Elastomer-ka Polyurethane waa nooc ka mid ah walxaha si weyn loo isticmaalo, wuxuu leeyahay dabacsanaan wanaagsan, cimri dherer iyo iska caabin xirasho, sidaa darteed si weyn ayaa loogu isticmaalaa dhammaan qaybaha nolosha. Mid ka mid ah walxaha muhiimka ah ee soo saarista elastomer-ka polyurethane waa isticmaalka kaaliyayaasha dardargeliya falgallada kiimikada inta lagu jiro sameynta walxaha ugu dambeeya. Kaaliyayaashani waxay muhiim u yihiin xakamaynta habka polymerization-ka, hubinta in sifooyinka la rabo ee elastomer-ka la gaaro. Kaaliyeyaasha kala duwan ee la heli karo, MXC-A33 waxay leedahay hal-abuur gaar ah oo loo isticmaali karo noocyo badan oo ah xumbo polyurethane iyo elastomers.
Waa maxayMXC-A33?
MXC-A33 waa kateetar polyurethane ah oo kor u qaada falcelinta u dhaxaysa polyols iyo isocyanates, kuwaas oo ah qaybaha ugu muhiimsan ee walxaha polyurethane. Kateetarku wuxuu ka kooban yahay 33% TEDA (triethylene diamine) iyo 67% DPG (monoconjugated dipropylene glycol). Qaaciddadan gaarka ah waxay bixisaa waxqabad wanaagsan oo ku saabsan soo saarista xumbo polyurethane iyo elastomers.
- TEDA (Triethylenediamine): Kaaliye amine tertiary ah oo aad waxtar u leh oo kor u qaada falcelinta jelling ee u dhaxaysa kooxaha hydroxyl iyo isocyanate.
- DPG (Dipropylene Glycol oo isku xiran): Dareeraha ka caawiya yaraynta daxalka iyo kor u qaadida isku darka agabka, taasoo hubinaysa hab-raac falcelin siman.
Codsiga Polyurethane Elastomers
MXC-A33 si weyn ayaa loogu isticmaalaa soo saarista polyurethane elastomers sababtoo ah saameynteeda dheellitiran ee katalytic-ga, taas oo hubinaysa in fal-celinta polymerization-ku ay ku dhacdo heer la xakameeyey. Fal-celintan la xakameeyey waxay muhiim u tahay soo saarista elastomers-ka leh sifooyinka farsamada ee la rabo sida dabacsanaanta, xoogga jiidista iyo iska caabbinta xirashada.
Kaaliyayaashani waxay kor u qaadaan sameynta qaab-dhismeedyada isku-xidhka polymer-ka ee isku-dhafan, kuwaas oo dabooli kara waxqabadka elastomer-ka marka loo eego codsiyada adag. Elastomer-yada Polyurethane ee laga sameeyay MXC-A33 waxaa si caadi ah loogu isticmaalaa qaybaha baabuurta, duubayaasha warshadaha, iyo shaabadadaha waxqabadka sare leh, kuwaas oo baahiyo badan saaraya cimri dhererkooda iyo dabacsanaantooda.
Gunaanad
Isticmaalkakiciyeyaasha polyurethaneSida MXC-A33 ee wax soo saarka elastomer-ka waa qodob muhiim ah oo lagu hubinayo waxqabadka iyo isku halaynta agabka. Isku-darka gaarka ah ee TEDA iyo DPG wuxuu ka dhigayaa mid aad waxtar u leh labadaba codsiyada xumbo iyo elastomer-ka, taasoo u suurtagelinaysa soosaarayaasha inay soo saaraan badeecooyin tayo sare leh oo waara oo loogu talagalay warshado kala duwan.
