Ingxaki yokucoca i-fasteners yamandla aphezulu idla ngokubonakaliswa emva kokunyanga ukushisa kunye nokufudumala, kwaye ingxaki enkulu kukuba ukuhlanjululwa akucocekanga. Njengomphumela wokupakishwa ngokungekho ngqiqweni kweziqhoboshi, ilyethi ihlala phezu komhlaba, yenze umhlwa ongaphezulu kunye nokutsha kwealkali, okanye ukukhetha okungafanelekanga kwe-oyile yokucima kwenza umhlwa womphezulu we-fastener.
1. Ungcoliseko oluveliswa ngexesha lokuhlanjululwa
Emva kokucima, i-fasteners yahlanjululwa nge-agent ye-silicate yokucoca kwaye ihlanjululwe. Izinto eziqinileyo zavela phezulu. Izinto eziphathekayo zihlalutywe nge-spectrometer ye-infrared kwaye ziqinisekiswe ukuba ziyi-silicate ye-inorganic kunye ne-iron oxide. Oku kubangelwa intsalela ye-silicate kwi-fastener surface emva kokuhlamba okungaphelelanga.
2. Ukupakishwa kweefasteners akukho ngqiqweni
Emva kokuba i-fasteners epholileyo ibonisa iimpawu zokuguquka kombala, gcoba nge-ether, vumela i-ether iguquke kwaye ifumane intsalela enamafutha, izinto ezinjalo zinomxholo ophezulu we-lipids. Ibonisa ukuba i-fasteners ingcolisekile ngama-agent okucoca kunye namafutha okucima ngexesha lokuhlanjululwa, elinyibilikayo kwiqondo lokushisa lokushisa kwaye lishiye imichiza evuthayo. Izinto ezinjalo zingqina ukuba umphezulu we-fastener awucocekanga. Ukuhlalutywa nge-spectrometer ye-infrared, ngumxube we-oyile yesiseko kunye ne-ether kwi-oyile yokucima. I-ether inokuvela ekongezwa kweoli yokucima. Iziphumo zokuhlalutya kweoli yokucima kwi-mesh belt furnace ziqinisekisa ukuba i-fasteners ine-oxidation encinci kwi-oyile yokucima ngenxa yokupakisha okungekho ngqiqweni ngexesha lokufudumeza, kodwa iphantse ibe yinto engafanelekanga. Le nto inxulumene nenkqubo yokucoca, kunokuba ingxaki yeoli yokucima.
3. Intsalela yomphezulu
Intsalela emhlophe kwisikrufu samandla aphezulu yahlalutywa nge-infrared spectrometer kwaye yaqinisekiswa ukuba yiphosphide. Akukho arhente yokucoca i-asidi esetyenzisiweyo ukucoca itanki yokuhlamba, kwaye ukuhlolwa kwetanki ye-rinse kufumanise ukuba itanki ine-carbon solubility ephezulu. Itanki kufuneka ichithwe rhoqo, kwaye inqanaba lokuxinana kwelye kwitanki yokuhlamba kufuneka lihlolwe rhoqo.
4. Ukutsha kwealkali
Amandla aphezulu Screw ukucima intsalela ubushushu blackening has a uniform, ioli egudileyo emnyama umphandle. Kodwa kwindandatho yangaphandle kukho indawo ebonakalayo ye-orange. Ukongezelela, kukho iindawo eziluhlaza okwesibhakabhaka okanye ezibomvu ezikhanyayo.
Kufunyenwe ukuba indawo ebomvu kwi-screw ibangelwa ukutshiswa kwe-alkali. I-agent yokucoca i-alkaline equkethe i-chlorides kunye ne-calcium compounds iya kutshisa izibophelelo zetsimbi ngexesha lokunyanga ukushisa, ukushiya amabala ebusweni be-fasteners.
I-alkalinity ye-alkalinity ye-steel fasteners ayikwazi ukususwa kwioli yokucima, ukwenzela ukuba umphezulu utshise kwiqondo lokushisa eliphezulu i-austenite kwaye ikhulise ukulimala kwisinyathelo esilandelayo sokufudumala. Kunconywa ukuba uhlambe kwaye uhlanjululwe i-fasteners ngokucokisekileyo ngaphambi konyango lokufudumala ukususa ngokupheleleyo iintsalela ze-alkaline ezibangela ukutshisa kwi-fasteners.
5. Ukuhlamba ngokungafanelekanga
Kwizinto zokuqinisa ubungakanani obukhulu, i-polymer aqueous solution quenching ihlala isetyenziswa. Ngaphambi kokucima, i-ejenti yokucoca i-alkali isetyenziselwa ukucoca kunye nokuhlanjululwa kwe-fasteners. Emva kokucima, i-fasteners iye yagqwala ngaphakathi. Uhlalutyo kunye ne-infrared spectrometers luqinisekisile ukuba ngaphezu kwe-iron oxide, kukho i-sodium, i-potassium kunye ne-sulfure, ebonisa ukuba i-fastener inamathele ngaphakathi kwe-agent yokucoca i-alkali, mhlawumbi i-potassium hydroxide, i-sodium carbonate okanye izinto ezifanayo, zikhuthaza ukugqwala. I-Fastener rising ijongwa ukuba ingcoliseke ngokugqithisileyo kwaye ukutshintshwa rhoqo kwamanzi okuhlanjululwa kwakhona kuyacetyiswa. Ukongezelela, ukongeza i-rust inhibitor emanzini nayo yindlela efanelekileyo.
