Chii chinonzi gum?Ndizvo zvakafanana nepurasitiki here?

1. Chii chinonzi gum?

Gum, sezvinoreva zita racho, chinhu chinotorwa kubva mumiti, iyo inonyanya kutorwa kubva pakuvanzika kwemiti.Chinhu chacho chinonamira pachizvarirwo uye chinowanzoshandiswa sebhainda kana pendi.Muindasitiri yezvekudya, chingamu chinowanzo shandiswa kugadzira zvinonamira uye machira ezvekudya zvakaita sesiwiti, chokoreti uye chewing gum, izvo zvinogona kuwedzera kunaka uye kugadzikana kwechikafu.Panguva imwecheteyo, gum inoshandiswawo sezvishandiso uye machira mumishonga yemishonga, pamwe chete nemanamira uye machira mune zvakasiyana siyana zvekuvaka uye zvekushongedza zvinhu.

2. Plastiki chii?

Plastiki ndeye synthetic organic polymer zvinhu.Inogona kutorwa kubva kune zvicherwa zvakaita semafuta kana gasi rechisikigo kuburikidza neakasiyana makemikari maitiro.Plastiki ine purasitiki yakanakisa, kuchinjika uye hunhu hwekudzivirira, saka inoshandiswa zvakanyanya mukugadzira zvakasiyana siyana zvigadzirwa zvepurasitiki, senge mabhegi epurasitiki, pombi dzepurasitiki, mapepa epurasitiki zvichingodaro.

3. Chingamu chakafanana nepurasitiki here?

(1) Panyaya yekuumbwa uye zvisikwa, chingamu nepurasitiki zvinhu zvakasiyana zvachose.Gum ndeye yakasikwa organic polymer yakavanzwa nezvirimwa, uye plastiki ndeye organic polymer zvinhu zvakawanikwa neartificial synthesis.Maitiro avo emakemikari uye makemikari zvinhu zvakasiyana kwazvo.

(2) Panyaya yekushandiswa, chingamu nepurasitiki zvakare zvakasiyana kwazvo.Gum inonyanya kushandiswa mukunamira, machira uye maexcipients mune zvekudya, mushonga, zvekuvakisa uye zvekushongedza maindasitiri, nepo mapurasitiki achinyanya kushandiswa mukugadzira akasiyana epurasitiki zvigadzirwa, senge zvekurongedza zvinhu, zvekuvaka, zvigadzirwa zvemagetsi uye zvichingodaro.

Kazhinji, chingamu nepurasitiki zvinhu zviviri zvakasiyana zvachose, zvine misiyano yakakura mukuumbwa, zvivakwa, kushandiswa uye zvichingodaro.Naizvozvo, kana uchishandisa zvinhu zviviri izvi, zvinodikanwa kuti usarudze nzira yekushandisa yakakodzera uye zvinhu zvinoenderana nehunhu hwavo uye mashandisiro kuitira kudzivirira kuvhiringidzika uye kushandisa zvisizvo.
