Peb lub RFE, yog ib qho tshuaj nplaum tawv uas muaj cov tshuaj thiophosphoric-tris-(p-isocyanato-phenyl ester) hauv ethyl acetate, CAS tus lej 4151-51-3. Cov xim kaj yog ib qho tshuaj kho kom zoo / crosslinker (isocyanate-hom) feem ntau siv rau cov nplaum rau cov roj hmab ntuj thiab / lossis cov roj hmab tsim, tshwj xeeb tshaj yog rau cov khoom siv roj hmab. Cov txiaj ntsig nrog nws cov xim kaj rau cov xim tsis muaj xim thiab tsis kam daj, RFE yog ib qho kev daws teeb meem zoo tshaj plaws rau kev thov xim nruj, zoo-haum rau cov nplaum grafted cr, chloroprene roj hmab nplaum thiab hydroxyl polyurethane nplaum. RFE kuj tseem tuaj yeem txhim kho kev sib txuas ntawm plasticizer PVC, oily SBR, txheej sab saud / primer tawv, silk thiab lwm yam. RFE kuj tseem tuaj yeem ntxiv rau hauv cov roj tawv nqaij kho tus neeg sawv cev kom tau txais kev sib txuas zoo dua thiab tiv thaiv roj. Cov kuab tshuaj ntawm RFE yog ethyl acetate (EAC), uas yog nyob rau hauv kab nrog kev tswj hwm ntawm kev tiv thaiv ib puag ncig piv rau methylene chloride. Ntxiv RFE rau hauv cov nplaum, nws ua rau muaj kev sib txuas thiab txuas cov substrates, tshwj xeeb tshaj yog rau cov khoom siv roj hmab.
Cov nplaum ob yam yuav tsum tau siv rau lub sijhawm uas siv tau tom qab muab tso rau hauv RFE. Lub sijhawm ntev ntawm lub sijhawm siv tau tsis yog tsuas yog cuam tshuam nrog cov polymer hauv cov nplaum xwb, tab sis kuj tseem muaj lwm yam khoom tseem ceeb (xws li reisn, antioxygen, plasticizer, solvent, thiab lwm yam). Thaum nyob ze rau lub sijhawm siv tau, feem ntau yog ob peb teev lossis ib hnub ua haujlwm, cov nplaum yuav nyuaj rau siv, thiab viscosity nce sai sai, Thaum kawg, nws dhau los ua cov kua nplaum uas tsis tuaj yeem rov qab tau.
RFE siv tau ua cov nplaum rau roj hmab thiab hlau, thiab ua tus neeg sawv cev kho kom sib txuas rau cov nplaum roj hmab thiab cov nplaum polyurethane uas muaj cov kuab tshuaj.
Feem ntau yog li ntawm 4% txog 7% ntawm cov nplaum uas siv cov kuab tshuaj uas tau hais los saum toj no. Nws yog siv tshwj xeeb rau kev sib txuas cov khoom tsis muaj xim lossis cov khoom xim dawb.
Daim ntawv thov suav nrog:
- Kev sib txuas rau roj hmab vulcanized (lossis unvulcanized) thiab PVC, PU, SBS thiab lwm yam polymers sib txuas ntawm cov ntaub ntawv thiab cov hlau (hlau / txhuas).
- Ua tus neeg sawv cev kho rau cov nplaum neoprene kom txhim kho lub zog sib txuas; tus neeg sawv cev kho rau roj hmab thiab ntaub sib txuas.
- Ua tus neeg sawv cev sib txuas rau cov khoom hydroxyl ntawm cov khoom polyurethane (elastomers, coatings, thiab lwm yam).
- Ua tus neeg sawv cev sib txuas rau cov nplaum hydroxyl-terminated polyurethane siv hauv kev lag luam khau, uas tuaj yeem txhim kho lub zog lo thawj zaug, tiv taus cua sov thiab lwm yam ntsuas.
- Feem ntau siv rau khau, hnab nqa khoom, hnab lag luam los txuas cov ntaub nrog PVC thiab / lossis PU.
Pom zoo kom noj ntau npaum li cas:
Nyob ntawm seb cov txheej txheem sib txuas thiab cov substrates ua haujlwm li cas, qhov ntau npaum li cas uas haum tshaj plaws yog pom zoo rau ntau yam kev xaiv.
Rau kev kho cov nplaum ntawm 100 qhov los ntawm qhov hnyav (pbw) raws li:
Roj hmab Graft-Chloroprene (cov roj hmab muaj li ntawm 16%): 3%-5% pbw RFE
Cov roj hmab Chloroprene (cov roj hmab muaj li ntawm 20%): 5%-7% pbw RFE
Hydroxyl polyurethane (polyurethane muaj li ntawm 15%): 3%-5% pbw RFE
Kev sib raug zoo nrog cov kuab tshuaj:
Peb cov RFE tuaj yeem diluted nrog anhydrous thiab tsis muaj cawv ethyl acetate dichloropropane, trichloroethylene, acetone, methyl ethyl ketone, toluene thiab lwm yam solvents. Ntxiv cov feem ntau ntawm aliphatic hydrocarbons tuaj yeem ua rau muaj turbidity. Txawm li cas los xij, cov tshuaj ntawm aliphatic hydrocarbons hauv roj hmab ntuj (NR) qhia tau tias zoo sib xws nrog RFE. Yog li, tsis tas yuav ntxiv lwm yam solvents.

Tag nrho peb cov khoom lag luam yog rhiab heev rau cov dej noo; Nws yuav tsim cov pa roj carbon dioxide thiab cov urea uas tsis yaj hauv cov tshuaj tiv thaiv nrog dej. Yog tias raug cua lossis/thiab lub teeb, nws yuav ua rau cov xim hloov pauv sai dua.
(Tab sis qhov kev ua haujlwm tiag tiag yuav raug cuam tshuam.)
Kev Nyab Xeeb:
Nws yog ib yam khoom txaus ntshai, yoo kub hnyiab, ua rau mob qhov muag, yog tias nqus tau ces yuav ua rau ua xua. Kev kov ntau zaus yuav ua rau daim tawv nqaij qhuav lossis vwm. Cov pa ntawm cov khoom no ua rau tus neeg qaug zog thiab kiv taub hau.
