Kulezi zinsuku, imikhiqizo eminingi ivelele ekuthuthukisweni kobuchwepheshe kanye nemboni, futhi i-PTFE tube ingenye yale mikhiqizo edlala indima ebalulekile emikhakheni eyahlukene. Kodwa wake waphawula ukuguga kwe-Amashubhu e-PTFEUkusebenza kwamashubhu e-PTFE kuzoncipha ngemva kokuguga. Ngakho-ke uchungechunge lwezinyathelo kufanele luthathwe ukuvimbela ukuguga esigabeni sokugcina sokukhiqizwa kwamashubhu e-PTFE. Ukuguga kwamashubhu e-PTFE kungokwemvelo futhi akunakuvinjelwa, kodwa okuwukuphela kwento ongayenza ukunciphisa ijubane lokuguga Amashubhu e-PTFE. Ukuze usize ekunciphiseni izinga lokuguga kwamashubhu e-PTFE, kufanele uqinise ukugcinwa kokusetshenziswa kwamashubhu e-PTFE futhi uthathe izinyathelo eziningana zokuvimbela lesi simo.I-Besteflon ikunikeza izindlela ezine eziyinhloko zokunciphisa ijubane lokuguga kwe-PTFE tube yakho.
1. Uma ukhetha izinto zokulinganisa zamashubhu e-PTFE, kufanele usebenzise uhlelo lokwelapha i-sulfur noma nini lapho kungenzeka. Ngenxa yokumelana nokushisa kwerabha yayo evulcanized, ingashintshwa ngokunciphisa noma ukugwema ukusetshenziswa kwe-elemental sulfur, enganciphisa noma isuse ama-crosslink e-polysulfide futhi ikhiqize ikakhulukazi ama-crosslink e-monosulfide noma e-disulfide, ngaleyo ndlela yehlisa ukuguga kwe-I-PTFE amapayipi.
2. Ukuqinisekisa ukuthi izinto zifinyelela ukumelana nokushisa okufiselekayo, ukusetshenziswa kwe-peroxide kuyadingeka. Kulesi simo, i-peroxide vulcanization ikhiqiza ikhabhoni enokuqina okungcono kokushisa kanye nezibopho zokuxhumanisa ikhabhoni.
Umkhiqizi we-PTFE tube uphinde aphawule ukuthi kufanele unake kakhulu ezinye izithasiselo ekusebenziseni ama-peroxide. Isibonelo, ukukhetha ama-antioxidants kudingeka kube nzima kakhulu, njengoba amaningi awo ephazamisa ukwenziwa kwama-peroxide abe yingozi. Ngakho-ke, ungasebenzisa namafutha e-paraffin, isithasiselo esisebenzayo esingeke siphazamise ukwenziwa kwama-peroxide abe yingozi.
3. Ngaphezu kwalokho, ukuze kuvinjelwe ukuhlukaniswa kwe-peroxide cation futhi kugwenywe ukuvunguza okuphansi kakhulu kwepayipi elinomfutho ophezulu (okuboniswa ubulukhuni obuphansi, i-modulus ephansi kanye nokucindezelwa okuphezulu kanye nokuguquguquka kwesikhathi eside), kufanele usebenzise i-peroxide ukunciphisa inani le-acidic filler. Uma kungenzeka, ukungezwa kwamakhemikhali e-alkaline (isb. i-zinc oxide noma i-magnesium oxide) kuvame ukuthuthukisa ukusebenza kahle kwe-cross-linking ye-peroxide.
4. Uma ukhiqizaI-PTFE amashubhu, ezinye izithasiselo zingangezwa, njenge-antioxidants, kanye nama-alkaline compounds, njll., ukuze kuthuthukiswe ukusebenza kahle kwe-cross-linking kwama-peroxide futhi kubambezele ukuguga kwe-I-PTFE amapayipi.
