Tilmaamaha Alaabta
Shell iyo tuubada PTFE-ga beddelayaasha kulaylka waxay leeyihiin faa'iidooyin badan marka la barbar dhigo kuleyliyeyaasha walxaha birta ah.
1. Maadaama polytetrafluoroethylene (PTFE) ay tahay walxo kiimikaad ah (oo loo yaqaan F4) oo leh caabbinta daxalka wanaagsan, caabbinta daxalka ee fluoroplastics waa la yaqaan. Kulaylka la dhammeeyey ayaa loo adeegsaday in ka badan 100 warbaahin si meesha looga saaro heerkulka sare. Waxay ka shaqayn kartaa ku dhawaad dhammaan warbaahinta marka laga reebo fluorine elemental, biraha alkali dhalaalay, chlorine trifluoride, uranium hexafluoride, iyo kerosene perfluorinated.

2. Qalabka ka-hortagga wasakhda. Tuubooyinka caagga ah ee Fluorine waxay leeyihiin sagxadaha siman, balaadhinta kulaylka weyn iyo dabacsanaan weyn, taasoo ka dhigaysa inay yar tahay inay ururiyaan miisaan oo ay sameeyaan lakab miisaan. Waxay leeyihiin xasillooni kiimikaad oo wanaagsan inta badan warbaahinta waxayna si weyn u yareeyaan alaabada daxalka. ama la waayo. Dusha siman waxay leedahay sifooyin biyo-kordhin xoog leh, aan dheg lahayn iyo isku xidhka is-jiidhka oo aad u hooseeya, si wasakhda ama miisaanka lagu kaydiyo dusha gidaarka tuubada la yareeyo ama la tirtiro. Fluoroplastics waxay leeyihiin isugeyn balaadhin kuleyl weyn iyo dabacsanaan wanaagsan. Tuubooyinka kulaylka lagu beddelo ee ka samaysan fluoroplastics, gaar ahaan marka tuubooyinka isweydaarsiga kulaylku loo tolo qaab maroojin ah, waxay sababi doonaan gariirka tuubooyinka beddelka kulaylka ee ay sababaan kacsanaanta dareeraha, taasoo keenaysa lakabka miisaanka gidaarka tuubada inuu sidoo kale gariiro. dhici. Natiijo ahaan, gidaarka tuubada kuleyliyahaan wuxuu ahaanayaa mid nadiif ah inta lagu jiro hawlgalka muddada dheer.

3. Cabbir yar, miisaan fudud iyo qaab dhismeed is haysta. Dareenka kulaylka ee fluoroplastic waa hooseeyaa, kaliya 0.19W/m.℃, taas oo ah 1/250 ee birta kaarboon ee caadiga ah. Si loo yareeyo iska caabbinta kulaylka ee gidaarka tuubada oo loo kordhiyo wadarta isku-dhafka kulaylka, tuubooyinka dhuuban ayaa guud ahaan la isticmaalaa. Si loo hubiyo awoodda tuubooyinka derbiga dhuuban, tuubooyinka dhexroor yar waa in la isticmaalaa. Sababtoo ah isticmaalka tiro badan oo tuubooyinka dhexroorka yar yar, aagga wareejinta kulaylka mugga halbeegga waa weyn yahay. Tusaale: Marka la barbar dhigo miisaanka iyo mugga isla 10-square-meter kulaylka PTFE iyo birta ama kulaylka garaafiga aan biraha ahayn, kulaylka PTFE waa qiyaastii 1/2 ee labada kale. Waxaa la arki karaa in kulaylka noocaan ah uu noqon karo mid yar oo miisaankiisu yar yahay, miisaankiisuna fudud yahay, taas oo badbaadinaysa gaadiidka, rakibidda iyo kharashka hawlgalka.

4. La qabsi xoog leh. Sababtoo ah tuubada fluoroplastic waa jilicsan, waxay leedahay nolol caabbinta daalka foorarsan oo ka badan 100,000 jeer, iyo awoodda saamaynta 1.09J/cm³ ee -57 darajo iyo 1.63J/cm³ 23 darajo, xidhmada tuubada waxaa laga samayn karaa noocyo kala duwan oo loo baahan yahay. qaabab gaar ah. , oo si la isku halleyn karo ugu shaqeeyo muddo dheer xaaladaha saameynta dareeraha iyo gariirka. Tani way adagtahay in lagu gaadho walxaha kale ee u adkaysta daxalka sida graphite, galaas, ceramics iyo biraha dhifka ah.

5. Nolol adeeg oo dheer iyo dayactir fudud. Shirkaddayadu waxay leedahay aasaas weyn iyo horumarin xagga cilmi-baarista iyo horumarinta kulaylka fluoroplastic. Qaybaha u nugul gabowga iyo daxalka kuleyliyeyaasha kulaylka ayaa si tartiib tartiib ah loo hagaajiyay tallaabo tallaabo, iyo kuwa asalka ah waa la hagaajiyay. Iyadoo taas ku saleysan, waxaan sii cusbooneysiin doonaa si aan si wanaagsan ula qabsano macaamiisheena. Ilaa hadda, warshado badan ayaa isticmaalay kulaylka PTFE in ka badan 5 sano. Sidan, qayb weyn oo ka mid ah kharashka ayaa lagu badbaadiyay kulaylka beddelka oo keliya. . Marka labaad, kuleyliyaha PTFE waa sahlan tahay in la ilaaliyo. Haddii dheecaanku dhaco inta lagu jiro isticmaalka, waa la hagaajin karaa oo cadaadis si toos ah ayaa loogu tijaabin karaa goobta. Tani waxay badbaadisaa macaamiisha wakhtiga safarka wareega ah ee ay ugu soo laabanayaan warshadda si ay u dayactiraan iyo khasaaraha wax soo saarka ee ka yimaada baarkinka, taas oo ay adag tahay in lagu gaaro kulaylka kale.

6. Kharashku waa ujeeddo. In kasta oo fluoroplastics sida walxaha wareejinta kulaylku ay weli qaali yihiin hadda, iyadoo la adeegsanayo tuubooyinka gidaarada khafiifka ah ee dhexroor yar, guud ahaan isku-xidhka wareejinta kulaylku wuxuu noqon karaa ilaa 500W/㎡.℃. Tan waxa lagu soo saari karaa tiro badan iyadoo la raacayo shuruudaha habka wax soo saarka oo dhammaystiran. Nooc ka mid ah kulaylka beddelka, iyo ka sii muhiimsan, iska caabbinta daxalka sare waxay bedeli kartaa biraha dhifka ah, taas oo badbaadinaysa xaddi badan oo isticmaalka birta naadir ah. Intaa waxaa dheer, iyada oo ay ugu wacan tahay faa'iidooyinka iska caabbinta daxalka iyo caabbinta wasakhda ah ee kulaylka caagga ah ee fluorine, faa'iidooyin kale oo dhaqaale ayaa la heli karaa inta lagu jiro isticmaalka. Sidaa darteed, iyada oo la tixgelinayo arrimaha sida wax soo saarka, rakibidda, hawlgalka iyo dayactirka, kharashka dhabta ah waa mid hooseeya.
Faa'iidooyinka kor ku xusan waxaa si buuxda loo xaqiijiyay kuleyliyaha fluoroplastic loo isticmaalo wax soo saarka warshadaha, waxaana si weyn loogu isticmaalay warbaahinta kala duwan ee dibadda.
