Kushanda

Maviri-echinhu chinonamira chinofanira kushandiswa mukati menguva inoshandisika mushure mekuisa muRE. Iyo yakareba yenguva inoshanda haizi chete ine chekuita neye polymer zvemukati zvekunamira, asi zvakare zvimwe zvinoenderana zvinhu (senge resini, antioxygen, plasticizer, solvent, nezvimwewo. Kana iri padyo nenguva inoshanda, kazhinji maawa mashoma kana rimwe zuva rekushanda, namira. inova yakaoma kushanda, uye viscosity inomuka munguva pfupi inotevera.Pakupedzisira, Inova jelly isingadzokere shure. , Yedu RE inoita 4-7.

Zvimwe Zvakatsanangurwa Zvakabatana

Kuchengetedza:

Ndapota chengetwa muhari yepakutanga yakavharidzirwa pasi pe23 ℃, zvigadzirwa zvinogona kuchengetedzwa zvakatsiga kwemwedzi gumi nemaviri. Iyo inonyanya kunetseka kune iyo mosture; ichave irikugadzira kabhoni dhayokisaidhi uye isingasviki urea mune inoitwa nemvura. Kana kuratidzwa kune teh mweya kana mwenje, kuchamhanyisa shanduko yemavara, asi basa rinoshanda harizokanganisike.
