Cov qauv ntawm pawg Y txawv, Cov Nplaim Retardant Agent yog tsim rau hom polymer kuj txawv li qub, qhov no yog vim hais tias pawg Y cov tshuaj tiv thaiv ntawm cov xim polymer, xws li muaj ethylene thiab methyl acryloyl pa raws li cov nplaim hluav taws, tshwj xeeb tshaj yog rau cov tsis tau tsim polyester cob thiab acrylic cob. Yog vim li cas rau qhov no yog tias nplaim Retardant Agent ntawm unsaturated ob leeg bonds nyob rau hauv unsaturated ob leeg nyiaj thiab resin nyob rau hauv qhov kev txiav txim ntawm initiator thiab accelerator, qhov tshwm sim ntawm kev fab tshuaj tshwm sim.
Tab sis muaj ob pawg ntawm Cov Nplaim Taws Cuam Tshuam siv nyob rau hauv epoxy rechin thiab phenolic ream, cov nyhuv tsis pom zoo, vim tias cov nplaim hluav taws ntawm cov nyiaj qiv tsis koom hauv kev kho cov tshuaj tua epoxy thiab phenolic ream. Tab sis epoxide pawg Flame Retardant Agent tshwj xeeb tshaj yog rau cov tshuaj epoxy, thiab vim epoxy pawg tuaj yeem nrog cov hydroxyl unsaturated polyester, yog li silane rau unsaturated polyester uas muaj epoxy pawg kuj thov tau; Thiab muaj cov kabmob Amelikas Retardant ntawm epoxy, phenolic, melamine resin, polyurethane txheej zoo.
- SH hauv nplaim hluav taws xob yog cov khoom siv roj hmab siv ntau yam.
Los ntawm cov lus saum toj ob, Nplaim Retardant Tus neeg saib xyuas los ntawm cov tshuaj bonds nrog rau kev txhim kho polymer thiab inorganic fillers hauv cov ntaub ntawv sib txuam, qhov adhesion ntawm qhov kev ua tau zoo heev, ces Tus Nplaim Retardant Agent kho tau li cas? Nws tuaj yeem ua tus xeeb ceem ntawm qhov theoretical binding force.
Raws li qhov kev xav ntawm adhesion ntawm interfacial Science News for KIDS, cov dispersion force yog mas pom nyob rau hauv theem nrab adhesion relay ntawm chav tsev ntawm cov nplaum thiab nplaum.
2. Cov nyhuv ntawm kev tshawb fawb thiab kev tshawb fawb fab nto
Nyob rau xyoo 1963, Lub Koom Txoos Hluav Taws Xob nyob rau hauv kev txheeb xyuas txog qhov kev nplaum ntawm qhov chaw sib txeeb thiab qhov hluav taws xob ntawm qhov paub txog ntawm cov ntsiab lus, tau tuaj rau qhov xaus uas nyob rau hauv cov khoom siv ntawm cov khoom sib xyaw, cov kua dej ua zoo infiltration ntawm glued khoom yog thawj tseem ceeb tshaj plaws, yog hais tias muaj peev xwm kis tau tag nrho infiltrates, lub cev adsorption nyob rau saum npoo ntawm lub zog ntawm high zog yuav muab siab tshaj cohesion lub zog ntawm cov organic cob hwj tsev ua zog lub zog.
