Chiyambi cha ntchito zazikulu za polyether polyols

Polyether polyol ndizofunikira kwambiri zopangira mankhwala, zomwe zimagwiritsidwa ntchito kwambiri popanga mafakitale monga kusindikiza ndi utoto, kupanga mapepala, zikopa zopangira, zokutira, nsalu, mapulasitiki a thovu ndi chitukuko cha mafuta.Kugwiritsa ntchito kwambiri polyether polyol ndikupanga thovu la polyurethane (PU), ndipo polyurethane imagwiritsidwa ntchito kwambiri m'mipando yamkati, zamagetsi, zomangamanga, zida za nsapato, zida zapanyumba, magalimoto ndi zonyamula.Makampani okongoletsera amawongolera kufunikira kwa msika wonse, kutsatiridwa ndi mafakitale omanga, pomwe msika wa zida zapanyumba ndi njanji yothamanga kwambiri idzakhala mizati yofunika kwambiri pakukulitsa kufunikira kwamtsogolo kwa polyurethane.

1. Detergent kapena defoamer

L61, L64, F68 amagwiritsidwa ntchito popanga zotsukira zopangira zokhala ndi thovu lochepa komanso zotsekemera kwambiri;

L61, L81 amagwiritsidwa ntchito ngati defoamer mumakampani opanga mapepala kapena fermentation;

F68 imagwiritsidwa ntchito ngati defoamer pakuyenda kwa magazi kwa makina opangira mtima-mapapo kuti mpweya usalowe.

2. Zothandizira ndi emulsifiers

Ma polyethers ali ndi kawopsedwe kakang'ono ndipo amagwiritsidwa ntchito ngati zopangira mankhwala ndi emulsifiers;amagwiritsidwa ntchito kaŵirikaŵiri popopera pakamwa, m’mphuno, m’maso, m’makutu ndi m’ma shampoos.

3. Wonyowetsa

Ma polyethers ndi othandiza kunyowetsa ndipo angagwiritsidwe ntchito posambira kwa asidi popaka nsalu, kukula kwa zithunzi ndi electroplating, pogwiritsa ntchito F68 mu mphero za shuga, shuga wambiri amatha kupezeka chifukwa cha kuchuluka kwa madzi.

4. Antistatic wothandizira

Ma polyethers ndi othandiza antistatic agents, ndipo L44 ikhoza kupereka chitetezo chokhalitsa cha electrostatic kwa ulusi wopangira.

5. Wobalalitsa

Ma polyeters amagwiritsidwa ntchito ngati dispersants mu zokutira za emulsion.F68 imagwiritsidwa ntchito ngati emulsifier mu vinyl acetate emulsion polymerization.L62 ndi L64 angagwiritsidwe ntchito ngati emulsifiers mankhwala, ozizira ndi mafuta mu kudula ndi kugaya zitsulo.Amagwiritsidwa ntchito ngati mafuta panthawi ya vulcanization ya rabara.

6. Demulsifier

Polyether ikhoza kugwiritsidwa ntchito ngati demulsifier yamafuta osakanizidwa, L64 ndi F68 imatha kuteteza mapangidwe amphamvu pamapaipi amafuta, ndipo angagwiritsidwe ntchito pobwezeretsanso mafuta achiwiri.

7. Zothandizira kupanga mapepala

Polyether ingagwiritsidwe ntchito ngati chothandizira kupanga mapepala, F68 imatha kusintha bwino pepala lokutidwa;imagwiritsidwanso ntchito ngati chothandizira kutsuka.

8. Kukonzekera ndi kugwiritsa ntchito

Polyether polyol mndandanda wa mankhwala makamaka ntchito yokonza okhwima polyurethane thovu, amene ankagwiritsa ntchito firiji, mufiriji, magalimoto firiji, mapanelo kutentha kutchinjiriza, kutchinjiriza mapaipi ndi madera ena.Zokonzedwazo zimakhala ndi matenthedwe otsika komanso okhazikika bwino, komanso ndizofunikira kwambiri pokonzekera polyether yophatikizana.Kupanga polyether polyols

M'makampani a polyurethane, amagwiritsidwa ntchito kwambiri popanga thovu la polyurethane, ndipo mitundu yayikulu ndi polyoxypropylene polyol ndi polytetrahydrofuran ether polyol.

Vinyl polima wolumikizidwa ndi polyether polyol amadziwika kuti "polymer polyol" (PolyetherPolyol), achidule kuti POP.Polymer polyol zachokera polyether polyol (zambiri zofewa thovu polyether triol, mkulu ntchito polyether), kuwonjezera acrylonitrile, styrene, methyl methacrylate, vinilu acetate, chlorine Ethylene ndi zina vinilu monomers ndi intiators amapangidwa ndi kwakukulu kumezanitsa polymerization pafupifupi 100 madigiri. ndi pansi pa chitetezo cha nayitrogeni.POP ndi polyether yodzaza ndi polyether polyol yomwe imagwiritsidwa ntchito popanga zinthu zonyamula katundu wambiri kapena modulus yapamwamba yosinthika komanso yolimba ya polyurethane thovu.Gawo kapena zonse za polyether yodzazidwa ndi organic imagwiritsidwa ntchito m'malo mwa polyether polyether-purpose polyols, yomwe imatha kupanga thovu yokhala ndi kachulukidwe kakang'ono komanso magwiridwe antchito apamwamba, omwe samangokwaniritsa zofunikira za kuuma, komanso kupulumutsa zopangira.Mawonekedwe nthawi zambiri amakhala oyera kapena achikasu achikasu, omwe amadziwikanso kuti polyether yoyera.

Chidziwitso: Nkhaniyi ikuchokera ku Lunan Polyurethane New Material pa WeChat 10/2021 Pokhapokha polankhulana ndi kuphunzira, musachite zinthu zina zamalonda, siziyimira malingaliro ndi malingaliro a kampani, ngati mukufuna kusindikizanso, chonde lemberani wolemba woyamba, ngati pali kuphwanya, chonde tiuzeni nthawi yomweyo kuti kuchotsa processing.
