Iseyili

Oseyili bemoto bahlanganisa indwangu yemvula yepulasitiki (PE), indwangu yokukhuhla ummese we-PVC kanye neseyili kakotini.Phakathi kwazo, indwangu yemvula yepulasitiki iye yakhuthazwa kabanzi emalolini ngenxa yezinzuzo zayo zokukhanya, ukushibhile, nobuhle, futhi isiphenduke iseyili lokuqala kubashayeli noma abanikazi bezimoto.Indwangu yemvula yepulasitiki yenziwe nge-polyethylene njengento eluhlaza, futhi igcwaliswa ngezinyathelo ezine zokudweba, ukuluka, ukumboza kanye nemikhiqizo eqediwe.Ungakhetha kanjani indwangu yemvula yepulasitiki evumelana nawe?Lesi sihloko sizobonisa izinkomba ezintathu ezibalulekile zendwangu yemvula yepulasitiki.

1. Izinto zokusetshenziswa

Ikhwalithi yezinto zokusetshenziswa inquma ngokuqondile ukubunjwa kwendwangu yemvula yepulasitiki.I-Polyethylene yizinhlayiya ezingajwayelekile ezicwengiwe futhi zifingqiwe ku-naphtha.Izinhlayiya ezintsha ze-polyethylene zingabantu abasobala futhi abajwayelekile, azinabuthi futhi azinambitheki.Ngakho-ke, lapho ukhetha indwangu yemvula yepulasitiki, zama ukukhetha indwangu yemvula ebonakalayo futhi ecwebezelayo.

2. Ifomula esebenzayo

Ngoba i-polyethylene ingasabela ngamakhemikhali ngemisebe ye-ultraviolet ekukhanyeni nomoya-mpilo osemoyeni.Ngakho-ke, ukwengeza ezinye izithasiselo ezisebenzayo ezifana nezithako ze-anti-UV kanye nama-antioxidants ku-raincloth yepulasitiki akugcini nje ukuthuthukisa izinzuzo zangempela zendwangu yemvula yepulasitiki, kodwa futhi kubambezela izinga lokuguga futhi kwandisa kakhulu impilo yayo.Ngokujula kocwaningo nentuthuko, kuye kwasungulwa ifomula yokumelana nokuhuzuka, ikakhulukazi izinkinga zokungqubuzana nokudonsa umoya ezibhekene nokusetshenziswa kwendwangu yemvula yamaloli.

3. Isisindo nosayizi

Isisindo nokuqina kuhlobene, ukujiya kuya kuba mkhulu, i-tarp inzima kakhulu, futhi okuhambisanayo kuhlala isikhathi eside.
