Tlhaloso ea litlhaku

DB 75 ke sistimi ea metsi e sireletsang mocheso le khanya e entsoeng bakeng sa polyurethanes

Kopo

DB 75 e sebediswa ho polyurethanes tse kang Reaction Injection Molding (RIM) polyurethane le thermoplastic polyurethane (TPU). Motswako ona o ka boela wa sebediswa ho sealant le ho kgomaretsa, ho penteng ya polyurethane hodima tarpaulin le fatshe hammoho le letlalong la maiketsetso.

Likarolo/melemo

DB 75 e thibela ho senyeha ho bakoang ke ts'ebetso, khanya le boemo ba leholimo
ea lihlahisoa tsa polyurethane tse kang lithapo tsa lieta, liphanele tsa lisebelisoa le mamati, mabili a setering, li-capsulating tsa lifensetere, li-rest tsa hlooho le matsoho.
DB 75 e ka eketsoa habonolo lits'ebetsong tsa polyurethane tse nkhang hamonate kapa tse nang le monko o monate bakeng sa li-molding tsa thermoplastic, li-foam tse kopaneng tse se nang le 'mele o tiileng, ho skin ka har'a hlobo, le lits'ebetso tsa dope. E ka sebelisoa ka thepa ea tlhaho le e nang le 'mala o mofubelu. DB 75 e loketse haholo bakeng sa ho lokisa li-pesta tse mebala-bala tse bobebe bakeng sa lits'ebetso tse boletsoeng ka holimo.
Melemo e meng:
ho bonolo ho pompa, mokelikeli o ka tšolohang o lumellang ho sebetsana ntle le lerōle, tekanyo e iketsang le ho khutsufatsa nako ea ho kopanya
sephutheloana sohle sa metsi; ha ho na ho sedimentation ea li-additives karolong ea polyol esita le mochesong o tlase
e hanelang exudation/crystallization lits'ebetsong tse ngata tsa PUR

Mefuta ea sehlahisoa Mokelikeli o hlakileng, o mosehla hanyane

Litaelo tsa tšebeliso

Maemo a tshebediso a DB 75 a pakeng tsa 0.2% le 1.5%, ho itshetlehile ka substrate le ditlhoko tsa tshebetso tsa tshebediso ya ho qetela:
Foam e kopanetsoeng ea likarolo tse peli e arabelang 0.6 % – 1.5 %
Likhomaretsi 0.5% – 1.0%
Litiiso 0.2 % – 0.5 %
Lintlha tse ngata tsa ts'ebetso ea DB 75 lia fumaneha bakeng sa lits'ebetso tse ngata.
