aramidi
Aramid (polyp-benzoyl amide fiber) ndi mtundu wa ulusi wapadera wokhala ndi mphamvu zambiri komanso modulus wapamwamba. Amapangidwa kuchokera ku p-aminobenzoic acid monga monomer, pamaso pa chothandizira, mu dongosolo la NMP-LiCl, ndi yankho la condensation polymerization, ndiyeno ndi kupota konyowa ndi chithandizo cha kutentha kwakukulu. Pakali pano, mankhwala ntchito makamaka mankhwala chitsanzo KEVLAR49 opangidwa ndi DuPont mu United States ndi mankhwala chitsanzo Twaron opangidwa ndi Akzonobel ku Netherlands. Chifukwa cha kukana kwambiri kutentha kwapamwamba komanso kukana kwa okosijeni wamafuta, amagwiritsidwa ntchito popanga zida zonse zodziyimira pawokha (ADSS) zowonjezera chingwe chowonjezera.
5. Ulusi wagalasi wa fiber
Ulusi wa Galasi ndi chinthu chosakhala chachitsulo chomwe chimagwiritsidwa ntchito polimbitsa chingwe cholumikizira, chomwe chimapangidwa ndi zingwe zingapo zagalasi. Ili ndi kutsekereza kwabwino kwambiri komanso kukana kwa dzimbiri, komanso kulimba kwamphamvu kwambiri komanso kutsika pang'ono, zomwe zimapangitsa kuti ikhale yabwino pakulimbitsa zitsulo zopanda zitsulo mu zingwe zowunikira. Poyerekeza ndi zida zachitsulo, ulusi wa magalasi umakhala wopepuka ndipo supanga kupangitsidwa pakali pano, motero umakhala woyenera kwambiri pamizere yothamanga kwambiri komanso kugwiritsa ntchito chingwe cha kuwala m'malo onyowa. Kuonjezera apo, ulusi wa galasi wa galasi umasonyeza kukana kwabwino kwa kuvala ndi kukana kwa nyengo komwe kumagwiritsidwa ntchito, kuonetsetsa kuti chingwecho chikhale chokhazikika kwa nthawi yaitali m'madera osiyanasiyana.
