Mawu Oyamba
methyl hydrogen azelate, yomwe imadziwikanso kuti polycarboxylate, ndiyofunikira kwambiri polima. Lili ndi zotsatirazi:
1. Thupi: methyl hydrogen azelate ndi madzi achikasu kapena opepuka, osungunuka bwino, amasungunuka m'madzi, mowa ndi zosungunulira organic.
2. Chemical katundu: methyl hydrogen azelate ndi ester pawiri ndi mkulu bata ndi kukana mankhwala. Itha kukhala hydrolyzed kukhala azelaic acid ndi methanol.
Kugwiritsa ntchito kwakukulu kwa methyl hydrogen azelate ndi:
1. Kukonzekera kwa polima: methyl hydrogen azelate ikhoza kupangidwa ndi ma monomers ena kuti ikonzekere ma polima apamwamba kwambiri. Ma polima awa ali ndi zinthu zabwino kwambiri ndipo amatha kugwiritsidwa ntchito m'mafakitale osiyanasiyana monga zokutira, zomatira, mapulasitiki, ulusi, ndi zina.
2. Surfactant: methyl hydrogen azelate angagwiritsidwe ntchito ngati emulsifier, dispersant ndi wetting agent, amagwiritsidwa ntchito kwambiri mu zodzoladzola, zotsukira ndi zinthu zosamalira anthu ndi zina.
Njira zopangira methyl hydrogen azelate makamaka ndi izi:
1. Transesterification reaction: transesterification reaction imachitika ndi nonyl mowa ndi methyl formate pamaso pa asidi chothandizira kupeza methyl hydrogen azelate.
2. Direct esterification reaction: esterification ya nonanol ndi kupanga pansi pa zochita za asidi catalyst kupanga methyl hydrogen azelate.
Zindikirani zachitetezo chotsatirachi mukamagwiritsa ntchito methyl hydrogen azelate:
1. methyl hydrogen azelate imakwiyitsa ndipo iyenera kutsukidwa nthawi yomweyo ikakhudza khungu ndi maso.
2. Pewani kulowetsa mpweya wa methyl hydrogen azelate ndikuugwiritsa ntchito pamalo olowera mpweya wabwino.
3. methyl hydrogen azelate ili ndi kawopsedwe kakang'ono, koma kuwonetsa kwanthawi yayitali komanso kwakukulu kumatha kukhudza thanzi, ndipo kuwonetseredwa mopitirira muyeso kuyenera kupewedwa.
4. Posunga ndi kutumiza methyl hydrogen azelate, isungeni kumoto ndi kutentha kwakukulu kuti mupewe ngozi yoyaka ndi kuphulika.
Chonde dziwani kuti musanagwiritse ntchito methyl hydrogen azelate kapena mankhwala aliwonse, muyenera kuwerenga mosamala ndikutsata njira zotetezera.
