Terephthalal acid cas 100-21-0 / PTA
Terephthaal Acid inonyanya kushandiswa kubereka polyethlene terephthalate terephthalate Pet inozivikanwa nekuda kwesimba rayo, kugadzikana kwekunyora, uye kupusa kuramba. Uye zvakare, terephthalal acid inoshandiswa kuburitsa akasiyana zvimwe zvezvimwe zvinhu, kusanganisira:
1. Zvinyoro: Iyo yakakosha chinongedzo mukugadzirwa kwePolyester fiber, iyo inoshandiswa mune zvipfeko uye zvinhu zveimba.
2. Resin: Terephthaal Acid inoshandiswa kugadzirira dzakasiyana-siyana marara.

Yakarongedzwa mu25 kg pa chigubhu kana kubva pane zvevatengi zvinodiwa nevatengi.
Kuchengetedza zvakachengeteka terephthaal acid, tevera izvi nhungamiro:
1. Mudziyo: Chitoro terephthaal acid mumidziyo yakasungwa yakagadzirwa nezvinhu zvakakodzera, zvakadai segirazi kana yakakwirira-density polyethylene (HDPE) kudzivirira kusvibiswa uye kunyorova kusvibiswa.
2. Nzvimbo: Chengetedza mudziyo mune inotonhorera, yakaoma uye yakanyorova nzvimbo kure kubva kune yakananga zuva uye kupisa masisitiri. Dzivisa kuchengetedza munzvimbo dzine hupfumi hwakanyanya.
3. Tembiricha: Chengetedza tembiricha yekuchengetedza mukati meiyo yakakurudzirwa mhando, kazhinji pazasi 25 ° C (77 ° F), kudzivirira kusvibiswa kana kuchinja mune zvivakwa.

Paunenge uchitakura terephthaal acid, zvakakosha kutevedzera zvakananga zvekudzivirira kuti uve nechokwadi chekuchengetedza uye kutevedzera nemirairo. Heano mamwe mafungiro akakosha kuti afunge nezve:
1. Kutakura: Shandisa midziyo yakakodzera iyo inoenderana neTerephthalic acid. Kazhinji, zvinofanirwa kuchengetwa mumidziyo yakasungwa, yakanyorwa nemidziyo yakagadzirwa nezvinhu zvisingaite neakari.
2. Simbisa kuti kusavimbika kunoenderana nemitemo yemuno uye yenyika.
3. Zvitendero zvekutakura: Tevedza mirau yekufambisa kwemakemikari, senge Dhipatimendi reUS rekufambisa (dot) kana iyo International Air Advan Association (IATA) yekufambisa yemhepo. Terephthaal acid haiwanzo zivikanwa seyakagwinya, asi zvakakosha kuti uone zvirevo zvakananga.
