Astaamaha

DB 75 waa kulayl dareere ah iyo nidaamka xasilinta iftiinka loogu talagalay polyurethane

Codsiga

DB 75 waxaa loo isticmaalaa polyurethane sida Reaction Injection Molding (RIM) polyurethane iyo thermoplastic polyurethane (TPU). Isku darka ayaa sidoo kale loo isticmaali karaa codsiyada dhejiska ah iyo dhejiska, daaha polyurethane ee taarpaulin iyo sagxadda sagxadda iyo sidoo kale maqaarka synthetic.

Tilmaamaha/faa'iidooyinka

DB 75 waxay ka hortagtaa nabaad-guurinta, iftiinka iyo cimilada ay keentay
ee alaabta poliurethane sida kabo kabo, qalab iyo albaabbada, giraangiraha isteerinka, dabool daaqadaha, nasinta madaxa iyo cudud.
DB 75 si fudud ayaa loogu dari karaa nidaamka polyurethane udgoon ama alifbeetada loogu talagalay qaabaynta heerkulbeegga, xumbo isku dhafan oo adag, maqaarka caaryada ku jira, codsiyada dope. Waxaa loo isticmaali karaa alaab dabiici ah iyo midabyo. DB 75 waxay si gaar ah ugu habboon tahay diyaarinta koollada midabka khafiifka ah ee nidaamyada kor ku xusan.
Faa'iidooyinka dheeraadka ah:
fududahay in la shubo, dareere la shubi karo oo u oggolaanaya in si bilaash ah loo maareeyo, qiyaasta tooska ah iyo soo gaabin waqtiga isku darka
dhammaan xirmooyinka dareeraha ah; ma jiro sedimentation of additives in wajiga polyol xitaa heerkulka hoose
adkaysi u exudation / crystallization ee nidaamyada PUR badan

Foomamka badeecada dareere cad oo huruud ah

Tilmaamaha isticmaalka

Heerarka isticmaalka DB 75 waxay u dhexeeyaan 0.2% iyo 1.5%, taas oo ku xidhan substrate iyo shuruudaha waxqabadka codsiga kama dambaysta ah:
Xumbooyin laba qaybood ka kooban oo fal-celin leh 0.6 % - 1.5 %
Xabagta 0.5% - 1.0%
