The manufacture of PTFE BESTEFLON

Inkqubo yokuvelisa i-PTFE ibandakanya ikakhulu la manyathelo ma-4 aphambili alandelayo:

1. ukwenziwa kwe-monomer

I-PTFEyi-polymerization ye-tetrafluoroethylene (TFE) monomer polymerization yeekhompawundi zepolymer. Ukwenziwa kwe-monomer ye-TFE linyathelo lokuqala kwinkqubo yemveliso ye-PTFE. Okwangoku, eli shishini lisebenzisa kakhulu indlela ye-electrolytic fluorination ukulungiselela i-TFE monomer, oko kukuthi, i-anhydrous hydrogen fluoride kunye ne-ethylene phantsi kweemeko ezithile ze-electrolysis reaction ukuvelisa i-TFE monomer.

2. Impendulo yePolymerization

I-TFE monomer kubushushu obuthile kunye noxinzelelo, yongeza i-catalyst kunye ne-solvent, i-polymerization reaction. Ngexesha le-polymerization reaction, i-TFE monomer iqhubeka i-polymerized ukwenza i-PTFE enobunzima obuphezulu beemolekyuli, ubushushu, uxinzelelo, uhlobo lwe-catalyst kunye noxinzelelo lwe-polymerization reaction kunye nezinye izinto ziya kuchaphazela ubunzima beemolekyuli, ulwakhiwo kunye neempawu ze-PTFE.

3. Emva konyango

Emva kokuba i-polymerization reaction igqityiwe, unyango olufunekayo emva kokufumana iimveliso ze-PTFE ezicocekileyo. Emva konyango lubandakanya ukuhlamba, ukomisa, ukutyumza, ukuhluza kunye namanye amanyathelo okususa ii-catalysts, izinyibilikisi kunye nokunye ukungcola ukuze kufunyanwe amasuntswana e-resin e-PTFE acocekileyo.

4. Inkqubo yokubumba

Iinxalenye ze-resin ze-PTFE zibunjwa phantsi kweemeko ezithile ukuze kufunyanwe okufunekayoPIimveliso zeTFEIindlela zokubumba ziquka ukukhupha, ukubumba ngenaliti, ukucola njalo njalo, ngokweemfuno ezahlukeneyo zeemveliso ukuze kukhethwe indlela efanelekileyo yokubumba. Ubushushu benkqubo yokubumba, uxinzelelo, isantya sokusebenza kunye nezinye izinto ziya kuchaphazela ukusebenza kunye nomgangatho weemveliso ze-PTFE.

Izinto eziluhlaza ze-PTFE

I-resin yePolytetrafluoroethylene (PTFE) yafunyanwa ngengozi zizazinzulu zaseMelika kwilebhu ngo-1936, kwaye ngoku ihlabathi linokuvelisa i-PTFE kumazwe angaphantsi kwama-20, uninzi lwawo amazwe aphuhlileyo. I-China kwiminyaka yoo-60 ukuze ikwazi ubugcisa bemveliso kwaye ifezekise imveliso, iye yaba ngumthengi omkhulu we-PTFE, apho iimveliso ezikumgangatho ophantsi ziye zaba ngaphezu kwemfuno, kodwa iimveliso ezininzi ezikumgangatho ophezulu zisafuna ukuxhomekeka ekungenisweni okuvela kumazwe aphuhlileyo.

Izinto kunye neemveliso zePTFE zaseTshayina ngoku zithunyelwa kakhulu zivela eMelika, eJapan, nakwamanye amazwe aseYurophu. Ngenxa yeendleko zokuhamba kunye nomjikelo wokubonelela, iTshayina ingenisa ezona zixhaphakileyo eJapan, kunye nokungeniswa kwemveliso zePTFE ezisemgangathweni olungileyo eJapan ukuhlangabezana neemfuno zasekhaya zexabiso eliphezulu.

Ngokwengxelo yabathengi bokugqibela, iimveliso ezisebenza ngamandla oomatshini, ukumelana nokurhubuluza kunye nozinzo lobushushu obuphezulu nobuphantsi, izinto ezingeniswa kwamanye amazwe zingcono kunezixhobo zasekhaya.

Ukuthenga iityhubhu zePTFE ezifanelekileyo akupheleli nje ekukhetheni iinkcukacha ezahlukeneyo zezicelo ezahlukeneyo. Okungakumbi ukukhetha umenzi othembekileyo. I-Besteflon Fluorine plastic Industry Co., Ltd. igxile ekuveliseni iipayipi zePTFE ezikumgangatho ophezulu kunye neetyhubhu kangangeminyaka engama-20. Ukuba unemibuzo kunye neemfuno, nceda uzive ukhululekile ukuqhagamshelana nathi ukuze ufumane iingcebiso zobungcali ezingakumbi.
