Kodi mikhalidwe yayikulu ya mapaipi a fiberglass ndi chiyani?

1. Kukana kwa dzimbiri bwino. Popeza zida zazikulu za FRP zimapangidwa ndi unsaturated polyester resin ndi utomoni wagalasi wokhala ndi polima wambiri, zimatha kukana dzimbiri la acid, alkali, mchere ndi media zina, komanso zimbudzi zapakhomo zosagwiritsidwa ntchito, dothi lowononga, madzi otayira amankhwala ndi zina. mankhwala amadzimadzi ambiri. Kukokolokako, kawirikawiri, kumatha kukhalabe otetezeka kwa nthawi yayitali.

2. Kukana kukalamba kwabwino komanso kukana kutentha. The galasi CHIKWANGWANI chubu angagwiritsidwe ntchito kwa nthawi yaitali mu kutentha osiyanasiyana -40 ℃～70 ℃, ndi kutentha kusamva utomoni ndi chilinganizo chapadera angathenso ntchito bwinobwino pa kutentha pamwamba 200 ℃.

3. Kuchita bwino kwa antifreeze. Pansi pa 20 ℃, chubu sichimazizira pambuyo pozizira.

4. Kulemera kwakukulu ndi mphamvu zambiri. Kachulukidwe wachibale ali pakati pa 1.5 ndi 2.0, yomwe ili 1/4 mpaka 1/5 yokha ya chitsulo cha kaboni, koma mphamvu yamakomedwe imakhala pafupi kapena kuposa ya chitsulo cha kaboni, ndipo mphamvu yeniyeniyo ingafanane ndi ya zitsulo zamtengo wapatali za alloy. Chifukwa chake, imakhala ndi zotsatira zabwino kwambiri pakuuluka, maroketi, zombo zapamlengalenga, zombo zothamanga kwambiri ndi ntchito zina zomwe zimafunikira kuchepetsa thupi.

5. Designability wabwino.

Mitundu yosiyanasiyana yamapangidwe imatha kupangidwa mosinthika kuti ikwaniritse zofunikira zogwiritsidwa ntchito, zomwe zingapangitse kuti mankhwalawa akhale ndi kukhulupirika kwabwino.

6. Good kuvala kukana. Madzi okhala ndi matope ambiri, mchenga ndi miyala amayikidwa mu chitoliro kuti achite mayeso ofananiza a momwe amavalira mozungulira. Pambuyo pa kasinthasintha 3 miliyoni, kuya kwa khoma lamkati la chubu chodziwikiratu ndi motere: 0.53mm pa chubu chachitsulo chokutidwa ndi phula ndi enamel, 0.52mm chubu chachitsulo chokutidwa ndi epoxy resin ndi phula, ndi chubu chachitsulo chagalasi. chubu chachitsulo cholimba kwambiri ndi 0.21mm. Zotsatira zake, FRP ili ndi kukana kwabwino kovala.

7. Kutsekemera kwabwino kwa magetsi ndi kutentha. FRP si kondakitala, kutchinjiriza magetsi paipi ndi bwino, ndi kutchinjiriza kukana ndi 1012-1015Ω.cm. Ndiwoyenera kwambiri kutumizira magetsi, madera owundana ndi ma telecommunication komanso madera ambiri amigodi. Kutentha kwapang’onopang’ono kwa FRP ndi kochepa kwambiri, kokha 0.23, yomwe ndi chikwi chimodzi chazitsulo. Zisanu mwa zisanu, payipi imakhala ndi ntchito yabwino kwambiri yotsekera matenthedwe.

1. Kukana kukangana kwakung’ono ndi kunyamula kwakukulu. Khoma lamkati la chitoliro cha FRP ndi losalala kwambiri, ndipo khwimbi ndi kukana kukangana ndizochepa kwambiri. The roughness factor ndi 0.0084, pomwe mtengo wa n ndi 0.014 wamapaipi a konkriti ndi 0.013 wamapaipi achitsulo
