Hoʻohana
ʻO Dioctyl terephthalate (DOTP) kahi plasticizer nui me ka hana maikaʻi loa no nā plastics polyvinyl chloride (PVC). Ke hoʻohālikelike ʻia me ka diisooctyl phthalate (DOP) i hoʻohana pinepine ʻia, loaʻa iā ia nā pono o ke kūpaʻa wela, ke kūpaʻa anu, ka volatilization paʻakikī, ka anti-extraction, ka palupalu, a me nā waiwai insulation uila maikaʻi. Hōʻike ia i ka lōʻihi maikaʻi loa, ke kūpaʻa wai kopa a me ka palupalu haʻahaʻa haʻahaʻa i nā huahana. Ma muli o kona volatility haʻahaʻa, hiki i ka hoʻohana ʻana o DOTP ke hoʻokō piha i nā koi pae kūpaʻa mahana o nā uea a me nā kaula, a hiki ke hoʻohana nui ʻia i nā mea uea e kū i ka 70° C (ke kūlana IEC o ka International Electrotechnical Commission) a me nā huahana palupalu PVC ʻē aʻe.
Ma waho aʻe o ka nui o nā plasticizers no nā mea kaula a me PVC, hiki ke hoʻohana ʻia ʻo DOTP i ka hana ʻana i nā kiʻiʻoniʻoni ʻili artificial. Eia kekahi, loaʻa iā DOTP ka solubility phase maikaʻi loa a hiki ke hoʻohana ʻia e like me nā plasticizers no nā acrylonitrile derivatives, polyethylene, alcohol butyraldehyde, nitrile rubber, nitrocellulose, etc. Hiki ke hoʻohana ʻia e like me nā plasticizers no ka synthetic rubber, nā mea hoʻohui uhi, nā lubricants mea hana pololei, nā mea hoʻohui lubricant, a me nā mea palupalu no ka pepa.
ʻŌpala a me ka Hoʻouna ʻana
Hoʻopili ʻia: 250 kg / pahu a i ʻole e like me nā koi a ka mea kūʻai aku.
Hoʻouna: no nā kemika maʻamau a hiki ke hāʻawi ma ke kaʻaahi, ke kai a me ka lewa.
Waihona: loaʻa iā 500MTs waihona palekana
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
