Sidee loo nadiifin karaa caaryada garaafka?

Guud ahaan, marka habka qaabaynta la dhammeeyo, wasakh ama hadhaaga (iyadoo ay jiraan qaarka kooban kiimikoiyosifooyinka jireed) inta badan ayaa looga tagaacaaryada graphite. Noocyada kala duwan ee haraaga, shuruudaha nadiifinta kama dambaysta ah way ka duwan yihiin. Resins sida polyvinyl chloride wuxuu dhalin doonaa gaasta hydrogen chloride, kaas oo daxaleynaya noocyo badan oo birta caaryada garaafka ah. Hadhaaga kale ayaa laga soocay dab-demiska ololka iyo antioxidants, kuwaas oo sababi kara daxal ilaa birta. Waxa kale oo jira qaar ka mid ah midabada midabka leh oo soo saari kara birta, miridhku way adag tahay in la saaro. Xataa biyaha guud ee xiran, haddii lagu daayo dusha sare ee caaryada garaafka aan la daweyn muddo dheer, waxay sidoo kale dhaawac u geysan doontaa caaryada garaafka.

Sidaa darteed, caaryada graphite waa in la nadiifiyaa sida loo baahan yahay iyadoo loo eegayo wareegga wax soo saarka ee la aasaasay. Mar kasta oo caaryada garaafka laga soo saaro saxafada, daldaloolada caaryada garaafka waa in la furo si looga saaro dhammaan wasakhda oksaydhka leh iyo miridhku meelaha aan muhiimka ahayn ee caaryada graphite iyo template si looga hortago inay si tartiib tartiib ah u daxaliyaan dusha iyo geesaha. ee birta ah. Xaalado badan, xitaa ka dib nadiifinta, qaar ka mid ah caaryada garaafka aan la daboolin ama daxalaystay ayaa ugu dhakhsaha badan muujin doona calaamadaha miridhku mar kale. Sidaa darteed, xitaa haddii ay qaadato wakhti dheer in la dhaqo caaryada graphite ee aan la ilaalin, muuqaalka miridhku si buuxda looma ilaalin karo.

Guud ahaan, marka la isticmaalayo balaastiig adag, kuul quraarad ah, qolof walnut iyo pellets aluminium sida abrasives loogu talagalay shiidi-cadaadiska sare leh iyo nadiifinta dusha ee caaryada graphite, haddii kuwan abrasives loo isticmaalo si joogto ah ama si khaldan, habkan shiidi doonaa sidoo kale dhibaato. Porosity waxay ku dhacdaa dusha sare ee caaryada garaafka, hadhaagana waa sahlan tahay in loo hoggaansamo, taas oo keeneysa hadhaaga badan iyo xirashada, taas oo keeni karta dildilaac degdeg ah ama biligleynaya caaryada garaafka, taas oo aan u fiicnayn nadiifinta caaryada graphite.

Hadda, noocyo badan oo garaafyo ah ayaa lagu qalabeeyaa tuubooyinka "is-nadiifinta", kuwaas oo leh dhalaal sare. Ka dib markii la nadiifiyo oo la nadiifiyo daloolka hawo-mareenka si loo gaaro heerka polishing ee SPI # A3, laga yaabee ka dib marka la shiido ama la shiido, hadhaaga waxaa lagu sii daayaa aagga qashinka ee tuubada hawo-mareenka si looga hortago in hadhaaga u hoggaansamo dusha sare ee duubka qallafsan. istaag . Si kastaba ha ahaatee, haddii hawlwadeenku doorto suufka lagu dhaqo, maro emery, warqad ciid ah, dhagxaan wax lagu shiidi karo, ama burush leh naylon bristles, naxaas ama bir si uu gacanta ugu shiido caaryada garaafka, waxay keeni doontaa "nadiifin" xad dhaaf ah oo ah caaryada garaafka. .

Sidaa darteed, ka dib markii la raadiyo qalabka nadiifinta ee ku habboon caaryada graphite iyo farsamooyinka farsamaynta, iyo tixraaca hababka nadiifinta iyo wareegyada nadiifinta ee lagu duubay faylasha kaydka, in ka badan 50% wakhtiga dayactirka waa la badbaadin karaa, iyo xirashada caaryada garaafka si wax ku ool ah loo dhimo.
