Namuhla, imikhiqizo eminingi igqame ekuthuthukisweni kobuchwepheshe nezimboni, futhi PTFE tube ingenye yalezi mikhiqizo edlala indima ebalulekile emikhakheni ehlukahlukene.Kodwa wake waphawula ukugugaAmashubhu e-PTFE?Ukusebenza kwamashubhu e-PTFE nakho kuzoncishiswa ngemva kokuguga.Ngakho-ke uchungechunge lwezinyathelo kufanele luthathwe ukuvimbela ukuguga esigabeni sakamuva sokukhiqizwa kwamashubhu e-PTFE.Ukuguga kwamashubhu e-PTFE kungokwemvelo futhi akunakuvinjelwa, kodwa into kuphela ongayenza ukunciphisa isivinini sokuguga. Amashubhu e-PTFE.Ukusiza ukubambezela izinga lokuguga lamashubhu e-PTFE, kufanele uqinise ukunakekela ekusebenziseni amashubhu e-PTFE futhi uthathe uchungechunge lwezinyathelo zokuvimbela lesi simo.LaphaBesteflon ikunikeza izindlela ezine ezinkulu zokwehlisa isivinini sokuguga seshubhu yakho ye-PTFE.
1. Lapho ukhetha usayizi wempahla yamashubhu e-PTFE, kufanele usebenzise uhlelo lokwelapha isibabule noma nini lapho kunokwenzeka.Ngenxa yokumelana nokushisa kwenjoloba yayo ene-vulcanized, ingashintshwa ngokunciphisa noma ngokugwema ukusetshenziswa kwe-elemental sulfur, enganciphisa noma isuse i-polysulfide crosslinks futhi ikhiqize ikakhulukazi i-monosulfide noma i-disulfide crosslinks, ngaleyo ndlela yehlise ijubane ukuguga.I-PTFE amashubhu.
2. Ukuqinisekisa ukuthi impahla ifinyelela ukumelana nokushisa okufunayo, ukusetshenziswa kwe-peroxide kuyadingeka.Kulokhu, i-peroxide vulcanization ikhiqiza i-carbon ene-thermal stability engcono kanye ne-carbon cross-linking bond.
Umkhiqizi wamashubhu we-PTFE uphinde aphawule ukuthi kufanele unake ngokukhethekile ezinye izithasiselo ekusebenziseni ama-peroxides.Isibonelo, ukukhetha kwama-antioxidant kufanele kuqine kakhulu, njengoba amaningi awo aphazamisa ukukhishwa kwama-peroxides.Ngakho-ke, ungasebenzisa futhi amafutha kapharafini, isithasiselo esisebenzayo esingeke siphazamise i-peroxide vulcanization.
3. Ngaphezu kwalokho, ukuze uvimbele ukuhlukaniswa kwe-peroxide cation futhi ugweme ukuvuthwa okuphansi kakhulu kwe-hose ephezulu yokucindezela (okuboniswa ubulukhuni obuphansi, i-modulus ephansi kanye nokucindezela okuphezulu kanye nokuguqulwa kwesikhathi eside), kufanele usebenzise i-peroxide ukuze unciphise inani le-acidic filler.Uma kungenzeka, ukwengezwa kwezinhlanganisela ze-alkaline (isb. i-zinc oxide noma i-magnesium oxide) ngokuvamile kuthuthukisa ukusebenza kahle kokuxhumanisa kwe-peroxide.
4. Lapho ukhiqizaI-PTFE amashubhu, ezinye izithasiselo zingangezwa, njengama-antioxidants, nezinhlanganisela ze-alkaline, njll., ukuze kuthuthukiswe ukusebenza kahle kokuxhumanisa ama-peroxides futhi kubambezele ukugugaI-PTFE amashubhu.
