Diisocyanate (DDI) imhando yakasiyana ye aliphatic diisocyanate ine musana we 36 carbon atom dimer fatty acid. Chimiro ichi chinopa DDI kuchinjika uye kunamira zviri nani kupfuura mamwe aliphatic isocyanate. DDI ine hunhu husina chepfu, haina yero, inonyunguduka mu organic solvents dzakawanda, isinganyanyi kubatwa nemvura uye ine viscosity shoma. DDI imhando yemabasa maviri. Isocyanate, inogona kushanda ne hydrogen compounds mbiri kana kupfuura kugadzira polymer. DDI inogona kushandiswa mu solid rocket propellant, finishing fabric, bepa, dehwe uye jira rekudzivirira, treatment yehuni yekuchengetedza, electrical potting uye kugadzirira special properties ye polyurethane (urea) elastomers, adhesive uye sealant, nezvimwewo.

Muindasitiri yeMachira, DDI inoratidza kushandiswa kwakanaka kwazvo mukudzivirira mvura uye kunyorovesa machira. Hainyanyi kubatwa nemvura kupfuura aromatic isocyanates uye inogona kushandiswa kugadzira emulsions dzakagadzikana dzemvura.

Kushandiswa kwe0.125%DDI kunoita kuti jira rive rakapfava kwenguva refu; Machira anorapwa ne cationic softeners asingagari kwenguva refu ane kushanduka kwakafanana mushure mekusukwa ka26. Mushonga unobvisa mvura uchishandisa 1%DDI une mhedzisiro yakafanana kana iri nani yekubvisa mvura semushonga unobvisa mafuta wepyridine water repellent (AATCC test).

DDI inogona kuvandudza mashandiro emachira anodzivisa mvura uye anodzivisa mafuta. Kana ikashandiswa pamwe chete, DDI inogona kuvandudza zvakanyanya hunhu hwemachira anodzivisa mvura uye anodzivisa mafuta.

Ongororo dzemurabhoritari nedzemumunda dzakaratidza kuti DDI inodzivirira kugezwa nekucheneswa zviri nani pane fluoride kana zvimwe zvinowedzerwa mumachira zvakaita se antistatic agents.

DDI, yakagadzirwa kubva kumafuta edimer, imhando ye isocyanate yakasvibira, inogona kudzoserwazve. Kana ichienzaniswa ne isocyanate yepasi rose TDI, MDI, HDI neIPDI, DDI haina chepfu uye haikurumidzi. Nekufarirwa kwezvinhu zve dimeric acid muChina uye vanhu vari kuramba vachitarisa hupfumi hwekuchengetedza zvakatipoteredza husina kabhoni yakawanda uye budiriro inoenderera mberi, kukosha kwekushandisa zvinhu zve bio-renewable kugadzira DDI kwave kuoneka zvishoma nezvishoma, izvo zvine kukosha kwakakosha mukusimudzira indasitiri ye polyurethane.
