Mmetụta dị jụụ na teepu PTFE

Dị ka onye mbụ emeputa nke PTFE elu-okpomọkụ teepu, Jiangsu Aokai New Materials ugbu a elaborates mmetụta nke jụrụ ụzọ na jụrụ ọnụego na arụmọrụ nke gwọrọ PTFE elu-okpomọkụ teepu.

I. Ihe kachasi mkpa nke PTFE Crystallization Characterities and Cooling Rate Regulation

Mpempe PTFE nke teepu okpomọkụ a gwọrọ agwọ bụ nke polymer-crystalline, nke na-eme ngwa ngwa crystallization n'oge jụrụ oyi mgbe ọ gbasasịrị. N'ụzọ bụ isi, ọnụego jụrụ oyi bụ isi usoro usoro iji chịkwaa kristal nke teepu okpomọkụ dị elu nke PTFE: iji nwayọ nwayọ na-eduga na kristal dị elu, ebe ngwa ngwa jụrụ oyi na-ebute kristal dị ala.

II. Mmetụta nke ịdị nwayọọ nwayọọ na teepu PTFE dị elu

Mmetụta dị na mgbakasị obi dị n'ime ime  ka ọ dị jụụ nwere ike belata nrụgide okpomọkụ fọdụrụnụ nke ọma n'ime teepu. Mgbe teepu na-ajụkwa ndammana n'ime ọkụ, PTFE matrix na iko eriri skeleton nwere oge zuru ezu iji dozie shrinkage iche iche site molekụla yinye ntụrụndụ, na-ezere mpaghara nchegbu itinye uche.

Usoro a nakweere n'ọtụtụ ebe bụ iji mee ka teepu ahụ dị jụụ n'ime ọkụ ruo 150-200 ℃ tupu ebupụ ya maka ikuku jụrụ oyi. Usoro a na-ajụ oyi nwayọ nwayọ na-ebelata nchekasị dị n'ime nke ọma ma na-egbochi mkpuchi mkpuchi na mgbawa.

Mmetụta na Dimensional Stability  Slow jụrụ oyi na-eme ka nkwụsi ike nke akụkụ dị ukwuu. N'oge nwayọ nwayọ, ụdọ molekụla PTFE na-ahazi n'ime lattices kristal oge niile, na-akpụ kristal dị elu na ọka kristal mepere emepe nke ọma, nke na-eme ka akụkụ ikpeazụ kwụsie ike.

Obere okpomọkụ ga-eme n'okpuru okpomọkụ dị elu na-eji ya eme ihe, ya mere a na-atụ aro idobe oke 1%-2% n'oge ngwa. Ịdị nwayọọ nwayọọ na-enyere mbelata nke ukwuu na nrụrụ dị ntakịrị.

Mmetụta na arụmọrụ nrapado  ngwa ngwa jụrụ oyi na-egosipụta mmetụta abụọ na ngwongwo adhesion. N'otu aka, ọ na-enye ohere ka oyi akwa nrapado mezue njikọ na-agafe agafe na izu ike nke nrụgide, na-ejigide ike njikọ kwụsiri ike. N'aka nke ọzọ, kristal dị elu na-abawanye nkwụsi ike nke mkpụrụ PTFE, na-akpata nrụgide gbadoro anya na njikọta njikọ n'okpuru ike peeling.

III. Mmetụta nke ịdị jụụ ngwa ngwa na teepu okpomọkụ dị elu PTFE

     Mmetụta na nrụgide dị n'ime  ime ka ọ dị jụụ ngwa ngwa bụ isi ihe na-akpata oke nrụgide dị n'ime. Direct quenching mgbe sintering emepụta nnukwu okpomọkụ dị iche n'etiti PTFE matrix na iko eriri kpuchie, na-amụ ozugbo shrinkage nchegbu na mfe akpụ ezi cracks.

N'elu oyi akwa na-adaba ma na-esi ike ngwa ngwa ka oyi akwa dị n'ime na-anọgide na-agbasawanye, na-eme ka ọnọdụ nrụgide okpomọkụ nke elu na mkpakọ dị n'ime, nke na-ebute mgbawa teepu ozugbo.

Mmetụta na Dimensional Stability  Njụjụ ngwa ngwa na-agbanwe ọnụ ọgụgụ kristal na-ebelata okpomọkụ ma na-ebelata kristal na nhazi kristal na-ezughị ezu. Teepu ahụ na-anọ n'ọnọdụ kpọnwụrụ akpọnwụ na-enweghị nha nha ka emenyụchara. Kristalaịza nke abụọ na mwepu ga-esochi nwere ike ime n'okpuru mgbanwe okpomọkụ na-esote, na-eduga n'ichepụta nwayọ nwayọ.

Mmetụta na arụmọrụ nrapado  ngwa ngwa jụrụ oyi na-egbochi njikọ nchikota nke akwa nrapado. Ihe nrapado na-ajụ oyi tupu ọ mepụta netwọk nwere njikọ gafee, na-ebute mbelata ike njikọ na nguzogide okpomọkụ.

N'okpuru ịnya igwe oyi na nke na-ekpo ọkụ ugboro ugboro, ọdịiche mgbasawanye okpomọkụ dị n'etiti mkpụrụ PTFE na akwa nrapado na-emepụta nrụgide interfacial, na-eme ka nrapado na-eme agadi na debonding, na-ebelata ike viscosity ogologo oge.

IV. Ntụle nke ụzọ oyi dị iche iche

 

N'ozuzu, ngwa ngwa na otu jụrụ oyi bụ ụkpụrụ bụ isi maka ọgwụgwọ ọgwụgwọ PTFE dị elu nke teepu okpomọkụ. A na-atụ aro ka ị na-ekpo ọkụ n'ime ọkụ ọkụ mgbe emechara ya, wee wepụ teepu ahụ maka ikuku jụrụ oyi na ụlọ okpomọkụ mgbe okpomọkụ dara n'okpuru 150-200 ℃. Ịjụ oyi na-enweghị isi n'oge mmepụta ga-eme ka ike gwụ ma mebie àgwà ngwaahịa.
