Umsebenzi kunye nokusetyenziswa kotywala bepolyvinyl

Utywala bePolyvinyl busetyenziswa ngamaxesha amaninzi ebomini bethu.Kukho iindidi ezininzi zotywala bepolyvinyl kunye nokusetyenziswa okuninzi kotywala bepolyvinyl.Idlala indima ebaluleke kakhulu kwimveliso kunye nobomi bethu.Abanye abantu abacaci kakuhle malunga nokusetyenziswa kotywala be-polyvinyl, ngoko ke, yintoni ukusetyenziswa kwe-polyvinyl alcohol?Makhe sijonge!
Yintoni utywala polyvinyl?
I-Polyvinyl alcohol yi-organic compound, formula yekhemikhali [C2H4O] N, inkangeleko yiflake emhlophe, i-flocculent okanye umgubo oqinileyo, ongenancasa.Inyibilika emanzini (ngaphezu kwe-95℃), i-soluble kancinane kwi-dimethyl sulfoxide, ayinyibiliki kwi-petroli, kwi-kerosene, i-oli yemifuno, i-benzene, i-toluene, i-dichloroethane, i-carbon tetrachloride, i-acetone, i-ethyl acetate, i-methanol, i-ethylene glycol, njl.
Isibini, indima yepolyvinyl utywala.
Isetyenziselwa ukwenza i-polyvinyl acetal, umbhobho onganyangekiyo wepetroli kunye ne-vinylon, iarhente yokunyanga ilaphu, i-emulsifier, i-coating yephepha, i-adhesive, njl.
Ukuhlelwa kwezinto zemichiza ekrwada
Imathiriyeli ekrwada yeekhemikhali inokohlulwa ibe yimathiriyeli ekrwada ye-organic kunye ne-inorganic chemical ekrwada.
Ukuhlelwa kwemathiriyeli ekrwada yeekhemikhali
Inokwahlulwa ibe yi-alkanes kunye ne-derivatives yazo, i-alkenes kunye ne-derivatives, i-alkynes kunye ne-derivatives, i-quinones, i-aldehydes, i-alcohol, i-ketones, i-phenols, i-ethers, i-anhydrides, i-esters, i-organic acids, i-carboxylate, i-carbohydrates, i-heterocyclic, i-nitriles, i-halogenaids, kunye nezinye iindidi.
Ukuhlelwa kwemathiriyeli ye-inorganic chemical ekrwada
Izinto eziphambili zeemveliso zeekhemikhali ze-inorganic ziyi-sulfure, i-sodium, i-phosphorus, i-potassium, i-calcium kunye nezinye iiminerali zemichiza (jonga imboni yetyuwa ye-inorganic) kunye namalahle, i-oyile, igesi yendalo kunye nomoya, amanzi njalo njalo.
Zeziphi izinto zemichiza ephilayo ekrwada
Ishishini lemichiza ye-Organic sisishunqulelo seshishini lemichiza ephilayo, eyaziwa ngokuba yi-organic synthesis industry.Ngokusekwe kwipetroleum, igesi yendalo, amalahle kunye nezinye izinto ekrwada, eyona mveliso iphambili yoshishino lwezinto eziphilayo ekrwada.Izinto ezisisiseko ze-organic organic ekrwada ekrwada ziquka i-hydrogen, i-carbon monoxide, i-methane, i-ethylene, i-acetylene, i-propylene, i-carbon four okanye ngaphezulu i-aliphatic hydrocarbons, i-benzene, i-toluene, i-xylene, i-ethylbenzene njalo njalo.Ukusuka kwi-oyile ekrwada, i-petroleum distillate okanye i-alkane ephantsi yokuqhekeka kwegesi, igesi yokucoca kunye negesi, emva konyango lokwahlula, inokwenziwa ngeenjongo ezahlukeneyo ze-aliphatic hydrocarbon ekrwada;I-aromatics inokohlulwa kwipetroli ehlaziyiweyo ye-catalytic reforming, i-petroli eqhekekileyo yokuqhekeka kwe-hydrocarbon kunye netha yamalahle yokuphindaphinda kwamalahle.
