PTFE vs Silicone

I-Silicones, eyaziwa ngokuba yi-polysiloxanes, iipolymers ezibandakanya nayiphi na i-inert, i-synthetic compound eyenziwe ngamacandelo aphindaphindayo e-siloxane, engumxokelelwane we-athomu ye-silicon etshintshanayo kunye ne-athomu ye-oxygen, ehlala idibaniswa ne-carbon kunye / okanye i-hydrogen.Ngokuqhelekileyo ziyakwazi ukumelana nobushushu kwaye zifana nerabha, kwaye zisetyenziswa kwizitywini, izinto zokuncamathelisa, izinto zokuthambisa, iyeza, izixhobo zokupheka, kunye nokugqunywa kwe-thermal nombane.Ezinye iifom eziqhelekileyo ziquka ioli ye-silicone, i-silicone grease, i-rubber ye-silicone, i-silicone resin, kunye ne-silicone caulk.I-Silicones zintathu iindidi: 1. i-silicone chain chain;2. ii-silicones ze-cyclic;3. i-silicones edibeneyo.

I-hose yococeko ibandakanya ngokubanzi kwiinkqubo zenkqubo yokusetyenziswa kwamayeza.Nokuba yitanki ephathwayo ye-hook ups, i-isolators yeeseli zomthwalo, i-CIP jumpers okanye nasiphi na esinye seshumi elinambini lezicelo, iindibano zemibhobho yococeko zikuyo yonke indawo.Kufuneka zibe sterilzable ngomphunga okanye autoclave ngaphandle komonakalo.Kukho izinto ezimbini kuphela ezihlangabezana neemfuno zamachiza ngaphandle kokuhlangabezana nezikhokelo ze-FDA: I-silicone eqinileyo ecocekileyo kunye ne-PTFE egudileyo (ipolymer).Yiyiphi enye engcono ukuyisebenzisa?Kuxhomekeke kwisicelo kunye nesiphumo esizama ukusifezekisa:

IiPropathi zeSilicone ezicocekileyo eziLilide

Ukukhanya kubunzima kakhuluIi-Silicone eziguquguqukayo kakhulu aziyivumeli irhasi okanye ulwelo ukuba ludluleIyaziwa ngokomelela kwayo kunye nokukwazi ukumelana neekhemikhali zokusabelaUkwazi ukusetyenziswa kwindawo evalelwe iintsholongwane kunye nokukwazi ukumelana nobushushu obugqithisileyo kunye nokubamba ubushushu (kubandakanya ukusetyenziswa kwe-cryogenic) Akukho "ziphumo eziphawulweyo ezinobungozi kwizinto eziphilayo. kwimekobume ziye zaqatshelwa ii-silicones.Ngenxa yokuba zisetyenziswa ngokubanzi, zixhaphakile, zihlaziywa ngokukhawuleza, njengoko zenziwe ngodongwe olwahlukeneyo.

Iipropati ze-PTFE Hose

● Inzima kakhulu (xa kuthelekiswa nesilicone) ● Yomelele kune-silicone (isenokunqweneleka okanye inganqweneleki ngokuxhomekeke kwisicelo) ● I-pyrolysis ye-PTFE ibonakala kwi-200 °C (392 °F), kwaye ibandakanya iigesi ezininzi ze-fluorocarbon kunye ne-sublimate.

Ngoko ke, loluphi ukhetho olungcono lwebhobho?Nangona umsebenzi wesicelo ubalulekile ngelixa umahluko weendleko phakathi kwezi zimbini awubalulekanga kakhulu.Imibhobho ye-PTFE iyakhethwa ukuba ungena kwizicelo ezingaphezulu kwe-100 PSI.Kodwa ukuba ufuna into elula kwaye ebhetyebhetye njengaleyo yokutsiba kweseli yomthwalo omfutshane, i-silicone isebenza kakuhle.
