Matsatsing ana, lihlahisoa tse ngata li hlahella nts'etsopele ea mahlale le indasteri, 'me tube ea PTFE ke e 'ngoe ea lihlahisoa tsena tse bapalang karolo ea bohlokoa masimong a fapaneng. Empa na u kile ua hlokomela botsofali baLiphaephe tsa PTFE? Tshebetso ya dipeipi tsa PTFE le yona e tla fokotseha ka mora ho tsofala. Kahoo letoto la mehato le lokela ho nkuwa ho thibela botsofali mohatong wa morao wa tlhahiso ya dipeipi tsa PTFE. Botsofali ba dipeipi tsa PTFE ke ba tlhaho mme bo ke ke ba thibelwa, empa ntho feela eo o ka e etsang ke ho fokotsa lebelo la botsofali ba Lipeipi tsa PTFE. Ho thusa ho fokotsa sekhahla sa botsofali ba lipeipi tsa PTFE, o lokela ho matlafatsa tlhokomelo ha o sebelisa lipeipi tsa PTFE le ho nka mehato e mengata ho thibela boemo bona.Besteflon e u fa mekhoa e mene e meholo ea ho fokotsa lebelo la botsofali ba tube ea hau ea PTFE.
1. Ha o kgetha thepa ya boholo ba diphaephe tsa PTFE, o lokela ho sebedisa sistimi ya ho phekola sebabole neng kapa neng ha ho kgoneha. Ka lebaka la ho hanyetsa mocheso wa rabara ya yona e qhibilihisitsweng, e ka fetolwa ka ho fokotsa kapa ho qoba tshebediso ya sebabole sa motheo, se ka fokotsang kapa sa tlosa di-crosslink tsa polysulfide mme sa hlahisa haholo-holo di-crosslink tsa monosulfide kapa disulfide, ka hona se diehisa botsofali baPTFE liphaephe.
2. Ho netefatsa hore thepa e fihlella ho hanyetsa mocheso ho lakatsehang, ho hlokahala tšebeliso ea peroxide. Tabeng ena, peroxide vulcanization e hlahisa carbon e nang le botsitso bo betere ba mocheso le maqhama a hokahanyang carbon.
Moetsi oa tube ea PTFE o boetse o hlokomela hore o lokela ho ela hloko ka ho khetheha lintho tse ling tse tlatsetsang tšebelisong ea li-peroxide. Mohlala, khetho ea li-antioxidants e hloka ho ba thata haholoanyane, kaha tse ngata tsa tsona li sitisa ho vulcanization ea li-peroxide. Ka hona, u ka boela ua sebelisa oli ea parafini, e leng setlolo se sebetsang se ke keng sa sitisa ho vulcanization ea peroxide.
3. Ho phaella moo, e le ho thibela karohano ya peroxide cation le ho qoba ho vulcanization e tlase haholo ya hose ya kgatello e phahameng (e bontshwang ke ho thatafala ho tlase, modulus e tlase le kgatello e phahameng le ho fetoha ha nako e telele), o lokela ho sebedisa peroxide ho fokotsa bongata ba asiti e tlatsang. Haeba ho kgoneha, ho eketswa ha metsoako ya alkaline (mohlala, zinc oxide kapa magnesium oxide) hangata ho ntlafatsa bokgoni ba ho kopanya ba peroxide.
4. Ha o hlahisaPTFE lipeipi, li-additives tse ling li ka eketsoa, tse kang li-antioxidants, le metsoako ea alkaline, jj., e le ho ntlafatsa katleho ea li-peroxide le ho liehisa botsofali baPTFE liphaephe.
