Iteyiphu ye-PTFE yesitywini sobushushu ayinamanzi, kwaye sesinye sezizathu eziphambili ekuthenjwe ngayo kuwo onke amashishini aphatha ukupakishwa kobushushu obuphezulu kunye nezixhobo zokutywina. I-PTFE, imfutshane ye-polytetrafluoroethylene, yimathiriyeli eyaziwa ngomgangatho wayo ogqwesileyo wokunganamatheli, ukunganyangeki kweekhemikhali, kunye nokhuselo olupheleleyo lokungena kokufuma. Xa isetyenziswe njengeteyiphu, ngokukodwa kwimisebenzi yokutywinwa kobushushu, yenza umqobo ochasayo amanzi, umphunga, kunye nolunye ulwelo-naphantsi kwamaqondo obushushu.
Ngaphezu koko, i-adhesive ye-silicone esetyenziswa ngasemva kweeteyiphu ezininzi ze-PTFE iqinisekisa ukubambana okuzinzile ngaphandle kokuphuma kwamanzi, nasemva kokusetyenziswa ixesha elide. Ngamafutshane, ukuba ujonge iteyiphu exhathisa amanzi ngelixa umile ukuya kumaqondo obushushu aphezulu kunye nokusetyenziswa okuphindaphindiweyo, iteyiphu ye-PTFE yesitywini sobushushu sisisombululo esithembekileyo.

Iteyiphu ye-PTFE yeSitywini soBubushushu: iiPropati zokuNgangeni manzi kunye nokuChasa uBubushushu
Iteyiphu ye-PTFE yesitywini sobushushu yenziwe ngentsebenzo kabini engqondweni: ukumelana nobushushu obuphezulu kunye nomqobo opheleleyo wokufuma. Ezi mpawu zimbini zibalulekile xa ujongene neenkqubo zokuvala ubushushu, ngakumbi ekupakishweni kwempahla efumileyo okanye etshabalalayo.
IiPropati ezingeManzi kwiiNdawo eziBangayo
Ukungangeni kwamanzi akukhona nje ukugxotha amanzi-kumalunga nokugcina ukusebenza ngokuhambelanayo kungakhathaliseki ukuba iimeko ezingqongileyo. Ulwakhiwo lwemolekyuli ye-PTFE yenza umphezulu we-hydrophobic othintela iimolekyuli zamanzi ukuba zingagqobhozi okanye zitshintshe indlela ebonakalayo yetheyiphu. Oku kuvumela ukuba kugcinwe ukunamathela kunye nokugquma, nangona kubonakaliswe kwi-steam okanye i-condensation kwizixhobo zokutywinwa.
Iteyiphu ye-PTFE isoloko isetyenziswa kwimihlathi yokufudumeza yezitywini zobushushu apho iplastiki etyhidiweyo yenza ibhondi. Ukufuma kulo mmandla kunokuwenza buthathaka amatywina okanye kuchaphazele ukufana. I-tape isebenza njengesithintelo esikhuselayo, esingabambekiyo esiqinisekisa ukuba inkqubo yokutywinwa ihlala ingachaphazeleki kukufuma kokusingqongileyo okanye iintsalela zamanzi.
Ukumelana nobushushu kunye nokuzinza kokuSebenza
Ecaleni kweempawu zayo zokugxotha ukufuma, iteyiphu ye-PTFE inokumelana nokusetyenziswa rhoqo kumaqondo obushushu ukusuka ku -54°C ukuya ku-260°C. Olu luhlu lubanzi luxabiseke ngokukodwa kwimigca yokutywina enesantya esiphezulu apho oomatshini basebenza kumaqondo obushushu aphakamileyo kangangeeyure ngexesha. Ngokungafaniyo neeteyiphu eziqhelekileyo ezinokunyibilika, zolule, okanye zithobe, i-PTFE igcina ulwakhiwo kunye nokusebenza kwayo.
I-adhesive adhesive backing esetyenziswa kwiiteyiphu ezininzi ze-PTFE ikwanegalelo ekomeleleni kwayo. Ibambelela ngokuqinileyo kwimigangatho yentsimbi efudumeleyo, ixhathisa ukukhupha, kwaye ayishiyi intsalela emva kokususwa. Oku kubangela ukutywinwa okucocekileyo, okusebenzayo kunye nexesha elincinane lokucoca okanye ukutshintshwa.
Ngokwenene, indibaniselwano yokumelana nokungangeni kwamanzi kunye nokunyamezela kwe-thermal kwenza i-PTFE tape ibe yeyona nto iphambili kwizicelo zokutywinwa kobushushu ezifuna ukuthembeka phantsi koxinzelelo.
Ngaba Unokusebenzisa iTape ye-PTFE ukuNqanda ukuvuza kwizicelo zoBubushushu obuphezulu?
Iteyiphu ye-PTFE isetyenziswa rhoqo hayi nje ngomqobo omelana nobushushu kodwa nanjengesixhobo sokuthintela ukuvuza. Ukukwazi ukusebenza njengendawo yokutywina phantsi kweemeko ezinzulu zokushisa kunye noxinzelelo zivumela ukuba isetyenziswe ngaphezu kokupakisha-ikwasetyenziswa kwiinkqubo apho ukuvuza kwamanzi kufuneka kuphetshwe.
UThintelo lokuvuza kwiiSystems ezinoxinzelelo
Ukunganyameki kwe-PTFE kulwelo kunye neegesi kuyenza ilungele ukusonga amalungu anentambo, uqhagamshelo lwemibhobho, kunye nokufakwa kwiinkqubo zoshishino. Kwiindawo ezinobushushu obuphezulu obufana nemigca yomphunga okanye iinkqubo zokuhanjiswa kweekhemikhali ezifudunyeziweyo, i-PTFE tape isebenza njengesithinteli esivala izikhewu ezincinci kunye nokuthintela ukuphuma kwezinto.
Ngelixa iteyiphu ye-PTFE yesitywini sobushushu iyilelwe ikakhulu non-stick kunye nokugquma izicelo kwizixhobo zokufudumeza, imathiriyeli yesiseko sayo yabelana ngeempawu zokutywina ezifanayo ezifumaneka kwiteyiphu zokutywina ze-PTFE. Nangona kunjalo, kubalulekile ukwahlula phakathi kweteyiphu encamathelayo esetyenziswa ekutywineni imihlathi kunye nokwahluka kokutywinwa komsonto ongabambeleliyo. Zombini zibopha ukuxhathisa kwe-thermal kunye neekhemikhali ze-PTFE, kodwa iimeko zokusetyenziswa kwazo ziyahluka.
Ukuqina phantsi koxinzelelo lwe-Thermal
Olunye lweempawu ezinomtsalane zeteyiphu kukuba igcina iimpawu zayo zokuthintela ukuvuza nasemva kokuvezwa kwibhayisekile ephinda-phindayo yobushushu. Kwiinkqubo ezipholileyo kunye nobushushu obujikelezayo, izinto ezininzi ziyakhula kwaye zikhontrakthi, zenza ukuba sesichengeni sokuvuza. Itheyiphu ye-PTFE ithatha le ntshukumo ngaphandle kokuqhekeka okanye ukulahleka kokuncamathela, iyenza ibe sisisombululo esithembekileyo sokutywinwa.
Xa isetyenziswa kunye neeyunithi zokutywinwa kobushushu, iteyiphu ye-PTFE ayiphuculi kuphela umphezulu wokutywina kodwa ikwaxhathisa ukungena kwamanzi okunokuthi ngenye indlela kuchaphazele isixhobo. Lo msebenzi ombini-zombini njengonyango oluphezulu kunye noluhlu lokuthintela ukuvuza-yongeza ixabiso kwindima yalo kwiindawo zokuvelisa ubushushu obuphezulu.
Izisombululo zokutywina eziManzi: Indlela i-PTFE Tape eSebenza ngayo kunye neziBonelelo zoBubushushu
Izitywini zobushushu zibalulekile kwimisebenzi yokupakisha, ngakumbi kumashishini apho ulawulo lokufuma lubalulekile. Nokuba kutywinwa ukutya, amayeza, okanye imathiriyeli yaselabhoratri, ubukho bamanzi okanye umphunga bunokubeka esichengeni ukuthembeka kwemveliso. Kulapho itheyiphu yePTFE iba yimfuneko.
Ukudala i-Non-Stick, isithintelo esingenaManzi
Ukutywinwa kobushushu kufuna into enokunxibelelana ngokuthe ngqo nezinto ezishushu ngaphandle kokuthotywa okanye ukubambelela kwiifilimu zeplastiki. Iteyiphu ye-PTFE ibonelela ngomphezulu otyibilikayo, ongabambekiyo othintela iplastiki enyibilikayo ukuba ingabambeleli kubushushu bemihlathi. Oku kukodwa kuphucula ukusebenza kakuhle kunye nokunciphisa imfuno yokucoca rhoqo.
Ukongezelela, i-tape yenza uluhlu olungenamanzi olukhusela into yokufudumala kwi-contaminants yamanzi. Ingaba izinto zokupakisha ziqulethe ukufuma okanye umgca wemveliso usebenza kwindawo efumileyo, i-PTFE tape ye-heater sealer igcina ukusebenza kwetywina okuhambelanayo. Ikhusela umphunga okanye amanzi ekufikeleleni kumalungu angaphakathi abuthathaka, ukwandisa ubomi besixhobo sokushisa ubushushu.
Ukuphucula uMgangatho weTywina kwiiMeko ezifumileyo
Kwiisethingi ezityebileyo zokufuma, iteyiphu ye-PTFE ikwanceda ukuvelisa amatywina anamandla, afanayo. Ngaphandle kwayo, umphunga wamanzi unokuphazamisana nebhondi yeplastiki okanye ubangele ukuncamathela okungalinganiyo. Umphezulu weteyiphu ogudileyo kunye nokuhambelana kwe-thermal kuqinisekisa ukucoceka, ukutywinwa okuphindaphindiweyo, kungakhathaliseki ukuba bunjani ukufuma.
Igalelo leteyiphu ye-PTFE lidlulela ngaphaya kokukhusela nje isixhobo-ikwaphucula imveliso yokugqibela. Iipakethi ezitywinwe ngezixhobo ezikhuselweyo ze-PTFE azifane zibonise iindawo ezibuthathaka, imibimbi, okanye itywina eliyinxalenye, ebaluleke kakhulu kwiimveliso ezivaliweyo okanye ezinokonakala.
Ngokusebenza njengesithintelo kunye nesixhasi sokusebenza, i-PTFE tape izibonakalisa njengesisombululo esithembekileyo sokutywinwa kwamanzi kwiindawo eziphezulu zemveliso.
Isishwankathelo
Ke, ngaba i-PTFE tape ayinamanzi? Ngokuqinisekileyo-kwaye ayisiyiyo loo nto kuphela, yakhelwe ukuba iphumelele kwiindawo apho zombini amanzi kunye nobushushu obuphezulu buyinto eqhelekileyo. Ngokukodwa xa isetyenziselwa i-PTFE tape yokushisa ubushushu , inikezela ngokuqhubekayo, ukusebenza okuzinzileyo ngokugcina ukufuma ngaphandle, ukuxhathisa ukusebenzisana kweekhemikhali, kunye nokugcina uzinzo lwe-thermal. Nokuba usebenzisa umgca wokupakisha ohamba ngesantya esiphezulu okanye usebenza kwindawo yokufuma-bunzima bemizi-mveliso, iteyiphu ye-PTFE iqinisekisa ukuba izixhobo zakho kunye netywina lakho zihlala zicocekile, zikhuselekile kwaye zisebenza.
