Sida injineernimada waxqabadka sare, PPS (prolyphenylene sulfide sulfide) guddiga waxay muujiyeen faa'iidooyinkooda gaarka ah iyo awood ballaaran oo codsi ah oo ay ku badan yihiin beero badan. Waxyaabaha soo socdaa waa falanqayn dhameystiran oo ku saabsan astaamaha guddiga PPS:
1. Waxqabadka guud
Golaha PPS waa mid cad oo muuqaal ah, leh dhagaxa sare, waana polyter adag oo jilicsan. Cufnaanta qaraabada ee PPS saafiga ah waa 1.3, laakiin ka dib wax ka beddelka, cufnaanta ayaa sii kordheysa si ku habboon. PPS waxay leedahay nuugista biyo aad u hooseeya oo muujinaya iska caabin qoyan oo aad u wanaagsan. Intaas waxaa sii dheer, PPS waxay leedahay olole aad u wanaagsan oo dib-u-dhac ah, oo leh tusmo oksijiin ah oo ka badan 44%, taas oo ah darajo jilicsan oo olol ah oo ka mid ah agabyada caagga ah, iyadoo la siinayo dammaanad adag oo loogu talagalay isticmaalka nabdoon.
2. Guryaha farsamada
In kasta oo sifooyinka farsamada ee guddiga PPS ee saafiga ah aysan ahayn mid aad u fiican oo saameynta saameynta aad u yar, guryaha farsamada ayaa si weyn loo wanaajin karaa iyada oo loo sii mariyo furaha galaaska. Golaha PPS ee la xoojiyay ayaa leh awood aad u weyn oo ka badan wax ka badan 170mpa, xoog kor u kaca ah oo ah in ka badan 220mpa, iyo awood saameyn badan oo ka badan in kabadan 16MPA, oo muujinaya adkaanta aadka u sarreysa iyo xoog. Mooshaskeeda foosha (8gpa waxay ku gaari kartaa 3.8gpa ee gobolka PPS ee saafiga ah, waxayna gaari kartaa ilaa 12.6gpa ka dib wax ka badalida buuxinta ee gudaha ee INRENIC, balaastig aad u badan oo injineer ah sida PPO iyo PC. PPS sidoo kale waxay leedahay iska caabin heer sare ah iyo caabbinta daalance, adkeyn dusha sare ah Intaas waxaa sii dheer, astaamaha farsamada ee PPS-ka ayaa ka yar heerkulka waxayna muujinayaan xasillooni wanaagsan.
3. Guryaha kuleylka
Golaha PPS waxay leedahay xasillooni heer sare ah, oo leh meel dhalaalaysa in ka badan 280 ℃ iyo heerkul kulaylka kuleylka ah oo ka badan 260 ℃, waxaana loo isticmaali karaa muddo dheer 200 ℃. Hawada, PPS waxay xasilloon tahay 700 ℃ oo wali waxay hayn kartaa 40% culeyskeeda jawiga gaaska ee 1000 ℃. Wax ka badalida khaaska ah ka dib, heerkulka kuleylka kuleylka ee PPS ayaa lagu sii kordhin karaa in ka badan 350 ℃, la kulanka shuruudaha adeegsiga ee jawiga heerkulka sare.
4. Guryaha korantada
Golaha PPS waxay leeyihiin guryo koronto oo heer sare ah, oo leh dieltric-ka adag ee joogtada ah ee joogtada ah iyo daliishanka yar yar, iyo isbedel yar oo ku dhaca tiro badan oo heerkul ah iyo heerkul heer heerkul ah. Iska caabbinta ARC waa mid aad u fiican, oo loo barbardhigo balaastikada heerkullada, sidaa darteed waxaa badanaa loo isticmaalaa sidii qalab koronto oo koronto ah, oo ku mashquulsan qiyaastii 30% saamiyada suuqa.
5. Cadaadiska kiimikada
Golaha PPS waxay leedahay iska caabbinta kiimikada ee kiimikada ee kiimikada ah, iyo xasilloonideeda kiimikada ayaa ah kan labaad oo kaliya ee fluloplasts (F4). Waxay xasilloonayd in inta badan aashitada badankood, esters, ketones, 'aldenols', raashinnada, hydrocarbons, hyrocarbons-ka, hydrocarbons, iwm, oo aan xalline lagu baabi'in karo PPS ka yar 200 ° C. Isla mar ahaantaana, PPS waxay sidoo kale muujineysaa iska caabin adag oo ku saabsan aashitada injiin, alkalis iyo cusbada. Si kastaba ha noqotee, PPS uma adkeyso walxaha adag ee wasakhda leh sida biphenylls koloriin ah sida chlorinenyls-ka iyo aashitada oksidda, oxidas, aashitada sicir bararka, hydrogen peroxide iyo sodium hypochlorite.
6. Iskahorimaad shucaac ah
Golaha PPS waxay leeyihiin iska caabbial shucaac heer sare ah, oo qaddarka cadowga shucaaca ayaa gaari kara 1 × 10 ^ 8 gy. Astaamahani waa mid gaar u ah balaastigga injineernimada, taasoo ka dhigaysa wax ku habboon elektiroonig, koronto, mashiinno, qalab, duujin, iyo hawada.
7. Xasiloonida cabbirka
Golaha PPS waxay leeyihiin xasillooni murugo oo aad u wanaagsan, oo leh sicirka jajaban ee wax ka yar 0.0025%, heerka dhalmada biyaha ka yar 0.05%, iyo isbadal yar oo qashin qubka yar. Heerkulka sare iyo xaaladaha qoyaan sare, guddiga PPS ayaa wali ilaalin kara xasilloonida wanaagsan, sidaa darteed waxay leedahay rajo ballaaran oo arji ah mashiinno, warshadaha, aaladaha, duulista, maraakiibta, maraakiibta iyo beeraha kale.
8. Guryaha korantada ee heerkulka sare
PPS board can still maintain excellent electrical properties under high temperature, high humidity and high frequency conditions, with a volume resistivity of 1×1016 Ω·cm, a surface resistivity of 1×1015 Ω, and an electrical strength of more than 18KV/mm, providing reliable protection for electrical applications in high temperature environments.
9. olol dib u dhac ah iyo hantida is-deminta
Golaha PPS lafteeda ayaa leh guryo dib-u-dhac ah oo aad u wanaagsan, fasalka dib-u-dhigga ayaa gaari kara heerka Ul94, iyo tusaha oksijiinka (loi) ayaa ka sarreeya 57%. Qaab dhismeedka kiimikada wuxuu ku siinayaa guryo dib u dhac ah oo wanaagsan, oo waxay la kulmi kartaa shuruudaha ilaalinta dabka ee adag iyada oo aan lagu darin dib-u-celinta ololka.
10. Guryaha lagu dhaqo
Gudiga PPS waxay leeyihiin guryo dhajiya oo wanaagsan oo leh ashyaa'da birta iyo kuwa aan birta labadaba, gaar ahaan galaaska, aluminium, itanium, irl, irl la'aan iyo agabyo kale. Waxay leedahay xoog aad u sarreysa oo isku xiraya iyo adhesion gaarsiisa Heerka 1. Muuqaalkaani wuxuu ka dhigayaa PPS PLP-ka doorashada ugu habboon ee dahaarka qalabka kiimikada.
11. Waxqabadka Waxqabadka
Resin Golaha PPS ayaa leh jaceylka jahwareerka ah iyo dareeraha wanaagsan, waana ay fududahay in la qoyo oo lala xiriiro buugaagta sida fiber-ka, marka waa sahlan tahay in la buuxiyo buugaagta. Fibradda dhalada ama buufiyaha inorganic xooliyaha xoojiya ee loo yaqaan 'Choules' ee la isku diyaariyey ee ay diyaarisay waxay leedahay waxyaabo aad u sarreysa oo ka hortagga ah, iska caabbinta saamaynta, caabbinta saameynta, caabbinta caabbinta iyo kansarka. Heerkulka ka sarreeya meesha dhalaalaysa, guddiga PPS si isku mid ah loo sameysan karo, kaasoo bixiya ku habboonaanta howsha iyo wax soo saarka.
Marka la soo koobo, guddiga PPS waxay muujisay rajo ballaaran iyo suurtagal suuq suuq weyn iyo suuq weyn oo ay ku jiraan astaamo badan oo qaab ciyaareedkiisa wanaagsan. Iyada oo ay la socoto horumarinta tikniyoolajiyadda joogtada ah iyo ballaarinta joogtada ah ee aaladaha dalabka, guddiga PPS ayaa hubaal ka ciyaari doona door muhiim ah mustaqbalka.
Beerta ee balaastigga waxqabadka-sare, polythertotone), polyethetone), polyamide-imide (polyeride-imide), polyerimetone), polyeritides), iyo xaaladaha kale ee leh waxqabadka saafiga ah ee ugu wacan caabbinta heerkulka, xoogga sare, iyo guryaha wanaagsan ee xinjiriinta; PVDF (polyvinylide foloride) waxay ka ifisaa ilaalinta kiimikada kiimikada, kala-bixiyeyaasha tamarta ee cusub, iyo soosaarka dareeraha, iyo soosaarka dareeraha kiimikada ee ugu fiican iska caabbinta kiimikada ee wanaagsan, iska caabbinta cimilada, iyo pericectric-ka qaaska ah iyo guryaha ferroelectric. PPS (POLYPhenylene Sulfide), POLYPU (POLYPHYENENENE Sullfone), iyo PPU (badiyaa waxaa ka mid ah polymone-ka waxqabadka sare ee polyurethane ee wax laga beddelo, haddii ay ka hadlayso polymers-ka gaarka ah ee arjigaaga ah) sidoo kale si wanaagsan ayuu u sameeyaa. PPS waxay noqotay wax ku habboon baabuurta, qalabka elektiroonigga ah, iyo warshadaha kale sababtuna tahay astaamaha farsamada ee wanaagsan, iska caabinta kuleylka, iyo iska caabinta kiimikada; PPSU waxay si aad ah ugu qanacsan tahay maadooyinka caafimaadka iyo isku xirka cuntada oo ay ugu wacan tahay daadadkeeda, daahfurnaanta wanaagsan, iyo iska caabbinta ku-tallaalidda heerkulka heerkulka sare. Qalabkaani waxay leeyihiin awood u gaar ah oo ay si wada jir ah u dhiirrigeliyaan horumarka warshadaha casriga ah ee ku saabsan waxqabadka sare iyo waxqabadka badan.
