Kowace rana mu yi amfani da kayayyakin sanya daga PVC. Menene wannan abu?

Ba dole ne a ce cewa rayuwa ta zamani zai zama sosai m ba tare da PVC. Mẽne ne a gare wani zamani tattalin arzikin? Details na PVC yau an up to 15 kilo na jimlar nauyin wani talakawan Turai mota, wannan abu ne da hannu a samar da mabukaci kaya (bukukuwa, tufafi, takalma, furniture, kasa marufai, katunan bashi, da dai sauransu)

Medicine ga fiye da rabin karni kuma yana amfani da PVC. Mẽne ne za a iya gani da nufin yawa guda-yin amfani da kayan aiki. Inda za ka iya samun kunshin ga Allunan, tayoyin, m safar hannu, catheters, na'urorin don ciyar, jini bags. Wannan abu ne halin da low cost, ya samu nasarar maye gurbin da roba da kuma gilashin, sauƙi haifuwa, shi za a iya amfani da a cikin jikin mutum.

Idan muka dubi abubuwan da suke a cikin gida, da yawa daga cikinsu suna kuma Ya sanya daga PVC. Abin da ake da shi na iya zama? Polyvinyl chloride ne sau da yawa da dalilin lantarki rufi, bututu, taga bayanan martaba, toys, marufi kayan, mobile phones, filastik kwalabe, shambura for man goge baki da yafi.

Abin da kayyade mai tartsatsi PVC? Mẽne ne tare da sinadaran ra'ayi? Bisa ga dabara (-CH2-CHCl-) a mataki n (digiri na polymerisation) PVC ne wani roba polymer wanda nasa ne da tushe da kuma aka samar daga chlorine da man fetur (57 kuma 43 bi da bi da cent). Production matakai a kasa da rabin da suka dogara a kan kayayyaki na man kayayyakin, abin da ya sa a saki wannan abu riba da kuma ta farashin - low.

Polyvinyl a bayyanar shi ne wani fari powdery abu da kyau dielectric Properties. Shi ne odorless kuma m, insoluble a ruwa, resistant zuwa hadawan abu da iskar shaka, talauci hasken (saboda chlorine a cikin abun da ke ciki), resistant zuwa acid, ma'adinai mai, alkalis, alcohols. Lokacin da ya kona zuwa 100 digiri C. abu decomposes hydrogen chloride 'yantar.

PVC yi farawa da hakar na sodium chloride gishiri bayani (da mataki na lantarki sallama). A a layi daya, da man cirewa daga ethylene (a hanya da ake kira "fatattaka"). Bayan nan, chlorine da ethylene hada amfanin ƙasa na ethylene dichloride. A nuna halitta dichloride, vinyl chloride (monomer), to, wanda aka tuba a Polymerization to da ake so abu. Don wannan suna kara daban-daban aka gyara, kyale su samu ƙãre samfurin tare da wasu kaddarorin ga dacewa kansu.

PVC masana'antun amfani uku na asali hanyoyin da Polymerization na monomers block, dakatar da emulsion. A wannan dakatar ana amfani da su samu taushi, Semi-m, kuma m robobi, da kuma emulsion - for m kayayyakin samu ta hanyar plastisols. Dangane da rashi ko gaban plasticizers a cikin abun da ke ciki an saki, bi da bi unplasticized da plasticized abu. Na farko shi ne kasa resistant to low yanayin zafi (har zuwa debe 15 digiri C), da kuma na biyu tsayayya sanyaya zuwa -60 digiri. Yau, mafi latsa matsala da wadannan abubuwa ne da tarin da kuma sake amfani.
