Pamusoro pe:Iyo kambani inogona kutsvagisa nekugadzira zvigadzirwa zvitsva zvinoenderana nekwakakosha kudiwa kwevatengi vedu.
Features:RFE polyisocyanate inonyatso shanda crosslinker yekunamira yakavakirwa pa polyurethane,natural rabha uye Synthesis rabha. RFE polyisocyanate inobatsira zvakare mukuvandudza kunamatira kwerabha-yakavakirwa zvinhu. Inogona kushandiswa secrosslinker panzvimbo yeBayer's Desmodur RFE.
Kushandisa: Zviviri-zvikamu zvinonamira zvinofanirwa kushandiswa nenguva inoshanda mushure mekuisa muRFE. Hurefu hwenguva inoshanda haina hukama chete neiyo polymer yemukati yekunamira, asiwo zvimwe zvakakosha zvikamu (senge resin, Antioxygen, plasticizer, solvent, nezvimwewo). Kana iri pedyo nenguva inoshandiswa, kazhinji maawa mashomanana kana zuva rimwe rekushanda, kunamatira kunowedzera kuoma
shanda, uye viscosity inosimuka munguva pfupi. Pakupedzisira, inova jelly isingachinjiki. 100 yemhando yekunamira, Hydroxyl polyurethane ( Polyurethane account inotenderedza 20%), RFE inoita 4-7. Chloroprene rubber (Rubber account yeanenge 20%), RFE inoita 4-7.
Kuchengeta: Ndokumbira uchengetwe muchirongo chepakutanga chakavharwa pasi pe23℃, zvigadzirwa zvinogona kuchengetedzwa zvakagadzikana kwemwedzi mitanhatu. Zvese zvigadzirwa zveCrosslinker zvakateedzera zvakanyanya kunyorova; ichabudisa carbon dioxide uye insoluble urea mukuita nemvura. Kana kuratidzwa kumhepo kana mwenje, inomhanyisa shanduko yemavara ezvigadzirwa, Asi iyo inoshanda basa haikanganisike.
