Ukwakhiwa Nokukhetha Okubalulekile Kwamabhodi E-FRP Amelene-nokugqwala: Ukugwema Izingibe – Lawa Maphuzu Abalulekile Athinta Ngokuqondile{1}}Imithelela Yokugqwala

Umthelela -wokugqwala kweAmaphaneli e-FRP anti{0}}e-corrosionakuxhomekile kuphela ngekhwalithi yomkhiqizo ngokwawo, kodwa futhi nokunemba kokukhethwa kwezinto ezibonakalayo kanye nokumiswa kokwakhiwa. Eminye imikhiqizo esezingeni eliphansi emakethe idluliswa{1}}njengeyekhwalithi ephezulu, futhi ukwakhiwa okungafanele kuvame ukuholela{2}ekuhlulekeni kokugqwala futhi kufinyeze impilo yesevisi. Lo mhlahlandlela uzokusiza ukuthi ukhethe imikhiqizo efanele futhi uqinisekise ukwakhiwa okufanele.

Ukuze ugweme izingibe lapho ukhetha izinto zokwakha, udinga ukubamba izimiso ezintathu ezibalulekile.

Okokuqala, cabangela uhlobo lwe-resin. Ekusetshenzisweni okujwayelekile, i-isophthalic polyester resin ingasetshenziswa, kanti ezintweni ezigqwala kakhulu (njengezindawo zokusebenzela zamakhemikhali), i-vinyl ester resin kufanele ikhethwe, njengoba inokusebenza okungcono{1}} kokubola nempilo yesevisi engaphezu kweminyaka engama-20. Gwema ukukhetha amabhodi angaphansi enziwe ngeresin egaywe kabusha, njengoba imikhiqizo enjalo izoqhekeka futhi inciphise ngesikhathi esifushane.

Okwesibili, hlola ukubukeka nemingcele. Amabhodi-ekhwalithi ephezulu avimbela ukugqwala{2}}anobuso obushelelezi, awekho amabhamuza noma imifantu, futhi ukujiya kwejeli elimelene nokugqwala kufana (Likhulu noma lilingana no-0.3mm). Hlola umbiko wokuhlola ukuze uqinisekise ukuthi ukumelana nokugqwala kwayo, amandla okudonsa kanye nezinye izinkomba kuhlangabezana nezinga le-GB/T 50212-2014.

Okwesithathu, imikhiqizo kufanele yenziwe ngokwezifiso ngokuya ngesimo esithile. Ukuze uthole umswakama ophezulu kanye nezimo zokugqwala okuphezulu, imikhiqizo enezimbotshana ezilwa -ezinezinhlangothi ezimbili ezimele ukugqwala kufanele zikhethwe. Ezindaweni ezinezidingo zokukhanya okuphezulu, amaphaneli aphikisayo{4}}okugqwala angakhethwa, futhi kufanele kuqashelwe ukuthi i-anti{5}}corrosion coating ayithinti indlela yokukhanya.

Izinqubo zokwakha ezisezingeni zibalulekile ngokufanayo. Ukulungiswa kwendawo efanele kubalulekile; izindawo zesakhiwo sensimbi kufanele zifakwe isihlabathi ukuze zifinyelele ebangeni le-Sa2.5 ukuze kuqinisekiswe ubuqhwaga obanele nokuvimbela izindawo ezingalingani ekubangeleni ukunamathela kwephaneli okuxekethile. Izibophelelo ezikhethekile zokunqanda{3}ukugqwala kufanele zisetshenziselwe ukulungisa; imigodi kufanele ibhojwe kuqala, ngobubanzi bembobo obungu-2-3mm obukhulu kunobubanzi besikulufu ukuze kuvunyelwe ukunwetshwa nokufinyela okushisayo. Ukushaya ngesando okuqondile akuvunyelwe ngokuphelele. Ukwelashwa ngokuhlanganyela kubalulekile ekuvimbeleni ukugqwala; ukugqagqana kwamaphaneli kufanele kube Kukhulu noma kulingane no-200mm, kube nezingqimba ezimbili zetheyiphu engangenwa amanzi kanye ne-anti-corrosion lapho kugqagqana khona, kulandelwe isitywini esikhethekile sokuvikela kabili. Isendlalelo esisodwa kuya kwezimbili zezinto eziqinisayo kufanele zengezwe emakhoneni ukuvimbela ukugxilisa ingqondo nokulimala. Indawo yokwakha kumele ilawulwe; izinga lokushisa kufanele libe phakathi kuka-15-30 degrees, futhi umswakama ohlobene akufanele udlule ama-85%. Ukwakhiwa kufanele kugwenywe ezimeni zemvula noma ezinomoya.
