Iqondo lobushushu obuphezulu lokutywina: I-Peek vs. Ptfe

Xa kufikwa kubushushu obuphezulu bezinto zokutywina, ukuthelekisa zihlala zenziwa kukhuphiswano. Umzekelo, i-Peek (Polyteether Ether Itone) kunye ne-PTFE (POLYTETROFLUOOTELLE) Zombini zezona zinto zisetyenziswa zininzi zeqondo lobushushu. Izinto nganye zinamandla awo ahlukileyo kunye nobuthathaka, kodwa yintoni umahluko phakathi kwezi zinto zimbini xa ifumaneka kwizicelo eziphezulu zokuhlawula ubushushu? Okulandelayo, eli nqaku liza kubonelela ngophawu olucacileyo lwezi zinto zimbini kwezi nkalo zintathu zilandelayo.

Ukunganyangeki kobushushu

Ngelixa zombini i-ptfe kunye ne-Peek inesibindi esihle sokuchasana nobushushu, banamaqondo ahlukeneyo amaqondo ahlukeneyo eRanges.peek isebenza kakuhle kumaqondo obushushu ukuya kwi-260 ° C, enza ilungele uluhlu olubanzi lwezicelo. Ngapha koko, kwelinye icala, ngelixa ikwakwazi ukumelana nobushushu obuphakamileyo, ilahlekile ezinye iipropathi zayo kumaqondo obushushu angama-210 ° C. Oku kuthetha ukuba i-ptfe isenokungahlali ixesha elide njenge-peek kwiindawo zobushushu obuphezulu.

Ukuxhathisa iikhemikhali

Bobabini i-Peek kunye ne-PTFO banamanyano olupheleleyo lwekhemikhali, bebenza balungele ukusetyenziswa kwiindawo ezinomsindo. Nangona kunjalo, i-Peek ayikaxhathisi ngobuchwephesha njenge-PTFE, ethetha ukuba kwiindawo ezithile ezonakalisayo, i-PTPE inokulunga njengezinto zokutywina. Nangona i-peek incinci kancinci kancinci kancinci kune-ptfe, isamela kakhulu ichaphaza ngeekhemikhali.

Iipropathi zoomatshini

I-Peks ineepropathi ezigqwesileyo zendlela, kunye neepropathi zayo zoomatshini, kubandakanya amandla e-thansile kwaye zinxibe ukuxhathisa, ziphezulu kwe-ptfe. Xa kuthelekiswa ne-PTFE, i-Peek ineepropathi ezibalaseleyo. Oku kuthetha ukuba i-Peek ilungele ukusetyenziswa kwezicelo ezifuna ukuzinza komhlaba kunye noomatshini.

Kwisishwankathelo, i-Peek kwaye i-ptfee zombini zigqwesileyo zeqondo lobushushu, kodwa kukho umahluko othile ekusebenziseni kwabo. Ukuqonda lo mahluko kunokukunceda ukhethe eyona nto ifanelekileyo kwisicelo sakho seqondo lobushushu. Nceda wenze ukhetho olunolwazi ngokusekwe kwimeko yesicelo edityanisiweyo kunye noku kungentla.
