Pazopanga zamagetsi, kulondola kwapang'onopang'ono kwa matabwa osindikizidwa (PCBS) kumagwirizana mwachindunji ndi magwiridwe antchito ndi mtundu wazinthu zamagetsi. Monga zida pachimake pobowola, bata ntchito ndi processing kulondola kwa PCB pobowola zida ndizofunikira kwambiri. Pakati pawo, chinthu chomwe nthawi zambiri chimanyalanyazidwa koma chofunikira kwambiri - maziko a granite - ndikuwunika mwakachetechete ngati kuthekera kwa zidazo kungapitirire.
Makhalidwe abwino a maziko a granite
Kukhazikika kwapadera, kugonjetsedwa ndi kusokonezeka kwa vibration
Pa PCB pobowola ndondomeko, pobowola pokha atembenuza pa liwiro lalikulu kudula bolodi, kupanga kugwedera mosalekeza ndi zovuta. Maziko a miyala ya granite, omwe ali ndi mawonekedwe owundana komanso ofananirako opangidwa ndi ma geological process kwazaka mazana a mamiliyoni, ali ndi zivomezi zamphamvu kwambiri. Granite yapamwamba kwambiri yomwe imayimiridwa ndi "Jinan Green" imakhala yolimba ndipo imatha kuyamwa bwino ndikumwaza mphamvu yogwedezeka yopangidwa ndi zida, ndikuwonetsetsa kukhazikika kwa zida zobowola pakugwira ntchito. Poyerekeza ndi zapansi zina zakuthupi, lubwe akhoza kwambiri kuchepetsa zotsatira za kugwedera pa malo olondola a pobowola pang'ono, kupanga malo olondola a mabowo mokhomerera apamwamba ndi kupatuka ankalamulira mu osiyanasiyana ang'onoang'ono, kukwaniritsa mkulu-mwatsatanetsatane pobowola zofunika ya yaying'ono-mabowo ndi diameters dzenje yaing'ono kwa matabwa mkulu-osalimba PCB.
Kuuma kwakukulu ndi kukana kuvala kumatsimikizira kulondola kwa nthawi yayitali
Kuchita kubowola pafupipafupi kumabweretsa vuto lalikulu pakukaniza kwapansi kwapansi. Kulimba kwa Mohs kwa granite kumatha kufika 6 mpaka 7, kupitilira zitsulo wamba komanso mapulasitiki ambiri auinjiniya. Makhalidwe olimba kwambiriwa amathandizira kuti maziko a granite akhalebe osalala komanso osalala pamwamba pake ngakhale atakumana ndi mphamvu komanso kukangana kwa pobowola kwa nthawi yayitali. Ngakhale pambuyo pa ntchito zambiri zobowola, kuchuluka kwa kuvala kumakhala kosasamala, motero kuonetsetsa kuti zipangizo zobowola zimakhala zokhazikika kwa nthawi yayitali komanso kulondola kosasinthasintha. Izi ndizofunikira kwambiri pamabizinesi akuluakulu opanga ma PCB. Ikhoza kuchepetsa nthawi yochepetsera zida ndi nthawi yokonza chifukwa cha kuvala kwapansi, kupititsa patsogolo kupanga komanso kuchepetsa mtengo wonse wopanga.
Kukula kwamafuta otsika ndi kutsika, kutengera kusintha kwa kutentha
M'malo opangira ma PCB, kutentha kozungulira kumasinthasintha chifukwa cha zinthu monga nyengo ndi kutentha kwa zida. M'munsi opangidwa ndi zipangizo wamba ali ndi zoonekeratu matenthedwe kukulitsa ndi chidule zochitika, zomwe zingachititse kusintha kwa malo wachibale wa zida zigawo zikuluzikulu ndipo potero zimakhudza kulondola pobowola. Granite ili ndi coefficient yotsika kwambiri pakukulitsa kutentha. Mwachitsanzo, mzere wokulirapo wa granite wamba ndi pafupifupi 4.6×10⁻⁶/℃. Kutentha kukasintha, kukula kwa maziko a granite kumakhalabe kosasintha, kumapereka maziko okhazikika komanso odalirika othandizira zida zobowola. Kaya m'chilimwe chotentha kapena m'nyengo yozizira, zidazo zimatha kukhala ndi malo obowola bwino kwambiri, kuwonetsetsa kuti kusasinthasintha kwa kubowola kwamagulu osiyanasiyana azinthu za PCB.
Sinthani limagwirira wa zida pobowola PCB
Kuyika bwino ndikuyika maziko kumayala maziko olondola
Panthawi yokonza maziko a granite, kupyolera mwa njira zamakono zodulira diamondi ndikupera, kutsika kwakukulu kwambiri ndi kulondola kwazithunzi zingatheke. Mwachitsanzo, kulolerana kwa flatness kwa maziko olondola kwambiri a granite mkati mwa 1m × 1m kumatha kuwongoleredwa osapitilira 4μm. Izi zimathandiza kuti zida zobowola zikhazikike mwachangu komanso molondola potengera ndege yeniyeni komanso mawonekedwe oyika maziko, ndikupatuka kochepa kwa gawo lililonse. Kuyika kolondola ndi kuyika kwake kumapereka chitsimikizo cha kayendetsedwe kabwino ka kubowola panthawi yogwiritsira ntchito zida, kuwongolera kulondola kwa kubowola kuchokera kugwero ndikuchepetsa bwino mavuto monga kupatuka kwa dzenje ndi ma diameter osagwirizana a dzenje omwe amayamba chifukwa cha kuyika kwa zida zosayenera.
Limbikitsani kusasunthika kwa kamangidwe ndikuwongolera magwiridwe antchito
Pamene PCB pobowola zida zikugwira ntchito, kuwonjezera kugwedezeka kwake, zikhoza kukhudzidwa ndi mayendedwe akunja, osagwirizana workshop pansi ndi zinthu zina. Maziko a granite ali ndi kachulukidwe kwambiri komanso kulimba kolimba. Pambuyo pophatikizidwa kwambiri ndi mapangidwe akuluakulu a zipangizo, zimatha kupititsa patsogolo kukhazikika kwapangidwe kwa zipangizo zonse. Zida zikagwiritsidwa ntchito ndi mphamvu yakunja kapena kugwedezeka, maziko a granite amatha kugawanitsa mphamvu zowonongeka ndi kukhazikika kwake kwamphamvu, kulepheretsa zigawo zikuluzikulu za zipangizozo kuti zisasunthike kapena ziwonongeke chifukwa cha mphamvu yosagwirizana, ndikuwonetsetsa kuti zidazo zikugwira ntchito mokhazikika pansi pa zovuta zogwirira ntchito. Dziko logwira ntchito lokhazikika limathandizira kukulitsa moyo wautumiki wa zidazo ndipo limapereka malo okhazikika komanso odalirika ogwirira ntchito pakubowola kwapamwamba panthawi yomweyo.
Zotsatira zenizeni zopanga
Kupanga kwa PCB kwa zinthu zamagetsi zamagetsi
Popanga PCBS pazinthu zamagetsi zamagetsi monga mafoni anzeru ndi makompyuta apakompyuta, chofunikira pakubowola molondola ndichokwera kwambiri. Kampani yodziwika bwino yopanga zamagetsi itayambitsa zida zoboola za PCB zokhala ndi maziko a granite, zokolola zidakwera kuchokera pa 80% yoyambirira kufika kupitirira 90%. Mavuto monga kugwirizana kwa mzere wosauka komanso dera lalifupi lomwe limabwera chifukwa cha kusakwanira koboola bwino kwachepetsedwa kwambiri. Pakadali pano, chifukwa cha maziko a granite kuchepetsa kuchuluka kwa kukonza zida, mphamvu yopangira mwezi uliwonse ya bizinesiyi yakula ndi 20%, kutsitsa mtengo wopangira pamtengo uliwonse ndikupambana mtengo ndi mwayi wabwino pamsika wowopsa wamsika.
Kupanga mafakitale oyang'anira board PCBS
Malo ogwirira ntchito a matabwa olamulira mafakitale ndi ovuta, ndipo zofunikira zodalirika za PCBS ndizokhwima. Kampani yomwe imagwira ntchito yopanga ma board owongolera mafakitale yawona kuwonjezeka kwakukulu kwa chiwongolero cha ma board ake a PCB pamayeso ovuta a zachilengedwe monga kutentha kwambiri komanso chinyezi chambiri atatengera zida zoboola zokhala ndi maziko a granite. Kukhazikika kwapang'onopang'ono kwa zida kumapangitsa kuti khalidwe la kubowola likhale lodalirika, kupereka chitsimikizo chokhazikika cha kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka mafakitale. Pokhala ndi zinthu zapamwamba kwambiri, bizinesiyo yatsegula bwino misika yamakasitomala apamwamba kwambiri, ndipo kukula kwake kwabizinesi kukukulirakulirabe.
Maziko a granite, ndi kukhazikika kwawo kwakukulu, kuuma kwakukulu ndi kukana kuvala, komanso kuwonjezereka kwa kutentha ndi kutsika kochepa, zimagwira ntchito yosasinthika popititsa patsogolo mphamvu ya zida zobowola za PCB. Kuchokera pakuyika ndikuyika bwino mpaka kukulitsa kukhazikika kwa zida, komanso magwiridwe ake apamwamba pamapangidwe osiyanasiyana enieni, onse awonetsa kufunika kwake pakuwongolera kubowola molondola komanso kupanga bwino kwa PCBS. Panjira yotsata kulondola kwambiri komanso kuchita bwino pakupanga kwa PCB, maziko a granite mosakayikira ndiye chinsinsi chotsegulira kuthekera kwakukulu kwa zida zobowola za PCB, ndipo amayenera kuyang'aniridwa ndikugwiritsa ntchito kuchuluka kwamakampani opanga zamagetsi.
