Whakaahuatanga
Ko te Dibutyl phthalate, e mohiotia ana ko te dibutyl phthalate, te dibutyl phthalate ranei, te reo Ingarihi: Dibutylphthalate, he wai hinuhinu marama kore tae me te taumaha motuhake o 1.045 (21°C) me te ira koropuputanga o 340°C, kare e rewa i roto i te wai, wairewa-wai-wai me te wariu He tino iti te wairewa, engari he ngawari te wairewa i roto i te enol, engari he ngawari te wairewa i roto i te enol i roto i te enol, he ngawari noa iho. te etera, te acetone me te benzene, ka uru ano hoki ki te nuinga o te waiwaro. Ko te Dibutyl phthalate (DBP), te dioctyl phthalate (DOP) me te diisobutyl phthalate (DIBP) ko nga mea whakahiato e toru e tino kitea ana, he kirihou, he rapa waihanga me te hiako horihori, me etahi atu mea e whakamahia nuitia ana. Ka whiwhihia ma te whakamaarama waiariki o te phthalic anhydride me te n-butanol.
Nga Ahuatanga matū
He wai hinuhinu marama kore tae me te kakara kakara. Wairewa i roto i te whakarewa pararopi noa me te waiwaro.
Taupānga
-I whakamahia hei peera mo te nitrocellulose, cellulose acetate, polyvinyl chloride, me etahi atu. Ko tenei hua he kirihou. He kaha tareka te mana ki nga momo kapia.
-I whakamahia mo te tukatuka PVC, ka taea e ia te tuku ngawari ki nga hua. Na te iti me te pai o te mahi, he tino nui te whakamahi, tata ki te DOP. Heoi, he ahua nui te ahua o te wai me te tangohanga wai, no reira he kino te mauroa o te hua, a me whakatiki haere te whakamahi. Ko tenei hua he kaitarai pai o te nitrocellulose me te kaha o te reera.
-I whakamahia mo nga paninga nitrocellulose, he tino pai te whakangawari. He pai te pumau, te parenga ngawari, te piri me te aukati wai. I tua atu, ka taea te whakamahi i te hua hei plasticizer mo te polyvinyl acetate, te alkyd resin, te ethyl cellulose me te neoprene, ka taea hoki te whakamahi i roto i te hanga peita, whakapiri, hiako horihori, waituhi tuhi, karaihe haumaru, celluloid, waikano , pesticides, whakarewa kakara, whakahinuhinu papanga, etc.
- Hei plasticizer mo te cellulose ester, te tote me te rapa taiao, te polystyrene; ki te hanga i te polyvinyl chloride me ona copolymers i te makariri mo te whakahiato pararopi, te katote whiriwhiri i nga taputapu hiko, te whakarewa, te ngarara, te plasticizers, te hau chromatography wai noho (te teitei o te whakamahi i te pāmahana 100 ℃, te whakarewa he acetone, benzene, dichloromethane, ewaro), te pupuri me te whakawehenga o te haunga, te whakangao me te whakawehenga. pūhui hāora (waipiro, aldehydes, ketone, hākawa, aha atu).
