Indima yeBorax ekunyibilikeni kwesinyithi

Kwihlabathi elintsonkothileyo nelinobuninzi be isinyithi Ukunyibilika, IBoraksi, ikhemikhali eyaziwa ngokuba yi-sodium tetraborate decahydrate, ivela njengento ebalulekileyo kunye nezinto ezininzi. Iipropathi zayo ezizodwa zeekhemikhali kunye nezomzimba ziyinika imisebenzi emininzi eyimfuneko enegalelo elibonakalayo ekusebenzeni, umgangatho, kunye nempumelelo yeenkqubo zokunyibilikisa isinyithi.

Isenzo se-Flux: Ukucoca kunye nokuQuquzelela ukuNyibilika

Enye yeendima eziphambili ze-borax ekunyibilikeni kwesinyithi isebenza njenge-flux. Kwinkqubo yokunyibilikisa, iintsimbi ezikrwada kunye nezilahlwa zesinyithi zihlala ziqulathe ubumdaka obahlukeneyo obufana nesilica, iioksidi, kunye nezinye izinto ezingezizo isinyithi. Oku kungcola kunokunyusa indawo yokuncibilika komxube wetsimbi, ukunciphisa ukunyibilika kokunyibilika, kwaye ekugqibeleni kuchaphazele umgangatho wemveliso yentsimbi yokugqibela.

I-Borax, xa ifakwe kwi-smelting charge, isabela kunye nale nkunkuma kumaqondo aphezulu. Ngokomzekelo, isabela nge-silica, enye yezona zinto zingcolileyo kwi-metal ores. I-chemical reaction phakathi kwe-borax kunye ne-silica yenza i-slag ye-borosilicate, enendawo ephantsi yokuncibilika kunesinyithi esinyibilikayo kunye nokungcola kwasekuqaleni. Le slag idada kumphezulu wentsimbi enyibilikisiweyo, yenza kube lula ukwahlula kwintsimbi ngokutyibiliza. Ngokususa obu kungcola, i-borax inceda ukuhlambulula isinyithi, ukuphucula iimpawu zayo zokwenza izinto, njengamandla, i-ductility, kunye ne-conductivity.

Ngaphezu koko, njenge-flux, i-borax iyanciphisa indawo yonke yokunyibilika komxube wokunyibilikisa. Oku akugcini nje ukusindisa amandla ngokufuna ubushushu obuncinane bokunyibilikisa isinyithi kunye nemathiriyeli ehambelana nazo kodwa kukwavumela iinkqubo zokunyibilika ezifanelekileyo. Ukushisa okuncinci okuncibilikayo kunokuthintela ukubunjwa kweengqungquthela ezingafunekiyo okanye ukuthotywa kweempawu zetsimbi ngenxa yokushisa okukhulu.

I-Deoxidation: Ukukhusela Intembeko yeNsimbi

Ngexesha lokunyibilika kwesinyithi, iintsimbi zivame ukuvezwa kwioksijini kwisithando somlilo, okukhokelela ekwenziweni kwee-oxide zetsimbi kwindawo yazo. Ezi oksidi zinokubangela iziphene kwimveliso yentsimbi yokugqibela, efana ne-brittleness kunye nokunciphisa ukuxhathisa kwe-corrosion. I-Borax idlala indima ebalulekileyo kwi-deoxidation.

I-Borax inokusabela ngee-oxide zetsimbi ezikhoyo kumphezulu wesinyithi esityhidiweyo. Inciphisa ezi oxide zentsimbi zibuyele kwimeko yazo yesinyithi, ngaloo ndlela ikhusela ingqibelelo yesinyithi. Ngokomzekelo, kwi-smelting yobhedu, i-borax inokusabela nge-copper oxide eyenziwe ngexesha lenkqubo. Ngokusebenzisa uthotho lweempendulo zemichiza, iguqula ioksidi yobhedu ibuyele kubhedu olusulungekileyo, ithintele ilahleko yentsimbi exabisekileyo kunye nokuqinisekisa umgangatho ophezulu wemveliso.

Ukugquma uMngundo kunye ne-Arhente yokuKhupha: Ukuphucula uMgangatho wokuCasa

Kwiinkqubo zokuphosa isinyithi, eziyinxalenye ebalulekileyo yokuvelisa isinyithi, i-borax ingasetyenziselwa njengengubo yokubumba kunye ne-agent agent. Xa isetyenziswe kumphezulu we-mold, i-borax yenza uluhlu oluncinci, olukhuselayo. Lo maleko unceda ukuthintela isinyithi esityhidiweyo ukuba singabambeleli kumphezulu wokungunda, kube lula ukukhululwa kwenxalenye yentsimbi etyhidiweyo xa sele iqinile.

Ukongezelela, i-borax yokugqoka kwi-mold inokusebenza njenge-insulator ye-thermal kwinqanaba elithile. Inceda ukulawula izinga lokupholisa kwentsimbi etyhidiweyo ekubumbeni, okubalulekileyo ekufezekiseni i-microstructure efanayo kwintsimbi etyhidiweyo. I-microstructure efanayo ngakumbi ikhokelela kwiimpawu ezingcono zomatshini zemveliso yokugqibela, njengamandla aphuculweyo kunye nozinzo lwe-dimensional.

Ukwahlula kunye noHlengahlengiso lweePropati

I-Borax inokuba negalelo kwinkqubo yokuxuba kwi-metal smelting. Nangona i-borax ngokwayo ayiqhelekanga njengento yendabuko edibeneyo, inokwazisa i-boron kwi-matrix yesinyithi ngexesha lokunyibilika. Ukongezwa kweBoron kwiintsimbi kunokuba nefuthe elibalulekileyo kwiipropati zabo.

Ngokomzekelo, ekuvelisweni kweentsimbi ezithile, ukongezwa kwexabiso elincinci le-boron, elingeniswa nge-borax, linokunyusa ukuqina kwentsimbi. Oku kuthetha ukuba intsimbi ingasebenza ngakumbi ubushushu - iphathwe ukufikelela ubunzima obuphezulu kunye namanqanaba amandla. I-Boron inokuphucula ukunganyangeki kunye nokumelana nokudinwa kwesinyithi, izenza zifaneleke ngakumbi usetyenziso kwiindawo ezinoxinzelelo oluphezulu, njengakwimizi-mveliso yeemoto kunye ne-aerospace.

Izicelo kwiinkqubo ezahlukeneyo zokunyibilikisa isinyithi

Ukusetyenziswa kwe-borax kwi-metal smelting akukhawulelwanga kuhlobo oluthile lwetsimbi. Isetyenziswa kakhulu ekunyibilikisweni kwesinyithi njengentsimbi kunye nentsimbi, kunye neentsimbi ezingenayo intsimbi ezifana nobhedu, ialuminiyam kunye nobhedu.

Kwimveliso yentsimbi kunye nentsimbi, i-borax inceda ukususa ukungcola kwi-iron ore kunye ne-scrap metal, ukuphucula ukucoceka kunye nomgangatho weemveliso zetsimbi zokugqibela. Kwishishini lokunyibilikisa ubhedu, lidlala indima ephambili kwi-deoxidation kunye nokususwa kokungcola, ukuqinisekisa ukuveliswa kweengcingo zobhedu eziphezulu kunye nezinye iimveliso zobhedu. Ukunyibilika kwe-aluminium, i-borax inokuncedisa ekuhlambululeni i-aluminium etyhidiweyo ngokususa i-oxides kunye nezinye izinto ezingcolileyo, kwaye ingasetyenziselwa kwinkqubo yokuphosa ukuphucula umphezulu wokugqitywa kwe-aluminium castings.

Ukuqukumbela, i-borax yinto engabalulekanga kwi-metal smelting. Imisebenzi yayo njenge-flux, i-deoxidizer, i-mold coating kunye ne-arhente yokukhulula, kunye negalelo layo kwi-alloying kunye nokuguqulwa kwepropathi iyenza ibe yinto ebalulekileyo kwimisebenzi eyahlukeneyo yesinyithi - ukunyibilikisa. Njengoko imveliso yesinyithi-esebenzayo iqhubeka nokuvela kwaye ifuna umgangatho ophezulu, iindlela zokuvelisa ezisebenza ngokufanelekileyo, indima yeboraksi ekunyibilikiseni isinyithi iya kuhlala ibalulekile, kwaye uphando olongezelelweyo lunokufumanisa usetyenziso olungakumbi kunye neenzuzo zale khompawundi imangalisayo.
