Composite-initiated Tshwj xeeb Polyether Polyols

Polyether polyols nrog cov neeg pib sib xyaw xa mus rau polyether polyols uas muaj ob lossis ntau tus neeg pib. Cov neeg pib no feem ntau suav nrog glycerol (propylene glycol), sorbitol, sucrose, thiab lwm yam, uas cuam tshuam nrog ethylene oxide (EO), propylene oxide (PO), thiab lwm yam nyob rau hauv muaj cov catalyst los tsim polyether polyols.

Composite-initiated polyether polyols yog ib hom tshwj xeeb ntawm polyether polyol uas tau npaj siv cov khoom pib sib xyaw, lawv yog cov ntaub ntawv tseem ceeb uas siv dav hauv cov khoom siv polyurethane. Composite pib polyether polyol yog tsim los ntawm cov tshuaj tiv thaiv ntawm polyether tebchaw nrog polyols, ua rau siab molecular hnyav tebchaw nrog ntau pawg hydroxyl functional.

Polyether polyols ua raws li plasticizers hauv polyurethane ntau lawm, tso cai rau kev hloov kho ntawm nws cov khoom thiab cov yam ntxwv.

Reactivity: Lub reactivity ntawm polyether polyol nrog composite pib yog nyob ntawm tus naj npawb ntawm cov nquag hydrogens nyob rau hauv lub initiator. Feem ntau hais lus, thaum qhov hnyav molecular tsis txawv ntau, rau tib yam PO hom polyether, polyether nrog ethylenediamine thiab aniline raws li cov neeg pib muaj kev ua haujlwm siab tshaj plaws, thiab polyether nrog pentaerythritol thiab sucrose polyols raws li cov thawj coj kuj tseem siab, thaum lub polyether nrog ethylene glycol thiab propylene glycol raws li cov neeg pib ua haujlwm qis dua.

viscosity thiab hydroxyl tus nqi: Rau tib hom polyether, qhov siab dua hydroxyl tus nqi, qhov me me qhov hnyav molecular, siab dua qhov reactivity, thiab qis dua qhov viscosity. EO-terminated polyethers feem ntau yog nquag nquag thiab ntau hydrophilic tshaj li tag nrho-PO polyethers. Qhov siab dua cov ntsiab lus EO, qhov pom tseeb dua qhov qauv no.

Composite-initiatiated polyether polyols yog siv nyob rau hauv ob qho tib si mos ua npuas ncauj thiab tawv ua npuas ncauj polyethers. Mos ua npuas ncauj polyethers yog tsuas yog siv nyob rau hauv lub polyurethane mos ua npuas ncauj kev lag luam thiab zus tau tej cov polyurethane adhesives, thaum nyuaj ua npuas ncauj polyethers yog dav siv nyob rau hauv lub tshav pob ntawm cov khoom siv hauv tsev rwb thaiv tsev, lub tsev sab nrauv phab ntsa rwb thaiv tsev, thiab lwm yam.

Ua npuas ncauj yas: Polyether polyols yog ib qho ntawm cov khoom siv tseem ceeb rau kev tsim cov polyurethane ua npuas ncauj yas. Nws tuaj yeem siv los tsim cov khoom muag muag thiab tawv polyurethane ua npuas ncauj, uas yog siv dav hauv rooj tog, tsheb, kev tsim kho thiab lwm yam. Adhesives thiab elastomers: Polyether polyols kuj siv los ua cov nplaum thiab elastomers. Cov khoom no muaj cov khoom sib txuas zoo thiab elasticity thiab tsim nyog rau ntau yam kev sib txuas thiab kev sib khi. cov

Coatings : Hauv kev lag luam coatings, polyether polyols feem ntau yog siv los npaj cov txheej txheem ua haujlwm siab, muab cov txheej txheem zoo heev thiab ua haujlwm ntev. cov

Lwm yam kev siv: Tsis tas li ntawd, polyether polyols kuj tseem siv los tsim ua npuas ncauj stabilizers, defoamers rau kev lag luam ntawv, roj demulsifiers, high-efficiency low-foam detergents, lubricants, quenching agents, latex foaming agents, rubber lubricants and surfactants, etc. .

Tsis txhob cia cov khoom sib xyaw ua ke ntawm polyether polyol tiv tauj nrog daim tawv nqaij lossis ob lub qhov muag.
Tsis txhob ua pa hauv vapors lossis pos huab.
Khaws cov polyol kom deb ntawm hluav taws los yog sparks thiab tsis haus luam yeeb
Ua tib zoo saib xyuas kom tsis txhob muaj qhov sib txuam ntawm cov hluav taws xob zoo li qub.

Thaum lub sij hawm cia thiab kev thauj mus los, cov khoom sib xyaw-pib tshwj xeeb polyether polyols,
xav tau ntim rau hauv galvanized steel nruas, kom txias thiab qhuav, tsis muaj dej, tsis muaj cua sov

Tsuas yog cov khoom sib xyaw-pib tshwj xeeb polyether polyols, peb kuj muaj

Sucrose pib polyether polyols

Sorbitol pib polyether polyols

EDA pib tsim cov polyether polyols
