Indima yePhthalic Anhydride kuShishino lweMichiza

I-anhydride ye-phthalicyinxalenye yemichiza ebalulekileyo edlala indima ebalulekileyo kushishino lwemveliso. Iimpawu zayo eziguquguqukayo zenza ukuba ibe sisithako esibalulekileyo kwimveliso yeemveliso ezahlukeneyo, ukusuka kwiiplastiki kunye neentlaka ukuya kwidayi kunye namayeza. Kule post yebhlog, siza kuphonononga ukusetyenziswa kunye nokubaluleka kwe-phthalic anhydride kwishishini lemichiza.

Enye yezinto eziphambili zokusetyenziswa kwe-phthalic anhydride kukuveliswa kweeplasticizers zephthalate, ezisetyenziselwa ukwenza i-PVC (i-polyvinyl chloride) iguquguquke kwaye ihlale ixesha elide. Ezi plasticizers ziyimfuneko kuluhlu olubanzi lwezicelo, kubandakanywa iingcingo kunye neentambo, umgangatho, kunye nezixhobo zonyango. Ngaphandle kwe-phthalic anhydride, ukuveliswa kwezi zinto zibalulekileyo kuya kuthinteleka kakhulu.

I-Phthalic anhydride ikwasithako esiphambili ekuvelisweni kweereyini zepolyester ezingaxutywanga, ezisetyenziswa kakhulu xa kusenziwa iiplastiki ezomelezwe ngefiberglass. Ezi ntlaka zisetyenziswa kwimizi-mveliso yeemoto, eyokwakha, naselwandle, phakathi kwezinye, ngenxa yokomelela kwazo okubalaseleyo, ukuqina, kunye nokuxhathisa umhlwa. Ngaphandle kwe-phthalic anhydride, ukuveliswa kwezi resins ziyimfuneko akunakwenzeka.

Ukongeza kwiiplastiki kunye neerasi, i-phthalic anhydride isetyenziselwa ukuveliswa kwedayi kunye ne-pigments. Isebenza ngeendidi zeekhemikhali ukwenza iikhompawundi ezinemibala esetyenziswa kwimizi-mveliso yelaphu, iphepha, kunye neplastiki. Ezi dayi kunye nee-pigments ziyimfuneko kwimveliso yoluhlu olubanzi lweemveliso, ukusuka kwimpahla kunye nokupakisha ukuya kwizinto eziprintiweyo kunye nempahla yabathengi.

Ngaphaya koko, i-phthalic anhydride sisithako esibalulekileyo kwimveliso yamayeza athile kunye neekhemikhali zezolimo. Isetyenziswa ekudityanisweni kwamachiza ahlukeneyo kunye nezibulali-zinambuzane, ezinegalelo ekuqhubeleni phambili kwezempilo kunye nezolimo. Ngaphandle kwe-phthalic anhydride, ukuveliswa kwezi khemikhali ziyimfuneko kuya kuba nefuthe elibi.

Ngaphandle kokusetyenziswa kwayo ngeendlela ezininzi, kubalulekile ukuqaphela ukuba i-phthalic anhydride iphakamise inkxalabo malunga neempembelelo zayo ezinokuthi zibe kho kwimpilo kunye nokusingqongileyo. Kubalulekile ukuba abavelisi baphathe kwaye basebenzise i-phthalic anhydride ngokuthembekileyo ukunciphisa iingozi ezinokubakho. Ukongeza, abaphandi kunye nososayensi bahlala bephonononga ezinye iikhompawundi kunye neendlela zokuvelisa ukujongana nale nkxalabo kunye nokudala izisombululo ezizinzileyo.

Ukuqukumbela, i-phthalic anhydride yikhompawundi ebalulekileyo yeekhemikhali eyimfuneko kwishishini lemveliso. Usetyenziso lwayo oluguquguqukayo kwimveliso yeeplastiki, iintlaka, iidayi, amayeza, kunye neekhemikhali zezolimo ziyenza ibe sisithako esibalulekileyo kwiimveliso ezahlukeneyo esizisebenzisa kubomi bethu bemihla ngemihla. Njengoko ishishini liqhubeka nokuvela, kubalulekile ukubeka phambili usetyenziso olunoxanduva noluzinzileyo lwe-phthalic anhydride ukunciphisa iimpembelelo ezinokubakhona kwimpilo yabantu kunye nokusingqongileyo.
