Umsebenzi nokusetshenziswa kwe-polyvinyl alcohol

I-Polyvinyl alcohol isetshenziswa izikhathi eziningi empilweni yethu.Kunezigaba eziningi ze-polyvinyl alcohol kanye nokusetshenziswa okuningi kwe-polyvinyl alcohol.Idlala indima ebaluleke kakhulu ekukhiqizeni nasekuphileni kwethu.Abanye abantu abacaci kahle mayelana nokusetshenziswa kwe-polyvinyl alcohol, ngakho-ke, yini ukusetshenziswa kwe-polyvinyl alcohol?Ake sibheke!
Iyini i-polyvinyl alcohol?
I-Polyvinyl alcohol iyinhlanganisela yemvelo, ifomula yamakhemikhali [C2H4O] N, ukubukeka kungama-flake amhlophe, oku-flocculent noma okuyimpushana okuqinile, akunambitheki.Incibilika emanzini (ngaphezu kuka-95℃), incibilika kancane ku-dimethyl sulfoxide, ayincibiliki kuphethiloli, uphalafini, uwoyela wemifino, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, njll.
Okwesibili, indima ye-polyvinyl alcohol.
Isetshenziselwa ukwakhiwa kwe-polyvinyl acetal, ipayipi elingazweli uphethiloli kanye ne-vinylon, i-ejenti yokwelapha indwangu, i-emulsifier, i-paper coating, i-adhesive, njll.
Ukuhlukaniswa kwamakhemikhali asetshenziswayo
Izinto zokusetshenziswa zamakhemikhali zingahlukaniswa zibe izinto ezingavuthiwe zamakhemikhali ezingaphili.
Ukuhlukaniswa kwezinto ezisetshenziswayo zamakhemikhali aphilayo
Ingahlukaniswa ngama-alkanes kanye nokuphuma kwawo, ama-alkenes kanye nokuphuma kwawo, ama-alkynes kanye nokuphuma kwawo, ama-quinone, ama-aldehydes, ama-alcohol, ama-ketone, ama-phenols, ama-ethers, ama-anhydrides, ama-esters, ama-organic acid, i-carboxylate, ama-carbohydrate, i-heterocyclic, i-nitriles, i-halogena, kanye nezinye izigaba.
Ukwahlukaniswa kwezinto zamakhemikhali ezingaphili
Izinto zokusetshenziswa eziyinhloko zemikhiqizo yamakhemikhali angaphili isibabule, i-sodium, i-phosphorus, i-potassium, i-calcium namanye amaminerali amakhemikhali (bheka imboni kasawoti ye-inorganic) namalahle, uwoyela, igesi yemvelo nomoya, amanzi nokunye.
Yiziphi izinto ezisetshenziswa ngamakhemikhali e-organic
Imboni yamakhemikhali e-organic isifinyezo semboni yamakhemikhali e-organic, eyaziwa nangokuthi imboni ye-organic synthesis.Ngokusekelwe ku-petroleum, igesi yemvelo, amalahle nezinye izinto zokusetshenziswa, ukukhiqizwa okuyinhloko kwezimboni ezihlukahlukene zezinto zokusetshenziswa eziphilayo.Izinto ezisetshenziswayo eziqondile zamakhemikhali emvelo zihlanganisa i-hydrogen, i-carbon monoxide, i-methane, i-ethylene, i-acetylene, i-propylene, i-carbon four noma ngaphezulu i-aliphatic hydrocarbons, i-benzene, i-toluene, i-xylene, i-ethylbenzene nokunye.Kusuka kuwoyela ongahluziwe, i-petroleum distillate noma igesi ephansi ye-alkane eqhekeka igesi, igesi yokucwenga kanye negesi, ngemuva kokwelashwa kokuhlukaniswa, kungenziwa ngezinhloso ezahlukahlukene zezinto zokusetshenziswa kwe-aliphatic hydrocarbon;I-aromatics ingahlukaniswa kuphethiloli oshintshiwe wokuguqula izinto, uphethiloli oqhekekile wokuqhekeka kwe-hydrocarbon kanye netiyela lamalahle lokuphindaphinda kwamalahle.
