Iindaba - yeyiphi ipayipi ye-ptfe eguquguqukayo ngakumbi okanye ipayipi ye-polyurethane

Yeyiphi indlela engcono yokusebenza

Zombini ityhubhu yePTFE kunye netyhubhu yePU zisetyenziswa kakhulu kumashishini ahlukeneyo, kodwa indawo yokusetyenziswa kwezi zimbini ayifani. Ityhubhu yePTFE isetyenziswa kwindawo yokusebenza egqithisileyo, kwaye ubungakanani bayo buphelele, amashishini afanelekileyo abanzi kakhulu kunetyhubhu yePU. Ipayipi yePU ifanelekile ukusebenza phantsi koxinzelelo oluqhelekileyo kunye nobushushu. Ngenxa yokuba izinto zayo zithambile kwaye ziyanwebeka, inokugotywa ngokuthanda kwayo. Ifanelekile ngakumbi kwiindawo ezimxinwa okanye kwiindawo ezinerediyasi ephezulu yokugoba.

Oku kulandelayo yintshayelelo eneenkcukacha zeentlobo ezimbini zeetyhubhu:

Ityhubhu ye-PTFE:

Umbhobho wePtfe ngumbhobho okhethekileyo owenziwe ngezinto zePTFE emva kokukhupha nokukrwitsha, ukomisa, ukukrwitsha ngobushushu obuphezulu, kunye nokubumba. I-Polytetrafluoroethylene (PTFE) inozinzo oluhle kakhulu lweekhemikhali, olufana:

1. Ayimelani nobushushu obuphezulu kunye noxinzelelo oluphezulu. Ingasetyenziswa ixesha elide kwi -65℃ ~ 250℃ phantsi koxinzelelo oluqhelekileyo. Emva kweeyure ezili-1000 zonyango lobushushu obuphezulu kwi-250℃, iimpawu zayo zoomatshini aziyi kutshintsha kangako.

2. Ilwa nokugqwala kwaye ilwa nokwaluphala, inokumelana nazo zonke ii-asidi ezinamandla, ii-alkali ezinamandla, ii-oxidants ezinamandla, kwaye ayizukusebenzisana nezinyibilikisi ezahlukeneyo zezinto eziphilayo.

3. Ukukhusela ubushushu. Ngenxa yokuba i-PTFE ayinayo i-polarity, ukumelana nobushushu kwaye ayinamanzi, ikwayinto efanelekileyo yokukhusela ubushushu ngombane.

4. I-coefficient ephantsi yokungqubana. I-PTFE ine-coefficient ephantsi kakhulu yokungqubana. Yinto elungileyo yokulwa ukungqubana kunye nokuzithambisa. I-coefficient yayo yokungqubana engaguqukiyo ingaphantsi kwe-coefficient yokungqubana okuguquguqukayo. Ke ngoko, ineengenelo zokuxhathisa ukuqala okuphantsi kunye nokusebenza kakuhle xa isetyenziselwa ukwenza iibheringi.

5. Ayitshisi, ayinatyhefu, ilula, iguquguquka kakuhle kunye nezinye iimpawu, uluhlu olubanzi lokusetyenziswa, akukho lula ukuyonakalisa, ubomi obude bokusebenza, akukho mfuneko yokutshintshwa rhoqo lolona phawu luxabisekileyo.

Injongo yombhobho we-PU:

Isetyenziswa kakhulu kwiimoto, kwi-aerospace, kwi-hydraulics, kwi-pneumatics, kwiindlela zikaloliwe, kwi-processing yokutya, kwi-fluid transportation, kwi-chemical transportation, kwi-manufacturing nakwi-petrochemical, kwi-electronic product insulators, njl.

Umbhobho wePolyurethane:

Ityhubhu yePolyurethane yityhubhu yePU, eyahlulwe yaba yityhubhu eqinileyo kunye nepayipi, ityhubhu ecacileyo, njl. Uphawu oluphambili kukuba ityhubhu ithambile kwaye inokufumana irediyasi encinci yokugoba. Ngenxa yokukhanya kwayo nokuthamba, kulula kwaye kuyaguquguquka ukuyisebenzisa. Iipayipi zePU zisetyenziswa kakhulu kwiipayipi zomoya, iipayipi zamanzi kunye neepayipi zokuhambisa izinto ezinoxinzelelo oluqhelekileyo lokusebenza kunye nobushushu. Kodwa xa kuthelekiswa neepayipi zePTFE, iipayipi zePU zisengozini yokwaluphala kunye ne-hydrolysis kwaye zinobomi obufutshane benkonzo. Uzinzo lweekhemikhali alulunganga, olufana:

1. Uluhlu lobushushu bokusebenza luphakathi kwe -20° kunye ne +60°;

2. Ukumelana nokugqwala kubuthathaka, akukwazi ukumelana nee-asidi ezinamandla kunye nee-alkali, kwaye kusabela lula kwezi mveliso zeekhemikhali.

3. Uxinzelelo olusebenzayo lungaphakathi kwe-10kg kuphela, olungenakusetyenziswa kwindawo yokusebenza enoxinzelelo oluphezulu.

4. Inamandla okuxhathisa ukuguguleka, inoluhlu olubanzi lwezicelo ekuthuthweni kwezinto eziphathekayo.

5. Irediyasi yokugoba incinci. Ngenxa yokuba umbhobho we-PU uthambile kwaye unobuthambile obuhle, ufanelekile ekwakheni imibhobho.

6. Ityhubhu ye-PU icacile kakhulu, kwaye imeko yokuhamba okuphakathi ibonakala ngokucacileyo.

Injongo yombhobho we-PU:

Ifanelekile kushishino, kwezolimo, ekutyeni, kwezonyango, kubunjineli bokwakha, kwezokuloba, kwezolimo zasemanzini, ekunkcenkcesheleni igadi, kwioyile engangcolisiyo nakwezinye iindawo. Ukuba ifuna ukugcina ubomi bayo obude, kufuneka ibe phantsi koxinzelelo olulinganisiweyo lokusebenza kunye nokusingqongileyo. Sebenzisa kubushushu. Njengoko ubushushu bunyuka, uxinzelelo lokusebenza kufuneka lwehle ngokufanelekileyo. Ukuba umda udlulile, ipayipi inokuqhekeka. Ubushushu bolwelo buphezulu kakhulu okanye ulwelo luneendleko zeekhemikhali ezingcolisayo, ezinokubangela ukuba ipayipi iqhekeke, ubushushu bendawo yokusebenza buphezulu kakhulu okanye indawo yokusebenza ineegesi zeekhemikhali, ezinokubangela ukuba ipayipi iqhekeke, igcinwe kwindawo efumileyo okanye ixesha lokugcina liphelile. Ixesha elide, iya kusebenzisa i-hydrolyze okanye igugise ipayipi, enokubangela ukwaphuka.
