I-PTFE Tape Ukunyangwa kwesitshizi seTyuwa kunye neeMfuno zeSicelo saseLwandle

Iteyiphu ye-PTFE yobushushu obuphezulu isetyenziswa kakhulu kwimo engqongileyo yaselwandle - kumaqonga angaphesheya konxweme, iinqanawa, iiinjini zomoya eziselunxwemeni, kunye nemimandla yemizi-mveliso enetyuwa. I-PTFE yokwambathisa ngokwayo iyaxhathisa kakhulu kwisitshizi setyuwa. Nangona kunjalo, ukusebenza kweteyiphu iyonke kuxhomekeke kumanqaku amabini abuthathaka: umaleko wokuncamathelisa kunye nemiphetho ye-fiberglass substrate..

Isitshizi setyuwa sinokungena ngonxibelelwano oluncamathelayo okanye intambo kwimiphetho yefiberglass evelileyo, ibangele ukulahleka kokuncamatheliswa okanye ukuhlwa kwesubstrate. Ke ngoko, ukuvavanya ukumelana nokutshizwa kwetyuwa kuthetha ukuvavanya ukuba i-adhesive igcina amandla okubopha, iyamelana nokufunxwa kwamanzi, kwaye ikhusela intsimbi engaphantsi.

I-Aokai PTFE yenza iteyiphu ye-PTFE eqinisekisiweyo kwinkonzo yaselwandle. Esi sikhokelo sichaza iindlela zovavanyo olusemgangathweni, iindlela zokwamkelwa, kunye neemfuno zesicelo kwindawo enetyuwa ephezulu.

Iindlela zoVavanyo lwesitshizi seTyuwa kwiTape ye-PTFE

Uvavanyo olusemgangathweni luqinisekisa ukuba iteyiphu ihlangabezana nokuqina komgangatho waselwandle. Eyona ndlela ixhaphakileyo sisitshizi setyuwa engathathi hlangothi (NSS) ngokwe-ISO 9227 okanye i-ASTM B117.

1. Ukulungiselela isampuli

1. Laminate itheyiphu ye-PTFE kwipaneli yovavanyo lwentsimbi eqhelekileyo (umzekelo, i-SUS304 intsimbi engatyiwayo okanye i-substrate ecetywayo) usebenzisa irola.

2. Vala imiphetho yeteyiphu ngesitywina esingangeni manzi ukuthintela ukungena kwenkungu yetyuwa engaqhelekanga kwincam esikiweyo. Oku kulinganisa ukufakela okufanelekileyo apho imiphetho ikhuselweyo.

3. Lungiselela imizekelo eyaneleyo yovavanyo lwangaphambili, uvavanyo lwasemva, kunye namaqela olawulo.

2. Ukubonakaliswa kwenkungu yetyuwa

• Beka iisampuli kwindawo yokutshiza ityuwa kwi-35 ° C, i-5% yesisombululo se-NaCl.

• Ubude bexesha lovavanyo: 96h, 240h, 500h, 1000h , okanye njengoko kuvunyelwene.

• Iiphaneli zovavanyo tyekethisa kwi-15°–30° ukusuka nkqo ukuze kubekho inkungu yetyuwa.

3. Uvavanyo emva kokuba sesichengeni (hlanjululwa kwaye womise)

IiMfuno zesicelo kwiNdawo yaseLwandle kunye neNkungu ePhezulu-yeTyuwa

Kusetyenziso lwehlabathi lokwenyani kumaqonga angaphesheya kolwandle, iinqanawa, amaziko ombane omoya aselunxwemeni, kunye nemimandla yemizi-mveliso enenkungu yetyuwa ephezulu, iteyiphu ye-PTFE kufuneka ihlangabezane neendlela ezingqongqo.

1. I-Adhesive - i-silicone ye-PSA inyanzelekile

• Isincamathelisi esinoxinzelelo lwe-silicone: Ukufunxa ukufuma okuphantsi kakhulu, ukuxhathisa okugqwesileyo kwenkungu yetyuwa, ubume bemozulu. Igcina amandla okudibanisa ixesha elide kwaye ayigqwali intsimbi engatyiwayo.

• I-Acrylic PSA-AYIFANELEKILEYO: I-hydrolyzes ngokulula, iplastiki, kwaye ilahlekelwe ukunamathela phantsi kobushushu obuphezulu kunye nenkungu yetyuwa enzima. I-Acrylic akufanele isetyenziswe kwiindawo zaselwandle.

2. I-Substrate kunye nokukhuselwa komda

• Ilaphu le-fiberglass kufuneka lifakwe ngokupheleleyo nge-PTFE , lingabi namingxuma. Oku kuthintela ukungena kwetyuwa ngesenzo se-capillary ecaleni kwemicu, enokubangela ukuba i-delamination.

• Ngexesha lofakelo, i-tape yokutywina idibanisa kunye nemiphetho ene-sealant yokumelana nemozulu ezinikeleyo (umzekelo, i-silicone-based). Oku kuthintela iindlela zokungena kwinkungu yetyuwa - elona nyathelo libalulekileyo lokuthembeka kwexesha elide.

3. Izalathi ezicetyiswayo zokuxhathisa isitshizi setyuwa

• Ubuncinci be-1000h engathathi hlangothi isitshizi setyuwa (NSS) ngaphandle kokunyuswa okuzenzekelayo okanye ukugqabhuka.

• I-180 ° ukugcinwa kwamandla e-peel ≥80% emva kwe-1000h.

• Akukho mhlwa kwintsimbi engaphantsi (okanye i-corrosion traces kwimida ekuvunyelwene ngayo).

• Kwiimeko ezimaxongo ngokugqithisileyo (umzekelo, imimandla yolwandle eneatmosferi enemijikelo yokumanzisa okomileyo), 2000h NSS okanye uvavanyo lwe-cyclic corrosion (CCT) luyacetyiswa.

4. Ukuziqhelanisa neemeko ezidibeneyo

• Ubushushu obuphezulu + nenkungu yetyuwa: Ukuvala umbhobho wokukhupha okanye ukugquma intambo yokutsala ubushushu, yenza uvavanyo oludityanisiweyo lokuguga (ubushushu obuphezulu + isitshizi setyuwa).

• Ukubonakaliswa kwe-UV: Ukusetyenziswa kolwandle lwangaphandle kufuna ukuxhathisa kwe-UV - i-adhesive kufuneka ingatshiki okanye idibanise phantsi kwemitha ye-ultraviolet.

5. Ufakelo kunye nokugcinwa

• Ukulungiswa komphezulu: Ukuthotywa ngokupheleleyo kunye nederust imiphezulu edityanisiweyo. Ukuthelekisa i-primer kuyacetyiswa ukuba kuphuculwe ukuhlangana kobuso kunye nokuthintela ukungena kwenkungu yetyuwa.

• Ukuhlolwa rhoqo: Qwalasela iincam zeteyiphu ngexesha lenkonzo ukuba ziyadumba okanye zixobuka. Buyisela iteyiphu engaphumelelanga ngokukhawuleza ukunqanda ukubola kwesakhiwo esidityanisiweyo.
