Namuhla, inkinga yepulasitiki ibucayi emhlabeni wonke. Ngomjikelezo wokuqoqeka we-biosphere, ipulasitiki eyenziwe ngabantu izobuyela kubantu. Ngakho-ke yiziphi izinto ezingashintsha ngempumelelo oplastiki? Le eyehliswa kalula kalula futhi kulula kakhulu ukuyiphatha. Angikhulumi ngendwangu ejwayelekile nezinye izinto.



Okwamanje ayikho.

1. Ama-plastiki akhona njengamanje abhekwa njengomkhonyovu:

Ezinye zifaka izithako ezifana ne-starch ne-calcium carbonate ku-polyethylene yendabuko ukunciphisa inani le-polyethylene. Lokhu konakaliswa kuyimbumbulu ngokuphelele.

Ipulasitiki leqiniso elonakele elimelwe yi-polylactic acid lingehlisa ngaphansi kuka-5% ngaphansi kwezimo zemvelo zokulahla udoti. Ukwehliselwa phansi kudinga i-acid hydrolysis enamandla noma ukuvutshelwa okushisa okuphezulu. Ngaphezu kwalokho, impahla eluhlaza ye-polylactic acid ingukudla, futhi ukukhiqizwa kwepulasitiki ekudleni uqobo kuyimfucuza enkulu. Intengo ye-polylactic acid nayo ibiza ngokweqile ngokuqhathaniswa namapulasitiki wendabuko.

Umnyombo wokungcola kwepulasitiki ukuthi yonke imikhiqizo yepulasitiki ingabuyiselwa ohlelweni lokulahlwa kukadoti ukuze lushiswe noma lushaywe kabusha noma lusetshenziswe kabusha. Akusho lutho ukuthi imikhiqizo yepulasitiki yasemadolobheni yehliswe, futhi iningi lemikhiqizo epulasitiki yasemadolobheni ingabuyiselwa ohlelweni lokulahla udoti. Amafilimu e-mulch yezolimo (avame ukuguga futhi aphulwe ezweni iminyaka emi-2 ngaphambi kokuba alahlwe) nezinhlayiya zepulasitiki zokuhlanza yizona izimbangela ezinkulu zokungcola kwepulasitiki. Angifuni ukuxazulula inkinga enkulu yokuphikisana okuyinhloko, kepha bukela ukungqubuzana kwesibili bese ushaya ibhodi. Lokhu kuyefana neqembu leBai Zuo elishayela i-jet yacht yangasese enemoto enkulu yokuhamba kwiNgqungquthela Yokuvikelwa Kwezemvelo.

Ukucekelwa phansi komhlaba ngokwawo akuyona indlela enengqondo yokulahla amapulasitiki. Ukulahlwa okufanele kwepulasitiki ukuxazulula inkinga yokushiswa okungenangozi uma kuhlangana kahle. Njengoba nje ukuxoxa ngokuwohloka kwe-cermet, koqweqwe lwawo, ingilazi nemikhiqizo yamatshe kuyahlekisa ngokuphelele.

2. Njengempahla esetshenziswa kakhulu, intengo / isisindo / ukuhlukaniswa kokusebenza kwepulasitiki kuswele abangafaka esikhundleni.

Izindwangu zemvelo zibiza kakhulu futhi kusadingeka ukuthi zifakwe opulasitiki noma upende ukuze kuzuzwe ukufakwa kwezinga lepulasitiki.

Ukufakwa kwephepha kubi kakhulu. Iningi lephepha lokuxhumana lokudla elisetshenziswa embonini yokudla ligcwele upulasitiki noma i-wax. Njengoba yonke imikhiqizo yepulasitiki isetshenziswa, kungani ungasebenzisi yonke imikhiqizo epulasitiki? Ukungcoliswa kokukhiqizwa kwamaphepha akukuphansi.

Insimbi, i-ceramic, i-koqweqwe lwawo, ingilazi namatshe kusinda kakhulu uma kuqhathaniswa nepulasitiki. Ukufakwa komkhiqizo woqalo nokhuni akwamukelekile neze, futhi ukumuncwa kwemikhiqizo ephansi yoqalo nemithi yezinkuni kunamandla kakhulu ukuhlangabezana nezidingo. Intengo yoqalo oluminyene nemikhiqizo yezinkuni ene-adsorption ebuthakathaka inyukile.

Inkinga eyodwa ngenjoloba, irabha le-silicone nepulasitiki.

3. Izinto zokwakha zingahlukaniswa ngokulinganayo ngezigaba ezilandelayo: izinto zensimbi (izinsimbi eziyinsimbi, izinsimbi ezingezona ezensimbi, izinsimbi eziyigugu), izinto ezingezona ezensimbi ezingaphili (usimende, ingilazi, izinto zobumba), izinto zepolymer (amapulasitiki, injoloba, imicu) kanye izinto eziyinhlanganisela. Izinto ezintathu eziyisisekelo: insimbi, izinto ezingaphili kanye ne-polymer. Izinzuzo zama-polymers isisindo esincane, amandla aphakeme, ukucubungula okulula, kanye nokwenza izinto obala. Yikuphi okubalulekile ocabanga ukuthi kungafinyelelwa?

Izinhlobo eziningi zezinto ezibonakalayo azinakufakwa kalula esikhundleni sazo. Ukwakheka kwento nokwakheka kwento ngokuyisisekelo kunquma izakhiwo eziyinhloko zento. Ukusebenza kungathuthukiswa ngokusebenzisa ubuchwepheshe bokucubungula impahla.

Ukuwohloka kwama-polymers kuyinkinga impela. Njengamanje, abacwaningi basebenza kanzima, kepha inqubekela phambili ihamba kancane. Ngekusasa elibonakalayo, ukusetshenziswa kwamapulasitiki kuzolawulwa ezindaweni lapho kungadingekile ukusebenzisa amaplastiki, kepha ayikho indlela yokuyibuyisela kwezinye izindawo ezidingekayo.
