Tsananguro pfupi:

Pfupiso yeChigadzirwa

Phthalic Anhydride (PA) chinhu chakakosha chemakemikari eorganic, chinonyanya kugadzirwa ne oxidation ye ortho-xylene kana naphthalene. Inoratidzika se crystalline solid chena ine hwema hushoma hunotsamwisa. PA inoshandiswa zvakanyanya mukugadzira ma plasticizers, unsaturated polyester resins, alkyd resins, dyes, uye pigments, zvichiita kuti ive chinhu chakakosha muindasitiri yemakemikari.

Zvinhu Zvikuru

• Kukurumidza Kushanda:PA ine mapoka eanhydride, ayo anokurumidza kusangana nealcohols, amines, nezvimwe zvinhu kuti zvigadzire maesters kana maamides.
• Kunyunguduka Kwakanaka:Inonyungudika mumvura inopisa, maalcohols, ethers, nezvimwe zvinonyungudutsa zvakasikwa.
• Kugadzikana:Yakasimba kana yakaoma asi inonyungudika zvishoma nezvishoma kuita phthalic acid kana paine mvura.
• Kuchinja-chinja:Inoshandiswa mukugadzirwa kwemhando dzakasiyana dzemakemikari, zvichiita kuti ishande zvakasiyana-siyana.

Mashandisirwo

1. Zvigadzirwa zvepurasitiki:Inoshandiswa kugadzira maester e-phthalate (semuenzaniso, DOP, DBP), ayo anoshandiswa zvakanyanya muzvigadzirwa zvePVC kuwedzera kuchinjika uye kugona kushandiswa.
2. MaResins ePolyester Asina Kuzara:Inoshandiswa mukugadzira fiberglass, machira, uye manamati, ichipa hunhu hwakanaka hwemakanika uye inodzivirira makemikari.
3. MaResin eAlkyd:Inoshandiswa mumapendi, machira, uye mavarnish, zvichiita kuti irambe yakanamatira uye ichipenya zvakanaka.
4. Madhayi nePigments:Inoshanda sechikamu chepakati mukugadzirwa kwemavara nemavara eanthraquinone.
5. Mamwe Mashandisirwo:Inoshandiswa mukugadzira mishonga yemishonga, mishonga yezvipembenene, uye zvinonhuhwirira.

Kurongedza & Kuchengeta

• Kurongedza:Inowanikwa mumabhegi e25 kg/bhegi, 500 kg/bhegi, kana matani. Sarudzo dzekurongedza dzakagadzirirwa iwe dzinowanikwa kana ukakumbira.
• Kuchengetera:Chengeta munzvimbo inotonhorera, yakaoma, uye ine mhepo inofefetera zvakanaka. Dzivisa kusangana nehunyoro. Tembiricha inokurudzirwa yekuchengetedza: 15-25℃.

Kufunga Nezvekuchengetedza & Zvakatipoteredza

• Kutsamwiswa:PA inogumbura ganda, maziso, uye kufema. Midziyo yakakodzera yekudzivirira (semuenzaniso, magirovhosi, magirazi ekudzivirira, marespirator) inofanira kupfekwa panguva yekubata.
• Kubvira:Inobvira asi haibatike zvakanyanya. Chengeta kure nemoto wakavhurika uye tembiricha yakakwira.
• Kukanganiswa Kwezvakatipoteredza:Rasa marara zvichienderana nemitemo yenharaunda yemuno kudzivirira kusvibiswa.

Taura nesu

Kuti uwane rumwe ruzivo kana kukumbira sampuro, ndapota taura nechikwata chedu chekutengesa. Takazvipira kupa zvigadzirwa zvemhando yepamusoro uye sevhisi yakanaka kwazvo!
