Amaqonga aselunxwemeni, iinqanawa, iiinjini zomoya eziselunxwemeni, kunye nezixhobo zobunjineli zaselwandle zijongene notshaba olungayekeleliyo: isitshizi setyuwa . Igqwalisa iintsimbi, yonakalise izinto ezincamathelayo, kwaye yenza bufutshane ubomi besixhobo. Ngaba PTFE high-ubushushu tape ukusinda kwezi meko zinzima?
Impendulo emfutshane: i-PTFE substrate ngokwayo ayinakonakala kwisitshizi setyuwa. Kodwa ukusebenza ngokubanzi kweteyiphu kuxhomekeke kakhulu kuhlobo lokuncamathelisa kunye nomgangatho wofakelo.
I-Aokai PTFE ibonelele ngeeteyiphu ze-PTFE zezicelo zaselwandle iminyaka. Eli nqaku lichaza ukuxhathisa kwetyuwa yokutshiza, ukukhetha ukunamathela, ukulungiswa kwendawo, ukutywinwa komphetho, kunye nokugcinwa - ukuze ukwazi ukufezekisa ukuthembeka kwexesha elide kwiindawo eziselunxwemeni naselwandle.
Ukunyangwa kwesitshizi seTyuwa – PTFE Substrate vs. Adhesive
1. I-PTFE Substrate – Ayinyangeki ngokupheleleyo
I-PTFE ibonisa ukunganyaniseki kweekhemikhali okubalaseleyo. Ayinakusebenza ngokugqibeleleyo ngamanzi olwandle kunye nesitshizi setyuwa, kunye nesantya sokufunxa amanzi ngaphantsi kwe -0.01% . Ikwabonelela ngeUV ebalaseleyo kunye nokumelana nemozulu. I-PTFE substrate ngokwayo iyaxhathisa ngokupheleleyo kwisitshizi setyuwa – akukho mhlwa, ukuthotywa, okanye ilahleko yeempawu ezibonakalayo.
Idatha ephambili: I-PTFE ayibonisi tshintsho lobunzima obunokulinganiswa okanye ukuthotywa komphezulu emva kwamawaka eeyure kumagumbi okutshiza ngetyuwa.
2. I-Adhesive - Ikhonkco elibuthathaka
Ukuchasana kokutshizwa kwetyuwa ngokubanzi kwiteyiphu kuxhomekeke ikakhulu kuhlobo lokuncamathelisa:
Uhlobo oluncamathelayo |
Ukunyangwa kweSitshizi seTyuwa |
Ukufaneleka kwabaseLwandle |
I-Silicone PSA |
Okugqwesileyo - ukumelana ne-500-1000 + iiyure ezingathathi hlangothi zovavanyo lokutshiza ityuwa; Ukugcina amandla e-peel>80% |
✅ Ukhetho olukhethiweyo |
Acrylic PSA |
Imbi-i-hydrolysis, ukufuduka kwe-plasticizer, ilahleko enkulu yokubambelela phantsi kobushushu obuphezulu / ukufuma / isitshizi setyuwa |
❌ Ayikhuthazwa |
Kutheni i-silicone iphumelela: Inkqubo ye-silicone edityanisiweyo ngokunqamlezileyo ingokwemvelo i-hydrophobic, i-UV-resistant, kwaye izinzile ukunqumla -70°C ukuya kuma-260°C. Igcina ukubambelela kunye nokuguquguquka nasemva kokuvezwa kokutshiza kwetyuwa ixesha elide.
Kutheni i-acrylic isilela: I-adhesives ye-acrylic eqhelekileyo idlula i-hydrolysis kwiindawo eziphakamileyo zokufuma. Isitshizi setyuwa sikhawulezisa ukuwohloka kwamabhondi e-ester, okukhokelela ekuthomalaliseni okuncamathelayo, ukufuduka, kunye nokusilela kwebhondi ekugqibeleni.
I-Aokai PTFE isebenzisa kuphela i-silicone ye-PSA esebenza kakhulu kwiiteyiphu zethu ze-PTFE zodidi lwaselwandle. Siye saqinisekisa iiteyiphu zethu ngovavanyo oluzimeleyo lwe-1000 yeyure engathathi hlangothi yokutshiza ityuwa nge> 80% ukugcinwa kwamandla e-peel - amaxwebhu akhoyo xa eceliwe.
IiMfuno zokuSebenza kwiNdawo yokuSingqongileyo yaseLwandle nokuPhakamileyo kweTyuwa
Ukufumana inkonzo ethembekileyo kumaqonga onxweme, iinqanawa, izibonelelo zamandla omoya onxweme, kunye nezixhobo zobunjineli zaselwandle, inkqubo epheleleyo yolawulo olugqumayo ukukhetha izinto, ukwakhiwa, ukuyila kunye nokugcinwa kuyadingeka.
1. Ukukhethwa kwezinto
Imfuneko |
Inkcazo |
Ukuncamathelisa |
I-silicone-based, ukumelana nobushushu ≥260 °C, ixesha elide ukumelana nokufuma okuphezulu, isitshizi setyuwa, kunye ne-UV. |
ISubstrate |
Ifilimu ecocekileyo ye-PTFE okanye umgangatho ophezulu we-PTFE-ilaphu le-fiberglass efakwe kwi-fiberglass-amandla aphezulu omatshini, ukungena okuncinci, ukuguquguquka kwemozulu. |
Ukufakwa kokufakelwa kombane |
Khetha ubukhulu beteyiphu ngokwenqanaba lombane; jonga umgama wokukrazula ukuthintela ukuqhekeka komhlaba phantsi kwesitshizi setyuwa kunye neemeko ezifumileyo |
2. Unyango loMphezulu
Susa ngokucokisekileyo ioli, ityuwa, kunye nomhlwa kwindawo edibeneyo. Qinisekisa ukuba umphezulu womile ngokupheleleyo.
Sula ngokuphindaphindiweyo nge-ethanol ye-anhydrous okanye i-acetone de kungabikho ungcoliseko oluseleyo.
Kumphezulu wentsimbi: Iyacetyiswa ukuba ibe rhabaxa ngokuqhunyiswa kwesanti okanye ukugalela isanti (80-120 grit) ukunyusa amandla omatshini we-ankile.
Kwiimeko ezinzima kakhulu: Faka isicelo se-silicone primer ukongeza - kuphucula kakhulu ukunamathela kokuqala kunye nokuxhatshazwa kwexesha elide lokutshiza ityuwa kwiindawo zetsimbi.
Kutheni le nto ibalulekile: I-tape-substrate interface yeyona ndawo ibuthathaka kwiindawo zokutshiza ityuwa. Unyango olungonelanga lomphezulu luvumela isitshizi setyuwa ukuba singene ecaleni kwe-interface, ebangela ukubola kwe-metal substrates okanye i-delamination ye-adhesive layer.
3. Inkqubo yokwakha
Inyathelo |
Imfuneko |
Ngoba |
Iimeko zokusingqongileyo |
Ubushushu be-Ambient ≥10 °C, ukufuma okuhlobene ≤75%. Musa ukusebenzisa kwindawo enombethe okanye emanzi |
Ikhusela ukuxinana phantsi kwetape |
Ukupheliswa kweqamza lomoya |
Roll okanye itheyiphu egudileyo ngokupheleleyo emva kwesicelo ukukhupha onke amaqamza omoya |
Iqinisekisa i-100% yoqhagamshelwano oluluqilima, akukho zikhewu zokutshiza ityuwa ziqokelelane |
Ububanzi beLap |
≥10–15 mm. Faka uxinzelelo olongezelelweyo kwiindawo eziwelanayo. Ngokuzikhethela, thambisa i-adhesive ngomoya oshushu osezantsi ngaphambi kokucinezela |
Yandisa ukutywinwa kwiindawo ezidityanisiweyo |
Ukutywinwa komda (kubalulekile elwandle) |
Yambathisa yonke imiphetho eveziweyo nge -silicone ekwazi ukumelana nemozulu |
Iibhloko zokungeniswa kwesitshizi setyuwa ecaleni kwemida yokujongana - elona nyathelo libalulekileyo lokuthembeka kwexesha elide |
4. Uyilo kunye neMigaqo yokuKhetha
Ububanzi beTape - Kuya kuba bukhulu kunommandla okhuselweyo, ukugcina umda wokutywina opheleleyo ubuncinane ubuncinane be-5-10 mm kwicala ngalinye.
Ukwandiswa kwe-Thermal - Ukunikezelwa kweenguqu ezinzulu zobushushu phakathi kweendawo ezikhanyiswe ilanga / ezinomthunzi kunye nemini / nobusuku, khetha iiteyiphu ezinokuguquguquka okulungileyo kunye nokuhambelana nokuphepha ukuboleka kwibhayisikile eshushu.
I-Electrochemical corrosion - Xa isetyenziswe kwiinkqubo zokukhusela i-cathodic okanye i-joints of metals dissimilar, qinisekisa ukuba i-tape inokumelana nokukhusela okuphezulu okwaneleyo ukuphepha ukubola kwe-galvanic.

Ngokusekwe kumava entsimi - musa ukulinda ukusilela okubonakalayo |
Isishwankathelo , iteyiphu yobushushu obuphezulu ye-PTFE ilunge ngokwendalo kwindawo yokutshiza ityuwa yaselwandle kunye nephezulu - i-PTFE substrate imelana netyuwa, i-UV, kunye nokufuma ngokugqibeleleyo. Nangona kunjalo, ukuthembeka kwexesha elide le-tape kuxhomekeke kwi-adhesive. I-Silicone PSA iyona kuphela ekhethwayo kwizicelo zase-offshore kunye nonxweme, kunye ne-500-1000+ eqinisekisiweyo yeyure yokusebenza yokuvavanya ityuwa yokutshiza ityuwa (>80% ukugcinwa kwe-peel). I-Acrylic PSA iya kusilela kwisithuba seenyanga.
Ngaphandle kokhetho oluncamathelayo, impumelelo ifuna ukucocwa ngokucokisekileyo komphezulu kunye nokurhabaxa, usetyenziso olungenagwebu, kwaye-okubaluleke kakhulu - ukutywinwa komphetho nge-silicone sealant ukuthintela ukungena kwesitshizi setyuwa. Ukuhlolwa rhoqo kunye nokutshintshwa okucwangcisiweyo kugqibezela isicwangciso sokuthembeka.
