Ọgwụgwọ elu nke Polytetrafluoroethylene (PTFE)

Dị ka onye ọkachamara na-emepụta akwa akwa okpomọkụ PTFE, Jiangsu Aokai New Materials ga-ewebata ọgwụgwọ elu nke polytetrafluoroethylene (PTFE).

PTFE atụmatụ magburu onwe elu na ala okpomọkụ nguzogide, pụtara ìhè corrosion nguzogide, a ala esemokwu ọnụ ọgụgụ na onwe-lubricating Njirimara. A na-eji ya eme ihe na ngwa elektrọnik, igwe, akụrụngwa kemịkalụ, ikuku ikuku, biomedicine na mpaghara ndị ọzọ, na-enweta aha nke 'Eze Plastics' . Agbanyeghị, n'ihi inertness kemịkalụ ya na ike dị ala dị ala, PTFE siri ike ijikọ ya na ihe ndị ọzọ, nke na-egbochi ngwa ya ruo n'ókè ụfọdụ. Iji meziwanye adhesion n'etiti PTFE na ihe dị iche iche, a na-ejikarị ụzọ eme ihe iji welie ọrụ elu nke PTFE. Maka ngwaahịa dị iche iche, Aokai New Materials na-emetụta usoro mgbanwe elu elu PTFE ndị a.

1. Ọgwụgwọ kemịkalụ mmiri

Ọgwụgwọ kemịkalụ sodium-naphthalene  bụ otu n'ime ụzọ dị irè maka mgbanwe elu elu PTFE. Site na usoro dị mfe yana ọnụ ala dị ala, ọ bụ nhọrọ kachasị mma na mmepụta bara uru na ụlọ ọrụ PTFE Aokai New Materials.

Ọgwụgwọ Sodium-naphthalene na-ejikarị ngwọta etching emeghachi omume na PTFE, na-ewepụ ụfọdụ atom fluorine n'elu. Nke a na-ahapụ oyi akwa carbonized wee webata otu pola dị ka otu hydroxyl, otu carbonyl na njikọ ndị na-adịghị mma. Ndị otu polar ndị a na-abawanye ike elu nke polymer, belata akụkụ kọntaktị ma melite wettability, si otú a na-atụgharị PTFE site na enweghị ike ịbanye n'ime njikọ.

2. Mechanochemical bonding Method

Mgbe ndị polymer nọ n'okpuru ike mpụga (dịka ọmụmaatụ, ịkụpịa, egweri, esemokwu, wdg), ụdọ macromolecular na-agbaji ma na-enweta mmeghachi omume kemịkalụ, gụnyere mechanodegradation, mechanochemical crosslinking, mechanochemical grafting, block copolymerization and stress-activated polymerization. A maara ndị a dị ka mmeghachi omume mechanochemical polymer.

Na mechanochemical bonding, a na-ehichapụ elu polymer mkpuchi nrapado. Site na mechanochemical edinam, polymer elu na-enweta mechanodegradation na-etolite macromolecular free radicals, nke ahụ na-etolite covalent bond na ụmụ irighiri ihe, na-eke a ike bonding interface na-eme ka nke ukwuu bonding ike nke nkwonkwo.

3. Ụzọ mgbaze dị elu

Ụkpụrụ bụ isi nke imegharị PTFE elu site na mgbaze dị elu bụ: na okpomọkụ dị elu, a na-agbanwe ọdịdị crystalline morphology nke elu PTFE, na elu elu-ike, ngwa ngwa jikọtara ihe dị ka SiO₂ na Al ntụ ntụ. Mgbe jụrụ oyi, oyi akwa gbanwetụrụ nwere ihe nwere ike ime n'elu PTFE. Ebe ọ bụ na ụmụ irighiri ihe ndị a na-ekekọta abanyela n'ime oyi akwa molekul nke PTFE, imebi njikọ ahụ chọrọ mbibi intermolecular, na-ebute ike njikọ dị elu.

4. Ụzọ radieshon

A na-etinye PTFE na monomers polymerizable reactive dị ka styrene, fumaric acid, methacrylates na ndị ọzọ, wee tinye ya na Co-60 . Nke a na-akpalite polymer graft polymerization nke monomers n'elu PTFE, na-akpụ akwa polymer graft nke dị mfe ijikọ. Grafting na-emekwa ka elu ya dị njọ, na-eme ka mpaghara njikọ ahụ dịkwuo elu ma na-eme ka ike nke njikọ dịkwuo elu.

5. Nkà na ụzụ ọgwụgwọ Plasma

Ọgwụgwọ Plasma bụ otu n'ime teknụzụ na-emepe emepe ngwa ngwa maka mgbanwe elu elu PTFE n'afọ ndị na-adịbeghị anya.

Ihe kachasị mkpa nke teknụzụ a bụ itinye ihe nlele ahụ na ngwaọrụ ọgwụgwọ plasma raara onwe ya nye, ebe ion bombardment ma ọ bụ ntinye na-agbaji njikọ molecular ma ọ bụ na-ewebata otu ndị na-arụ ọrụ na elu polymer, na-arụ ọrụ elu iji nweta mgbanwe. Ions nwere ike ịbụ gas inert, gas na-arụ ọrụ nke kemịkal ma ọ bụ ihe ọla. Bọmbụ na gas inert nwere ike gbanwee nhazi elu nke polymer.

Ozi dị n'elu bụ Jiangsu Aokai New Materials Technology Co., Ltd.

Maka nkọwa zuru ezu, ọnọdụ ngwa na ngwọta ahaziri nke ngwaahịa anyị zuru oke - gụnyere akwa akwa okpomọkụ dị elu PTFE, teepu okpomọkụ dị elu PTFE, eriri akwa PTFE dị elu, eriri na-enweghị ihe ọ bụla maka igwe na-ejikọta, akwa PTFE nwere otu akụkụ, akwa okpomọkụ na-eguzogide ọgwụ na-ebufe eriri, akwa iko na-eguzogide ọgwụ, biko kpọtụrụ anyị.
