Njengenxalenye yomsebenzi phantse zonke iintlobo zezixhobo zedayimani (ngaphandle kwezixhobo zedayimani eziye zasebenzisa itungsten carbides okanye iiPCDs, ezinjengezando zasehlathini, izixhobo zokususa i-PCD), amacandelo edayimani abalulekile.Ngokubanzi, kukho iintlobo ezi-2 zezahlulo zedayimani: intsimbi eboshiweyo kunye ne-resin-bond.
Izahlulo zedayimani eziboshwe ngetsimbi zisetyenziswa ngokubanzi kuzo zonke iintlobo zezixhobo zedayimani, kuqukaiincakuba zedayimani, amavili ekomityi yokusila idayimani, diamond core drill bit, njl. Nangona amacandelo e-diamond e-resin-bonding ahlala esetyenziselwa kuphela kwizixhobo zokugaya idayimane ezifana ne-diamond polishing pads, i-resin concrete grinding pads, njl.
Kodwa ngaba wakha wazibuza ukuba yintoni eyenza icandelo ledayimani eliboshwe ngesinyithi?
Impendulo ithiAmacandelo eDayimanekwayeMetal Powder.Inxalenye yedayimani edibeneyo yesinyithi ngumxube we-diamond particles kunye nee powders zetsimbi emva koxinzelelo olubandayo kunye noxinzelelo olushushu.Masifunde ngakumbi malunga “nedayimani” kunye “neMetal Powder”.
“Iidayimani ezenziweyo”
"Iidayimani" zinokwahlulwa zibe yiidayimani zendalo kunye needayimani ezenziweyo.
Iidayimani zendalo zenziwe kwiimilo ezahlukeneyo njengezacholo ezibizayo, ngelixa iidayimani ezenziweyo zisetyenziswa kakhulu kwiintlobo ngeentlobo zezixhobo zedayimani.
Njengenye yezinto ezibalulekileyo zamacandelo edayimane (enye ingumgubo wesinyithi), idayimani eyenziweyo isebenze njengenxalenye yomsebenzi kwaye ingasetyenziselwa ukusika, ukugaya kunye nokugrumba izinto ezahlukeneyo zokwakha ezifana nekhonkrithi, i-asphalt, i-tile, iglasi, igranite, ibhastile, namanye amatye.
Amasuntswana edayimani eyenziweyo aneengongoma ezi-3 eziphambili: iiMilo, amaBanga kunye neeGrits.
(Amasuntswana edayimani alandelayo abhekisa “kumasuntswana edayimani eyenziweyo”)
1.1 Iimilo ezahlukeneyo zamasuntswana edayimani
Amasuntswana edayimani anemilo eyahlukeneyo yezicelo ezahlukeneyo.Kukho ubukhulu becala iimilo ezi-2: enye luhlobo lweGranular, kwaye enye luhlobo lweFlethi.
Amasuntswana edayimani egranular asetyenziswa ikakhulu ukusika kunye nokugrumba.Amasuntswana edayimani egranular alungile kufuneka abe yi-angular.Imiphetho kunye neekona ziqinisekisa ukusika kunye nokusebenza kokomba.
Amasuntswana edayimani acwebezelayo asetyenziswa ikakhulu ekusileni & ukupolisha.Kuba kwinkqubo yokusila & ukupolisha, injongo kukwenza ubuso obusebenzayo bube lula kwaye bugudileyo, kodwa ukuba usebenzisa amasuntswana edayimane egranular, kuya kushiya imikrwelo emikhulu ebusweni obusebenzayo.
1.2 Amabanga ahlukeneyo amasuntswana edayimani
Iidayimani zinamabakala ahlukeneyo osetyenziso olwahlukileyo.Ngokubanzi, amasuntswana edayimani asetyenziselwa ukusika kunye nokugrumba anomgangatho ophezulu kunawo asetyenziselwa ukucola.Ngenxa yokuba ukusika kunye nokugrumba kuneemfuno eziphezulu zamasuntswana edayimane kunokugaya.Umzekelo, umgangatho wamasuntswana edayimani kwincakuba yesarha yedayimani uphezulu kunomgangatho wezixhobo zokusila idayimani.
1.3 Iisayizi ezahlukeneyo zamasuntswana edayimani
Ubungakanani bamasuntswana esiwabize ngokuba yi "diamond grit".Okukhona lilikhulu inani lesuntswana ledayimani, kokukhona lincinane amasuntswana edayimani.Ubungakanani bamasuntswana edayimani kunye nenombolo yayo yegrit yedayimani ihambelana ngokuphambeneyo.Ubungakanani obukhulu bamasuntswana edayimani aqhele ukusetyenziselwa ukusika, ukugawula ngokurhabaxa, kunye nokugrumba.Ubungakanani obuphakathi bamasuntswana edayimani budla ngokusetyenziselwa ukusila okuphakathi.Ubungakanani obuncinci bedayimane ngokuqhelekileyo busetyenziselwa ukupolisha.Jonga le theyibhile ilandelayo ukwazi iigrits ezahlukeneyo zedayimani ezisetyenziswa kwizixhobo ezahlukeneyo zedayimani:
Ukuba ufuna ukwazi ngakumbi malunga nobungakanani besuntswana ledayimani kunye nenombolo yegrit yedayimane ehambelanayo, jonga i "Diamond Particle Conversion Chart" njengoko ingezantsi.Amazwe okanye imibutho eyahlukeneyo isebenzisa imigangatho eyahlukeneyo, kodwa yahluke kancinane.Into endifuna ukuyithetha kukuba, inani legrit yedayimani lihlala liluhlu, njenge 35/40 #, 40/50 #.Ngamanye amaxesha siprinta inombolo enye yegiti nje ngo 40# kwiizixhobo zedayimaningokulula okanye ngenxa yeemfuno zabathengi.
Ngezixhobo zedayimani elangeni, siprinta kuphela amanani ebhanti yedayimani kwizixhobo zethu zokusila idayimani.

I "Metal Powder"
I-powder yensimbi isetyenziswe njenge-arhente yokubambisana, oku kuthetha ukuba iya kudliwa ngokuthe ngcembe kwaye incede ukuveza amaqhekeza edayimane ngexesha lokusebenza.Ingumxube weentsimbi ezahlukeneyo ezifana neCu, Sn, Ag, Co, Ni, WC, Mo, njl.Nceda ujonge ngolu hlobo lulandelayo:
• I-Fe – Umgubo we-ayini unexabiso eliphantsi kwaye yeyona nto iphambili yomgubo wentsimbi.
• I-Cu - Umgubo wobhedu usebenza njengento yokuncamathelisa, ngamanye amaxesha yeyona nto iphambili yomgubo wesinyithi (njengamacandelo edayimani yebhastile, njl.njl.)
• Ni- I-powder ye-nickel isetyenziselwa ukuphucula ukuqina kwecandelo ledayimani kunye nokwenza ukuba isahlulo sedayimani sibe nzima ukuphulwa, kunye nokwandisa amandla entsimbi yentsimbi.
• I-Cobalt powder ine-high-temperature resistance, kwaye isetyenziselwa ukuphucula ukuzinza kwe-thermal yensimbi, ngokuqhelekileyo isetyenziselwa izixhobo zokusika idayimane ezomileyo kunye nezixhobo zokugaya idayimane ezomileyo.
• (Sn)Tin kunye ne (Zn)zinc powder zinendawo esezantsi yokunyibilika kwaye zidlala indima yokuhlangana.
Ifomula yeCandelo leDayimane (okanye iFomula yeDayimane)
Ifomula yecandelo ledayimani ikwabizwa ngokuba yifomula yedayimane.Iza ngamasuntswana edayimani kunye nezinto ezithile zetsimbi ezinomlinganiselo othile.Iifomula ezahlukeneyo zedayimani zisetyenziselwa izicelo ezahlukeneyo.Ziphuhliswa ikakhulu zizinto ezi-4:
1. Uhlobo lwezinto eziphathekayo oluza kunqunyulwa, luphantsi kwaye luqhutywe
Iindidi ezahlukeneyo zezixhobo zidinga iifomyula ezahlukeneyo zedayimane, ezifana negranite, imarble, ikhonkrithi, i-asphalt, njl.
2. Amabanga asemgangathweni.
Umgangatho ophezulu wamacandelo edayimani uthetha ixabiso eliphezulu.Iimarike ezahlukeneyo zamkela amaxabiso ahlukeneyo, ngoko umgangatho ohlukeneyo wamacandelo edayimani wenziwa kwiimarike ezahlukeneyo.
3. Ukusebenza okuphezulu kunye nexesha elide lokuphila, ukhetha eyiphi?
Siyazi ukuba izixhobo ezininzi diamond umenzi okanye ababoneleli bathi izixhobo zabo diamond ukusebenza eliphezulu kunye nobomi obude.Kodwa eneneni, asinakuba nobona bomi buphezulu kunye nobona bomi bubude ngaxeshanye.Kufuneka senze ukhetho.Ukuba ufuna ukusebenza okuphezulu, ezinye zexesha lokuphila ziya kufinyezwa.Ukuba ufuna ubomi obude, ngokufanayo, ukusebenza kuya kunikelwa.Nazi iindlela ezi-3 ezahlukeneyo onokukhetha kuzo:
- Ukusebenza okuphezulu kunye noBomi obuphantsi.
- Ukusebenza okuphantsi kunye noBomi obuPhakamileyo.
- Ukusebenza okuPhakathi kunye noBomi obuphakathi.
4. Iifomyula zecandelo ledayimane ezizodwa kubathengi abathile.
Njengomvelisi wecandelo ledayimani yobungcali ukususela ngo-1993, i-Sunny Tools sele iphuhlise iifomyula ezininzi zedayimani zezicelo ezahlukeneyo kunye neemarike.Siphuhlise icandelo ledayimani kwaye silivavanya kumatye kunye nekhonkrithi yemarike enkulu.Kodwa kukho amatye amaninzi ahlukeneyo kwihlabathi jikelele, ngoko ke ukulungelelanisa iifomyula zedayimani zeprojekthi ethile kuyimfuneko.
Nasi isisombululo sethu: Abathengi abatsha banokuthenga iiseti zamacandelo ethu edayimani ukuze avavanywe ekuqaleni.Ukuba abafikelelanga kulindelo lwakho, sinike ingxelo kwaye sinokuhlengahlengisa iifomula zedayimani ukuhlangabezana neemfuno zakho.
Ngaphezu koko, u-Sunny uya kuthiya iifomyula zedayimane ezikhethekileyo ezineekhowudi ezahlukeneyo kwaye uqaphele ukusebenza kwazo.Ngaloo ndlela, unokukhetha nje amanani athile ekhowudi kwaye unxibelelwano lulula kwaye lusebenza kakuhle.
Ukuqukumbela, kukho iifomula ezininzi ezahlukeneyo zedayimani ekufuneka ziphuhliswe.Ngokubala ngokurhabaxa, ndenze itheyibhile yeentlobo ezingama-81 zeefomula zedayimane, kodwa zingaphezulu koku.Izizathu zezi:
- 1. inkampani inokuphuhlisa ngaphezu kwamabakala ama-3 kumacandelo edayimani.
- 2. kukho iifomyula ezininzi zedayimani zezixhobo zokusila eziphathekayo - ezininzi iigrits zedayimane kunye neentlobo zebhondi kufuneka zibalwe.
- 3. iifomula zedayimani ezinentsebenzo eyahlukeneyo kunye nexesha lokuphila azikhange ziqwalaselwe.
- 4. iifomula zedayimani ezizodwa kubathengi abathile azikhange ziqwalaselwe.
Itshathi ilandelayo - "Iifomula zedayimane zeZimathiriyeli ezahlukeneyo" kukukunika ingcinga erhabaxa yobungakanani beefomyula zecandelo ledayimani.
Kumanqaku alandelayo, siya kuqhubeka sithetha malunga:
1. Iindidi ezahlukeneyo zamacandelo edayimani
2. Ukuveliswa kwamacandelo edayimani
3. Uhlobo lwe-welding yamacandelo edayimani
