Dunida qalabka warshadaha, ulaha PTFE (polytetrafluoroethylene) ayaa badanaa loo tixraacaa qaabka adag ee "boqorka caaga ah". Ma aha ul cad oo fudud; sidoo kale waa "geesiga gadaashiisa" ee xaalado badan oo heer sare ah oo dalbanaya. Haddii aad ka tirsan tahay mid ka mid ah qaybahan soo socda, ulaha PTFE waxay noqon karaan xalka ugu fiican ee aad raadineyso.
Haddii aad tahay injineer kiimiko ama deegaan "ku nool meel daxalka agteeda ah", usha PTFE waa "gaasha dahabka ah" ee qalabkaaga. Waxay si deggan u adkeysan kartaa nabaad-guurka muddada-dheer ee ka yimaada asiidhyada xooggan ee kala duwan, saldhigyada xooggan iyo dareerayaasha organic. Waa doorasho lagu kalsoonaan karo oo loogu talagalay xirmooyinka wax soo saarka, valves iyo dahaarka, ilaalinta badbaadada khadka wax soo saarka.
Haddii aad tahay xirfadle ka tirsan warshadaha caafimaadka ama cuntada oo qiimeeya "nadiifinta ugu dambeysa", firfircoonida nafleyda iyo sun la'aanta PTFE waxay ku siin doontaa xasilloonida maskaxda. Laga soo bilaabo qaybaha qalabka qalliinka ilaa meelaha xidhiidhka ee habaynta cuntada, waxay xaqiijin kartaa nadaafad buuxda iyo badbaado, baabi'inta khatar kasta oo faddarayn ah.
Haddii aad khabiir ku tahay "horumar weyn" xagga farsamada iyo farsamada, isku-dhafka aadka u hooseeya ee PTFE waa faa'iido dabiici ah. Waxay awood u siinaysaa xadhkaha iyo hagayaasha inay si habsami leh u socdaan iyada oo aan la sixin ama saliidayn ugu yar, si wax ku ool ah u yaraynaysa xirashada, isticmaalka tamarta iyo buuqa, iyo kor u qaadida cimriga iyo hufnaanta qalabka.
Haddii aad tahay injineer "tartan aad u daran" ee qalabka elektiroonigga ah ama hawada sare, hantida dahaarka ee wanaagsan iyo heerkulka ballaaran (-200 ° C ilaa + 260 ° C) ee PTFE ayaa ah muhiimad muhiim ah. Haddi ay ahaan lahayd wareegyada soo noqnoqda, qalabka semiconductor, ama diyaaradaha leh kala duwanaanshiyaha heerkulka aadka u daran, waa dammaanadda waxqabadka xasilloon.
Marka la soo koobo, qiimaha asaasiga ah ee usha PTFE waxay ku jirtaa "afar arrimood oo aan ahayn" sifooyinkeeda: uma nugulna daxalka, kama baqo heerkulka sare ama hooseeya, ma dhajin, mana qabato koronto.
Marka aad la kulanto caqabadaha asaasiga ah sida iswaafajinta kiimikada, dahaarka sare, khilaaf hoose, ama nadaafad sare, waxaa laga yaabaa inaad rabto inaad u jeediso dareenkaaga tan u muuqata mid caadi ah laakiin dhab ahaantii xoog badan usheeda cad. Waxa laga yaabaa inay tahay qaybta muhiimka ah ee ka maqan halxiraalaha mashruucaaga.
Shirkadeena waxay si qoto dheer ugu hawlan tahay beerista balaastikada injineernimada ee waxqabadka sare leh iyo agabka dahaadhka, waxaana ka go'an inay bixiso xalal wax ku ool ah oo loogu talagalay warshadaha wax soo saarka ee heer caalami. Alaabooyinkayaga ugu muhiimsan waxaa ka mid ah bacaha balaastigga ah ee injineernimada sare sida polyoxymethylene (POM), ABS, nylon (PA), polycarbonate (PC), polyphenylene sulfide (PPS), polyethermide (PEI), polyethertherketone (PEEK), iwm. Iyada oo leh sifooyin aad u fiican sida iska caabin heerkul sarreeya, xirashada iska caabinta, iyo xoog sare, alaabadayada waxaa si weyn loogu isticmaalaa gawaarida tamarta cusub, elektiroonigga smart, mishiinnada warshadaha, hawada hawada iyo meelo kale.
