K'hemistring ea indasteri ea sejoale-joale, li-additives tse khethehileng le li-crosslinking agents li bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso, ho tšoarella le botsitso ba thepa. Har'a lik'hemik'hale tsena tse sebetsang,Adipic Dihydrazide (ADH)e fumane bohlokoa bo boholo ho pholletsa le lipente, likhomaretsi, li-resin tse thehiloeng metsing le litsamaiso tsa polymer.
Adipic Dihydrazide ke setlhare se sebetsang hantle haholo.sesebelisoa sa ho hokahanya le ho eketsa phekoe sebelisoa haholo lits'ebetsong tse tsamaisoang ke metsi. E eketsa matla a filimi, e ntlafatsa khanyetso ea lik'hemik'hale, 'me e eketsa ho tšoarella ha lipente le li-emulsion. Ha liindasteri li ntse li tsoela pele ho fetohela ho li-formulations tse nang le tšireletso tikolohong, tse nang le VOC e tlase metsing, ADH e fetohile thepa ea bohlokoa e tšehetsang phetoho ena.
Sengoloa sena se hlahloba hore na Adipic Dihydrazide ke eng, hore na e sebetsa joang, litšobotsi tsa eona tsa lik'hemik'hale, lits'ebetso tse kholo, melemo le mekhoa ea indasteri.
Boitsebiso ba Lik'hemik'hale ba Adipic Dihydrazide
Adipic Dihydrazide ke motsoako oa lintho tse phelang o nkiloeng ho adipic acid. Sebopeho sa eona sa limolek'hule se na le lihlopha tse peli tse sebetsang tsa hydrazide, tse e fang ts'ebetso e matla lits'ebetsong tsa ho kopanya li-polymer.
Litšobotsi tsa Motheo:
· Foromo ea lik'hemik'hale: C₆H₁₄N₄O₂

4. Ntlafatso ea Botsitso ba Thempereichara
ADH e thusa ho roala ho boloka tshebetso tlasa diphetoho tsa mocheso.
Adipic Dihydrazide ka har'a Liaparo tse Thehiloeng Metsing
E 'ngoe ea lits'ebetso tsa bohlokoa ka ho fetisisa tsa ADH ke holiphahlo tse tsamaisoang ke metsi, haholo-holo mefuteng e nang le VOC e tlase le e sa senyeheng tikoloho.
Melemo ea Liaparo:
· Ho tšoarella ha filimi ho ntlafetse
· Ho boloka khanya e betere
· Ho khomarela ho matlafalitsoeng

· Ho hasana ha polyurethane
· Litsamaiso tsa Latex
4. Ho Tšoarella ho Ntlafetseng
E eketsa nako ea bophelo ba sehlahisoa le ts'epo ea ts'ebetso.
Meeli ea ADH
Ho sa tsotellehe melemo ea eona, ADH e na le mefokolo e meng:
· E hloka taolo e nepahetseng ea sebopeho
· Reactivity e itšetlehile ka lihlopha tse sebetsang tsa polymer
· Meeli e fokolang ea ho qhibiliha metsing
Moralo o nepahetseng oa sebopeho o bohlokoa bakeng sa ts'ebetso e ntle ka ho fetisisa.
Bohlokoa ba Indasteri
Adipic Dihydrazide e ntse e ba bohlokoa haholo ho:
· Thepa e tala ea moaho
· Litsamaiso tsa ho koahela tse tsamaisoang ka metsi
· Likhomaretsi tse sebetsang hantle
· Metswako ea indasteri e amohelang tikoloho
Karolo ea eona e lebelletsoe ho hola ha liindasteri li ntse li leba litharollong tsa k'hemistri tse tsitsitseng.
Mekhoa ea Nts'etsopele ea Nakong e Tlang
Bokamoso ba ADH bo ho:
1. Mekhoa ea ho Koahela e Sireletsang Tikoloho
Keketseho ea tlhoko ea lipente tse se nang VOC e tla susumetsa tšebeliso.
2. Ho hokahanya ha Polymer e Tsoetseng Pele
Mekhoa e mecha ea motsoako e kopanyang ADH le lintho tse nyenyane.
3. Lisebelisoa tsa indasteri tse sebetsang hantle
Litlhoko tse ntlafetseng tsa ho tšoarella makaleng a kaho le a likoloi.
Adipic Dihydrazide ke sesebelisoa se sebetsang hantle haholo sa ho kopanya lintho tse fapaneng se sebelisoang haholo lits'ebetsong tsa sejoale-joale tsa polymer tse thehiloeng metsing. Bokhoni ba eona ba ho ntlafatsa matla a filimi, ho hanyetsa lik'hemik'hale le ho tšoarella bo etsa hore e be ea bohlokoa ho koaheleng, likhomaretsing le lits'ebetsong tsa indasteri.
Ha liindasteri li ntse li tsoela pele ho fetohela ho ea mefuteng e tsitsitseng le e sireletsang tikoloho, ADH e tla bapala karolo e ntseng e hola lisebelisoa tse sebetsang hantle tsa moloko o latelang.
