Viscosifier yemvura yekuboorera (80A51)
Chigadzirwa ichi chine upfu huchena kana yero yakapfava husina kuyerera, ipolymer viscosity enhancer yakagadzirwa.
Chigadzirwa ichi chine simba guru rekudzivirira kunyorova uye munyu. Kana tembiricha yakakwira iri pamusoro pe120℃, viscosity inoshanda yemvura yekuboorera inogona kuwedzerwa kusvika pamusoro pe25mPa.s nekungowedzerwa ne0.3% chete, izvo zvinogona kuvandudza zvakanyanya kugona kwekutakura thixotropy uye chips yemvura yekuboorera. Panguva imwe chete, chigadzirwa ichi chinogonawo kushandiswa sechinhu chinoderedza kurasikirwa kwemvura.

Kurongedza nekutakura
Shandisa bhegi repurasitiki rakarukwa rine mapuranga maviri nemashanu kana mapepa epurasitiki akabatanidzwa. Rinogonawo kurongwa zvichienderana nezvinodiwa nemushandisi. Panguva yekuchengetera nekutakura, teerera kudzivirira kupisa nehunyoro, jira rekurongedza harifanirwe kudarika jira makumi maviri. Nguva yekuchengetedza inoshanda makore maviri.
Nyaya dzinoda kutariswa:
Dzivisa kusangana nemaziso, ganda nembatya, kana kusuka nemvura yakawanda. Chengeta kure nemoto.
1. Ndeapi marudzi emakemikari anoshandiswa zvakanyanya munzvimbo dzemafuta aripo?
Makemikoro akasiyana-siyana emumunda wemafuta anowanikwa kugadzirisa matambudziko chaiwo muindasitiri yemafuta negasi. Makemikoro anoshandiswa kazhinji anosanganisira mabhakitiriya, zvinodzivisa ngura, zvinobvisa munyu, zvinodzivisa kukweshana, zvinoderedza kukweshana, zvinogadzirisa manyuko emafuta, zvinogadzirisa mafuta uye zvinogadzirisa acid, nezvimwewo.
2. Ungatenga sei makemikari emumunda wemafuta?
Makemikoro emumunda wemafuta anogona kutengwa kuburikidza nevanotengesa makemikari vane marezenisi avo vanonyanya kugadzira zvigadzirwa zvakagadzirirwa kushandiswa kwemafuta negasi. Vatengesi ava vanowanzova nemapoka enyanzvi akazvipira anogona kupa mazano pakusarudza nekushandisa makemikari akakodzera zvichienderana nezvinodiwa chaizvo.
