Cooling Rate Effects ho PTFE Tape

Joaloka moetsi oa pele oa litheipi tsa mocheso o phahameng oa PTFE, Jiangsu Aokai New Materials ka mona e hlakisa litlamorao tsa mekhoa ea ho pholisa le litekanyetso tsa ho pholisa tšebetsong ea litheipi tse phekotsoeng tsa PTFE.

I. Essence of PTFE Crystallization Characters and Cooling Rate Regulation

The PTFE substrate ea theipi e phekotsoeng ea mocheso o phahameng ke ea semi-crystalline polymer, e kenang ka potlako crystallization nakong ea pholileng ka mor'a ho sintering. Ha e le hantle, sekhahla sa ho pholisa ke parameter ea mantlha ea ts'ebetso ea ho laola crystallinity ea tepi ea mocheso o phahameng oa PTFE: ho pholile butle ho lebisa ho crystallinity e phahameng, ha ho pholisa ka potlako ho fella ka crystallinity e tlaase.

II. Liphello tsa ho Pholisa butle ho PTFE Litheipi tsa mocheso o phahameng oa mocheso

Tšusumetso ho Khatello ea ka Hare  Ho pholisa butle ho ka fokotsa ka nepo khatello e setseng ea mocheso kahare ho theipi. Ha tepi e pholile ka tlhaho ka har'a sebōpi, matrix a PTFE le khalase ea fiber skeleton e na le nako e lekaneng ea ho fetola liphapang tsa shrinkage ka ho phomola ketane ea limolek'hule, ho qoba khatello ea kelello ea sebakeng seo.

Mokhoa o amohetsoeng ka bongata ke oa ho pholisa theipi ka tlhaho ka seboping ho isa ho 150–200℃ pele o e ntša bakeng sa ho pholisa moea. Ts'ebetso ena e liehang ea ho pholisa e fokotsa khatello ea kelello ea ka hare ka katleho 'me e thibela ho roala delamination le ho phunyeha.

Tšusumetso ho Dimensional Stability  Ho tsidifala butle ho ntlafatsa haholo botsitso ba dimensional. Nakong ea ho pholile butle, liketane tsa PTFE tsa limolek'hule li hlophisa li-lattices tse tloaelehileng tsa kristale ka mokhoa o lekaneng, ho etsa kristale e phahameng le lithollo tsa kristale tse ntlafalitsoeng hantle, tse tiisang hore litekanyo tsa ho qetela tse tsitsitseng.

Ho fokotseha ho honyenyane ha mocheso ho tla etsahala tlas'a mocheso o phahameng ha o sebelisoa, kahoo ho kgothaletswa ho boloka 1% -2% margin nakong ea kopo. Ho pholisa butle ho thusa ho honyela ho sa feleng ka ho senyeha ho fokolang ha masala.

Tšusumetso ho Ts'ebetso ea Sekhomaretsi  Ho pholisa butle ho na le litlamorao tse peli ho thepa ea ho khomarela. Ka lehlakoreng le leng, e lumella lera la sekhomaretsi hore le qete ho hokahanya le ho phomola ha khatello ea kelello ka botlalo, ho boloka matla a tsitsitseng a ho kopanya. Ka lehlakoreng le leng, kristale e phahameng e eketsa ho tiea ha bokaholimo ba PTFE substrate, ho baka khatello e matla holim'a sehokelo sa bonding tlas'a matla a peeling.

III. Liphello tsa ho Pholisa ka Potlako ho Litheipi tsa PTFE tsa mocheso o phahameng

     Tšusumetso ho Khatello ea Ka Hare  Ho phola ka potlako ke sesosa se ka sehloohong sa khatello e feteletseng ea ka hare. Ho tima ka ho toba ka mor'a ho chesa ho baka phapang e kholo ea mocheso pakeng tsa PTFE matrix le khalase ea fiber framework, ho hlahisa khatello ea kelello hang-hang le ho etsa mapetsong a matle habonolo.

Lera le ka holimo le fokotseha le ho thatafala ka potlako ha lesela le ka hare le ntse le atolosoa, le etsa boemo ba khatello ea mocheso ea khatello ea ka ntle le khatello ea ka hare, e bakang ka ho toba ho phunyeha ha theipi.

Tšusumetso ho Dimensional Stability  Ho pholisa ka potlako ho fetola tlhoro ea kristale ho theola mocheso le ho fokotsa khanya ka sebopeho sa kristale se sa fellang. Theipi e lula sebakeng sa leqhoa se sa leka-lekaneng ka mor'a ho tima. crystallization ea bobeli le post-shrinkage li ka etsahala tlas'a liphetoho tse latelang tsa mocheso, tse lebisang ho kheloha butle-butle.

Tšusumetso ho Ts'ebetso ea Sekhomaretsi  Ho pholile ka potlako ho thibela khokahano e felletseng ea likarolo tsa sekhomaretsi. Sekhomaretsi se hoamisoa pele se theha marang-rang a hokahaneng a felletseng, e leng se bakang ho fokotseha ha matla a tlamahano le ho hanyetsa mocheso.

Tlas'a libaesekele tse batang le tse chesang khafetsa, phapang ea katoloso ea mocheso lipakeng tsa PTFE substrate le sekhomaretsi se hlahisa khatello ea maikutlo, e potlakisa botsofali ba sekhomaretsi, 'me e fokolisa haholo ho tšoarella ha viscosity.

IV. Papiso ea Mekhoa e sa Tšoaneng ea ho Pholisa

 

Ka kakaretso, ho pholisa butle le ho ts'oana ke molao-motheo oa motheo bakeng sa phekolo ea morao-rao ea litheipi tsa PTFE tse phahameng tsa mocheso. Ho kgothaletswa ho amohela pholileng ea tlhaho ka seboping ka mor'a ho chesa, 'me u ntše litheipi bakeng sa ho pholisa moea ho mocheso oa kamore ka mor'a hore mocheso o theohele ka tlase ho 150-200 ℃. Pholiso e sa tsitsang nakong ea tlhahiso e tla baka ho khoehlisa 'me qetellong e senye boleng ba sehlahisoa.
