Unoyeuka Meramine here? Ndiwo mhaka "mukaka poda inowedzera", asi zvinoshamisa kuti "zvinoshandurwa".

Musi waFebruary 2, bepa rekutsvagisa rakaburitswa mune zvakasikwa, rinotungamira resainzi resainzi, richiti Melamine rinogona kuitwa mune chimwe chinhu chakaoma kupfuura simbi uye chakareruka kupfuura mapurasitiki, zvakanyanya kushamisika kwevanhu. Pepa rakabudiswa neChikwata Inotungamirwa Nesainzi Masayenzi Michael Strano, purofesa muDhipatimendi remakemikari kuSyachusetts of Technology, uye Wokutanga munyori aive postdocderkidzana naYuwei zeng.

Vanzi vanonzi The The The The Thezvinhu mukatiVakatedzerwa kubva kuMylamine 2dpa-1, polymeni mbiri iyo yekuzvisimbisa mumashizha kuti aumbe zvishoma zvakashata, zvinhu zvepamusoro, izvo vatakuri vaviri vakamiswa.

Melelamine, inowanzozivikanwa seDimethylamine, is a White monclinsi crystal inotaridzika kufanana nemukaka P

Meleline haina kunaka uye zvishoma nezvishoma mumvura, asi zvakare muMethanol, formaldehyde, acetic acid, glyricerin, pyrican, pyrican, pyrican, pyrican, pyrican, pyrican, pyrican, pyridine, etc. Iko kusazvibata muacetone uye ether. Izvo zvinokuvadza kumuviri wemunhu, uye zvese zvakatsanangurwa kuti Melamine haafanire kuve akakosha pakudya kana zvekuvaka zvinhu, kunyanya pakudya, mahwendefa, mahwendefa uye zvimwe zvigadzirwa zvine zvakawanda zvekushandisa.

Iyo molecular formula ye melamine ndeye c3h6n6 uye iyo molecular uremu ndeye 126.12. Kuburikidza nemakemikari makemari emakemikari ane zvinhu zvitatu, kabhoni, hydrogen uye nitrogen zvimedu zvemumoyo, uye zvisungo zveHydrogen mumamoleky Mumamolekyuli anogadzika pamwechete, achigadzira chimiro che disc mukugara achigara, sechigadzirwa chemuganhuru, saka Melelensional Shepensional Shelamide yePolyamide mumaoko emasayendisiti.

Zvinyorwa zvakare zvinoshandiswawo nekugadzirwa, streno-

Vaongorori vakaona kuti zvinyorwa zvitsva zvine elasticity yekuwedzera, chiyero chesimba chinodikanwa kuti chigadziriswe, izvo ina kakapetwa katatu kupfuura iyo yebulllet progiramu. Ivo zvakare vakawana kuti kunyangwe paine wechitanhatu sechitanhatu sechidenga, polymer ine kaviri simba rakabiwa, kana simba rinodiwa kuti vatore zvinyorwa.

Imwe zvinhu zvakakosha zvezvinyorwa ndizvo zvechirwere. Nepo vamwe polymers vane makatuni akaremerwa nemapuru pane iyo gasi inogona kutiza, iyo zvinhu zvitsva zvine monomers iyo inosungira pamwe chete semabhandi uye mamorekuru haigoni kupinda pakati pavo.

Izvi zvinotibvumira kuti titore tete dzakatetepa-dzakatetepa dzinopindirana nemvura kana gasi rekupaza kwemvura, "

Iye zvino vatsvagiri vari kudzidza kuti iyi polymer ingaumbwa sei mumachira maviri-emapuranga mune zvimwe zvakadzama uye ari kuedza kuchinja midziyo yayo molecular yekugadzira mamwe marudzi ezvinyorwa zvitsva.

Izvo zvakajeka kuti izvi zvinyorwa zvinodikanwa kwazvo, uye kana zvichigona kugadzirwa, zvinogona kuunza shanduko huru kune emagetsi, nzvimbo yekudyara, uye minda yekudzivirira yebhora. Kunyanya mumunda wemotokari nyowani dzesimba, kunyangwe nyika zhinji dzichironga kuti dzizozeza mota dzemafuta mushure me20035, asi zvazvino simba idzva mota ichiri dambudziko. Kana izvi zvitsva zvinogona kushandiswa mumunda wemotokari, zvinoreva kuti uremu hwemotokari nyowani dzichaderedzwa zvakanyanya, asi zvakare kuderedza kurasikirwa kwesimba, izvo zvinoregera zvine simba mumotokari nyowani.
