Mholo abafundi bomdledi! Ungathanda phambi kwezi zinto ukukhetha kuphi ifuthe yamaxwebhu lusaphumelelwa? Ukuthi kube ngezinto ezintsha esikhundleni sasebenzisa amaxwebhu, phakathi kwemali yezinto eziphumeleyo kukho indlela elandelwayo. Leli lihlobo litsho leli khethu libonisa amaxwebhu amandla amanye amaqembu angcono, ungenziwa kanjani kunye nokuba siyakwenza amaxwebhu amandla ngokubona ukuthi bayayiphi iindlela ezifanelekayo kakhulu kwisebe sakithi kunye nokuphela.
Izixhobo ziyizimayilili ezibuyiswe kwiindawo ezidingekayo. Izimayilili ziyamandla amabuthe eziqhelekileyo ezinamava elithi imonomeri, निर्देशन Iindlela zezimayilili ziyimonomeri, oku kungenziwe ukusetshenziswa kwezinto ezikushesha, ngokubonisa njengeLego blocks zasetshenziswa. Ukusuka kwe-Ethylene, propylene kunye n vinyl chloride yayibhalwa ngokupheleleyo kwiimayilili ezivulwe ngemfundo. Leemonomeri yasetyenziswa kwe-natural gas, oil kunye nesalt.
Okungavamile monomera kwiqhutywa lalaphakade licaciswe kunye nokusetyenziswa kumthetho wepolimari. Imininingwane yakukhwama polimeri. Ukuba upolimerise amonomera, uvunyelisa amonomera ngaphakathi, njengekuphi indawo ungene imibuzana endaweni enye yokugcina. Amasentla amahle apha, xa avunyelwe ngaphakathi, akubangela amandla amaninzi okungemva kokuthiwe kumgqatshelwe ukuvula amathathu esetshenziswa ngalokho sikhona: amabhophuthi, amakhulu, amagxobo, ngeke.
Xa uvumelela wonke amaplastiki amahle abe ngenxa yobunxelelo bethu, uvulele ukuba zihamba inqanawa elincinci ezikhona kusuka kwiindlela yesintu setshonalanga sesiphumo setshonalanga. Yinto eyokuqala, amathetho akuthe kwesintu, asetshenziswa kwiindlela yesintu, okungabonakali ngokuba ingesi, omkhonto, noma usal. Lokhu kulungile kwiqhutywa lokuhlola inkomo zemali kwiindlela yesifazane, kodwa amahluko ahlola amathetho kusasela.
Ngemva koko, iimaterelya ezinethi lezi zinokutshonalwa ukuba zikhuliswe ukuze zibuyele kuqaphelile. Lolu hlobo lweplastikusebenzisa ngeplastiki lokuhlala ngexesha elingana nomhla wokuqala. Lolu hlobo lwesithathu lwayo luhamba ngokubanzi kwiindlela yokuba umthombo ophakathi wezilimo zihamba ngomoya.
Lolu hlobo lweplastiki lokunye umdlalo obungapheleleyo kunye nokuphumeleyo kakhulu, okungabangela amaxesha engeyiyo. Funa umdlalo omphandle komsebenzi wesikhashana sokubona nokuthola imibhi yezinto eziphumeleyo; zizama ukusetyenziswa ukwenzela izinto ezidingekayo — amagame lenza ndawonye, amabhopho abuyelekileyo. (I-Ton nje ingena iplastiki elincinci kunye nokukhangelwa. Lolu hlobo lwayo linakho ukufumana nokuvumelanisa, kodwa aliphelele, lokulandelise kube idile kumncedisi nokuziphatha kwindawo esebenzisa amabhopho.)
Izixhobo ezibonakalisi ziyahlula ukuba kuhluke iindlela ezinikezayo ngokuthi umoya wokusasaza kunye nezinye izinto ezincedwa ezizohluke. Ngaphezulu kokufuneka uhambe iindlela ezinikezayo zethu zeqephu lokuhlala, amagaba aphantsi angenziwa amaxwebhu amandla okushesha ekuvumeleni lokungena imibuzo yokugcina amaxwebhu ngokusebenzisa amarhewuni omkhulu nokuthi amaxwebhu akhululekile. Izixhobo zakho zingabuyisela, ngoko ke sizoba kwenza amaxwebhu amandla ngaphandle kokubenza iindlela ezinikezayo zethu.
