Kagwiritsidwe Ntchito
Dioctyl terephthalate (DOTP) ndi pulasitiki yaikulu yomwe imagwira ntchito bwino kwambiri pa pulasitiki ya polyvinyl chloride (PVC). Poyerekeza ndi diisooctyl phthalate (DOP) yomwe imagwiritsidwa ntchito kwambiri, ili ndi ubwino wokana kutentha, kukana kuzizira, kukana kuzizira, kukana kutulutsa zinthu, kufewa, komanso mphamvu zabwino zamagetsi. Imasonyeza kulimba bwino, kukana madzi a sopo komanso kufewa pang'ono pa kutentha m'zinthu. Chifukwa cha kusinthasintha kwake kochepa, kugwiritsa ntchito DOTP kumatha kukwaniritsa zofunikira za mawaya ndi zingwe zokana kutentha, ndipo ingagwiritsidwe ntchito kwambiri pazinthu zokana kutentha mpaka madigiri 70.° C (muyezo wa IEC wa International Electrotechnical Commission) ndi zinthu zina zofewa za PVC.
Kuwonjezera pa mapulasitiki ambiri opangira zinthu za chingwe ndi PVC, DOTP ingagwiritsidwenso ntchito popanga mafilimu a chikopa chopangidwa. Kuphatikiza apo, DOTP ili ndi kusungunuka kwabwino kwambiri ndipo ingagwiritsidwenso ntchito ngati mapulasitiki opangira zinthu zopangidwa ndi acrylonitrile, polyethylene, alcohol butyraldehyde, nitrile rabara, nitrocellulose, ndi zina zotero. Ingagwiritsidwenso ntchito ngati mapulasitiki opangira mphira, zowonjezera zokutira, mafuta odzola zida zolondola, zowonjezera zowonjezera, ndi zofewetsa mapepala.
Kulongedza ndi Kutumiza
Kulongedza: 250 kg/ng'oma kapena malinga ndi zosowa za makasitomala.
Kutumiza: ndi mankhwala wamba ndipo amatha kutumizidwa ndi sitima, nyanja ndi mpweya.
Stock: ali ndi stock yotetezeka ya 500MTs
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
