Yintoni iPolyChlorotriifriiforoothling (PCTFF)?

I-PCTF i-polymer ene-lelbone yoluhlu lwecandelo lokuphindaphinda eqaliswe yi-volymerication ye-vinyl trifluoride.

I-pctfe yi-crystalline polymer enendawo yokunyibilika yama-217 ° C kunye noxinzelelo lwe-2.13 g / cm3. I-PCTF ingena kwiikhemikhali ezininzi ezisebenzayo kubushushu begumbi, ngelixa inokuthi inyibiliswe ziinyibiliki ezimbalwa kwaye idumbile ngamanye amaxesha zingaphezulu kwe-212 ° C. I-pctfe inomsebenzi obalaseleyo wegesi.

I-PCTF inobuchule obukhulu begesi, kunye nokufakwa kwamanzi kwemveliso yefilimu yeyona nto iphantsi phakathi kwazo zonke iifilimu zeplasitiki ezifana ne-PCTLE. kwii-riements eziphezulu.

Imiyalelo yokusetyenziswa:

I-Polytrifuorororootheene ingabanda kakhulu, amandla aphezulu kunye nobunzima, uzinzo oluhle kunye notyekelo lokuhamba olubandayo. Ukuqhutywa kwe-DRM.25W / (MC), ukulandelela ukwanda kwe (9.5-19.6) * 10 ^ -5mpa, amandla e-win ^ Amandla e-70MPA. Inganyangeki kwi-Inorganic Acids kubushushu obuphezulu, ityiwa-ityiwa ityiwa ityiwa kwiqondo lokushisa eliphantsi, kwaye ikwanyangeke kakhulu kubushushu begumbi. I-PHIPE APREAR SEBENZISIWE I-25MPA.

Iipropathi eziphambili ze-PCTF:

1. Ngokwendlela yepropathi yoomatshini, iipropathi zobushushu begumbi le-PCTF ilunge ngakumbi kune-PTFE, amandla ayo oxinzelelo inkulu, ukuhamba kwesibanda kuncinci, ngokufumana kwakhona i-consec.

2. Ukunganyangeki kobushushu obuphantsi kwe-PCTB ye-PCTF kungabonakali ngakumbi, kwi-nitrogen yolwelo, i-oxygen ye-oxygen kunye negesi yendalo engaphandle kwendalo engaphandle kweBrittle, kwaye phantsi kweemeko ezithile zinokusetyenziswa kufutshane ne-zero (-273 ℃).

3. Umxholo ophezulu we-fluorine wenza i-pctfe enganyangekiyo phantse zonke iichemicals kunye nee-oxichers. Ingafakwa kwi-Acid, i-alkali okanye i-oxidizer ixesha elide ngaphandle kotshintsho, kwaye inokuchithwa kuphela kubushushu obuphakathiyo nge-Alkali i-Alkali kunye ne-chloorine kunye ne-chlorine ye-chifluoride.

Yintoni eyenza i-pctfe eyahlukileyo

Ukuthelekisa i-pctfe (i-Polynclorotriiflifyyyyyyyyylonene) ngePTFE Ekuqaleni, iifomula zemolekyuli ziyafana ngaphandle kwe-Atorine Atorine Atopher kwi-PTFE MOECULE iguqulwa kwi-Atom ye-chlorine.

Nangona kunjalo, oku kunokubonakala njengotshintsho oluncinci; Ukongezwa kweeathom ze-chlorine kukhokelela kumahluko omkhulu kwipropathi yokugqibela yezinto.

Makhe siqwalasele isiphumo seeathom ze-chlorine kwizinto ezibonakalayo:

Ukuchasana kwamachiza-ptfe yimolekyuli epheleleyo etyibilileyo kwaye ke iphantse ihlambulukene ne-acids. I-PCTF ityibilika ngokuyinxenye, kodwa ipolymer ineeatom ezintathu ze-fluorine, kwaye ke inayo imigangatho yekhemikhali, kodwa ayihambelani nemigangatho ephezulu ye-PTK, ngakumbi izinyibilikisi ezinamagama aneempuku.

Iipropathi zoomatshini - i-PTFI ihlala iyimveliso yokhetho xa i-voltages ephakamileyo, ukumelana okugqithisileyo kunye nokusebenza okuphezulu kuyafuneka. Nangona kunjalo, ukuba uzinzo oluphezulu oluninzi kuluhlu lobushushu olubanzi luyafuneka, okanye ukuba amandla aphezulu oomatshini uyafuneka, i-PTKI ayinakulunga kwesi sicelo. I-PCTF inamaxesha athile kabini amandla e-thenfe, kunye ne-elouty iphantsi kakhulu kunye nemodyuli ephantsi kakhulu kunye nemodyuli yentembeko engu-2,5 amaxesha e-TTFE.

Ipropathi ye-Thermal-ukongezwa kweeathom ze-chlorine inciphisa indawo yokunyibilika kwi-410 ° F ngokuthelekiswa nendawo yokunyibilika kwe-621 ° F. Oku kufuneka kuthathelwe ingqalelo kwisicelo sakho.

Isishwankathelo, uzinzo lwe-PCTF Luwela phakathi kwe-Polymers ekhethekileyo ekhethekileyo njenge-PPE, i-PPS kunye ne-PTFE, kodwa isasebenza ngokusebenza kakuhle. Ukongeza, i-pctfe inamaxabiso aphantsi kakhulu akhutshiwe kwaye avutha lula zii-fluoropolymers.
