Amaqonga okulinganisa igranite asisiseko se-metrology echanekileyo kakhulu. Nokuba ixhasa umatshini wokulinganisa odibeneyo (CMM), i-laser interferometer, okanye isebenza njengomphezulu wesalathiso sokuhlolwa kwe-optical, la maqonga abonelela ngozinzo lobushushu olungenakuthelekiswa nanto kunye nokunciphisa ukungcangcazela. Sekunjalo, kwanegranite emnyama ye-ZHHIMG® ekumgangatho ophezulu (ubuninzi obuyi-≈3100 kg/m³) ifuna ukulungiswa okucwangcisiweyo ukuze kulondolozwe ukuchaneka kwayo kwinqanaba le-nanometer kwiminyaka emininzi yenkonzo. Ukungakhathali akuyongozi nje kuphela kwilitye - yingozi kwinkqubo yakho yonke yomgangatho.
Ukucoca yindlela yokuqala yokuzikhusela, kodwa kudla ngokwenziwa gwenxa. Eyona mpazamo ixhaphakileyo esiyibonayo kuhlolo lwentsimi kukusetyenziswa kwezicoci ezingafanelekanga. Izicoci zeglasi ezisekelwe kwi-ammonia, izicoci ze-acidic, okanye ii-abrasive pads zinokuqhekeza umphezulu okanye zishiye iintsalela ezitshintsha ukufundwa komlinganiselo. Indlela echanekileyo ilula: sebenzisa ilaphu elingena-lint elimanziswe nge-50/50 isopropyl alcohol namanzi. Sula kancinci kwicala elinye, uze womise ngoko nangoko ngelaphu elicocekileyo nelomileyo. Ungaze uvumele ulwelo ludibane phezu komphezulu. Kwioyile okanye ulwelo olusikiweyo, isicoci selitye esikhuselekileyo siyamkeleka - kodwa soloko ulandela ngesicoci se-alcohol ukususa nayiphi na intsalela ye-surfactant. Kwaye khumbula:amaqonga egraniteazifuni ioyile okanye umhlwa wokuthintela. Ngokungafaniyo nentsimbi ephoswe ngesinyithi, azidli mhlwa. Ukusebenzisa ioyile kudala kuphela ifilimu etsala uthuli kwaye inciphise imilinganiselo yoqhagamshelwano.
Ulawulo lokusingqongileyo lubalulekile njengokucoca. I-Granite's thermal expansion coefficient ephantsi (malunga ne-1/3 yentsimbi ephoswe) iyenza izinze ngokumangalisayo, kodwa ayikhuselekanga. Ubushushu obuphezulu kumphezulu weqonga — obubangelwa kukukhanya kwelanga ngqo, ii-HVAC vents, okanye imithombo yobushushu ekufutshane — bunokubangela ukwanda kwendawo efana neempazamo zokuthamba. Sicebisa ukugcina iindawo zelebhu kwi-20±2°C kunye nomswakama ophakathi kwe-40–60%. Kuphephe ukubeka iiplatifomu kufutshane neefestile, ii-radiator, okanye izitishi zokuwelda. Ukuba indawo yakho ayinalo ulawulo lobushushu, cinga ngokugquma ngaphantsi kweqonga nasemacaleni ukuze likhuseleke kwi-ambient swings.
Inkxaso kunye nokuphathwa kwazo kubaluleke ngokulinganayo. I-granite inamandla ekucinezeleni kodwa isengozini yokuthwala imithwalo kunye nefuthe. Sebenzisa rhoqo iindawo zokuxhasa ezichaziweyo zomenzi — ngesiqhelo zibe zintathu kumaqonga aqhelekileyo, okanye iindawo ezininzi kwiziseko ezinkulu ngokwesikhokelo se-GGG-P-463C. Inkxaso eqinileyo enamachaphaza amane inokubangela uxinzelelo kwaye igobe umphezulu ngokuhamba kwexesha. Xa ususa okanye ufaka izinto zokusebenza, phakamisa — ungaze utyibilike. Inxalenye yentsimbi ewileyo inokusika umphetho okanye idale ukuxinana kwendawo okungekho mfuneko yokucoca. Iilappers zethu eziphambili, ezininzi ezinamava angaphezu kweminyaka engama-30, zihlala zifumanisa ukungaqheleki komphezulu we-sub-micron ngokuchukumisa kuphela. Phatha iqonga ngentlonipho efanayo obungayinika umphezulu ocacileyo.
Ukugcinwa kunye nokukhuselwa ngexesha lokungasebenzisi kudla ngokunganakwa. Xa iqonga lingalingani, ligqume ngesigqubuthelo sothuli esiphefumlayo, esingenalo uthuli. Kuphephe ukugqunywa ngeplastiki, enokubamba umswakama kwaye ikhuthaze ukudaya. Ukugcina ixesha elide, faka umaleko omncinci weoyile yesixhobo kuphela kwizinto ezifakwe kwi-granite okanye izinto ezifakwe kwi-granite - ungalokothi uye kumphezulu we-granite ngokwawo. Gcina kwindawo ecocekileyo, neyomileyo enobushushu obuzinzileyo.
Ukulinganisa yintsika yokugqibela yokugcinwa. Nokuba kunyanyekelwa ngokugqibeleleyo, zonke iinkqubo zokulinganisa zihamba ngokuhamba kwexesha. Sicebisa ukuqinisekiswa kokuthamba rhoqo emva kweenyanga ezi-6-12, kuxhomekeke kubungakanani bokusetyenziswa kunye nokuzinza kokusingqongileyo. Emva kokufuduswa, ukuchaphazeleka, okanye ukugaya kwakhona, ukulinganisa kwakhona kuyimfuneko. Kwi-ZHHIMG®, yonke iqonga lithunyelwa neesatifikethi zokulinganisa ezinokulandelelwa kwi-metrology institutes zesizwe (Jinan/Shandong Provincial Metrology Institutes, ezinokulandelelwa kwi-NIM). Kubathengi abafuna ukuqinisekiswa komntu wesithathu, sinikezela ngeenkonzo zokulinganisa ze-ISO 17025 ezivunyiweyo yi-UKAS/ANAB. Olu xwebhu alupheleli nje ekuthobeleni imithetho - luqinisekiso lwakho lokuba iqonga lisahlangabezana neemfuno zalo zokuqala.
Enye ingcamango ephosakeleyo esihlala sidibana nayo kukuba "ukugcinwa" kuthetha "ukulungiswa." Akunjalo. Ukugcinwa kuyasebenza. Kukucinywa kwemihla ngemihla, ukubekwa ngononophelo kweendawo, ukujonga okusingqongileyo, kunye nokulinganiswa okucwangcisiweyo. Ukulungiswa kuyasebenza - kwaye kwi-metrology echanekileyo, ukusabela kuyakhawuleza. Umphetho oqhekekileyo okanye i-V-groove egugileyo ngamanye amaxesha inokuphinda idityaniswe ziingcali ezinobuchule, kodwa umonakalo omkhulu unokufuna ukutshintshwa. Ukuthintela kusoloko kungabizi kakhulu kunokulungiswa.
Kubathengi behlabathi kunye nabaphathi belebhu, umyalezo ucacile: amaqonga egranite lutyalo-mali ekuqinisekiseni ukulinganisa. Khusela olo tyalo-mali ngolondolozo olucwangcisiweyo nolunolwazi. Ukuba awuqinisekanga malunga neendlela osebenza ngazo ngoku, cela umthengisi wakho ukuba akunike uluhlu lokujonga ulondolozo okanye uvavanyo lwendawo. Kwi-ZHHIMG®, sinikezela ngezikhokelo zokhathalelo oluneenkcukacha ngokuthunyelwa ngakunye — kuba sikholelwa ukuba ukuchaneka akupheli ekuhanjisweni. Kuyaqhubeka ngokuchukumisa ngakunye ngononophelo, ukusula ngakunye okufanelekileyo, kunye nokulinganisa ngakunye ngexesha elifanelekileyo.
Ngaba ufuna iprotokholi yokulungisa eyenzelwe wena izinto zakho ezithile zegranite? Nxibelelana neqela lethu lenkxaso ye-metrology. Siza kulungelelanisa iingcebiso ngokusekelwe kubungakanani beqonga lakho, indawo yokusetyenziswa, kunye neshedyuli yokulinganisa — kuba ukuchaneka kwexesha elide akuyongozi. Yenziwe ngobuchule.
