Indlela i-PTFE Tape Sika ngayo iSiphelo soBuso obuNxulumana neNto yokuncamathela kunye nokuPhakanyiswa koMphetho

Nini Iteyiphu ye-PTFE yobushushu obuphezulu isetyenziswa kwi-sealer yokushisa, i-roller yesikhokelo, okanye i-bonding surface, iingxaki ezimbini eziqhelekileyo zinokuvela emiphethweni: i-adhesive oozing (i-glue ephuma kwi-edge enqunyiweyo) kunye nokunyuswa komphetho (i-tape edge exobula kude ne-substrate).

Ezi ziphene zivame ukulandelwa kumthombo omnye: umgangatho wenkqubo yokuqhawula (ukusika). Isakhiwo sobuso besiphelo esinqunyiwe - nokuba sibushelelezi okanye sibuhlungu, sicocekile okanye sihlanjululwe - sinquma indlela i-adhesive eziphatha ngayo emphethweni.

I-Aokai PTFE ilawula umgangatho wokucanda ukunqanda le miba. Esi sikhokelo sicacisa ukuba isiphelo sobuso be-morphology sibangela njani ukukhupha kunye nokuphakamisa, kwaye ukuba umphetho wetape osikiwe ngokufanelekileyo kufuneka ujongeke njani.

Ubume be-PTFE Tape Cross-Section

Ukuze uqonde indlela isiphelo esisikiweyo esichaphazela ngayo ukusebenza, okokuqala khumbula isakhiwo se-tape. Iteyiphu ye-PTFE yobushushu obuphezulu ibandakanya:

• I-Fiberglass ilaphu substrate (ukuqinisa)

• I-PTFE yokwambathisa (umphezulu ongentonga)

• Umaleko wokuncamathelisa obuthathaka kuxinzelelo lweSilicone (icala elibondayo)

Ukusika kubhekiselele ekusikeni ngokude le composite elaminethiweyo ibe yimiqulu emincinci. I-morphology yobuso besiphelo esisikiweyo - egudileyo okanye erhabaxa, ethe tye okanye e-wavy - kunye ne-dimensional yesiqhelo (i-flatness, i-verticality, ukunqongophala kwe-adhesive okanye i-stringing) ibangela iziphene ezibini.

Indlela Ubuso obusikiweyo obubangela ukuba iAdhesive Oozing

Ukuncamathelisa okuncamathelayo kuthetha ukungena okungacetywanga kokuncamathelayo ukusuka kumphetho weteyiphu, ukungcolisa izixhobo zokusebenza ezidityanisiweyo okanye icala elingasemva leteyiphu. Ubuso obusikiweyo bunempembelelo ethe ngqo.

1. Ukutsala kunye nefuthe lentambo kwi-cut

Ukuba i-slitting blade iyancipha okanye i-angle yokusika ayifanelekanga, i-blade iya kutsala kwaye yolule i-silicone eguquguqukayo ye-PSA endaweni yokuyisika ngokucocekileyo. Oku kubangela:

• I-Microscopic glue filaments kunye ne-burrs: I-adhesive ekrazukileyo ishiya imisonto yeglue ecolekileyo kakhulu okanye iiflakes eziphuma kumphetho weteyiphu. Ezi 'i-glue whiskers' zigqithisa ngokulula kwaye zaphuka ngexesha lokucubungula okanye ukugcinwa, zenza umphumo wokubonwayo we-adhesive oozing.

• Ukufuduka okuncamathelayo ukuya emaphethelweni: Amandla okutsala ngexesha lokukrola arhuqa incamathelisa kwisiphelo sobuso kunye nakwicandelo elinqamlezayo le-substrate. Xa itheyiphu ifakwe kumqulu, i-adhesive extruded incamathela kwi-PTFE ngasemva koluhlu olusondeleyo. Emva kokukhulula, iglue eshiyekileyo ivela ecaleni kwencam-ukusilela kweklasikhi.

2. Isiphumo sokwandiswa kobuso obungalinganiyo

Ubuso obunesiphelo esinesiphelo esibi (umphezulu oguquguqukayo, iiprotrusions, iinqwelomoya ezithambekileyo) zinoxinzelelo olungaqhelekanga olusecaleni kwiindawo eziphakanyisiweyo xa itheyiphu isongelwe ngokuqinileyo ibe yimiqulu. I-Silicone PSA i-viscoelastic - ihamba phantsi koxinzelelo oluzinzileyo, ngakumbi ngexesha lokugcinwa kobushushu obuphezulu okanye ukuthutha. Olu xinzelelo luqhuba i-adhesive ukuba ihambe ukusuka kwi-high-pressure protrusions ukuya kwi-voids yoxinzelelo oluphantsi, ukukhupha ukusuka ekupheleni kobuso.

3. Isitywina somphetho esaphukileyo phakathi kwe-adhesive kunye ne-substrate

Ukunqunyulwa okufanelekileyo kuzisa indawo egungxulwayo enqamlezayo edibanisa zonke iileya. Ukunqunyulwa okungalunganga kunokubangela i-delamination kunye nokwahlula phakathi kwe-adhesive kunye ne-fiberglass, okanye imingxunya kumnqamlezo, ukwaphula isakhiwo somphetho esitywiniweyo. Xa ishushu, into encamathelayo ethambileyo iphumela ngaphandle ngala mijelo mincinci. Kumaqondo obushushu aphezulu (umzekelo, izitywini zobushushu ezingaphezulu kwama-200°C), ukuncamathela okumanzi okuncamathelayo, kunye nobuso oburhabaxa bunyusa kakhulu umngcipheko wokuphuma kwamanzi.

Indlela Ubuso obusikiweyo bubangela ukuphakanyiswa komda

Ukunyuswa komphetho kubhekiselele ekwahlukaneni okuzenzekelayo kwemiphetho yeteyiphu ukusuka kwindawo edityanisiweyo phantsi koxinzelelo okanye ubushushu emva kokufakwa kwesicelo.

1. Umaleko wokuncamathelisa ocekethekileyo - indawo edibeneyo ebuthathaka

Amacwecwe anqabileyo okanye iiparitha ezingafanelekanga zokuqhawula zivelisa umphumo wokunciphisa ukunyanzeliswa: i-blade icinezela izinto eziphathekayo ngaphandle kokuyicoca ngokucocekileyo. I-Adhesive iqukuqela ecaleni phantsi koxinzelelo, nto leyo ekhokelela kuncamatheliso olubhityileyo okanye olulahlekileyo kumda ongaphandle. Lo mmandla usemda unamandla okubopha asezantsi kakhulu kunomzimba weteyiphu, ngoko ke ukuphakanyiswa komphetho kuqalisa apha phantsi koxinzelelo oluncinci okanye uxinzelelo lobushushu.

2. I-substrate burrs kunye ne-delamination - isiphumo somtshato

I-PTFE tape substrate iqulethe ifayibha yeglasi. Ukuqhawula okungafanelekanga kukhupha iifilaments ze-fiberglass endaweni yokuzisika ngokucocekileyo, kushiya i-fiberglass burrs eqinile ebusweni bokugqibela. Ngexesha le-lamination, la ma-burrs aqinileyo axhasa i-tape edge, enza izithuba ezincinci phakathi kwendawo yokuncamathelisa kunye ne-workpiece - ethintela uqhagamshelwano olupheleleyo kunye nokuphakamisa.

Ukuba ukucandwa kubangela i-delamination phakathi kwe-PTFE yokwambathisa kunye ne-fiberglass emiphethweni, amazinga okwanda kwe-thermal angahambelaniyo avelisa uxinzelelo lwangaphakathi emva kokufudumeza, ukuxobula imiphetho ngokuthe ngqo kude nama-substrates.

3. I-Serrated okanye i-notched edges-concentration concentration

Ii-serrations ezibonakalayo kunye neenotshi zibamba umoya kwaye zithintele ukudibana komphezulu ogcweleyo emva kokubambana. Nditsho nemiphetho ethe tyaba ye-macroscopically ene-micro-unevenness engalinganiyo yokwandiswa kwe-thermal xa ishushu, ikrazula i-bonding interface kwaye ibangela ukuphakanyiswa komphetho we-cascading.

4. Ukungcola kwi-adhesive extruded - ukunciphisa i-edge tack

I-adhesive ene-oozed engqongqo inokuphinda ibambelele kwi-tape ekupheleni, iguqule iimpawu zekhemikhali zomaleko we-adhesive marginal. Landela amabala e-oyile akhutshelwe ukusuka kwiincakuba nako ukunyathela okusezantsi komphetho - zonke zisebenza njengezinto zokuphakamisa.

IiMfuno eziMgangatho zoBuso obuMgangatho-UThintelwa njani i-Oozing kunye nokuPhakamisa

Ukucinezela i-adhesive ozing kunye nokunyusa umphetho ngokusisiseko, isiphelo sobuso sokuqhawula kufuneka sihlangabezane nezi ndlela zilandelayo:

1. I-Morphology - igudile kwaye iyagungxula

• Iintsinga zeglasi zisikwe ngokucocekileyo ngaphandle kokuvezwa.

• Umaleko wokuncamathelisa, i-substrate, kunye ne-PTFE yokwambathisa yenza icandelo elisicaba elidibeneyo.

• Akukho ntambo yeglue, ukunqongophala kokuncamathelisa, okanye i-delamination.

2. Ukunyaniseka - ngokuthe ngqo kunye nokufana

• Ubuso besiphelo esithe tye obunokukhanya okuncinci kunye nokuthambekela.

• Iqinisekisa ukuhanjiswa okufanayo koxinzelelo xa ifakwe kwimiqulu.

Ubuso obugudileyo, obungenakonakala busebenza 'njengetywina' kwiincam zeteyiphu. Itshixa umaleko wokuncamathelisa ngokuchasene nokufuduka okunyakazelayo kwaye iqinisekisa umthamo opheleleyo wokuhlangana kunye ne-millimeter nganye yomphetho-ukuphelisa ukugobhoza kunye nokuphakamisa emthonjeni.

Isishwankathelo - Umgangatho wokuSlitting uchaphazela ngokuthe ngqo ukusebenza kweTape

I-Aokai PTFE isebenzisa izixhobo zokucheba ezichanekileyo ezinencakuba ezibukhali kunye nee-engile eziphuculweyo ukuvelisa iincam zeteyiphu ezicocekileyo, ezigudileyo, nezingenaziphene. Ukuba ujongene ne-edge okanye uphakanyiswa ngezinye iiteyiphu, umgangatho wokusika unokuba ngunobangela. Qhagamshelana nathi ukuxoxa ngesicelo sakho.
