Umuyoboro wa ptfe urimo imiyoboro ni iki | BESTEFLON

Mu myaka ya vuba aha, polytetrafluoroethylene (Teflon) ni ubwoko bw'ibicuruzwa birwanya ihumana n'ihumana mu nganda zikora ingufu z'amashanyarazi na peteroli. Ariko, ibibazo bikurikira bigomba kwitabwaho cyane iyoImirongo ya PTFEumuyoboroumurongo urimo gusudira, bitabaye ibyo ubuzima n'umutekano by'umuyoboro wa PTFE bizahungabanywa.

1. Mu gusukura ibikoresho byo guteranya, birabujijwe cyane kwangiza icyuma cy'ibanze. Birabujijwe gukubita umugozi ku cyuma cy'ibanze mu gihe cyo gusudira.

2. Mu gice cy'urushundura rw'urushundura, uburebure bw'urushundura rw'urushundura rugomba kurenza mm 5, inguni y'icyerekezo igomba kurenza mm 3 cyangwa ingana na mm, naho inguni y'imbere ikaba kurenza mm 10 cyangwa ingana na mm.

3. Mu gusudira igikonoshwa cy'umuyoboro wa PTFE, ni byiza gukoresha uburyo bwo gusudira bwo gusudira impande ebyiri. Ibi bisaba urwego rwa tekiniki rw'abakozi bacu, gusudira bigomba kuba birambuye (bidahinduka neza cyangwa byoroshye), nta myenge, umushongi wo gusudira n'ibintu bivanze, kandi uburebure bw'ukusudira ntibugomba kurenza mm 2. Nyuma yo gusudira, umwanda uterwa no gusudira ugomba gukurwaho burundu.

4. Gusudira bidatinze bigomba gukoreshwa mu gusudira umuyoboro wa PTFE, kandi umushongi wo gusudira ntugomba kugira icyuho cyangwa gukata bidatinze.umuyoboro wa PTFE wometseho, Umuyoboro wa PTFE urimo urujya n'uruza

Polytetrafluoroethylene (PTFE) ni rimwe mu mazina akunze gukoreshwa ya polytetrafluoroethylene. Umuyoboro wa PTFE ukoreshwa mu muyoboro w'icyuma kitagira umugese, bityo ubuzima bw'umuyoboro ni burebure cyane kuruta umuyoboro wa rubber cyangwa umuyoboro wa rubber upfunyitse mu cyuma kitagira umugese. Ufite ibyiza byinshi ugereranije n'ibicuruzwa bya rubber.

Icyiciro cya mbere: Imiyoboro igororotse n'ibikoresho bya PTFE

Bizwi cyane nk'umuyoboro w'amazi ufunguye. Muri ubu buryo, PTFE ikoreshwa mu guzunguruka umugozi. Ikwiriye imiyoboro isanzwe yo gutwara umuvuduko n'umuvuduko mwiza (nk'imiyoboro itatu yo gutunganya imyanda, nibindi), kandi ntigomba gukoreshwa ku muyoboro ufite umutwaro (nk'aho ipompo yinjira n'aho isohoka n'umuyoboro ushobora gutanga umuvuduko mubi bitewe no kugwa cyangwa gukonjesha mu buryo butunguranye).

Ibipimo by'umurambararo: dn25-500mm

Ubushyuhe bwa serivisi: - 40-180oc

Umuvuduko wa serivisi: 1.6Mpa

Icyiciro cya II: Imiyoboro ya PTFE igororotse kandi igororotse ifite umurongo ugororotse

Bizwi cyane nk'umuyoboro upfunyitse neza upfunyitse mu nsinga z'icyuma.

Uburyo bwo gukora: icya mbere, ibice byinshi bya PTFE filime bihambirwa ku ibumba, hanyuma insinga y'icyuma (Ø 0.5-1mm) igahambirwa ku ruziga kuri PTFE filime, hanyuma ibice byinshi bya PTFE filime yoroheje bigahambirwa inyuma y'insinga y'icyuma, hanyuma bigapfunyikwa mu itanura kugira ngo bikore. Urukuta rw'imbere rw'umuyoboro wa PTFE wakozwe n'ubu buryo ruraryoshye, kandi urukuta rw'inyuma rufite uruziga rumeze nk'uruziga bitewe n'ingano n'imbaraga zoroshye z'insinga z'icyuma.

Umwanya uri hagati y'urukuta rw'inyuma rw'umuyoboro wa PTFE n'urukuta rw'imbere rw'umuyoboro w'icyuma wuzuramo resin (nta mwuka usigaye). Resin yuzuza ishobora gufatanywa neza n'umuyoboro w'icyuma. Muri icyo gihe, ishobora gupfundikirwa neza ku rukuta rw'inyuma rw'umuyoboro wa PTFE. Nyuma yo gufunga resin yuzuye, umuyoboro w'uruziga ukorwa ufunganye n'umuyoboro w'inyuma w'umuyoboro. Iyi miterere isa n'uruvange rwa nut na bolt. Ku ruhande rumwe, ishobora kugabanya no kwishyura kwaguka k'ubushyuhe n'ubukonje bw'umuyoboro wa PTFE; ku rundi ruhande, gukomera kw'insinga z'icyuma bishobora kunoza cyane uburyo PTFE idashobora guhangana n'umuvuduko.

Ibipimo by'umurambararo: dn25-200 mm

Ubushyuhe bw'akazi: - 50-180oc

Umuvuduko w'akazi: 0.5-1.6mpa

Ubwoko bwa gatatu: Umuyoboro wa PTFE upfunyitse neza ufite umuyoboro ugororotse

Izwi cyane nka "push (squeeze) lined straight pipe", ikoreshwa cyane mu bihugu byateye imbere mu myaka ya 1990.

Uburyo bwo gukora: icya mbere, ifu ya PTFE itumizwa mu mahanga ikoreshwa mu gusunika (gusohora) umuyoboro, hanyuma igashyirwa mu muyoboro w'icyuma udakora (umurambararo w'inyuma w'umuyoboro uruta gato umurambararo w'imbere w'umuyoboro w'icyuma kuri mm 1.5-2) kugira ngo habeho umurongo uhamye udakora. Kugira ngo ukureho umuvuduko, ishyirwa mu itanura igashyushya kugeza kuri dogere selisiyusi 180 kugira ngo ikoreshwe mu bushyuhe buhoraho, kugira ngo ishobore gukoreshwa mu bushyuhe buri munsi ya dogere selisiyusi 180. Muri icyo gihe, sunika (kanda) umuyoboro w'umuyoboro

Ingufu zo gukurura ziruta iz'umuyoboro w'igisebe. Umuyoboro ufite ubushobozi bwo guhangana n'igitutu cyiza n'ikibi.

Itandukaniro riri hagati y'urupapuro rwa PTFE n'urupapuro rwa rubber

Tetrafluoroethylene yo gushyiramo umugozi ikoreshwa mu kurwanya ingese ya fluorine, kurwanya ubushyuhe bwinshi, kurwanya aside na alkali cyane, gufatana neza, kumara igihe kirekire no kurwanya cyane kwinjira. Tetrafluoroethylene yose yo gutera ni akazi gakomeye, ni iyihe nzira ikoreshwa? 1. Mbere yo gutera, ubuso bugomba gusimburwa no gukaraba, hanyuma hagaterwa urwego rwa primer yihariye. 2. Hanyuma ifu ya fluoroplastic ishyirwamo ibikoresho bya electrostatic bifite voltage nyinshi, kandi bigashyirwa ku buso bw'igikoresho munsi y'ingufu z'amashanyarazi. 3. Nyuma yo guteka ubushyuhe bwinshi, uduce twa clinker tuzashonga tukavamo urwego rwo kurinda, rufatanye neza n'ubuso bw'igikoresho. Urugero, agapira k'ubugari bwa mm 1 na ko gakwiye guteranywa no gutekwa inshuro 5-6. Muri rusange, ubugari ntarengwa bushobora guteranywa kugeza kuri mm 2. Udupira twa PTFE ni ikoranabuhanga rikoreshwa cyane muri iki gihe. Ikoresha neza uburyo fluorine irwanya ingese, ubuziranenge bwinshi, isuku, kudafatana, kudatose, kwisiga amavuta, kudasaza, kudashyuha cyane, kudashyuha cyane, gukingira ubushyuhe bwinshi n'ubukonje, gukingira ubushyuhe, nibindi. Mu gihe cyo kubaka, ingufu zayo n'amashanyarazi bihora bihinduka kugira ngo bigere ku rwego rwiza kugira ngo bigere ku ngaruka zo gusiga. Umwambaro wa rubber witwa kandi umwambaro wa rubber. Ni ugufata isahani ya rubber yatunganyijwe ku buso bw'icyuma ukoresheje kole kugira ngo utandukanye icyuma gihumanya n'icyuma kugira ngo ukingire. Rubber karemano na rubber ya sintetike bikoreshwa mu kwambara. Rubber nyinshi zikoreshwa mu kwambara ibikoresho bya shimi ni rubber karemano. Igice cy'ingenzi cya rubber karemano ni cis polymer ya isoprene, ivungagurishwa no kongeramo sulfur. Rubber yavungagurishijwe ifite ubushobozi bwo kurwanya ubushyuhe n'imbaraga za mekanike. Ishobora kugabanywamo ubwoko butatu bwa rubber yoroshye, rubber isanzwe n'urubber ikomeye. Rubber ikomeye ifite ubushobozi bwo kurwanya ingese, idasaza kandi ikomeye hamwe n'icyuma. Rubber yoroshye ifite ubushobozi bwo kurwanya ubukonje, idashyuha kandi idakora neza, kandi ifite ubushobozi bwo kurengera; rubber ikomeye iri hagati ya ebyiri. Uretse ogisijeni zikomeye n'ibindi bintu bishongesha, rubber ikomeye ishobora kurwanya kwangirika kwa aside nyinshi zitari umwimerere, aside organic, alkali, umunyu na alcool. Kubwibyo, umwambaro ukomeye wa rubber ukoreshwa nk'ikintu cy'ingenzi kidakoreshwa mu byuma birwanya kwangirika. Rubber ya Vulcanized ishobora kugabanywamo rubber ya vulcanized, rubber ya vulcanized isanzwe ikoreshwa mu mazi ashyushye, rubber ya vulcanized isanzwe ikoreshwa mu buryo busanzwe. Rubber ya vulcanized ikoreshwa mu bikoresho binini byo gusya.
