Ubwino wa nkhungu ya FRP umagwirizana mwachindunji ndi momwe chinthucho chikuyendera, makamaka pankhani ya kuchuluka kwa kusintha, kulimba, ndi zina zotero, zomwe ziyenera kufunikira kaye. Ngati simukudziwa momwe mungazindikire ubwino wa nkhungu, chonde werengani malangizo ena m'nkhaniyi.
1. Kuyang'ana pamwamba pa nkhungu kumachitika ikafika, ndipo pamafunika kuti pasakhale mawonekedwe a nsalu pamwamba pake;
2. Kukhuthala kwa gel yophimba nkhungu ndi kwakukulu kuposa kapena kofanana ndi 0.8mm, ndipo makulidwe a gel yophimba ndi makulidwe a gel yophimba pambuyo pokonza ndi kupanga, osati makulidwe a filimu yonyowa;
3. Sipayenera kukhala utomoni woyikidwa pamwamba pa ngodya ya nkhungu.
4. Thupi lalikulu la nkhungu, ndiko kuti, kutentha kwa kutentha kwa FRP laminate, malinga ndi parameter ya resin ya 2001 ≥110℃.
5. Kunyezimira ndi kusalala kwa pamwamba pa gel coat ndikofunikira kuti ifike pamwamba pa A-level. Pa malo opingasa, mawonekedwe ake amatha kuwonetsedwa bwino popanda kusintha.
6. Zofunikira pa kuuma kwa pamwamba pa jeli: mtengo wapakati wa kuuma kwa basi wa ma point 10 ofalikira omwe amayesedwa ndi thupi la nkhungu ndi woposa 35.
7. Mkhalidwe wa pamwamba pa nkhungu sufuna thovu pamwamba pa nkhungu, osapitirira thovu zitatu mkati mwa 1m2 ya thovu looneka mu gel coat ndi mold laminate; osalemba mabala oonekera bwino a burashi, mikwingwirima ndi zizindikiro zokonzanso pamwamba pa nkhungu, ndipo osapitirira mabowo asanu mkati mwa 1m2 kuchokera pamwamba. A, sipangakhale chochitika chogawa.
8. Chitsulo chachitsulo cha nkhungu ndi choyenera, ndipo chiyenera kukhala ndi chimango chonse. Pulatifomu yolumikizira iyenera kukhala yolimba komanso yosasinthika mosavuta; chipangizo cha hydraulic chimatseguka ndi kutseka bwino komanso bwino, liwiro limasinthidwa, ndipo pali chosinthira choyendera, chomwe chingakwaniritse nthawi yotsegulira ndi kutseka yoposa nthawi 1000 pakugwiritsa ntchito mwachizolowezi.
9. Chikombolecho chimapangidwa motsatira njira yochotsera utsi wa chinthucho, makulidwe a thupi lalikulu amafunika kufika pa 15mm, ndipo makulidwe a flange ya chikolecho amafunika kukhala ≥18mm.
10. Mapini oikirapo nkhungu ndi mapini achitsulo, ndipo mapini ndi zigawo za FRP ziyenera kutsekedwa.
11. Mzere wodulira wa nkhungu umawunikidwa mosamala malinga ndi muyezo wazinthu.
12. Kukula kofanana kwa nkhungu kuyenera kukhala kolondola, ndipo cholakwika chofanana pakati pa zigawo zofanana chiyenera kukhala ≤1.5mm.
13. Nthawi yanthawi zonse ya ntchito ya nkhungu siyenera kupitirira ma seti 500 a zinthu.
14. Kusalala kwa nkhungu ndi ±0.5mm pa mita imodzi, ndipo sipayenera kukhala kusalingana.
15. Miyeso yonse ya nkhungu imatsimikizika kuti ili ndi cholakwika cha ± 1mm, ndipo palibe burr pamwamba pa laminate.
16. Pamwamba pa nkhungu sipaloledwa kukhala ndi zolakwika monga mabowo ang'onoang'ono, mapangidwe a mapeyala a lalanje, mikwingwirima ya sandpaper, ming'alu ya mapazi a nkhuku, ndi zina zotero, ndipo mzerewo uyenera kukhala wosalala.
17. Nkhungu imachotsedwa kutentha kwa 80°C, kenako imachotsedwa patatha maola 8.
18. Chidebecho sichingasinthidwe ndi kutentha kwa exothermic peak kwa 90℃-120℃, ndipo pamwamba pake sipangakhale zizindikiro zocheperako, ming'alu, ndi kusalingana.
19. Pakati pa chimango chachitsulo ndi nkhungu payenera kukhala mpata woposa 10mm, ndipo cholumikizira cha matupi awiriwa chiyenera kuphimbidwa ndi cork kapena matabwa ambiri okhala ndi makulidwe ofanana.
20. Cholumikizira cha nkhungu yolekanitsa sichingasunthike, kapangidwe kake ka malo a nkhungu ndi koyenera, nkhungu imatulutsidwa, ntchito ya chinthucho ndi yosavuta, ndipo nkhunguyo ndi yosavuta kutulutsidwa.
21. Kupanikizika konse kwa nkhungu kumakhala pansi pa 0.1, ndipo kupanikizika kumasungidwa kwa mphindi 5.
