Melamine resin ipolymer inowanikwa nekuita kwe melamine uye formaldehyde.Iyo inozivikanwawo se melamine formaldehyde resin.Chidimburidzo cheChirungu ndicho MF.
Zvigadzirwa zvayo infusible thermosetting resins.Inowanzo kunzi amino resin pamwe neurea-formaldehyde resin.
1. Melamine resin inogadzirwa muzvigadzirwa zvakaumbwa zvine mavara akapfuma, anonyanya kushandiswa mukugadzirwa kwemapuranga ekushongedza, tableware, zvinodiwa zvezuva nezuva, nezvimwewo. The tableware inoita seporcelain, haisi nyore kuva brittle uye yakakodzera kushambidza dishwasher.
2. Melamine resin uye urea-formaldehyde resin inogona kusanganiswa mumatanda, ayo anoshandiswa kugadzira laminates.
Kunyange zvazvo melamine resin inodhura kupfuura urea resin, chetemelamine resin (upfu fomu)inogona kuumbwa kuita chikafu rade gmelamine tableware.Huafu Chemicals inyanzvi mukugadzirwa kwe100% kuchena melamine formaldehyde molding compound.Kugamuchirwa kushanyira fekitari yedu muChina.
Urea-formaldehyde resin is urea uye formaldehyde pasi pechiito checatalyst, polycondensation mune yekutanga urea-formaldehyde resin, uyezve pasi pechiito cheanorapa ajenti kana anobatsira mumiriri kuumba isinganyungudike uye infusible yekupedzisira thermosetting resin.Iyo inozivikanwawo se urea formaldehyde resin.Chidimburidzo cheChirungu chinonzi UF.
1. Iyo yakarapwa urea-formaldehyde resin yakareruka muruvara, inopenya, inoshingirira kune isina kusimba asidhi uye isina kusimba alkali, yakanaka insulation performance, yakanakisa abrasion resistance, uye mutengo wakaderera.Inoshandiswa zvakanyanya mukunamira.
2. Urea-formaldehyde iri nyore kuora kana iine asidhi yakasimba uye alkali yakasimba, uye ine mamiriro ekunze asina kunaka, shrinkage yakakura, brittleness yakakwirira, kusashivirira kwemvura, uye kukwegura nyore.Wood-based panels inogadzirwa neurea-formaldehyde resin ine dambudziko rekuburitswa kwe formaldehyde panguva yekugadzira nekushandisa maitiro, saka inofanirwa Kuishandura.
