Ibikoresho bya PVDF ni iki?
Polyvinylidene Fluoride (PVDF) ni ibikoresho bikora cyane bikoreshwa cyane mu nganda zikora imiti n’inganda, kandi bitoneshwa kubera imiti irwanya imiti, imiterere y’amashanyarazi n'imbaraga za mashini. Muri iki kiganiro, tuzasesengura mu buryo burambuye icyo PVDF aricyo, imiterere yacyo, imikoreshereze nuburyo bwo gukora kugirango tugufashe kumva neza ibyiza byibi bikoresho.
Ubwa mbere, ibyingenzi biranga PVDF
PVDF ni kimwe cya kabiri cya kirisiti ya fluoropolymer ya termoplastique, cyane cyane polymerised ikomoka kuri vinylidene fluoride (VDF) monomer. Bitewe na electronegativite ya atome ya fluor n'imbaraga z'umubano wa CF, PVDF yerekana ibintu bikurikira:

Kurwanya imiti: PVDF irwanya cyane aside nyinshi, alkalis, umunyu hamwe nuwashonga, bigatuma itajegajega kandi ikarwanya ruswa munganda zikora imiti mugihe runaka.

Imbaraga za mashini: PVDF ifite imbaraga zidasanzwe kandi zirwanya ingaruka, ikabasha gukomeza ubusugire bwimiterere yabyo mubidukikije bikaze

Ibikoresho by'amashanyarazi: Bitewe na dielectric nkeya ihoraho kandi iringaniza cyane, PVDF ikoreshwa cyane mumashanyarazi na elegitoronike, cyane cyane nk'ibikoresho byo kubika insinga n'insinga.

Ubushyuhe bwumuriro: PVDF ifite ubushyuhe bwiza bwumuriro kandi irashobora gukoreshwa mubushuhe butandukanye, kandi mubisanzwe irashobora kugumana imiterere yumubiri mubushuhe bwa -40 ° C gushika kuri 150 ° C.

Icya kabiri, inzira yo gukora PVDF
Umusaruro wa PVDF ugerwaho ahanini binyuze muri polymerisation yubusa, mubisanzwe hakoreshejwe polymerisation cyangwa guhagarika polymerisation. Muburyo bwa polymerisation, monomers ya VDF ihindurwamo polymer ya PVDF mubihe byihariye. Nyuma yibyo, binyuze murukurikirane rwibikorwa nyuma yubuvuzi, harimo kwezwa, gukuramo no guhunika, gushinga kwa nyuma ibicuruzwa bya PVDF bifite imiterere yihariye.
Icya gatatu, ibyingenzi byingenzi bikoreshwa muri PVDF
PVDF yakoreshejwe cyane mu nganda nyinshi kubera imikorere yayo myiza:

Inganda zikora imiti: PVDF isanzwe ikoreshwa mugukora ibikoresho bitandukanye bya chimique, imiyoboro na valve, cyane cyane mugihe kirimo imiti yangiza.

Inganda zubaka: PVDF ikoreshwa mugukora imyenda ikora cyane, nka fluorocarubone, ikoreshwa mukurinda inkuta zinyuma zinyubako, kandi irashobora kugumana ubwiza bwinyubako igihe kirekire kubera imiterere ya UV hamwe nubusaza.

Inganda za elegitoroniki n’amashanyarazi: PVDF ikoreshwa cyane mugukora insinga, umuhuza hamwe na diaphragm ya batiri ya lithium kubera amashanyarazi meza cyane hamwe no kurwanya ubushyuhe.

Inganda zitunganya amazi: Ibikoresho bya PVDF bikoreshwa mubijyanye no gutunganya amazi, cyane cyane muri ultrafiltration na nanofiltration membrane, bitoneshwa kubera imiti myinshi yo kurwanya imiti no kuyungurura neza.

Icya kane, ibyifuzo byisoko nibibazo bya PVDF
Hamwe nihuta ryinganda ninganda ziyongera kubikoresho bikenerwa cyane, isoko rya PVDF riratera imbere byihuse.Ibiciro byumusaruro mwinshi hamwe nuburyo bugoye bwo gutunganya umusaruro wa PVDF bituma igiciro cyacyo gihenze. Ikoreshwa rya PVDF naryo rihura ningorane zimwe na zimwe kubera ibibazo by’ibidukikije bijyanye na fluor. Kubwibyo, kunoza imikorere yumusaruro no kugabanya ingaruka z’ibidukikije bya PVDF bizaba urufunguzo rwiterambere.
Incamake
Ibikoresho bya PVDF ni iki? Binyuze mu isesengura ryavuzwe haruguru, turashobora kubona ko PVDF ari ibikoresho bya fluoropolymer ikora cyane hamwe nibintu byinshi byifuzo byo gusaba. Kurwanya imiti myiza cyane, imbaraga za mashini, ibikoresho byamashanyarazi hamwe nubushyuhe bwumuriro bituma bigira uruhare runini mubice byinshi. Hamwe nogutezimbere ibisabwa byo kurengera ibidukikije, umusaruro nogukoresha PVDF nabyo bizahura nibibazo bishya n'amahirwe. Gusobanukirwa no kumenya neza imitungo nibisabwa bya PVDF birashobora gutanga inkunga ikomeye yo guhanga udushya no guteza imbere inganda zijyanye.
