Njira yolongedza: mapepala / thumba lapulasitiki lophatikizika / thumba lachidebe
Zoipitsa m'madzi (Inde/Ayi) : Inde.
Njira zodzitetezera: Izi ndi zamadzimadzi, ndizoletsedwa kusakaniza ndi okosijeni, mankhwala odyeka, alkali, asidi anhydride, ndi zina zotero. Poyendetsa, ziyenera kutetezedwa ku dzuwa, mvula ndi kutentha kwakukulu.Chilimwe momwe ndingathere m'mawa ndi madzulo zoyendera, kuteteza kuwala kwa dzuwa, zoyendera malinga ndi mzere wotchulidwa, kuyimitsidwa kuyenera kukhala kutali ndi moto, magwero a kutentha, malo otentha kwambiri.Ndizoletsedwa kunyamula katundu m'galimoto imodzi monga mankhwala odyedwa.Poyendetsa pamsewu, iyenera kutsatira njira yovomerezeka ndipo isakhale m'madera okhala ndi anthu ambiri.Ndi zoletsedwa kuwazembera m'mayendedwe a njanji.Sitima zamatabwa zamatabwa ndi zombo za simenti ndizoletsedwa kwambiri mayendedwe ochuluka.
P-tert-butylphenol ali ndi antioxidant katundu ndipo angagwiritsidwe ntchito ngati stabilizer kwa labala, sopo, chlorinated hydrocarbons ndi ulusi kugaya chakudya.Uv absorbent, mankhwala, mphira, utoto ndi anti cracking agent.Mwachitsanzo, amagwiritsidwa ntchito popanga utomoni wa polycarbon, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, styrene stabilizer.Kuphatikiza apo, ndizinthu zopangira mankhwala othamangitsa tizilombo, mankhwala ophera tizilombo ndi ma acaricide, fungo labwino komanso chitetezo cha zomera.Itha kugwiritsidwanso ntchito monga zofewa, zosungunulira, zowonjezera utoto ndi utoto, antioxidant wamafuta opaka mafuta, demulsifier yamafuta ndi zowonjezera zamafuta agalimoto.
Mapulogalamu ena:
(1) Kwa mafuta osungunuka a phenolic resin, mankhwala ndi formaldehyde condensation amatha kupezeka pazifukwa zosiyanasiyana.Mu zomatira chloroprene osakaniza 10-15% ya mankhwala, kupeza sungunuka utomoni, zomatira mtundu uwu makamaka ntchito zoyendera, zomangamanga, boma, kupanga nsapato, etc. kusindikiza, photogravure zapamwamba ndi zina zotero.Mu kutchinjiriza varnish, angagwiritsidwe ntchito koyilo kuviika varnish ndi laminate varnish.
(2) Pakuti polycarbonate kupanga, monga phosgene polycarbonate anachita kuthetsa wothandizila, kuwonjezera Chemicalbook kuchuluka kwa 1-3% ya utomoni.
(3) Amagwiritsidwa ntchito pa epoxy resin, xylene resin resin;Monga polyvinyl chloride stabilizer, surfactant, UV absorber.
(4) Ndi katundu antioxidant, angagwiritsidwe ntchito ngati mphira, sopo, chlorinated hydrocarbons ndi nitrocelluloose stabilizer.Ndiwopangira mankhwala othamangitsa tizilombo (mankhwala), acaricide acaride (mankhwala ophera tizilombo) ndi woteteza mbewu, kununkhira, utomoni wopangira, komanso angagwiritsidwe ntchito ngati zofewa, zosungunulira, utoto ndi zowonjezera utoto.Itha kugwiritsidwanso ntchito ngati chophatikizira cha demulsifier pamunda wamafuta komanso chowonjezera chamafuta amgalimoto.
