Ungawaphucula njani amandla kunye nokunamathela okunamathela kwesanti edityanisiweyo entlabathini?

1. Amanyathelo aphambili okuphucula amandla

a. Ulungelelwaniso lwenkqubo ye-resin kunye nenkqubo yokunyanga

Ukukhetha i-PERIK:

Ukukhetha inqanaba eliphezulu le-Polymerizolity Polymering Pisn I-Desage Desage ilawulwa nge-1.8% ~ 2.2% (umyinge wobunzima besanti eluhlaza), kwaye inokonyuka kwi-2.2% ~ 2.5% ye-SAPMODS okanye i-Subles.

Ngokusebenzisa i-resins eguqulweyo (njengokudibanisa inani elincinci le-epoxy okanye iarhente yokudibanisa i-seliling) yokuphucula i-Poind ye-Interfayili phakathi kwe-resin kunye namasuntswana asentlabeni anokunyuka nge-10% ukuya kwi-15%.

Unyango lokuhlengahlengiswa kwearhente:

I-Urotropin (Hexamethylenetetrorate) ikhethiwe njenge-arhente yokunyanga, inomthi we-12% ukuya kwi-15% yomxholo we-resin wongezwa ekuphuculeni i-resin fihlo kwaye inqande ukuguquguquka kwe-tems

b. Ulawulo lokuCwangciswa kweSand Sand kunye namasuntswana eSanti

Ukukhetha iSanti eluhlaza:

Ukusebenzisa i-quartz sand ngorhatya kunye nomgangatho ogudileyo (umjikelo ogudileyo> I-0.8) inokunciphisa izithuba ze-Angular kwi-Pronating Putter emva kokudibana, kwaye inyuse amandla kubushushu begumbi nge-5% ukuya kwi-8%; Kulumkele ukusebenzisa intlabathi yobuqhetseba kunye nomxholo wodaka olukhulu kune-0.2% ukunqanda ukungcola kwe-Clay kwi-Pisn Bondling.

Ubungakanani beenkozo:

Sebenzisa i-parical ye-tall okanye i-paricle ye-paricle (enjengokuxuba i-50/11 Mesh kunye ne-70/40 mesh kumyinge we-7: 3) ukugcwalisa amasuntswana asentlabathi, i-95%, kwaye amandla aphuculwe ngokulandelelana.

c. Inkqubo encedisiweyo

Inkqubo yokuDibanisa iFizilifiling:

Lawula amaqondo obushushu aqengqelekayo nge-180-200 ℃ kunye nexesha lokukhathalela i-READ kwi-3-5 imizuzu yokuqinisekisa iyunifomu kunye nefilimu ye-REn (8-8 μ) yenziwa kumphezulu wamasuntswana entlabathi, ukuphepha ukucofa okanye ukuqokelela.

Ulawulo lokuqina:

Ukwamkela ukuqhuma kwentlabathi okanye i-chibiction plastic probrection Inkqubo yokudibanisa, ukungcola kwesanti esezantsi yi-95%, kunye nokudityaniswa kwesanti ephezulu yi-90%, ukunqanda ukukhululeka kunye namandla awoneleyo.

I-2. Indlela engundoqo yokuphucula amandla okumelana nesanti

a. Ukuphucula ukumelana ngomlilo kunye neepropathi zomqobo

I-SEPCORCOTORICROTOR YOBUCHULE BOKUGQIBELA NEZOBUCHULE:

Sebenzisa i-zircon sind (ngomlilo we-1850 ℃) okanye isanti ye-chromite (i-1800) endaweni ye-quitz, okanye udibanise i-5% ye-5% ye-5% ye-5% ye-Bauxite kwi-Iron ePhezulu kunye namasuntswana e-SADNE Iinyibiba zendawo ezinyibilikayo (ezinjenge-feo ·).

I-InErt Powder Yongeza:

Yongeza i-2% ukuya kwi-4% i-facke i-graphite powder okanye i-molybdenum dispide (mosbdenum ifilimu (i-mos ₂) ukwenza ifilimu yekhabhoni ephezulu, ukunciphisa ukungafihli Kwangelo xesha, ukuqhubela komdlalo wegrafu kunokukhawulezisa ukungavisisani kwezandla zasekhaya kwaye kucothise amaqondo obushushu amaqondo obushushu anentsimbi yentsimbi etyhidiweyo.

b. Yenza iNkqubo yokuThengiswa

Ukuqiniswa kokuthintelwa:

Ibrashi ye-zurcon powder caider (uxinzelelo lwe-40% 50%) okanye i-raphenes esekwe kumphezulu wentlabathi ye-0.3 ~ 0.5mm, ukwenza umqobo; I-1% ~ 2% ye-Boric acid inokongezwa kwi-commating ukuvelisa isigaba seglasi kwiqondo lobushushu, elizalisa izithuba phakathi kwamasuntswana esinenti.

I-antitive yesanti yesanti ye-Anti.

Yongeza i-1% ukuya kwi-2% Calconam Carbonate (CACO) okanye i-Ignesium Carbonate (MGCO) ukuya kwizithako, eziya kuthi zenze ifilimu yegesi, ithembisa i-bible yentsimbi yentsimbi ye-nyibili yentsimbi; I-cao kunye ne-MGO yaveliswa ngokuthobeka ngaxeshanye inokusabela nge-geo kwi-feo kwintsimbi ye-molten, ukunciphisa i-screation ye-scocicmation.

c. Ukulawulwa kwegesi yegesi kunye nentlabathi yesanti

Ifomula yokukhupha i

Yomisa isanti eluhlaza ngo-200 ukuya kwi-50 ℃ iiyure ezi-2 ngaphambi kokusebenzisa ukususa umswakama kunye nezinto eziphilayo; I-resin ikhethwe njengendawo yokukhupha irhasi ye-phenolin, enenqanaba lokukhutshelwa kwegesi elingaphantsi kwe-20ml / g, ukunqanda ukuthathwa kwesanti kunye nokungenisa i-iron ekhulayo kwiqondo lokuhlala libangelwa yirhasi.

Ukwahlula-hlulwa kunye namandla okulinganisa:

Yongeza i-0.5% ye-1% ye-Barium ye-Barium ye-Balium Kwangelo xesha, qinisekisa ukomelela kobushushu obuphezulu (amandla e-thensle> 0.8MPA nge-800 ℃) ukunqanda ukuthathwa kwesanti.

3. Isicwangciso sokusebenzela intsebenziswano (amandla okulinganisa kunye nokuxhathisa kwesanti)

IFomula Couling Uhlengahlengiso:

Umzekelo, umxube we-zircon ye-zircon sind (i-60%) kunye nentlabathi ye-quartz (40%), i-2% ye-pinopin, iqinisekisa i-pidropin ye-pinopin, iqinisekisa ukucinezela isanti enamathele kwi-magnesia isanti kunye negrafu.

Inkqubo yokuqinisekiswa kunye nokuThengisa:

Thelekisa izicambulo kunye neefom ezahlukeneyo ngexesha lokuvelisa uvavanyo:

Ukuvavanywa kwamandla: Amandla okujolisa kubushushu begumbi yi-1.2-1.5MPA, kunye namandla ashushu nge-800 ℃ inkulu kune-0.8MPA;

Isiphumo se-Anti Sand Mathesion: Isusa isiphoso kwaye siqwalasele ubukhulu besanti sesanti. Umgangatho ofanelekileyo ngu <0.5mm, kunye ne-ratity rathi ra yi-25 μ μ M. m.

ISISHWANKATHELO:

Amandla kunye nesanti yesanti sesanti yesanti kufuneka ifezekiswe ngokulandelelana kwe "Redin Renlint eqingqiweyo, umqobo wezinto ezibonakalayo, kunye nokunikezelwa kwengxelo yokuphendula". Kwimveliso yokwenyani, ukuguqulwa kwakhona kwakhona kunye nentlabathi ephezulu yesanti ephambili inokusetyenziselwa ukuphucula intsebenzo esisiseko, kwaye emva koko idityaniswe nemveliso kunye neewonge ezongezelelekileyo zokuthintela ubuchule besanti inamathela kwi-Anti ibeka amandla enti. Kwangelo xesha, isizukulwana segesi kunye nokungahambi kakuhle kunokulawulwa kukuphepha ukwanda kwesanti esinamathela ngenxa yokungabi nako ukungathobeki ngokwaneleyo.
