PGMEA Nadaafadda Sare ee Propylene Glycol Methyl Ether Acetate

Faahfaahinta alaabta

Propylene Glycol Monomethyl Ether Acetate (PMA ama PGMEA) waa dareere aan midab lahayn, ur leh oo heer sare ah oo dareere ah oo leh qaacidada kiimikada C6H12O3 iyo miisaan kelli ah 132.16. Lambarkeeda CAS waa 108-65-6. Qaab dhismeedka molecular ee PMA wuxuu ka kooban yahay curaarta ether, kooxaha kaarboonyl, iyo kooxaha ester-ka, kuwaas oo ka dhigaya mid aad waxtar ugu leh kala dirida walxaha polar iyo non-polar. PMA waxaa si weyn loogu isticmaalaa goobaha warshadaha, gaar ahaan dahaarka, khadadka, wax soo saarka elektarooniga ah, iyo dheeha.

Codsiga alaabta

Propylene glycol methyl ether acetate waa dareere aan khatar ahayn oo leh kooxo badan oo shaqeynaya. Codsigeeda inta badan waxay diiradda saaraan warshadaha iyo warshadaha kiimikada, gaar ahaan ay ku jiraan dhinacyada soo socda:

1. Dahaarka iyo warshadaha rinji: Sida dareere ah ee daahan-dhamaadka sare iyo khad, waa ku haboon yahay esters amino methyl, vinyl, polyester, cellulose acetate, alkyd resins, resins acrylic, epoxy resins, iyo nitrocellulose in industry ee dahaarka sida kaaliyaha rinjiga TV, taas oo ka caawisaa in la wanaajiyo daahan sida awoodda rinjiga sare sida TV-ga. rinjiga, iyo diyaarada rinji sida dareereyaal iyo wakiilo siman, kor u qaada dahaarka waxqabadka, dareere, iyo adhesion.

2. Electronics iyo warshadaha semiconductor: Waxaa loo isticmaalaa sida a TFT-LCD darye iska caabin ah, dareere saarista photoresisist, wakiilka ka saarida, wakiilka IC nadiifinta, photoresist saarista baffer, iyo etchant habka wax soo saarka ee photoresists. Alaabooyinka heerka elegtaroonigga ah waxaa loo isticmaalaa sidii walxaha nadiifinta LCD iyo alaabada kale ee kiimikaad ee looga baahan yahay warshadaha elektiroonigga ah. Waa kiimiko geeddi-socod oo muhiim ah soo saarista crystal dareeraha iyo semiconductor.

3. Khadadka iyo warshadaha daabacaadda: Waxa loo isticmaalaa sida dareere loo isticmaalo rinjiyada, khadyada, iyo faashashka, taas oo ka caawisa in alaabtan ay milmaan oo ay si fiican u shaqeeyaan, waana dareere aad u fiican oo daabacaadda khdadka.

4. Warshadaha Dharka: Waxaa loo isticmaalaa sida dareere loogu talagalay dheeha dharka iyo saliidaha dunta, ka caawinta dheeha inay milmaan oo si fiican ugu firdhiyaan dunta.

5. Codsiyada kale ee warshadaha: Waxaa loo isticmaalaa sida dareere loogu talagalay nadiifiyeyaasha iyo dahaarka, ka saarida khadadka, ka caawinta in laga saaro wasakhda dusha sare iyo dahaarka duugga ah. Waxaa loo isticmaalaa sidii balaastiiste beerta balaastikada ah, ka caawinta hagaajinta dabacsanaanta, xoojinta, iyo xoogga balaastikada. Waxaa loo isticmaalaa sida dareere loogu talagalay cayayaanka, ka caawinta cayayaanka inay kala firdhiyaan oo ay si fiican u galaan. Warshadaha maqaarka, waxaa loo isticmaalaa sida dareeraha binder, kaas oo hagaajin kara jilicsanaanta iyo ilaalinta iftiinka wanaagsan ee maqaarka.

Xaaladda kaydinta

Propylene glycol methyl ether acetate waa in lagu kaydiyaa bakhaar gaar ah oo qabow, hawo fiican leh, oo qalalan, kana fog ilaha dabka, ilaha kulaylka, iyo iftiinka qorraxda tooska ah. Weelasha waa in la xidhaa, walaxdana waa in si gooni ah loo kaydiyaa marka laga reebo oksaydhiyeyaasha, acids, iyo saldhigyada.

Shuruudaha kaydinta gaarka ah waa sida soo socota: Xaaladaha deegaanka kaydinta waa inay ahaadaan sida heerkulka goobta kaydinta uusan ka badnayn 30 ° C (ilo wareedyo qaarkood waxay ku talinayaan inaysan dhaafin 37 ° C). Ka fogow iftiinka qorraxda tooska ah iyo jawiga heerkulka sare si aad uga hortagto uumiga degdega ah ama khataraha badbaadada. Bakhaarku waa in lagu rakibaa qalabyada lidka-static-ka ah, tas-hiilaadka ilaalinta hillaaca, iyo nalalka aan qarxin iyo qalabka hawada si loo hubiyo wareegga hawada iyo ka saarida uumiga suurtagalka ah ee waqtiga ku habboon.
