Dalabyada PMDETA (MXC-5)falgal kicitaan oo dheellitiraninta u dhaxaysa falgallada xumbo iyo jelling, taasoo hubinaysa xakamaynta habaynta oo aad u fiican. Hawlgalkeeda sare wuxuu u oggolaanayaawaqtiyo daaweyn degdeg ahiyoqaab-dhismeedka unugyada isku midka ah, taasoo gacan ka geysaneysa sifooyinka farsamada iyo kulaylka wanaagsan ee alaabada polyurethane.
Adeegsiga PMDETA ee Warshadaha Polyurethane
1. Xumbo adag oo Polyurethane ah
PMDETA (MXC-5) waxaa si weyn loogu isticmaalaa wax soo saarka aaladaha dila jeermiska dilaxumbo adag oo polyurethane ahhalkaas oo ay ku sii xoojinaysohufnaanta afuufiddaiyomidnimada unugyadaXumbadahan waxaa badanaa loo isticmaalaa:
- Buufin xumbo polyurethane ah (SPF)dahaarka
- Nidaamyada dahaarka qaboojiyaha iyo qaboojiyaha
- Saamiyada guddiga iyo wax soo saarka guddiyada joogtada ah
- Dahaarka tuubooyinka iyo qalabka
Awooddeeda sare ee kicinta ayaa taageerta labadababiyo-qariyeyiyoHFO-burburaynidaamyada, taasoo ka dhigaysa mid ku habboon qaacidooyinka casriga ah ee qiiqa yar.
2. Xumbo dabacsan oo yar yar
In codsiyada baabuurta iyo baakadaha, PMDETA waxay u dhaqantaa sidii kiciye xumbo wax ku ool ah oo kor u qaadaprofiles kor u kac simaniyoQaab-dhismeedka unugyada oo fiican oo joogto ahWaxay ka caawisaa soosaarayaasha inay gaaraan agab polyurethane ah oo fudud laakiin waara oo loo isticmaaloMaqaarka dashboard-ka, kuraasta madaxa, iyo qaybaha nuugaya saameynta.
3. Qalabka Heerkulka, Elastomers, iyo Dahaadhka
Marka laga reebo xumbada polyurethane, PMDETA waxay u shaqeysaa sidiiligand-ka badan ama katalyste-ka wada-shaqaynta leh in polymerization iyo falcelinta daaweyntaWaxay door muhiim ah ka ciyaartaa horumarintathermoplastics, elastomers, iyo dahaarka waxqabadka sare leh, awood u siinaya polymers-ka inay la shaqeeyaandabacsanaan loo habeeyay, dhegdheg, iyo iska caabin kiimiko.
Muhiimadda Warshadaha ee PMDETA (MXC-5)
Kala duwanaanta PMDETA waxay ku jirtaa qaabkeedadoor laba-geesood ah sida ligand iyo kiciyahaWaxay la jaanqaadi kartaa ayoonnada birta ah si loo fududeeyo polymerization, isku xidhka, iyo daaweynta falcelinta - tallaabooyinka muhiimka ah ee soo saaristanidaamyada polyurethane ee horumarsaniyopolymers gaar ah.
Kiimikada polyurethane, waxtarka sare ee PMDETA wuxuu u oggolaanayaa soosaarayaasha inay:
- Yaree qiyaasta kicinta adigoon wax u dhimin falcelinta
- Soo gaabi wareegyada wax soo saarka iyo waqtiyada daaweynta
- Hagaaji qaab-dhismeedka xumbo iyo tayada dusha sare
- Gaaritaanka qiiqa oo hooseeya iyo xakamaynta urta oo wanaagsan
La jaanqaadideeda nidaamyada kala duwan ee polyol iyo isocyanate ayaa sidoo kale taageertadeegaanka u fiican iyo tamarta ku habboonsoo saarista xumbo, iyadoo la jaanqaadaysa baahida sii kordheysa eeagabka dahaarka waara.
Faa'iidooyinka Isticmaalka PMDETA (MXC-5)
- Firfircooni sare lehlabadaba falcelinta jelling iyo afuufidda
- Milmi aad u fiicanisku darka polyol iyo dareere kale
- Xasillooni xumbo oo la xoojiyayiyo isku mid ahaanshaha
- Kala duwanaansho codsi oo ballaaranxumbo, elastomers, iyo dahaarka
- Ku habboon qaacidooyinka ku salaysan HFO, yaraynta saameynta deegaanka
Astaamahani waxay ka dhigayaan MXC-5 mid ka mid ah kiciyayaasha la doorbido ee soo saarayaasha ujeedadoodu tahay inaywanaajiya waxqabadka, yaree kharashka, iyo hubinta dabacsanaanta qaacidada.
