Walxaha balaastigga ah ee Poly tetra fluoroethylene (PTFE), oo caadi ahaan loo yaqaan "boqorka balaastikada", waa polymer polymerized by ethylene tetrafluoroethylene sida monomer. Waxy cad, translucent, kulayl wanaagsan iyo iska caabin qabow, waxaa loo isticmaali karaa in -180 ~ 260 C muddo dheer. Maaddadani waxay leedahay sifooyinka anti-acid, anti-alkali, anti - dareerayaasha kala duwan ee organic, ku dhawaad aan la milmin dhammaan dareerayaasha. Isla mar ahaantaana, polytetrafluoroethylene waxay leedahay sifooyin heerkul sare ah, isugeynteeda isku-dhafka ah waa mid aad u hooseeya, sidaas darteed waxaa loo isticmaali karaa sifeynta, laakiin sidoo kale waxay noqotaa mid sahlan in la nadiifiyo dahaarka ugu fiican gudaha tuubada biyaha Material plastic Poly tetra fluoroethylene (PTFE) , oo inta badan loo yaqaan "boqorka balaastikada", waa polymer polymerized by ethylene tetrafluoroethylene sida monomer ah.

Waxy cad, translucent, kulayl wanaagsan iyo caabbinta qabow, waxaa loo isticmaali karaa in -180 ~ 260 C muddo dheer. Maaddadani waxay leedahay sifooyinka anti-acid, anti-alkali, anti - dareerayaasha kala duwan ee organic, ku dhawaad aan la milmin dhammaan dareerayaasha. Isla mar ahaantaana, polytetrafluoroethylene waxay leedahay sifooyin heerkul sare ah, isku-dhafka is-jiidhisku waa mid aad u hooseeya, sidaas darteed waxaa loo isticmaali karaa sifeynta, laakiin sidoo kale waxay noqotaa mid sahlan in la nadiifiyo daboolka ku habboon gudaha tuubada biyaha.
Ku xasil heerkulka caadiga ah iyo cadaadiska, ka fogow huurka iyo kulaylka, ma jirto meel dhalaalaysa oo dhab ah oo heerkulkeedu sarreeyo, si tartiib ah u qudhunto meel ka sarreysa 450 ℃ oo si toos ah u isu beddela gaas. Markay ahayd 327 ℃, xoogga farsamada ayaa si lama filaan ah u lumay. Aan milmi karin.
Marka laga reebo awoodda ay u leedahay in ay ka falceliso biraha alkali ee dhalaaliyay, ma aha wax nabaadguur ah oo ku yimaada walxo kasta, mana isbedesho xitaa marka lagu kariyo hydrofluoric acid, aqua roya, ama qiiqa sulfuric acid, ama sodium hydroxide.2. Caddaan, aan ur lahayn, aan dhadhamin iyo budo aan sun ahayn, oo caadi ahaan loo yaqaan "boqorka balaastikada".
Waxay leedahay xasillooni kiimikaad oo heer sare ah, iska caabin daxalka, xidhidhiyaha, muuqaal la'aanta sare, dahaarka korantada iyo adkaysiga wanaagsan ee gabowga.
Iska caabbinta heerkulka sare, heerkulka hawlgalka ilaa 250 ℃. Heerkulka hooseeya ee caabbinta heerkulka hooseeya, heerkulka hooseeya wuxuu leeyahay qallafsanaan farsamo oo wanaagsan, xitaa haddii heerkulku hoos u dhaco -196 ℃, wuxuu ilaalin karaa 5% elongation.
Iska caabbinta daxalka, inta badan kiimikooyinka iyo dareerayaasha si ay u muujiyaan qallafsanaanta, aashitada xooggan iyo alkali, biyaha iyo noocyo kala duwan oo dareerayaasha organic. Caabbinta cimilada wanaagsan, nolosha gabowga ugu fiican ee balaastikada.
Saliid sare, waa isku-dhafka walxaha adag ee ugu hooseeya.
Aan-ku-dhejin, waa maaddada adag ee xiisadda ugu yar ee dusha sare, ma aha inay u hoggaansamaan wax kasta.
Aan sun ahayn, oo leh firfircooni nafsiyeed, sida xididdada dhiigga ee macmalka ah iyo xubnaha jirka lagu dhex beeray muddo dheer iyada oo aan lahayn fal-celin xun.
Si ballaaran loo isticmaalo mishiinada, qalabka, qaybaha baabuurta, korontada iyo elektiroonigga ah, tareenka, qalabka guriga, isgaarsiinta, mashiinada dunta, ciyaaraha iyo alaabta madadaalada, tuubooyinka saliidda, haamaha shidaalka iyo qaar ka mid ah alaabta injineernimada saxda ah.

SPCT66G15/20/30 | 15%-30% | HB/V0 | Labbiska u adkaysta oo sarreeya waa la hagaajiyey, muddada dheer iyadoo la isticmaalayo kulayl ahaan deggan, degganaansho cabbir kiimiko ahaan u adkaysta, qallafsanaan sarreeya, adkaysi u leh. PTFE adkaysi u leh asiidhka iyo saldhigyada, adkaysi u leh dareerayaasha kala duwan ee organic, waana kuwo aan lagu milmi karin dhammaan dareerayaasha. Isla mar ahaantaana leh sifooyinka heerkulka sare, isugeynteeda isku-dhafka ah waa mid aad u hooseeya, sidaas darteed waxaa loo isticmaali karaa sifeynta. Marka lagu daro PPS, PPA, PA66, PA46, MOS2, waxay si weyn u wanaajin kartaa iska caabbinta xidhashada, is-jiidhka iyo sifooyinka silbashada viscous ee alaabtan. Si ballaaran loo isticmaalo in lagu sameeyo gears, biraha iyo jilbaha, sidoo kale waxaa loo isticmaalaa in lagu beddelo doorka sifeynta qaybaha birta, yaraynta miisaanka qaybaha iyo dhimista kharashka dayactirka. |
