DIISONONYL PHTHALATE (DINP) ndi mankhwala achilengedwe okhala ndi C26H42O4. Ndi madzi owoneka bwino amafuta okhala ndi fungo laling'ono. Mankhwalawa ndi pulasitiki woyambira wachilengedwe wokhala ndi magwiridwe antchito abwino kwambiri. Mankhwalawa ndi PVC zimasungunuka bwino, ndipo sizingawonongeke ngakhale zitagwiritsidwa ntchito kwambiri; kusasinthasintha, kusamuka, komanso kusawononga ndikwabwino kuposa DOP, zomwe zingapangitse kuti mankhwalawa akhale olimba mtima, okana kutentha, okana ukalamba komanso okana magetsi. Magwiridwe antchito onse ndi abwino kuposa DOP imeneyo. Chifukwa zinthu zomwe zimapangidwa ndi mankhwalawa zimagwiritsidwa ntchito bwino, zimakhala zolimbana ndi madzi, zofooka zochepa, zofooka, komanso zoteteza magetsi bwino, zimagwiritsidwa ntchito kwambiri mu filimu yoseweretsa, mawaya, ndi zingwe.
Kapangidwe ka mankhwala:Madzi amafuta opanda mtundu kapena achikasu chopepuka. Osasungunuka m'madzi, amasungunuka mu aliphatic ndi aromatic hydrocarbons. Kusinthasintha kwake kumakhala kochepa kuposa DOP. Ali ndi mphamvu yabwino yolimbana ndi kutentha.
DINP ili ndi magwiridwe antchito abwino kuposa DOP:
1. Poyerekeza ndi DOP, kulemera kwa mamolekyulu ndi kwakukulu komanso kwakutali, kotero kumakhala ndi magwiridwe antchito abwino okalamba, kukana kusamuka, magwiridwe antchito oletsa kupha, komanso kukana kutentha kwambiri. Mofananamo, pansi pa mikhalidwe yomweyi, zotsatira za pulasitiki za DINP zimakhala zoyipa pang'ono kuposa DOP. Kawirikawiri amakhulupirira kuti DINP ndi yoteteza chilengedwe kuposa DOP.
2. DINP ili ndi ubwino wowonjezera ubwino wa extrusion. Pansi pa mikhalidwe yachizolowezi yogwiritsira ntchito extrusion, DINP imatha kuchepetsa kukhuthala kwa kusungunuka kwa chisakanizo kuposa DOP, zomwe zimathandiza kuchepetsa kupanikizika kwa chitsanzo cha port, kuchepetsa kuwonongeka kwa makina kapena kuwonjezera zokolola (mpaka 21%). Palibe chifukwa chosinthira njira yopangira zinthu ndi njira yopangira, palibe ndalama zowonjezera, palibe kugwiritsa ntchito mphamvu zowonjezera, komanso kusunga mtundu wa zinthu.
3. DINP nthawi zambiri imakhala yamafuta, yosasungunuka m'madzi. Nthawi zambiri imanyamulidwa ndi matanki, zidebe zazing'ono zachitsulo kapena migolo yapadera yapulasitiki.
Mapulogalamu:
- Mankhwala omwe amagwiritsidwa ntchito kwambiri omwe amatha kusokoneza chithokomiro. Amagwiritsidwa ntchito mu maphunziro a poizoni komanso maphunziro owunikira zoopsa za kuipitsidwa kwa chakudya komwe kumachitika chifukwa cha kusamuka kwa ma phthalates kupita ku chakudya kuchokera kuzinthu zolumikizirana ndi chakudya (FCM).
- Mapulasitiki ogwiritsidwa ntchito nthawi zonse omwe amagwiritsidwa ntchito pa PVC ndi ma vinyl osinthasintha. 3. Diisononyl Phthalate ndi pulasitiki wamkulu, yemwe amagwiritsidwa ntchito muzinthu zosiyanasiyana zapulasitiki zolimba ndi zolimba, zomwe zimatha kusakanikirana ndi mapulasitiki ena popanda kukhudza mawonekedwe ake.
Mikhalidwe yosungira ndi mayendedwe:Sungani chipangizo chosungiramo zinthu chotsekedwa, chosungidwa pamalo ozizira komanso ouma, ndipo onetsetsani kuti malo ogwirira ntchito ali ndi chipangizo chopumira mpweya wabwino kapena chotulutsira utsi.
