Product Description

Peb RN, yog tsim los ua tus neeg saib xyuas / tus neeg sawv cev sib txuas rau cov nplaum raws li hydroxyl polyurethane, ntuj thiab hluavtaws roj hmab. RN yog aromatic NCO isocyanate, nws tsis muaj xim thiab tsis muaj kuab lom. Raws li RN nta zoo los tiv thaiv daj, nws yog tshwj xeeb tshaj yog haum rau lub teeb xim polyurethane nplaum thov. Vim tias cov kuab tshuaj yog ethyl acetate, RN tuaj yeem siv tau hauv cov tebchaws uas siv cov tshuaj methylene chloride txwv.

Khoom nta

Cov zaj duab xis ntawm cov nplaum thiab txheej zaj duab xis sib xyaw los ntawm RN yog los tiv thaiv daj tom qab raug UV teeb thiab / lossis cua sov. RN qhia tau hais tias kev sib raug zoo zoo hauv PVC nrog cov yas ntau dua, SBR nrog cov roj ntau dua, txheej tawv tawv, lo lo ntxhuav thiab lwm yam. RN tuaj yeem ua ke nrog polyester polyol thiab lwm yam hydroxyl-muaj cov khoom ua kom muaj ob lub ntsiab lus polyurethane kua roj vanish lossis xim xim. Nws muaj cov yam ntxwv ntawm kev ziab sai thiab tiv thaiv daj. Nws ceev pib curing thiab sanding zog yog nws qhov zoo tshaj plaws rau woodware.

Cov ntaub ntawv siv

RN yog ob lub ntsiab lus nplaum. Tom qab ntxiv ib qho kev faib ua feem ntawm RN rau cov nplaum, cov nplaum nplaum yuav tsum tau siv nyob rau hauv ib lub sij hawm (lub lauj kaub lub neej) uas txiav txim siab tsis tsuas yog los ntawm nws cov ntsiab lus ntawm roj hmab, tab sis kuj los ntawm lwm cov khoom xyaw. formulation (xws li resins, antioxidants, kuab tshuaj, thiab lwm yam). Yog tias cov nplaum tsis siv nyob rau lub sijhawm no, nws yuav nyuaj rau kev thov thiab nws cov viscosity nce sai heev kom txog rau thaum lub sijhawm gel tsis tuaj yeem tshwm sim thaum kawg. Yog li ntawd, nws tsis tau siv lawm.

Pom zoo Dosage:

Rau curing nplaum ntawm 100 qhov chaw los ntawm qhov hnyav (pbw) raws li:

Graft-Chloroprene roj hmab(cov ntsiab lus roj hmab kwv yees li 16%)	3-5% Pbw RN
chloroprene roj hmab(cov ntsiab lus roj hmab kwv yees li 20%)	5-7% Pbw RN
Hydroxyl polyurethane(polyurethane cov ntsiab lus kwv yees li 15%)	3-5% Pbw RN

Tag nrho peb cov khoom series yog rhiab heev rau cov dej noo; Nws yuav tsim carbon dioxide thiab insoluble urea nyob rau hauv cov tshuaj tiv thaiv nrog dej. Yog tias raug huab cua lossis / thiab lub teeb, nws yuav ua kom cov xim hloov ntawm cov khoom.

(Tab sis qhov kev ua tau zoo yuav raug cuam tshuam.)

Kev nyab xeeb:

Cov xwm txheej txaus ntshai, ua rau mob heev, ua rau lub qhov muag, yog tias nqus tau tuaj yeem ua rau muaj kev fab tshuaj. Kev kov tsis tu ncua tuaj yeem ua rau tawv nqaij qhuav lossis npau taws. Chav ntawm cov khoom tuaj yeem ua rau tus neeg qaug zog thiab vertigo.
