Inkqubo yemveliso ye-PTFE ikakhulu ibandakanya la manyathelo ama-4 alandelayo:
1. i-monomer synthesis
PTFEyi-polymerization ye-tetrafluoroethylene (TFE) i-polymerization ye-monomer ye-polymer compounds.i-monomer synthesis ye-TFE linyathelo lokuqala kwinkqubo yemveliso ye-PTFE.Okwangoku, ishishini ikakhulu isebenzisa indlela electrolytic fluorination ukulungiselela TFE monoma, okt, anhydrous hydrogen fluoride kunye ethylene phantsi kweemeko ezithile electrolysis reaction ukuvelisa TFE monoma.
2.Ipolymerization reaction
TFE monoma kwiqondo lobushushu ethile kunye noxinzelelo, yongeza i-catalyst kunye ne-solvent, i-polymerization reaction.Ngexesha le-polymerization reaction, i-TFE monomer iqhubeka i-polymerized ukwenza i-molecular weight PTFE, ubushushu, uxinzelelo, uhlobo lwe-catalyst kunye noxinaniso lwe-polymerization reaction kunye nezinye izinto ziya kuchaphazela ubunzima be-molecular, isakhiwo kunye neepropati ze-PTFE.
3.Unyango lwasemva
Emva kokuba i-polymerization reaction igqityiwe, unyango lwasemva luyafuneka ukuze ufumane iimveliso ze-PTFE ezisulungekileyo.Unyango lwasemva lubandakanya ukuhlamba, ukomisa, ukutyumza, ukuhluza kunye namanye amanyathelo okususa i-catalysts, i-solvents kunye nezinye izinto ezingcolileyo ukuze ufumane i-PTFE ye-resin ecocekileyo.
4.Inkqubo yokubumba
Amasuntswana eresin e-PTFE abunjwa phantsi kweemeko ezithile ukufumana okufunekayoPTFE iimveliso.Iindlela zokubumba ziquka i-extrusion, isitofu sokubumba, i-calendering njalo njalo, ngokweemfuno ezahlukeneyo zeemveliso ukukhetha indlela efanelekileyo yokubumba.Ubushushu benkqubo yokubumba, uxinzelelo, isantya sokulungisa kunye nezinye izinto ziya kuchaphazela ukusebenza kunye nomgangatho weemveliso ze-PTFE.
Imathiriyeli ekrwada ye-PTFE
I-Polytetrafluoroethylene (PTFE) resin yafunyanwa ngengozi zizazinzulu zaseMelika kwibhubhoratri ngo-1936, kwaye ngoku ihlabathi linokuvelisa i-PTFE kumazwe angaphantsi kwama-20, uninzi lwawo ngamazwe aphuhlileyo.I-China kwi-60s yokulawula iteknoloji yokuvelisa kunye nokuqonda imveliso, ibe ngumthengi omkhulu we-PTFE, apho iimveliso eziphantsi ziphezulu ngaphezu kwemfuno, kodwa iimveliso ezininzi eziphezulu zisadinga ukuthembela ekuthengisweni kumazwe aphuhlileyo. .
I-PTFE yangoku ye-PTFE imathiriyeli ekrwada kunye neemveliso zithengwa kumazwe angaphandle ikakhulu eMelika, eJapan, nakumazwe aseYurophu.Ngenxa yeendleko zothutho kunye nomjikelo wonikezelo, China ukungenisa eyona ixhaphakileyo yaseJapan, kunye neJapan yokungenisa iimveliso ze-PTFE ezisemgangathweni olungileyo ukuhlangabezana nemfuno yasekhaya yesiphelo esiphezulu.
Ngokwempendulo yomthengi wokugqibela, iimveliso kumandla omatshini wokusetyenziswa kwangempela kweemeko zokusebenza, ukuchasana nokukhwela kunye nokuzinza okuphezulu kunye nokushisa okuphantsi, izinto ezithunyelwa ngaphandle zingcono kunezixhobo zasekhaya.
Ukuthenga i-PTFE ityhubhu elungileyo ayikokukhetha kuphela iinkcukacha ezahlukeneyo kwizicelo ezahlukeneyo.Okunye ukukhetha umenzi othembekileyo.I-Besteflon Fluorine yeplastiki ye-Industry Co., Ltd. igxile ekuveliseni umgangatho ophezulu we-PTFE hoses kunye neetyhubhu ze-20 iminyaka.Ukuba kukho nayiphi na imibuzo kunye neemfuno, nceda uzive ukhululekile ukudibana nathi ukuze ufumane iingcebiso ezingakumbi.
