Ushishino lwePolyester Luseyeyona ndawo iphambili ekusetyenzisweni kuyo

Enye yezona ndawo zisetyenziswa kakhulu kwi-ethylene glycol kukuveliswa kwe-polyester, ingakumbi ekuvelisweni kwe-polyethylene terephthalate (PET). I-ethylene glycol isebenza njengezinto ezibalulekileyo kwinkqubo ye-polymerization.

Izixhobo ze-PET zisetyenziswa kakhulu kwezi:

Ukuveliswa kwefayibha yepolyester;
Iibhotile zesiselo kunye nezixhobo zokupakisha ukutya;
Iifilimu kunye neemveliso zeplastiki zoshishino.

Kwimveliso ye-polyester, ubunyulu kunye nokungaguquguquki kwe-ethylene glycol kunokuchaphazela uzinzo lwe-polymerization kunye nomgangatho wemveliso. Ke ngoko, abathengi bemizi-mveliso badla ngokunika ingqalelo esondeleyo kulawulo lomgangatho kunye nokuthembeka kobonelelo lwexesha elide.

Iingenelo zokusebenza kwi-Antifreeze kunye ne-Cooling Applications

Ngaphandle kokuveliswa kwepolyester, i-ethylene glycol ikwayinxalenye ebalulekileyo kwiinkqubo ze-antifreeze zeemoto kunye neenkqubo zokupholisa izimboni.

Ngenxa yokuba iphantsi kakhulu kwindawo yokukhenkceza kunye neempawu ezintle zokudlulisa ubushushu, i-ethylene glycol inceda ukugcina ukusebenza okuzinzileyo kweenjini kunye nezixhobo zoshishino phantsi kweemeko zobushushu obuphantsi.

Kwezi zicelo, abasebenzisi badla ngokugxila kwezi:

Ubumsulwa bemveliso;
Ubungakanani bokufuma;
Uzinzo kwindawo yokugcina izinto;
Ukuhambelana nezinye izinto ezisetyenzisiweyo.

Ukusebenza okuzinzileyo kwezinto eziluhlaza kunceda ukuphucula ukuhambelana nokuthembeka kweemveliso zokugqibela.

Ukuthembeka kobonelelo kuba yinto ebalulekileyo ekuthengeni

Kubavelisi abaneemfuno zemveliso eziqhubekayo, uzinzo lokubonelela lubaluleke njengomgangatho wemveliso. Ngexesha lokuthengwa kwamanye amazwe, abathengi badla ngokuvavanya oku kulandelayo:

Iinkqubo zolawulo lomgangatho;
Gcwalisa amaxwebhu obuchwephesha afana ne-COA kunye ne-SDS;
Izisombululo zokupakisha nezokuthutha;
Iishedyuli zokuhanjiswa ezithembekileyo.

Inkqubo yokubonelela ngobuchwephesha inceda abathengi ukunciphisa iingozi zekhonkco lokubonelela ngo ...

Ukugcina Imveliso Ngendlela Efanelekileyo Kunceda Ukugcina Umgangatho Wayo

I-ethylene glycol kufuneka igcinwe phantsi kweemeko ezifanelekileyo ukuze iqhubeke isebenza. Abasebenzisi bemizi-mveliso badla ngokucebisa ukuba igcinwe ivaliwe kwiindawo ezomileyo nezinomoya ococekileyo ukuze kuncitshiswe ukuvezwa komswakama kunye nokugcina uzinzo lwemveliso.

Ulawulo olufanelekileyo lokugcina izinto lunceda ekunciphiseni iingozi ezisemgangathweni ngexesha lokuthuthwa kunye nexesha elide lokugcina izinto.

Ixabiso le-Ethylene Glycol lexesha elide kwiShishini

Ngenxa yenkqubo yayo yokusetyenziswa evuthiweyo kunye neempawu zokusebenza ezizinzileyo, i-ethylene glycol iyaqhubeka nokusebenza njengezinto ezibalulekileyo kwimizi-mveliso eyahlukeneyo, kubandakanya ukwenziwa kweekhemikhali, iimoto, ukupakisha kunye neempahla.

Kubathengi bemizi-mveliso, ukukhetha umthengisi onokukwazi ukubonelela ngemveliso ngendlela ezinzileyo, ulawulo oluqinileyo lomgangatho, kunye namava obuchwephesha okuthumela ngaphandle yinto ebalulekileyo ekuqinisekiseni imveliso eqhubekayo nesebenzayo.
