Ifayibha yeBasaltUmbhobho oxineneyo oxineneyo, oneempawu zokuxhathisa ukugqwala, ubunzima obulula, amandla aphezulu, ukumelana okuphantsi kokuthutha ulwelo kunye nobomi benkonzo ende, usetyenziswa kakhulu kwi-petrochemical, kwiinqwelomoya, ekwakheni nakwamanye amasimi. Iimpawu zayo eziphambili zezi: ukumelana nokugqwala kwi-H2S, CO2, amanzi anetyuwa, njl.njl., ukwakheka okuphantsi, ukwakheka kwe-wax ephantsi, ukusebenza kakuhle kokuhamba, i-flow coefficient iphindwe kayi-1.5 kuneyombhobho wentsimbi, kwaye kwangaxeshanye, inamandla amahle oomatshini, ubunzima obulula, iindleko zokufakela eziphantsi, ubomi benkonzo yoyilo obungaphezulu kweminyaka engama-30, kwaye kwezinye iiprojekthi, kwaye nokusetyenziswa kweminyaka engama-50 akukabi yingxaki. Izicelo zayo eziphambili zezi: ioyile ekrwada, igesi yendalo kunye nemibhobho yokuhambisa amanzi acocekileyo; inaliti yamanzi amdaka, umbhobho weoyile ongaphantsi kunye neminye imibhobho yoxinzelelo oluphezulu; imibhobho yenkqubo ye-petrochemical; imibhobho yokuhambisa amanzi amdaka ase-oyile kunye namanzi amdaka; umbhobho wemithombo eshushu njalo njalo.
Inkqubo Ephambili:
Uthelekiso kunye nomahluko phakathii-fiberglasskunye nombhobho woxinzelelo oluphezulu lwefayibha ye-basalt:
(1) ifayibha yenkcazelo efanayo, indlela efanayo, izixhobo ezifanayo kunye nenkqubo yazo yokuqinisekisa umahluko phakathi koxinzelelo lwe-hydrostatic lombhobho wefayibha ye-basalt fiber/glass fiber (DN50PN7, umzekelo, ukumelana noxinzelelo lwe-EP/CBF malunga ne-30MPa, ukumelana noxinzelelo lwe-EP/GF malunga ne-25MPa); inqanaba elifanayo loxinzelelo, ifayibha ye-basalt xa ithelekiswa nefayibha yeglasi ukunciphisa indlela yokuhambahambahambayo ye-10%, i-20% ukuqinisekisa inqanaba lokwenyani lokumelana noxinzelelo lwe-hydrostatic (ukuya kwi-DN50PN7). Umzekelo, nciphisa iileya ezi-2 zokumelana noxinzelelo lwe-EP / CBF malunga ne-25MPa).
(2) Uvavanyo lokugqibela emva kokunciphisa indlela yendlela ukuze kuncitshiswe ukusetyenziswa ngokubanzi kwezinto ezikrwada ukunciphisa iindleko zemveliso lulawulwa, inqanaba lokumelana noxinzelelo lombhobho lisahlangabezana neemfuno zoyilo, ixabisoumbhobho wefiberglassxa kuthelekiswa nokungabikho kokunyuka okukhulu.
Iingenelo zokusebenza kombhobho oxinzelelweyo ophezulu we-basalt fiber:
(1) ukumelana nokugqwala okugqwesileyo
Ifayibha yeBasaltIsakhiwo semibhobho enoxinzelelo oluphezulu sahlulwe saba ngumaleko we-lining, umaleko wesakhiwo kunye nomaleko wokukhusela wangaphandle onamacandelo amathathu. Phakathi kwazo, umaleko we-lining unomxholo ophezulu we-resin, ngokubanzi ungaphezulu kwe-70%, kwaye umxholo we-resin womphezulu wayo otyebileyo we-resin uphezulu malunga ne-95%. Xa kuthelekiswa nombhobho wentsimbi, unokumelana nokugqwala okuphezulu kakhulu, njengeentlobo ngeentlobo ze-asidi ezinamandla kunye ne-alkalis, iintlobo ngeentlobo zetyuwa ezingaphiliyo, i-oxidizing media, i-hydrogen sulfide, i-carbon dioxide, iintlobo ngeentlobo ze-surfactants, izisombululo ze-polymer, iintlobo ngeentlobo ze-organic solvents, njl.njl., lo gama nje ukhetho lwe-resin matrix elungileyo, umbhobho woxinzelelo oluphezulu we-basalt fibers unokuba nokumelana kwexesha elide (i-acid egxininisiweyo, i-alkali enamandla, kunye ne-HF ayifakwanga)
(2) Ukumelana nokudinwa okuhle kunye nobomi benkonzo ende
Ubomi benkonzo yoyilo lwepayipi ye-basalt fiber ephezulu yoxinzelelo oluphezulu bungaphezulu kweminyaka engama-20, kwaye eneneni, idla ngokuba semva kweminyaka engaphezu kwama-30 yokusetyenziswa, kwaye ubomi bayo benkonzo abunakugcinwa.
(3) Umthamo ophezulu wokuthwala uxinzelelo
Inqanaba eliqhelekileyo loxinzeleloifayibha yebasaltUmbhobho woxinzelelo oluphezulu yi-3.5MPa-25MPa (ukuya kuthi ga kwi-35 MPa, ngokobukhulu bodonga kunye nokubala), xa kuthelekiswa neminye imibhobho engeyiyo eyesinyithi, amandla okumelana noxinzelelo aphezulu.
(4) Ubunzima obulula, ukufakwa okulula kunye nokuthuthwa
Umbhobho oxinzelelweyo ophezulu we-basalt fiber umbhobho oxinzelelweyo umalunga ne-1.6, umbhobho wentsimbi okanye umbhobho wesinyithi ophoswe kuphela yi-1/4 ~ 1/5, ukusetyenziswa okusebenzayo kubonisa ukuba, phantsi koxinzelelo lwangaphakathi olufanayo, ububanzi obufanayo, ubude obufanayo bombhobho we-FRP, ubunzima bawo bumalunga ne-28% yombhobho wentsimbi.
(5) amandla aphezulu, iipropati ezifanelekileyo zoomatshini
I-Basalt fiber high-pressure pipe strength of 200 ~ 320MPa, kufutshane nombhobho wentsimbi, kodwa ngaphezu kwamandla aphindwe kane, kuyilo lwesakhiwo, ubunzima bombhobho bunokuncipha kakhulu, ukufakwa kulula kakhulu.
(6) Ezinye iipropati:
Akulula ukukala kunye newax, ukumelana nokuhamba kwamanzi okuphantsi, iipropati ezilungileyo zokuthintela umbane, uqhagamshelo olulula, amandla aphezulu, ukuqhuba kobushushu obuphantsi, uxinzelelo oluphantsi lobushushu.
