Melamine Molding Compound For Fridge Food Box
Iyo mbishi yekugadzira midziyo yakachenamelamine powder. Melamine molding compoundinogadzirwa ne melamine uye formaldehyde uye haina chepfu.Iyo inonzi thermosetting resin.Naizvozvo, melamine molding compound inogona kuumbwa kuita crockery at high temperature.Iri ndiro thermosetting compound rinopiwa mumarudzi akasiyana-siyana.Komboni iyi ine hunhu hwakatanhamara hwezvinhu zvakaumbwa, umo kupikisa makemikari uye kupisa kwakanakisa.Uyezve, kuoma, hutsanana uye kusimba kwepamusoro zvakare kwakanaka kwazvo.Inowanikwa mune yakachena melamine poda uye granular mafomu, uye zvakare yakasarudzika mavara e melamine poda inodiwa nevatengi.
Zvinhu Zvenyama:
Melamine inoumba musanganiswa muupfu fomu yakavakirwa pa melamine-formaldehyderesin yakasimbiswa ne-high-class celluloses yekusimbisa uye zvakare yakagadziridzwa neadiki madiki eakakosha ekuwedzera chinangwa, pigment, kurapa regulators uye mafuta ekuzora.
Zvakanakira:
1. Ruvara rwakanaka, ruvara rwakagadzikana uye kupenya, mavara akasiyana-siyana, sarudzo.
2. Easy fluidity uye yakaoma fluidity kusangana nezvinodiwa zvekuumba.
3. Good mechanical properties, kukanganisa kupikisa, kusina kusimba uye kupera kwakanaka.
4. High flame retardancy uye yakanaka kupisa uye kudzivirira mvura.
5. Isiri-chepfu, isina kunhuwa, inosangana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza zveEurope.
Applications:
1. Tableware: zvakaita sendiro, makapu, masoja, ladle, zvipunu, mbiya nemasosa, zvichingodaro.
2. Zvigadzirwa zvevaraidzo: senge dominoes, dice, mahjong, chess, nezvimwe.
3. Zvinodiwa zuva nezuva: senge ashtray, mabhatani, gaba remarara, chivharo chechigaro chechimbuzi.
Kuchengeta:
Kuchengeta pa25 centigrade kunopa kugadzikana kwemwedzi mitanhatu.Dzivisa hunyoro, tsvina, kukuvara kwekurongedza, uye tembiricha yakakwira iyo inokanganisa kuyerera kwechinhu uye kugona kwayo mold.
