Ibintu bikeneye kwitabwaho mugihe cyo kubaka ibyuma - umurongo wa ptfe

Mubuzima bwa buri munsi dushobora kubona kenshi umuyoboro wa ptfe, none, umuyoboro wa ptfe mugikorwa cyo gutunganya dukeneye kwitondera icyingenzi?

Mubikorwa byo kubaka ibyuma bitondetse umuyoboro wa PTFE, ingingo zikurikira zigomba kwitabwaho:

1. umuyoboro wicyuma udafite uburinganire ukurikije ubunini nyabwo bwibikoresho, umuyoboro wibyuma hamwe no gusudira impeta yo gusudira, impeta irashobora gukoresha intoki ya argon arc gusudira, gusudira gusudira hamwe na dosiye kugirango isukure, hamwe na fillet isudira mu mfuruka izengurutse, nta shiti inkombe.

2. Gucukura umwobo muto kumpera yicyuma, ushire akamenyetso neza, kandi ntukibuze.Uyu mwobo ukoreshwa mu gusohora gaze isigaye hagati y'umuyoboro w'icyuma n'umuyoboro wa tetrafluoroethylene mu gihe cyo gushyushya, kandi ikoreshwa mu kureba niba umuyoboro wa tetrafluoroethylene wangiritse kandi ukameneka mu gihe cyo gupima igitutu.

3. umuyoboro wibyuma ugomba kubanza guteranyirizwa mbere yo gutonda umurongo.Ihuriro rigomba guteranyirizwa hamwe na zahabu ya asibesitosi yuburebure bukwiye, kugirango ihuze nubunini rusange busabwa nyuma yo gutonda umurongo.

4. nyuma yo guteranya umuyoboro wibyuma bidafite kashe kugirango bivurwe n'umucanga, kugirango ukureho ingese y'urukuta rw'imbere, hanyuma hamwe n'umwuka uhumanye kugirango usukure umwobo.Shyiramo tetrafluoroethylene umuyoboro mu cyuma.Niba umuyoboro wa tetrafluoroethylene udafite uruziga kandi ntushobora kwinjizwamo, amazi ashyushye, itanura cyangwa itanura rishyushye rigomba gukoreshwa mu gushyushya umuyoboro wa tetrafluoroethylene, ubushyuhe bwo hejuru ntiburenga 100 ℃.

5. Reba uburebure bwa flanging mugihe ukata umuyoboro wa teflon.Mubisanzwe, uburebure bwa 35-40 bushyirwa kuruhande hejuru yimpeta yo gusudira.Igipimo cya zahabu ya asibesitosi kigomba gushyirwa kumuyoboro wa TEflon mbere yo guhindagurika.Kuzunguza umuyoboro wa teflon mu ntambwe ebyiri, ubanza mu nzogera, iyi flanging ukoresheje icyuma cya aluminiyumu.Iyo uhindagurika, shyushya vivipary n'umuriro wa oxyacetylene.Ubushyuhe bwa fixture bupimwa hamwe na semiconductor hejuru ya termometero.Ubushyuhe ntibukwiye kuba hejuru cyane.Ubushyuhe bugomba kugenzurwa hagati ya 260 ℃ na 280 ℃.Mugihe uhindagurika, kanda buhoro buhoro igituba gishyushye.Iyo imyenda yo kubyara igeze kumpera yimpeta yo gusudira, ntukongere gukanda.Muri iki gihe, shyushya amazi hanyuma ukureho imyenda yo kubyara iyo ikonje kubushyuhe bwibidukikije.Guhindagurika kwintambwe ya kabiri birushijeho gushira nozzle.Iyi iringaniye.

6. nyuma yo gushyushya, kanda buhoro hanyuma ukande rwose, hanyuma ukonje n'amazi kubushyuhe bwibidukikije, hanyuma ukureho icyuma.

7. umuyoboro utondekanye hamwe nisahani nziza ihumye, muri silinderi idasanzwe yo gushyushya, ihujwe numuyoboro woguhumeka, gushyushya silinderi hamwe nuburyo bwo gushyushya intera hagati, kuburyo ubushyuhe rusange bwumuyoboro bugera kuri 280 ℃, hanyuma buhoro buhoro 8-LOKGF / cm2 umwuka ucometse.Shira umuyoboro wa tetrafluoron mu kigega cy'amazi, winjize umuyoboro mu mazi, unyure buhoro buhoro mu kirere cyugarije 15kgf / cm2, urebe niba hari ibibyimba ku mwobo, niba bibonetse, byerekana ko umuyoboro wa tetrafluoron wacitse.Impamvu ahanini ni ukubera ubushyuhe butaringaniye cyangwa umuvuduko wifaranga byihuse.Umuyoboro wicyuma utondekanye ugomba gufungwa kumpande zombi hamwe nisahani ihumye kugirango wirinde kwangirika kwa tetrafluoron.
