Kwa ma lab omwe amagwira ntchito motsatira malamulo okhwima okhudza kukonza zinthu, chitsulo chopangidwa ndi chitsulo chingakhale chisankho chabwino. Koma pa ntchito yamakono yoyezera zinthu yomwe ikukankhira ku milingo ya micro-inch ndi sub-micron, zoletsa zimakhala zovuta kuzinyalanyaza—ndipo ndalama zobisika zogwirira ntchito bwino zimayamba kupitirira phindu loyamba la mtengo.
Kumene Granite Imasintha Kukambirana
Ma granite achilengedwe pamwamba pake adapezeka ngati njira ina yabwino kwambiri, ndipo pakapita nthawi akhala chisankho chokhazikika pakugwiritsa ntchito molondola kwambiri. Zifukwa zake sizovuta, koma ndizofunikira kuzimvetsa.
Kapangidwe ka kristalo ka granite kamapatsa ubwino wake weniweni wakuti chitsulo chopangidwa ndi makina sichingathe kubwerezabwereza nthawi zonse. Tinthu ta mchere tomwe timalumikizana timapanga chinthu chomwe chimakhala chosagwira ntchito bwino m'malo abwinobwino a labotale. Sichichita dzimbiri. Sichichita dzimbiri. Sichichita ndi mafuta ndi zosungunulira zomwe zimafika pamalo a labotale.
Kachitidwe ka kutentha kwa granite kamafunika chisamaliro chapadera. Pamene kutentha kwa labu yanu kumasintha pakati pa m'mawa ndi masana, kapena pamene nyengo ikusinthasintha malinga ndi nyengo, chitsulo chopangidwa chimakula ndikuchepa pang'ono. Kuchuluka kwa kutentha kwa granite kuli pafupifupi theka la chitsulo chopangidwa. Pa ntchito yomwe imafuna kulondola kwa mainchesi ang'onoang'ono, kusiyana kumeneku kumatanthauza kusatsimikizika kwa muyeso komwe simungakwanitse.
Granite imakhalanso ndi mphamvu zachilengedwe zochepetsera chinyezi zomwe zimathandiza kusiyanitsa miyeso yanu ndi kugwedezeka kwa chilengedwe. M'ma laboratories omwe ali pafupi ndi pansi popanga zinthu, zida zolemera, kapena m'makonde odzaza anthu, khalidweli limachepetsa "phokoso" lomwe lingasokoneze miyeso yovuta.
Kukhazikika kwa miyala ya granite kwa nthawi yayitali n'kodabwitsa kwambiri. Ndi chithandizo choyenera komanso chisamaliro choyenera, miyala ya granite yapamwamba imasunga kulondola kwake m'mibadwo yonse yomwe imagwiritsidwa ntchito. Ma laboratories ambiri apadziko lonse lapansi a metrology amatchulabe zinthu zakale za granite zomwe zakhala zikugwira ntchito kwa zaka makumi anayi kapena makumi asanu.
Kuyerekeza Mafotokozedwe Ofunika
Kuyang'ana manambala kumathandiza kuti zokambiranazo zikhale zenizeni osati malingaliro.
Kusunga kosalala pakapita nthawi kumathandizira kwambiri granite. Ma plate achitsulo chopangidwa ndi chitsulo amafunika kukonzedwanso nthawi ndi nthawi kuti abwezeretse kusalala koyamba—nthawi zambiri zaka zitatu kapena zisanu zilizonse zikagwiritsidwa ntchito, kutengera ntchito yomwe ikuchitika. Ma plate a granite ofanana ndi grade amasunga mawonekedwe awo kwa nthawi yayitali, nthawi zambiri amafunika kuthandizidwa pokhapokha atatha zaka zambiri akugwira ntchito.
Ma coefficients okulitsa kutentha amawonetsa granite pafupifupi 5-7 × 10⁻⁶ pa digiri Celsius, pomwe chitsulo chopangidwa ndi chitsulo chimayenda 10-12 × 10⁻⁶. Mu labu yokhala ndi kutentha kwa 2°C tsiku lantchito, kusiyana kwa kusintha kwa magawo pakati pa zinthu ziwirizi kumakhala kofunikira pa kulekerera kwa sub-micron.
Kulimba ndi kukana kukalamba kumathandizanso granite. Kulimba kwa granite kwa Mohs kumaposa kwa chitsulo chopangidwa ndi chitsulo, zomwe zikutanthauza kuti pamwamba pake sipakukanda ndi kupindika chifukwa chogwiritsa ntchito mwachizolowezi. Izi zikutanthauza kuti imakhala nthawi yayitali yogwira ntchito komanso yolondola nthawi zonse pa nthawi yonse yogwira ntchitoyo.
Kufananiza Chosankha Chanu ndi Chowonadi cha Labu Yanu
Zinthu zoyenera zimadalira kwambiri zomwe labu yanu imachita komanso momwe imagwirira ntchito. Taganizirani izi:
Ngati labu yanu ikugwira ntchito yowunikira ndi bajeti yosatsimikizika yomwe ikuyandikira malire a zida zanu, granite iyenera kukhala chisankho chanu chokhazikika. Kukhazikika kwa kutentha komanso kukhazikika kwa nthawi yayitali kumathandizira mwachindunji kulondola ndi kutsata komwe makasitomala anu ndi mabungwe ovomerezeka amayembekezera.
Ngati labu yanu ikuthandizira kwambiri kuyang'anira kupanga ndi kulekerera kwa mainchesi imodzi kapena kucheperako, chitsulo chopangidwa chingagwire ntchito mokwanira—bola ngati mukufuna kuchisamalira bwino ndikuchikonza pafupipafupi.
Ngati malo anu akusintha kwambiri kutentha tsiku lonse, kapena ngati zinthu zachilengedwe zili zochepa, ubwino wa kutentha kwa granite umakhala wofunikira osati wopindulitsa chabe.
Ngati akatswiri anu amagwira ntchito ndi ma plate pafupipafupi ndipo njira zotsukira sizimakhala zachizolowezi, kukana dzimbiri kwa granite kumachotsa vuto lalikulu la kuyeza ndi kuwonongeka kwa ma plate.
Nanga bwanji za mavuto a bajeti?
Apa ndi pomwe zenizeni zenizeni zimalowa m'nkhani. Ma granite apamwamba pamwamba nthawi zambiri amakhala ndi mitengo yoyambirira yokwera kuposa zitsulo zofanana. Kwa ma laboratories omwe ali ndi bajeti yochepa, kusiyana kumeneku kungawoneke ngati kofunika kwambiri.
Komabe, ndalama zonse zomwe munthu amawononga nthawi zambiri zimanena zosiyana. Werengani ndalama zokonzera zinthu kwa zaka khumi: kukonzanso chitsulo chopangidwa ndi chitsulo, kukonza zinthu pafupipafupi, kuyeretsa, ndi ndalama zobisika zomwe zimabwera chifukwa cha nthawi yogwira ntchito pamene mbale sizikugwira ntchito. Ganizirani za chiopsezo cha zolakwika zoyezera kuchokera pamalo owonongeka kapena osakhazikika. Mukaphatikiza izi, nthawi zambiri anthu amakonda granite ngakhale kuti mtengo wake ndi wokwera.
Ogulitsa zida ambiri amapereka njira zopezera ndalama zomwe zimapangitsa kuti kusiyana kwa ndalama zomwe zilipo pasadakhale kuthe. Ma laboratories ena amapeza kuti kuwonetsa mtengo wonse wa umwini kwa oyang'anira kumapangitsa kuti nkhani yokhudza ndalama ikhale yomveka bwino kuposa kuyerekeza mitengo yogulira yokha.
Kupanga Kusintha
Ngati labu yanu ikugwiritsa ntchito mbale zachitsulo zotayidwa ndipo mukuganiza zosintha kukhala granite, yang'anani mosamala. Yambani poyesa momwe zida zanu zilili komanso nthawi yomwe zingagwiritsidwe ntchito. Kusintha mbale zomwe zili mkati mwa zofunikira sikungakhale kofunikira, ngakhale granite itakhala yabwino kwambiri.
Ngati pakufunika kusintha—kaya chifukwa cha kuwonongeka, kuwonongeka, kapena kufunikira kolondola kowonjezereka—ganizirani kusintha kukhala granite kuti mugwiritse ntchito pamalo anu ofunikira. Sungani chitsulo chosungunuka kuti mugwiritse ntchito zina pomwe kusiyana kwa magwiridwe antchito sikuli kofunikira kwenikweni.
Akatswiri anu angafunike kuphunzitsidwanso kwakanthawi pa momwe angagwiritsire ntchito ndi kusamalira. Granite imapirira kuwonongeka kuposa chitsulo chopangidwa ndi chitsulo, koma imatha kusweka chifukwa cha kugundana kwakukulu. Chithandizo choyenera ndi njira zogwirira ntchito zimakhalabe zofunika.
Mfundo Yofunika Kwambiri
Kwa ma laboratories amakono a metrology omwe amatsatira miyezo yolondola komanso yobwerezabwereza yokhala ndi bajeti yosadziwika bwino, miyala yachilengedwe ya granite pamwamba ndi chisankho choyenera kwambiri pazochitika zambiri. Ubwino waukadaulo ndi weniweni ndipo walembedwa bwino.
Komabe, chitsulo chopangidwa ndi chitsulo chikadali ndi malo ake m'ma laboratories okhala ndi zofunikira zochepa, bajeti yochepa, kapena njira zokonzera zinthu zomwe zimapangitsa kuti chitsulo chopangidwa ndi chitsulo chigwire ntchito bwino.
Chofunika kwambiri ndi kusankha zomwe mukufuna kuchokera ku zomwe mukufuna m'malo mongoganizira zomwe mukufuna, mtengo wokha, kapena malangizo a ogulitsa popanda kusanthula. Muyeso wanu ndi wabwino malinga ndi malo omwe amadalira.
Kodi mwakonzeka kufufuza njira zopangira granite molondola mu labotale yanu? Gulu lathu lili ndi luso lalikulu pothandiza ma labotale a metrology kusankha zida zoyenera kugwiritsa ntchito komanso bajeti yawo. Tikusangalala ndi mwayi wokambirana zomwe mukufuna ndikupangira mayankho omwe akugwirizana ndi vuto lanu.
Lumikizanani nafe kuti muyambe kukambirana za kukweza malo anu ofunikira.
