Daaweynta dusha sare ee Polytetrafluoroethylene (PTFE)

Sida soo saaraha ilo xirfadle ah oo ka samaysan dharka heerkulka sare ee PTFE, Jiangsu Aokai Qalabka Cusub ayaa soo bandhigi doona daaweynta dusha sare ee polytetrafluoroethylene (PTFE).

PTFE waxay leedahay iska caabin heerkul aad u sarreeya oo hooseeya, caabbinta daxalka kiimikaad oo heer sare ah, isugeyn hoose iyo sifooyin is-saliim ah. Waxaa si weyn loogu isticmaalaa qalabka elektiroonigga ah, mishiinada, qalabka kiimikada, hawada hawada, biomedicine iyo meelo kale, taasoo kasbaday sumcadda 'King of caagadaha' . Si kastaba ha ahaatee, sababtoo ah la'aanta kiimikada iyo tamarta hoose ee hoose, PTFE way adag tahay in lagu xiro alaabta kale, taas oo xaddidaysa codsigeeda ilaa xad. Si loo hagaajiyo adhesion u dhexeeya PTFE iyo qalab kala duwan, hababka waxaa sida caadiga ah la qaatay si kor loogu qaado dhaqdhaqaaqa dusha ee PTFE. Alaabooyin kala duwan, Qalabka Cusub ee Aokai wuxuu guud ahaan khuseeyaa hababka soo socda ee wax ka beddelka dusha sare ee PTFE.

1. Daaweynta Kiimikada qoyan

Daawaynta kiimikada sodium -naphthalene  waa mid ka mid ah hababka waxtarka leh ee wax ka beddelka dusha sare ee PTFE. Habka fudud iyo qiimaha jaban, waa doorashada la doorbido ee wax soo saarka wax ku oolka ah ee Aokai New Materials 'warshada PTFE.

Daawaynta Sodium-naphthalene inta badan waxay isticmaashaa xal jeexjeex ah si ay kiimiko ahaan uga falceliso PTFE, ka saarta qaar ka mid ah atamka fluorine ee dusha sare. Tani waxay ka tagtaa lakab kaarboonaysan waxayna soo bandhigtaa kooxaha polar sida kooxaha hydroxyl, kooxaha karbonyl iyo curaarta aan saturated lahayn. Kooxahan polar-ka ah waxay kordhiyaan tamarta dusha sare ee polymer-ka, waxay yareeyaan xagasha xiriirka waxayna wanaajiyaan qoyaanka, sidaas awgeed PTFE ka soo jeeda kuwa aan la isku dhejin karin

2. Habka Isku-xidhka Mechanochemical

Marka polymers-ka la hoos geeyo xoogag dibadeed (tusaale, burburin, shiidi, khilaaf, iwm.), silsiladaha makromolecular jebiya oo ay galaan falcelin kiimikaad, oo ay ku jiraan mechanodegradation, makaanochemical crosslinking, mechanochemical ku tallaalid, block copolymerization iyo polymerization-ka-firfircoon. Kuwaas waxaa loo yaqaan falcelinta makaanikada kiimikada polymer.

Isku-xidhka makaanikada, dusha sare ee polymer-ka koollada leh waa la xoqay. Iyada oo loo marayo ficilka makaanikada, dusha sare ee polymer wuxuu maraa mechanodegradation si uu u sameeyo xag-jiryada xorta ah ee macromolecular, ka dibna sameeya bonds covalent leh molecules dhejis ah, abuurista isku xirnaanta adag oo si weyn u wanaajinaya xoogga isku xirnaanta ee wadajirka.

3. Habka Heerkulka Sare

Mabda'a aasaasiga ah ee wax ka beddelka sagxadaha PTFE iyada oo loo marayo dhalaalid heerkul sare ah waa: heerkulka sare, qaab-dhismeedka crystalline ee dusha PTFE waa la beddelaa, iyo tamar-sare-sare, qalabka si fudud u xiran sida SiO₂ iyo Al budada ayaa lagu dhejiyaa. qaboojinta ka dib, lakab la bedelay oo ay ku jiraan walxo la isku xidhi karo ayaa ka samaysanaya dusha PTFE. Maaddaama molecules-ka alaabta la isku xidhi karo ay galeen lakabka molecular ee PTFE, jebinta curaarta waxay u baahan tahay burburin intermolecular, taasoo keentay xoog isku xidhid sare ah.

4. Habka Shucaaca

PTFE waxaa lagu meeleeyaa monomers-ka falcelisa polymerizable sida styrene, fumaric acid, methacrylates iyo kuwa kale, ka dibna lagu shubo Co-60 . Tani waxay kicisaa polymer-ka-tallaalidda kiimikaad ee monomer-yada dusha sare ee PTFE, samaynta lakabka-polymer-ka-tallaalidda oo ay fududahay in lagu xidho. Ku-tallaalid waxay sidoo kale qallajisaa dusha sare, waxay kordhisaa aagga isku-xidhka waxayna kordhisaa xoogga isku-xidhka.

5. Farsamada Daaweynta Plasma

Daaweynta Plasma waa mid ka mid ah tignoolajiyada ugu dhaqsaha badan ee horumarinta wax ka beddelka dusha sare ee PTFE sanadihii ugu dambeeyay.

Nuxurka tignoolajiyadaani waa in la geliyo muunada aaladda daawaynta balaasmaha ee go'an, halkaas oo ion bombardment ama implantation ay jebiyaan curaarta molecular ama ay soo bandhigaan kooxo shaqeynaya dusha polymerka, iyaga oo dhaqaajinaya dusha sare si loo gaaro isbeddel. Ions waxay noqon karaan gaas aan shaqaynayn, gaasas kiimiko ah ama walxo macdan ah. Bambooyinka gaasaska aan shaqaynayn ayaa wax ka beddeli kara qaabka dusha sare ee polymerka.

Macluumaadka sare waxaa bixiyay Jiangsu Aokai New Materials Technology Co., Ltd.

Si aad u hesho cabbirro faahfaahsan, xaaladaha codsiga iyo xalalka loo habeeyey ee kala duwanaanta badeecadeena oo dhan - oo ay ku jiraan PTFE maro heerkul sare leh, PTFE cajalad heerkul sare leh, PTFE suunka mesh heerkulka sare, suumanka aan kala go 'lahayn ee mashiinnada isku xidhka, maro PTFE hal dhinac ah, heerkul sare oo u adkaysta suumanka dhalada, fadlan nala xiriir
