Ukunyuka kweBasalt Fiber
Ifayibha yeBasalt, efinyeziweyo njenge-CBF, yifayibha eqhubekayo engeyiyo i-metallic engaphiliyo eveliswa kuphela kwi-basalt ore ngokusebenzisa iinkqubo zokunyibilika nokutsala ubushushu obuphezulu. Ayinazo nje kuphela iipropati ezintle zoomatshini, ezinje ngamandla aphezulu kunye ne-modulus ephezulu, kodwa ikwabonisa okulungileyo. Ikhemikhali uzinzo, ukumelana nobushushu obuphezulu, kunye neenzuzo zeendleko. Njengezinto ezibalulekileyo zokuqinisa izimbiwa kunye nezinto zokwakha eziluhlaza, i-basalt fiber ijoyine ngempumelelo uluhlu lwezinto ezine eziphambili zefayibha zelizwe lam zophuhliso (kunye ne-carbon fiber, i-aramid fiber, kunye ne-polyethylene fiber enobunzima obuphezulu kakhulu).
Inkqubo yokulungiselela i-basalt fiber ibandakanya amanqanaba aliqela abalulekileyo, kuquka ukukhethwa kwezinto, ukugaya, ukunyibilika, kunye nokutsalwa. Inqanaba lokukhetha izinto lifuna iindawo ezaneleyo zokugcina i-ore eluhlaza kunye neempawu zokusebenza ezihlangabezana nemigangatho; inqanaba lokugaya libandakanya ukutyumza izinto eziluhlaza, ukwahlulwa kwemagnethi, kunye nokuxuba okufanayo; ngexesha lenkqubo yokunyibilika, izinto eziza kusetyenziswa kufuneka zitshiswe zifikelele kuma-900℃, emva koko zifudunyezwe zibe ngama-1300–1400℃ kwisithando sombane; ekugqibeleni, ukunyibilika kutsalwa kwiifayibha ngenkqubo yokuzoba, kwaye emva koko kuhlanganiswe kwimveliso esisilinda ngezixhobo ezifana ne-agent yokulinganisa, i-bundler, i-fiber tensioner, kunye nomatshini wokujija ozenzekelayo. Kubalulekile ukuqaphela ukuba ukwakheka kweekhemikhali ze-basalt ore kunempembelelo enkulu kwizalathisi zokusebenza ezenza ifayibha. Umxholo wesinyithi ogqithisileyo unokukhokelela ekungeneni kakuhle kobushushu kunye nokunyibilika okungaphelelanga kwe-basalt melt, ngaloo ndlela kunciphisa ukusebenza kakuhle kokunyibilika. Ngaphezu koko, izinto zendalo ezifana nokwahluka kokwakheka kwe-basalt deposit kunye ne-crystallization yangaphakathi engalinganiyo nazo zinokuchaphazela umgangatho wefayibha. Ngexesha lokufudumeza, ii-iron oxides ezixineneyo ziqokelelana kwi-platinum-rhodium alloy perforator ezantsi kwesitovu, nto leyo ebangela iingxaki zokukhukuliseka. Kwangaxeshanye, i-basalt inomlinganiselo wobushushu obuncinci bokwenza i-fiber, apho ubushushu be-crystallization buhambelana nobushushu obudwebayo; le nto ye-crystallization ichaphazela kakubi amandla okuxinana kwe-fiber.
Uthelekiso oluPhambili lweBasalt Fiber kunye nezinye iiFiber
Ifayibha yeBasalt, eneempawu zayo ezikhethekileyo, ivele njengenkokeli kwi Ilula, izixhobo ezidityanisiweyo ezinamandla aphezulu. Ayigcini nje ngokuba namandla okutsalwa kunye ne-elastic modulus kodwa ikwanobomi obude benkonzo, iimpawu ezingenangcoliseko, uluhlu olubanzi lobushushu bokusebenza, kunye nokufunxwa komswakama okuphantsi. Phakathi kwezinto ezininzi zefayibha, ifayibha ye-basalt ivelele kuba isebenzisa kuphela izinto zemvelo eziluhlaza zeminerali enye, kwaye inkqubo yayo yokuvelisa inobuhlobo nokusingqongileyo, ayifuni zongezo.
Okulandelayo, siza kujonga iimpawu zesakhiwo, iingenelo zokusebenza, kunye nobuchule bokusetyenziswa kwe-basalt fiber kwiinkalo ezahlukeneyo.
(1) Inkqubo yoLungiso lweArhente yoQhagamshelo
Ukuguqulwa kwee-coupling agent kusetyenziswa kakhulu ukuphucula ukusebenzisana kwezinto ezidityanisiweyo, ngaloo ndlela kuphucula iimpawu zazo zoomatshini, ubushushu, kunye nombane. Le nkqubo isebenzisa isiphumo "sokubhida" see-coupling agents ukudibanisa izinto ezahlukeneyo, ukuphucula ukuhambelana kwazo.
(2) Inkqubo yoLungiso lwe-Nano-Modification kunye ne-Coupling Agent edibeneyo
Ii-composites ze-basalt fiber zinokuphuculwa ngakumbi ngenkqubo edibeneyo yokuguqulwa kwe-nano kunye nokuguqulwa kwe-coupling agent. Le nkqubo yokuguqulwa edibeneyo ingasebenzisa ngokupheleleyo iipropati ezintle ze-basalt fiber kwaye yandise iindawo zayo zokusetyenziswa.
I-basalt fiber inamandla okusetyenziswa kwiindawo ezininzi.
Umzekelo, kwishishini leekhemikhali, ingasetyenziswa njengezinto ezimelana nokugqwala; kwishishini leemoto, ingasetyenziswa njengezinto ezimelana nokugqwala nokungqubana, kunye neendawo ekujoliswe kuzo ezimelana neempembelelo ezikhawulezayo; kwicandelo lokwakha, ifayibha ye-basalt inokonyusa amandla kunye nokuqina kwekhonkrithi kunye nesamente. Ngaphezu koko, ifayibha ye-basalt ikwanokumelana okuhle kakhulu nobushushu obuphezulu, okwenza ukuba ifaneleke kwi-insulation yobushushu obuphezulu, ukuthintela umlilo, kunye nokumelana nobushushu kwishishini leemoto. Okulandelayo, siza kuhlola ngokweenkcukacha ukusetyenziswa kwefayibha ye-basalt kwiinkalo zezixhobo zokwakha kunye nobunjineli bokwakha. Kwizakhiwo, ifayibha ye-basalt ingasetyenziselwa ukuvelisa iiprofayili eziqhekekileyo okanye imivalo yokuqinisa ikhonkrithi. Inamandla kwaye ilula kunentsimbi, ngelixa inokumelana kwendalo kwi-alkalis, umhlwa, kunye nee-asidi. Ngaphezu koko, ifayibha ye-basalt inomlinganiselo ofanayo wokwandiswa kobushushu njengekhonkrithi, okwenza kube lula ukuyisika ibe bubude obuthile, ilungele ukusetyenziswa kolwakhiwo.
Ngokufanayo, i-basalt fiber idlala indima ebalulekileyo kubunjineli beendlela. Ingasetyenziswa njengesixhobo sokuqinisa i-asphalt concrete, iphucula ngempumelelo amandla okuxinana, ukuqina, kunye nokumelana nokuguqulwa kwendlela.
Ukongeza, i-basalt fiber ibonisa ukusebenza okugqwesileyo kwicandelo le-petrochemical. Iyakwazi ukumelana nokukhukuliseka kweegesi ze-organic, inika ukhetho olutsha lwezinto zokwakha ioyile negesi. Umzekelo, iimveliso ezintsha kunye neenkqubo zezinto ze-basalt fiber ezikhaphukhaphu, ezinamandla aphezulu kunye nee-composites zinokuphuhliswa ukuze kuthuthwe ioyile negesi ngemibhobho, ulwelo olushushu nolubandayo, kunye nezinto ezinkulu, kunye nokwenziwa kwemibhobho ye-hydrogen enoxinzelelo oluphezulu, ekude.
Ukuqukumbela, i-basalt fiber, eneempawu zayo ezikhethekileyo kunye namandla ayo okusetyenziswa ngokubanzi, idlala indima ebaluleke ngakumbi kwiinkalo ezahlukeneyo. Ngokuqhubeka kweteknoloji, kulindeleke ukuba amathuba okusetyenziswa kwe-basalt fiber abe banzi nangakumbi.
