China OEM caadadii graphite spheroidal tuurista qolof birta alaabta tuurista leh adeegyadaMashiinka CNC, daaweynta kulaylka iyo daaweynta dusha sare.
Dhalinta qolofkahabka waxa kale oo loo yaqaan habka shubista xabagta hore loo dahaadhay, shubista qolof kulul ama habka shubista xudunta u ah. Walaxda ugu weyn ee wax lagu dhejiyo waa ciidda xabagta phenolic ee horay loo dahaadhay, taas oo ka qaalisan ciidda cagaarka ah iyo ciidda xabagta furan. Waxaa intaa dheer, ciiddan dib loo warshadayn karo lama isticmaali karo.
Habka shubista ciidda is-adkeysiinaya resin Furan (nooca nobake) wuxuu isticmaalaa ciidda dahaarka leh ee furan si uu u sameeyo caaryada tuurista. Ka dib marka la qaso cammuudda asalka ah (ama ciidda dib loo soo celiyay), dareeraha furan ee dareeraha ah iyo dareeraha dareeraha si siman, oo ku buuxi sanduuqa xudunta u ah (ama sanduuqa ciidda), ka dibna adkee si aad u dhuujiso caaryada ama caaryada sanduuqa xudunta u ah (ama ciid). sanduuqa) heerkulka qolka. Dabadeed waxaa la sameeyay caaryada tuurista ama xudunta tuurista, taas oo loo yaqaanno is-adkeysi qabow-core sanduuqa (core), ama habka is-adkeysi (core).
Sababtoo ah caaryada waxay ku sameysan tahay heerkulka qolka oo aan loo baahnayn in lagu kululeeyo, isku-adkaynta ciidda isku-xoojinta waxaa sidoo kale loo yaqaan habka wax-dubidda. Habka is-adkeysigu waxa loo qaybin karaa xashiish-catalyzed furan resin-catalyzed iyo habka phenolic cammuudda is-adkeysi, habka is-adggeynta xabka kaadida iyo habka monoester is-adkeysi.
Ciidda sanduuqa qaboojiyaha ee is adkeeya, ciid xabagta furan ayaa ah tii ugu horreysay oo hadda loogu isticmaalka badan yahay ciid-xidhaha-isku-xidhaha ee Shiinaha. Qadarka resinka lagu daray ciidda wax-ku-beddelka guud ahaan waa 0.7% ilaa 1.0%, iyo xadiga resinka lagu daray ee ciidda xudunta u ah guud ahaan waa 0.9% ilaa 1.1%. Waxa ku jira aldehyde bilaashka ah ee xabagta furan waxa ay ka hoosaysaa 0.3%, warshadaha qaarna waxa ay hoos uga dhaceen 0.1%. Aasaaska Shiinaha, ciidda furan ee resin is adkeysi waxay gaartay heer caalami iyadoon loo eegin habka wax soo saarka iyo tayada dusha sare ee shubka.
Birta shubka ah, oo sidoo kale loo yaqaan birta kabka nodular, graphite graphite cast iron ama kaliya SG birta gaaban, waxay ka dhigan tahay koox bir ah oo shub ah. Birta kabka ah ee nodular waxay ku helaysaa garaafka nodular iyada oo loo marayo spheroidization iyo daaweynta tallaalka, taas oo si wax ku ool ah u wanaajisa sifooyinka farsamada ee birta kabka, gaar ahaan caagagga iyo adkaanta, si loo helo xoog ka sarreeya birta kaarboonka.
Tuubitaanka birta kaarboonku waxay leeyihiin waxqabadka nuugista shoogga ee ka wanaagsan birta kaarboonka, halka kaarboonka birta ah ay leeyihiin alxanka aad uga wanaagsan. Iyo ilaa xad, shubista ductile iorn waxay yeelan kartaa qaar ka mid ah bandhigyada u adkaysta xidhashada iyo miridhku. Markaa shubista birta ductile waxaa loo isticmaali karaa qaar ka mid ah guryaha bamka ama nidaamyada biyaha. Si kastaba ha ahaatee, waxaan wali u baahanahay inaan sameyno taxadar si aan uga ilaalino xirashada iyo miridhku.
Ductile iron ma aha hal shay, laakiin waa qayb ka mid ah koox maaddooyin ah oo la soo saari karo si ay u yeeshaan hanti aad u ballaadhan iyada oo la xakameynayo qaab-dhismeedka yar yar. Tilmaamaha guud ee qeexida kooxdan agabku waa qaabka garaafka. In birta ductile, graphite waa qaab nodules halkii ay ka jajabin lahaa sida ay ku jirto birta cawl. Qaabka fiiqan ee garaafyada garaafyada waxay abuuraan dhibco fiirsiyeedka gudaha matrixka birta iyo qaabka wareegsan ee qanjidhada si ka yar, sidaas darteed xannibaya abuurista dildilaaca iyo bixinta ductility la xoojiyay ee siinaya daawaha magaceeda. Marka guud ahaan marka la hadlo, haddii birta ductile ay buuxin karto shuruudahaaga, birta ductile waxay noqon kartaa doorashadaada koowaad, halkii aad ka heli lahayd birta kaarboon ee shubka.

Faa'iidooyinka Kaabista Dhalinta Isku-adkaynta ee Furan Resin Dahaarka leh:
1) Hagaajinta saxnaanta cabbirka ee shubista iyo qallafsanaanta dusha sare.
2) Adkeynta caaryada (core) ciid uma baahna qallajin, taas oo badbaadin karta tamarta, iyo sanduuqyada alwaax ama caag ah oo jaban ayaa sidoo kale la isticmaali karaa.
3) Ciidda is-adkeysigeedu way fududahay in la isku xidho oo burburto, si fudud loo nadiifiyo wixii la shubay, ciid duug ah ayaa dib loo warshadayn karaa oo dib loo isticmaali karaa, taas oo aad u yaraynaysa xoogga shaqada ee samaynta xudunta u ah samaynta, qaabaynta, ciiddu soo dhacayso, nadiifinta iyo isku xidhka kale. Way fududahay in la ogaado makaanaynta ama otomatiga.
4) Jajabka tirada badan ee resin ee ciidda waa 0.8% ~ 2.0% oo keliya, iyo qiimaha guud ee alaabta ceeriin waa yar yahay.
Sababtoo ah habka is-adkeysigu wuxuu leeyahay faa'iidooyin badan oo kor ku xusan oo gaar ah, habka is-adkeysigu looma isticmaalo oo keliya samaynta xudunta u ah, laakiin sidoo kale waxaa loo isticmaalaa dhejinta dhejinta. Waxay si gaar ah ugu habboon tahay hal qayb iyo wax-soo-saar yar yar, waxayna soo saari kartaa birta shubka ah, birta shubka ah iyo kuwa aan birta ahayn ee daawaha. Qaar ka mid ah aasaasayaasha Shiinaha ayaa si buuxda u beddelay caaryada ciidda engegan ee dhoobada ah, caaryada ciidda sibidhka, iyo qayb ahaan beddelay caaryada ciidda dhalada biyaha ah.
