Sida Loo Doorto Walxaha Balaastigga ah ee ugu Wanaagsan ee Duritaan Caag ah
Doorashada caagga saxda ah ee qaabaynta cirbadeynta balaastikada ah waxay noqon kartaa mid adag - waxaa jira kumanaan ikhtiyaar oo suuqa ah oo laga dooran karo, kuwaas oo qaar badan oo ka mid ah aan u shaqeyn doonin yool la bixiyay. Nasiib wanaag, faham qoto dheer oo ku saabsan waxyaabaha la doonayo iyo codsiga loogu talagalay ayaa kaa caawin doona in la yareeyo liiska fursadaha suurtagalka ah shay la maamuli karo. Markaad tixgelinayso codsiga, waxaa muhiim ah inaad maskaxda ku hayso su'aalaha soo socda:
Halkee loo isticmaali doonaa qaybta?
Intee in le'eg ayaa cimrigeedu shaqayn karaa?
Waa maxay culaysyada ku lug leh codsiga?
Quruxdu door miyay ciyaaraan, mise wax qabadku waa muhiimada ugu wayn?
Waa maxay caqabadaha miisaaniyada codsiga?
Sidoo kale, su'aalaha hoose ayaa faa'iido leh marka la go'aaminayo waxyaabaha la doonayo:
Waa maxay sifooyinka farsamada iyo kiimikada looga baahan yahay caagga?
Sidee balaastiggu u dhaqmaa marka kululaynta iyo qaboojinta (tusaale, balaadhinta kulaylka iyo hoos u dhaca, kala duwanaanta heerkulka dhalaalka, heerkulka hoos u dhaca)?
Waa maxay isdhexgalka caagtu ay la leedahay hawada, balaastikada kale, kiimikooyinka, iwm.?
Hoos waxaa ku jira shax ka mid ah caagadaha isku durida ee caadiga ah, mid walbana wuxuu leeyahay faa'iidooyin u gaar ah iyo codsiyada warshadaha guud:

Thermoplastics ayaa ah doorashada la doorbido ee qaabeynta duritaanka. Sababo badan dartood sida dib-u-warshadaynta iyo fududaynta habaynta. Markaa meesha badeecada laga heli karo duritaanka qaabaysan iyadoo la isticmaalayo heerkulbeeg, u tag taas. Badeecooyin dabacsan oo sarreeya muddo dheer ayaa lagamamaarmaan u ah baahida loo qabo alastomers thermoset. Maanta waxaad haysataa ikhtiyaarka ah elastomers thermoplastic. Si qaybtaadu u noqoto mid aad u dabacsan kama saarayso ikhtiyaarka isticmaalka thermoplastics. Waxa kale oo jira darajooyin kala duwan oo TPE-yada laga bilaabo heerka cuntada ilaa TPE-yada waxqabadka sarreeya.
Caagagga badeecada waxaa loo isticmaalaa alaabooyinka maalinlaha ah ee macaamiisha. Tusaalooyinka waxaa ka mid ah koobabka qaxwaha ee polystyrene, maddiibadihii la qaadan lahaa ee polypropylene, iyo koofiyadaha dhalada polyetylen ee cufnaanta sare leh. Way ka jaban yihiin waana la heli karaa. Balaastigga injineernimada ayaa loo adeegsadaa, sida magacu tilmaamayo, codsiyada injineernimada. Waxaad ka heli doontaa guryaha lagu koriyo, go'yaasha saqafka, iyo qalabka. Tusaalooyinka waa polyamides (Nylon), polycarbonate (PC), iyo acrylonitrile butadiene styrene (ABS). Waxay u adkeysan karaan xaalado deegaan oo aad u adag. Waxay u adkeysan doonaan culeyska iyo heerkulka si ka sarreeya heerkulka qolka. Balaastigga waxqabadka sare leh ayaa si fiican u shaqeeya marka ay jiraan xaalado badeecadaha iyo balaastikada injineernimada ay ku fashilmaan. Tusaalooyinka balaastikada waxqabadka sare leh waa polyetylen ether ketone, polytetrafluoroethylene, iyo polyphenylene sulfide. Sidoo kale loo yaqaan PEEK, PTFE, iyo PPS. Waxay ka helaan isticmaalka codsiyada dhamaadka-sare sida hawada hawada, qalabka caafimaadka, iyo gearska. Waxqabadka sare waa ka qaalisan yahay badeecooyinka ama balaastikada injineernimada. Waxyaabaha balaastikada ah ayaa kaa caawin doona inaad go'aansato midka ku habboon codsi gaar ah. Tusaale ahaan, codsiyada qaarkood waxay u baahan yihiin qalab adag laakiin khafiif ah. Taas awgeed, waxaad is barbardhigtaa cufnaantooda iyo xooggooda.
