Pamusoro pe:Iyo kambani yaigona kutsvagurudza uye kukudziridza zvigadzirwa zvitsva zvinoenderana nekudikanwa kwevatengi vedu.
Zvimiro:RFE Polyisocyanate inyanzvi inobudirira kwazvo yemakwenzi yakavakirwa pane polyurethane, yakasikwa rabara uye synthesis rabara. RFE Polyisocyanate zvakare inobatsirawo mukuvandudza kunamatira kwezvinhu-zvakavakirwa zvinyorwa. Inogona kushandiswa seanoyambuka pane bayer's destomitur rfe.
Kushandiswa: Maviri-chikamu chinonamatira chinofanira kushandiswa nenguva inoshanda mushure mekuisa rfe. Kureba kwenguva inoshanda hakuna kuwirirana nemutengo wemanyorerwo ezvinonamatira, asi zvimwewo zvikamu zvakakodzera (saResin, Antioxygen, Plticsezer, solvent, etc). Kana iri pedyo nenguva inoshanda, kazhinji maawa mashoma kana rimwe zuva rekushanda, kunamatira kunova kwakaoma kuoma
Shanda, uye viscosity inosimuka munguva pfupi. Pakupedzisira, inova isingachinjiki jelly. 100 mhando inonamatira, hydroxyl polyurethane (polyurethane account yekutenderedza 20%), RFE anoita 4-7. Chloroprene Rubber (Rubber Akaunti yeKutenderedza 20%), RFE anoita 4-7.
Kuchengetedza: Ndokumbirawo kuchengetedzere muchipatara chisimbiso chepakutanga pasi pe23℃, zvigadzirwa izvo zvinogona kuchengetedzwa chakagadzikana kwemwedzi mitanhatu. Zvese zvevakadyidzana zvinoteedzana zvigadzirwa zvinotaridzika chaizvo nekunyorova; Iyo ichagadzira carbon dioxide uye insoluble urea mukuita nemvura. Kana kuratidzwa kwemhepo kana mwenje, inokurumidzira shanduko yezvigadzirwa, asi basa rinoshanda harina kukanganiswa.
