Yuav ua li cas los txhim kho cov nyhuv Lamination ntawm PTFE High Temperature Daim kab xev ntawm Curved Surfaces

Raws li cov kws tshaj lij kev lag luam ntawm PTFE cov ntaub ntawv kub kub, Jiangsu Aokai Cov Khoom Tshiab muab cov tswv yim daws teeb meem nrog koj.

Txhawm rau thov PTFE daim kab xev kub kub ruaj khov rau ntawm qhov nkhaus thiab qhov tsis sib xws yam tsis muaj npuas thiab ntug warping, txheej txheem kev ua haujlwm yog qhov tseem ceeb, suav nrog kev ua kom zoo hauv substrate pretreatment, kev tshaj lij daim ntawv thov thiab kev ntsuas kom raug. Ntawm lawv, substrate pretreatment yog cov kauj ruam tseem ceeb tshaj plaws, uas txiav txim siab txog 70% ntawm qhov kawg ntawm cov nyhuv.

1. Kev npaj txaus substrate

●  Kev tu kom huv : So cov khoom sib txuas kom tiav nrog cov dej tsis huv ethanol lossis acetone kom tshem tawm cov roj stains, plua plav thiab impurities. Tsis txhob siv roj av thiab lwm cov kuab tshuaj uas ua rau cov roj seem.

●  Kev xuab zeb kom zoo : Maj mam txhuam cov npoo du nrog 240-320 grit zoo sandpaper los tsim cov micro ntxhib ntxhib ntxhib ntxhib los mos, thiaj li ua rau thaj chaw sib cuag thiab cov khoom siv adhesion. Ntxuav tag nrho cov plua plav kom huv si tom qab polishing.

●  Ib puag ncig & tswj qhov kub thiab txias : Khaws ib puag ncig kev tsim kho kom qhuav thiab tsis muaj plua plav nrog kev ua haujlwm kub ntawm 15 ℃ txog 40 ℃. Kub hauv qab 10 ℃ yuav txo tau qhov pib tackiness zoo heev thiab ua rau tsis zoo adhesion.

2. Cov txheej txheem thov kom raug

●  Xaiv cov kab xev uas tsim nyog : Ua ntej daim kab xev cim nrog cov nplaum nplaum thiab siab ductility, uas haum rau qhov chaw nkhaus zoo dua. Xaiv silicone siab-rhiab nplaum daim kab xev rau kev pab mus ntev txog 260 ℃. Vim yog lub zog qis ntawm cov khoom PTFE, cov kab xev zoo tib yam yog ib qho nyuaj rau lo stably. Nws raug nquahu kom xaiv cov kab xev nrog cov tshuaj etched lossis plasma-kho cov nplaum sab. Cov pab pawg ua haujlwm ntawm qhov chaw kho mob tuaj yeem tsim kev sib raug zoo zog thiab tiv thaiv kev nqa ntug.

●  Preheat daim kab xev (yeem) : Preheat daim kab xev luv luv hauv qab 60 ℃ nrog lub tshuab ziab plaub hau los txhim kho qhov pib viscosity thiab fluidity ntawm cov nplaum, ua tiav cov nyhuv ntub dej zoo dua ntawm qhov tsis sib xws thiab nkhaus.

●  Segmented sticking method : Tsis txhob tev tawm tag nrho cov liner tso tawm ib zaug. Kho ib qho kawg lossis qhov chaw nruab nrab ua ntej, tom qab ntawd tev lub liner ib kauj ruam thiab muab cov kab xev los ntawm ntu (5-10cm ib ntu) raws li qhov chaw radian.

●  Txoj kev khiav tawm ntawm huab cua : Siv silicone roller los yog scraper los nias qhov sib npaug ntawm qhov chaw mus rau ob sab thiab los ntawm qhov chaw sib txuas mus rau qhov chaw tsis muaj kev sib txuas kom nyem tawm cov cua nkag tag.

3. Kev Pabcuam Pabcuam Tswvcuab

●  Thermal shaping & compaction : Tom qab ua ntej pasting, ua kom sov daim kab xev sib npaug nrog cov phom cua kub kom qhib cov nplaum thiab txhim kho nws cov fluidity rau tag nrho cov nto ntub dej. Yob thiab nias ruaj khov thaum kub, tshwj xeeb tshaj yog ntawm cov npoo. Cov kauj ruam no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov ntaub nplaum tuab saum 0.18mm.

●  Tiv thaiv ntug warping nruj me ntsis : Tsis txhob ncab daim kab xev thaum lub sij hawm thov, vim rebound quab yuam yog lub ntsiab ua rau ntawm ntug lifting. Khaws qhov sib tshooj dav dua 20mm kom zoo sealing nyhuv. Rov ua kom tag nrho cov npoo nrog scraper. Cia nws sawv ntawm chav sov li 24 mus rau 48 teev kom ua tiav cov nplaum ua kom zoo thiab ua kom lub zog zoo. Rau siab dua ntug firmness, thov ib tug me me ntawm high temperature resistant silicone sealant rau kev txhawb zog.

●  Kev daws teeb meem : Yog tias me ntsis ntug warping tshwm sim tom qab daim ntawv thov, ua kom sov qhov chaw warped hauv zos nrog rab phom cua kub thiab rov ua kom nruj kom kho.
