Waa maxay faa'iidooyinka iswaafajinta p-hydroxyacetophenone iyo polyols?

Iswaafajinta u dhaxaysap-hydroxyacetophenonepolyols-ku waxay bixiyaan faa'iidooyin dhowr ah oo ku jira codsiyo kala duwan. Waa kuwan qaar ka mid ah faa'iidooyinka muhiimka ah:

Milmida:p-HydroxiacetophenoneWaxay muujisaa milmi aad u fiican oo ku jirta polyols-ka, taasoo sahlaysa in lagu daro qaacidooyinka. Waxay si fudud ugu milmi kartaa nidaamyada polyol-ka biyaha iyo kuwa aan biyaha lahayn labadaba, taasoo u oggolaanaysa isku-darka isku-dhafka ah iyo qaybinta isku midka ah ee maaddada oo dhan.

Shaqada falcelinta: p-Hydroxyacetophenone wuxuu leeyahay koox shaqeyneysa oo falcelis ah, kooxda hydroxyl (OH), kuwaas oo ka qayb qaadan kara falcelisyada kiimikada ee kala duwan. Tani waxay ka dhigaysaa mid la jaan qaadi karta polyols, kuwaas oo sidoo kale ka kooban kooxo hydroxyl ah. Dabeecadda falcelinta ee p-hydroxyacetophenone waxay u suurtagelineysaa inay ka qayb qaadato falcelisyada isku xirka, taasoo keenta sameynta shabakadaha polymer-ka oo leh sifooyin la xoojiyay.

Nidaamyada la sawiri karo:p-Hydroxiacetophenonewaxaa badanaa loo isticmaalaa sidii sawir-qaade nidaamyada sawir-qaadista. Marka la kulmo UV ama iftiin muuqda, waxay maraan sawir-qaadis si ay u abuuraan xagjirro xor ah, kuwaas oo bilaaba falcelinta isku-xidhka ama isku-xidhka. Iyadoo la isku darayo p-hydroxyacetophenone iyo polyols, waxaa suurtagal ah in la sameeyo agab sawir-qaadis ah sida dahaarka, dhejiska, iyo isku-dhafka ilkaha. Iswaafajinta u dhaxaysa p-hydroxyacetophenone iyo polyols waxay hubisaa sawir-qaadis hufan iyo isku-xidhka, taasoo horseedaysa habab daaweyn degdeg ah oo la xakameeyey.

Sifooyinka antioxidant-ka: p-Hydroxyacetophenone wuxuu muujiyaa sifooyin antioxidant ah, kuwaas oo ka faa'iideysan kara nidaamyada ku salaysan polyol. Hababka oksaydheynta waxay sababi karaan burbur iyo luminta sifooyinka walxaha waqti ka dib. Iyadoo lagu darayo p-hydroxyacetophenone polyols, dhaqdhaqaaqa antioxidant-ka wuxuu gacan ka geystaa joojinta falcelinta oksaydhka, isagoo ilaalinaya hufnaanta iyo waxqabadka maaddada.

Kala Duwanaanshaha: Iswaafajinta u dhaxaysa p-hydroxyacetophenone iyo polyols waxay u oggolaanaysaa kala duwanaansho sameynta alaabooyin kala duwan. Waxaa loo isticmaali karaa codsiyo kala duwan, oo ay ku jiraan xumbo polyurethane ah, resins thermosetting, dahaarka, iyo alaabada daryeelka shaqsiyeed. Awoodda lagu isku dari karo p-hydroxyacetophenone iyo polyols kala duwan waxay bixisaa dabacsanaan ku habboonaanta sifooyinka walxaha ugu dambeeya si loo daboolo shuruudaha gaarka ah.

Xasilloonida: Polyols waxaa loo yaqaanaa xasilloonidooda, isla markaana la jaanqaadida p-hydroxyacetophenone si weyn uma saamayso xasilloonidooda asalka ah. Ku darista p-hydroxyacetophenone polyols ma wax u dhimayso cimrigooda kaydka ama ma keento burbur degdeg ah, taasoo hubinaysa xasilloonida muddada dheer ee alaabada la sameeyay.

Marka la soo koobo, iswaafajinta u dhaxaysa p-hydroxyacetophenone iyo polyols waxay bixisaa faa'iidooyin sida milmida, shaqeynta falcelinta, sawir-qaadista, sifooyinka antioxidant-ka, kala-duwanaanshaha, iyo xasilloonida. Faa'iidooyinkani waxay ka dhigayaan qayb qiimo leh oo ku jirta codsiyada kala duwan, iyagoo kor u qaadaya waxqabadka iyo sifooyinka nidaamyada ku salaysan polyol.
