Khoom Description
Polyether Glycol yog cov organic compound uas muaj ntau pawg hydroxyl. Nws tuaj yeem muaj lub ntsiab lus sib txawv me ntsis nyob ntawm seb nws puas tau siv hauv kev tshawb fawb txog zaub mov lossis cov tshuaj polymer. Polyols muaj ob, peb thiab
plaub pawg hydroxyl yog diol, triol, tetrol thiab lwm yam.
Tsawg molecular hnyav polyols yog dav siv nyob rau hauv polymer chemistry, qhov uas lawv ua hauj lwm raws li crosslinking agents. Alkyd resins rau
piv txwv yog siv nyob rau hauv cov xim thiab hauv pwm rau casting. Lawv yog cov tseem ceeb cob lossis "binder" hauv kev lag luam feem ntau "roj-raws li"
txheej txheej. Kwv yees li ntawm 200,{1}} tons ntawm alkyd resins raug tsim txhua xyoo. Lawv yog raws li kev sib txuas reactive monomers nrog
los ntawm kev tsim ester. Polyols siv hauv kev tsim cov khoom lag luam alkyd resins yog glycerol, trimethylolpropane.

Khoom siv: Polyether polyols
Polyether polyols 'kev siv loj yog nyob rau hauv polyurethane foams. Flexible foams feem ntau yog siv rau hauv cov ntaub ntawv cushioning xws li rooj tog zaum, txaj thiab rooj zaum hauv tsheb, thiab hauv cov ntaub pua plag hauv qab.
Rigid foam tus neeg siv khoom loj tshaj plaws yog kev tsim kho kev lag luam uas nws feem ntau yog siv rau rwb thaiv tsev.
Rigid ua npuas ncauj kuj yog siv rau hauv kev lag luam tub yees thiab ntim khoom. Kev siv me me rau polyether polyols suav nrog elastomers, adhesives thiab sealants, txheej txheej thiab polyurethane fibers.
