PTFE powder A na-ejikarị ya eme ihe dị ka ihe mgbakwunye na mkpuchi dị iche iche nke na-agbaze na ntụ ntụ, dị ka mkpuchi plastik, agba osisi, mkpuchi mkpuchi, mkpuchi mkpuchi UV, na agba, iji melite arụmọrụ ntọhapụ ebu ha, nguzogide elu elu, mmanu mmanu, kemịkalụ na-eguzogide. iguzogide ihu igwe, na mgbochi mmiri. PTFE Enwere ike iji obere ntụ ntụ mee ihe dị ka ihe na-esi ísì siri ike kama ịbụ mmanụ mmiri mmiri. Enwere ike iji ha mee ka mmiri nke ink dịkwuo mma yana dịka onye na-egbochi iyi uwe, yana ihe mgbakwunye 1-3wt. A pụkwara iji ha mee ihe na mkpuchi na-adịghị mma maka kichin, na-enwekarị ihe mgbakwunye na-emekarị karịa 5wt%. A pụkwara iji mgbasa ihe mgbaze organic mee ihe dị ka ihe ntọhapụ. Enwere ike iji ha dị ka ihe na-egbochi ntapu nke ukwuu na rọba dị iche iche, dị ka ABS, polycarbonate (PC), polyurethane (PU), na polystyrene (PS).
PTFE bụ polymer crystalline nke ukwuu nke sitere na tetrafluoroethylene monomers, nwere mkpuchi ọkụ eletrik mara mma, esemokwu dị ala na ọnụọgụ esemokwu, enweghị ọkụ, iguzogide ịka nká nke ikuku, mgbanwe dị elu na nke dị ala, yana akụrụngwa akụrụngwa dị elu.
Otú ọ dị, n'ihi nhazi ya nke ukwuu na nke na-abụghị polar, enweghi otu ndị na-arụ ọrụ, na nnukwu crystallinity. PTFE bụ ihe na-abụghị polar nke nwere hydrophobicity siri ike, kemịkalụ kemịkalụ, ike dị ala, na wettability na-adịghị mma na adhesion na ihe ndị ọzọ, nke na-egbochi ngwa ya nke ukwuu. Ya mere, ịgbasa ngwa nke PTFE, A ghaghị ịgwọ elu ya iji mee ka ike elu ya dịkwuo elu ma melite hydrophilicity ya.
Ọgwụgwọ Plasma bụ otu n'ime teknụzụ na-eto ngwa ngwa maka PTFE mgbanwe elu n'afọ ndị na-adịbeghị anya. Ụkpụrụ nke mgbanwe plasma bụ iji ion bombardment ma ọ bụ injection n'elu polymer iji mepụta agbụ gbajiri agbaji ma ọ bụ webata otu ndị na-arụ ọrụ, si otú a na-eme ka elu dị elu iji welie ihe dị n'elu. Gasị ndị a na-ejikarị eme ihe gụnyere oxygen, hydrogen, nitrogen, carbon tetrafluoride, na argon. Bọmbụ nke plasma inert gas nwere ike gbanwee nhazi elu nke copolymer.
Plasma nwere ihe ndị na-arụ ọrụ dị ka eletrọn, ion, na radicals efu. Mgbanwe ihu igwe nke plasma gụnyere mgbanwe anụ ahụ na kemịkal. Mgbanwe nke anụ ahụ bụ ogbunigwe nke electrons na ion n'elu polymer, nke na-agbaji njikọ kemịkalụ nke yinye polymer, na-ebute mmeghachi omume nbibi, ma mepụta ngwaahịa mmebi nke na-edobe n'elu polymer. Mgbanwe kemịkalụ gụnyere iwebata otu ndị na-arụ ọrụ site na radicals na-emeghachi omume na elu polymer, na-agbanwe ihe mejupụtara kemịkalụ nke elu. Ma mgbanwe anụ ahụ na nke kemịkal ga-eme ka mgbanwe dị na njirimara elu. N'oge ọgwụgwọ plasma, iwebata ndị otu na-arụ ọrụ na mmeghachi omume mmebi ahụ enweghị ike ikewapụ ma na-eme n'otu oge, mmeghachi omume mmebi bụ ihe a na-apụghị izere ezere. Isi ihe na-eme mgbanwe n'elu dị irè bụ ibelata mmeghachi omume nrụrụ aka ma bulie ọrụ nke iwebata otu ọrụ.
The PTFE mgbanwe ntụ ntụ na-eji igwe nhicha plasma ntụ ntụ. Plasma na-arụ ọrụ na ntụ ntụ iji jiri nlezianya gbanwee ihe anụ ahụ na nke kemịkal ya, ebe ọ na-ejigide ihe mbụ nke ntụ ntụ, iji nye ya ihe ndị dị n'elu, na-agbanwe ihe ndị dị n'elu ya site na hydrophobic ka hydrophilic ma ọ bụ nke ọzọ, si otú a na-eme ka wettability nke ntụ ntụ ntụ. ime ka adhesion nke ntụ ntụ na ọkara.
