Nadiifinta sareeysa ee isopropyl acetate Solvent 99.5%

Gaar ahaan: 180kg / durbaan

isopropyl acetate, oo sidoo kale loo yaqaan 2-propyl acetate ama acetic acid isopropyl ester, waa dareere aan midab lahayn, oo ololaya oo leh miro sifo leh, ur u eg pear. Alaabtayada qaaliga ah waxay ku gaadhaan 99.5% nadiif ah, iyagoo soo bandhigaya waxqabad gaar ah oo loogu talagalay dahaarka, daabacaadda khadadka, xabagta, iyo codsiyada warshadaha gaarka ah ee u baahan uumiga degdega ah iyo xalalka aad u fiican.

Sida dareeraha ester-ka-yar ee miisaan-yar, isopropyl acetate wuxuu isku daraa sifooyin jireed oo wanaagsan oo ka soocaya ester-yada kale ee acetate. Kooxda isopropyl ee laan waxay yaraynaysaa xiisadda dusha sare waxayna wanaajisaa laqabsiga resins polar iyadoo la ilaalinayo isbeddel dhexdhexaad ah (barka karkarinta 88-89°C). Isku-dheelitirkan u dhexeeya heerka uumi-baxa iyo awoodda xalinta ayaa si gaar ah qiimo ugu leh codsiyada u baahan qalajinta degdega ah iyada oo aan waxyeello loo geysan samaynta filimka ama dhejinta.

Warshadaha rinjiyada iyo rinjiga waxay ka dhigan yihiin qaybta codsiga aasaasiga ah ee isopropyl acetate, halkaas oo ay u adeegto sida dareeraha firfircoon ee nitrocellulose, acrylic, vinyl, iyo resins epoxy. Sifooyinkeeda uumi-baxa degdega ah waxay taageertaa khadadka wax-soo-saarka xawaaraha sare leh ee daahan baabuurta, alwaax dhammeeya, iyo rinjiga dayactirka warshadaha. Iska caabbinta buluuga ah ee wanaagsan ee xaaladaha qoyan waxay hubisaa tayada dusha sare ee joogtada ah, halka urta khafiifka ah ay hagaajinayso aqbalaadda goobta shaqada marka loo eego beddelka udgoonka.

Daabacaadda qaababka khad, IPA waxay u shaqeysaa sidii dareere fure u ah galka flexographic iyo gravure, taasoo u sahlaysa qalajinta degdega ah ee mashiinnada xawaaraha sare leh iyadoo la ilaalinayo horumarka midabka wanaagsan iyo ku dheggan substrate-ka. Warshadaha xabagta waxay u isticmaalaan qaabaynta xabagta cadaadiska-xasaasiga ah iyo sida dareeraha nadiifinta ee qalabka codsiga.

Codsiyada dheeraadka ah waxay ka kooban yihiin isticmaalka sida dareeraha soo saarista daawooyinka iyo alaabta dabiiciga ah, qayb ka mid ah qaababka qurxinta iyo udgoonka, iyo dareeraha habka kiimikada isku dhafan. Muuqaalka sunta ah ee wanaagsan iyo biodegradability waxay taageertaa isticmaalkeeda codsiyada halka tixgelinta badbaadada deegaanka iyo shaqaalaha ay muhiim tahay.

99.5% isopropyl acetate saafi ah waxay la kulantaa qeexitaanno adag oo loogu talagalay acidity hoose, content biyaha ugu yar, iyo midabka kantaroolka (Pt-Co), hubinta waxqabadka la isku halayn karo ee soosaarayaasha dahaarka, soosaarayaasha khadadka, soosaarayaasha koollada, iyo soosaarayaasha kiimikada khaaska ah ee u baahan dareeraha ester-ka sare ee u baahan codsiyada degdega ah.

Shirkaddayadu waxay si qoto dheer ugu hawlan tahay warshadaha kiimikada waxayna inta badan wax ka qabataa noocyo kala duwan oo alaabta ceeriin kiimikaad ah sida surfactants, kiimikooyinka ganaaxa ee saliidda, alaabta ceeriin ee aasaasiga ah, dareerayaasha organic, dhexdhexaadinta dawooyinka iyo sunta cayayaanka, wakiilada daaweynta biyaha, iyo cuntada lagu daro. Alaabooyinkeeda ayaa si weyn looga isticmaalaa warshado kala duwan.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
