Ukusetshenziswa kwe-HTPB kuma-Sealants kanye nama-Potting Compounds
Iyini i-HTTPB kanye nezakhiwo zayo ezihlukile
Ungase uzibuze ukuthi yini eyenza i-HTPB ivelele ezweni lokuvikela ikhaya. I-HTPB, noma i-Hydroxyl-terminated polybutadiene, iyirabha ekhethekile yoketshezi. Isakhiwo sayo samakhemikhali sinamaqembu e-hydroxyl ekugcineni kwamaketanga ayo. La maqembu asiza i-HTPB ukwakha inethiwekhi eqinile enezinhlangothi ezintathu uma uyixuba nezinye izinto. Le nethiwekhi inikeza i-HTPB amandla ayo nokuguquguquka.
I-HTPB ihlala iguquguquka ngisho noma isimo sezulu sibanda ngoba inezinga lokushisa eliphansi lokushintsha kwengilazi elingu--75°C. Akudingeki ukhathazeke ngokuthi ama-sealant akho azophuka ebusika. I-HTPB iphinde imelane namakhemikhali amaningi, amafutha, ama-asidi, kanye nezisekelo. Uthola izinto ezihlala isikhathi eside futhi ezivikela ikhaya lakho ezimweni ezinzima.
Icebiso: Uhlobo lwe-HTPB oluwuketshezi lwenza kube lula ukulisebenzisa ekubunjweni nasekufakweni, ngisho nasezindaweni ezinzima.
Kungani i-HTPB Ibalulekile Ngezivalo Nezinhlanganisela Zokubumba
Uma ubheka ukusetshenziswa kwe-HTPB kuma-Sealants kanye nama-Potting Compounds, ubona izinzuzo eziningi ekhaya lakho.
