I-Terephthalic Acid Acid i-100-21-0 / PTA
I-Terephthayic Acid isetyenziselwa ukuvelisa i-Polythyene Terehthane Terephthalate (PET), ipolymer isetyenziselwa ukwenza iibhotile zeplastiki, izikhongozeli, kunye neentsinga zokwenziwa. Isilwanyana sasekhaya saziwa ngamandla abo, uzinzo se-shirmal, kunye nokunganyangeki komswakama. Ukongeza, i-Terephthayic Acid isetyenziselwa ukuvelisa iintlobo ezahlukeneyo, kubandakanya:
I-1. Izibalo: Sisithako esiphambili ekuvelisweni kwefayibha ye-polyester, esetyenziselwa iimpahla zempahla kunye nekhaya.
2. I-Reden: I-Terephthayic Acid isetyenziselwa ukulungiselela i-resins ezahlukeneyo kunye neengubo.
3. Iplastiki: ibandakanya ukuveliswa kweplasitiki yobunjineli efuna ukuqina okuphezulu kunye nokuxhathisa imichiza.
I-4. Izongezo: I-Terephthayic Acid inokusetyenziswa njengemichiza ephakathi kwi-synthes yeminye imichiza.
Ipakishwe nge-25 kg nganye yedrum okanye isekwe kwiimfuno zabathengi.
Ukugcina ngokukhuselekileyo i-terephthacc acid, landela ezi zikhokelo:
I-1. Isikhongozeli: Gcina i-terephthayic i-acid etywiniweyo eyenziwe ngezinto ezifanelekileyo, ezinjengeglasi okanye i-polythylene (i-phullylene) yokuthintela ungcoliseko kunye nokuthambisa.
I-2. Indawo: Gcina isikhongozeli kwindawo epholileyo, eyomileyo nenehlakele kwaye ingena kakuhle ukusuka kwilanga kunye nemithombo yobushushu. Kulumkele ukugcinwa kwiindawo ezine-suidity ephezulu.
3. Ubushushu: Gcina iqondo lobushushu kuluhlu olucetyiswayo, oluqhelekileyo ngaphantsi kwe-25 ° C (77 ° F), ukuthintela ukonakaliswa okanye utshintsho kwiipropathi.
4. Ileyibhile: Ileyibhile yelebheli ngegama elinegama leekhemikhali, ulwazi olunobungozi, kunye nerisha, kunye nomhla wokufumana irisithi ukuze kuqinisekiswe isazisi esifanelekileyo kunye nokuphatha.
5. Ukwahlula: Nceda ugcine kude nezinto ezingahambelani, njengee-onudants ezinamandla, ukuthintela nayiphi na indlela enokubakho.
6. Amanyathelo okhuseleko: Qinisekisa ukuba amanyathelo okhuseleko okhuseleko akwindawo, kubandakanya izixhobo zokhuselo (PPE) kuye nabani na owuphathe umxholo.
I-Terephthayic Acid ithathelwa ingqalelo ukuba inobuqili obuphantsi, kodwa ikwabeka umngcipheko othile kwiimeko ezithile. Nazi ezinye iindawo eziphambili malunga nokwenzakala kwayo ebantwini:
I-1. Ukuphefumla kunye nolusu uNxibelelwano: Ukuvezwa kwexesha elide kwi-Terephthayic Uthuli okanye umphunga unokucaphukisa iphecana lokuphefumla, ulusu kunye namehlo. Kucetyiswa ukuba usebenzise izixhobo ezifanelekileyo zokukhusela xa uphathe ezi zixhobo.
2. I-Investion: Nangona i-terephthayic i-Acid ayihlali ingeniswe, ukuthathwa kwengozi kunokubangela ukucaphukisa i-gestrointenal.
3. Imeko yolawulo: I-Terephthayic Acid ayihlelwanga njenge-carcinogen okanye ingozi yempilo ebalulekileyo yeMpilo nemibutho ephambili yempilo, kodwa iPhepha leDatha loKhuseleko.
I-4. Impembelelo yokusiNgqongileyo: Nangona i-terephthayic acid ayibangeli ingozi ngqo emzimbeni womntu, ukuba ikhutshiwe ngesixa esikhulu, iya kuba nefuthe kwindalo esingqongileyo, ngaloo ndlela ichaphazela impilo yempilo.
Xa uhambisa i-Terephthalic Acid, kubalulekile ukulandela amanyathelo athile okuqinisekisa ukhuseleko kunye nokuthotyelwa kwemigaqo. Nazi ezinye zeengqwalaselo eziphambili zokuthatha ingqalelo:
1. Ukupakisha: Sebenzisa izikhongozeli ezifanelekileyo ezihambelana ne-Terephthayic i-Acid. Ngokubanzi, kufuneka igcinwe kwizitya ezitywiniweyo, ezifakwe iilebheli ezenziwe ngezinto ezingasasebenziyo nge-acid.
I-2. Ileyibhile: Ilebheli ifake ilebheli yonke indawo enamagama emichiza achanekileyo, iisimboli ezinobungozi kunye nokuphatha imiyalelo. Ukuqinisekiswa ileyibhile kuyahambelana neMigaqo yeNdawo yeNdawo.
3. Imigaqo yoThutho: Landela imigaqo yokuhamba kwamachiza, njengePhondo lezoThutho (i-DOT) okanye uMbutho wezoThutho yoMoya wase-Africa (Ita) yothutho lomoya. I-Terephthayic Acid ayihlelwanga ngokubanzi njengeyingozi, kodwa kubalulekile ukuqinisekisa imigaqo ethile.
4. Ulawulo lobushushu: IVenkile kunye neThutha i-Terephthayic i-Acid epholileyo neyomileyo ukuthintela ukonakaliswa okanye ukuphendula ngomswakama.
5. Khusela ungcoliseko: Qinisekisa ukuba akukho ngcoliseko kwindawo yothutho enokuthi iphendule nge-terephthayic i-acid yeTerephthayic.
I-6. Izixhobo zokhuselo lobuqu (i-PPE): Ukuqinisekisa ukuba abasebenzi baphatha inkqubo yothutho inxiba i-PPE efanelekileyo, njengeigloves kunye neegloves, ukuthintela umthambo kunye nokunxibelelana ngamehlo.
7. Inkqubo yexesha likaxakeka: Kwimeko yokuchitheka okanye ukuvuza ngexesha lezothutho, phuhlisa iinkqubo zikaxakeka. Oku kubandakanya ukuba nekhithi yokuchitha kunye noncedo lokuqala olulungile.
8. Amaxwebhu: Gcina amaxwebhu afanelekileyo okuthunyelwa, kubandakanya amaphepha edatha ezokhuseleko (i-SDS) kunye nayiphi na imvume efunekayo okanye izibhengezo.
